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.

新型偶氮氨基噻唑分散染料对微波预处理的PET织物的一步印花和功能化

这项研究代表了一种通过采用新型氨基噻唑分散染料和微波技术对聚酯织物进行印染和整理的成功而简单的方法。就微波功率和时间而言,在多种条件下对聚酯织物进行微波预处理。然后,使用常规技术和微波能量将印刷的样品固定。表示为颜色强度K / S的印刷的样品的除了CIELAB坐标(评价大号*一个*,和b *),也进行了测量。对通过常规和微波固定技术制备的样品的洗涤,摩擦和耐光性进行了评估。扫描电子显微镜(SEM)用于研究处理过的印刷样品的形态特征。还评估了合成染料对革兰氏阳性细菌和革兰氏阴性细菌的生物活性。所获得的结果表明,与使用热固和蒸煮的常规技术相比,使用微波处理和新型染料获得的印刷品具有更好的色强度,稳定的鲜艳颜色,良好的坚牢度特性和高度耐用的抗菌活性。
