摘要： A process for the p reparation of a synthetic tanning a gent is disclosed whereby multi functional polymer is polymerized with sulfonated aromatic compound, pretreated with organic ligand to form an organo-polymeric matrix, free from formaldehyde. The product has potential application in leather industry for not only ensuring an eco-friendly approach in chrome tanning by way of eliminating the conventional pickling process and the resulting problem of total dissolved solids (TDS) associated with the effluent, but also suggesting an exhaust aid for chrome because of its multiple carboxyl groups. The product can also be used as a retanning agent in leather processing.

摘要： The present invention relates to a leather process whereby the post tanning wet operations are done prior to tanning stage itself to make leather in ecofriendly manner in substantially shorter duration. It is envisaged to have enormous potential application in leather industry for making leathers with comparable sofness and grain smoothness, whereby the pollution load would be significantly less compared to that of the conventional leather processing.
摘要翻译： 本发明涉及一种皮革加工方法，其中在鞣制阶段之前完成鞣后湿法操作以在短得多的持续时间内以环保方式制造皮革。 预计在皮革工业中用于制造具有可比较的柔软度和平滑度的皮革具有巨大的潜在应用，因此与常规皮革加工相比，污染负荷将明显更小。
