Description

  The present invention relates to a knitted fabric for business shirts that is excellent in stretch (stretchability), breathability, and sheer prevention while having firmness and stiffness.

  Shirts worn mainly in the business scene, such as conventional shirts, dress shirts, casual shirts, blouse, etc., are woven fabrics in which wefts are woven with warp yarns orthogonal to warp yarns. It is used. The reason for this is that the woven fabric is excellent in silhouette because it has a fine texture, is firm, and is strong. However, since the warp and the weft are closely crossed and tightly bound to each other, the air permeability is poor, and the inferior flexibility and stretchability are factors that impede comfort during wearing. For example, during summer commuting, when working outside, or when performing operations that involve hard movements, sweat that perspires is not easily dissipated to the outside, making it easy to get stuffy or sticky, and is not flexible. There is a problem that the fabric tends to stick to the skin and the comfort tends to be inferior.

In order to solve such a problem, the present applicant tried to make a fabric for a business shirt with a knitted fabric, and was a knitted knitted fabric of spun yarn and filament, and was bent per basis weight in the vertical and horizontal directions. Proposed knitted fabric for business shirts having a stiffness (B / M) of 1.7 × 10 ⁻⁴ or more, an elongation rate (EMT) of 10% or more, and a bending back property (2HB) of 0.060 gfcm / cm or less ( Patent Document 1). Although this method can provide a knitted fabric for business shirts that has moderate elasticity and stiffness, and is excellent in water-absorbing quick-drying and skin-releasing properties, a filament having no fluff and a spun yarn having a lot of surface fluff are mixed. There is a problem in that it is necessary to knit and the surface becomes uneven.

Further, the present applicant is formed of a fabric made of a single knit knitted fabric having a basis weight of 155 g / m ² or less and 90 g / m ² or more and a wale density of 30 wales / 2.54 cm or more. The present inventors have proposed a knitted fabric knitted with a composite yarn having a fine count of 30/1 or less composed of spun yarn and filament yarn (see Patent Document 2). However, this method also requires the use of long and short composite spun yarns composed of short fibers and filaments.

  Further, as an attempt by devising the knitting structure, a single circular knitted fabric composed of a front yarn and a back yarn has been proposed (see Patent Document 3). This knitted fabric is characterized in that on the sinker loop surface, there is a bridging portion in which the distance between the bridging portions between the stitches by the welt is 1 stitch or more and 8 stitches or less. However, according to this method, there is a problem that the knitted fabric becomes thick due to the structure of the front yarn and the back yarn. In addition, since there are many tengu stitches, there has been a problem that the elongation of the knitted fabric is increased and the shape retention is liable to be lowered.

  The present invention has been made in view of the above-described problems of the prior art, and its purpose is to limit the elongation in the warp direction while being a knitted fabric, and to achieve a moderate elongation and softness as a business shirt. It is to provide a knitted fabric having air permeability and shape retention. Furthermore, the objective of this invention is providing the knitted fabric for business shirts with little translucency, although it is a thin knitted fabric.

  In order to achieve the above object, the present inventors have intensively studied to make a thin knitted fabric for the purpose of serving as a business shirt, and as a result, adopted a single knitted fabric and accounted for all of the basic organization of the knitted fabric. By setting the ratio of the number of knit loops and the total number of welts to a knitted pattern structure within a specific range, and appropriately setting the course density, the wale density, the warp direction and the warp direction (EMT), It has been found that it can provide a knitted fabric for business shirts that has high shape retention, moderate elasticity and stiffness, and is difficult to see through, while maintaining the flexibility of the fabric, and the elongation in the warp direction decreases. The invention has been completed.

That is, the present invention has the following configurations (1) to (5).
(1) The knitted fabric basic structure is a single knitted fabric having a pattern structure in which the ratio of the number of welts to the number of knit loops is 0.20 to 1.10. 30 to 80 pieces / 2.54 cm, and the vertical stretch rate (EMT) is 3 to 25%, and the horizontal stretch rate (EMT) is 8 to 40%. Knitted fabric.
(2) The business shirt knitted fabric according to (1), comprising 3 to 25% by weight of polyester filaments having a single yarn fineness of 3 to 12 dtex and a total fineness of 30 to 120 dtex.
(3) The ground part is made of polyester fiber containing 0.6 to 5.0% by weight of white metal oxide, and the handle part is made of polyester fiber containing 0 to 0.5% by weight of white metal oxide. The business shirt knitted fabric according to any one of (1) to (3).
(4) The ground portion is made of a polyester fiber containing 0.6 to 5.0% by weight of a white metal oxide, and the handle portion is made of a cationic dye-dyeable polyester fiber (1) to (3) The knitted fabric for business shirts as described in any one of.
(5) A business shirt using the knitted fabric for a business shirt according to any one of (1) to (4) as a body.

  According to the present invention, for example, by using a full-polyester false twisted yarn containing titanium oxide fine particles having excellent anti-penetration properties, the shape retention in the warp direction and the excellent anti-peeling property, which are important as a business shirt, and the knitted pattern It is possible to provide a knitted fabric for a business shirt having flexibility and high air permeability that are not found in a woven fabric, while having the aesthetic properties described above.

  Traditionally, knitted fabrics are characterized by high breathability and high flexibility, especially circular knitted fabrics, where the degree of elongation of the background is too large and the silhouette when worn is not clean and has shape retention. It tends to be low. The present inventor has adopted a specific knitting structure that can adjust the stretch rate of the process, particularly the stretch rate in the vertical direction, to a specific range in the knitted fabric of the pattern used for the business shirt, and the silhouette and shape retention of the business shirt. The present inventors have found a knitted fabric suitable for a business shirt satisfying wearing comfort. The business shirt here is a shirt that does not feel uncomfortable even in a general business scene, for example, a shirt that is allowed to wear at a level that is not rude even in interviews between companies. Examples of the form of the shirt include those with specifications such as a bag and a placket.

  In knitted fabrics, following the elasticity of the skin and the bending and stretching of joints when the body is moved greatly affects the wearing comfort. Polo shirts and sports shirts that have traditionally been used for knitted fabrics tend to follow the movement of the body and become comfortable when the degree of progress is high. However, in business shirts that have traditionally used textiles, it is important to reduce the degree of progress, especially in the vertical direction, in order to obtain the firmness, stiffness, silhouette and shape retention of the dress shirt. It is. As a result of verifying the optimum background / elongation region of the knitted fabric used for the business shirt in the wearing test, the present inventor has obtained a relatively low elongation in the vertical direction (EMT) and the horizontal direction (EMT). It was found that it was necessary to make the range of degrees.

  Specifically, in the knitted fabric of the present invention, the elongation in the warp direction (EMT) is 3 to 25%, preferably 5 to 20%, more preferably 8 to 18%. If the elongation rate (EMT) in the vertical direction exceeds the above range, it will lead to a decrease in the firmness and firmness of the fabric and the shape retention of the product. When the elongation in the vertical direction (EMT) is less than the above range, it is not possible to obtain an appropriate elongation required for wearing a business shirt, and it is difficult to achieve the object of the present invention.

  Moreover, in the knitted fabric of this invention, the elongation rate (EMT) of a horizontal direction is 8 to 40%, Preferably it is 10 to 30%, More preferably, it is 11 to 25%. If the stretch rate (EMT) in the horizontal direction is within this range, the flexibility of the knitted fabric is utilized in the shirt, and wearing comfort is obtained. When the elongation rate (EMT) in the horizontal direction is less than the above range, comfort during wearing is lost. Moreover, when the elongation ratio (EMT) in the horizontal direction exceeds the above range, recovery after stretching tends to deteriorate.

  Furthermore, in the knitted fabric of the present invention, the average value of the elongation ratio (EMT) in the vertical direction and the horizontal direction is preferably 9 to 25%, and more preferably 9.5 to 23, as a circular knitting. %, More preferably 10 to 22%. When the average value of the elongation rate (EMT) exceeds the above range, the knitted fabric is stretched and contracted to have a soft texture such as underwear, and the shape retaining property tends to be lowered.

  In woven business shirt fabrics, weave patterns are frequently used, and even in the knitted fabric of the present invention, the woven pattern is reproduced using a semi-jacquard knitting machine or a single knitting machine. In order to realize the rate, it is necessary that the ratio of the number of welts to the number of knit loops is 0.20 to 1.10. Preferably it is 0.25-1.05, More preferably, it is 0.25-1.00. By configuring the welt at a specific ratio with respect to the knit loop in the knitted fabric basic structure, it is possible to suppress stretchability and to exhibit appropriate elasticity and stiffness in the business shirt.

  As a knitting structure of the knitted fabric of the present invention, for example, a check pattern, a staggered pattern, a diamond pattern, a dot, a vertical stripe pattern, a polka dot, and other geometric patterns can be used. When an actual pattern is formed, the knit loop and the welt are set to the above ratios, and as an example of forming the target pattern, the knit-welt knitted structure and the welt ratio are shown in an organization chart. Fig. 1 shows bizarkanoko (welt / knit loop ratio = 0.8), Fig. 2 shows a staggered pattern (welt / knit loop ratio = 0.9), Fig. 3 shows a check pattern (welt / knit loop ratio = 0.26), FIG. 4 shows a dot pattern (welt / knit loop ratio = 0.89) and FIG. 5 shows a vertical stripe pattern (welt / knit loop ratio = 1.00).

  In the present invention, the density design of the knitted fabric is also important. By adjusting the loop density to an appropriate length and width, it is possible to give an appropriate elasticity and stiffness while being a knitted fabric together with the above knitting structure. The knitted fabric of the present invention is knitted with a high gauge single knitting machine and finished to a high density. In the knitted fabric of the present invention, the wale density after dyeing is 30 to 80 pieces / 2.54 cm. Preferably it is 35-70 pieces / 2.54 cm, More preferably, it is 40-65 pieces / 2.54 cm. If the wale density is lower than the above range, the flexibility will be too high and it will be difficult to obtain firmness and stiffness, and if it is higher than the above range, the thread used will be too thin and the fabric will be too thin, or the stretch in the horizontal direction will be It becomes too small and the feeling of wearing can be worse. The knitted fabric course density after dyeing is 40 to 100 pieces / 2.54 cm. Preferably it is 45-85 pieces / 2.54 cm, More preferably, it is 50-80 pieces / 2.54 cm. If the course density is lower than the above range, the flexibility becomes too high and it becomes difficult to obtain firmness and stiffness, and if it is higher than the above range, the dough becomes hard and the air permeability is lowered and the feeling of stuffiness tends to increase. In the knitted fabric of the present invention, the ratio of the course density to the wale density of the knitted fabric is preferably 0.90 to 2.0 when the welded / knit loop ratio is in the above-described range. More preferably, it is 0.95-1.8. If it is less than the above range or exceeds the above range, the elongation rate of the process tends to be out of the appropriate range, and in particular, the elongation rate in the vertical direction tends to be high.

  The knitted fabric of the present invention is preferably knitted by limiting the yarn length per 100 wales (W) in order to keep the degree of warp elongation lower than that of a conventional knitted fabric. The average yarn length of all yarns constituting the knitted fabric is preferably 100 to 170 mm / 100 W. By keeping the ratio of the welt when making a knitted pattern and the length of the yarn constituting the knitted fabric within an appropriate range, shape retention and elasticity can be imparted to the knitted fabric. More preferably, it is 105-150 mm / 100W. If the average yarn length is less than the above range, stable production becomes difficult and knitting defects are likely to occur. Moreover, when the said range is exceeded, the elongation of a knitted fabric will become high and it will become difficult to obtain the effect of this invention.

  The knitted fabric of the present invention can be knitted with high density by using a relatively high gauge circular knitting machine. As the knitting machine used in the present invention, a so-called high gauge single knit knitting machine in which the density (gauge) of the knitting needles in the needle bed is 26 or more per inch (2.54 cm) and the needle bed is in one row. A preferable knitting machine gauge is 28 to 55 pieces / 2.54 cm. A more preferable knitting machine gauge is 32 to 46 pieces / 2.54 cm. When the knitting machine gauge exceeds the above range, it is necessary to use a thinner thread, and a sense of sheer is likely to be obtained. Even if the knitting machine gauge is less than the above range, sheer feeling is likely to be obtained, and the texture tends to be too soft.

  As the yarn constituting the knitted fabric of the present invention, it is preferable to use a filament or a composite yarn including at least a polyester filament. By using the polyester filament, the flexibility and shape retention of the knitted fabric can be further improved. As the polyester filament, a yarn obtained by processing a flat yarn (raw yarn), false twisted yarn, air entangled yarn or the like can be used. From the viewpoint of the softness of the knitted fabric and the prevention of see-through, false twisted yarn is more preferable. As the polyester, polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate and polybutylene terephthalate, and biodegradable fibers such as polylactic acid fiber can be used. Particularly preferred are polyester fibers. These yarns should just be contained 80% or more in a knitted fabric. The cross-sectional shape of the single fiber constituting the yarn of the knitted fabric of the present invention is not limited, and various irregular cross-sections represented by a round shape, a triangular shape, an eight-leaf shape, a flat shape, a Y shape, and the like. Yarn can be used.

  The fineness of the yarn is preferably 30 to 180 dtex, more preferably 50 to 110 dtex. The yarns having different finenesses within the above range may be knit together. When the fiber fineness of the yarn to be used is thinner than the above range, the sense of sheerness of the knitted fabric is increased, and the firmness and stiffness are weakened.When the yarn is thicker than the above range, a thick knitted fabric is obtained. It can be undesirable as a business shirt.

  In the present invention, it is effective to use thick fibers having a single yarn fineness of 3 to 12 dtex, in addition to the above-described measures, in order to further improve the shape retention, elasticity and stiffness. More preferably, it is 5-10 dtex. As a means for mixing, knitting may be carried out, or it may be knitted by blending or spinning with other yarns. It is preferable to mix thick fibers in the knitted fabric at a ratio of 3 to 25% by weight. Since this thick fiber is very hard to bend, if it exceeds 25% by weight, the texture becomes too hard and a Goagoa feeling is likely to become uncomfortable. If it is less than 3% by weight, the effect of increasing the elasticity is reduced. The fiber having a large single fiber fineness may be false twisted, air processed, twisted yarn or the like as long as it is a long fiber, but it is more preferable to use raw yarn. The total fineness of the long fibers is preferably 30 to 120 dtex. More preferably, it is 30-115 dtex. If it is less than the above range, there is little effect of increasing the firmness and stiffness, and if it exceeds the above range, the texture may become too hard.

  For the main yarn of the knitted fabric of the present invention, it is preferable to use a full polyester yarn containing 0.6 to 5.0% by weight of a white metal oxide such as titanium oxide, zinc oxide or zinc sulfate. The knitted fabric of the present invention is thin and is effective for preventing a sense of sheer. The blending rate of the full dull yarn is preferably 30 to 100%. When the mixed rate is low, the sense of sheer is strengthened and the underwear and skin are easily seen and the appearance is poor. Since the knitted fabric of the present invention is a patterned product, the pattern portion should be dyed in a different color, or the pattern portion should be emphasized with a difference in glossiness or sheerness by using fibers or irregular fibers with a low content of white fine particles. Can do. For this reason, it is preferable to use a full dull yarn as appropriate within the range of the above mixing ratio depending on the pattern to be used.

  When using false twisted yarn or twisted yarn for the main yarn of the knitted fabric of the present invention, it is preferable to use both S twist and Z twist. The SZ yarn may be knit, or the SZ yarn may be twisted or aligned and knitted. Shape retention is further improved by mixing S and Z twisted yarns. In addition, since the present invention is intended for a knitted fabric with a high density of thin fabric, skewing tends to occur during dyeing, but there is also an advantage of reducing skewing by using the main yarn in SZ knitting.

  In the knitted fabric of the present invention, a fuller yarn containing 0.6 to 5.0% by weight of a white metal oxide is used in the base part or the handle part, and a cationic dye-dyeable polyester is used in the opposite handle part or the base part. When fibers are used, the pattern portion or the ground portion can be dyed with different colors in a dyeing process after knitting to enhance the pattern or make a pattern. In addition, when a polyester filament containing 0 to 0.5% by weight of a white metal oxide is used for the opposite handle or ground part, the knitted fabric may be dyed in a single color or not. Because the thread has different gloss and light transmission, the pattern can be raised beautifully. However, in this case, it is preferable to use a polyester filament containing 0 to 0.5% by weight of a white metal oxide in a range of 1 to 50% by weight because the sense of sheer is not strong. More preferably, it is 10 to 40% by weight.

Thin fabrics have been preferably used for business shirts, and the knitted fabric of the present invention is required to be light and thin for use as a business shirt. Therefore, a single knitted fabric is used in the present invention. The basis weight of the knitted fabric of the present invention is preferably 80 to 180 g / m ² , more preferably 90 to 160 g / m ² , and still more preferably 95 to 155 g / m ² . If the basis weight exceeds the above range, the thickness dimension becomes too large and the thickness becomes too thick, and it may not be possible to achieve the thinness and lightness required for business shirts. Further, if the basis weight is less than the above range, the firmness and stiffness are weakened, and there is a possibility that an appropriate silhouette as a business shirt cannot be produced. The thickness of the knitted fabric of the present invention is preferably 0.2 to 0.8 mm. More preferably, it is 0.3-0.6 mm, More preferably, it is 0.3-0.5 mm. When the knitted fabric is thinner than the above range, the sense of sheer tends to be too strong, and when the range is exceeded, the flesh feel is too much, and the appearance and the wearing feeling of the casual shirt are likely to become difficult to use for business shirts.

  When dyeing the knitted fabric of the present invention, it may be carried out by a general polyester filament knitted fabric processing method, but in order to suppress the elongation in the warp direction and adjust the balance of the warp and warp elongation, compared to the warp direction. It is preferable that the warp direction is slightly pulled and the knitted fabric loop is finished to be vertically long. The knitted fabric of the present invention may be subjected to predetermined water absorption processing and various functional processing. When the knitted fabric subjected to such special processing is used, it is possible to obtain a business shirt with further improved water absorption quick drying and comfort. Further, the firmness and stiffness can be further increased by performing a hard finishing process such as an acrylic resin, a urethane resin, or a melamine resin in the finishing process.

The mechanical properties of the knitted fabric of the present invention are in accordance with KES (Kawabata's Evaluation System for Fabrics). The stretch rate (EMT) of the knitted fabric of the present invention is measured by KES-FB1. The measurement of the elongation rate (EMT) is performed by holding a 20 cm × 20 cm sample on a chuck with an interval of 5 cm and pulling up to a maximum load of 250 gf / cm at a strain rate of 4.00 × 10 ⁻³ / sec. The knitted fabric of the present invention has a relatively low elongation and is optimal for a business shirt. The longitudinal elongation ratio (EMT) is 3 to 25%, and the lateral elongation ratio (EMT) is 8 to 40%. The average value of the length and width of EMT is preferably 9 to 25%. The knitted fabric of the present invention is characterized by being firm and firm, but can be measured with KES-FB2 as a substitute measure. The vertical and horizontal average values of the B value and the 2HB value are in the range of 0.010 to 0.020 N · cm / cm, and a numerical value range close to a woven fabric can be taken while being a knitted fabric.

The knitted fabric of the present invention can achieve a breathability of 60 cc / cm ² · sec or more while suppressing the sense of sheer. This value is a high value considering that the air permeability of a broad fabric generally used in conventional business shirts is about 20 cc / cm ² · sec.

  Since the knitted fabric of the present invention is difficult to see through, the knitted fabric can be suitably used for a business shirt, particularly for its body. Although the knitted fabric of the present invention is a circular knitted fabric, the see-through prevention degree is 70 or more. Further, by dyeing the pattern portion in light color, the effect of making the pattern stand out and making it difficult to visually see the inside of the shirt can be obtained.

  The business shirt used for the knitted fabric of the present invention is a shirt with a collar that can be used in a business scene. For example, a cutter shirt, a dress shirt, a dress blouse, a button-down shirt, a dungaree shirt, etc. are mentioned. There is no need to have a placket, but a specification with a placket is more formal and easier to use in business situations. Moreover, it is not limited only to the business scene use.

  EXAMPLES The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples. In addition, each performance evaluation in an Example was performed with the following method.

(Knitted fabric density)
JIS-L1096 8.6.2 Based on the density of the knitted fabric, the course density (pieces / 2.54 cm) and the wale density (pieces / 2.54 cm) of the knitted fabric were measured. When measuring visually, the place with the most knit loops on the organization chart in the wale direction (or course direction) was selected, and the number of knit loops was measured to obtain the density.

(Weight of knitted fabric)
The basis weight of the knitted fabric was measured based on the mass per unit area in the standard state of JIS-L1096 8.3.2A method.

(Thickness of knitted fabric)
The thickness of the knitted fabric was measured based on the thickness of the JIS-L1096 8.4A method. The constant pressure under the measurement conditions was set to 23.5 kPa.

(Air permeability)
The air permeability of the knitted fabric was measured in accordance with the air permeability (Fragile type method A method) defined in JIS-L-1096 8.26.1.

(Mechanical properties)
The mechanical properties of the knitted fabric were in accordance with KES (Kawabata's Evaluation System for Fabrics). The stretch rate (EMT) of the knitted fabric was measured with KES-FB1 manufactured by Kato Tech. The elongation rate (EMT) was measured by holding a 20 cm × 20 cm sample on a chuck with a spacing of 5 cm and pulling it to a maximum load of 250 gf / cm at a strain rate of 4.00 × 10 ⁻³ / sec. A fabric that is difficult to stretch has a low EMT value. The bending characteristics were determined by using a KES-FB2 manufactured by Kato Tech Co., Ltd. with a 1 cm width of a predetermined region of each sample as a sample and fixing it between chucks with a spacing of 1 cm, bending to the maximum curvature +2.5 cm ⁻¹ , , Measured by bending back to the maximum curvature of -2.5 cm ^{-1 and} then back. The bending stiffness (B) [ N · cm ² / cm] was calculated from the inclination when the inclination of the bending moment with respect to the curvature became substantially constant after bending to the front side. Further, the bending recovery property (2HB) [ N · cm / cm] was obtained from the hysteresis width. The larger the B value, the harder the bending and the higher the tendencies. The larger the 2HB value, the worse the bend return property and the lower the stiffness.

(Sensory evaluation of elasticity and stiffness)
As a texture evaluation of the elasticity when touching the fabric with a hand, the cotton broad was evaluated as 5 levels with a maximum rank of 5 and a minimum rank of 1. Judgment was made by one skilled in the hand.

(Sense of sheer)
It evaluated using the Boken standard BQE A038 see-through prevention test of the Boken quality evaluation organization. A white plate is placed on the skin side of the test piece, and the reflectance (RS-white) of visible light (380 nm to 780 nm) on the outer surface is measured. Similarly, the black plates are overlapped, the reflectance (Rs-black) is measured, and the see-through prevention degree is calculated. If the degree of sheer prevention is 74 or more, it can be used as a dress shirt without worrying about the sheer feeling. Degree of see-through = Rs-black / Rs-white × 100

(W & W property of knitted fabric)
The shape stability (W & W property) of the dress shirt was evaluated according to the quality performance measures council law for apparel products. The determination was performed using a determination standard three-dimensional replica defined in AATCC 124-1984. Judgment was displayed from the fifth grade (good) to the first grade (bad).

(Product shape retention)
Using the pleated property test method for knitted fabrics of JIS-L1060: 2012, the three-dimensional effect of the shape of the pleat after washing was used as a substitute evaluation for shape retention. The grade was determined according to the criteria for the pleated shape before washing and the pleated shape after repeating the washing operation and the drying operation 5 times. As a pleat determination standard, a five-level determination standard three-dimensional replica defined in AATCC Test Method 88C was used. Judgment was displayed from the fifth grade (good) to the first grade (bad).

(Ease of movement of the upper body when wearing a dress shirt)
After sewing the fabric into a long-sleeved dress shirt with neck length 41 and sleeve length 84, a middle-aged 30-year-old man wears it, spreads both hands horizontally, and turns both hands / shoulders horizontally around the spine. Using the ease of movement (resistance of the fabric to movement) as a sensory value, a three-step evaluation was performed in the order of easy movement: ○>Δ> ×: difficult to move.

Example 1
