Abstract

The melanin of yak hair is a biomaterial with unique features and functions. We investigated the properties of woolen woven when coated with yak hair melanin. Natural melanin was extracted from yak hair by the method of acid hydrolysis. The woolen woven was coated with 5%-10% owt melanin, 0.8 g/l sodium hydroxide (NaOH), and acetic acid (CH3COOH), at a liquor ratio of 1:40 at 96°C for 30 min. Melanin, extracted from yak hair, has the potential to become a natural dye. But converting it into leuco form with the help of a reducing agent makes it dyeing ability. From the UV/Vis spectrophotometer, SEM, and EDS analysis results, it can be seen that the melanin is completely absorbed into the wool fibers. Also, woolen woven is coated with melanin, the good 3/5-4/5 color fastness, the tensile strength of the fabric has improved by warp 53.53%, weft 45.87% but the elongation has reduced by warp 10.79%, weft 18.3%, and the thermal properties of woolen textiles are improved by 23%. It is a step towards developing future clothing materials that reduce environmental stress.
