Study on Dyeing of Lyocell Knitted Fabric with Grape Seed Extract Dyes

Article Preview

Abstract:

The natural vegetable dye grape seed extract (GSE) was applied on the direct dyeing of lyocell knitted fabric. By changing the dyeing condition, the modified process was derived after evaluating various fastnesses of the dyed fabric. The direct dyeing method should be under the condition of GSE’s concentration 5g/L, bath preparation temperature 80°C, pH value 3, bath ratio 1:30, dyeing time 60min. The color is very sensitive to pH and GSE’s concentration. The rubbing fastness, washing fastness and light fastness is good, the acid perspiration fastness is better than the alkaline perspiration fastness.
