Studies on the characteristics of Pre-heated air-jet textured yarns.

摘要

Pre- heated polyester and nylon air jet textured yarns were produced by heating them before the air nozzle of air jet texturising machine. Regular air jet textured yarns of polyester and nylon filament yarns were also produced without heating them. Regular and pre- heated textured yarns characteristics were compared. It was found that preheating of filament improves loops frequency, loops stability, bulk, tenacity and breaking elongation. The polyesterylon blended air textured yarn showed more loop frequency than polyester and nylon air textured yarns.
