Embodiment Construction

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0018] A kind of preparation method of composite long-acting antibacterial and anti-mite down fiber provided by the invention comprises the following steps:

[0019] (1) select down raw material;

[0020] (2) Pre-treatment: destemming of raw materials→removing dust and sand→fine separation→primary washing→washing→dehydration;

[0021] (3) Immerse the washed down raw materials into 0.6% (o.w.f) Sanitized antibacterial and anti-mite additive SanitizedAM98-12N, 1% (o.w.f) modified chitosan, 2% (o.w.f) Archroma chemical adhesive Immerse in 40-50℃ aqueous solution of AppretanN96101 for 30min;

[0022] (4) Dehydration process: the centrifuge first pre-centrifuges and dehydrates at a low speed of 300 rpm for 1.5 minutes, then spins and dehydrates at a high speed of 600 rpm for 6-8 minut...

Abstract

The invention discloses a preparation method of composite long-acting antibacterial and anti-mite down fibers. The preparation method comprises the following steps of: (1) selecting down raw materials; (2) pre-treating, namely removing stems of the raw materials, removing sand dust, finely classifying, carrying out primary washing, washing and dehydrating; (3) immersing the down raw materials, which are cleanly washed, into a water solution containing 0.6% (o.w.f) of a Sanitized antibacterial and anti-mite auxiliary agent AM98-12N, 1% (o.w.f) of modified chitosan, 2% (o.w.f) of an Archroma chemical binding agent Appretan N 96101 at 40-50 DEG C for 30min; and (4) dehydrating, pre-drying, baking and cooling the immersed downs. The down fibers prepared by the method provided by the invention has an obvious antibacterial and anti-mite effect; the bacteria inhibition rates on candida albicans, escherichia coli and staphylococcus aureus reach more than 99%, and the repelling ratio of house dust mites reaches more than 95%; the composite long-acting antibacterial and anti-mite down fibers have the long-acting property and have a protection effect on daily health of people, and the living quality of people is greatly improved.

Description

technical field [0001] The invention relates to a method for preparing fibers, in particular to a method for preparing composite long-acting antibacterial and anti-mite down fibers. Background technique [0002] Down products are made of down as a filling material. So far, there is no thermal insulation material in the world that exceeds the thermal performance of down. Down products are not only soft and warm, but also have a good touch and no pressure, which can normalize blood pressure and stabilize the central nervous system, so it also has an excellent effect on beauty. With the further improvement of people's living standards, down products have gradually entered the homes of ordinary people and become the most comfortable bedding products that everyone can enjoy. [0003] However, the chemical composition of down is a kind of protein, accompanied by animal fat. During the treatment process, after repeated degreasing and cleaning, impurities and bacteria cannot be com...
