Method for dyeing down feather

Abstract

The invention discloses a method for dyeing down feather. The method for dyeing the down feather comprises the following steps: separating the raw material feather into waste feather, feather slices and down clusters by using a feather separator; removing dust of the separated feather slices and the down clusters, adding the feather slices and the down clusters subjected to dust removal into a scouring machine for souring, subsequently dyeing the soured down feather, simultaneously dyeing and adding a levelling agent, dye and a color curing agent, and enabling the down feather to have different colors through the dyeing process. Through the method for dyeing the down feather, the conventional view that the down feather only has white color and gray color is broken, so that the genuine down feather is obtained; the theoretical basis is provided for the market innovation of the down feather industry.

Description

technical field [0001] The invention belongs to the field of down processing technology, and in particular relates to a down dyeing method. Background technique [0002] Down is a green natural protein fiber and a valuable biomass resource. It has the characteristics of lightness, softness, good thermal performance, rich resources, and high cost performance. [0003] In recent years, people's demand for down garments and products has been increasing. Consumers are more inclined to pursue the fashion sense of down jackets on the basis of down quality requirements. The dull and cold winter colors are particularly suitable Importantly, after mixing and matching down, the gradient color can be directly reflected through the white fabric, which not only increases the fashion sense of the down jacket, but also allows consumers to understand the quality of the down filled in the down jacket more intuitively. In the true sense of "down jacket", the research on down dyeing process h...

[0003] In recent years, people's demand for down garments and products has been increasing. Consumers are more inclined to pursue the fashion sense of down jackets on the basis of down quality requirements. The dull and cold winter colors are particularly suitable Importantly, after mixing and matching down, the gradient color can be directly reflected through the white fabric, which not only increases the fashion sense of the down jacket, but also allows consumers to understand the quality of the down filled in the down jacket more intuitively. In the true sense of "down jacket", the research on down dyeing process has positive and practical significance for promoting the development of down products industry and meeting the market innovation requirements.
