The self-made cationic protein additives DL was used in soaping of cotton fabrics dyed with different kinds of direct dyes, and its anti-staining effects in cotton fabrics dyed with direct dyes were investigated. The results indicated that after treated by DL in soaping process, the color staining on adjacent white cloth was decreased and friction fastness, soaping fastness and wettability of the dyed fabric were improved. Lightness, saturation, hue, air permeability and wrinkle resistance almost remained unchanged.%在不同种类直接染料染色棉织物皂洗时加入自制的阳离子蛋白类助剂DL，探讨了该助剂在直接染料染色棉织物防沾中的应用效果。结果表明，经DL助剂防沾处理，皂洗时白布的沾色明显减少，染色织物的耐摩擦色牢度、耐皂洗色牢度和润湿性均有所提高。明度、饱和度、色调、透气性、抗皱性均无明显变化。
