Abstract
The invention discloses the process for tanning that a kind of beauty exerts wool fur, concrete technology flow process is as follows：Immersion, fleshing, degreasing, pickling, softening；Also include tanning：Liquor ratio is 1:40, equipment is rotary drum, add the 50g/L of salt 40, water temperature is normal temperature, adds the 3g/L of formic acid 1, adds the 3g/L of sulfuric acid concentration 1, add kind of the 6g/L of stabilizer 3 of organic acid composition, the 12g/L of zirconium aluminium syntans 8 is added after 20 minutes, the 4g/L of sodium formate 2 is added after 6 10 hours, point 2 addition sodium bicarbonate after 30 minutes.Present invention process selection is appropriate, energy-conserving and environment-protective, without using chromium metal tanning, the shrinkage temperature of skin is controlled more than 90 DEG C, can be with direct staining.
Description
Technical field：
The present invention relates to the process for tanning that a kind of beauty exerts woolfell.
Background technology：
Existing import beauty is required for adding chromium during exerting the fur tanning of sheep, if being added without chromium carries out tanning,
The shrinkage temperature of the fur of later stage dyeing is unable to reach 90 DEG C, can only be hovered at 80-85 DEG C or so, if 90 DEG C can not be reached,
Then dyeing cannot realize expected effect, and in existing environmental protection policy, require more and more stricter to the sewage disposal containing chromium,
If not changing technique, it is continuing with chromium to carry out fur tanning, follow-up major part manufacturing enterprise will be difficult to dimension meter, therefore, such as
Where in tanning and dyeing technique without using chromium into urgent need to solve the problem.
The content of the invention：
The technical problems to be solved by the invention are to provide a kind of energy-conserving and environment-protective, and wool is exerted without using the beauty of chromium metal
The process for tanning of skin.
The technical solution of the present invention is to provide the process for tanning that a kind of beauty exerts woolfell, and concrete technology flow process is such as
Under：Immersion, fleshing, degreasing, pickling, softening；
Also include tanning：Liquor ratio is 1:40, equipment is rotary drum, adds salt 40-50g/L, water temperature is normal temperature, adds formic acid 1-
3g/L, adds sulfuric acid concentration 1-3g/L, adds kind of a stabilizer 3-6g/L for organic acid composition, the synthesis of zirconium aluminium is added after 20 minutes
Tanning agent adds sodium formate 2-4g/L after 8-12g/L, 6-10 hours, point 2 addition sodium bicarbonate, 15 points of interval time after 30 minutes
Clock, each concentration 1-2g/L continues to add soda ash, each 30 minutes interval times so that soda ash concentration 2- by several times after 30 minutes
6g/L, adjustment pH to 3.8-4.5 is stayed overnight, next day cleaning, grinds skin, degreasing, and water temperature control is at 40-45 DEG C, 40 minutes time, then
Stuffing.
Further, mill skin uses wet-milling mode.
Present invention process selection is appropriate, has prevented the use of chromium in retanning dyeing process, metal tan is used as using zirconium, aluminium
Agent, makes the shrinkage temperature of skin equally reach more than 90 DEG C, meets coloration requirements, can be with direct staining, and such tanning work makes
Leather is more environmentally friendly, meets environmental requirement, and after dyeing color mixed relative to chromium it is more bright-coloured and Chrome-free, formaldehydeless.
Embodiment：
With reference to embodiment, the invention will be further described：
Embodiment
A kind of beauty exerts the process for tanning of woolfell, and concrete technology flow process is as follows：Immersion, fleshing, degreasing, pickling, softening；
Also include tanning：Liquor ratio is 1:40, equipment is rotary drum, adds salt 40-50g/L, water temperature is normal temperature, adds formic acid 1-
3g/L, adds sulfuric acid concentration 1-3g/L, adds kind of a stabilizer 3-6g/L for organic acid composition, the synthesis of zirconium aluminium is added after 20 minutes
Tanning agent adds sodium formate 2-4g/L after 8-12g/L, 6-10 hours, point 2 addition sodium bicarbonate, 15 points of interval time after 30 minutes
Clock, each concentration 1-2g/L continues to add soda ash, each 30 minutes interval times so that soda ash concentration 2- by several times after 30 minutes
6g/L, adjustment pH to 3.8-4.5 is stayed overnight, next day cleaning, wet-milling, degreasing, and water temperature control is at 40-45 DEG C, 40 minutes time, then
Stuffing.
This technique has abandoned the heavily contaminated mode that traditional handicraft chromium is mixed, and meets existing environmental requirement.Make the contraction temperature of skin
Degree equally reaches more than 90 DEG C, meets coloration requirements, can be with direct staining.
Only preferred embodiments of the present invention are described above, but are not to be construed as limiting the scope of the invention.
