Composite enzyme preparation for fur degreasing and preparation method thereof

Abstract

The invention relates to the field of animal fur treatment process, in particular to a composite enzyme preparation for fur degreasing and a preparation method thereof. The composite enzyme preparation for fur degreasing is mainly composed of, by weight, 1-6 parts of proenzyme, 5-30 parts of activator, 1-10 parts of stabilizer, 5-20 parts of slow-release agent and 30-100 parts of filler, wherein the proenzyme is selected from neutral lipase and trypsin, and the slow-release agent is a water-soluble organosilicon polymer. The composite enzyme preparation for fur degreasing is simple and feasible in preparation method, synergistic effect among all the components is achieved, so that the obtained composite enzyme preparation for fur degreasing has excellent grease decomposition performance; when the composite enzyme preparation for fur degreasing is used for rawhide degreasing, the degreasing effect is better than the degreasing effect of a traditional degreasing agent, the degreasing is more uniform and thorough, the degreasing effect is mild, and no harm is caused to the fur; and meanwhile, the use of a surfactant can be reduced or eliminated by using the enzyme to degrease, and the composite enzyme preparation belongs to an environment-friendly product.

Description

technical field [0001] The invention relates to the field of animal fur treatment technology, in particular to a fur degreasing composite enzyme preparation and a preparation method thereof. Background technique [0002] Degreasing is one of the main processes in fur production, especially in the production of fatty skins. Its purpose is to remove the oil and fat in the fur and create conditions for the infiltration and combination of chemical materials in the subsequent process. If the raw skin is not degreased cleanly, it will hinder the penetration and action of other chemicals, affect the brightness and uniformity of dyeing, and cause the fur to produce greasy frost. For raw hides containing more fat, degreasing is often carried out separately during the wet processing process. Traditional degreasing methods mainly use alkali to saponify and wash fat, or use surfactants to emulsify and disperse fat to remove it. [0003] In recent years, due to the requirements of envi...

AI Technical Summary

Problems solved by technology

[0004] At present, there are enzyme preparations specially used for degreasing in the market, and they are mostly used on leather. It is not mature for fur degreasing because enzyme degreasing belongs to surface degreasing, and its permeability is not good, and it must not shed hair.
