Duftabgebende Faser

摘要

Described is a fragrance-containing and fragrance-emitting polymeric fiber which optionally contains (i) at least one antimicrobial agent; and (ii) at least one compatible coloring material or color-forming material which is useful in the ascertainment of the exhaustion or substantial reduction of fragrance, produced by either (i) a processing comprising the steps of:(a) co-extruding fragrance and optionally (i) antimicrobial agent and/or (ii) at least one compatible coloring material or color-forming material which is useful for ascertainment of the exhaustion or substantial reduction of fragrance with a thermoplastic polymer to form an extrudate;(b) forming fragrance and (optionally (i) antimicrobial agent and/or (ii) at least one compatible coloring material or color-forming material which is useful for ascertainment of the exhaustion or substantial reduction of fragrance agent)-emitting particles which may or may not be foamed from the extrudate; and(c) extruding a fiber of from about 3 denier up to about 60 denier from the thus-formed particles;or (ii) a process comprising the steps of:(a) forming fragrance-emitting particles, foamed or not foamed, from a mixture of fragrance and thermoplastic polymer; and then(b) extruding a fiber of from about 3 denier up to about 60 denier from the thus-formed particles.
