Post-tannageIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : 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.

SurfactantsIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : A fatliquor is an indispensable agent for leather, giving softness, fullness and elasticity. A quaternary ammonium salt cationic surfactant (cetyl-dimethyl-(3-methacrylamide) propyl bromide (DMPC16)) was synthesised from N-(3-dimethylaminopropyl) methacrylamide (DMAPMA) and hexadecane bromide by nucleophilic substitution reaction. The structure and properties of quaternary ammonium cationic surfactant were characterised by FTIR, 1H-NMR, elemental analyser, TGA and surface tension analyser. Further, it was applied in the fatliquoring process of wet-white (Clariant EasyWhiteTan F-90 tanning system to test the physical and mechanical properties, softness, air permeability and absorptivity of the fatliquoring leather. The results showed that quaternary ammonium salt cationic surfactant was successfully prepared, and its surface tension was 31.87mN/m. The application tests showed that the absorption rate of fatliquor reached 97.8%. At the same time, the softness and physical and mechanical properties of the treated leather were improved, including softness increased by 109%, tensile strength increased by 17.2%, tear strength increased by 50.1%, and air permeability increased by 891.21L/(cm2.h). The results showed that quaternary ammonium cationic surfactant had good fatliquoring properties in F-90 tanning system, which can improve the softness, tensile strength and tear strength of leather.
