抄録

The relationships between soft-segments and the elastic properties of polyurethane yarns were studied. Poly ε-caprolactone diol(PCL), ε-caprolactone(CL)-ethyleneoxide(EO) copolymer diol, PCL-polypropylene glycol (PPG) block copolymer diol, PCL/PPG blend and polytetramethylene glycol (PTG) were used as soft-segments. The effects of molecular weight and molecular weight distribution of diols, and also the effects of chain length of soft-segments on the elastic properties of polyurethane yarns were examined. It was found that the permanent set of polyurethane yarn was related to the chain length of soft-segment and the melting point of diol.
