用自制阳离子化羽毛蛋白助剂WLS-20对棉织物进行浸渍改性后用硫化染料染色，对比了改性与未改性棉织物的染色性能，再用此助剂对改性与未改性染色棉织物进行固色处理。在前期研究的基础上，再用此助剂对不同硫化染料用量和不同种类硫化染料染色的改性与未改性棉织物进行固色后处理，评定了WLS-20在硫化染料染色棉织物固色中的应用效果。结果表明：与未改性棉织物相比，染品在染料用量相同时，WLS-20改性棉织物比普通棉织物得色更深，经WLS-20助剂固色处理，皂洗时白布的沾色明显减少，染色织物的耐摩擦牢度、耐洗色牢度提高0.5~1级。可见，WLS-20助剂是一种多功能助剂，既能作为纤维改性剂，又可作为染色织物的固色剂。

Cotton fabric was dyed by sulfur dyestuff after it was dip-modified with WLS-20, which is a home-made cationic feather protein auxiliary. The dyeing properties of modified and un-modified cotton fabric were compared, after which WLS-20 was used in process of fixation. Based on former researches, fixation processes of WLS-20 were carried out with different sulfur dyestuffs and different dyestuff dosage, and the effects of WLS-20 on cotton fabric in fixation process were evaluated. Compared with the un-modified cotton fabric, cotton fabric modified by WLS-20 presented deeper color under the same dyestuff dosage, and the staining during soaping process was reduced significantly with the rubbing fastness and washing fastness improved by 0.5~1 level. WLS-20 is a multi-functional auxiliary, and it can be used as fiber modifier as well as fixing agent.
