摘　　要：研究了带不同取代的乙烯砜基的Ｍ型活性染料在染色后，其对染色织物皂煮前后Ｋ／Ｓ值的影响，发现乙烯砜基型活性基的活泼性减小，则皂煮前后Ｋ／Ｓ值变化也减小，表明染料的皂洗牢度有所提高。Abstract The textile was dyed by M type reactive dyes containing different substituted vinyl sulfonyl type reactive groups,and the K/S values of dyeing textile before and after washing were measured.When the reactivity of vinyl sulfonyl group is deereased,the chang of K/S values was also decreased,that is to say the washing fastness of dye is improved.
