Definitions

  • the present invention relates to a composite yarn, a knitted fabric containing the composite yarn, and a method for producing the composite yarn.
  • clothing made of hydrophobic synthetic fiber (hereinafter, also referred to as synthetic fiber) multifilament has excellent dimensional stability and wet strength, but lacks water absorption and hygroscopicity, and sweat treatment / It was inferior to humidity treatment.
  • Patent Document 1 proposes a fabric using a composite crimped yarn in which a cellulose fiber multifilament and a synthetic fiber multifilament are mixed and at least one of them is falsely twisted. It is said that the proposed fabric has less skin irritation, suppresses stuffiness, and has an excellent sweat treatment function in spite of its high cellulose fiber content.
  • cellulose is arranged in the center, and considering the sweat treatment function, cellulose which has water retention and is hard to dry is in the center. It is considered that the contact area between cellulose and the outside air is reduced, making it difficult to evaporate. Therefore, it is considered that the composite yarn structure described in Patent Document 1 is not the optimum structure for sweat treatment function, particularly for quick-drying.
  • Patent Document 2 has a structure of a composite yarn in which a hemp / rayon blended yarn is arranged in a sheath portion and a polyester filament having a modified cross section is arranged in a core portion, thereby providing both water absorption, moisture absorption and desorption, and quick drying.
  • a composite yarn that has excellent texture and is suitable for knitting underwear and sportswear has been proposed.
  • Cellulose fibers are arranged in the sheath portion, but since the cellulose fibers are blended yarns using short fibers, the porosity is large as compared with the case where cellulose filaments are used. Since water tends to stay in the voids, it is considered that the quick-drying property with respect to the filament deteriorates.
  • Patent Document 3 describes a covering technique in which cellulose filaments are arranged on the sheath side and polyester-based filaments are arranged on the core side, but the fiber bundle is wound like the covering.
  • evaporation of the outermost cellulose single yarn is promoted, but since it is bundled, water tends to stay between the cellulose single yarn and the water retention becomes high. Further, since the inside of the bundle does not come into contact with the outside air, it is difficult to evaporate, and it is expected that the quick-drying property will deteriorate. That is, as in the invention described in Patent Document 3, a method such as covering in which unopened cellulose is placed in a sheath cannot be in a form in which quick-drying is the best under any conditions.

  • Example 1 (Registered Trademark)) was single-covered on the sheath side to obtain an SCY (single-covered yarn) 110dtex78f having a sheath-core structure, and a knitted fabric having a bare heavenly structure was obtained in the same manner as in Example 1.
  • Example 1 (Registered Trademark)) was double-covered on the sheath side to obtain a DCY (double-covered yarn) 119dtex114f having a sheath-core structure, and a knitted fabric having a bare heavenly structure was obtained in the same manner as in Example 1.
  • DCY double-covered yarn
  • the knitted fabric using the composite yarn according to the present invention has good quick-drying property despite the use of highly water-retaining hydrophilic fibers, so that the fabric feels sticky after sweating and the fabric becomes sticky. There is no discomfort that sticks to the skin.
  • the hydrophilic fibers are in the outermost layer, the contact with the skin is smooth and the touch is excellent, the skin irritation is low, and the cool contact feeling is high.
  • the insensitive evaporation generated from the body can be appropriately treated by the hygroscopicity and desorption of hydrophilic fibers, so that the fabric is less stuffy and has a high overall refreshing property.
  • the knitted fabric according to the present invention has excellent elasticity and slipperiness, so that it is comfortable to wear without a feeling of restraint when worn, and clothing such as innerwear, socks, pajamas, and sports underwear that comes into direct contact with the skin. It can be suitably used as a material suitable for applications such as bedding.

Abstract

La présente invention concerne : un fil composite approprié pour un tissu tricoté qui contient des fibres hydrophiles, a une bonne texture et présente une excellente performance d'absorption d'eau/séchage rapide ; et un tissu tricoté utilisant le fil composite. La présente invention concerne un fil composite qui comprend un multifilament de fibres hydrophiles et un multifilament de fibres hydrophobes, un procédé de fabrication du fil composite, et un tissu tricoté l'utilisant, le fil composite étant caractérisé en ce qu'un degré d'ouverture de fibre représenté par la formule (1): degré d'ouverture de fibre = L/{R×√(F)) {dans la formule, R représente le diamètre équivalent en cercle d'un fil simple du multifilament de fibres hydrophiles, F représente le nombre de fils simples du multifilament de fibres hydrophiles, et L représente une distance maximale, dans une section transversale du fil composite, entre la couche la plus externe d'une zone de dispersion (SC) de fils simples du multifilament de fibres hydrophiles et la couche la plus externe d'une zone de dispersion (SG) de fils simples du multifilament de fibres hydrophobes} est inférieur à 1,0, le rapport fibres hydrophiles/SG n'est pas supérieur à 20 %, et le rapport, par rapport à la SG, d'une zone (S) où la SG et la SC se chevauchent n'est pas inférieur à 80 %.
