Bicomponent fiber : types, processing and applications

Abstract

Bicomponent fiber is a specific type of synthetic fibers with two different properties of polymers joined together in the same filament during spinning process. Bicomponent fibers have distinctive properties from monocomponent fibers. The properties of fibers are outcomes of type of cross section, properties of composed polymers, fiber spinning process condition, and after-treatment process. The primary applications of bicomponent fibers are self-crimping (or self-bulkiness) fibers, thermal binder fibers, microfibers and special property fibers, which can be added into the shealth of fiber. The fiber processing, types and applications of bicomponent fibers are summerised and stated in this paper.
