摘　　要：以丙酮和水为混合溶剂,三聚氯氰和3-二甲氨基丙胺为原料,合成了N,N’-2-(4,6-二氯-1,3,5-三嗪基-2-氨基)-二甲基丙胺(TAMP)。通过FTIR和1HNMR对合成产物结构进行了表征。以脱灰软化的绵羊皮为材料,通过单因素实验确定了适宜鞣制工艺条件为:TAMP鞣剂用量20%(以灰皮质量计,下同),鞣制过程采用25、35和45℃阶梯控温模式进行,各温度模式阶段鞣制时间依次为1、1.5和3h;在鞣制坯革的染整实验中,借助于染料上染率以及坯革色泽干、湿擦坚牢度评价TAMP鞣革对染料吸收结合性能的影响。结果表明,TAMP鞣革收缩温度(Ts)可达71.5℃,粒面洁白细腻,双边撕裂强度为71.33 N/mm,抗张强度为34.00 N/mm^(2),染料上染率为96.8%,色泽干、湿擦坚牢度为2~4级。N,N’-2-(4,6-dichloro-1,3,5-triazine-2-amino)-dimethylpropylamine(TAMP)was synthesized from cyanuric chloride and 3-dimethylaminopropylamine in the mixture of acetone and water,and characterized by FTIR and 1 HNMR.The suitable tanning conditions of delimed and softened sheepskin were obtained by single factor experiment as follows:TAMP dosage of 20%(based on the mass of limed skin,the same below),the tanning process by using step temperature control mode of 25,35 and 45℃,and the tanning time of each temperature stage 1,1.5 and 3 h in turn.In the dyeing experiment of tanned leather,the influence of TAMP tanned leather on the absorption and binding properties of dyes was evaluated by the aid of dye uptake and fastness to wet and dry rubbing.The results indicated that the shrinkage temperature of TAMP tanned leather could reach 71.5℃,and the grain surface was white and delicate.The tear strength and the tensile strength was 71.33 N/mm and 34.00 N/mm^(2),respectively,the uptake of dye was 96.8%,and the color fastness to dry/wet rubbing was 2~4 grade.
