Abstract

The invention relates to the technical field of gauze, in particular to a gauze for purifying air and a preparation method thereof; the preparation method comprises: (1) dispersing a foaming agent, a polymer emulsion and activated carbon fibers in an organic solvent The emulsion mixture is obtained, and electrospinning is carried out to obtain precursors; (2) soluble silver salts, polymer emulsions and organic solvents are mixed to form an impregnation solution, and the precursors are immersed in the impregnation solution to form fiber walls on the surface of the precursors; (3) Weaving to form a gauze structure, washing to neutral after pickling, and drying; (4) immersing the gauze structure in the immersion liquid in step (2) and lifting, baking, to obtain a gauze product; the yarn provided by the invention The preparation method of the net is simple and convenient, and the prepared gauze net has excellent purification effect, which can not only absorb suspended particles and toxic and harmful gases in the air, but also kill bacteria in the air and improve the ability of purifying the air.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a gauze for purifying air and a preparation method thereof. Background technique [0002] Window screen is a kind of mesh widely used on doors and windows, which can prevent mosquitoes and insects while not affecting indoor lighting and ventilation. Window screening can be divided into nylon window screening, metal window screening and glass fiber window screening according to its material. [0003] Nylon window screen is made of low-pressure and high-density polyethylene yarn through plain weaving. It has a variety of colors, such as the most common white, green and blue. This kind of material has light weight, beautiful appearance, acid resistance Alkali, anti-corrosion, ventilation and other advantages, it is often used in civil buildings, because of its high quality and low price, light material, easy to clean, so it is loved by consumers.
