Abstract (en)
[origin: EP3643817A1] The purpose of the present invention is to provide a polyurethane-nylon 6 eccentric sheath-core conjugate fiber which can obtain an excellent soft stretchable woven/knitted fabric and ensure the appearance quality of stockings. The present invention relates to an eccentric sheath-core conjugate fiber being characterized by having: (1) a core component of a thermoplastic polyurethane; and (2) a sheath component of nylon 6, wherein the curvature of a cross section is 15% or less and the CV value of the curvature of a cross section is 0.40 or less.
