This invention relates to a multicomponent fiber having an exposed outer surface, comprising at least a first component of polyarylene sulfide polymer, and at least a second component of a thermoplastic polymer free of polyarylene sulfide polymer, wherein said thermoplastic polymer forms the entire exposed surface of the multicomponent fiber.

Multicomponent fiber with polyarylene sulfide component

The present invention is directed to a spunbond fiber comprising polyphenylene sulfide polymer having a zero shear viscosity at 300&#xb0; C. of about 21,500 to about 28,000 Pa&#xb7;s.

Polyphenylene sulfide spunbond fiber

A process is disclosed for flash spinning a nonwoven fibrous sheet from a polymeric solution containing about 12% to 33% by weight of filler particles. The filler is preferably insoluble in the polymer. The resulting plexifilamentary film-fibril sheet material has increased breathability with no decrease in liquid barrier.
