Abstract

The invention discloses a preparation method of brown leather, and relates to preparation of leather. The method comprises the following step: S1, changing the color of a crust, processing the crust by using a face-milling machine, placing the processed crust on a full-automatic leather spraying machine to uniformly spray spray-dyeing liquid onto the crust, placing the crust processed by the spray-dyeing liquid inside a washing machine, simultaneously adding a softener and a color fixing agent into the washing machine, processing the crust for 15 minutes in the washing machine, then taking out the crust and placing the crust inside a drying machine to carry out drying on the crust, wherein abrasive paper for processing the crust by the face-milling machine is No. 120 abrasive paper. The leather prepared by the method is more saturated in color and better in comfort, has an archaistic effect, and is unique in color, more natural in color and better in color fixing effect.

Description

[0001] Technical field: [0002] The invention relates to the preparation of leather, in particular to a method for preparing brown leather.
