Abstract

PURPOSE:To obtain the title yarn having soft handle by blending specific man- made fiber staple with wool yarn. CONSTITUTION:(A) Man-made fiber staple such as polyester having <=80g/d apparent Young's modulus is blended with (B) wool yarn, average fineness x average fiber length of the component A is made >= four times as much as the value of the component B and further the ratio of the component A is made <=50wt.% based on the whole yarn to give the objective yarn for clothes.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a fabric yarn containing soft-textured wool fibers.

(Prior Art) Conventionally, when artificial fiber staples such as polyester staples are used in a blend with wool fibers, they have been manufactured and used by matching the fiber shapes of the two fibers as much as possible. Therefore, polyester staples of 3dX70 to 100II11 have been used for blending with wool fibers. Of course, the reality is that for large-count wool fibers, polyester staples with a large fineness of 5d class are used.

(Problem to be solved by the invention) However, these blended yarns are used for spring/summer products that take advantage of the firm touch of polyester, and at present, loose blended yarns are the mainstream for spring/summer suits. It becomes.

Incidentally, in recent years, there has been a demand for softer textures, and there has been a demand for softer yarns that contain wool fibers.

(Means for Solving the Problems) The object of the present invention is to provide a yarn for fabrics that contains wool fibers and has a soft texture, and takes the following means to solve the problem of darning. . That is, in the present invention, an artificial fiber staple whose apparent Young's modulus is 80 g/d or less and a wool fiber are combined, and the product of the average fineness (d) and the average fiber length (INll) of the wool fiber is the artificial fiber. For fabrics, characterized in that the product of the average fineness (d) of the staples and the average fiber length (north) is more than 4 times greater, and the amount of the artificial fiber stable is 50% by weight or less based on the entire yarn. It's a thread.

The present invention will be explained in detail below. In the present invention, in the case of a blended yarn consisting of wool fibers and stable artificial fibers, it is effective to make the fiber diameter of the artificial fibers extremely thin, and at the same time, to meet the requirement for a soft texture. By increasing the number of fiber tips, the eyebrows are made softer. However, if the diameter and fiber length of the artificial fibers are incorrectly selected for wool fibers, it will not be possible to obtain the desired soft texture.

Therefore, in the present invention, the product of the average fineness (d) and the average fiber length (mm) of the wool fiber is 4.
The aim is to achieve a soft texture by increasing the size by more than double the size. In addition, the average fineness of the artificial fiber stable is preferably 0.8 to 1.3 d. The fineness of standard wool fiber is 21.5 microns (=4.3 d), and empirically, if you want to obtain a soft texture, it is at least 1/1
This is because a fineness of 3 is required. Further, the average fiber length is preferably 50 to t35+nm. This is also because wool fibers have a length of 75 to 85II11, whereas a shorter length is effective in obtaining a soft feel. Further, the apparent Young's modulus of the artificial fiber is 80 g/d or less, preferably 70 g/d or less. In terms of appearance, if the Young's modulus exceeds 80 g/d, the soft texture characteristics will be suppressed, which is not preferable.

Furthermore, the artificial fiber stable has a
It is 0% by weight or less, preferably 25 to 40% by weight. In addition, the average fineness (d) of the wool fiber is 4.0 to 5. Od is preferable, and the average fiber length (north) is also preferably 75 to 85 m.

The blending of the wool fiber and the artificial fiber stable is preferably carried out in a pre-spinning process close to the spinning process. Examples of man-made fibers include polyester fibers, polyamide fibers, polyacrylic fibers, Promix fibers, benzoate fibers, and the like.

In addition, the twist coefficient (metric) applied to the yarn is 85 to 1
00 is preferred.

(Example) Example 1 Wool fiber (average fineness 5.Od (=23.2 microns)
, an average fiber length of 85 mm) (8 g/m );
Sliver (4 g/m ) of polyester staple (average fineness 0.8 d, average fiber length 51 + 1.) at 2:1
Blended in the ratio of I/48 (metric) (32
It was spun with a twist number of 0 T/m (m coefficient 89.4).

The blending rate of wool was 67% by weight. The fabric woven from this yarn by double-thread processing did not have the texture of conventional polyester fibers, but had a moderate stiffness and a soft surface to the touch, just like wool fibers.

(Effects of the Invention) Although the fabric yarn of the present invention is a blended yarn, it does not lose the texture of wool fibers, and has a soft texture, and retains this characteristic even when the wool fibers are thickened. Met.
