Abstract

The invention provides a method for preparing antibacterial deodorant high-filling-power down feathers. The method comprises the following steps: (1) performing color separation, screening and impurity removal on goose or duck feathers; (2) performing aerosol spray cleaning on the pretreated feathers, and drying in vacuum; (3) grinding the cleaned feathers by a grinder, adding composite alkali liquor at the temperature of 60-80 DEG C for treating for 2-4 hours, regulating the pH to be 7, filtering while hot to obtain grey feathers, washing with water and drying; (4) adding the grey feathers and a bleaching and dyeing liquid into a bleaching and dyeing cell for bleaching and dyeing, and soaking in a silver-loaded nano antibacterial agent aqueous solution. According to the method disclosed by the invention, the goose or duck feathers serve as a raw material for producing the down feathers, the raw material source is wide, the production cost is reduced, and the prepared down feathers are low in wing stem content and high in filling power and meet the high-quality requirement of consumers.

Description

technical field [0001] The invention belongs to the technical field of down preparation, and in particular relates to a method for preparing antibacterial and deodorizing high-loft down. Background technique [0002] Down is the fluff that grows on the abdomen of geese and ducks, and is called feathers in flakes. Since down is a kind of animal protein fiber, there are tens of thousands of small triangular pores densely covered on the down ball-shaped fiber, which can shrink and expand with the change of temperature, and has the function of temperature adjustment, which can absorb the flowing hot air from the human body and isolate the invasion of cold air from the outside. . From the analysis of the bulkiness test, down is one level higher than silk, cotton and other thermal insulation materials. For example, the minimum standard of 450 degrees fluffy 90 duck down is also more fluffy than silk and cotton, so down is purely used as a thermal insulation material. The economi...
