METHOD FOR PRODUCING COMPLEX FUNCTIONAL UNWOVEN FABRIC OF POLYPROPYLENE LONG FIBER CONTAINING ELVAN

摘要

PURPOSE: A method for producing a complex functional unwoven fabric of polypropylene long fiber is provided to give irradiation of far infrared rays, an antibiosis and a deodorant into a long fibrous unwoven fabric formed by a polypropylene at the same time. CONSTITUTION: A complex functional unwoven fabric of polypropylene long fiber containing an elvan is produced by spinning with mixing a master batch containing a 10-30wt% elvan corpuscle of a 0.5-105 micrometers average diameter, a 0.3-1.0wt% deodorant agent of silica group and a 0.5-2.0wt% organic antibiotic agent for a polymer and a common polypropylene resin. Thereby the complex functional unwoven fabric of polypropylene long fiber is obtained to be used to various kinds of living products such as a hygienic material, a wrapping material and so on.
