等がある。2. Description of the Related Art Conventionally, many bulky yarns having a spun appearance and texture using synthetic fibers have been proposed. Above all, emphasis has been placed on how to express the bulge (bulkyness) characteristic of worsted tone with synthetic fibers, and various methods have been tried. For example, a method of imparting swelling by utilizing a difference in contraction of the original yarn characteristics, a method of simultaneously false-twisting yarns of different elongation to form a two-layer structure processed yarn, or a method of effectively reducing the yarn length difference by a fluid disturbance treatment There is a method of utilizing a core / sheath type bulky yarn.

Difficult to express effective bulge. In addition, the two-layer structured yarn obtained by simultaneously false-twisting different elongation yarns has a stronger sense of flapping than a swelling feeling, and a streak defect (hasiri) peculiar to the two-layer structure in the fabric.
It is easy to come out. Further, the core / sheath type bulky yarn obtained by the fluid disturbance treatment can provide a span-like feel due to the loop fluff on the yarn surface and can impart bulkiness peculiar to Taslan processing, so that it is effective from both appearance and texture. On the other hand, there is a drawback that the unwinding property from the winding package and the knitting and weaving properties are reduced due to the entanglement of the loops and the tarmi.

Japanese Patent Application Publication No. 99637 describes a multi-layer structured yarn having a three-layer structure. However, since this processed yarn is a yarn obtained by subjecting three types of yarns having different physical properties (elongation difference) to core / sheath taslan processing and then false twisting,
The confounding property of the entire yarn is reduced, and a deviation due to a difference in yarn length occurs due to a tension, a squeezing force, and the like received in a subsequent process, and a hair clump-shaped defect is likely to occur. In addition, since the loop fluff composed of the filament of the outer layer part having high elongation is in a free state, it is easily stretched by the twisting action at the time of false twisting and becomes an excessive loop fluff, and the unwinding property and knitting and weaving property in the subsequent process. Is reduced.

% Or more, preferably 50% to 120%. In the simultaneous false twisting of different elongation yarns, the difference in elongation is restricted by the difference in elongation and the number of false twists. It is important to use elongation yarns. If the elongation difference is less than 40%, the yarn length difference is so small that a two-layer structure yarn cannot be obtained. Further, the elongation of the supply multifilament yarn 1 is preferably 70% to 150%, and the elongation of the supply multifilament yarn 2 is preferably 30% to 100%.

It is necessary that √D <T <25000 / √D.
If the number of false twists is less than the above range, even if there is a difference in elongation of 40% or more, a sufficient twist difference cannot be provided due to a small twisting action. Further, in the number of false twists above the range,
Yarn breakage is likely to occur, and furthermore, the yarn length difference becomes too large, and the winding around the core yarn is too strong, resulting in a tight yarn form. Become. In the present invention, by setting the number of false twists in the above range, it becomes possible to impart a crimp and to develop a yarn length difference required for a two-layer structure,
The composite yarn A is suitable for improving the entanglement by the subsequent fluid disturbance treatment and obtaining a bulky multilayer composite yarn. Further, the number of false twists of the composite yarn A is within the range of the above expression, and the yarn length difference is 5 to 20.

となる。Next, the composite yarn A provided with the crimp and the yarn length difference and another non-torque multifilament yarn B are aligned and subjected to a fluid disturbance treatment to produce a multilayer composite bulky yarn. As a condition of the fluid disturbance treatment, it is necessary to make the oversupply rate of the composite yarn A larger than the oversupply rate of the non-torque multifilament yarn B. That is, preferably, the oversupply rate of the composite yarn A is 6 to 50%, the oversupply rate of the non-torque multifilament yarn B is 1 to 20%, and the difference is 5 to 30%. By performing a core and effect processing in which the composite yarn A is on the sheath side and the non-torque multifilament yarn B is on the core side, the non-torque multifilament yarn B is the core, and the multifilament yarn of the composite yarn A has a small elongation. 2 is a middle layer portion, and the multifilament yarn 1 having high elongation has a three-layered yarn form arranged in an outer layer portion.

m, weaving into a twill structure with a weft density of 50 threads / 2.54 cm, and dyed in different colors with a disperse dye, an acid dye and a cationic dye, respectively. The resulting fabric had an appropriate fluffiness and slimy feeling, exhibited a worsted texture with excellent swelling, and a multicolor heather-like product was obtained with three different colors. Table 1 shows the production conditions in the examples and the characteristic values of the obtained yarns.

ことが可能となる。According to the present invention, the multilayer composite bulky yarn obtained by the present invention has an unwinding property due to a synergistic effect of its yarn form (multi-fiber entangled yarn having a multilayer structure) and yarn characteristics (yarn length difference, crimpability). It is excellent in knitting and weaving properties, and can impart span-like fluffiness and swelling to a fabric obtained by knitting and weaving. In addition, by skillfully combining the characteristics of the multifilament yarns used, it is possible to impart a wide variety of characteristics such as a multi-layer structure yarn of four or more layers or a multicolor heat effect, and it is possible to produce elegant yarns. Become.
