Multifunctional self-reinforced type double-component filament electrostatic filter material as well as preparation method and application thereof

Abstract

The invention provides a multifunctional self-reinforced type double-component filament electrostatic filter material as well as a preparation method and application thereof. The preparation method ofthe filter material comprises the following steps that 1) melt spinning is carried out, wherein a component A and a component B are adopted to form a skin-core structure continuous double-component composite filament after being subjected to melt spinning, the component A comprises a skin layer polymer and a functional medium with an electricity storage effect, and the component B comprises a core layer polymer and a functional medium with an antibacterial and mildew-proof effect; 2) a net is formed, and specifically the skin-core structure continuous two-component composite filament form thenet after being split; 3) reinforced forming is carried out, and specifically hot air is adopted for fusion, adhesion and curing; and 4) high voltage electrostatic treatment is carried out, and specifically the material is charged. According to the self-reinforced type double-component filter material, single-layer medium-efficiency and high-efficiency filter materials can achieve the same filtering efficiency as a composite filter material, meanwhile, the effects of being antibacterial, mildew-proof, high in stiffness and electrostatic adsorption are achieved, and the GB/T21551 antibacterialstandards are met.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a multifunctional self-reinforcing two-component filament electrostatic filter material and its preparation method and application. Background technique [0002] In the field of air filtration such as vehicle-mounted air conditioners and fresh air purification, the mainstream technologies and products in the domestic and foreign markets are mainly composite textile filter materials. The filter materials have reached the corresponding filtration efficiency. Most of them are composite materials related processes and products, especially in the field of medium and high-efficiency filtration, that is, F-grade and H-grade filter materials, which are mostly melt-blown fine filter materials. It is compounded with non-woven fabric skeleton reinforcement materials through glue compounding, ultrasonic bonding or high temperature and high pressure compounding, so as to meet different levels...

AI Technical Summary

Problems solved by technology

[0005] 1. The cloth surface of the skeleton material treated with the antibacterial liquid dipping has potential safety hazards and poor discoloration resistance after being touched by the human body. Due to the obvious problem of color difference on the cloth surface during the dipping mother liquor treatment, additional dyeing treatment is required, which increases the process and cost. , the antibacterial agent component coated on the surface of the framework material after dipping antibacterial liquid treatment is easy to dissolve, resulting in a short effective service life and poor water resistance, and more importantly, the process is not green

[0006] 2. The short-fiber antibacterial framework material has a small rebound deformation after being pleated in the rear channel, which is not conducive to the disassembly and assembly of the filter element. The component fibers of the short-fiber antibacterial framework material are arranged in disorder, and the appearance color is dark after molding. The fabric Poor style aesthetics;

[0007] 3. The short-fiber antibacterial skeleton material is mostly added with low-melting-point ES fiber for hot-melt bonding, which makes it easily deformed at high temperature, which is not conducive to the subsequent lamination and discount processing;

[0009] To sum up, there is no filter product in the industry that combines the advantages of antibacterial, mildew, electrostatic adsorption, self-reinforcement, high stiffness, and direct discounts.
