Abstract
The invention relates to a manufacturing process of beach sheep fur, which comprises the following steps: (1) selecting materials; (2) pretreatment; (3) degreasing; (4) pickling; (5) tanning; and (6) finishing. Because the beach sheep fur is treated by the oxidant under the acidic condition, scales on wool can be removed, the wool is treated by the anti-felting resin, the difference between the forward friction coefficient and the reverse friction coefficient of the wool scales becomes small, and the migration from the tip to the root of the wool is stopped, so that the anti-felting effect is obtained.

Technical Field
The invention relates to the technical field of leather processing, in particular to a manufacturing process of beach sheep fur.
Background
The tanning industry in China plays a role in underestimating the export foreign exchange, enriching the market of urban commodity and developing the economy of rural pasture areas. The Tan sheep skin is commonly called as 'Bai Bao' in Ningxia wubao, is well known as 'light, warm and beautiful', and the skin is plump Mao Sui and naturally stranded, has the bending degree as high as nine times, is deeply favored by domestic and foreign customers, and is an unique livestock production resource in Ningxia regions.
Wool of the beach sheep is similar to wool of other varieties, and scales are grown on the surface layer. The kurtosis of each scale points to the tip of the fiber. This is why beach wool rolls out the felt. Once the beach fur is rolled in the processing and wearing processes, the quality and the appearance of the product can be affected, and the warmth retention property of the fur garment can be reduced.

In order to achieve the above purpose, the invention adopts the following technical scheme:
a manufacturing process of beach sheep fur is characterized in that: the method comprises the following steps:
(1) Selecting materials: selecting a beach sheepskin with beach wool, wherein the length of the beach sheepskin is 55-70 mm;
(2) Pretreatment: soaking the Tan sheep skin in 3% sodium chloride solution for 120 min, taking out, washing with clear water, and finally drying the Tan sheep skin at 20-30 ℃;
(3) Degreasing: placing the Chan sheep skin into warm water at 40-45 ℃, adding a degreasing agent into the warm water, stirring for 5 minutes in a rotating way, soaking for 3 hours, taking out, and cleaning with clear water;
(4) Pickling: putting the Chan sheep skin into a blended pickling solution, adding an oxidant, stirring for 5 minutes in a rotating way, soaking for 5 hours, keeping the blended pH value at 5.7-6.5, taking out, cleaning with clear water, and drying at a low temperature of 25-35 ℃;
(5) Tanning: putting the Chan sheep skin into a blending tanning solution, stirring for 5 minutes in a rotating way, soaking for 3 hours, taking out, cleaning with clear water, and drying at a low temperature of 23-28 ℃;
(6) And (3) finishing: and (3) treating wool on the Tan sheep skin by using anti-sticking resin, and then performing natural drying and then finishing and warehousing.
Further, the wool length of the Tan sheep skin selected in the step (1) is 62 mm.
Further, in the step (2), the Channa Argus skin is dried at a low temperature of 25 ℃.
Further, the degreasing agent AP-degreasing agent in the step (3).
Further, a bacitracin agent is added in the step (4).
Further, the prepared pickling solution in the step (4) is prepared by taking hydrochloric acid, industrial salt and water=2:3:5 according to the weight.
Further, the pH is adjusted to be kept at 6.1 in the step (4).
Further, in the step (4), the Channa Argus skin is dried at a low temperature of 30 ℃.
Further, the blending tanning solution in the step (5) is prepared by taking chromium-aluminum composite tanning agent, sodium carbonate and water according to the weight parts, wherein the ratio of the sodium carbonate to the water is 1:11:700.
Further, in the step (5), the Channa Argus skin is dried at a low temperature of 26 ℃.
Compared with the prior art, the invention has the following beneficial effects:
according to the invention, the beach sheep fur is treated by the oxidant under the acidic condition, scales on wool can be removed, the wool is treated by the anti-felt resin, the difference between forward and reverse friction coefficients of the scales becomes small, and the migration from the tip to the root of the wool can be stopped, so that the anti-felt rolling effect is obtained.
