Abstract

The invention discloses a processing method for enhancing fluffiness of white duck down. The method includes the following steps: mixing ferric chloride hexahydrate, ferrous sulfate heptahydrate and water, heating and stirring, adding ammonia water, stirring uniformly, adding humic acid and whey protein, stirring continuously, adding mercaptoethanol, stirring continuously, removing mercaptoethanol, cooling, filtering, washing to neutrality, and drying the mixture to obtain prefabricated materials; washing white duck down, drying, adding the prefabricated materials, coconut oil hydroxyethyl sodium sulfonate, laurel essential oil, sodium dodecyl sulfate and water, uniformly mixing, dipping, filtering and washing the mixture to obtain pretreated white duck down; and drying the pretreated white duck down, spraying a down finishing agent in the drying process, and sterilizing to obtain the white duck down with high fluffiness.

Description

technical field [0001] The invention relates to the technical field of down processing, in particular to a processing method for enhancing the bulkiness of white duck down. Background technique [0002] Down products are favored by the market and consumers because of their unparalleled natural fiber advantages and unique fluffy and warm performance. During the processing of down products, the heavy metal impurities and dust carried by the down are difficult to eradicate during the rinsing process, which affects the comfort of the down products, and easily causes the breakage of the down fibers, resulting in poor bulkiness. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a processing method for enhancing the bulkiness of white duck down. The obtained white duck down with high bulkiness has a good waterproof effect, is not easy to be affected by moisture, is not easy to cause breakage of...
