Patterned leather production technology

Abstract

The invention discloses a patterned leather production technology. The method comprises the following steps: preparing a base cloth; coating two surfaces of the base cloth with mixed liquor of PU resin, a DMF solvent and water, performing pre-solidification to form a primary synthetic material; extruding the primary synthetic material after pre-solidification, drying the synthetic material, and discharging superfluous moisture in the primary synthetic material; coating two surfaces of the base cloth of the primary synthetic material with mixed liquor of PU resin, the DMF solvent, wood powder,calcium carbonate, and a pigment, performing pre-solidification to form the synthetic material; performing steps of rolling, washing, and drying on the synthetic material to form synthetic leather; performing dry kneading on the surface of the synthetic leather by a dry kneading machine; and patterning the surface of the synthetic leather after dry kneading by the dry kneading machine. After coating with the PU resin, the DMF solvent, and the pigment and performing steps of rolling, washing and drying, the synthetic leather is obtained; steps of dry kneading and patterning are carried out on the synthetic leather, and patterns are formed on the surface of the leather, so that the leather is beautiful.

Description

technical field [0001] The invention relates to the field of leather, more specifically, to a production process of patterned leather. Background technique [0002] With the improvement of people's living standards and rich material life, people's requirements for leather fashion and the pursuit of leather products are becoming more and more prominent, not only in terms of color, color and leather, but also in terms of energy conservation and environmental protection. There are also higher requirements, and the current market demand for leather post-processing products such as leather printing is also increasing. But the existing pattern leather production technology is comparatively complicated, and production efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pattern leather production process aiming at the above defects of the prior art. [0004] The technical scheme adopted by the present ...
