MIXED FIBER AND, STRETCH NONWOVEN FABRIC COMPRISING SAID MIXED FIBER AND METHOD FOR MANUFACTURE THEREOF

摘要

A fiber mixture according to the invention comprises fibers A comprising a polymer A containing a thermoplastic polyurethane elastomer and fibers B comprising a thermoplastic polymer B other than the thermoplastic polyurethane elastomer, said thermoplastic polyurethane elastomer having a solidifying point of 65 DEG C or above as measured by a differential scanning calorimeter (DSC) and containing 3.00x10<6> or less polar-solvent-insoluble particles per g counted on a particle size distribution analyzer, which is based on an electrical sensing zone method, equipped with an aperture tube having an orifice of 100 mu m in diameter. An elastic nonwoven fabric comprises the fiber mixture.
