  • the present invention relates to a fabric that is lightweight and thin and has high strength, low air permeability, and excellent glossiness. More particularly, the present invention relates to a fabric that is lightweight and thin and has high strength, low air permeability, and excellent glossiness, comprising a polyamide fiber with a fine size and a flat multifoliar cross section.
  • a fabric used for sportswear requires high strength, in particular, improved tear strength and improved wear resistance.
  • the fabric particularly when subjected to a coating process such as laminating, is less likely to cause yarn slippage and thus tends to have reduced tear strength, and accordingly, improvement in tear strength of a base fabric has been increasingly desired.
  • fabrics made of a polyester multifilament, nylon multifilament, or conjugate fiber thereof have often been used for down wear, material for sports, and the like due to their excellent mechanical properties.
  • Such fabrics are soft, lightweight, and excellent in properties such as windbreak, water-repellency, and fastness, and thus have often been used for, for example, coats, blousons, golf wear, and outdoor wear for sports.
  • Patent Document 1 discloses, as a means for solving the problem of high strength and reduction in weight and thickness, a fabric comprising a synthetic multifilament, wherein by subjecting the fabric to calender processing on at least one surface, monofilaments are pressed overlapped each other in at least a part of the synthetic multifilament, the synthetic multifilament having a fineness of 7 dtex to 44 dtex, wherein the monofilaments have a Y-shaped or cruciform cross section, the fabric having a cover factor of 1300 to 2200.
  • Patent Document 1 JP 2010-196213 A
  • the fabric obtained by the method disclosed in Patent Document 1 has a gloss with glitter and streaks because of uniformly reflected light, and is unsatisfactory in appearance, such as glossiness of products, as well as functionality.
  • there are fabrics satisfying the required properties such as high strength, reduced weight, and reduced thickness in the prior art but glossiness has not been considered sufficiently, and there has been no fabric having a delicate and elegant gloss.

  • nylon 6 and nylon 66 are preferred, and nylon 6 is more preferred.
  • the degree of polymerization of the above polyamide is preferably 2 or more in terms of relative viscosity in 98% sulfuric acid, more preferably 3 or more.
