Abstract

The invention provides a processing technology of chromium composited tan cutting broad woolskin, relating to the manufacturing of sheep shearing in shearling industry, in particular to the processing technology of the chromium composited tan cutting broad woolskin. The processing technology adopts specific pickling and lipase adding technology conditions, pretanning technology conditions, compound tanning technology conditions and dyeing technology conditions, thereby overcoming the defects that all physicochemical indexes of products in the prior art, such as hexavalent chromlum content, free formaldehyde content, harmful aromatic amine content and other harmful substance contents as well as color fastness index, are not effectively solved. The technology of the invention pursues beautiful appearance of products and pays attention to inherent quality and human health increasingly; and especially, three hazards contents reach departmental standards, thus the invention becomes a processing technology of sheep shearing products which is green ecological, healthy and no harmful effect on customers.

Description

technical field [0001] The invention relates to the production of sheared sheepskin in the wool and sheepskin industry, in particular to a processing technology of chrome compound tanned sheared shearling straight wool sheepskin. Background technique [0002] At present, the traditional pure chrome tanning or pure formaldehyde tanning method has been used in the tanning of domestic sheep shearing products. Although the sensory indicators can basically meet the requirements of customers, whether the physical and chemical indicators can meet the standards has been ignored by people, especially for domestic products. In recent years, some textile products and fur products exported to Europe and the United States have been detected to have excessive levels of hexavalent chromium, free formaldehyde, and harmful aromatic amines, making the traditional tanning process unable to meet export requirements. In China, with the continuous development of social economy and the improvement...
