摘要
为了提高TWS鞣制白湿革的收缩温度及物理力学性能,以沸石鞣剂用量、转动时间、中和pH、固定温度为影响因素,以坯革收缩温度、力学性能为考察指标,设计正交试验方案,进行植物-沸石结合复鞣工艺优化试验.结果表明:沸石鞣剂用量对收缩温度具有决定性影响,转动时间对抗张强度和崩破强度的影响最大,中和pH对撕裂强度的影响最大;最佳工艺参数为:BS用量5％,转动时间3小时,中和pH 5.5,固定温度30℃,所得坯革收缩温度89.5 ℃,撕裂强度75.00 N·mm-1,抗张强度11.53N·mm-2,崩破强度205.69 N·mm-1.实验对无铬生态皮革的复鞣工艺设计具有重要参考意义.
Abstract
In order to improve the shrinkage temperature and physical and mechanical properties of TWS tanning white wet leather,the amount of zeolite tanning agent,the rotation time,the neutralize pH and the fixing temperature were taken as the influencing factors,the shrinkage temperature and mechanical properties of leather crust were investigated.The orthogonal test was designed to optimize the retanning process with vegetable-zeolite combination.The results showed that:the amount of zeolite tanning agent had a decisive effect on the shrinkage temperature,the rotation time had the greatest effect on the tensile strength and the bursting strength,and the pH had the greatest effect on the tearing strength.The optimum process parameters were as follows:5％BS,3 hours rotating time,pH 5.5,30℃ fixed temperature,yielding leather with a shrinkage temperature threshold of 89.5 ℃,a tear resistance of 75.00 N·mm-1,a tensile strength of 11.53 N·mm-2,and a burst strength or bursting strength of 205.69 N·mm-1.It has important reference significance for the retanning process design of chrome-free ecological leather.
