Method for making book-binding leather from rabbit skin and book-binding leather made according to method

Abstract

The invention provides a method for making book-binding leather from rabbit skin. According to the method, preservative-treated rabbit skin or fresh rabbit skin is soaked in water and subjected to meat removal to obtain a rabbit skin blank as a raw material. The method comprises the following steps: (1) liming and depilation, (2) deliming, (3) pickling, (4) tanning, and (5) retanning, finishing and coating. The method provided by the invention provides a new way of utilization of rabbit skin, provides a reasonable way of effective and reasonable utilization of rabbit skin, especially low-end and defective rabbit skin, and can reduce the waste of rabbit skin resources and avoid environmental pollution caused by abandonment of low-end and defective rabbit skin. The invention further provides book-binding leather made from rabbit skin according to the method, the book-binding leather made from rabbit skin has full dermatome and flat and fine grain, has no obvious location difference, and cannot suffer from the problem of loose grain easily during the making and using process.

Description

technical field [0001] The invention belongs to the field of written leather processing, in particular to a method for making written leather from rabbit skin and the prepared written leather. Background technique [0002] Written leather refers to a kind of leather used to cover written or notebook covers. Written leather has good plasticity and is convenient for embossing patterns and characters on the leather surface. It is used as a high-grade hardcover book cover to protect and beautify books. And show its preciousness. Existing written leather is usually made through vegetable tanning by yellow cowhide, buffalo hide, goatskin, and pigskin. [0003] Yellow cowhide is expensive and rarely used to make written leather. Buffalo leather is often used instead of yellow cowhide to make written leather. The grain of buffalo leather is rough, and the thickness of the skin varies greatly. 3mm, the skin thickness ratio of the abdomen to the buttocks is about 1: (2.2-2.9), speci...

AI Technical Summary

Problems solved by technology

As a raw material for fur, rabbit skin is of relatively low fur-making value because of its long guard hair, low wool fiber strength, easy to break, and relatively hollow fluff.

There are still seasonal differences in the quality of rabbit skins. In winter and spring, rabbit skins are valuable for making furs. In summer and autumn, due to reasons such as moulting, shedding and part of the hairs of rabbits are in a dormant state, rabbit skins The fur is very sparse, not firmly rooted, and easy to fall off. The value of making fur is extremely low, and it is difficult to use, resulting in a large number of rabbit skins that cannot be effectively used.

In recent years, with the increasing demand for rabbit meat, the breeding volume of domestic rabbits has also continued to increase. However, the breeding period of this type of domestic rabbits that provide rabbit meat is often very short, and the adhesion fastness between the fur of the rabbit skin and the leather board is low. It is also difficult to be used for making furs, so a large amount of low-grade rabbit skins with extremely low fur value have been produced. This kind of rabbit skins is difficult to be used for furs and can only be discarded, which not only wastes resources, but also pollutes the environment.

There is no report on making written leather with rabbit skin as raw material at present. Eliminating the problems of poor parts and loose surfaces will have positive significance for the rational use of rabbit skins with low fur-making value, enriching the types of writing leather and improving the quality of writing leather
