Multilobal filament, fabrics and process for making the same

Abstract

Method for producing multilobal bicomponent fiber or filaments comprising spinning at least two polymer components by bicomponent spinning system through round capillary to obtain fibers or filaments and treating fibers or filaments with hot alkali to obtain multilobal bicomponent fibers or filaments. Alternatively fabric is produced from the bicomponent fibers or filaments and treated it with hot alkali to obtain fabric comprising multilobal bicomponent fibers or filaments uniformly distributed in the matrix. The wicking property of multilobal bicomponent fibers or filaments or fabric comprising the same improved with respect to standard polyester of equivalent denier.
