Problems solved by technology

In the article "Flame Retardant Properties of Down Fiber Treated by Glutaraldehyde Grafting Dicyandiamide", the down fiber was modified by flame retardant grafting. Although the flame retardant aging of down fiber was improved to a certain extent, the grafted Dicyandiamide has a certain degree of toxicity, and it is harmful to directly contact with the skin, and its practical application value is low

Embodiment Construction

[0013] This embodiment adopts duck feather to process, and the process steps are:

[0014] (1) Pre-treatment: first wash the down with water, degrease, remove impurities, and then dry it, then mix and stir the down with the pre-treatment solution for 10 hours at a volume ratio of 1:4, take it out after the treatment, and wash it for 3 times before use. Described pretreatment liquid is formulated by the weight ratio of sodium lauryl sulfate: thiourea: deionized water=0.5:1:80;

[0015] (2) Cross-linking modification treatment: put the down obtained in step (1) into an aqueous glutaraldehyde solution with a concentration of 2%, react at 55°C for 1 hour, filter after the reaction, and put the filtrate into carboxylated β-ring In the dextrin nano-silver composite solution, stir and mix evenly, add absolute ethanol, filter after reacting for 30 minutes, and heat-treat the filtrate at 70°C for 1 hour before use;

[0016] (3) Post-treatment: Put the product of step (2) into the post...

Abstract

The invention discloses a treatment method of down feather with a long-acting electromagnetic radiation shielding effect. According to the treatment method disclosed by the invention, the treatment method is divided into three steps, pretreatment is firstly carried out on the down feather by utilizing pretreatment liquid, so that the surface performance of fiber is improved, and the reaction activity is increased; during a follow-up cross-linking modification treatment process, grafting treatment can be firstly carried out by utilizing glutaraldehyde, and then functionalized treatment is carried out on the fiber by using a carboxylic beta-cyclodextrin-nanosilver composite solution, and a beta-cyclodextrin-nanosilver composite material is grafted to the fiber; modified down feather fiber is further treated by post-treatment liquid, and finally, the down feather which has effects of resisting electromagnetic radiation, resisting bacteria and resisting water washing is obtained; compared with down feather after being treated through a traditional technology, the modification effect of the down feather disclosed by the invention is more durable, and the additional economic value of a down feather product is greatly increased.

Description

technical field [0001] The invention relates to the technical field of down fiber treatment, in particular to a treatment method for down with long-term electromagnetic radiation shielding effect. Background technique [0002] Down fiber is a kind of natural animal protein fiber. It is light, bulky, breathable and moisture-permeable, and has excellent warmth retention effect. It is often used in down clothing and products. In the production process, down raw materials need to undergo a series of treatments before they can be used as fillers. Down wool materials must go through procedures such as cleaning, degreasing, deodorization, disinfection, and drying. If the pre-treatment process is not handled properly, it will directly affect The use effect of down. [0003] Since down is an animal product, it has the disadvantages of being flammable, easy to be eaten by moths, easy to breed microorganisms, low added value of the product, and high maintenance and washing requirement...
