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° C. or above as measured by a differential scanning calorimeter (DSC) and containing 3.00x10⁶ 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 mum in diameter. An elastic nonwoven fabric comprises the fiber mixture.
