Abstract
A blended staple fiber yarn having a high grade cotton yarn-like touch, hand and appearance and superior mechanical strength, abrasion resistance, flame resistance and scratching resistance is comprised of 30 to 80 parts by weight of extremely fine polyester staple fibers having a denier of 0.9 or less and 20 to 70 parts by weight of super high modulus staple fibers having a Young's modulus of 4000 kg/mm.sup.2 or more, and can be produced by a specific draft zone system spinning process in which individual filaments are drawn-cut and the resultant staple fibers are cohered to each other to form a spun yarn.
Claims2
A blended synthetic staple fiber yarn fabric comprising blended synthetic staple fiber yarns having a high-grade cotton yarn-like touch and comprising a blend of a first group of extremely fine polyester staple fibers having a thickness of not more than 0.9 denier and a second group of super high modulus staple fibers comprising a para-type aromatic polyamide and having a thickness of not more than 1.0 denier and a Young's modulus of not less than 4000 kg/mm.sup.2, said first fiber group and said second fiber group having an average length of at least 70 mm and being present in a blend ratio of said first fiber group to said second fiber group from 40:60 to 70:30 by weight.
