摘　　要：棉锦类织物通常采用二浴二步套染法染色(先以酸性染料染锦纶,再以活性染料套染棉)。然而,染艳绿色时,由于酸性染料的耐碱洗牢度较差,在碱性套染棉时,锦纶的色泽难以掌控,而且染色牢度(尤其是日晒牢度)欠佳,难以达到质量要求。实践证明:以中温型活性染料先酸性浴染锦纶,再碱性浴套染棉的一浴二段染色法,可以获得相对较好的染色效果。Cotton-nylon fabrics are usually dyed by two-bath two-step over dyeing process （Nylon is firstly dyed with acid dyes, and then cotton is dyed with reactive dyes）. However, since acid dyes present poor alkali washing fastness, the color of nylon is difficult to be controlled and color fastness （especially light fastness） is poor when the cotton is dyed in basic condition to obtain emerald green fabrics, which are not able to meet the quality requirements. It has been found that relatively good dyeing effects can be achieved via one-bath two-step dyeing process in which nylon is firstly dyed with the M-style of reactive dyes in acid bath and then cotton is dyed in alkali bath.
