Embodiment 1

[0032] Embodiment 1: the regenerated down fiber made with 3.0 kilograms of chicken feather superfine powder

[0033] The chicken feathers are cleaned, washed, bleached, and crushed to make 3-5 mm particles, and then ultra-fine powders with an average particle size of less than 2 microns are made by ultra-fine powder processing equipment.

[0034] Add 3 kg of superfine chicken feather powder gradually to 0.5% caustic soda solution with a bath ratio of 1:5, and ultrasonically disperse at room temperature for 30 minutes to make an emulsion with good dispersion properties.

[0035] Add the prepared chicken feather ultrafine powder emulsion into the polymerization kettle, add 53 grams of sodium hypochlorite and 180 grams of sodium sulfite, adjust the pH value to 2.0±0.2, then add 6.4 kilograms of acrylonitrile and 0.6 kilograms of methacrylic acid while stirring Methyl ester, at a temperature of 50°C and a stirring speed of 190rpm, the polymerization reaction was terminated after 1...

Embodiment 2

[0037] Embodiment 2: the regenerated down fiber made with 4.0 kilograms of duck down and duck feather superfine powder

[0038] Duck down (hair) is cleaned, washed, bleached and crushed to make 3-5 mm particles, and then ultra-fine powder with an average particle size of less than 2 microns is made by ultra-fine powder processing equipment.

[0039] Add 4.0 kg of duck down (hair) superfine powder gradually into 0.5% caustic soda solution with a bath ratio of 1:5, and ultrasonically disperse at room temperature for 30 minutes to make an emulsion with good dispersibility.

[0040] Add the prepared duck down (hair) ultrafine powder emulsion into the polymerization kettle, add 20 grams of sodium chlorate and 300 grams of sodium bisulfite, adjust the pH value to 2.0 ± 0.2, then add 6.0 kilograms of acrylic acid while stirring Nitrile, at a temperature of 60°C and a stirring speed of 190rpm, the polymerization reaction was terminated after 1.5 hours, and then the monomer was evapora...

Abstract

The invention relates to a regenerated down filament fiber and a manufacturing method thereof. The ultra-fine powder made of poultry feathers in the fiber is evenly distributed in polyacrylonitrile, and is combined with polyacrylonitrile macromolecules by covalent bonds. The content of down components is 20-40%, and the polyacrylonitrile group Mineral content is 60-80%. The steps of the present invention to produce the regenerated down filament fiber are as follows: using poultry feathers as raw materials to prepare ultra-fine powder, and acrylonitrile in redox system through graft copolymerization to make polyacrylonitrile spinning stock solution, and then through traditional Wet or dry spinning process route is processed into regenerated down filament fiber. The regenerated down filament fiber of the invention has the excellent properties of natural down, such as warmth retention, water resistance, good wrinkle resistance, softness, smoothness, lightness and the like. The source of processing raw materials is wide and the price is low; the processing route of down powder is simple and pollution-free; the spinning process does not change the processing route of traditional polyacrylonitrile fiber, which is easy for industrial production.

Description

technical field [0001] The invention relates to a protein-modified chemical fiber made from poultry feathers and a production method thereof. Background technique [0002] The traditionally developed regenerated protein fiber is spun from the protein solution extracted from natural animal milk or plants (such as peanuts, corn, soybeans, etc.). The research history of regenerated protein fiber is earlier, around the end of the 19th century and At the beginning of the 20th century, research began abroad. For example, in 1894, formaldehyde was added to the gelatin solution for spinning to produce gelatin fibers; in 1904, Todten Haupt spun with casein extracted from milk to produce casein fibers; In 1935, Ferretti conducted further research on casein fiber, and the Italian SNIA company developed casein fiber; in 1938, the British ICI company manufactured peanut protein fiber with a trade name of Atdil, which had a water absorption rate of about 14% and a breaking strength of It...
