Problems solved by technology

In actual operation, velvet washing needs to be rinsed at least 10-14 times, otherwise the product will fail to pass the test due to insufficient amount of detergent and deodorant, and the effect of removing the odor of feather flakes and down is not ideal. When the cleanliness of raw materials is poor It is especially obvious, and the initial washing step has low efficiency, high water consumption, long drying process, high energy consumption, and low dehydration process efficiency. In order to achieve 90% cashmere content, the washed cashmere needs to be subjected to secondary fine separation. Low efficiency and damage to down

Embodiment 1350

[0042] Embodiment 1 350kg better quality goose down washing comparison test

[0043] Select 350kg of goose down from the 5th box wool with better quality in the same batch, and divide it into two groups for testing. The first group takes 200kg and operates according to the original washing process, and the second group takes 150kg according to the optimized washing process provided by the present invention. operate.

[0044] The process used for the first group of goose down washing is: after feeding 200Kg, add 6 tons of normal temperature water for initial washing for about 10 minutes, then release the water, add 6 tons of 45°C-50°C hot water, add 3kg of detergent, wash for 25 minutes, release the water, and rinse 10 times , adding 6 tons of normal temperature water each time, rinsing for 4 minutes each time, adding 0.6kg deodorant for the last rinsing, stirring for 5 minutes to release the fluff pulp, then dehydrating, dehydrating twice, and dehydrating takes 30 minutes in t...

Embodiment 2

[0051] Embodiment 2 500kg of better quality goose feather flakes washing comparison test

[0052] Choose 500kg in the better goose feather chip raw material (the 2nd-4 box wool) of same batch quality, divide into two groups and carry out the test, the first group gets 200kg and operates according to the original washing process, and the second group gets 300kg and provides according to the present invention The optimized washing process operation.

[0053] The washing process of the first group of goose feather flakes is the same as the washing process of the first group of goose down in Example 1, except that it is rinsed 8 times, which will not be repeated here.

[0054] The technology of the second group of goose feather flakes washing is: feed intake 300kg, add 3 tons of hot water of 58 ℃ and clean 660s (being 11min), detergent adds 3kg (1% of pinna weight), deodorant adds 1.2kg (pinna weight) 0.4% of the weight), rinse 8 times, add 6 tons of normal temperature water to e...

Embodiment 3

[0060] Embodiment 3 350kg duck down washing comparison test with poor quality

[0061] Choose 350kg in the duck down raw material (the 5th box wool) with poor quality of the same batch, divide into two groups and carry out the test, the first group gets 200kg and operates according to the original washing process, and the second group gets 150kg after the optimization provided by the present invention washing process operation.

[0062] The washing process of the first group of duck down is the same as the washing process of the first group of goose down in Example 1, except for 12 times of rinsing, which will not be repeated here.

[0063] The process of the second group of duck down washing is: feed 150kg, add 4 tons of hot water at 60°C for 800s (i.e. 13.3min), add 3kg of detergent (2% of the weight of the down), and add 1.2kg of deodorant (2% of the weight of the down) 0.8%), rinse 10 times, add 6 tons of normal temperature water for each of the first 9 rinses, rinse for ...

Abstract

The invention discloses a down feather washing technology. The down feather washing technology includes the following steps: (1) rough separation; (2) refined separation; (3) washing; (4) dewatering;(5) drying; (6) cooling; (7) secondary refined separation; and (8) inspection. Original feathers are divided into feather hair and feather pieces, and the down content of the feather hair reaches above 75%. The washing process includes cleaning and rinsing; during cleaning, a semi-box of hot water is used; during rinsing, a full box of water at a normal temperature is used; when the feather hair and the feather pieces are rinsed for the last time, a semi-box of water is added; when the feather hair is rinsed for the last time, a deodorant is added; dewatering, drying, and cooling is performedon the washed feather hair and the washed feather pieces, the cooled feather hair is packaged, and secondary refined separation is performed on the cooled feather pieces; the feather hair and the feather pieces are packaged respectively; and the packaged feather hair is inspected. The washing technology can reduce the frequency of rough cleaning and rinsing, can improve the efficiency, can reduceenergy consumption, and can save water, electricity, and the cost; and the feather hair can meet the national standard demand.

Description

technical field [0001] The invention relates to the field of down washing, in particular to an optimized energy-saving and water-saving down washing process. Background technique [0002] Down is one of the important raw materials for the production of clothing, bedding, etc., and is deeply loved by people because of its good appearance and thermal insulation performance. The newly purchased down is generally without any treatment. There are impurities, dust and bacteria on the down, and there will be a strong fishy smell. It needs to be treated many times before it can be used as processed clothing, bedding, etc. raw material. Washing is the most important treatment process for down, which is used to remove dust, bacteria, viruses, and odors. The process from washing down to drying is a fully automatic production line, which accounts for 70% of energy consumption and 100% of water consumption, and is also the bottleneck of down processing. . [0003] In the existing down...
