Down feather washing technology

Abstract

The invention discloses a down feather washing technology. The down feather washing technology comprises the following steps that first, dedusting is performed; second, feather is separated; third, pre-washing is performed, and some dust and impurities are removed, wherein every 0.5 KG to 1 KG of down feather is washed through 45 KG to 55 KG of clean water, and the cleaning time ranges from 4 min to 8 min; fourth, deep cleaning is performed, wherein pre-washed down feather is thrown into 25 KG to 35 KG of warm water with the temperature ranging from 30 DEG C to 40 DEG C, and special down feather detergent with the concentration being 1.5% to 3.5% and deodorant with the concentration being 0.2% to 0.4% are added; fifth, rinsing is performed, 25 KG to 35 KG of clean water is added for rinsing for 4 min to 5 min at each time, then sewage is drained, clean water is added for rinsing, and rinsing is performed for 10 times to 13 times; sixth, dewatering is performed, the rinsed down feather enters a centrifugal to be dewatered; seventh, half drying is performed; eighth, drying is performed; ninth, cooling is performed. The down feather washing technology has the advantages that adhering substances between down feather fibers are reduced, the fluffy degree of down feather is improved, the amount of static air in the down feather is increased, and the thermal insulating performance of the down feather is greatly improved.

Description

technical field [0001] The invention relates to a feather cleaning process. Background technique [0002] Down products are favored by consumers for their lightness, thinness and warmth. Down plays a decisive role in the thermal performance of down products. However, the raw poultry hair collected by mechanical or manual depilation and live plucking after slaughtering and scalding is mixed with a large number of hard flakes, long hair flakes, immature hairs, impurities and other sundries outside feathers and down, as well as a large number of bacteria. Microbes such as viruses cannot be directly used as fillings for down products, so they must be cleaned before they can be used. Therefore, the cleaning link is a key link in the down processing process. Factors such as the amount of down cleaning agent, cleaning time, and cleaning temperature all affect the thermal performance of the final down. Moreover, in order to save washing costs and washing losses, domestic counterpa...
