Abstract

The invention discloses a preparation process for sofa leather. According to the preparation process, a series of processes of curing, soaking, fleshing, degreasing, depilating, tanning, acid-alkali treatment, extrusion flattening, drying and milling, dyeing, coating and embossing are adopted, so that fur is made into a sofa leather body; curing of the fur is used for killing microorganisms and bacteria on the surface of the fur, so that the fur is guaranteed to be prevented from going bad in the processing process; soaking of the fur is used for enabling the fur to regain water lost in the curing process; a hair removal enzyme inhibitor is utilized to prevent the hair removal enzyme from damaging a fur body during the hair removal process; the substance state of the sofa leather is adjusted by means of acid-alkali treatment, so that the sofa leather is better colored; and the preparation process has the advantages that the process is strictly controlled, industrial production can be realized, the fur is guaranteed to be prevented from going bad in the fur processing process, resource waste is avoided, cost is saved, preparation time of the sofa leather is shortened, and the factory income is improved.
