HYDROPHILIC POLYOLEFIN NONWOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To obtain a hydrophilic polyolefin nonwoven fabric having excellent water absorption properties and durable hydrophilicity. SOLUTION: The hydrophilic polyolefin nonwoven fabric in which a hydrophilizing agent is substantially fixed to polyolefin fibers is obtained by modifying the surface of a nonwoven fabric by corona discharge or normal-pressure plasma discharge and treating the surface with the hydrophilizing agent. The hydrophilic polyolefin nonwoven fabric has≥60mN/m wet tension,≤0.25 second initial spot absorption rate and≥80% third durable water permeability index. COPYRIGHT: (C)2004,JPO
