Effect of Cotton/Polyester Blend Ratio, Loom Speed, and Air Pressure on Yarn Twist Loss and Yarn Strength Loss: The Case of Air-Jet Loom

Abstract

ABSTRACT Production of high-quality woven fabric with uniform fabric properties is an essential requirement for manufacturers. But in air-jet weaving, some quality parameters of the fabric are affected by twist loss of weft yarn during weft insertion. The aim of this work is to show the effect of polyester/cotton (PC) blend ratio, loom speed, and air pressure on weft yarn twist loss and tensile properties of the fabrics produced by air-jet weaving machines. Box-Behnken design has been used to design and analyze the experiment. 27 fabric samples were on an air-jet loom with a combination of four factors each at three levels (loom speed (A) 300rpm, 425rpm, and 550rpm), left side relay nozzle pressure (LSRNP) (B) (2.5 bar,3.25 bar, and 4 bar), Right side relay nozzle pressure (RSRNP)(C) (3 bar, 4.75 bar, and 6.5 bar), cotton/polyester blend (D) 100%/0%, 75%/25%, and 50%/50%,). The results of the experiment revealed that PC blend ratio, loom speed, and air pressure affect the twist level and the strength of the yarn significantly. It is found that relay nozzle air pressure is directly proportional to the twist losses and weft yarn strength loss. But the PC blend ratio has a more significant impact on weft yarn twist loss and mechanical properties of the yarn.
