With the characteristics of controllable charge and environmental friendliness, amphoteric polymers can be used in post-tanning process to solve the problems that arise during leather making and are caused by the low absorption rate of single-charge chemicals, incompatibility with new tanning methods, and complex operation process. In this review, the structure, performance, and preparation of amphoteric polymers are reported. Then, the charge change of collagen during different tanning and pH treatments is introduced. Finally, the application and development of amphoteric polymers during the post-tanning process of leather making are discussed. This review has certain guiding significance to the preparation and application of amphoteric polymers for tanning system.

两性聚合物在皮革后鞣过程中的应用

具有可控电荷和环保的特性,两性聚合物可用于鞣制后的过程中,以解决制革过程中出现的问题,这些问题是由单电荷化学物质的吸收率低,与新的鞣制方法不兼容以及操作过程复杂。在这篇综述中,报道了两性聚合物的结构,性能和制备。然后,介绍了在不同的鞣制和pH处理过程中胶原蛋白的电荷变化。最后,讨论了两性聚合物在制革后鞣制过程中的应用和发展。该综述对鞣革体系两性聚合物的制备和应用具有一定的指导意义。
