Anti-static anti-bacterial chitosan-casein composite leather finishing agent and preparation method thereof

Abstract

The invention provides a preparation method of an anti-static anti-bacterial chitosan-casein composite leather finishing agent. The preparation method of the anti-static anti-bacterial chitosan-caseincomposite leather finishing agent includes the following steps of 1, dissolving chitosan; 2, dissolving casein; 3, preparing the anti-static anti-bacterial chitosan-casein composite leather finishingagent. Raw materials adopted in the preparation method are biodegradable; a composite technology is adopted, so that the preparation method is simple, the stability of products is good, the preparedanti-static anti-bacterial chitosan-casein composite leather finishing agent is a natural-product-based leather finishing agent with two functions of preventing static and bacteria.

Description

technical field

[0001] The invention belongs to the technical field, and relates to an antistatic and antibacterial chitosan-casein composite leather finishing agent and a preparation method thereof. Background technique
