POLYLACTIC ACID CRIMPED YARN AND TWISTED CRIMPED YARN

摘要

PROBLEM TO BE SOLVED: To obtain a polylactic acid crimped yarn for making process passage in the production of the crimped yarn and a carpet product using the crimped yarn consistent with physical properties required in use as the carpet product.;SOLUTION: The polylactic acid crimped yarn is constituted of a polylactic acid polymer having 13-22 relative viscosity and has 60-2,000 dtex total fineness, 1.9-3.2 cN/dtex tensile strength and 3-12% crimp elongation percentage after boiling water treatment.;COPYRIGHT: (C)2004,JPO
