Problems solved by technology

[0007] 1 Too much emphasis on the "softening" process in dry finishing, ignoring the importance of strengthening softening;
[0008] 2 The variety of enzyme preparations used is single and cannot achieve the ideal softening effect
[0009] 3. The process design is conservative, and the arrangement is not designed according to the characteristics of the enzyme, resulting in low softening efficiency of the enzyme preparation
[0010] 4 There is no systematic and comprehensive research on the production technology of thin, light and soft sheep fur, and there is no step-by-step processing of sheep fur with biological enzymes
At the same time, there are no professional and non-professional literature reports

Embodiment 1

[0085] (1) Enzyme softening:

[0086] Add 0.1 part of sodium carbonate, 0.4 part of industrial pancreatin, 1.0 part of degreasing agent and 100 parts of fur into the groove. Adjust liquid ratio to 14 and temperature to 30°C. Swipe for 10 minutes and stop for 15 minutes. Afterwards, stroke for 3 minutes and stop for 20 minutes, and repeat this operation twice, and alternate forward and reverse strokes. Check the softening condition, gently push the back shoulder with the thumb, if the plush falls off, the softening meets the requirements. Out of the drum to carry out the operation of the next process.

[0087] (2) Washing:

[0088] 100 parts of furs are put into the scoring groove, and the adjustment liquid ratio is 15, and the temperature is 18°C. Swipe for 3 minutes on the front and back, and the drum comes out.

[0089] (3) pickling softening:

[0090] First add 70 parts of industrial salt and 50 parts of Yuanming powder into the groove. Adjust the liquid ratio to 18...

Embodiment 2

[0125] (1) Enzyme softening:

[0126] Add 0.3 parts of sodium carbonate, 0.8 parts of industrial pancreatin, 2.0 parts of degreasing agent and 100 parts of fur into the groove. Adjust the liquid ratio to 17 and the temperature to 32°C. Swipe for 15 minutes and stop for 25 minutes. After that, stroke for 5 minutes and stop for 25 minutes, and repeat this operation 4 times, and alternately stroke forward and reverse. Check the softening condition, gently push the back shoulder with the thumb, if the plush falls off, the softening meets the requirements. Out of the drum to carry out the operation of the next process.

[0127] (2) Washing:

[0128] 100 parts of furs are put into the scoring groove, and the liquid ratio of adjustment is 20, and the temperature is 21°C. Swipe for 5 minutes on the front and back, and the drum comes out.

[0129] (3) pickling softening:

[0130]First add 80 parts of industrial salt and 60 parts of Yuanmingfen into the groove. Adjust the liquid...

Embodiment 3

[0165] (1) Enzyme softening:

[0166] Add 0.6 parts of sodium carbonate, 1.2 parts of industrial pancreatin, 3.0 parts of degreasing agent and 100 parts of fur into the groove. Adjust liquid ratio to 20 and temperature to 34°C. Swipe for 20 minutes and stop for 30 minutes. Afterwards, stroke for 10 minutes and stop for 30 minutes, repeat this operation 6 times, and alternate forward and reverse strokes. Check the softening condition, gently push the back shoulder with the thumb, if the plush falls off, the softening meets the requirements. Out of the drum to carry out the operation of the next process.

[0167] (2) Washing:

[0168] 100 parts of furs are put into the scoring groove, and the adjustment liquid ratio is 25, and the temperature is 24°C. Swipe for 10 minutes each on the front and back, and the drum comes out.

[0169] (3) pickling softening:

[0170] First add 100 parts of industrial salt and 70 parts of Yuanming powder into the groove. Adjust the liquid ra...

Abstract

The invention discloses a method for performing multiple-step treatment on sheepskin by using biological enzymes, which is characterized in that industrial pancreatic enzymes, composite enzymes TA for acid pickling and softening and composite enzymes TB for acid pickling and softening are respectively used for performing softening treatment on sheepskin in an enzyme softening procedure and an acid pickling procedure; and the treated sheepskin is processed through the conventional process, thereby obtaining the very soft and lightweight sheepskin. Thus, the quality and added values of the sheepskin and products thereof are greatly improved.

Description

technical field [0001] The invention relates to a method for step-by-step processing of sheep fur into fur by using biological enzymes, which belongs to the field of fur processing. Background technique [0002] Fur is also called fur or fur. Fur products have always been synonymous with fashion and elegance, known as "soft gold". Fur clothing used to be synonymous with wildness and toughness. With the changes of the times and the continuous improvement of people's living standards, fur products began to develop in the direction of "comfortable, soft, novel and elegant". Light, soft" fur products. "Thin" means to meet the requirements of thinness and fullness under the premise of ensuring that various fur products have certain physical and mechanical strength. "Light" means that fur products feel close to the body, relaxed, elegant, and have no sense of weight when worn, that is, the so-called "light and quality, light but not buoyant", and "soft" means that the fur feels...
