Investigation of the Dyeability of Cotton Fabrics with a Halochromic Dye According to Exhaust and Padding Methods

ABSTRACT

Smart textiles are an important field in textile since these products are high-added value. One of the applications of smart textiles is chromic textiles, which can be used as a sensor. As is known, exhaust and padding dyeing are the basic methods and for this reason in this study process optimization for application of a halochromic dye (bromcresol purple) to cotton by these methods was carried out. According to experimental results, it can be said that dyeings according to exhaust method using wool dyeing process was successful for cationized cotton. On the other hand, pigment dyeing process used by garment dyers did not give satisfactory results in terms of fastness. In addition, the optimum conditions for padding method were determined as 5 g/L dye and 20 g/L binder. Fabrics showed very good color changing ability with regard to pH both with acid-base solutions and acid-base vapors. Accordingly, it can be said that both exhaust and padding methods can be used for dyeing with halochromic dyes, if optimum conditions are determined.

摘要

智能纺织品是纺织品的一个重要领域, 因为这些产品具有高附加值. 智能纺织品的应用之一是可以用作传感器的铬纺织品. 众所周知, 排气染色和轧染是基本方法, 因此, 在本研究中, 通过这些方法对棉花上使用的卤代染料 (溴甲酚紫) 进行了工艺优化. 根据实验结果, 可以说采用羊毛染色工艺的排气法对阳离子棉进行染色是成功的. 另一方面, 服装染色厂使用的颜料染色工艺在牢度方面并没有给出令人满意的结果. 此外, 确定了填料法的最佳工艺条件为5g/L染料和20g/L粘合剂. 织物在酸碱溶液和酸碱蒸汽中都表现出很好的pH变色能力. 因此, 可以说, 如果确定了最佳条件, 排气法和轧染法均可用于卤代铬染料的染色.
