To achieve the purpose above, the knitted fabric, in which multiple types of yarn bundles formed by horizontal knitting are knitted in the wale direction, is characterized in that these multiple types of yarn bundles are formed from yarn bundles with two or more different colors, and at least two types of yarn bundles are knitted alternately in the course direction and continuously recessed and protruding in the course direction.

Description

Knitted fabric

The present invention relates to a knitted fabric having a specific knitted fabric.

In order to impart decorativeness to clothing, there is a fabric which causes the surface of the fabric to exhibit a different appearance depending on the viewing angle direction, and in the prior art, there are some which alternately arrange yarns of two colors on warp or weft of fabric (patent Reference 1).
Moreover, there are some which use these dyeing | staining differences using the thread | yarn of a different composition for the warp and weft of textiles (refer to patent documents 2 and 3), and these cloths color tone according to a visual angle direction Different visual effects, iridescent tone are obtained.

However, as a technology that changes color depending on the angle, there is no stretchability due to the fabric structure (Patent Document 4), and because it is a double knitted fabric or a warp knitted fabric (vertical knitted fabric) Is hard (Patent Document 5 and Patent Document 6), and the color change effect is reduced, and it becomes relatively expensive such as double weave and double russell, and it is sports clothes and stretches requiring a sense of texture, feeling and low price. There is a problem that it is unsuitable for applications such as casual wear.
In addition, as a decorative fabric realized by a knitted fabric, there is a material having a high decorative effect by developing a fabric having different appearance and color depending on the viewing angle direction in a warp knitted fabric. However, there is a disadvantage that the texture is hard on heavy ground. In the case of a weft knitted fabric (horizontally knitted fabric), it is difficult to construct a fabric having a three-dimensional decorative visual effect by a thin fabric since the surface of the fabric is relatively flat.

Hereinafter, the present invention will be described in detail.

In the present invention, “a knitted fabric in which plural types of yarn bundles knitted by weft knitting are knitted in the direction of wales” means that plural types of yarn bundles form one knitting unit, and a plurality of types of yarn bundles are knitted. The unit is a knitted fabric which is repeatedly woven in the direction of the wales of the knitted fabric. Here, to be knitted in the wale direction is to be knitted while switching a plurality of types of yarn bundles one by one in the advancing direction in which the knitting is advanced. A plurality of types of yarn bundles are knitting units for characterizing the knitted fabric, and are, for example, knitting units that form a rib-like uneven or wave-like shape. The combination of materials and characteristics such as fineness, hue, shrinkability and extensibility is important for a plurality of types of yarn bundles, and each yarn bundle may be different or the same. However, as described later, at least one (seed) yarn bundle needs to be different in hue from other yarn bundles. For each yarn bundle, the same yarn bundle may be used depending on the role in the knitting unit.
In the description using drawings to be described later, in a plurality of types of yarn bundles, each yarn bundle is described as a, b, c, d, e. For example, two yarn bundles are represented by a and b, and four yarn bundles are represented by a, b, c and d. The upper limit number of plural types of yarn bundles is not particularly limited, but considering the frequency of switching the yarn bundles and rib-like irregularities formed on the knitted fabric, it is preferably up to eight, more preferably four. . Next, to be knitted by weft knitting means that plural kinds of yarns are sequentially knitted in the weft direction, but, for example, four kinds of yarn bundles of a, b, c, d are used as a repeating unit. It means that knitting is formed. Furthermore, as described later, it is preferable that four types of yarn bundles, a, b, c, and d, constitute one knitting unit, and form a convex-concave shape of one cycle. This is because a regular and stable thickness knitted fabric can be obtained by forming a concavo-convex shape with four types of repeating units. The number of courses formed by a plurality of yarn bundles of a, b, c and d depends on the thickness and knitting method of the yarn bundles, but can be switched to the next yarn bundle in several courses at most 12 courses. The method of switching the yarn bundle may be a method used in a general horizontal knitting machine (round knitting machine). The yarn bundles of a, b, c and d form areas when they are woven for several courses, so in the knitted fabric they are also called a part, b part, c part and d part respectively, a, b, c, How to count d may be "seed" or "site".
At least one yarn bundle among a plurality of yarn bundles has a hue different from that of the other yarn bundles in a knitted fabric in which a plurality of yarn bundles knitted by weft knitting are knitted in the wale direction. A plurality of types of yarn bundles do not all have the same hue, and some types of yarn bundles are in the state of being composed of yarn bundles different in hue from other yarn bundles. When four types of yarn, a, b, c, d, are used as repeating units, for example, when a is a color different from b, c, and d, a, c, b, d, Also includes cases of different colors. The number of yarn bundles having a hue different from one another may be one or two. The position (order) at which the yarn bundles of different hues are arranged may or may not be adjacent to a. The number of hues of the plurality of yarn bundles may be a number of suitable colors that satisfy the configuration that makes the colors appear different depending on the angles described later. That is, in the case of four types, among the plurality of thread bundles, the number of thread bundles having a color different from that of the other thread bundles may be appropriately selected so that a color change appears. There may be different hues.
Next, formation of rib-like irregularities in the course direction will be described. It is important that the knitted fabric of the present invention is a knitted fabric in which at least two types of yarn bundles are knitted alternately in the course direction and continuously form unevenness in the course direction.
The use of a plurality of types of yarn bundles means that the knitted fabric can form irregularities continuously in the course direction by regularly and repeatedly arranging the yarn bundles having different contraction rates and extensibility in the course direction. Regularly repeating includes repeating alternately depending on the number and arrangement pattern of a plurality of types of yarn bundles. In the present invention, “arrange yarn bundles different in contraction rate and extensibility in the course direction” means that the contraction rates and elongation rates of adjacent yarn bundles are different from each other among multiple types of yarn bundles, and the contraction rates And yarn bundles with different extensibility are alternately arranged. When two or more types of yarn bundles are used, by alternately arranging yarn bundles different in contraction rate and extensibility, it becomes a knitted fabric which forms regular unevenness in the course direction. When three or more kinds of yarn bundles are contained, one kind of yarn bundle different in contraction rate and extensibility from others is contained, and three kinds of yarn bundles are repeatedly arranged in the course direction to continuously form unevenness in the course direction It is preferable to make it wavy. When four or more types of thread bundles are included, one or two types of thread bundles having different contraction rates and extensibility are included, and four types of thread bundles are repeatedly arranged in the course direction to continuously form irregularities. It is preferable to When four or more types of yarn bundles are used, the effect of forming irregularities by yarn bundles having different contraction rates and elongation rates is obtained at four locations: convex and concave portions, and both sides from convex to concave and concave to convex It is particularly preferable because it can be configured.
As will be described later, a yarn bundle having a high shrinkage ratio and extensibility can be obtained by adding a yarn having contraction elasticity to the yarn of the base. Therefore, functions can be added independently of the hues of the plurality of types of yarn bundles described above. As a result, the number and arrangement pattern of yarn bundles different in shrinkage ratio and extensibility can be determined independently of the hue possessed by a plurality of yarn bundles, so that different color effects can be easily obtained by a plurality of yarn bundles, It is preferable to design the uneven shape. The unevenness height of this knitted fabric may be changed as appropriate depending on the use, but when used for clothing, the height of unevenness (height from concave to convex) is 0.3 to 3.0 mm. The range is preferred, more preferably 0.3 to 1.5 mm. When used as materials such as curtains and covers, the range of 0.3 to 4.0 mm is preferable, and more preferably 0.3 to 2.5 mm. Here, the height of the unevenness is a value obtained by depth measurement using a microscope. If it is less than 0.3 mm, the depth of unevenness is insufficient and it is difficult to obtain the hue effect. When it exceeds 3 mm or 4 mm, the convex portion is easily crushed and it is difficult to obtain a hue effect.
Next, respective yarns constituting a plurality of types of yarn bundles (a, b, c, d, e,...) Will be described. The yarn bundle often consists of a plurality of yarns. In the following description, for convenience, each yarn is represented as yarn (1), yarn (2), yarn (3), yarn (4), yarn (5), yarn ... yarn (n) . The yarn (1) to the yarn (n) are yarns having different properties such as material, fineness, hue, shrinkage, and extensibility. Each of the plurality of types of yarn bundles is composed of one or more yarns from yarn (1) to yarn (n). One kind of yarn bundle (a, b, c, d or e...) Among the plurality of kinds of yarn bundles is selected from any yarn from yarn (1) to yarn (n). In the present invention, it is preferable to combine, for example, the yarn (1) and the yarn (2) to form one kind of yarn bundle (a) in consideration of the two effects of the color effect and the uneven formation. The same yarn may be used for all of the plurality of yarn bundles, and different yarns may be used in combination depending on the purpose.
Here, as an example, the yarns (1) to (4) have low shrinkage and extensibility, and the yarn (5) has high shrinkage and high extensibility. In the case where there are four types of yarn bundles, yarns (1) to (4) are placed in a to d, respectively, and yarn (5) is placed on a in combination with yarn (1) alone. Then, one of a plurality of types of yarn bundles including the yarn (1) and the yarn (5): a is easily shrunk and its extensibility also becomes high. That is, in the case of the yarn bundle including the yarn (5), the yarn bundle is shrunk to be a three-dimensional knitted fabric. A knitted fabric having a yarn bundle in which a yarn (5) having a high contraction rate is combined with any one of a plurality of yarn bundles is likely to be recessed or lifted from a plane at the yarn bundle. In addition, in relation to the hues of the plurality of yarn bundles described above, it is sufficient that one kind is a yarn bundle of a hue different from another, but according to the knitting unit of plural kinds of yarn bundles, yarn bundles of different colors are always convex It will be formed in a part or recess, and will be formed in the remaining recess or convex part, the side surface between convex and concave, and the side surface between concave and convex.
Hereinafter, the configuration of the yarn in the yarn bundle, the configuration of a plurality of yarn bundles, and the rib-like unevenness will be described using the knitted fabric shown in FIG. 1A.
FIG. 1A is a schematic view showing an example of a knitted fabric which forms the concavo-convex shape of the present invention. FIG. 1A is an image view of a knitted fabric as viewed from the surface, and FIG. 1B is a cross-sectional image view of the knitted fabric when cut in the course direction. FIG. 1C is a sectional image view in which a part of FIG. 1B is enlarged. In FIG. 1A, in the knitted fabric 10, plural kinds of yarn bundles and four kinds (a, b, c, d) repeat in the course direction, and a to d are continuous on the knitting ground.
Plural kinds of yarn bundles use five yarns of yarn (1) to yarn (5) in total.
The color and shrinkage of yarn (1) to yarn (5) are as follows: yarn (1): yellow, shrinkage small yarn (2): blue, shrinkage small yarn (3): yellow, shrinkage small Yarn (4): blue, shrinkage small yarn (5): white, large shrinkage.
The combination of yarn (1) to yarn (4) in a plurality of yarn bundles (a, b, c, d) is as follows: a: yarn (1) and yarn (5), yellow b: yarn () 2) and yarn (5), blue c: yarn (3) and yarn (5), yellow d: yarn (4), blue.
In FIG. 1A, in the knitted fabric 10, the lateral direction is the wale direction, and the longitudinal direction is the course direction. a is a course including two yarns of yarn (1) and yarn (5), and the yarn bundle a is easily contracted by the action of the yarn (5). The color is yellow. b is a course including two yarns of yarn (2) and yarn (5), and the yarn bundle b is easily shrunk by the action of the yarn (5). The color is blue c is a course including two yarns of yarn (3) and yarn (5), and the yarn bundle c is easily shrunk by the action of the yarn (5). The color is yellow. d is a course including only the yarn (4) and not including the yarn (5) having a large contraction rate. Although d is one thread, it may include a plurality of threads. The color is blue. The yarn bundle a is knitted in a plurality of courses, but is preferably 1 or more and 10 or less. The same applies to the other yarn bundles b, c and d. In FIG. 1A, although there is a space between a and b for the sake of clarity, a plurality of yarn bundles are continuously arranged without a space in the course direction. Thus, at least one of the plurality of yarn bundles (a, b, c, d) has a hue different from that of the other yarn bundles, and at least two yarn bundles alternate in the course direction. It is organized into
FIG. 1B is a cross-sectional image view between course direction AA in the knitted fabric 10 of FIG. 1A. The needle surface 11, which is the front surface, is indicated by an arrow. As shown in FIG. 1B, in the knitted fabric of the present invention, the cross-sectional shape in the course direction is rib-like irregularities. The height H is measured using the distance from the highest protrusion to the lowest recess as the height.
FIG. 1C shows the positional relationship between a plurality of types of thread bundles and the shape of the unevenness. The yarn a including the yarn (1) and the yarn (5) is located on the side surface of the rib-like unevenness. The b including the yarn (2) and the yarn (5) is located in the recessed portion of the unevenness viewed from the surface (here, the needle surface 11). C containing the yarn (3) and the yarn (5) is located on the side of the rib-like unevenness. The d including the thread (4) is located in the convex portion of the concavo-convex viewed from the needle surface 11. In one embodiment, a, b and c including the easily shrinkable yarn (5) are contracted to lift d which is difficult to be shrunk to form a protrusion. The positions on the unevenness of a to d can be controlled to be a specific position from the contraction rate of the yarn and the like, and the positional relationship between the unevenness formed continuously in the course direction and the yarn bundle is regular. In addition, a front convex part is d of FIG. 1A, and a back convex part (concave part) is formed of b part of FIG. 1A.
Also, by arranging at least one yarn bundle with different hue in any of a to d, it is possible to have a plurality of colors in the same knitted fabric. And the structure which arrange | positions a specific thread bundle, ie, the color of a specific hue, in the specific place of uneven shape is obtained. In FIG. 1C, since a and c are yellow and b and d are blue, when the viewer looks at the knitted fabric from the front, it looks like blue of b and d of the concavities and convexities, and the observer looks obliquely from the knitted fabric And, in addition to blue, it looks yellowish, so it looks greenish as a whole. When a to d include yarns of two or more hues having different hues, the hue changes slightly depending on the viewing angle because the hue changes in various colors, which is more preferable. In addition, yarns of two or more hues having different hues form a pattern or a pattern, and the pattern changes depending on the viewing angle, which is more preferable.
By combining the uneven shape of the knitted fabric and a plurality of hues, it is possible to create a knitted fabric whose color or pattern changes depending on the viewing angle. Here, although the surface is described as the needle surface 11, it is also possible to use the sinker surface as a surface in the product. If the sinker surface is the product table, the arrangement and design of yarns in the product table will be reversed.

A rib-like front convex portion (d in FIG. 1B) projecting to the front side along the wale direction and a rib-like back convex portion (front concavity, b in FIG. 1B) similarly curved and projected to the back side along the wale direction And the shape of the cut surface along the course direction is formed in a wavelike shape as in a repetition of abcdabcd as shown in FIG. 1, C knitted fabric cross-sectional image enlarged view). Knitted fabrics are preferably used.
Here, the state in which the color changes depending on the viewing angle will be described. By forming the concavities and convexities in a rib shape, it is possible to hide the color in the concave part and the color on the opposite side to the visual direction of the convex part depending on the relationship between the viewing angle and the convex part. For example, when viewed from the front, the color of the rib-like convex and concave is easily visible, and when viewed obliquely from above, the color of the side of the convex is easily visible, and the side opposite to the visual direction of the convex is The color is hard to see.
In addition, the rib-like shape can be set arbitrarily, and in order to form fine short pitches and thin rib-like irregularities, using a high gauge knitting machine or shortening the repetition interval of the yarn It can correspond by. Moreover, in order to make it large rib-shaped uneven | corrugated shape, a low gauge knitting machine may be used and the repetition interval of thread | yarn should be enlarged. Further, it is also possible to make the front convex portion large and wide, and to form the back convex portion (front concave portion) at an arbitrary place and at an arbitrary interval. In addition, rib-like unevenness can also adjust the interval with the pre-set and finish set at the time of dyeing processing, and by shrinking the back convex part (front concave part), the back convex part (front concave part) is difficult to see, It is also possible to set it as the knitted fabric which a back convex part (front concave part) appears when it is made to extend.
As described above, at least one yarn bundle of the plurality of yarn bundles (a, b, c, d) has a different hue from that of the other yarn bundles, and comprises at least two of the plural yarn bundles (a, b, c, d). Seed yarn bundles are knitted alternately in the course direction. A knitted fabric knitted by weft knitting while controlling its hue and surface unevenness has good stretchability and texture, and has an effect because the color and pattern change depending on the viewing angle.
Another embodiment is described using FIGS. 2A and 2B and FIGS. 3A and 3B.
FIG. 2A is an example of a knitted fabric in which a2 including yarn (1) and yarn (5) has different colors, and a2 is disposed in the front concave portion (see FIG. 2B).
A plurality of yarn bundles use a total of five yarns.
The color and shrinkage of yarn (1) to yarn (5) are as follows: yarn (1): yellow, shrinkage small yarn (2): blue, shrinkage small yarn (3): blue, shrinkage small Yarn (4): blue, shrinkage small yarn (5): white, large shrinkage.
The combination of yarns in a plurality of yarn bundles (a, b, c, d) is as follows: a2: yarn (1) and yarn (5), yellow b2: yarn (2) and yarn (5), Blue c2: Yarn (3), Blue d2: Yarn (4) and Yarn (5), Blue.
FIG. 3A shows that a3 containing yarn (1) and yarn (5) and c3 containing yarn (3) and yarn (5) have different colors, and a3 and c3 on the side surfaces on both sides of the convex portion of the uneven shape. It is an example of the arranged fabric.
Plural kinds of yarn bundles use five yarns of yarn (1) to yarn (5) in total.
The color and shrinkage of yarn (1) to yarn (5) are as follows: yarn (1): yellow, shrinkage small yarn (2): blue, shrinkage small yarn (3): white, shrinkage small Yarn (4): blue, shrinkage small yarn (5): white, large shrinkage.
The combination of yarn (1) to yarn (4) in a plurality of yarn bundles (a, b, c, d) is as follows: a3: yarn (1) and yarn (5), yellow b3: yarn (3) 2) and yarn (5), blue c3: yarn (3) and yarn (5), white d3: yarn (4), blue.
In FIG. 2A, the stitches of the yarn bundle a including the yarn (1) and the yarn (5) are disposed at the position of a2 which is the front concave portion, the yarn (3) is positioned at the front convex portion c2, and the other yarns are Located at b2 and d2. In FIG. 3A, the stitch by the yarn bundle b including the yarn (2) and the yarn (5) is positioned at b3 of the front concave portion, and the stitch by the yarn bundle d including yarn (4) is positioned at d3 of the front convex portion . The stitches of the yarn bundle a including the yarn (1) and the yarn (5) are located at a3 on the side of the convex portion. The stitches of the yarn bundle c including the yarn (3) and the yarn (5) are located at c3 (the other side of the convex portion). Here, a2 to d2 may be one course or plural courses. Further, a2 to b2, b2 to c2, c2 to d2, and d2 to a2 are continuous on the knitting ground. The same applies to a3 to d3.
In the embodiment of FIG. 2A, the knitted fabric is a weft knit and has good extensibility because the surface irregularities expand and contract. Furthermore, when the fabric is viewed from the front, blue and yellow are observed, and when the fabric is viewed obliquely, it is observed as blue. Also, when the surface unevenness of the knitted fabric is elongated, yellow is often observed. In this way, a knitted fabric having good stretchability in which the hue changes depending on the viewing angle can be obtained.
In the embodiment of FIG. 3A, the knitted fabric is a weft knit and has good extensibility because the surface irregularities expand and contract. Furthermore, when viewing the knitted fabric from the front, blue is observed, when viewing the knitted fabric obliquely, yellow is observed, and when viewing the knitted fabric obliquely from the opposite direction, white is observed. In this way, a knitted fabric having good stretchability in which the hue changes depending on the viewing angle can be obtained.
FIG. 4 is a schematic view showing an example of a knitted fabric forming the concavo-convex shape of the present invention, FIG. 4A is a photograph of the knitted fabric seen from the surface, and FIG. 4B is a knitted fabric when cut in the course direction. It is a cross section photograph.

The method in which a plurality of types of yarn bundles have two or more colors is not limited to the following, but at least two types of yarn bundles alternately woven in the course direction are two or more types of yarn bundles having different dyeability. Is preferred. It is preferable that yarns having different dyeability be used in the yarns used for the respective yarn bundles. Although each yarn bundle (a, b, c, d) uses a plurality of yarns (Yarn (1), Yarn (2), Yarn (3), etc.), the dyeability of one yarn is It is preferable that it is different from others. And, different hues to be formed in the knitted fabric can be set by dyeing. This can correspond to a plurality of colors in the same living machine, and can also cope with the request of various types of small lots. In addition, it is advantageous to be able to set the color in the dyeing process, since it is possible to secure the living machine as a stock and to be able to shorten the delivery time to be able to correspond to the color and the amount. Here, the term "different in dyeability" means yarns that are not dyed in the same color by the same dyeing method or the same dye, and yarns that are dyed by dyeing by the different dyeing method or the different dye. For example, a knitted fabric using nylon yarn and rayon yarn can be dyed by alternately dyeing with an acid dye and a direct dye. In addition, in the case of using polyester base yarn and nylon, by dyeing only nylon with an acid dye or a direct dye, a knitted fabric having two or more hues can be obtained.

By dyeing the knitted fabric by different dyeing methods, it is preferable to design so that there are two or more different portions of different hues in the knitted fabric, and the color and pattern change depending on the viewing angle. For example, by changing the hue of the convex apex and the base of the concave portion of the fabric forming the unevenness in the course direction, the concave portion is hidden by the convex depending on the viewing angle, and the color of the concave can not be seen . As a result, the color of the concave portion appears depending on the viewing angle. As another example, by arranging yarns having different hues on the rib-like side surfaces forming the convex portion, the color of one side surface is hidden by the viewing angle. As a result, the color of the concave portion appears depending on the viewing angle.

Here, more preferably, it is a knitted fabric having three or more hues. By having three or more hues, it is because the change in color is emphasized when the angle is changed, when the angle is changed in the opposite direction, when viewed from the front, and when it is viewed from the front. When the angle is changed, the color and angle arranged on the side of one side of the rib-shaped unevenness are reversed, when the angle is changed from the surface to the center of the hue of the front convex portion and the back convex portion (front concave portion). The color is arranged on the other side of the rib-like unevenness to emphasize the change in color.
The yarn (1) to the yarn (4) may be any one that can be used as a knitted fabric such as nylon yarn, polyester yarn, rayon yarn and the like. In addition, in order to change dyeability for every yarn in a knitted fabric, two or more types of raw materials are preferably used.

Polyurethane elastic yarn, or covering yarn using polyurethane elastic yarn, or high contraction yarn having a boiling water contraction ratio of 10% or more as a yarn (5) having a large contraction ratio and extensibility It is preferable to use a yarn partially disposed. A more preferable range of the high shrinkage yarn is a boiling water shrinkage of 10% or more and 30% or less.
The rib-like concavo-convex shape, which is a feature of this knitted fabric, alternately arranges polyester or normal nylon yarns and yarns such as polyurethane elastic yarns that differ in extensibility and heat shrinkage, in the course direction of the knitted fabric. It becomes a knitted fabric that partially shrinks. Thereby, rib-shaped unevenness can be formed on the knitted fabric. More preferably, a yarn such as polyurethane elastic yarn different in extensibility and heat shrinkable yarn is plated with nylon yarn or polyester yarn with plait knitting, or high contraction yarn is reversible texture (face-to-face alignment). By arranging the front and back tissue partially, it is possible to form a clean asperity. In this case, it is preferable that the shrinkage characteristics of the normal polyester or normal nylon yarn have a boiling water shrinkage of 10% or less. Here, although a polyurethane elastic yarn is preferable, rib-shaped unevenness can also be formed using a copolyester yarn having a high thermal contraction rate, a nylon yarn having a high thermal contraction rate, or the like.

When used in a sewn product, the wales of the knitted fabric may be used as the border with the weft direction of the sewn product, but the wales of the knitted fabric may be used as stripes in the warp direction of the sewn product. You may use it. By using it in the form of stripes, when it is used as a clothing item, it becomes a fabric with different colors on the left and right. Here, sewing products include sportswear and swimwear, bottoms, clothing products such as coats and sewing products, bags, shoes, accessories such as hats and scarves, cushions and covers, curtains and the like. It can also be used as a material for materials such as upholstery such as sheet materials and table hooks.

In the knitted fabric of the present invention, various yarns used in the conventional knitted fabric, for example, yarns of various synthetic fibers, filament yarns of regenerated fibers, natural fibers, artificial fibers, and yarns comprising those fibers, polyurethane ( Elastic yarns such as spandex yarns can be used, and further, yarns may be used as covering yarns and covering yarns, and may be optionally used according to the purpose. In a fabric partially shrunk by using false twisted yarn or crimped yarn, a portion with a small shrinkage is preferably used because it gives a plain surface feeling. On the other hand, it is also possible to use a flat yarn which is not easily shrunk at a portion where the shrinkage is small, to produce a texture of a woven and football-like texture. Moreover, it can be used according to the purpose and processing method, such as a primary binding yarn and a pre-dyed yarn.
The fineness of the above-mentioned fiber is not particularly limited, and commercially available ones can be used according to the purpose, but in order to make the texture soft, it is preferable to make the single yarn fineness 1.5 dtex or less. More preferably, when the fineness is 0.1 dtex or more and the fineness of the single yarn is too small, the coloring property becomes small, and the range which can be used for clothing or material use becomes narrow. The above-mentioned fibers may also contain additives such as titanium oxide as a matting agent, but they do not contain a matting agent for the purpose of obtaining a knitted fabric having a color with high saturation in hue. Bright yarn is preferred.

Since the surface and the back of the fabric are uneven, the fabric has excellent stretchability, and since the rib-like uneven portion has less surface to hit the skin, it suppresses stickiness at the time of sweating, and the concave is always air Because it has a large surface area, it is also excellent in quick drying. Furthermore, it is possible to diffuse absorbed sweat by using a water-absorbing quick-drying functional yarn such as a yarn of irregular cross-section or a yarn having a large number of filaments, and to obtain further rapid drying. Also, if the surface convex portion is knitted with hydrophilic fibers and the back convex portion (surface concave portion) with hydrophobic fibers, the sweat absorbed by the convex portion is quickly transferred to the front side and evaporated, and the stickiness at the time of sweating is effectively suppressed and further You can get comfort. It is suitable not only for the design of color change but also for the use of clothing such as sportswear and knitwear as functional materials.

In the knitted fabric of the present invention, by using a single knitting machine, it is possible to create a thin, light-weight knitted fabric. By making it thin and light in weight, it becomes a cloth suitable for clothing, and can be used for small products, even when used as covers.

As a knitting machine to be used, any knitting machine that can obtain the target of the present invention can be used, and in particular, a circular knitting machine and a horizontal knitting machine are preferable. Besides, it is also possible to knit with a sock knitting machine, and furthermore, it is also possible to partially create this knitting form using a non-sewing knitting machine such as a special circular knitting machine made by Santoni or a wholesale garment made by Shima Seiki is there.

The knitted fabric structure is not limited as long as a knitted fabric can be obtained, but it is not limited, but it is a modified reversible pummel structure formed by plating two yarns partially, a deformed bare pimp fabric, a deformed bare deerskin, a deformed bare mesh Single knits are preferably used.

The measuring method of the characteristic value used in the Example is demonstrated below.
(1) Ventilation rate:
The air flow rate was measured by fiscal 2015 JIS-L-1096 (Frazil method). The aeration amount is represented by the amount of gas per unit area [cc / cm ² / sec] per second. The measurement was performed at a temperature of 20 ° C. and a humidity of 65 RH%.
(2) Back side water retention rate:
1.0 cc of distilled water was dropped on a glass plate, and a knitted fabric with a sample size of 10 cm × 10 cm was placed thereon with the back surface facing downward in contact with distilled water. After standing for 60 seconds, this knitted fabric was transferred onto another glass plate, sandwiched between two sheets of filter paper cut to the same size, and left for 60 seconds with a load of 5 g / m ² applied. Thereafter, the water holding mass of the knitted fabric was calculated from the difference between the original knitted fabric mass and the knitted fabric mass after water absorption. Further, the water retention rates of the front and back surfaces of the knitted fabric were calculated from the water-containing mass of each filter paper in contact with the front and back surfaces. Such an operation was similarly performed about three knit fabrics, and let an average value be a back surface water retention rate. In addition, a back surface shows the surface which a knitted fabric contacts with the skin.

When the back surface water retention rate is small, the dropped distilled water is efficiently moved to the surface side, and the so-called water permeability is excellent and there is little stickiness when worn. The back side water retention rate is evaluated as follows. A: Back side water retention rate less than 20% B: Back side water retention rate 20% or more.
(3) Collect 3 test pieces of about 15 cm × 15 cm in size from the water-absorbent fabric, and place each skin on the skin side up so that no extra tension is applied to the embroidery frame or beaker with a diameter of 10 cm or more. And place the sample so that the surface of the test piece is horizontal. The measurement was performed at a temperature of 20 ° C.

In addition, a test piece in which the tip of the injection needle (TERUMO 26G1 / 2, 0.45 × 13 mm, syringe capacity 1 cc) adjusted so that 1 drop (about 0.005 cc) of distilled water is dropped vertically is placed horizontally It fixes to a predetermined holder so that 5 cm away from the surface of.

In this state, when one drop of water drops is dropped on the test piece, the water absorption time until the water drop on the test piece stops special reflection is measured with a stopwatch and read in 0.1 second units. Here, the "no special reflection" state means that the specular reflection disappears as the test piece absorbs the water drop, and only the wetting remains.

The above operation is performed on all the test pieces, and the average value of the water absorption rate is taken as the water absorption rate of the knitted fabric.
(4) Evaluate using fast-drying diffusible residual moisture content. First, three test pieces of 10 cm × 10 cm in size are collected from a knitted fabric conditioned at a temperature of 20 ° C. and a humidity of 65% RH, and then the weight of each test piece is measured and used as the original weight.

Subsequently, 0.3 ml of distilled water is dropped on a glass plate, and the skin surface of the test piece is placed in contact with the distilled water and left for 5 seconds.

Five seconds after the test piece is placed on the glass plate as described above, immediately after the test piece is hung on a hanger type weighing, the weight is measured. Thereafter, the weight of the test piece is measured every 5 minutes. In addition, the measured value of weight is calculated to the third decimal place. Then, the diffusible residual water content (%) defined by the following equation is calculated by using the weight measured every 5 minutes and the original weight.

Diffusive residual moisture percentage (%)
= {[Weight at measurement-original weight] / [weight at start of measurement-original weight]} x 100
The weight measurement of the test piece every 5 minutes and the calculation of the diffusible residual water content are continuously performed until the value of the diffusible residual water content becomes 10% or less, and the measurement when the value becomes 10% or less Ask for time.

The above operation is performed on all the test pieces, and the average value of the obtained measurement time (measurement time when the residual diffusive moisture content is 10% or less) is calculated.
(5) Unevenness height (mm)
The height from the concave part to the convex part is a magnification of 100 times (VH-ZST lens) using a microscope VHX-5000 manufactured by Keyence, and the knitted fabric is photographed from the surface, and the depth is measured from the highest convex part to the lowest. The height to the recess was measured.
(6) Boiling water shrinkage rate The measurement was performed in the state of a yarn. Similar to the method of the dimensional change rate of hot water in the method of JIS L1013 (2010 version), the dimensional change rate was evaluated using hot water of 98 ° C. as boiling water.
