Embodiment 1

[0035] A process for tanning and dyeing mink fur with both fur and leather, the process comprises the following steps:

[0036] (1) Selection and pretreatment of raw hides; select mink skins that are mature and disease-free on the surface in that year, sort the raw hides, split them, and cut them into pieces, and then use a pretreatment agent for pretreatment. The pretreatment agent consists of pretreatment agent A Form with pretreatment agent B, pretreatment agent A is the reduced glutathione aqueous solution of mass fraction 1.5%, and pretreatment agent B is the water-soluble dextran aqueous solution of mass fraction 8%, and described pretreatment operation condition is as follows: At room temperature, first soak and pretreat with pretreatment agent A for 3-5 hours, then drain and immediately soak and pretreat with pretreatment agent B for 1-2 hours;

[0037] (2) Soak the rawhide in water, return to freshness, remove oil and remove flesh: put the rawhide pretreated in step (...

Embodiment 2

[0049] A process for tanning and dyeing mink fur with both fur and leather, the process comprises the following steps:

[0050] (1) Selection and pretreatment of raw hides; select mink skins that are mature and disease-free on the surface in that year, sort the raw hides, split them, and cut them into pieces, and then use a pretreatment agent for pretreatment. The pretreatment agent consists of pretreatment agent A Form with pretreatment agent B, pretreatment agent A is the reduced glutathione aqueous solution of mass fraction 2.0%, pretreatment agent B is the water-soluble dextran aqueous solution of mass fraction 5%, described pretreatment operation condition is as follows: At room temperature, mix pretreatment agent A and pretreatment agent B evenly at a volume ratio of 1-2:1, and then soak in raw hides for 3-4 hours;

[0051] (2) Soak the rawhide in water, return to freshness, remove oil and remove flesh: put the rawhide pretreated in step (1) in water at a temperature of ...

Abstract

The invention relates to a processing technique of animal fur, in particular to a tanning and dyeing technique of mink skin with functions as fur and leather. The technique comprises the following steps of (1) green hide selection and pre-processing, (2) water soaking, freshness recovery, oil removal and grease removal of green hide, (3) nitrate leaching and degreasing, (4) pickling and softening, (5) aluminum tanning, (6) neutralizing, (7) oil tanning, (8) dry cleaning, milling of leather and arranging, (9) chrome tanning, and (10) buffing and dyeing. According to the technique, the design is reasonable, reasonable pre-processing is conducted on the green hide, the quality of the green hide is improved, the subsequent processing technique is simplified, the number of varieties of reagents used for the technique is decreased, the processing cost is low, the production efficiency is high, the quality of finished mink skin is high, the coat color is bright, and the fur is smooth.

Description

technical field [0001] The invention relates to a processing technology of animal fur, in particular to a process for tanning and dyeing mink skin with both fur and leather functions. Background technique [0002] Mink fur is mostly made into high-grade fur products, especially mink fur which has the advantages of both otter fur and sable. Precious fine fur, known as the "King of Fur", has become the first of the three pillars of the international fur market (mink, Persian lamb, and blue fox). [0003] At present, chrome tanning, aluminum tanning, and tanning methods are mostly used for fur tanning at home and abroad. The skins produced by this method often have disadvantages such as stiff skin boards. In order to improve the grade of fur, during the tanning process of mink, pickling , softening, tanning and degreasing and other general processes to be improved. Mink fur is solid and thick, with well-developed elastic fibers in the cortex. The difference between the back a...
