A polyolefin spunbonded filament electrostatic skeleton filter material with antibacterial and antifungal functions and its preparation method and application

Abstract

The invention provides a polyolefin spunbonded filament electrostatic skeleton filter material with antibacterial and antifungal functions and its preparation method and application. After viscose melt spinning, a continuous two-component composite filament with a sheath-core structure is formed; component A includes polyethylene and a functional medium with electricity storage, and component B includes polypropylene and a functional medium with antibacterial and antifungal effects; or A component includes polyethylene and a functional medium with antibacterial and antifungal effects, and B component includes polypropylene and a functional medium with electricity storage; 2) Forming a web: continuous skin-core structure two-component composite filament through the sub-filament 3) Reinforcement forming: use hot air fusion bonding to form a two-component spunbond material; 4) High-voltage electrostatic treatment: charge the two-component spunbond material. The electrostatic filter material of the present invention has the effects of particulate matter filtration, electrostatic adsorption, broad-spectrum antibacterial and anti-mildew at the same time.

Description

technical field [0001] The invention relates to a nonwoven material, in particular to a polyolefin spun-bonded filament electrostatic skeleton filter material with antibacterial and antifungal functions, a preparation method and application thereof. Background technique [0002] At present, the concept of green environmental protection is advocated all over the world. Environmental governance has become a national policy and the will of the whole people. People are paying more and more attention to air pollution control. The people's vision of pursuing a better life must also be helped by clean air. Large-scale public buildings, car compartments, and family residences are the three main places for human activities, and the filtration and purification of the internal air is indispensable. In recent years, the air filter / air filter manufacturing industry has also been able to closely meet the needs of people's lives, and launched corresponding fresh air systems, vehicle air co...

AI Technical Summary

Problems solved by technology

[0004] 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

[0005] 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;

[0006] 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;

[0008] 5. At present, there is no filter material product with multi-functional advantages such as antibacterial, mildew proof, electrostatic adsorption, high stiffness and direct discount in the industry.
