Technique.
The technical solution of the present invention is to provide the taw technique of a kind of fox rawhide fur coat, and it includes
Following steps:
The first step, gage, refer to the nose length to root of the tail, determine liquefaction coefficient by specification;
Second step, washes skin, hair skin outwardly is steeped the reuse skin of washing less than two days and collects in water, salt adding,
Salinity is 2 Baumes, adds degreasing agent, penetrating agent, and then temperature is to 25 DEG C, soaks more than 4 hours, goes out skin row
Water is to treatment tank;
3rd step, water dumping, leather jacket is entered centrifugal dehydrator transfer 5 minutes, goes out skin;
4th step, turnover panel, hair skin skull patch plate outwardly outwardly;
5th step, chops off the ears, and removes with hilt ear internal layer cartilage, keeps ear outer layer shape complete;
6th step, dise knife, use disk shaving machine, the fat that shaving head, ridge and afterbody are thick;
The fat that 7th step, deburring, the corner stayed with cutter shaving and afterbody are unnecessary;
8th step, fleshing, draw whole body by the water shovel equipped with return pipe water, it is important that back, head and afterbody,
Return pipe water emptied discharge the same day;
9th step, defat, skin put into collect defat water in, heat 40 DEG C, add soda, degreasing agent,
Penetrating agent, oils and fats dispersant, antibacterial, go out skin water dumping 15 minutes after 3 hours, draining is to treatment tank;
Tenth step, cleans, skin is steeped in water, is warmed to 35 DEG C, turns, stops 30 minutes, goes out skin, controls water,
Draining washes severe edema due to hypofunction of the spleen pond to collection;
