retanning

If it used with various retanning agents, the fullness of leather was good.

This paper introduces the synthesis, applied technology and properties of amphoteric polyurethane retanning agent UT .

It was developed retanning , dyeing, fatliquoring, dressing and coating technologies matched to enzyme techniques.

Its using properties were studied in this paper through the application in retanning pigskin garment splits.

One new retanning agent was synthesized by adipic acid, diethyenetriamine, epichlorohydrin, phenol, and formaldehyde.

The results showed that the new type retanning agent had good filling and auxiliary dyeing action to leather.

Acrylic resin was extensively used as retanning agent, filling agent and finishing agent in the leather industry.

In this paper, the applications of several retanning agents on goatskin garment leathers are discussed.

Retanning with suitable acrylic resin could improve the strength of the split.

The drum is the cornerstone of modern tannery machines for tanning , retanning and dyeing .

It is important to strengthen the research of preparation and its property of amine resin retanning agent.

Three brands of chrome containing polyacrylate retanning agent(CCPRA) were utilized to pretan chrome leather.
