具有复鞣和固色功能的复合鞣剂

Compound tanning agents possessing retanning aud colorfast function

本文研究一种具有复鞣和固色性能的合成鞣剂。它由芳烃及其含氧衍生物经磺化、缩合,与Cr-Al多金属络合物复合而成。文中阐述了磺化,羟甲基化的深度,鞣剂的相对粘度,电解质的加入对鞣剂性能的影响,探讨了鞣剂中某种有机与无机组分对革染色的固色作用。

This paper reportes a novel compound tanning agent possessing retanning andcolorfast functions.This agent was synthesized with aromatic hydrocarbon and phenolicderivatives,by the ways of sulfonating,condensing and reacung with the Cr-Al complex.The affect of sulphofication and hydroxymethylation extem,the re(?)aue viscosity of tan-ning agent and the added NaCl to the properties or the resu(?)ed agent are discussed heretoo.This paper also presents the colorfast functions from some orga(?)e or inorganic com-pounds in the tanning agent.
