【摘要】 以特定醛基含量的氧化淀粉为预鞣剂,FeSO4和荆树皮栲胶为基本鞣剂,研究了预处理剂及第一组分对有机-无机结合鞣中第二组分鞣剂渗透速度的影响,通过测定各阶段鞣液中鞣剂的浓度间接探讨了植物单宁-金属鞣剂结合鞣中第一组分对第二组分的阻尼作用,同时也确定了鞣制时间对革坯耐热稳定性的贡献,结果显示:结合鞣第一组分的加入对后续鞣剂的渗透有一定的阻尼性,但是渗透到胶原内部的各鞣剂总量几乎不受影响;氧化淀粉预处理后,该阻尼性更明显,后续加入的组分渗透更缓慢;经由氧化淀粉预处理后革坯的耐热性更好,最高的Ts可达90.5℃。更多还原

【Abstract】 Tanking oxidized starch with particular aldehyde content,FeSO4 and mimosa as pre-tanning agent and basic tanning agents,the influence of pre-tanning process on the penetrating rate of the second tanning agent was researched.And by testing the concentration of agent at different stage,the damping effect of the first constituents to the second tanning agent has been discussed,and the contribution of time to hydrothermal stability also has been studied.The results show that the first component has impact to the permeation of second agent,and the total mass was specific.The penetration of following agent become more slowly after pretreated by oxidized starch.And the shrinkage temperature of leather tanned with oxidized starch,mimosa and FeSO4 can reach to 90.5 ℃.更多还原
