Abstract
Multicomponent fibers having an outer exposed surafec include a polyarylene sulfide polymer component and at least one additional component formed of a different polymer. The polyarylene sulfide polymer component forms the entire exposed surface of the fiber and imparts good thermal and chemical resistance to the fiber.
Claims25
A multicomponent fiber having an exposed outer surface, comprising:
- at least a first component comprising a polyarylene sulfide polymer, wherein said polyarylene sulfide polymer forms the entire exposed surface of the multicomponent fiber;
- and
- at least a second component free of polyarylene sulfide polymer and free of liquid crystalline polymer and contacting at least a portion of said first component, said second component comprising a substantially insoluble polymer selected from the group consisting of isotropic semi-crystalline polyesters and polyolefins.
