Abstract

PURPOSE: Woolen type polyester different shrinkage mixed yarn is characterized by using polyester drawn yarn, core yarn containing titanium oxide type particles and silicone oxide type particles and using half-drawn yarn, sheath yarn having spontaneous extensibility. Textile manufactured out of the yarns has excellent bulkiness and repulsive property. CONSTITUTION: Polyester different shrinkage mixed yarn is obtained by the steps of: preparing polyester drawn yarn containing 1-3pts.wt. of titanium oxide type particles having 80-400nm of average diameter and 1-3pts.wt. of silicone oxide type particles having 20-200nm of average diameter; spinning half-drawn yarn at 2000-4000mpm of spinning velocity; using the polyester drawn yarn, core yarn having high hollow ratio; using the half-drawn yarn, sheath yarn having spontaneous extensibility; and then air-confounding the polyester drawn yarn and the half-drawn yarn to be mixed in a raito of 1:0.7-1:1.3. The hollow ratio of the polyester drawn yarn is 15-40%.

Description

Wool imitation polyester biaxial blend fiber superior in dry feeling

The present invention relates to a polyester bi-shrink blend yarn having excellent dryness giving a feeling of hairiness while being rough in the fabric, but having excellent volume and repulsion. It relates to a method for producing a polyester biaxially blended yarn blended by an air entanglement treatment with a screening and spontaneous stretchable polyester semi-stretched yarn as a superfine yarn.

In the invention related to the conventional bi-shrink blended yarn, a method of manufacturing polyester bi-shrink blended yarn having a silky texture by blending high-stretched yarn of general polyester or non-stretched yarn with polyester is disclosed in Korean Patent Publication Nos. 97-810 and 97-. 811, which is known from patent publications No. 97-812 and Patent Publication Nos. 95-18766, which have a soft pitch. It did not escape the category of perception.

In the present invention, a special material not previously used, that is, using a high-strength drawn yarn containing a large amount of particles as a screening to develop a wool imitation material excellent in dry feeling. Of course, low shrinkage hollow yarns are used for blending, as in Korean Patent Publication No. 95-18766, but in this case, the hollow yarns are used as superfiber yarns, so the repulsive properties of the fabric are lower than those used for screening. do.

The present invention incorporates 1 to 3 parts by weight of titanium oxide particles having an average particle diameter of 80 to 400 nm, and 1 to 3 parts by weight of silicon oxide particles having an average particle diameter of 20 to 200 nm. By using polyester stretched yarn as a screening, these particles express fine uneven surface on the surface of yarn after dyeing, and give dry and rough texture without the greasy taste peculiar to synthetic fiber. Titanium oxide and silicon oxide have a specific gravity of 3.9 and 2.3, respectively, so that the specific gravity is higher than that of polyester having a specific gravity of about 1.38, thereby maintaining drape.

The high hollow fiber of the present invention has a high hollow ratio of 15 to 40%, and is excellent in volume and resilience, and is mixed with spontaneous elongated semi-stretched yarn spun at a spinning speed of 2000 to 4000mpm, so that it is combined with a loop formed after salt processing. Woolen fabric with bulky volume of fabric

It plays a major role in making you feel. At this time, if the hollow ratio of the hollow yarn is 15% or less, it is insufficient to express the unique characteristics of the hollow yarn.

A load phenomenon occurs, which makes machining difficult and reduces drape.

Titanium oxide-based particles that are incorporated into the particles are also used as matting agents.

It is about 2.55, so the color of the yarn is higher than 1.62 of polyester

When dyed and whiter than semi-polyester, it expresses pastel colors. So

In the case of heavy hollow fiber containing a large amount of titanium oxide-based particles, the color difference occurs with the semi-drawn yarn having a high dyeing yield. If this color difference occurs unevenly locally, it looks messy and deteriorates the quality of the product. However, in the present invention, the composition of high-strength drawn yarn and undrawn yarn containing particles in a ratio of 1: 0.7 to 1.3 results in uniform color difference. Mel

Designed to look like a Ranji effect.

As described above, the polyester bishrink horn of excellent wool imitation is mixed with the rough dryness due to the particle content and the melange effect due to bulkyness, volume, repulsion and uniform color difference due to high hollow and spontaneous elongation. The thread can be produced.

Hereinafter, the present invention will be described in detail with reference to Examples and Comparative Examples.

Example 1

Hollow detained polyester containing 1.5 parts by weight of titanium oxide and 2.0 parts by weight of silicon oxide

Through 75denier / 36filament hollow drawn yarn of 20% hollow rate at a spinning speed of 5000mpm

Joe. And 85denier / 36filament spontaneous extension semi-extension

Two yarns at a mixing speed of 400mpm, air pressure 3.0㎏ / ㎠, nozzle 1.4ψ

Entangle At this time, the number of entanglements is 60 to 100. The manufactured blended yarn was opened with 1200 TM

It is used for both light and weft yarns after dead end, and weaved into plain weave

All. At this time, the weight loss should be around 10%.

Comparative Example 1

Weaving and processing were carried out under the same conditions as in Example 1 except that 3 parts by weight of silicon oxide was mixed without using titanium oxide in the stretched yarn.

Comparative Example 2

General semi-circle circle containing 0.4 parts by weight of titanium oxide without using silicon oxide in the stretched yarn

Weaving and processing were carried out under the same conditions as in Example 1 except for signing.

Comparative Example 3

Weaving and processing are carried out under the same conditions as in Example 1 except that the stretched yarn is a general circular cross section yarn, not a hollow yarn.

Comparative Example 4

Weaving and processing were carried out under the same conditions as in Example 1 except that the undrawn yarn was 123 denier / 36 filament.

Results according to the Examples and Comparative Examples are shown in Table 1 below. The evaluation was a sensory evaluation of 10 people. When eight or more people agreed, excellent (◎), five or more people were normal (○), and less than (△).

Table 1

As can be seen from the above results, in the case of hollow fiber and not in the sense of remarkable feeling and repulsion much fall, when the particles are not used, the overall effect is inadequate and the tone effect does not appear if titanium oxide does not enter among the particles. . In addition, when the ratio of the yarn to yarn is higher than that of the yarn, the yarn is almost on the surface of the fabric, so the tone effect is insufficient and the dryness of the yarn is not expressed.
