MULTIPLE DOMAIN FIBERS AND METHODS OF MAKING THE SAME.

摘要

Multicomponent fibers have a primary core, and multiple secondary cores equidistantly radially spaced from one another and from the primary core. The primary and secondary cores are entirely embedded within (and thus completely encased by) a primary sheath. Optionally, the primary sheath may be entirely or partly surrounded by a secondary sheath. The primary and secondary cores may be spun from polymers having distinctly different or complementary properties which are surrounded by a sheath or sheaths formed of another polymer(s) which protects the cores.
