Study on Vegetable Tanning-Zeolite Tanning Agent Combined Tanning Based on Single Factor Method
To im prove the performance of wet-white obtained from vegetable tannage,the zeolite tanning agent was introduced.The shrinkage temperature and physical properties including tear strength and tensile strength used as evaluation indicators,the best vegetable-zeolite combination tannage process technology was optimized by the single factor method.The experimental results show that the optimal vegetable-zeolite combination tannage process is as follows:the dosage of zeolite tanning agent is 5%,the tanning time is 50 minutes,the tanning endpoint pH is 5.5,and the tanning endpoint temperature is 30℃.The tanning effect of the white-wet obtained by vegetable-zeolite combination tannage process is excellent,with a shrinkage temperature of 94.55℃,a tear strength of 55.75 N/mm,a tensile strength of 11.44 N/mm2,and a significant reduction in positional differences.This has a significant improvement effect on vegetable tanned wet-white,providing a new approach for chrome free combination tanning.
