Abstract

The invention belongs to the production technical field of elastic leather products, and discloses a processing technology for fattening sheep elastic leather products, comprising the following steps: 1) backwatering the elastic leather wet blue; 2) retanning; 3) fatliquoring; 4 ) standing, squeezing water, hanging to dry; 5) spraying water on the surface of the board, standing still, breaking soft, and trimming; 6) adhesive: using a through-type adhesive machine to bond the wet blue leather and the base cloth; 7) putting on a horse ; 8) Backwater; 9) Second-layer surface dyeing; 10) Mounting, spraying water on the surface of the board, standing still; 11) Breaking soft, finishing. The processing technology of the present invention can effectively solve the problems of poor quality and high cost of making elastic leather for fattening sheep. The process is economical and environmentally friendly, and the strength and uniformity of the leather body are improved. At the same time, the utilization rate of the second layer after the sheet is high, and the economic benefit and environmental protection Significant benefits.

Description

technical field [0001] The invention belongs to the production technical field of elastic leather products, and in particular relates to a processing technology for fattening sheep elastic leather products. Background technique [0002] Regarding the production of elastic leather clothing products, there are two main problems at present: ①The fattening sheep has a large difference in position, the middle spine is thick and tight, and the side belly is loose, while the elastic leather requires uniform thickness, which is mostly kept at 0.2mm. On a light and thin basis, it is necessary to maintain high elasticity, which brings great challenges to the retanning process in the water field. Retanning must be used to improve the uniformity and strength of the leather body; ②The processing cost is high, and the general fattening sheep elastic leather, although Raw hides are cheap, but only the surface grain is available. Flakes or wet or dry shaves will damage the second layer of l...
