Abstract (en)

[origin: WO2014075987A1] The present invention relates to a bicomponent fiber, comprising i) a first thermoplastic polyurethane component;and ii) a second thermoplastic polyurethane component, which may be the same as or different from component i), with at least one of components i) and ii) crosslinked by a crosslinker to form at least one polymer of polymer i) and polymer ii), of which polymer i) has a melting point of at least 10˚C higher than that of polymer ii), and the fiber size being between 8 denier and 300 denier, more preferably between 10 denier and 100 denier. The bicomponent fibers of the present invention are superior in heat-bonding behavior and recovery, and may be dyeability and chemical-resistance.
