Filament spun-bonded antibacterial non-woven fabric framework material and a manufacturing method and application thereof

Abstract

The invention provides a filament spun-bonded antibacterial non-woven fabric framework material and a manufacturing method and application thereof. The antibacterial non-woven fabric framework material is composed of composite filaments with a skin-core structure, and the intrinsic viscosity of a skin layer material is 0.95-1.00 dl/g; the intrinsic viscosity of the core layer material is 0.61-0.68dl/g; based on the total mass of the composite filament, the skin layer accounts for 30-50 wt% of the total mass of the composite filament, and antibacterial master batches accounting for 1.2-4.0 wt%of the raw materials of the skin layer are added into the skin layer. The material has the advantages of high air permeability, high temperature resistance, broad-spectrum and efficient antibacterialproperty, safe and harmless contact, slow release but not dissolution of the antibacterial agent, good water resistance and discoloration resistance, the appearance of the material has the aestheticfeeling of the bi-component composite continuous filament, the production process and the finished product are green and environment-friendly, no peculiar smell is generated, no harmful substances such as VOC and the like are contained, and the material completely meets the requirement of environmental protection.

Description

technical field [0001] The present invention relates to a kind of non-woven fabric material, particularly relate to a kind of skeleton material of filament spun-bonded antibacterial non-woven fabric and its manufacture method and application. Background technique [0002] 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-conditioning systems, and household purifiers. These air purification / filtration systems all need to match the filter element processed by the filter material, so the filter material should rise with the tide and the market demand will last for a long time. With the deepening of air pollution control, the control of particulate pollu...

AI Technical Summary

Problems solved by technology

[0004] 1. The cloth surface of the framework material treated with antibacterial solution impregnated has potential safety hazards and poor discoloration resistance after being touched by the human body. During the impregnated mother liquid treatment, due to the obvious problem of color difference on the cloth surface, additional dyeing treatment is required, which increases the process and cost ;

[0005] 2. The antibacterial agent component coated on the surface of the framework material after dipping antibacterial solution is easy to dissolve, resulting in a short effective service life and poor water resistance. More importantly, this process cannot cope with increasingly stringent environmental monitoring

[0006] 3. The short-fiber antibacterial skeleton 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;

[0007] 4. The arrangement and orientation of the component fibers of the short fiber antibacterial skeleton material is chaotic, and the appearance color is darker after molding, and the aesthetic feeling of the fabric style is poor;

[0008] 5. The short-fiber antibacterial skeleton material is mostly added with low-melting-point ES fiber for hot-melt bonding, which causes it to be easily deformed at high temperature, which is not conducive to the subsequent lamination and discount processing
