One-Bath Dyeing and Finishing Process of Polyester Fabrics

Abstract

Simultaneous dyeing and finishing processes of 100% polyester fabrics with disperse dyestuff were carried out using exhaust dyeing method (high temperature method). A finishing chemical was added with different concentrations into dyeing bath. Fabrics were evaluated with respect to hydrophility, volumetric resistivity, colour measurement, soil-releasing test and fabric performance tests like bending strength, crease recovery, air permeability, thickness. It is concluded that samples dyed with 4% chemical is statistically different than reference sample in terms of hydophility and volumetric resistivity and samples dyed with 6% chemical is different than reference sample in terms of bending strength, crease recovery and air permeability. Samples dyed with 4% chemical have miminum colour difference according to reference sample and also have miminum colour difference after soil release test for soil 1 and soil 2. However samples dyed with 6% chemical have minimum colour difference for soil 3.
