عنوان انگلیسی Environmentally Dyeing of Wool Yarns Using of Combination of Myrobalan and Walnut Husk as Bio-mordants
چکیده انگلیسی مقاله Today, it is important to pay attention to the reduction of toxic effluents and pollution caused by industrial effluents. The textile industry and dyeing procedure is one of the most important industries in the world, and its effluent causes environmental pollution. Reducing the use of chemical compounds in the dyeing process can reduce these adverse effects. In this article, the aim is to investigate the use of the natural colorant of Madder in the presence of a mixture of two natural tannins-rich mordant (Myrobalan and Walnut husk). For the application of mordant, the pre-mordanting method is used and their performance is compared with Alum. A mixture of two natural mordant with different percentages, the total of which will be 10 %, was used. The changes in the application of the mordant and the natural dye of the yarns are evaluated using the FTIR test. The removal of the peak related to C-N bonding indicates the proper interaction between the mordant, the dye and the yarns. The results illustrated that the use of mordant and increasing the dye concentration increases the color strength. The results showed that the best percentage of mordant mixing is WH:YM=7.5 %:2.5 %. ISO standards were used to check the fastness properties of dyed yarns and moderate to good results were obtained.
