<Industrial Application Field> The present invention relates to a highly twisted yarn with a modified cross section suitable for textured knitted fabrics. <Prior Art> Generally, woven and knitted fabrics using highly twisted yarns have a unique texture and appearance, and are therefore used in a wide range of fields, including Japanese and Western clothing. For this reason, strongly twisted yarns made of various thermoplastic filaments have been proposed in the past, and the single fibers have round or triangular cross-sections. <Problems to be solved by the invention> However, highly twisted yarns using single fibers with these cross-sectional shapes cannot be tensioned or
It has a firm, crisp feel and has a textured effect when applied with torque, but as shown in Figure 3, the thread surface is smooth, giving it a metallic luster, and the contact area with the hand is large, so it has a dry surface. It had the disadvantage of being scarce. In addition, as the market becomes more flexible, there is a desire to make highly twisted yarns made of thermoplastic filaments more similar to the appearance and texture of strongly twisted silk fibers, and to improve the appearance and texture of highly twisted yarns made of thermoplastic filaments. Improvements in gloss and surface texture were desired. The present invention was developed in response to the above-mentioned needs, and its purpose is to provide a woven or knitted fabric that has a luster similar to that of silk fibers, has a tension on the resulting woven or knitted fabric, and has a waist and a natural smooth feel. To provide a highly twisted yarn with a modified cross section that can give a texture close to that of highly twisted silk yarn rich in dry surface touch. <Means for solving the problem> That is, the present invention is a thermoplastic deformed fiber whose cross-sectional shape is a mushroom shape consisting of a triangular umbrella and a trunk, and which satisfies the following formulas () and (). cross-section multifilament yarn

[Formula] (D is the denier of the multifilament yarn) Twist number T (t/m)
50% or more of the single fibers forming the outer periphery of the multifilament yarn are arranged such that the sides of the umbrella and trunk are located in the outermost layer. It is a strongly twisted yarn. H≧K 1 () K 1 ≧2K 2 () where H: Distance from the top of the umbrella to the bottom of the trunk K 1 ; Maximum width of the umbrella K 2 ; Maximum width of the trunk The present invention will be explained in more detail below. . First, the highly twisted yarn with an irregular cross section of the present invention has a mushroom-shaped cross-sectional shape consisting of a triangular cap and a trunk, and the distance from the top of the cap to the bottom of the trunk is H, and the maximum width of the cap is K. 1. When the maximum width of the executive is K 2 ,
These are composed of thermoplastic multifilament yarns with irregular cross sections that satisfy the following formulas () and (). H≧K 1 () K 1 ≧2K 2 () In other words, the multifilament yarn of the present invention has a triangular cross-sectional shape as shown in FIG. It has a mushroom shape consisting of a substantially rectangular trunk 2 protruding from the center of the umbrella 1, and the maximum width K1 of the umbrella part 1 is the trunk 2.
is larger than the maximum width K 2 of the umbrella section 1, and the distance H from the upper end of the umbrella section 1 to the lower end of the trunk section 2 is the maximum width K 1 of the umbrella section 1.
Since the single fibers on the outer periphery are larger, the length direction of the cross section of the single fibers on the outer periphery is bent along the circumferential direction by the twisting yarn, and as will be described later, more than 50% of the number of single fibers on the outer periphery is The corner portion 4 on the outer layer side can be arranged so that the side surface is located on the outermost layer and protrude outward from the trunk 2. Moreover, the maximum width of umbrella part 1 is K 1
is more than twice the maximum width K2 of the trunk 2, so that a sufficient protrusion length of the umbrella part 1 protruding from the trunk 2 on the outer layer side of the yarn can be ensured, and the dry surface touch due to the unevenness of the yarn can be improved. Can be done. Note that the distance from the top of the umbrella part 1 to the base 3 is H 1 , and the distance from the top of the umbrella part 1 to the bottom 3 is H 1 .
When the distance from to the bottom of executive 2 is H 2 ,
If 0.6H 1 ≦H 2 , the dry surface touch can be further improved. In this case, if the maximum width K 1 of the umbrella section 1 is less than twice the maximum width K 2 of the umbrella section 2, the protrusion length of the umbrella section 1 protruding from the outer layer side of the yarn is insufficient, and the umbrella section 1 If the distance H from the upper end to the lower end of the trunk 2 is less than the maximum width K1 of the umbrella portion 1 , the width direction of the cross section will be bent in the circumferential direction of the yarn due to the twisted yarn, and both will have a dry surface. This is not preferable because the touch becomes poor. In addition, in the highly twisted yarn with a modified cross section of the present invention, the thermoplastic multifilament yarn with a modified cross section has a twist number T (t/m).

If it is less than [Formula], the increase in convergence, rigidity, torque, etc. due to twisting will be small, and the above-mentioned effects will be poorly expressed, so it is not preferable. Furthermore, the irregular cross-section strongly twisted yarn of the present invention is one in which 50% or more of the number of single fibers forming the outer circumference of the thermoplastic irregular cross-section multifilament yarn is arranged such that the sides of the umbrella part and trunk are located in the outermost layer. It is.
That is, as shown in Fig. 1, in the highly twisted yarn of the present invention, more than 50% of the single fibers forming the outer periphery of the highly twisted yarn are arranged such that the side surfaces of the umbrella part 1 and trunk part 2 are located in the outermost layer. The outermost layer of the highly twisted yarn is uneven due to the protrusion of the corner portion 4 on the outer layer side of the umbrella portion 1.
In this way, in the highly twisted yarn of the present invention, more than 50% of the single fibers forming the outer periphery are arranged so that the side surfaces of the umbrella part 1 and the trunk 2 are located in the outermost layer, so the outermost layer of the highly twisted yarn is square. The protruding portions 4 create unevenness, and when a woven or knitted fabric is used, the protruding corner portions 4 will pleasantly stimulate the fingertips when the fabric is touched, and the contact area transmitted to the fingertips will also be reduced, resulting in a smooth texture. It has a silky smooth and dry surface. In this case, at least 50% or more preferably 70% or more of the single fibers forming the outer periphery of the yarn must be arranged so that the sides of the umbrella part 1 and trunk 2 are located in the outer layer. , this number of single fibers is
If it is less than 50%, the number of protrusions of the corner portions 4 will decrease and the dry surface touch will deteriorate, which is not preferable. The highly twisted yarn of the present invention has an increased stiffness due to the unevenness of the outer layer of the yarn and strong twisting, which improves the tension and stiffness, giving it a texture similar to highly twisted silk yarn. In addition, as mentioned above, the outer layer of the highly twisted yarn is uneven due to the protrusion of the corner portions 4, so the convex portions (corner portions)
The light rays reflected from the concave portion (trunk) partially cancel each other out, creating a silk-like soft luster. In addition, as shown in FIG. 1, if the corners 4 on the outer layer side of the monofilament umbrella 1 forming the outer periphery of the highly twisted yarn are arranged so as to protrude randomly in the left winding direction A and the right winding direction B, the texture will be improved. It can provide a natural smooth feeling without any directionality. The thermoplastic multifilament yarn of irregular cross-section in the present invention can be obtained by spinning using a special spinneret in which the slit width, length, and shape of the spinning holes are appropriately changed.
The method proposed in No. 20336 is applied. As the thermoplastic multifilament yarn in the highly twisted yarn of the present invention, multifilament yarns obtained from polymers such as polyester and polyamide, and copolymers and blended polymers thereof are used. In order to obtain such gloss and texture, polyester multifilament yarn with excellent physical properties is preferred. <Examples> Hereinafter, the present invention will be specifically explained using examples. Example Polyester irregular cross-section multifilament yarn in which the cross-sectional shape of the single fibers is mushroom-shaped as shown in Fig. 2 and H/K 1 = 1.45, K 1 /K 2 = 3.1, H 2 /H 1 = 1.1.
The number of twists of 75d/48f is 1730 (t/
m), and then subjected to steam setting at 80° C. for 45 minutes to obtain S-twist and Z-twist highly twisted yarns with irregular cross sections of the present invention. When the cross-section of the obtained highly twisted yarn was photographed with a magnification of 400 times, as shown in Figure 1, 12 (75%) of the 16 single fibers forming the outer periphery of the yarn were located in the umbrella and trunk portions. The side surface was located at the outermost layer, and the outer corners of the umbrella of 12 single fibers protruded randomly from the outer periphery of the yarn in both the right and left winding directions. Two of these strongly twisted S-twisted yarns and two Z-twisted yarns are used alternately for the warp and weft yarns, and the warp density is 86 yarns/inch.
Plain weave is woven with a weft density of 85 threads/inch, and the resulting gray fabric is relaxed and scoured in accordance with conventional methods, then subjected to graining treatment in hot water at 100°C for 30 minutes, then dyed and finished to create a jersey. I made crepe fabric. This fabric has a uniform grain and is stretched,
It had excellent elasticity and a natural dry feel, the surface was silky and dry to the touch, and it had a silky soft luster. <Effects of the invention> The highly twisted yarn with an irregular cross section of the present invention is a mushroom-shaped thermoplastic multifilament yarn with an irregular cross section consisting of a triangular umbrella section and a trunk of single fibers with a twist number T (t/m).

In addition, the single fibers of the multifilament yarn to be twisted are the above (),
Formula () is satisfied, and more than 50% of the single fibers forming the outer periphery of the highly twisted yarn are arranged so that the sides of the umbrella part and trunk are located in the outermost layer, so the outer layer of the highly twisted yarn is the umbrella. It has unevenness due to the protruding corners on the side, and when you touch the resulting fabric, your fingertips are pleasantly stimulated by the protruding corners, and the contact area transmitted to your fingertips is also reduced, so it feels like silk to the touch. It has a smooth and dry surface touch. Furthermore, the unevenness of the outer layer of the highly twisted yarn and the increased rigidity due to the highly twisted yarn combine to improve the tension, stiffness, and smooth feel, giving the yarn a texture similar to that of highly twisted silk yarn. Furthermore, as mentioned above, the outer layer of the highly twisted yarn has irregularities due to the protruding corners, so the light rays reflected by the concave and convex parts partially cancel each other out, giving it a silk-like soft luster. .
