Abstract

PURPOSE: To obtain a durable water absorbing web excellent in chlorine resistance by melt blow spinning a polybutylene terephthalate having a specific value or above of intrinsic viscosity(IV) into fibers having a specific average fineness or below and forming oxygen-containing functional groups bound to the polybutylene terephthalate molecular chain on the surface of the resultant formed nonwoven fabric. CONSTITUTION: This durable water absorbing web excellent in chlorine resistance is obtained by melt blow spinning a polybutylene terephthalate having >=0.4 value of IV into fibers having <=0.8 denier average fineness, forming a nonwoven fabric, further carrying out a plasma treatment of the surface of the nonwoven fabric and forming oxygen-containing functional groups bound to the polybutylene terephthalate molecular chain.
