Treatment method for down feather with electromagnetic radiation shielding and anti-static functions

Abstract

The invention discloses a treatment method for a down feather with electromagnetic radiation shielding and anti-static functions and relates to the technical field of down feather treatment. The treatment method for the down feather comprises the following steps of S1, pretreatment; S2, preparation of an electromagnetic radiation prevention solution; S3, modification; S4, soaking; S5, cooling. According to the method, the electromagnetic radiation prevention solution is used for modifying the down feather, so that the down feather has the function of electromagnetic radiation shielding; by adding plant juice, the electromagnetic radiation prevention performance of the down feather is further improved; an anti-static solution is used for soaking the down feather, after treatment is completed, the down feather has the electromagnetic radiation prevention performance, and the anti-static capacity of the down feather is high; through multi-time cleaning, the electromagnetic radiation prevention performance and anti-static capacity of the down feather cannot be lowered, and the problems are solved that after the down feather treated in the prior art is cleaned multiple times, the performance of the down feather is lowered, and the application quality of the down feather is influenced. The method is simple in process, low in cost and high in function, and the produced down feather ishigh in performance.

Description

technical field [0001] The invention relates to the technical field of down treatment, in particular to a treatment method for down with electromagnetic radiation shielding and antistatic functions. Background technique [0002] Down fiber is a kind of natural animal protein fiber. It is light, bulky, breathable and moisture-permeable, and has excellent thermal insulation 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] A Chinese patent discloses a treatment method for down with long-term shielding effect of electromagnetic radiation (authorized announcement CN105803806A). This patented technology first uses the pretreatment liquid to pretreat the down to improve the surface properties of the fiber and increase the reactivity. In the process of cross-linking modification, glutaraldehyde is used for grafting treatment first, and then the carboxylated β-cyclodextrin-nano-silver composite solution is used for functional treatment, and the β-cyclodextrin-nano-silver composite material is grafted On the fiber, the modified down fiber is further treated with a post-treatment solution, and finally the down with anti-electromagnetic radiation, antibacterial and washable properties is obtained. The additional economic value of down products can be improved, but the patent combined with the existing down treatment process, the existing treatment process is too cumbersome, and it does not have anti-static performance, after long-term cleaning, the anti-static ability and anti-shielding electromagnetic The radiation ability is reduced. At the same time, the patent is not perfect for the treatment of the modified down, and the treatment process is relatively cumbersome, and the anti-shielding electromagnetic radiation performance needs to be improved.
