One Step Printing and Functionalization of Microwave Pretreated PET Fabric Using New Azo Amino Thiazole Disperse Dye

Abstract

This study represents a successful and simple method for printing and finishing polyester fabrics by adapting a new aminothiazole disperse dye and microwave technique. Microwave pretreatment of polyester fabrics was carried out under a variety of conditions in terms of the microwave power and time. Afterwards, the printed samples were fixed using both conventional techniques and microwave energy. The color strength expressed as K/S of the printed samples was evaluated in addition to CIELAB coordinates (L*, a*, and b*), which were also measured. Washing, rubbing, and light fastness properties were evaluated for samples prepared by both conventional and microwave fixation techniques. Scanning electron microscopy (SEM) was used to investigate the morphological characteristics of the treated printed samples. The biological activity of the synthesized dye against gram-positive bacteria and gram-negative bacteria was also evaluated. The obtained results clarified that the prints obtained using microwave treatment and new dyes have better color strength, stable brilliant color, good fastness properties, and highly durable antibacterial activity when compared to those of conventional techniques using thermofixation and steaming.
