Air-jet texturing: Effect of jet type and some process parameters on properties of air-jet textured yarns

Abstract

The distinguishing features of different air texturing jets have been described and the test methods used to assess some important properties of air textured yarns have been discussed. The properties of air textured yarns produced using various currently used commercial jets have been compared. The results show that the performance of cylindrical jets and Taslan type XX jet for parallel end texturing of 76 den/36 fil polyester yarns is superior. The effects of some important process parameters such as overfeed percentage, air pressure and heater temperature on various properties of air-jet textured yarns have been reported. The relationships between air-jet textured yarn properties and processing parameters have been assessed in terms of regression equations and it has been shown that with a few exceptions, most of the properties of air-jet textured yarns are linearly related to the process parameters studied.
