PRODUCTION OF ANTIMICROBIAL NONWOVEN FABRIC COMPRISING POLYURETHANE ELASTIC FILAMENT

摘要

PURPOSE:To obtain antimicrobial nonwoven fabric comprising polyurethane elastic filaments having excellent thermal performance and to provide a method for producing the nonwoven fabric industrially and advantageously. CONSTITUTION:A molten thermoplastic polyurethane elastic material is mixed with a polyisocyanate compound and an antimicrobial agent and spun from fine holes to give filaments, which are sent by a high-speed air flow, sprayed, piled in a sheetlike state and collected to give a method for producing antimicrobial nonwoven fabric comprising polyurethane elastic filaments.
