Various types of chain extenders were used as hard-segment of the polyurethane yarn made of poly ε-caprolactone diol (PCL) as a soft-segment, and their physical and elastic properties were compared. It was found that ethylene diamine as the chain extender is siutable, because of it′s good balanced physical and elastic properties. And the introduction of urethane bond made of glycol and aromatic group into hard-segment is recommended to improve tensile elongation and wet heat set of the polyurethane yarn.
