Abstract

A novel approach in the field, a range of new azothiazole dyes substituted with different hydrophobic groups, was utilized as colorants for dyeing polyester fabrics in a supercritical carbon dioxide environment. The innovative dyes were analyzed using standard spectroscopy techniques and elemental analysis. The dyeing process was assessed for its dyeing ability, color strength, and color fastness for twelve different dyes. The polyester fabrics dyed with these dyes appeared in various shades, between red and magenta. Using the AATCC method, the antibacterial assessment revealed that some dyes exhibited significant antibacterial properties against both positive and negative bacteria. All 12 dyes showed outstanding resistance to washing, rubbing, and light, with staining and color change ratings of 4–5. The results indicate that the synthesized dyes could be employed for large-scale, energy-efficient, and environmentally friendly polyester fabric dyeing utilizing supercritical carbon dioxide.

新型噻唑偶氮染料在超临界二氧化碳中的一步染色及抗菌处理

在超临界二氧化碳环境下，利用不同疏水性基团取代的新型偶氮噻唑染料作为着色剂对涤纶织物进行染色是该领域的一种新方法。采用标准光谱技术和元素分析对新染料进行了分析。对该染色工艺对12种不同染料的染色能力、色强和色牢度进行了评价。用这些染料染色的涤纶织物呈现出不同的色调，介于红色和品红之间。采用AATCC法对染料进行抑菌性评价，发现部分染料对阳性菌和阴性菌均表现出明显的抑菌性能。所有12种染料都表现出优异的耐洗涤、耐摩擦和耐光性，染色和颜色变化等级为4-5。结果表明，合成的染料可用于大规模、节能、环保的超临界二氧化碳涤纶织物染色。图形抽象
