[Detailed explanation of the idea]

B. Technical Field of the Present Invention The present invention relates to a single knitted fabric having an uneven appearance.More specifically, the present invention relates to a single knitted fabric having an uneven appearance. This invention relates to a knitted fabric suitable for sports clothing, underwear, etc., which has excellent horizontal and elastic properties and has heat retention properties. B. Prior art and its problems Conventionally, many knitted fabrics having surface changes on both the front and back sides have been provided, but most of them are knitted on both sides. However, these double-sided knitted fabrics have problems in thinning and stretchability, and also have low productivity and cost problems. In addition, some single knitted fabrics with surface changes include those produced by the tuck method and those produced by a special machine for fleece. However, when a special knitting machine is required, the knitting machine is expensive and the surface change is poor. In any case, the knitted fabrics with surface changes that have been conventionally provided have the disadvantages of low productivity, cost problems, and lack of stretchability. Looking at the current market, products are diversifying and becoming more fashionable, and there is a demand for fabrics that have surface changes in their appearance, as well as fabrics that are superior in terms of functionality. C. Purpose of the present invention The knitted fabric of the present invention can be used without using a special machine (m/c), on a single knitting machine that is a general-purpose m/c and has extremely high productivity. This provides a knitted fabric with excellent functionality such as stretchability. D. Structure of the present invention The structure of ^the present invention ^{is as follows} :
... (hereinafter each yarn B ¹ , B ² , ... is referred to as yarn B), in a single knitted fabric consisting of two types, yarn A ¹
and A ² forms a knit loop and a tuck loop with one or several consecutive stitches, and at least one wale or more is welted between the knit loop and the tuck loop, and yarn B forms a tuck loop in the wale tacked by yarn A ¹ . In knitted and welted wales, a plurality of consecutive courses are formed in a knitted loop, and the threads are formed in continuous courses in the knitting direction.
A ² forms a tuck loop in a wale knitted with yarn A ¹ and a knitted loop in a tacked wale, while yarn B forms a tuck loop in a wale knitted with yarn A ² , and a tuck loop in a knitted and welted wale. By forming a knit loop and continuously forming a plurality of courses, the tack loop of yarn B, which is continuous with the tack loop of yarn A ¹ , is connected to the knit loop of yarn A ² .
The tack loop of yarn B, which is continuous with the tack loop of A ² , is held in the knit loop of yarn A ¹ , so that each sinker loop between the knit loop and the tatsu loop, which have welted one or more wells of yarn A 1 and yarn A ^{2 ,} becomes a sinker. A single knitted fabric with an uneven appearance characterized by a geometric linear arrangement on the loop side. ”. In the present invention, various yarns constituting the knitted fabric can be used, such as synthetic fiber raw silk, processed yarn, spun yarn, natural fiber filament yarn, spun yarn, and mutually composite yarn. The synthetic fiber used in the present invention may be any of polyester, polyamide, polyacrylonitrile, polypropylene, etc., but preferably twisted yarn is preferable. In the present invention, the yarns B ¹ , B ² , ... are made of cotton,
Hydrophilic fibers such as wool or mixed yarns containing hydrophilic fibers are used to mainly constitute the surface of the knitted fabric, that is, the needle loop side, and yarns A ¹ and A ² are temporarily twisted with hydrophobic fibers. It is knitted using yarn, mainly forming the back side of the knitted fabric, that is, the sinker loop side. Of course, hydrophobic fibers such as synthetic fibers may be used for the yarns B ¹ , B ^{2 , etc.} , and hydrophilic fibers may be used for the yarns ^{A 1 ,} A ² . Article A ¹ ,
Hydrophobic fibers such as synthetic fibers can be used for each of ^A2 , and the type can be selected depending on the intended use of the resulting knitted fabric. Furthermore, the loop lengths of the yarns A ¹ , A ² and the yarns B ¹ , B ² , etc. are not particularly limited, but when the knitted fabric is composed of different types of yarns, it is preferable that the loop lengths of the yarns A 1 , A 2 and the yarns B ¹ , B ^{2 ,} etc. It is recommended that the loop length of the yarns B ¹ , B ² , ... be 2/3 or less, preferably 1/2 or less of the loop length of the yarns B 1 , B 2 , etc.
The knit loops A ¹ and A ² are knitted into the inner layer of the knitted fabric, and although it has a single structure, it is possible to obtain a seemingly reversible knitted fabric. In the present invention, yarns A ¹ and A ² constituting the knitted fabric
Although the apparent fineness of the yarns B ¹ , B ² , ... is not particularly limited, it is desirable that the apparent fineness of the yarns A ¹ , A ² be the same as the apparent fineness of the yarns B ¹ , B ² , B ³ , ... By setting the fineness to 1.5 times or more, the linear form of the yarns A ¹ and A ² becomes clearer, and the knitted fabric has an extremely higher apparent thickness than a normal single knitted fabric. Furthermore, by making several knit loops and tuck loops of the yarns A ¹ and A ² in succession, and by making multiple wales and welts between the knit loops and the tatsu loops, the yarn B between the yarns A ¹ and A ² , that is, B ¹ , B ² ,
By increasing or decreasing the number of courses, the length of the sinker loop between the knitted loop and the tacked loop and the linearly arranged geometric pattern can be easily changed. Depending on the knit and tuck positions of ¹ and ^A2 , the knitted fabric has a twill-like or stripe-like appearance with surface changes on both the needle loop side and the sinker loop side. A basic example of the present invention will be explained in detail below with reference to the drawings. Fig. 1 is a tissue diagram showing an example of a ^single knitted fabric having an uneven appearance according to the present invention. The yarn knitted into
B ¹ , B ² , and B ³ are used to tack only the wales that have become tacked loops b at the yarn feeder 1, and are knitted for knitted and welted wales. Yarn A ² fed at yarn feeder 5 is applied to every other cylinder needle in the same wale as yarn feeder 1, and in the wale that became knit loop a at yarn feeder 1, a tatsu loop b' is formed, and in the wale that became tatsu loop b at yarn feeder 1, it is formed as a knit loop.
a' is knitted alternately, and the yarns B ⁴ , B ⁵ , B 6 fed through yarn feeders 6, 7, ^{and 8} are tucked into loops at yarn feeder 5.
Only wales that have become b' will be tacked, and knitted and welted wales will be knitted. That is, according to the present invention, the stitch structure of the knitted fabric knitted with the structure shown in FIG. 1 is shown in FIG. 5 as seen from the needle loop side, and the stitch structure as seen from the sinker loop side is shown in FIG. When each yarn supplied from yarns 1, 2, 3, and 4 is tacked with the same needle, and the tacked loop is held in knit loop a' of yarn ^A2 supplied from yarn feeder 5, Since the supplied yarn A ¹ is knitted every other stitch, the sinker loop between the knit loop a and the tuck loop b of the yarn A ¹ moves back and forth in a zigzag pattern between the respective knit loops a and a'. Become. Yarn A ² fed from yarn feeder 5 in the same way
The sinker loop between the knit loop a' and the tack loop b' moves back and forth in a zigzag pattern between the respective knit loops a' and a, and the sinker loop of the yarn fed from the yarn feeder 1 and yarn feeder 5 As shown in Figure 2, it is possible to obtain a single knitted fabric having an uneven appearance with a "diamond" shape and rich surface variations. E Effects of the present invention A yarn A ¹ that becomes a floating yarn on the sinker loop side of the knitted fabric,
By arranging the sinker loops of ^A2 diagonally to the course direction, it has good elasticity both vertically and horizontally, and has good heat retention with an air layer with the lowest thermal conductivity between the floating yarns. You can get land. The yarn used is the surface of the knitted fabric, that is, the yarn.
For B ¹ , B ² , ..., use synthetic fiber tentatively twisted yarns that are hydrophobic fibers, and for the back of the knitted fabric, that is, threads A ¹ , A ² , use hydrophilic fibers or mixed yarns containing hydrophilic fibers. As a result, it has excellent durability and good sweat absorption during the early stages of perspiration, making it a knitted fabric suitable for underwear and the like that does not require a large amount of sweat absorption. In addition, hydrophilic fibers or mixed yarns containing hydrophilic fibers are used on the front surface of the knitted fabric, that is, yarns B ¹ , B ² , and so on, and tentative twists of synthetic fibers that are hydrophobic fibers are used on the back side of the knitted fabric, that is, yarns A ¹ and A ² . By using processed yarn, there is no backflow of sweat, and the feeling of cold and stickiness after sweat absorption is extremely low, making it a knitted fabric that is especially suitable for sports clothing such as shirts that require a large amount of sweat absorption. Become. Furthermore, by using tentatively twisted synthetic fiber yarns, which are hydrophobic fibers, for both the front and back sides of the knitted fabric, that is, yarns A ¹ , A ² , yarns B ¹ , B ² , etc., durability,
A knitted fabric with good color fastness, excellent wash and wear properties, and quick drying properties can be obtained. By setting the apparent fineness of the yarns A ¹ and A ² that become floating yarns on the sinker loop side of the knitted fabric of the present invention to be at least 1.5 times the apparent fineness of the yarns B ¹ , B ² , ... The geometric pattern arranged becomes clearer, and the knitted fabric has a much higher apparent thickness than a normal single knitted fabric. Also, yarns A ¹ , A ² and yarns B ¹ , B ² , B ³ , which become floating yarns,
... is composed of different types of yarns, the loop length of yarns A ¹ , A ² is 2/3 of the loop length of yarns B ¹ , B ² , B ³ , ...
By reducing the thickness to 1/2 or less, it is possible to obtain a seemingly reversible knitted fabric. Furthermore, by changing the knitting and tuck positions of the yarns A ¹ and A ² that become the floats, it is possible to easily change the length of the floats and the geometric pattern created by the floats, and as a result, the surface changes. A knitted fabric with rich functionality can be obtained. The present invention will be explained below with reference to examples. In the examples, the apparent fabric thickness refers to the thickness measured by placing one sample on the sample stand of the thickness measuring device and placing it on a 2 cm ² presser foot.
The thickness was measured at five locations after 10 seconds of applying a load of 7 g/cm ² and was expressed as the average value. Example 1 Using a 32G single knitting machine, yarn B ¹ ,
B ² , B ³ , B ⁴ , B ⁵ , B ⁶ are made of 100 denier polyester pre-twisted yarn, and threads A ¹ and A ² are 200 denier polyester pre-twisted yarn, with the same structure as shown in the figure. As a result of knitting, 200 denier polyester temporary twisted thread becomes a floating thread on the sinker loop side.
A knitted fabric was obtained in which A ¹ and A ² were given a surface change exhibiting a pattern as shown in FIG. 2, and which had excellent vertical and horizontal elasticity. Comparative Example 1 Using a 32G single knitting machine, 100 denier polyester pre-twisted yarn was used for threads F ¹ and F ² of the normal inlay structure in Figure 7, and 200 denier polyester pre-twisted yarn was used for threads E ¹ and E ² . As a result of knitting with the same structure as shown in the figure using twisted yarn, 200 denier polyester temporary twisted yarn becomes a floating yarn on the sinker loop side.
A knitted fabric was obtained in which E ¹ and E ² had a form as shown in FIG. However, compared to the knitted fabric obtained by the present invention, it had extremely little elasticity in the horizontal direction and little surface change. Example 2 Using a 28G single knitting machine, yarn D ¹ ,
150 denier polyester pre-twisted yarn was used for D ² , D ³ , D ⁴ , D ⁵ , D ⁶ , and 300 denier polyester pre-twisted yarn was used for yarns C ¹ and C ² , with the same structure as shown in the figure. As a result of knitting, 300 denier polyester temporary twisted thread becomes a floating thread on the sinker loop side.
C ¹ and C ² produced a knitted fabric with good surface change exhibiting a pattern as shown in FIG. 4, excellent vertical and horizontal elasticity, and high apparent fabric thickness. Comparative Examples 2, 3, Examples 3, 4, 5, 6 For comparison of apparent fabric thickness, ordinary single knitting machine
Jersey stitch with 28G, interlock with double knitting machine 28G, and yarns B ¹ , B ² , B ³ , shown in Fig. 1 according to the present invention,
B ⁴ , B ⁵ , and B ⁶ are knitted using 150 denier polyester pre-twisted threads, and yarns A ¹ and A ² are knitted using polyester pre-twisted threads with respective fineness ratios.
A knitted fabric was obtained by finishing under normal dyeing conditions. Using this knitted fabric as a sample, the apparent fabric thickness was measured and the results are shown in Table 1. As shown in Table ¹ , ^the apparent fineness of yarns A ¹ and A ² that become floating yarns on the sinker loop side, which is a component of the present invention ^, is Fineness of 1.5
By making it more than double, the knitted fabric has an apparent fabric thickness twice that of a jersey knitted fabric knitted under almost the same conditions, and almost the same as an interlock knitted fabric.

[Table] (Note) All threads used are processed polyester threads.
