AN ELASTIC INTERLACED TEXTURED YARN

摘要

Air textured yarn is provided to reduce the lengthening by having excellent elastic recovery property which is similar to elastic recovery property of fabric manufactured out of covering yarn of spandex yarn. Air textured yarn having elasticity comprises: polyester latent crimp filament yarn(2) having 1-6 denier of mono-fineness and total 30-150 denier of fineness; and polyester filament yarn(1) having 0.3-4 denier of mono-fineness and total 70-300 denier of fineness. The air textured yarn has 30-50% of the coefficient of expansion and over 90% of elastic recovery rate.
