BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spun and twisted yarn used for knitted fabrics, handicraft yarns, braids and the like.

[0002]

2. Description of the Related Art As a material for clothing for spring and summer or a material for non-clothing, a yarn made by mixing hemp with a sharp taste is popular, but as a drawback of using hemp, there is no luster, and the texture that is sharp and opposite is hard. It has been pointed out. On the other hand, as a method of bringing the yarn close to the hemp texture without using hemp, a method of fusing the constituent fibers by heat or a solvent is known.
Although it has a crisp taste, it has the drawbacks that the texture is hard, the gloss is insufficient, and the texture of the spun yarn is difficult to obtain. Conventionally, it is known that, for example, spun yarn of acrylic fiber spun yarn and viscose rayon multifilament yarn is twisted, but it has a hard texture, and the surface of the eye, that is, the size and arrangement of the stitches constituting the stitch, and the dirty state Met.

SUMMARY OF THE INVENTION The present invention provides a spinning-twisted yarn that solves the above-mentioned drawbacks of the prior art.

[0004]

Means and Actions for Solving the Problems The present invention resides in a finely spun and twisted yarn, wherein the multifilament yarn to be twisted is a regenerated cellulose multifilament yarn. The regenerated cellulose multifilament yarns used in the present invention include cupra and viscose rayon, and those obtained by the net process method and the continuous spinning method are particularly excellent in gloss as compared with the cake method and the hank method. Therefore, it is preferable to use a boiling water shrinkage ratio of 5 to 8% obtained by the continuous spinning method because the softness and the sharpness are further excellent.

The regenerated cellulose multifilament yarn of the present invention is a composite yarn in which 50% or more, preferably 80% or more of the fibers constituting the yarn surface are occupied by the regenerated cellulose multifilament yarn, for example, a twisted yarn, It also includes mixed yarn. As the regenerated cellulose multifilament yarn of the present invention, wool is used as the fiber yarn to be mixed with the yarn,
There are cotton, linen, acetate, polyester, polyamide, etc., and synthetic fiber typified by polyester, twisted yarn, design yarn, different shrinkage mixed yarn, spontaneously stretched mixed yarn, carded yarn such as polyester. A high elongation yarn such as a highly oriented undrawn yarn (POY) and a low elongation yarn such as a polyester regular yarn, a cationic dyeable yarn or a spin take-up yarn spun at a winding speed of 6000 m / min or more. It may be used in combination with a draw-aligned entangled false-twisted yarn or a spun yarn, and may be appropriately selected as desired.

As the regenerated cellulose multifilament yarn of the present invention, in particular, two or more kinds of regenerated cellulose multifilaments having a boiling water shrinkage ratio of 1.5% or more, preferably 2% to 12% (regeneration having different boiling water shrinkage ratios). Cellulose multifilament can be obtained by changing the spinning method of regenerated cellulose multifilament, for example, the boiling water shrinkage is Hank method, Cake method <Net process method <
The continuous spinning method is large in order, and these may be appropriately combined as desired. ) Mixed twisted yarns, mixed yarns, and regenerated cellulose multifilaments having a boiling water shrinkage greater than that of regenerated cellulose multifilaments, for example, high shrinkage polyester fibers and polyester different shrinkage mixed yarns, and regenerated cellulose multifilament feed rates To increase false twisting or entanglement,
It is preferable to use a mixed yarn or a composite yarn that has been subjected to fluid injection processing, since a swelling feeling is added.

The sliver or roving yarn, which is finely spun and twisted with the regenerated cellulose multifilament yarn, includes natural fibers such as cotton and wool, cellulose fibers such as cupra and rayon,
One or more of synthetic fibers such as acrylic, modified fibers having modified pill resistance, etc. may be appropriately used according to the purpose, and the fiber length may be short cotton, 2 inches, 3 inches, or worsted hair, Non-shrinkable cotton or shrinkable cotton may be used. The single yarn denier is 0.1 to 3.0 denier, preferably 0.4 to 1.
0 denier is good because it gives a soft texture. The count and twist coefficient of the spun-twisted yarn are not particularly limited, and may be appropriately selected within the range of 1/30 to 1/200 for the count and 40 to 100 for the twist coefficient, for example.

If necessary, the fine spinning intertwisted yarn may be used by twisting at 100 T / m or more, preferably 500 to 2000 T / m. After being temporarily twisted, it is knitted and woven, and then textured in a dyeing step. To be done. Examples of the textured knitted fabric include crepe (palace, flat, décin, Yangyanagi, Oriental, Georgette), voile, chilimen and the like. or,
Other fiber yarns that are interwoven and knitted may also be used as twisted yarns, and as the twisting direction, S twist and Z twist may be alternately used for the warp and / or the weft. In addition, when weaving or weaving such a spun mixed twisted yarn, it may be mixed with other fiber yarns depending on the desired texture of the knitted fabric, and the mixed fiber yarns disclosed in the above-mentioned composite yarn of regenerated cellulose multifilament are Available.

A knitted or woven fabric using the spun and twisted yarn of the present invention can be prepared, for example, by a normal pressure washer, a continuous relaxing machine, a jet dyeing machine,
Regenerated cellulose multifilament yarn by a kneading process in a wet state (if necessary, in a swelling agent, for example, an alkaline aqueous solution such as NaOH) in a flow dyeing machine or a Wins dyeing machine, or by rubbing the surface of a knitted fabric by a stone wash method. When made into fibrils, the texture becomes even softer, and an appropriate slimy feel is also obtained. Further, in order to obtain a softer texture, the amount may be reduced by a cellulase enzyme, or further reduced and then fibrillated.
