The present invention relates to a method for producing a waste tank composite twisted yarn having a dry refreshing feeling composed of two kinds of filament groups having a difference in elongation of at least 50% or more.

Polyester fibers have originally been aimed at developing natural fibers, and one of the means is combustible processing. However, the biggest drawback of bitumen processing is that the touch is monotonous and the complex, rich and natural luxury and appearance of the yarn are far below. Therefore, the production technology researched to improve the bulkiness and productivity of the flammable processing, but to improve the flaws of the flammable processing, is the complex flammable processing.

Multi-processing provides polyester with abundant bulkiness, soft texture, natural and spontaneous appearance, and moderate repulsion and drape. It appeared to combine with care.

Conventionally, in Japanese Patent Laid-Open Nos. 7-126944, 7-11529, and Korean Patent Publication No. 94-11311, and Patent Publication No. 88-474, the material yarns of composite twisted yarns are circular in cross-section with aquatic yarns. In addition, it was satisfactory in terms of soft touch, but more differentiated yarns were needed to cope with consumer's preference for comfort.

Therefore, in the present invention, the polymorphic cross section yarn is used as the screening method of the composite twisted yarn as the easiest and simplest method to obtain the maximum differentiation effect. The polymorphic cross section yarn referred to herein refers to yarns that have been spun by using four or four spinnerets in FIG. 1 alone or in combination. In other words, in order to realize more differentiated touch while maintaining the advantages of the existing composite twisted yarns, we have manufactured the ultra-concrete composite construction with the Taesumido filament group with small elongation of the polymorphic cross section and the superfine yarn with the finer finer filament group.

In the case of composite processing using two kinds of yarns with less than 50% of the difference in elongation, the difference in elongation should be at least 50%, since the planting structure cannot be obtained.

The present invention is a combustible composite twisted yarn which simultaneously gives a dry refreshing feeling, moderate repulsion feeling and soft touch by the differentiated material yarn called polymorphic cross section, and the dry refreshing feeling is around the filament group of the core part where the filament group at the beginning is polymorphic cross section yarn It is wound in the shape of S, Z alternating edges, and it is a structure in which each filament is mixed with each other at the boundary between screening and superficial yarn. It is expressed because it is relatively smaller than the composite twisted yarn fabric using the single-sided yarn.

Due to such a sheath structure, it is possible to provide a fabric having a good spanlike appearance and feel, and at the same time to prevent separation of the core portion and the sheath, and to obtain good passability and longitudinal shape stability of the yarn structure in the processing and weaving process. Moreover, it has the softness by the superfine sand of fine fineness of 0.8-2 denier of single yarn fineness, and has moderate resilience by the screening of 3-6 denier of single yarn fineness.

3-6 denia is suitable for Dansa Island road in the filament group of Taeseom Island. If it is less than 3 denier, the repellency comparable to wool-consumed fabric cannot be obtained in the case of the woven fabric. If the denier is larger than 6 denier, the repellency is excessive, the rough and hard feel is obtained, and the sewing property is also worsened. In order to provide moderate resilience, 3-6 denier is the best.

The fine yarn fineness of the fine fine filament group is 0.8 to 2 denier. In order to impart soft touch, it is necessary to use 2 denier or less, but if it is too denier, the soft touch will be excessive, resulting in a heterogeneous touch with the texture of the consumed tissue, and apparent dyeability will also be reduced, making it difficult to thicken salts. The best.

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

Example 1

Multi-processed stretch yarn 75/24 of polymorphic cross section consisting of low elongation and 1: 1 ratio of leaf and elliptical cross section (filament number and fineness) and 80/72 high-strength, circularly aligned cross-section yarn under the following conditions Was carried out.

Fire speed: 400

Elongation Ratio: 1.040

Belt speed ratio: 1.700

Θ angle: 107.5

1st heater temperature: 185 ℃

Pre-interlaced overfeed and air pressure: 1.5%, 4㎏ / ㎠

Second overfeed: 3.50%

3rd overfeed: 2.60%

After weaving the yarn thus manufactured with 1280T / M of soft water, weaving it into 7200 sheets of warp yarns, 110 yarns / inch of warp density, and 62 yarns / inch of greeting density. It was.

The results of the sensory evaluation of the fabrics are as shown in Table 1, and a fabric having dry coolness and having a moderate repulsive feeling, bulkiness, and softness was obtained.

Example 2

Polymorphic cross-section yarn 150/48 and partial orientation yarn 122/72 in which the yarn of low elongation of the yarn was spun together were subjected to composite processing under the following conditions.

Fire speed: 400

Elongation Ratio: 1.035

Belt Speed Ratio: 1.701

Θ angle: 112.5

1st heater temperature: 185 ℃

Pre-interlaced overfeed and air pressure: 2.5%, 4㎏ / ㎠

Second overfeed: 2.45%

Third overfeed: 2.77%

After the yarn was twisted with 1200T / M of soft water, the fabric was manufactured under the processing conditions of general polyester long fiber fabrics. The result of sensory evaluation as in Example 1 obtained the results as shown in Table 1. The fabric which had bulkyness and a soft feeling was obtained.

Example 3

150/48 stretched yarn manufactured using spinnerets having a cross-section cross section of FIG. 1 was used as the screening, and fabrics were made in the same manner as in Example 2 for the superfine yarn, microfiber processing, and dyeing processing.

As a result, a result as shown in Table 1 was obtained, and a fabric having a dry refreshing feeling and a moderate repulsion feeling, bulkiness, and soft feeling was obtained.

Comparative Example 1

Composite processing was performed under the same conditions as those of Example 1 of the stretched yarn 75/24 of the circular cross section and the partially aligned yarn 80/72 of the circular cross section.

The fabric was prepared under the same conditions as in Example 1 to obtain a good resilience, bulkiness, and soft feel, but no dry refreshing feeling (see table).

Comparative Example 2

Polymorphic cross-section yarn 85/12 and partial alignment yarn 80/72 having the same cross section as Example 1 having a single yarn fineness of 7 denier were subjected to composite twist processing under the same conditions as in Example 1.

When the woven fabric was fabricated in the same manner as in Example 1 with this yarn, the resilience was so great that a rough, hard touch was obtained. (See table)
