猪皮防水革的工艺影响因素及性能的研究

Processing Influence Factors and Properties of Waterproofing Pigskin Leather

猪皮防水革的防水性能受多种工艺因素影响,通过探讨染料、复鞣剂、加脂剂、涂饰剂等对防水革的防水性能的影响,进一步优化最佳的防水处理工艺流程及工艺条件。试验结果表明:在pH值6.0左右时防水性能比较好,复鞣剂的使用使皮革的静态吸水率均有所提高,选用无需矿物盐固定剂的防水剂处理皮革,符合环保要求。

Due tothe fact that the waterproofing properties ：of the waterproofing pigskin leathers are affected by the processing influences, the waterproofing processes and conditions have been optimized and chosen through the investigation into the influences of dyestuffs, retanning agents, fatliquors, finishing agents, etc. on the waterproofing properties of the waterproofing leathers. Results show that the waterproofing properties are good when the pH value is about 6.0 and the static water absorption can be increased when retanning agents are used. The environmental protection requirement is reached when leathers are treated with the waterproofing agents without mineral salts fixing agents.
