The present invention is directed to multicomponent fibers having a non-luminescent first polymeric component and a second polymeric component comprising a luminescent colorant. The second component comprises less than about 50 percent of the total cross-section of the fiber. The fibers of the present invention may be incorporated into fabrics useful in the manufacture of safety apparel and equipment.

Multicomponent fiber including a luminescent colorant

This invention relates to a process for preparing copolyester fibers having reduced spinning defects. More particularly, the invention relates to fibers having improved quality prepared from blends of certain poly(ethylene terephthalate) compositions modified with 1,4-cyclohexanedimethanol by melt spinning to produce filaments with decreased spinning defects while maintaining the chemical resistance, abrasion resistance, electrical and mechanical properties normally associated with copolyesters. These polymer blends when heated provide a fiber-forming polymer melt/dope which has excellent flowability and produces high quality fiber when subjected to conventional melt spinning, drawing, texturing, etc. Staple fibers prepared from the polymer blends of the invention when made into high loft battings have excellent fiberfill performance properties, particularly resilience and compression recovery.
