漂白含铬合成鞣剂的组成结构与鞣制革坯的漂白、耐光性

The relationship between componsition of white tanning agent with chromium oxide and bleaching & lightfast

1.前言世界皮革工业的潮流,正朝着轻、薄、软发展。对革的质量、花色,在柔软、丰满、弹性好以及漂白、耐光等提出了更高的要求。芳香类高分子化合物作为鞣剂、复鞣剂仍占据着重要地位。芳香型漂白含铬合成鞣剂的组成,包括铬和合成树脂两部份,其鞣革特征既取决于芳烃的磺化性状和基础树脂的组成结构,又受铬化物特性所制约。

In the paper, the relationship between composition of the white tanning agent with chromium Oxide and bleaching & Lightfast for wet blue. These results shown that bleaching and Lightfastness of synthetic tanning agent depend to a longe on composition of polymer, but the colour of Leather would be disturbed by chrome content as an off colour.
