Embodiment Construction

[0015] The embodiment thereof will be described in detail below.

[0016] This kind of leather fiber velvet processing technology includes the following steps: material selection, color separation and cutting of leather leftovers; selection of leather trimmings with a weight ratio of 100 parts, the addition temperature is 38°C-45°C, and the weight ratio is 200 ~250 parts of water, at the same time add 1.5~2 parts of penetrant JFC, put it into the drum equipment and rotate it clockwise continuously for 60~90 minutes, then rotate it counterclockwise for 10 minutes, and seal it for 20~24 hours , and then; adding the sealed mixture into water with a weight ratio of 50 parts at a temperature of 38°C-45°C, and adding slaked lime at a weight ratio of 5 to 6 parts at the same time, and continuously rotating the brushing in the drum equipment for 120 minutes. Seal for 35-40 hours; at this time, the PH value of the mixture liquid is 11-12, put the above-mentioned mixture back into the d...

Abstract

A processing technology of leather fiber fleece, its main feature is to select, color-separate and trim the leftover leather materials in different periods and add the required water, penetrant, slaked lime, softening treasure and ammonium sulfate in the drum equipment. Reverse-rotate brushing, dry and fluff the leather fiber fleece to become a leather fiber product, the fiber length of which is not less than 16 mm. The invention recycles the leftovers of the leather fiber into the leather fiber fleece through a scientific processing technology, so as to make the leather fiber fleece Fiber fleece is woven into cloth to meet the needs of industry and life.

Description

【Technical field】 [0001] The invention relates to the processing technology of leather fiber fleece, in particular to the invention of the processing technology of leather fiber fleece. 【Background technique】 [0002] In the prior art, after leather processing, there are many leftover materials that cannot be recycled, resulting in a major loss of leather resources. How to maximize the use of animal leather leftovers to reduce or overcome waste is still a problem that leather engineers and technicians have been studying. unresolved issues. 【Content of invention】 [0003] In view of the existing problems of the known technology, the technical problem to be solved by the present invention is to recycle and process the leather leftovers into fiber fleece for spinning and weaving, so as to be applied in industry and life, and to achieve a rational allocation of resources. In order to achieve the above object, the present invention adopts following process to finish: a kind of...
