Example Embodiment

[0030] Example one

[0031] First put the linen fabric in the working gas N 2 , The working pressure is 10Pa, and the discharge power is 100W in a low-temperature plasma device pretreated for 120s, then the fabric is pretreated with sodium hydroxide solution at 95-100℃ for 30min to remove impurities, and then the fabric is fully washed After removing the residual alkali, put the fabric in an oven for drying at a temperature of 80-90℃. After drying the fabric, take it out and weigh the quality of the linen fabric. Then the fabric was immersed in an acrylamide monomer solution with a concentration of 2mol / l for 2.5h, and then the fabric was dipped and rolled (rolling speed 1m / min, pressure 0.1Mpa), and then put into high-energy electron beam for irradiation After the reaction is completed, the fabric is taken out and washed with deionized water to remove the homopolymer and unreacted graft monomers on the surface of the fabric. Finally, it is dried in an oven to a constant weight....

Abstract

The invention discloses a method for performing durable flame-retardant grafting modification on fabric through cooperation of low-temperature plasma with electron beam irradiation. The method comprises steps as follows: firstly, the fabric is placed in a low-temperature plasma device for low-temperature plasma pretreatment; then the fabric is treated with a sodium hydroxide solution, and impurities such as colloid and the like in the fabric are removed; the fabric is taken out and fully washed with water, after residual sodium hydroxide is removed, the fabric is placed in an oven to be dried, and then the fabric is taken out and weighed; the dried fabric is soaked in a grafting monomer solution, then the fabric is taken out, the redundant liquid is rolled out by the aid of a padder, the fabric is wrapped with a plastic film and placed in a valve bag, and both the fabric and the valve bag are placed under a high-power electron beam for irradiation; after irradiation, the grafted fabric is washed with deionized water, and homopolymers and unreacted grafting monomers on the surface of the fabric are removed; then the washed fabric is placed in the oven to be dried for 24 h, and a product is obtained. The method has the advantages that the fabric has the lasting flame-retardant effect and the higher washing resistance.

Description

technical field [0001] The invention relates to a fabric grafting modification method, in particular to a durable flame-retardant grafting modification method for fabrics by low-temperature plasma and electron beam radiation. Background technique [0002] Low-temperature plasma technology is to use the plasma of inert gas or reactive gas to treat the surface of the material, and the surface macromolecules are activated and decomposed. The decomposed monomers may re-polymerize on the surface of the material, and may also generate gas and volatilize. The former can significantly roughen the material, while the latter has an etching effect on the surface of the material. Low-temperature plasma technology can be used in many fields such as sizing and desizing of fabrics, degumming of hemp fibers, calendering of fabrics, and hydrophilic treatment of synthetic fibers. Its own performance, so the application in the textile industry is of great significance. [0003] Electron bea...
