Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with specific embodiments.

[0023] Firstly, the mink skins are divided into batches, peeled and fleshed to obtain pure mink skins, and then soaked in water, degreased and re-soaked in water, softened and pickled and tanned according to the following procedures respectively.

[0024] 1. Soaking process: Prepare the soaking solution according to the process conditions, paddle it evenly, and cast the skin.

[0025] Wherein, the technological condition of soaking process is:

[0026] a), using equipment: pool or trough

[0027] b), liquid ratio: 2 (wet skin mass meter)

[0028] c), chemical raw material formula:

[0029] Salt: 25g / L;

[0030] Soaking enzyme 100-c: 1g / L

[0031] d), time: 2-3 hours

[0032] e) Temperature: 25°C

[0033] This water soaking process uses water soaking enzyme 100-c to dissolve the protein between the hide fibers and make the hide soft. Compared with the tradi...
