Natural dyeing on wool with indigo, and yellow dyes kamala, berberine, onion peel, amla, anar and palas in combination with indigo

摘要

Studies were conducted to extract natural dye from biomass products namely indigo, kamala, berberine, onion peel, amla, anar and palas. Extracted natural dye was used for dyeing on mordanted wool with alum and copper. In all 16 different variety of blue and greens shades were developed, which are rare. L~*la~*b~* values and fastness properties (light, wash & crocking) were also studied on these samples. This area offers a need to carry out further research in this field and explore the possible way for other fibrous products viz. Tute, cotton etc.
