に関するものである。[Detailed description of the invention] The present invention relates to a weft knitted fabric that has an appropriate smooth feel and appropriate gloss, has no bends in the knitting rows in the wale direction (warp direction), and has high elasticity in the warp direction. .

従来の緯編地は、第１図に示すごとく、編糸は
一定の撚方向の撚糸のみを使用するか、通常の撚
係数のＳ撚糸とＺ撚糸とを交互に使用したもので

た。 As shown in Figure 1, conventional weft knitted fabrics use only twisted yarns with a fixed twist direction, or alternately use S-twisted yarns and Z-twisted yarns with a normal twist coefficient, and have a wale pattern. The knitting yarn in the direction was relatively straight, and the elasticity in the warp direction was small.

糸は一般的に強撚糸が使用されているが、同じ撚

ち斜向が発生しやすい傾向にあつた。 In addition, highly twisted yarns are generally used as spun yarns for knitted fabrics that require a smooth feel, but when single yarns with the same twist direction are used, untwisting torque is large, so the knitting rows in the wale direction are There was a tendency for bending, that is, skewing, to occur.

になつてきている。 If you use highly twisted twin yarns that are made by first twisting a strongly twisted ply yarn and twisting it in the opposite direction to the first twisting direction, the untwisting torque is small, so you can create a knitted fabric with a crisp feel without diagonal twisting. Although it is possible to make such fabrics, the stretchability in the warp direction is as small as that of conventional knitted fabrics.
In addition, with the recent diversification of tastes, knitted fabrics with a moderately smooth feel and a moderate luster are now required.

本考案は、これらの問題に対処するものであつ

するにある。 The present invention addresses these problems, and aims to provide a moderately smooth feel and a moderate gloss, without unevenness due to diagonal knitting, and with elasticity in the warp direction. is to provide large weft knitted fabrics.

S-twist twin yarns are combined and twisted in the S-twist direction at a twist coefficient of 10.0, and Z-twisted yarns are combined and twisted in the Z-twist direction at a twist coefficient of 5.0 to 10.0, and spun yarns with a twist coefficient of 2.5 to 5.0 and different twist directions are combined and twisted in the Z twist direction. The gist of the invention is a weft knitted fabric formed by knitting twisted twin yarns alternately arranged in at least one course.

編成されている。 The above-mentioned S-twist double yarn and Z-twist double yarn are as follows, for example. First, the S-twist twin yarn has a twist coefficient of 2.5.
~5.0 and the twist coefficient is almost the same S
5.0~ by aligning twisted spun yarn and Z-twisted spun yarn
It is twisted in the S twist direction with a constant twist coefficient within the range of 10.0. Further, the Z-twist double yarn is obtained by aligning spun yarns similar to those described above and twisting them together in the Z-twist direction with substantially the same twist coefficient as the S-twist double yarn. As shown in FIGS. 3A and 3B, these double yarns have a portion _T1 where additional twist of the spun yarn is emphasized and a portion _T2 where the fibers have good parallelism. In Figure 2, a, b,
c, d, e are knitting yarns, 1, 1', 2, 2', 3,
3' indicates the stitch, ,, is the same as the needle row, indicates the wale direction, and A and B indicate the course direction. Here, the knitting yarns a, c, and e are Z-twist double yarns, and the knitting yarns b and d are S-twist double yarns. A stitch is formed and S
The 1st, 2nd, and 3rd stitches of course B are formed with knitting yarn b of twisted double yarn. Since each knitting yarn is a strongly twisted yarn, due to the influence of untwisting torque, stitch 1 is tilted to the left and stitch 1' is tilted to the right, so that they are knitted in a "dog-dog" shape.

本考案の編地が経方向に大きな伸縮性を示すの

戻つて“くの字”形になるものである。 The reason why the knitted fabric of the present invention exhibits great elasticity in the warp direction is that when tension is applied to the knitted fabric shown in Figure 2 in the vertical direction, that is, in the wale direction, for example, stitches 1 and 1' This is because the "dog-shaped" shape thus formed becomes substantially straight in the wale direction. Therefore, when the tension is released, it returns to its original shape and assumes a dogleg shape.

本考案においては、撚係数が2.5〜5.0の紡績糸

ールが発生し易くなる。 In this invention, it is necessary to use a spun yarn with a twist coefficient of 2.5 to 5.0. If the twist coefficient is less than 2.5, the strength will not be sufficient and the spun yarn itself will not have elasticity. On the other hand, if it exceeds 5.0, it will not be strong enough. decreases, and snarls are more likely to occur.

にあり、さらにシヤリ感も低下する。 The important point in this invention is that two spun yarns with different twist directions are combined and twisted in the S twist direction, and the Z
The method is to alternately use yarns that are twisted together in the twisting direction for at least one course. When the above-mentioned two spun yarns with different twist directions, that is, the S-twist spun yarn and the Z-twist spun yarn, are aligned and twisted in the S-twist direction to form a double yarn, the S-twist spinning that makes up the double yarn The yarn gives it a smooth feel and elasticity, and the other Z-twist spun yarn has good parallelism of fibers, giving it luster. In the case of double yarns, if the twist direction of the spun yarns constituting the double yarns is the same as the twist direction of the combined twist, that is, the twist direction of the first twist is the same as the twist direction of the first twist, the elasticity in the warp direction is improved. Although it is possible to obtain a knitted fabric that has a high degree of elasticity and is rich in smoothness, the high twist tends to reduce gloss and lower the quality of the knitted fabric. Furthermore, when the twisting direction of the first twist and the twisting direction of the first twist are opposite to each other, elasticity in the warp direction can be obtained, but the recovery rate tends to be slightly lowered, and the crisp feeling is also lowered.

実質的に同じであることが好ましい。 Further, in the present invention, the twist coefficient of the combined twist of the two spun yarns, that is, the twist coefficient of the final twist, is 5.0 to 10.0, preferably 6.5 to 8.5. If the twist coefficient of the ply twist is less than 5.0, the texture will be poor, and one of the spun yarns constituting the double yarn will become loosely twisted, which will cause fuzz in the knitted fabric and deteriorate the appearance of the knitted fabric. . On the other hand, if the twist coefficient of the ply twist exceeds 10.0, too much twist is applied to one of the spun yarns constituting the double yarn, and the other spun yarn becomes lumpy, which increases the smoothness but reduces the luster. Irregularities appear on the surface of the fabric, deteriorating the appearance and quality of the knitted fabric, and variations in thread tension also occur during knitting, which tends to cause trouble. In this invention, S-twist twin yarn and Z
It is preferable that the twist coefficients of the twisted twin yarns, that is, the twist coefficients of the two twisted yarns, are substantially the same.

る。 In the present invention, by alternately knitting the S-twisted yarn and the Z-twisted yarn into two or more courses, a knitted fabric with a weft border-like appearance can be obtained. In addition, by using yarn dyed yarn, a knitted fabric with further surface changes can be obtained.

向の編目の列は斜向することがないものである。 In the case of the present invention, a double yarn is used, which is made by combining spun yarns with different twist directions in a constant twist direction.
It has a moderate luster and a moderate smooth feel, and since it is knitted by alternating the S-twist twin yarn and the Z-twist twin yarn as described above, the stitches are diagonal to the left and diagonal to the right. The stitches form a dogleg shape on the knitted fabric, exhibiting great stretchability in the warp direction, and the rows of stitches in the warp direction do not run diagonally.
