Abstract

The invention provides a method for treating leather leftover materials. The method solves the technical problems of complexity, excessive processes and poor treatment effects of existing methods. Themethod for treating the leather leftover materials comprises the following steps of S1, preparing the leather leftover materials, removing impurities, then conducting screening and sorting, and saving the obtained materials as standby materials; S2, placing the standby materials in S1 into a crushing mechanism of a beating system to obtain short-fiber-shaped standby materials; S3, placing the short-fiber-shaped standby materials in S2 into a cleaning liquid for soaking treatment, conducting heating to raise the temperature to 30-50 DEG C, and conducting heat preservation for 2-3 h; S4, placing the soaked standby materials in S3 into a beating barrel of the beating system, conducting grinding for 15-30 min to obtain fine-fiber-shaped initial slurry, and then placing treatment liquid into the beating barrel of the beating system to obtain finished slurry. The method has the advantage that the treatment effect is good.

Description

technical field [0001] The invention relates to a processing method, in particular to a processing method for leftover leather. Background technique [0002] Leather scraps are wastes that are inevitably produced in the production process of leather products, and leather is mainly composed of bundle-type and micro-bundle-type collagen fibers that are interwoven and intertwined. [0003] After searching, for example, Chinese patent literature discloses a method for preparing kraft fiber yarn from cowhide scraps [application number: CN201110146644.8; publication number: CN102212914B]. The method for producing kraft fiber yarn from cowhide scraps comprises the following steps: sequentially screening the cowhide scraps, color separation, removing impurities, puffing and softening, extruding, repeated soaking and extruding, hammering to make cashmere, finishing, drawing After loosening and drying, kraft fibers with a length of 15-50mm and a fineness of 0.5D-2.2D are obtained, an...
