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的主要关注点。目前的研究旨在使用超临界 CO ₂技术改进使用 CI 对含少量弹性蛋白的棉花的染色。活性蓝 222 和 CI。直接黑 112 染料。为此，用传统的水和超临界CO ₂方法对几种含有少量弹性蛋白的棉花进行了预处理。研究了这些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。获得的结果表明，超临界CO ₂预处理会影响一些物理参数。

此外，所获得的结果非常有前景，因为它们证明了在超临界CO ₂介质中对各种基棉织物进行染色是可能的，并且在均匀性和顺应性方面具有非常令人满意的质量。
