The Effect of Bio-polishing on Knit Fabric Properties

Abstract

The term Bio-polishing is a process which normally formed before or after dyeing and which can improve the fabric handling and superiority. Mainly it reduces the hairiness of fabric. This project was done to check the physical property of fabric before and after bio-polishing. So in this case we took 100% cotton s/j, 1x1 rib and interlock fabric to evaluate the change of physical property by using different types of chemical and by maintaining proper time and temperature. After the experiment we realized that after bio-polishing the CPI, WPI, GSM decreased and yarn count and SL increased before than scouring and bleaching. It also increase handle properties and decrease hairiness of the surface of the fabric before than the scouring and bleaching process. It removes pills and also improves the luster that is very important for a proper fabric surface to make standard garments.
