Abstract

The present invention has a difference in elongation of at least 50 The present invention relates to a method of manufacturing a composite twisted yarn having a texture such as wool having a dry refreshing feeling composed of two or more polyester filaments, and the filaments constituting the small-scale screening are hexamite, oval, S-Z alternating yarns having single yarn fineness of 0.8 ~ 2 denier in the periphery of single yarn fineness having 3 ~ 6 denier Since the polymorphic cross-section of the core is partially expressed by the enclosed shape, the contact area of the skin is relatively smaller than that of the composite twisted yarn using the circular cross-section yarn, so that the composite twisted yarn of the consumption tank expressing a dry refreshing feeling can be obtained.

The present invention has at least 50 new cars It relates to a method for producing a polyester composite twisted yarn having the same texture as wool composed of two kinds of filament groups described above.

As one of the means for the natural fiber of the polyester fiber, it may be combustible processing. However, the biggest drawback of flammable processing is that the touch is monotonous and the yarn has a rich, natural appearance and dry refreshing feeling.

Therefore, as a result of earnest research to improve the flawability of the flammable processing, while utilizing the bulkiness and productivity of the flammable processing, the present invention is to manufacture the composite flammable fabrication.

Multi-processing expresses the frayed fiber structure, twisted structure, and wool structure, which are the structural characteristics of wool yarn, and gives rich bulkiness and soft feel, natural and spun sense appearance, static repulsion and drape. By combining the easy-care properties of the ester to provide a polyester composite combustible having a wool-like texture.

Conventionally, Japanese Unexamined Patent Publication Nos. 7-126944, 7-11529, and Patent Publication Nos. 94-11311 and 88-474 disclose the use of a circular cross-section yarn as a material yarn for composite twisted yarn. Satisfactory effects can be achieved in terms of height, repulsion, and soft touch, but more differentiated yarns have been required to cope with consumer's preference for comfort.

Therefore, the present invention is characterized by using the following polymorphic cross-section yarn as a screening of composite twisted yarn in order to obtain a comparatively easy and simple and maximum differentiation effect. The polymorphic cross section yarn referred to herein refers to yarns that are spun by using single or mixed four types of spinnerets in FIG. In other words, in order to realize the more differentiated touch while maintaining the advantages of the existing composite twisted yarns, we have manufactured the eccho composite fabrication with the Taesumido filament group with small elongation of polymorphic cross-sectional view and the superfine circular finesse filament group.

Shinto Difference is 50 In case of composite processing using less than two kinds of yarn as material yarn, it is not possible to form the poncho structure, and it is possible to obtain yarn close to general combustion processing, so the difference in elongation is at least 50 It should be ideal.

The present invention is a consumable-tank composite twisted yarn which simultaneously gives a dry refreshing feeling, moderate repulsion feeling and soft touch by a differentiated material yarn called polymorphic cross section, and the dry refreshing feeling is around the filament group around the core filament group in which the filament group at the beginning is polymorphic cross section yarn. It is wound in the shape of alternating Z, and the filament is mixed with each other at the boundary of screening and superficial yarn. When the polymorphic cross section of the core is partially expressed, the skin contact surface is circular circular yarn. It is expressed because it is relatively smaller than the composite twisted yarn fabric using.

Such a sheath structure can provide a fabric having a good spanlike appearance and feel, and at the same time prevent the separation of the core portion and the sheath, and obtain good passability and longitudinal form stability of the yarn structure in the processing and weaving process. In addition, it has softness due to superfine yarn of fine fineness of 0.8 ~ 2 denier with single yarn fineness, and at the same time, it has proper resilience by screening of single fineness of 3 ~ 6 denier.

3 ~ 6 denier is suitable for single yarn road of filament group of Taeseomdo 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 give moderate resilience, 3-6 denier is best.

Single fineness of fine fine filament group is 0.8 ~ 2 denier. In order to give soft touch, it is preferable to use 2 denier or less. However, if it is too denier, it is too soft touch, resulting in a heterogeneous touch with the texture such as consumable fabrics, and apparent dyeing is difficult, making it difficult to concentrate. The best.

The present invention will be described in more detail with reference to directors and comparative examples.
