Feather down washing technology for reducing dust, matched dehydration device and control method thereof

Abstract

The invention discloses a feather down washing technology for reducing dust. The technology comprises the steps that 1, a fixed quantity of feather down to be cleaned is weighed and placed into the matched dehydration device; 2, medicaments are added into the matched dehydration device, and the feather down is started to be cleaned; 3, dust is removed from the feather down; 4, the feather down is dehydrated; the medicaments added in the step 2 are a feather down detergent and a non-ionic anti-static agent; the upper portion of the feather down in the step 3 is covered with a layering dense grid in a pressed mode, water is injected so as to enable the water level to be higher than the feather down, and dust on the water surface is removed. On the basis of the novel matched dehydration device, the feather down washing technology formula and parameters and the procedures of dehydration, drying, feather sorting, wool extracting and pile splicing are optimized and adjusted, the equipment cost is low, use is convenient, and under the condition of combining the novel technology, dust inside feather down can be effectively removed.

Description

technical field [0001] The invention relates to the field of down cleaning, in particular to equipment and technology for cleaning and dehydrating down. Background technique [0002] Down dust is an important indicator reflecting the washing process and quality of down. In the GB / T 10288-2017 draft for comments, the down quality loss rate, i.e. dust, has been clearly listed as indicators such as oxygen consumption, residual fat rate, and bulkiness. equal status. For a long time, down dust has been considered as the source of allergies induced by down products and respiratory symptoms; under the action of respiration, down dust can easily enter the human respiratory system, causing allergens to interact with mast cells, basophils, etc. The combination of cells can induce allergic rhinitis and rhinitis; it can also cause bronchial and throat mucous membrane edema, induce bronchospasm and asthma; Palate itching, causing allergic dermatitis, systemic allergic skin diseases, et...

AI Technical Summary

Problems solved by technology

Drugs and fast-breeding methods make the feathers of "fast-growing ducks" stunted, the maturity rate is low, the fat content is significantly higher than that of ordinary meat ducks, and the strength of rachis, barbules, and down silk is weaker; after plucking, After washing, it is more likely to generate dust, which will make the dust problem more serious

At present, many domestic down production enterprises use adhesives to adhere dust to the surface of down fibers based on the "adhesion mechanism", thereby avoiding the occurrence of dust problems. The appearance of down produced by this method is poor, the luster is black, and the bulkiness of down is damaged. Seriously, the light-weight and warm-keeping properties of down are lost, and the use of adhesives will gradually release formaldehyde, small molecules of volatile organic compounds and other components during the drying process and wearing process of down, which will affect human health. At present, the idea of ​​using adhesives to reduce down dust It has been clearly boycotted by the European market, and the next step will be to punish such down product manufacturers

At the same time, through our research on Japanese down production enterprises, we found that some Japanese companies have sorted down dust through multiple methods of separating wool and raising feathers. This method uses special raising equipment, which requires a large investment in equipment and low work efficiency. Carry out technical research on down dust reduction technology
