Embodiment Construction

[0021] A kind of preparation technology of flame-retardant down textile material, comprises the following steps:

[0022] (1) Mix diethyl phosphite and N-methylol acrylamide at a mass ratio of 1.2:1 and heat up to 50°C. After the N-methylol acrylamide is completely dissolved, add 4% methanol of the mixture Sodium, react at 50°C for 5 hours, then let it stand for precipitation, and filter out the condensed N-methylolacrylamide and sodium methoxide to obtain a flame retardant precursor solution for later use;

[0023] (2) Raise the temperature of the flame retardant precursor solution to 70°C, then add epichlorohydrin which is 4 times the mass of the flame retardant precursor solution, and keep it warm for 8 hours to obtain a flame retardant for use;

[0024] (3) Using the semi-continuous core-shell emulsion polymerization method, add the pre-emulsified core layer and the shell layer monomer successively according to the core-shell mass ratio of 3:2, control the polymerization t...

Abstract

The invention discloses a preparation process of a flame-retardant down textile material. According to the preparation process, a flame retardant is compounded with an adhesive, and is then combined with down textile fabric by means of electrostatic flocking, wherein the flame retardant is prepared by using diethyl phosphite and the like; the obtained intumescent flame retardant is halogen-free and low-smoke, and meets the environmental protection requirements; furthermore, compared with the conventional flame retardant, the intumescent flame retardant has stronger chlorine resistance, and canstill maintain higher flame retardant performance after being washed with disinfectant fluid for a plurality of times; during preparation of the adhesive, the process and raw materials are optimized,so that the energy consumption is reduced, the use of formaldehyde is avoided, and the flocking fastness can be achieved very well; the final product not only has good hand feeling of the general down textile materials, but also is higher in down stiffness, so that the service cycle is prolonged, and an ideal flame retardant effect is achieved under the premise of environmental protection; the preparation process overcomes the flammability defect of the general down textile products, and has an ideal application prospect in the fields such as clothing and decoration.

Description

technical field [0001] The invention relates to the technical field of down production, in particular to a preparation process of a flame-retardant down textile material. Background technique [0002] Down is the fluff that grows on the abdomen of geese and ducks in the shape of reed flowers. Since down is a kind of animal protein fiber, there are tens of thousands of small triangular pores densely covered on the down ball-shaped fiber, which can shrink and expand with the change of temperature, and has the function of temperature adjustment, which can absorb the flowing hot air from the human body and isolate the invasion of cold air from the outside. . With the improvement of people's living standards, down and its products have entered thousands of households and are closely related to our lives. [0003] However, duck and goose down, which are natural protein fibers, are flammable. When a fire breaks out, they are easy to burn. They may burn the user at least, or threa...
