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

[0011] This embodiment adopts duck feather to process, and the process steps are:

[0012] (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. The pretreatment liquid is formulated according to the weight ratio of aluminum zirconate coupling agent: ethanol: deionized water=5:20:60;

[0013] (2) Cross-linking modification treatment: Put the down obtained in step (1) into a 2% glutaraldehyde aqueous solution, react at 55°C for 1 hour, add graphene oxide after the reaction, stir and mix evenly Ultrasonic reaction at 60°C for 2 hours, filter after the reaction, and heat-treat the filtrate at 70°C for 1 hour before use;

[0014] (3) Post-treatment: Put the product of step (2) into the post-treatment solution, stir and soak for 1.5 hours, take it out, wash it with deionized...

Abstract

The invention discloses a treatment method of machine washable down. The treatment method comprises three steps, firstly, down is subjected to surface treatment with a pretreatment solution containingan aluminum zirconate coupling agent to improve the dispersity of down fiber and extend the reaction interface of protein fiber, a foundation is laid for a following crosslinking grafting reaction, glutaraldehyde is taken as bridging in the crosslinking modification treatment, graphene oxide is oxidized and grafted to the down fiber, the comprehensive performance of the down is effectively improved, then, reinforcing treatment is performed through an aftertreatment solution, the down fiber with good dispersity, low probability of agglomeration, good toughness and excellent ductility is obtained, and the phenomena of hardening, breakage and the like of a conventional down product in the machine washing process can be effectively relieved. Compared with the prior art, the production processis simple, the use convenience of the down product is improved, and the market value is huge.

Description

technical field [0001] The invention relates to the technical field of down fiber processing, in particular to a processing method for machine washable down. 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 of down prod...
