  • Process for preparing a polyurethane elastic fiber
    Patent number: 6100360
    Abstract: A polyurethane elastic fiber is prepared from a polyurethane prepolymer by reaction extruding the polyurethane prepolymer and a chain extender, preferably with twin-screw extruder, and melt spinning the resulting polyurethane elastomer from the extrusion. The polyurethane prepolymer is obtained by carrying out a pre-polymerization reaction of a polyester diol and a diisocyanate, wherein the polyester diol comprises two different types of polyol, the first type being poly(tetramethylene adipate) glycol or poly(.epsilon.-caprolactone) glycol and the second type being a reaction product of a diol and dicarboxylic acid having 36 carbon atoms.
