Abstract

PURPOSE:To provide a woven fabric imparted with slimy feeling. CONSTITUTION:The warp and/or weft of the objective woven fabric having special feeling are composed of a regenerated cellulose fiber, either the warp or the weft of the fabric is a multifilament yarn having a twist number of <=200T/m and the other is a spun yarn. Isolated protrusions formed by the entanglement of fibrillated fibers of the regenerated cellulose fiber are sporadically distributed on the surface of the woven fabric.

FIELD OF THE INVENTION The present invention relates to a fabric having a special texture.

[0002]

2. Description of the Related Art Woven fabrics using multifilament yarns as warp yarns and spun yarns as weft yarns are generally called Fujiet, and have gained popularity in the market due to their unique texture with a warm and spun touch and volume. However, due to recent consumer needs, those whose surface morphology has been further changed are required.

[0003] As one of them, it is required to further impart a moisturized slimy feeling, but generally, the slimy feeling is an ultrafine fiber of about 0.1 denier formed by a special thread such as sea-island fiber or split fiber. Although it can be applied by using and further raising treatment, it is low in productivity and high in cost because complicated and advanced techniques such as production and weaving of special yarn, and further fine-thinning process and raising process are required. belongs to.

Therefore, even in the above-mentioned Fujiet, the slimy feeling can be imparted similarly by using the ultrafine fibers, but the use of the ultrafine fibers causes a problem that the texture peculiar to the Fujiet is impaired. Further, as a matter of course, there are problems such as an increase in cost due to the use of ultrafine fibers and the complexity of lot management in production.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a woven fabric having a slimy feel without impairing the texture unique to Fujiet.

[0006]

That is, the present invention is a woven fabric in which the warp and / or the weft are composed of regenerated cellulose fibers, and one of the warp and the weft is 200 T / m.
A multifilament yarn having the following twist number, the other is a spun yarn, and island-shaped convex portions formed by entanglement of the fibrillated fibers of the regenerated cellulose fiber are scattered on the surface of the woven fabric. A woven fabric with a special texture, which is characterized by that.

The term "fibrillated fiber" as used herein means a microfiber obtained by breaking the side surface or the end portion of a single fiber of regenerated cellulose fiber and connecting at least one end to the single fiber. Say. Further, the island-shaped convex portion also refers to one formed by entwining a plurality of fibrillated fibers. Scattering means being distributed evenly on the surface of the woven fabric, the number of which is 100 to 10,000.
The number of particles / cm ² is preferable, and the area ratio is 5 to 60.
It is preferable to occupy%.

In the woven fabric having a special texture of the present invention, the warp and / or the weft of the woven fabric is composed of regenerated cellulose fibers such as Kyopra, viscose rayon, and polynosic rayon, and constitutes the surface of the woven fabric. It is preferred that regenerated cellulose fibers account for 30% or more of the fibers. For example, mixed with other fibers such as polyester fiber, mixed fiber, mixed twist, covering, etc. at the yarn stage,
Further, in the woven stage, other fibers are mixed to prepare warps, and other fibers are simultaneously mixed and weft-mixed.

In the present invention, the number of twists of the multifilament yarn must be 200 T / m or less, preferably 10
It is 0 T / m or less. Beyond this, the texture peculiar to Fujiet is lost. On the other hand, spun yarns include ordinary ring spun yarns, open-end spun yarns, direct-spun yarns by tow drafting, wrapping yarns obtained by wrapping a substantially untwisted short fiber bundle with yarns, and the direct spun yarns are preferred. The denier, fiber length, twisting coefficient, lapping coefficient, count, etc. of the single fiber may be appropriately selected, but the twisting coefficient is preferably about 50 to 120, and the lapping coefficient is preferably about 50 to 200.

The woven fabric with a special texture according to the present invention is not limited to one in which a multifilament yarn is used for one of the warp yarn or the weft yarn and a spun yarn is used for the other, and the spun yarn and the multifilament yarn are mixed in the other. And the ratio of the number of yarns of the multifilament yarn to the spun yarn on the other hand is 1: 6 to 6: 1.
Those described as are also preferable, more preferably 1: 4 to 4: 1, and particularly preferably 1: 2 to 2: 1. Those mixed in this way are preferable because a unique slimy feeling is imparted without impairing the texture unique to Fujiet. If the ratio of the number of mixed yarns is less than this, there is no great difference from that of the spun yarn alone, and if it exceeds this, the texture peculiar to FUJIET cannot be exhibited.

The structure of the woven fabric in the present invention is not particularly limited, but there are a flat structure, a twill structure, a satin structure and their modified structures, and a structure having a particularly large effect is the flat structure. The range in which the woven fabric density is highly effective is such that when the warp yarn denier is 50 to 150 d, the warp yarn density is preferably 70 to 250 yarns / inch, more preferably 80 to 160 yarns / inch, and the weft yarn denier is 50 to 20.
At 0 denier, the weft yarn density is preferably 50 to 100 yarns / inch, and more preferably 50 to 90 yarns / inch.

The method for forming the island-shaped convex portions of the woven fabric having a special texture of the present invention is, for example, in a wet state in a normal pressure washer, a continuous relaxing machine, a jet dyeing machine, an air flow dyeing machine or a wince dyeing machine. There are methods of rubbing and rubbing the surface of the woven fabric by a stone wash method, and the conditions of rubbing and rubbing may be appropriately adjusted in consideration of the fibrillation and the formation of island-shaped protrusions.

A swelling agent for regenerated cellulose fibers is preferably subjected to a rubbing treatment in an aqueous solution of a strong alkali such as NaOH or in liquid ammonia since it is possible to suppress the strength reduction of the fibers and generate fibrillated fibers. After forming the island-shaped convex portions, a soft finishing process may be performed, for example, by paper calendering treatment or silicone softening agent treatment, if necessary.

51 Nm viscose rayon spun yarn (twisting factor 95.
A plain weave having a warp density of 100 yarns / inch and a weft density of 56 yarns / inch was woven by alternately inserting one of the yarns 9) and using an air jet loom with a free weft exchange mechanism. Then, after relaxing and scouring according to the usual method, 5 at the same time as dyeing with a jet dyeing machine.
Rubbing for time, dry, soft finish,
A plain weave having a warp density of 116 yarns / inch and a weft density of 65 yarns / inch was obtained. The surface of the obtained fabric, the island-shaped convex portion formed intertwined fibrillated fibers about which 5000 / cm ² is formed, which accounted for about 31% in area ratio.

[0016]

Comparative Example 1 A plain woven fabric was obtained in the same manner as in Example 1 except that the rubbing treatment was carried out for 1 hour. In Example 1, a soft slimy feeling was developed without impairing the texture of Fujiet, whereas in Comparative Example 1, there was no slimy feeling, and conversely, threads were locally generated by the fibrillated fiber. It was
