WETNESS-RESPONSIVE FIBER, PROCESS FOR PRODUCING THE SAME, NONWOVEN FABRIC, AND USE OF THESE

摘要

A wetness-responsive fiber which is characterized by comprising a monofilament formed from a resin composition comprising a base resin as an optional ingredient, a resin having anionic groups, and a resin having cationic groups. It can be produced by melt-kneading a resin composition comprising a base resin as an optional ingredient, a resin having anionic groups, and a resin having cationic groups and then spinning the melt. The nonwoven fabric comprises fibers formed from a resin composition comprising a cationic resin and an anionic resin and optionally containing a regenerated cellulose. This fabric is usable as a body fluid absorbent and wet tissue. It can be subjected to beating in water.
