Problems solved by technology

[0003] The applicant found that due to the lipid substances on the surface of feathers and down, and the distribution of disulfide bonds, the protein reactivity on the fiber surface is low, the hydrophilicity is poor, and the fiber reaction accessibility is poor, so it is difficult to perform functions through the traditional grafting process. tidy

Abstract

The invention discloses a feather and down surface finishing method and relates to feather and down surface treatment technology. Ionic liquid and lithium bromide-phytic acid complex solution are applied to surface finishing on down aggregates through a two-step combined process; the microstructure of finished down fiber is restructured, the hydrophilic performance is significantly improved, and further the number of reactive groups on the surface of leather and down can be significantly increased. The feather and down surface finishing method can be completed inside a washing machine insteadof a special unit processing machine, and chemical finishing is mild in condition and has the technical advantage of energy conservation.

Description

technical field [0001] The invention relates to the technical field of feather and down surface treatment, in particular to a feather and down surface modification method for developing new functional down materials. Background technique [0002] Feather and down fiber is the natural fiber material with the best thermal insulation performance, and it is an ideal filler for processing cold-proof textiles (clothing, bedding, etc.). Since feather down is a kind of fibrous protein, the content of keratin is as high as 80%. Keratin has a stable spatial network structure, tight crystallization area, and regular molecular chains, which is due to the large amount of -S-S in the peptide chain. - Bond cross-linking and intermolecular hydrogen bonds, ionic bonds and ester bonds and other chemical bonds. Even so, because feathers and down are protein components, bacteria are easy to breed under hot and humid conditions, mildew occurs, and the quality of down is significantly reduced. I...
