Abstract

Innovation concerned with hybridization of nanosiezed chitosan with nanoparticles of a disperse dye under the onset of sonication was studied. Three techniques were outlined describing the nanoparticles preparations of chitosan, disperse dye and chitosan /disperse dye nanoparticles. Thus obtained hybrid nano colorant auxiliary was found to possess different hydrophobic/hydrophilic characteristics as well as variable color intensity depending upon the ratio of the disperse dye in the chitosan/dye mix. When applied to textile fabrics (flax, polyester, and polyester/flax blend) as per the pigment printing technique, the nano colorant hybrid display multifunction antibacterial activity and coloration ability. The prepared nanoparticles of chitosan/ disperse dye were characterized using TEM and XRD. The coloured hybrid was applied in textile printing using silk screen technique. The printed samples were evaluated by measuring colour strength, fastness properties, means of print fixation and antibacterial activity.

壳聚糖/分散染料纳米粒子，用于同时印刷和抗菌整理

摘要

研究了超声作用下纳米级壳聚糖与分散染料纳米粒子杂交的创新。概述了三种技术，描述了壳聚糖，分散染料和壳聚糖/分散染料纳米粒子的纳米粒子制备。根据壳聚糖/染料混合物中分散染料的比例，发现由此获得的杂化纳米着色助剂具有不同的疏水/亲水特性以及可变的颜色强度。当按照颜料印花技术应用于纺织品（亚麻，聚酯和聚酯/亚麻共混物）时，纳米着色剂杂化物显示出多功能的抗菌活性和着色能力。使用TEM和XRD对制备的壳聚糖/分散染料纳米颗粒进行表征。使用丝网印刷技术将有色杂种应用于纺织品印花。通过测量色强度，色牢度特性，印刷固定方式和抗菌活性来评估印刷样品。
