PRINTING OF SILK FABRIC USING ECO-FRIENDLY TEXTILE AUXILIARIESSunita Kale, Sangita Naik and Manisha Karhale
In recent years, a lot of awareness and concern have been developed over the environmental issues particularly regarding disposal of effluents after wet processing of textiles. The use of non-allergic, nontoxic and eco-friendly textile auxiliaries has become a matter of significant importance due to the increased environmental awareness in order to avoid the use of hazardous chemicals and synthetic dyes. The natural dyes and natural thickening agents have better biodegradability and higher compatibility with environment. Thus reducing the problem of water pollution caused due to effluents of textile processing. In the present study the dried, mature Peepal bark was used as source of natural dye and white, free flowing starch extracted from waste mango kernels which had viscosity at par with that of tapioca starch was used as natural thickening agent for developing eco-friendly process of printing silk fabric. The silk fabric was screen printed using optimized concentration of natural dye-10% Peepal bark dye, natural thickening agent â 10% mango kernel starch, natural mordant- 20% myrobalan solution, 2% Ferrous Sulphate and after treated with 5% vinegar. The screen prints obtained on silk fabric were clear, sharp, of deep brown in colour and exhibited very good colour fastness to light, washing, rubbing and perspiration.
