[Detailed Description of the Invention] (Field of Industrial Application) The present invention is capable of imparting to woven or knitted fabrics the appearance and texture of spun yarn, especially wool, such as bulge, sliminess, tension, waist, etc. The present invention relates to a composite structured yarn and its manufacturing method.

(Prior art) Conventionally, false-twisted crimped yarn obtained by false-twisting thermoplastic synthetic fiber filament yarn is extremely bulky in the condition of the yarn itself, that is, under minute tension close to zero tension. However, when this is made into a woven or knitted fabric, most of its bulkiness is lost.

In addition, two multifilament yarns with different elongations were used as a supply system, and they were aligned and subjected to false twisting, so that the high elongation multifilament yarn was placed in the outer layer and the low elongation multifilament yarn was placed in the inner layer. Two-layer crimped yarns are also known. Even if this crimped yarn is subjected to tension during weaving and knitting, most of the tension is applied to the core yarn and almost no tension is applied to the sheath yarn, so it is possible to form a fabric while maintaining bulk. It was an effective processed yarn for creating a fuller feel. However, when fabrics obtained from these yarns are heat-treated during the dyeing process, yarns with longer yarn lengths shrink more than yarns with shorter yarn lengths, reducing the difference in yarn length and causing a puffy or slimy feel. were not obtained, and improvements were desired. In addition, these yarns are squeezed out during the process due to the difference in length between the two yarns, and become pilled or fuzzed.

First, as shown in FIG. 1, the composite structure textured yarn of the present invention consists of a polyester multifilament false-twisted yarn (core yarn A) and a polyester multifilament false-twisted yarn having different physical properties from core yarn A. The fiber-spreading part 1 is formed of a sheath yarn B (sheath yarn B), and the sheath yarn B is spread while covering the core yarn A in the longitudinal direction of the yarn.

The core yarn A and the sheath yarn B have intertwined parts 2 alternately, and the sheath yarn B has loop fluff. The yarn length difference between the core yarn and the sheath yarn must be in the range of 1 to 10%. If the yarn length difference is 10% or less, no pilling will occur even under tension during the preparation process and weaving. There is no generation, and the weaving property is good. on the other hand,
If the yarn length difference exceeds 10%, the sheath yarns will shift when subjected to tension during weaving and pilling will occur in the longitudinal direction, resulting in fabrics with defects and the efficiency of weaving will be significantly reduced. descend. Furthermore, if the yarn length difference is less than 1%, the yarn will no longer be aligned in a composite structure consisting of core yarns and sheath yarns, and it will not be possible to impart a worsted texture to the fabric.

Next, the hot water shrinkage rate of the core yarn must be 1.5% or more higher than that of the sheath yarn. By setting the difference in hot water shrinkage to 1.5% or more, when the fabric is heat-treated in a dyeing process or the like, the yarn length difference is further promoted, the fullness of the fabric increases, and the worsted feel can be further emphasized. FIG. 2 shows the state of the composite structured yarn of the present invention shown in FIG. 1 after being subjected to hot water treatment.

It can be made into a fabric that is soft to the touch, has resilience, and has firmness and waist. On the other hand, if the Young's modulus of the core yarn is lower than that of the sheath yarn, the resulting woven or knitted fabric will lack tension and stiffness. In addition, by lowering the Young's modulus of the sheath yarn that forms the surface of the yarn, a soft feel can be obtained, and combined with the difference in yarn length, it becomes more fluffy, creating a worsted-like woven or knitted fabric with a slimy feel. I can do it.

When highly oriented polyester undrawn yarn is instantaneously hot-stretched under tension at a temperature above its melting point, the outer layer of the single filament that makes up the yarn exhibits a birefringence almost close to that of the drawn yarn, but the inner layer has a low birefringence, with a birefringence of 20X
If a highly oriented undrawn polyester yarn of 10-3 to 80X10-' is hot-stretched under the above conditions, a filament with a birefringence difference of at least 15X10-' between the inner and outer layers will be obtained. As a result, the filament becomes soft on the inside and hard on the outside, and although strong crimp can be obtained through friction false twisting in the subsequent drawing process, it exhibits a high Young's modulus.In general, when crimp is strengthened, Young's modulus tends to decrease. . ), it becomes a core thread that contributes to improving tension and waist. The difference in birefringence between the inner layer and the outer layer of a single filament, that is, the differential birefringence, is measured using the measuring method disclosed in Japanese Patent Application Laid-Open No. 48-35112.

For this reason, the composite structured yarn of the present invention can be manufactured even though the yarn length difference between the sheath yarn and the core yarn is kept within a range of 1 to 10%, which does not affect the passability of processes such as weaving, knitting, and weaving. If the fabric obtained by knitting or weaving is heat-treated, this yarn length difference will be expanded, and the fabric can be given fullness. Furthermore, the high Young's modulus of the core yarn makes it possible to impart tension and stiffness to the fabric.
