DEODORIZING NONWOVEN FABRIC AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a nonwoven fabric excellent in durability and comprising acrylic synthetic fiber having high deodorizing performance against various offensive odors emitted in daily life, and to provide a method for producing the nonwoven fabric. SOLUTION: This nonwoven fabric comprises acrylic synthetic fiber composed of a copolymer A with acrylonitrile as the main constituent unit and 1-40wt.% of a polymer B miscible with the copolymer A but incompatible therewith. In this case, the polymer B is in a phase-separated state, containing 0.5-20wt.% fine powder with a metal silicate or metal aluminosilicate 0.5-10μm in average particle size as active ingredient and also bearing 0.1-20wt.% of an amino compound.
