Abstract

The invention provides a manufacturing method of sofa leather, and solves the technical problems of more complicated steps, need of spending a lot of manufacturing time, complicated manufacturing andthe like in a traditional manufacturing method. The manufacturing method of the sofa leather comprises the following steps: (a) a leather blank is flatly paved on a passing water extruder to for waterextrusion to remove 78-96% of water in the leather blank; (b) the leather blank is dried through a drying device; (c) a repair agent is coated on the leather blank; (d) the leather blank is polishedthrough a leather polishing machine; (e) the leather blank is sized through a roller coating device; (f) paint is sprayed to the leather blank through a spraying device to obtain leather; (g) the leather is embossed or printed by two modes of knurling and plate pressing; (h) fall softening or pull softening is performed by a pull softening machine and a fall softening rotating drum; (i) the leather is ironed through high temperature to obtain finished sofa leather; and (j) the leather is measured, detected and warehoused. The manufacturing method of the sofa leather has the advantage of convenience to manufacture.

Description

technical field [0001] The invention relates to a method for making sofa leather.
