Problems solved by technology

First of all, the amount of kicking oil used in this method is relatively large, and the price of the kicking oil is very expensive, resulting in high tanning costs; secondly, the kicking oil is a mixture of natural oils and synthetic oils, and the kicking oil is mainly used to physically wrap the skin during tanning. Board fiber, this combination is not stable enough, and the tanning effect needs to be improved

Embodiment 1

[0028] The present embodiment adopts the method for tanning lambskin of the present invention, and the processing steps are as follows:

[0029] (1) Carry out meat removal, water soaking, degreasing, softening and pickling treatment on the lamb skin according to the conventional process. When the pickling treatment is completed, the pH value of the pickling solution is 2.3. When the water content of the lamb skin is 30wt%, the pickled lamb skin is obtained.

[0030] (2) Add 500kg of water and 25kg of sodium chloride into the trough, swipe the scribing board to dissolve the sodium chloride completely, and then add the pickled lamb skin obtained in step (1) under the condition of sliding the scribing board Blank 100kg, paddle for 5 minutes, then add 1.0 kg of fatty aldehyde tanning agent FB under the condition of padding, paddle for 30 min, continue to add sodium bicarbonate in 3 times under the condition of padding (Every interval of 15 minutes) Adjust the pH value of the mixe...

[0039] The present embodiment adopts the method for tanning meat rabbit skin of the present invention, and the processing steps are as follows:

[0040] (1) Carry out fleshing, soaking, degreasing, softening, and pickling treatment on the meat rabbit skin according to the conventional process. When the pickling treatment is completed, the pH value of the pickling solution is 2.5. water until the water content of the meat rabbit skin base is 30wt%, and then the pickled meat rabbit skin base is obtained.

[0041] (2) Add 300kg of water and 15kg of sodium chloride into the groove, stroke the blade of the groove to dissolve the sodium chloride completely, and then add the pickled meat rabbit skin obtained in step (1) under the condition of stroke the blade Leather 100kg, paddle for 10 minutes, then add fatty aldehyde tanning agent FB1.0kg under the condition of paddle, paddle for 10 min, continue to add bicarbonate in 3 times under the condition of paddle Sodium (every interval o...

Embodiment 3

[0050] Present embodiment adopts the method for tanning rex rabbit skin of the present invention, and process step is as follows:

[0051] (1) Carry out the fleshing, soaking, degreasing, softening, and pickling treatment of the rex rabbit skin according to the conventional process. When the pickling treatment is completed, the pH value of the pickling solution is 2.5, and the pickling-treated rex rabbit skin is taken out and dripped with water Until the water content of the rex rabbit skin is 40wt%, the pickled rex rabbit skin is obtained.

[0052] (2) Add 400kg of water and 20kg of sodium chloride into the trough, swipe the scribing board to dissolve the sodium chloride completely, and then add the pickled rex rabbit skin obtained in step (1) under the condition of sliding the scribing board Blank 100kg, paddle the board for 10 minutes, then add 1.2 kg of glyoxal under the condition of paddle board, paddle the board for 20 min, continue to add sodium bicarbonate in 3 times u...

Abstract

The invention provides a fur tanning method based on activated rubber seed oil. The method comprises the following steps: (1) adding water and sodium chloride into a paddle-tumbler; then, paddling a paddle of the paddle-tumbler; when sodium chloride is fully dissolved, adding a pickled fur blank; after within 5-10 minutes, adding an aldehyde tanning agent; after 10-30 minutes, adding sodium hydrogen carbonate to adjust the pH value of the mixed liquid in the paddle-tumbler to 5.0-5.5; intermittently paddling the paddle for 4-6 times subsequently; and then standing for 8-12 hours; (2) adding sodium hydrogen carbonate into the paddle-tumbler to adjust the pH value of the mixed liquid to 6.5-7.0; then, standing for 8-12 hours; and taking out the fur blank, and drying the fur blank till the water content is 30-40wt%; (3) uniformly smearing the activated rubber seed oil on the meat face of the fur blank, and then putting in a rotary drum, and intermittently rotating for 4-16 hours under the condition that the temperature is 25-55 DEG C and the air humidity is 70-90%; and 4) taking out the fur blank from the rotary drum, drying the fur blank till the water content is 20-30wt%, and then carrying out dry cleaning to remove the activated rubber seed oil which is not reacted with the fur blank.

Description

technical field [0001] The invention belongs to the field of fur processing and relates to a fur tanning method based on activated rubber seed oil. Background technique [0002] Fur is also known as fur and fur. Fur products are characterized by elegance, dignity, light weight and cold protection. Tanning is a process in which tanning agent molecules penetrate into the skin and combine with the active groups of raw hide collagen fibers, which is an important link in fur production. After tanning, the water resistance and heat resistance of the fur are improved, the resistance to microorganisms and chemicals is enhanced, the cohesion of the leather fibers is reduced, the shrinkage of the volume is reduced, the softness of the leather board is good, and the combination of the hair and the leather is firm. degree enhancement. [0003] The tanning methods of fur include chrome tanning, aldehyde-aluminum tanning, oil tanning and semi-oil tanning. The slab strength of chrome ta...
