Abstract: The hard elasticity of polypropylene hollow fiber can be obtained on crystallization under high stress after heat treatment. The factors affecting the hard elasticity of the fiber are studied through SEM, WAXD and strain-stress tests.

Key words: polypropylene, hard elasticity, strain induced crystallization
