Embodiment Construction

[0015] An antibacterial and mildew-proof processing method for down, comprising the following steps:

[0016] (1) Degreasing, dedusting, cleaning, dehydrating, and drying the down raw materials to obtain pretreated down for use;

[0017] (2) Mix 0.1 parts by weight of tetraethyl orthosilicate, 0.01 parts by weight of cinnamaldehyde, 0.2 parts by weight of hydrochloric acid solution with a mass fraction of 0.05%, and 0.5 parts by weight of absolute ethanol, and stir at 40 for 0.5 hours to obtain a silica composite The sol is ready for use. Add 0.3 parts by weight of chitosan to 80 parts by weight of acetic acid solution, stir and dissolve evenly, then slowly add the silica composite sol dropwise and stir at 40°C for 0.5h, and obtain the down finishing solution after cooling;

[0018] (3) Immerse the pretreated down obtained in step (1) in the down finishing liquid obtained in step (2) for 10 minutes, then adopt a padding process with a liquid rolling rate of 150%, and finally d...

Abstract

The invention discloses an antibacterial and mildew-proof processing method for down feathers. The method comprises the following steps: firstly obtaining a silicon dioxide composite sol loading cinnamyl aldehyyde through a sol-gel method, mixing the silicon dioxide composite sol with acetum of chitosan to obtain down feather finishing liquid, padding the down feathers treated after degreasing, dedusting, cleaning, dehydrating and drying into the down feather finishing liquid, and conducting drying treatment. The down feathers obtained after the processing of the invention have excellent antibacterial and mildew-proof properties, are not prone to go bad and produce odor, have a lasting effect and good hygiene, and are beneficial to health of people.

Description

technical field [0001] The invention relates to the technical field of down processing, in particular to an antibacterial and anti-mildew processing method for down. Background technique [0002] Down is a kind of animal protein fiber that grows in the abdomen of geese and ducks in the shape of reed flowers. Down can absorb the flowing heat from the human body and isolate the invasion of cold air from the outside. It is a very popular thermal insulation material. Because the chemical composition of down is protein, and there are many bacteria in the raw material of down, in a hot and humid environment, down is prone to mildew, odor, and even deterioration, which not only threatens people's health, but also causes down to keep warm and fluffy. Performance drops. CN201110330230 discloses a method for finishing down with antibacterial function, which improves the antibacterial performance of down by finishing chitosan into down fibers. However, the effect of only using chito...
