Dispersing Agent NNO used in Leather Industry

Dispersing Agent NNO as a pre-tanning agent in leather processing, which can make filling and soft. As auxiliary tanning agent in leather industry, used together with tanning agent to avoid tanning agent stick on with leather.

The application of surfactants in the tanning process is that they can accelerate the penetration of tanning agents and slow down the combination, so as to achieve the purpose of fast tanning and uniform tanning. In the modern blue leather process, pre-tanning with cationic oil can promote the penetration of chrome. The tanned leather does not have a blue heart, and can obtain plump, soft, and fine-grained leather. During the tanning process, adding 0.5% of the Dispersing agent NNO while adding chrome liquid can shorten the tanning time; because Dispersing Agent NNO is a weak alkaline substance, it has a slight alkalinity effect, which is conducive to the combination of chrome and fiber. If polyethylene glycol dodecyl ether or polyethylene glycol nonylphenol ether is added during chrome tanning, the binding amount of chrome can be increased, making the leather feel full.
