  • the course direction was adopted, and in the case of woven fabric, the elongation rate and the recovery rate in the direction in which the elastic yarn used was stretched (the average value for both warp and weft) were adopted.
  • Example 2 ⁇ [0090] 44 decitex cross-linked polyolefin elastic yarn (Toyobo Co., Ltd .; DOWXLA), 56 6 decitex 68 filament polyester and 100's cotton fiber composite spun yarn equivalent to No. 60
  • Example 21 The same operation as in Example 2-1 was performed, except that 44 dtex 12 filament vinylon fiber was used as the constituent fiber of the composite spun yarn instead of the polyester fiber. As in Example 21, it was possible to obtain a bare tentacle knitted fabric having a beautiful flower-pattern watermark pattern from which cotton fibers were dissolved and removed. The stretch rate of this knitted fabric was 62%, and the stretch recovery rate was 81%. Ratio 2— ⁇
  • Example 2-1 The same operation as in Example 2-1, except that 44 dtex polyurethane elastic yarn (Espa 465 manufactured by Toyobo Co., Ltd.) was used instead of 44 dtex cross-linked polyolefin fiber-based elastic yarn. It was. The polyurethane elastic yarn was dissolved by the acid, and only the polyester fibers remained in the fabric. Holes were pierced in some places, and no floral watermark was formed. The stretch rate of this fabric was 53%, but the stretch recovery rate was 42%, which was poorly recoverable.
  • 44 dtex polyurethane elastic yarn Espa 465 manufactured by Toyobo Co., Ltd.
  • the composite elastic yarn of the present invention is excellent in chemical resistance and weather resistance, it is a swimsuit, inner wear, outer wear, diaper cover, sanitary goods, outdoor registrars such as tent sheets, and industrial materials. It can use suitably as materials, such as.
  • the stretchable fabric of the present invention has a beautiful appearance with a watermark pattern in addition to excellent stretchability, and therefore can be suitably used as a material for inner wear, sportswear and the like.

Abstract

Fil extensible conjugué comprenant une fibre polyoléfinique extensible et une fibre polyoléfinique non extensible. La fibre polyoléfinique extensible est une fibre polyoléfinique extensible réticulée ou une fibre similaire, tandis que la fibre polyoléfinique non extensible est une fibre de polyéthylène à masse moléculaire élevée ayant une masse moléculaire moyenne en poids de 10 x 105 ou plus, ou une fibre similaire. Ce fil extensible conjugué est satisfaisant comme matériau pour gants. En outre, l'invention propose un tissu extensible à motif ajouré qui comprend une fibre polyoléfinique extensible réticulée et une fibre non extensible, et qui est ajouré en retirant totalement ou partiellement la fibre non extensible par attaque chimique partielle.
