Abstract

The invention belongs to the field of processing of fur, and discloses an environment-friendly fur tanning method. The method comprises the following steps of: soaking the fur, degreasing, pickling, tanning, neutralizing, drying, kicking oil and softening. The materials adopted by the method are in food grade, safe and environment-friendly, and free of pollution; and the prepared fur does not contain heavy metals and formaldehyde, and accords with the environment-friendly requirements. A chemical material is degraded by a biological enzyme preparation, so that the solution of the chemical material and water is continuously used; water resource is not wasted; and the fur prepared by the method is thin and soft, and comfortable in hand handle, and has good elasticity, smoothness and extensibility.

Description

technical field [0001] The invention relates to the technical field of fur processing, in particular to an environment-friendly fur tanning method.
