摘　　要：为得到一种适用性强、地色均匀丰满、染色牢度高的羊绒制品拔染印花加工方法,分析了拔染印花染料与助剂的选择及拔染剂的用量对织物拔白程度、K/S值的影响,探讨了温度对染料提升力和可拔性的影响。结果表明:偶氮多丽兰染料适合用作羊绒织物拔染印花的地色染料,拔染剂朗茄烈C、BR-1(复配)是适合于羊绒制品拔染印花的拔染剂,用量应控制在11%～13%;随朗茄烈C、BR-1用量的增加,兰纳芯染料在地色织物上的K/S值呈上升趋势;在85～95℃下,酸性多丽兰染料染色提升力良好,温度的提高对织物拔白程度有一定的影响。According to the characteristics of cashmere fabric,a discharge printing process is suggested which has good applicability,even and full ground color,and high color fastness.Selection of dyestuffs and auxiliaries for discharge printing of cashmere fabrics was discussed,and the influence of discharging agent amount on the discharged whiteness and the K/S value of the fabric as well as the influence of temperature on the build-up of dyes and dischargeability were studied.The results demonstrated that acidic dye Duolilan and discharging agent Langqielie C and BR-1（compound） were suitable for the ground shade in discharge printing,and the dosages of both dyes and discharge agent were in the range of 11%-13%.The K/S value of Lanasyn S dyed ground shade increased with the increase of dosage of Langqielie C and BR-1.Acidic dye Duolilan exhibited good build-up property when dyeing was carried at 85-95 ℃ and the discharged whiteness of fabrics was affected by temperature.
