摘要

Silk fibre is one type protein fibre and its coloration is also an art. Every types of natural dyestuff can be used for silk dyeing. Acid dyestuff used for silk dyeing and required more than boiling temperature, resulting fibre damage and more energy. In this research, coloured silk fabric with natural onion dye for textiles by using a method of dyeing that relies on natural ingredients extracted from onion's outer shell colorant (Quercetin) by using water and organic solvents. And also used three types of mordants such as Alum, Copper Sulphate, and Potassium dichromate. The results of the research indicated that using onion's outer shell, deeper and more stable shades of the colours were obtained in comparison with water and organic solvent extracts dyed silk fabric. All samples were better results obtained such as light fastness, rubbing, water, acid and alkaline perspiration, changes appear in a smaller extent.
