MULTI-COMPONENT FIBERS, NONWOVEN WEBS, AND ARTICLES COMPRISING A POLYDIORGANOSILOXANE POLYAMIDE

摘要

Nonwoven webs are described wherein the web has an inverted MVTR of at least 10,000 g/m2/24 h and a resistance to water penetration of at least 10 min according to EN-20811. In a favored embodiment, the nonwoven web comprises a multi-component fiber. Also described are multi-component fiber comprising a core and outer layer and nonwoven webs comprising such. At least a portion of the outer layer comprises a first melt processable composition comprising a polydiorganosiloxane polyamide copolymer. The core comprises a second melt processable composition that does not comprise a polydiorganosiloxane polymer. The multi-component fiber comprises 5 to 25 wt-% of the polydiorganosiloxane polyamide copolymer
