摘要： A process for producing foamed thermoplastic polyurethane particles comprises the steps of a) melting a thermoplastic polyurethane in a first extruder (E1), b) injecting a gaseous blowing agent in a second extruder (E2), c) impregnating the gaseous blowing agent homogeneously into the thermoplastic polyurethane melt in a third extruder (E3), d) extruding the impregnated thermoplastic polyurethane melt through a die plate and granulating the melt in an underwater granulation device under temperature and pressure conditions to form foamed thermoplastic polyurethane particles.

摘要： The present invention discloses a thermoplastic polyurethane comprising substantially no plasticizers and having a Shore A hardness of 60 or less, which is prepared by a one-step polymerization of i) linear polyol, ii) organic diisocyanate and iii) glycol chain extender mainly comprising ethylene glycol and/or 1,3-propanediol; wherein the linear polyol (i) has a number average molecular weight within the range of from 1.5×103 g/mol to 5.0×103 g/mol. The thermoplastic polyurethane of the present invention can be easily produced by conventional production methods, and the thermoplastic polyurethane thus produced can be molded to articles in practicable processing cycles. Moreover, the thermoplastic polyurethane articles have low shrinkage, have good low-temperature properties and good mechanical properties, and do not harden substantially at low temperature.

摘要： 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.
