Effect of Process Variables in Air-Jet Texturing on the Properties of Spun Yarns with Different Structures

Abstract

We have analyzed the effects of process variables (texturing overfeed, air pressure) and feed material variable (yarn twist) on the important properties of air-jet textured spun yarns of different structural configurations. For this, we adopted a factorial design approach where factors are varied simultaneously in order to find the individual as well as interactive effects. Using this experimental design, we computed general re lationships relating the properties with variables as well as the significant terms in these relationships, and we plotted the response surface graphically.
