Embodiment Construction

[0013] The following ratios of raw materials are weight ratios.

[0014] After dry finishing, the leather goes through the following processing steps in sequence:

[0015] 1. Sealing leather: the raw materials used are: polyurethane 100, water 300.

[0016] 2. Back cover: Anionic resin FI-17-701 (an emulsion of water-soluble cationic wax, which promotes the penetration of chemicals and facilitates the combination of leather and chemicals, produced by STAHL): 80, wax FI-50 (wax agent, water-soluble Emulsion of wax, prevents sticking to the board, has good release property, produced by STAHL company): 50, water 150. After 2 hours of aging, iron it, break it soft, and stretch the board.

[0017] 3. Spray the bottom layer: pigment paste 100, water 150, wax FI-50: 50, resin film-forming agent SP-32-114 (composite resin, modified acrylic acid copolymer emulsion, make the chemical material into a film, combine the skin with the pigment Better, produced for STAHL company): 300, ant...

Abstract

The fabrication process of multi-color fancy leather includes the following steps: after lining sealing, bottom sealing and bottom injection, a piece of dry-finished leather receives swabbing treatment, i.e. according to templet patterns, different patterns are swabbed on the surface of the leather by means of pigments through adopting a piece of soft cloth so as to create the basic frame of the patterns; after drying, a user can use the soft cloth to swab the pigments on the leather surface evenly and mends threadbare and damaged parts during even swabbing; then, swabbing treatment is carried out again to strengthen the effect of the first swabbing treatment; finally, effect layer spray painting is completed. In addition, according to weight proportion, the pigments comprise transparent pigment paste 80, water 100, wax 30, antisticking agent 20, casein 50 and film former 200 and are dried for final fixation. The invention changes the status quo that leather is only of single color and double color and obtains the combining effect of three or more colors, thereby being flexible; meanwhile, the leather made through adopting the invention has stereoscopic impression and higher color transparency and satiation degree; moreover, the invention obtains great improvement in overall utilization rate and grade of leather and increases the colors of leather.

Description

technical field [0001] The invention belongs to the field of leather processing and production, and in particular relates to a production process of multi-color artistic leather. Background technique [0002] The current leather production is basically all single-color and double-color, with poor transparency, not bright enough color, and a single fixed pattern. In addition, some hides are disabled and have small water erosion eyes, which affect the overall utilization rate of the hides. With the improvement of people's living standards and aesthetics, traditional leather can no longer meet the needs of consumers. In this case, it is urgent to produce leather products with natural luster, strong transparency, and variety. Manual treatment can repair the disabled and water-eroded eye parts, and improve the utilization rate of leather. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-color artistic leather ...
