ABSTRACT

The need for an environmentally friendly tool in textile production is the major concern of consumers and traders. The current study is aimed to use supercritical CO2 technology to improve dyeing of minor elastin containing cotton using CI. Reactive Blue 222 and CI. Direct Black 112 dyes. For this purpose, several minor elastin containing cotton were pretreated with both conventional water and supercritical CO2 methods. Physical properties such as mass per unit area, tensile strength, tear strength, and elasticity of these fabrics are studied. Obtained results show that the supercritical CO2 pre-treatment affects some of the physical parameters.

Furthermore, the obtained results are very promising as they prove that it is possible to dye various base-cotton fabrics in supercritical CO2 medium with a very satisfying quality in terms of uniformity and conformity.

摘要

纺织品生产中对环保工具的需求是消费者和贸易商最关心的问题. 本研究旨在利用超临界CO2技术,对含少量弹性蛋白棉的CI染色进行改进。活性蓝222和CI. 直接黑112染料. 为此,采用常规水和超临界CO2方法对几种含少量弹性蛋白的棉进行预处理. 研究了织物的单位面积质量、拉伸强度、撕裂强度和弹性等物理性能. 结果表明,超临界CO2预处理对某些物理参数有影响. 实验结果表明,在超临界CO2介质中对各种基棉织物进行染色,在均匀性和一致性方面都有很好的应用前景.
