                 Abstract:  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  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.
                                                                                2
                 The tear strength and the tensile strength was 71.33 N/mm and 34.00 N/mm , respectively, the uptake of
                 dye was 96.8%, and the color fastness to dry/wet rubbing was 2~4 grade.
