The invention provides a production technique for high tear-resistance cowhide sofa leather. According to the production technique for the high tear-resistance cowhide sofa leather, the technical problems that an existing processing technique adopts a traditional processing mode, manual work is needed for picking and placing the leather in a reciprocating mode, and processing is complicated are solved. The production technique for the high tear-resistance cowhide sofa leather comprises the following steps that a, preparation of raw materials is conducted, specifically, a leather blank is weighed, firstly, the leather blank is soaked in water for 1-3 h, then, the soaked leather blank is washed with water for 15-20 min, and finally, cleaning liquid is added for cleaning the leather blank for10-16 min; b, water extrusion is conducted, specifically, the leather blank is subjected to water extrusion through a water extrusion device for removing 78%-90% of moisture in the leather blank; c,dyeing is conducted, specifically, the water-extruded leather and a dye solution are put into a dyeing device, and dyeing treatment is conducted for 30-60 min; and d, drying is conducted, specifically, the dyed leather blank is placed in the sun to be sun-dried or baked. The production technique for the high tear-resistance cowhide sofa leather has the advantages of convenient production.
Description
technical field [0001] The invention relates to a production process of high tear-resistant cowhide sofa leather. Background technique [0002] Sofa leather is the main raw material for making leather sofas. It is used to make the surface of sofas. There are many raw materials for sofa leather, including genuine leather sofa leather, PU sofa leather and PVC upper leather. Leather sofa leather generally has cowhide, pigskin, and horsehide. Cowhide is divided into yellow cowhide and buffalo leather, which are divided into first layer, second layer and third layer according to their layers. [0003] After searching, for example, Chinese patent literature discloses a leather processing technology [application number: 201710328616.5; publication number: CN 107012263A]. This leather processing technology is characterized in that the steps are as follows: a. Select a piece of flat leather; b. Depilate the leather surface to make the leather surface smooth and shiny; c. Stretch th...
