Technical field:
The present invention relates to leather and fur and make field, be especially the taw technique of a kind of fox rawhide fur coat.
Background technology:
In prior art, for shortened process, mostly use formaldehyde, aromatic, it is impossible to meet energy-conservation subtracting The requirement of row, water consumption is big, not only adds cost but also waste water resource.
Summary of the invention:
The technical problem to be solved is to provide the taw of the fox rawhide fur coat of a kind of energy-conserving and environment-protective 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；
11st step, pickling softens, and skin is steeped the reuse pickling less than 1 week and softens in collection water, heat To 35 DEG C, add salt, formic acid, oils and fats dispersant and fatting agent, acidicenzym, to pH value 2.5-2.6, mistake Going out skin control water after night, draining to pickling softens in water collecting pit；
12nd step, tanning, skin to be steeped in the reuse tanning water less than 1 week, temperature controls at 33-35 DEG C, Adding salt, modified aldehyde tanning agent, penetrating agent, soda, to pH value 7.5-8.0, go out skin the most afterwards, draining is arrived Tanning water collecting pit；
13rd step, frizzled feather, dermatotome skin frizzled feather outwardly outwardly；
14th step, scouring of wool, skin is put in the clear water of 40 DEG C, add degreasing agent, after 2 hours, go out skin row Water is to washing severe edema due to hypofunction of the spleen collecting pit；
15th step, rinsing, skin is steeped in the warm water of 30-35 DEG C, turn, stop 30 minutes, go out skin draining To defat water collecting pit；
16th step, arctic fox brightens, and arctic fox skin being steeped collection is brightened in collection water, is warmed to 40 DEG C, Supplement after surveying salinity and add ammonia-alum, aluminium tanningagent, auxiliary tanning agent, brightening agent, penetrating agent, adjust pH value and arrive 3.5-3.6, goes out skin, and water collecting pit is brightened in draining to arctic fox；
17th step, blue Vulpes increases indigo plant, and blue Vulpes skin being steeped collection increases blue collection in water, is warmed to 40 DEG C, Survey salinity, if salinity is less than 3 Baumes, add ammonia-alum, aluminium tanningagent, auxiliary tanning agent, penetrating agent, to pH value To 3.5-3.6, going out skin the most afterwards and dry, drainage collection increases indigo plant to blue Vulpes and collects pond；
18th step, stuffing, be dried.
