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

[0012] This embodiment adopts duck feather to process, and the process steps are:

[0013] (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;

[0014] (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;

[0015] (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 feathers. The treatment method comprises the three steps of: 1) performing surface treatment to the down feathers with a pre-treatment solution containing an aluminum zirconium coupling agent to improve dispersibility of down feather fibers and expand a reaction interface of protein fibers, thereby laying a fundament for a subsequent crosslinking grafting reaction; 2) during crosslinking modification, with glutaraldehyde as a bridge, graft-adsorbing graphene oxide onto the down feather fibers, so that comprehensive performance of the down feather is effectively improved; and 3) performing reinforcement treatment with an after-treatment solution to obtain the down feather fibers being good in dispersibility, being not liable to agglomerate and having excellent toughness and malleability. The method effectively improves the problems of caking, fracture and the like during a machine washing process on conventional down feather products. Compared with the prior art, the treatment method is simple, can improve use convenience of the down feather products and has a huge market value.

Description

technical field [0001] The invention relates to the technical field of down fiber treatment, in particular to a treatment 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 produc...
