HIGHLY ELASTIC CONJUGATE MONOFILAMENT, HIGHLY ELASTIC FABRIC USING THE SAME AND PRODUCTION OF THE FABRIC

摘要

PROBLEM TO BE SOLVED: To obtain a conjugate elastic monofilament very suitable for an elastic sheet excellent in mechanical properties and elastic recovery, to provide a highly elastic fabric using the monofilament, and to provide a method for producing the fabric. ;SOLUTION: This monofilament produced from a polyester-based elastomer of ≥2 components as a main component is provided with an anisotropic conjugate cross section having a breaking elongation of ≥80%, breaking tenacity of ≥0.5 g/d and elastic recovery of ≥90% after 30% elongated at 80°C, wherein a low melting point component B accounts for ≤50% of the cross section of the monofilament in its area ratio and for ≤50% of the whole surface area of the monofilament in its exposed area ratio, and other objects are to provide a highly elastic fabric using the monofilaments and to provide its production.;COPYRIGHT: (C)2000,JPO
