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

[0014] This embodiment adopts duck feather to process, and the process steps are:

[0015] (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=1:1:80;

[0016] (2) Cross-linking modification treatment:

[0017] A: Put the down obtained in step (1) into the glutaraldehyde aqueous solution with a concentration of 2%, react at 55°C for 1 hour, and set aside after the reaction;

[0018] B: Dissolve chitosan completely in 1% acetic acid solution, mix the obtained solution with the materials in step A, and conduct ultrasonic reaction at 60°C for 2 hours, filter after the reaction, and heat-treat the filtrate at 70°C Standby after 1h;

[0019] (3) Post-treatm...

Abstract

The invention discloses a long-acting safety antibacterial down feather treatment method. The treatment method comprises three steps: micro-etching down feather by utilizing a pretreatment solution, adding a reaction active site of protein fibers, and grafting onto the protein fibers by utilizing glutaraldehyde in a cross-linked modification process, so that a foundation is set for introducing chitosan, the chitosan can be well combined with down feather fibers and is unlikely to drop, a safety antibacterial function of the down feather is achieved, the modified down is loose and smooth after being treated by a post-treatment solution, the hardening of the fibers is prevented, and the treatment is facilitated. Compared with the prior art, the production process is simple, the modification effect is durable, the heat preservation effect is not influenced, a product is healthy and environment-friendly, and the economic value of a down feather product is increased.

Description

technical field [0001] The invention relates to the technical field of down fiber treatment, in particular to a long-acting, safe and antibacterial down treatment method. 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 requirements. Widen the scope of use...
