An Approach for Linen Fabrics Coloring and Antibacterial Activity by Cumin in Combination with Nano Copper and Iron

ABSTRACT

Flax fibers have always a special place among the whole consumed fibers owing to customer demands related with its characteristic features. This is why investigating alternative finishing methods to transfer different features to these fibers along with coloration is an important issue. In this study, it is aimed to color linen fabrics with cumin seeds and to diversify the obtained colors by using sodium sulfate (Na₂SO₄) in different amounts during the extraction and dyeing periods as well. Additionally, copper and iron in powder form was used during cumin-based finishing processes to achieve coloration and antibacterial features. To see the effect of using sodium sulfate and copper/iron powders in finishing, the solely cumin-based dyeings were also carried out as well. As a result of the study, it was observed that cumin seeds can be used for coloring the fabrics and the presence of sodium sulfate in extraction and so in dyeing period enhance the obtained colors darker which means lower L* values in CIE L*a*b* color space. Meanwhile the color yields (K/S) become higher too. Furthermore, it was also found that the presence of copper nano-powder during dyeing has a significant effect on color yields and provide antibacterial activity against Escherichia coli and Staphylococcus aureus.

摘要

亚麻纤维因其自身的特性，在整个消费纤维中占有特殊的地位. 这就是为什么研究替代的整理方法，以转移不同的特点，这些纤维随着着色是一个重要的问题. 本研究以孜然籽为原料对亚麻织物进行染色，并在浸提和染色过程中使用不同量的硫酸钠（Na2SO4）使亚麻织物的颜色多样化. 此外，铜和铁的粉末形式是在孜然为基础的整理过程中使用，以实现着色和抗菌功能. 为了观察硫酸钠和铜铁粉在整理中的效果，还对孜然染料进行了单独染色. 研究结果表明，孜然籽可用于织物染色，硫酸钠在萃取和染色过程中的存在使所得颜色变深，这意味着CIE L*a*b*颜色空间的L*值较低. 同时颜色产率（K/S）也变得更高. 此外，还发现纳米铜粉在染色过程中的存在对显色率有显著影响，并对大肠杆菌和金黄色葡萄球菌具有抗菌活性.
