Problems solved by technology

[0002] With the growth of domestic fabric technology and people's needs, there are many fabrics with special functions on the market, such as waterproof, antibacterial, etc., but most antibacterial fabrics on the market only have the function of removing bacteria on the fabric and keeping the fabric clean. , and can not achieve multiple effects at the same time, the fabric of the present invention can also play a color-fixing effect and a better hand feeling due to the change of the existing components while being antibacterial, and with the change of the reaction structure, it can also improve the hydrophobicity of the fabric. Therefore, it is necessary to design an antibacterial and easy-to-decontaminate fabric with antibacterial and flame retardant properties

preparation example Construction

[0023] The invention provides a technical solution: an antibacterial and easy-to-decontaminate fabric and a preparation method thereof, comprising the following raw materials in parts by weight:

[0024] 50-80 parts of modified maleic anhydride copolymer, 70-100 parts of grafted cotton fiber.

[0025] Preferably, the modified maleic anhydride copolymer comprises styrene maleic anhydride copolymer and ethyl sulfate sulfone aniline.

[0026] Preferably, the styrene-maleic anhydride copolymer is prepared by dissolving styrene and maleic anhydride in toluene at a mass ratio of 1:2 to 1:4 for heating reaction, and then dissolving in tetrahydrofuran with 0.1 to 0.3 times the mass of maleic anhydride Finally, use 0.3 to 0.5 times the mass of maleic anhydride as methanol to precipitate, filter and dry, and repeat the operation several times to obtain it.

[0027] Preferably, the modified maleic anhydride copolymer is made of ethylsulfoneaniline, p-toluenesulfonic acid, styrene maleic...

Abstract

The invention discloses an antibacterial easy-to-clean fabric and a preparation method thereof, and relates to the field of fabrics. Styrene and maleic anhydride are subjected to precipitation polymerization to form a styrene-maleic anhydride copolymer, the styrene-maleic anhydride copolymer is subjected to acylation modification through ethyl sulfate sulfonylaniline, vinyl sulfone active groups are introduced to obtain a modified maleic anhydride copolymer, and the modified maleic anhydride copolymer reacts with grafted cotton fibers, so that the color depth and color fastness of the grafted cotton fiber and pigment can be improved, the latticed shape formed by the reaction can have double adsorption and complexation effects on silver ions and enhance the adsorption of the silver ions, and therefore, a better antibacterial property is achieved; and the existence of branched chains on the modified maleic anhydride copolymer can cause some effects to cause the increase of the glass transition temperature at a high temperature, the modified maleic anhydride copolymer is embedded in a latticed structure formed by crosslinking, the film pyrolysis temperature of the coated cotton fibers is higher than the carbonization temperature of the cotton fibers, and the cotton fibers can be carbonized firstly, so that the flame retardance of the cotton fibers is improved.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to an antibacterial and easy-to-decontaminate fabric and a preparation method thereof. Background technique [0002] With the growth of domestic fabric technology and people's needs, there are many fabrics with special functions on the market, such as waterproof, antibacterial, etc., but most antibacterial fabrics on the market only have the function of removing bacteria on the fabric and keeping the fabric clean. , can not achieve multiple effects at the same time, while the fabric of the present invention is antibacterial, it can also play a color-fixing effect and a better hand feeling due to the change of the existing components, and with the change of the reaction structure, it can also improve the hydrophobicity of the fabric. Therefore, it is necessary to design a kind of antibacterial and easy decontamination fabric with antibacterial and flame retardant properties. Conten...
