Description

Crocodile skin treatment method

Technical Field

The invention belongs to the technical field of crocodile skin processing, and particularly relates to a crocodile skin processing method.

Background

In recent years, the consumption of high-grade leather products in China becomes a new bright spot in the world, and foreign brands enter China at a glance to seize the market. The crocodile skin product is taken as a leading sheep in the high-grade leather product field, and is more sought after in various aspects. However, both the breeding of crocodiles and the brand construction of crocodile skin products in China start late, the degree of awareness and the reputation are low, and a batch of recognized brands do not exist in the domestic market, so that people are urgently required to master mature tanning technology and establish independent brands. In the actual production process of the crocodile skin, a plurality of technical difficulties need to be broken through, and at the same time, different processes are made according to the differences of the size, the thickness and the like of the crocodile skin, especially in the important processes of liming, bleaching, softening, tanning, retanning, dry cleaning and the like.

The existing reported crocodile skin tanning technology is few, and few independently developed mature processing technologies which can be used for actual production exist, so that the growth and development of special skin processing in China are greatly limited. The alligator breeding and the alligator skin tanning have few relevant literature documents, patents and the like, the only document does not explain the whole tanning process in detail, and a plurality of processes have a plurality of defects. For example, some articles describe the whole wet processing process of crocodile skin, and make some explanations on the aspects of tissue structure, mechanical action, ash and alkali soaking, tanning, finishing and the like, but some specific operations continue to use the processing technology of cow leather, pigskin and sheep skin, and the invention is poor in innovation and practicability and difficult to be used for large-scale production. Some patents also describe novel tanning methods such as enzymatic removal of scale, chrome-free tanning of organic phosphines, etc., which have been considered by practitioners to have certain drawbacks. The application parameters of the enzyme are difficult to control, the components are complex, the damage to the skin fiber is large, and in addition, some special enzymes are developed by a large company, so the cost is higher; the shrinkage temperature of the organic phosphine chrome-free tanned finished leather is too low, and the content of free formaldehyde in the leather exceeds the standard.

However, in the prior art, in the crocodile skin processing method, the transportation processing of the crocodile skin, the grinding processing of the crocodile skin and the oiling processing of the crocodile skin are all realized manually, the grinding and oiling (mainly referred to as maintenance oil) can maintain the good characteristics of the crocodile skin, and the transportation processing is convenient for transferring the crocodile skin from one process to the next process so as to process the crocodile skin at the later stage. Transportation to crocodile skin, polish and oil and all accomplish through the manual work, it is that the manual work is handheld polisher to use to polish to crocodile skin, to oiling of crocodile skin paint oil on crocodile skin on the surface with the brush, still will be in the same direction as the texture on the crocodile skin and neatly reason, but the manual work will be operated each crocodile skin, and intensity of labour is big, and the manual work is polished and can appear inhomogeneous phenomenon with oiling, also can influence post processing like this. In addition, the manual operation labor intensity of the transportation and the processing of the crocodile skin is high, the processing progress is slow, and the large-batch production cannot be met.
