The Environmentally Benign Extraction of Peanut Red Skin for Textile Coloration and its UV Protection Properties

摘要

Customer requirement for environmentally dyes leads to the resuscitation of natural colorants for textiles, using newer energy adequacy dyeing processes and reproducible shade developing processes. This article reports a study for extraction of dyes from peanut red skin by using microwave heating and its application for textile print via flat screen method. Dyestuff concentration and pH factors were studded. Effect of print paste conditions namely; pH, dyestuff concentration, kind of thickener and mordant type were studied. Color strength, color data and fastness properties of the printed textiles were also investigated. UPF protection factor was determined for the mordanted and unmordanted fabrics. The results showed that the printing paste that contains 30% of extracted dye, thickened with seed My pro gum at pH 9 and fixed by hot steam at 100°C for 30 min. gives the highest K/S value.
