Abstract

A method for manufacturing corium fiber floss comprises the following steps: firstly, soaking the rim leftover of leather in water and fully expanding the rim leftover, secondly, removing water by dewatering centrifuges, thirdly, hammering the rim leftover into flocculent corium fiber agglomerate through corium cashmere-making machines, then opening the corium fiber agglomerate into corium fiber floss by needle roller opening devices, fourthly, drying, wherein the cashmere-making machines comprise shells, main axle(1)s, hammer carriers (2), hammer (7), bases (9), motors and actuating mechanism. ribs with gear form (5) are distributed on the whole inner-wall of the cylindrical surface of the shell, a plurality of weep holes (10) and a discharge hole are mounted on the lower portion of the cylindrical surface, and a can-be opened-and-closed discharging gate (11) is mounted on the discharge hole. Since the method separates the fiber with each other by hammering the leather after the leather is soaked and expended, then opening the fiber by the needle roller opening device, thereby, the manufacturing time is greatly reduced, the opening forces of opening machines are small, the damage is small, and the high quality corium fiber floss can be obtained.

Description

technical field [0001] The invention relates to a utilization technology of leather leftovers, a manufacturing method of leather fiber cotton and a leather cashmere making machine specially used for manufacturing leather fiber cotton. Background technique [0002] Genuine leather scraps are wastes produced in the production of leather products, and people are exploring how to recycle them. Chinese patent 200510007524.4 "Processing technology of leather fiber fleece and its products" introduces a processing method of leather fiber fleece, adding water, penetrant, slaked lime, softening treasure and sulfur ammonia to the leather scraps, and performing forward and backward in the drum equipment Spin and brush, then dry and fluff to become a genuine leather fiber product. Because this method mainly relies on the rotation of the drum equipment for brushing, it is particularly time-consuming, and a production cycle takes about 77 to 97 hours. The method of making leather into fi...
