Abstract
In this paper, the collagen was hydrolyzed with NaOH to get hydrolyzed collagen, and then the hydrolyzed collagen was modified with glyoxal acid and acrylic acid. After separated and purified with absolute ethyl alcohol and acetone, the chrome tanning auxiliary agent was obtained, the optimum dosage of glyoxal was Discussed and application was experimented by tannage of a goat skin with chrome agent and the produced auxiliary agent. Temperature of shrinkage was determined and the chrome content of the solution was analyzed by inductively coupled plasma atomic emission spectroscopy (ICP) to adjust the tanning procedure to get a best result. Through the experiment we get the following conclusions; the optimum dosage of glyoxal is 8% in the synthesize process. The grafted rate of the auxiliary agent is 23. 50%. After application experiment with the auxiliary agent, we found with 4% dosage of the auxiliary agent, the chrome content of the tanning solution was 18. 2% lower than the auxiliary agent free tanned solution. The Ts of the leather tanned with the auxiliary agent was also 7.2℃ higher than the auxiliary agent free tanned solution.关键词
