HIGH ELONGATION SUPERFINE FILAMENT NONWOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To stably provide a high elongation superfine filament nonwoven fabric by melt-spinning polymers into conjugated filaments and then treating a nonwoven fabric composed of the conjugated filaments with water without using a chemical agent or the like. SOLUTION: This method for producing the high elongation superfine filament nonwoven fabric is characterized by water-dissolving (A) a water-soluble thermoplastic polyvinyl alcohol having a saponification degree of 90 to 99.9 mol.% from a filament nonwoven fabric composed of superfine filament-formable conjugated filaments comprising (A) the polymer and (B) a polypropylene having a MFR of≤30 or a polyethylene terephthalate-based polyester copolymerized with≥8 mol.% of isophthalic acid.
