2. Description of the Related Art Nowadays, there is a strong demand for diversification of materials in the field of garments, and the appearance of new differentiated materials having a more desirable appearance and tactile effect is not satisfied by the appearance and texture of conventional yarns. Is desired. As a material that meets these demands, for example, a yarn obtained by compositing crimped yarns and non-crimped yarns or compositing non-crimped yarns having different physical properties, etc. It is well known that it has properties that cannot be combined.
Various methods such as fluid treatment have been adopted.

Of these, the mainstream is the one having a core-sheath structure at the yarn stage (Japanese Patent Laid-Open No. 60-110941).
(See Japanese Patent Publication No. Sho 61-13009) and the like, in which the core-sheath structure is developed at the stage of the fabric by the heat treatment in the post-processing by utilizing the difference in thermal shrinkage between the constituent yarns.

[0005] In the latter case, a yarn that gives a core-sheath structure by giving a difference in yarn length at the stage of fabric by utilizing the difference in heat shrinkage has a shrinking action by restraining the texture points of the woven fabric or the loop connection points of the knitted fabric. As a result, there is a problem that the desired bulkiness and spun-like property cannot be obtained because a sufficient difference in yarn length does not occur, and the constituent yarns shrink due to heat, so that a hard feeling appears after dyeing and finishing. have.

It has the property of elongating by dry heat treatment, and its birefringence Δn is in the range of 0.01 to 0.12.
The areas with different birefringence are randomly distributed in the surrounding area, and multiple single filaments intermittently form crimped parts and non-crimped parts alternately in the longitudinal direction. The gist of the present invention is a composite mixed fiber, which is characterized in that A and B are intertwined with each other with substantially no difference in yarn length.

Among the yarns constituting the composite mixed yarn of the present invention, at least one is a yarn A having crimps, and the other at least one is a filament having different monofilaments in the longitudinal direction. The yarn B has a refractive index and is partially crimped, and there is no substantial difference in yarn length among all the multifilament yarns forming the yarn of the present invention. Figure 1
[FIG. 2] is a schematic view showing an embodiment of the composite mixed yarn of the present invention, in which a is a single filament of a yarn A having crimps,

On the surface of the composite mixed yarn of the present invention, there are almost no loop fluffs, slight voids and slack are formed between the single filaments, and the yarn having elasticity due to the crimping of the yarn A Article. Therefore, the unwindability from the package and the passability in the weaving / knitting process are good, and there is no problem in process passability.

Further, in the composite mixed yarn of the present invention, since at least one yarn A has crimp, it goes without saying that the fabric obtained by weaving and knitting can impart bulkiness and stretchability. That is, due to the synergistic effect of the crimped shape of the yarn A and the filament characteristics of the yarn B, which will be described later, it is possible to improve the swelling feeling of the worsted touch.

Next, in another yarn B constituting the composite mixed yarn of the present invention, portions having different birefringences are random in the longitudinal direction of each single filament in the range of birefringence Δn of 0.01 to 0.12. Therefore, the thermal treatment in the post-processing shows different thermal behavior in the minute portion along the longitudinal direction of each filament. The yarn B having such a microscopically non-uniform thermal behavior has a characteristic that it macroscopically expands when heat-treated at a high temperature. Although this elongation mechanism cannot be clearly explained, it is considered that the molecules are arranged in a bundle in the axial direction of the filament by heating at high temperature the filaments in which the molecular arrangement is randomly distributed in the longitudinal direction of the monofilament. . The filament group of the yarn B, which is entangled with the yarn A and has no difference in yarn length due to having the non-uniform elongation property due to the heat reception, is heated to generate a composite mixed yarn. At the same time as slack is generated in the longitudinal direction, a part of the monofilaments floats up on the outer periphery of the composite mixed yarn. When this elongation phenomenon is caused by a dyeing machine or setter in the dyeing finishing process, even if there are constraints such as the texture points of the woven fabric and the loop connection points of the knit,
Since the restraint as in the contraction action is not added, the elongation property is sufficiently expressed, and the fabric can be given a favorable bulging feeling and a hairy feeling.

As described above, the yarn B has the property of being elongated by heat treatment, but in order to make the swelling of the fabric and the feel of span adjustment preferable, dry heat treatment at 180 ° C. × 15 minutes is used for 3 times.
It is preferable to extend by at least%.

Further, one of the features of the present invention is that, in the plurality of single filaments constituting the yarn B, crimp portions and non-crimp portions are intermittently formed alternately in the longitudinal direction thereof. . The crimp portion is a mixture of irregular corrugated shapes, sawtooth shaped ones, or sine curve shaped ones, and does not have a constant shape. One size is the fiber axis. Most of the length of the crimp is 0.5 to 5 mm and the continuous crimp is 2 to 20 mm. Further, the non-crimp portion is a portion which is substantially linear or arched over 5 mm or more in the fiber axis direction, and the length thereof is 5 to 50 mm.

In the composite mixed yarn of the present invention, the yarn B in which the crimp portion and the non-crimp portion are formed at a relatively short pitch and the yarn A having crimps are substantially the yarn. Since the fibers are mixed and entangled without any difference in length, the entanglement between filaments is locally different. That is, the crimped portions of the yarn A and the yarn B have a relatively coarse entangled form, in which the filaments are likely to be detached and appear thick in appearance. On the other hand, in the non-crimp part, since the two crimps are entangled with each other relatively tightly, the integration between both yarns is strengthened, and the yarn becomes a converging part, which looks thin in appearance. It is considered that the reason for such a difference in the entanglement form is due to the difference in the openability due to the fluid disturbance. Moreover, since the non-uniform entangled portions are densely mixed, the flatness of the surface of the fabric obtained by weaving and knitting disappears, and a more preferable span tone feeling is exhibited.

As described above, in the composite mixed fiber of the present invention, it is necessary that the yarn A and the yarn B are mixed and entangled. If the yarns A and B are simply aligned, even if a difference in yarn length appears due to heat treatment, not only bulkiness but also local swelling and apparent thinness are not realized. In addition, since the focusing property is also poor, there is a problem in process passability.

The composite mixed yarn of the present invention is hard if it is dyed and finished by an ordinary method after being knitted or woven into a cloth by the synergistic effect of the fiber physical properties of the filaments forming the yarn and the yarn form. It is possible to obtain a warm bulge and a combed-like texture without denaturing, and it is a processed thread with good processability such as twisting and knitting.

EFFECTS OF THE INVENTION The composite mixed yarn of the present invention comprises a crimped yarn A and a birefringence Δ in the longitudinal direction of the single filament.
Since different parts of n are distributed in a specific range, and the yarn B in which the crimp portion and the non-crimp portion are alternately formed are intertwined with each other without having a yarn length difference, they are woven or knitted and woven. When heat treatment is applied at the stage, a non-uniform yarn length difference appears between the yarns A and B, and since the entangled form between the crimp part and the non-crimp part is different, a slight thick and thin feeling appears, so a warm wind It is possible to obtain a worsted-like cloth having a natural appearance in which the flatness of the surface and the flatness of the surface are erased.
