Study of the effects of time on bio-polishing of cotton knit fabrics

Abstract

Bio-polishing is a common pretreatment for knitted fabric in textile wet processing industry. This study was done to evalute the study to evalute the Bio-polishing performance on knit fabric on the basis of time factor after the scouring and bleaching and bio-polishing. We done this research on 100% cotton single jersey,(1x1) rib and interlock. This project was mainly focused of the different time (10minutes,20minutes; 30minutes) on bio-polishing of cotton knit fabrics and piling rating. The aim of the work was to measure the WPI, CPI, Stitch length ,GSM, Yarn count, Weight loss, Pilling rating of the cotton knitted fabric after the scouring, bleaching and bio-polishing process. After completing the research we found that the single jersey, (1x1) rib; interlock fabric was showing the change in WPI, CPI, GSM, Stitch length, Yarn count, Weight loss and pilling rating with the different time during the bio-polishing. After scouring-bleaching WPI,CPI, GSM are increase and stitch length, yarn count are decrease in single jersey, (1x1)rib, interlock fabrics. Otherwise after bio-polishing WPI,CPI,GSM are decrease and stitch length, yarn count are increase. Removal of the surface hairiness of fabric by Bio- polishing technique results the less energy consumption, assures improved fabric handle, leads to minimal fabric pilling tendency. Removal of hairiness of textile fiber textile materials loses weight. These weights vary in fabric to fabric. Thus after scouring-bleaching and bio-polishing single jersey, (1x1) rib, interlock fabrics loses weight. And after bio-polishing pilling rating are good.
