Abstract

Abstract: A chromium-free tanning agent was synthesized by means of mechanical force activation in anhydrous state using cyanuric chloride as raw material and p-aminobenzenesulfonic acid as graft modifier. The grafted structure of the tanning agent was characterized, and the synthesis process and product structure of the tanning agent were analyzed. The tanning property of the tanning agent was tested, and it was found that the synthetic product exhibited tanning property. When the tanning agent was used in combination with catechin, the resulting leather exhibited the soft and plump performance, and good strength. Therefore, the tanning agent is expected to be used as a chrome-free tanning agent for production of wet white.

Key words: cyanuric chloride, dry-state reaction, chrome-free tanning
