The Argazol TW reactive dyestuffs were involved in the dyeing process. The parameters under different conditions such as exhaustion, fixation,compatibility as well as soaping fastness were investigated in detail. It is shown that the Argazol TW reactive dyestuffs are suitable for dyeing of blends of Tencel and shrink-proofing wool and good dyeing behavior can be expected.展开更多
