The Influence of Structure Parameters of Weft Knitted Fabrics on Propensity to Pilling

Abstract

Pilling of knitted fabrics persist a serious problem for apparel industry. Pilling means generation of pills over the surface of the fabric. The main cause of pilling of knitted fabrics there is mechanical action, first of all abrasion during wear. The main goal of this work was to investigate the influence of main structure parameters of weft knitted fabrics on propensity to pilling. The samples were knitted on a circular single face, rib, and interlock knitting machines from PES yarns, cotton yarns, and cotton yarns combination with PU yarns. The samples were grouped according to knitting structure, raw material, yarn linear density, and fabric density. The test was carried out according to EN ISO 12945-1:2000 Pilling Box method. There were estimated the influence of knitting structure, raw material, yarn linear density, and fabric density on propensity to pilling of weft knitted fabrics. The results of experiments can be used for engineering design of weft knitted fabrics.
