Title:
ANTIMICROBIAL FIBER AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JPH0345709
Kind Code:
A
Abstract:
PURPOSE: To obtain the title fiber exhibiting no lowering of physical performance of a fiber itself, having resistance to abrasion and stable antimicrobial physical performance free from falling off, by adding a reducing agent to a mixed aqueous solution of PVA and specific water soluble salt of a metal of tin, etc., to form a metal colloid and then spinning the mixed solution.
CONSTITUTION: A reducing agent (e.g. formaldehyde or hydrazine) is added to a mixed aqueous solution of PVA and at least one or more water soluble salts of metal selected from Sn, Pb, Cu and Ag to form a metal colloid. Then the mixed solution is spun to provide the aimed fiber. Furthermore, the content of metal colloid particles is preferably 0.0001-5.0wt.
