Effect of Dye Dispersion Preparation on Disperse Dyeing Performance on Polyester Fabric

Abstract

The effect of dye dispersion preparation prior to dyeing on the dyeing ability of the disperse dye on polyester fabric was studied. The influence of sodium laurylsulphate (SLS) concentrations and the homogenization process was determined. The optimum SLS concentration for dyeing observed in this study was 0.01 M. The color yield of the dye passing through the homogenization process on polyester fabric was higher than that from the conventional dye preparation. Homogenization was also found to enhance disperse dyeability at a lower dyeing temperature. It infers that the dyeing process could be done at a lower temperature. The dyeing temperature could be as low as 110oC in the presence of homogenization. The effect of homogenization on the dyeability at different dyeing times was also examined.

Study of Energy-Saving Dyeing Process for Poly(lactic acid) Fabric

“…Disperse Red 167.1 was applied on 2g PLA fabric at 0.5, 1, 2 and 4 %owf in the presence of different dispersing agents at a liquor ratio of 10:1. SLS was used at 0.01M [3] whereas Sera sperse was employed at 1 g/l. The pH of dyebath was adjusted to 5 using acetic acid and sodium acetate.…”

Preparation of Aqueous Nanodispersions of Disperse Dye by High‐Gravity Technology and Spray Drying

“…A wide range of approaches have been developed for the synthesis of disperse dye nanoparticles, including media milling [8], high-pressure homogenization [9], emulsion polymerization [10,11], supercritical fluid technology [12,13], and antisolvent precipitation [14,15]. Among these methods, it is an effective procedure to prepare disperse dye nanoparticles by antisolvent precipitation, which has the advantages of low cost, simple process, time-saving, and easy industrial scale-up [16,17].…”
