Problems solved by technology

Trichloroisocyanuric acid is a very strong oxidizing agent and chlorinating agent. It not only has a strong chlorine gas irritating smell, but also the fluffy performance of the treated down is poor, and the performance of the down is greatly damaged. The down products are antibacterial after being washed twice. almost complete loss of function

Abstract

The invention discloses a preparation method for washable and antibacterial down feathers. The method comprises the following steps of washing, dewatering and drying raw feathers, and removing residual dust and sand to obtain pretreated down feathers; adding a detergent into the pretreated down feathers for fine washing, then rinsing the pretreated down feathers with clear water, performing dewatering, adding a humic acid compound and chitosan to be uniformly mixed, and performing dipping, filtering, washing, drying and cooling to obtain the washable and antibacterial down feathers. The humicacid compound is prepared by adopting the following process of mixing humic acid and a sodium hydroxide solution, performing heating and stirring, adding disproportionated rosin and carbon nanotubes,performing shaking, adding soybean protein, adjusting the pH value of a system to be 8.8-9.4, adding monoepoxy-terminated polysiloxane to be continuously stirred, then carrying out microwave processing, performing distilling to remove the water, and performing freeze drying to obtain the humic acid compound. The obtained washable and antibacterial down feathers are good in fiber fluffiness and excellent in antibacterial function; and after the washable and antibacterial down feathers are washed with the water for multiple times, the antibacterial performance is not reduced, the original elasticity and compression performance can be restored, and the fluffiness of the down feathers is guaranteed.

Description

technical field [0001] The invention relates to the technical field of down, in particular to a method for preparing water-resistant and antibacterial down. Background technique [0002] Feather and down materials contain a large number of pathogenic microorganisms. If the down and down products are not properly sterilized, a large number of pathogens will be carried in the down products, which will endanger people's health. The existing production process of antibacterial down includes the following processes: pre-separation process, ash removal process, fine separation process, washing process, dehydration process, finishing process, drying process, cooling process, and packaging process. [0003] The traditional antibacterial finishing of down generally uses trichloroisocyanuric acid to treat the down during the drying process. Trichloroisocyanuric acid is a very strong oxidizing agent and chlorinating agent. It not only has a strong chlorine gas irritating smell, but al...
