Abstract
Multicomponent fiber and a method of producing the same whereby the inter-domain boundary layer between the distinct domains is surface roughened and/or mechanically modified so as to increase the surface area contact (and thereby the adhesion) therebetween. As such, delamination of the domains at their interfacial boundary layer is minimized (if not eliminated entirely). Preferably, the fibers are concentric core-sheath bicomponent fibers whereby the core is surface roughened and/or mechanically modified so that of the inter-domain boundary layer between the core and the sheath appears in cross-section to be serrated, undulated and/or ribbed so as to provide a core domain with a shape factor of between about 25 to about 55.
