Reuse of Discharged Liquor for Polyester Dyeing Project

Abstract

The qualities of polyester fibre that are revealed following disperse dyeing are the main focus of this thesis. This thesis compares several kinds of attributes. I will start by dying a polyester sample cloth in a sample dyeing pot. Once the dyeing process is finished, we will take a sample from the dyeing pot. There will be some dye solution left over at this point, so I'll dye it again using a fresh sample of fabric. I will then review the CMC report. In a similar manner, I will dye a sample of polyester fabric. Following dyeing, the fabrics display a variety of tints. I can compare this shade in a different way based on visual evaluation.This thesis examines the properties of polyester fabric, includingits colourfastness to rubbing, colourfastness to washing, colourfastness to water, colourfastness to saliva, colourfastness to sweat, colourfastness to dye transfer, colourfastness to phenolic yellowing, pH value, and bursting strength. Check the CMC report as well.
