Production process of hot-molten non-woven fabric electrostatic fiber filter screen

Abstract

The invention relates to a production process of a hot-molten non-woven fabric electrostatic fiber filter screen, and belongs to the technical field of new material processing. The production process comprises the following steps of firstly, fiber unpacking and mixing, secondly, carding, thirdly, web forming, fourthly, compounding, fifthly, hot melting bonding, sixthly, cooling and seventhly, edge cutting, winding and packaging. According to the production process, the hot-molten non-woven fabric electrostatic fiber filter screen can be obtained without adopting an electret technology. Odorless electrostatic adsorbed polypropylene fibers are adopted as raw materials, a hot-molten non-woven fabric production process method is utilized, in the carding process, electrostatic rods with the polarity opposite to that of the odorless electrostatic adsorbed polypropylene short fibers are arranged in front of a carding machine, meanwhile, a humidifier is mounted below the carding machine, and it is guaranteed that relative humidity in the carding process is 60% or above; and under the combined action of the electrostatic rods and the humidifier, electrostatic fibers overcome the electrostatic fiber bonding phenomenon in the carding process, and the hot-molten non-woven fabric electrostatic fiber filter screen is manufactured.

Description

technical field [0001] The invention belongs to the technical field of new material processing, and in particular relates to a production process of a hot-melt nonwoven electrostatic fiber filter net. Background technique [0002] With the gradual improvement of people's living standards, people's requirements for the quality of life are getting higher and higher, and the awareness of environmental protection is gradually increasing. Air pollution has attracted people's attention because it directly affects people's physical and mental health and normal life. An effective way to improve air quality is to filter the air, and various air purification products and air filter materials It emerged as the times require, but the existing ordinary air filter materials can only remove particulate matter, but cannot remove harmful gases and biological aerosols (bacteria, viruses, mold, protozoans, etc.), etc., aiming at these weaknesses of ordinary air purification materials, this Th...

Air pollution has attracted people's attention because it directly affects people's physical and mental health and normal life. An effective way to improve air quality is to filter the air, and various air purification products and air filter materials It emerged as the times require, but the existing ordinary air filter materials can only remove particulate matter, but cannot remove harmful gases and biological aerosols (bacteria, viruses, mold, protozoans, etc.), etc., aiming at these weaknesses of ordinary air purification materials, this The invention proposes a new air filter with the functions of antibacterial and harmful gas removal. At the same time, the traditional hot-melt non-woven fabric production method cannot produce hot-melt non-woven fabric electrostatic fiber filter net. The traditional process method can only To produce ordinary hot-melt non-woven fabric filter, if you want to make the hot-melt non-woven fabric filter have electrostatic effect, you must use electret treatment method, not only the cost is high, but the electrostatic effect is far inferior to hot-melt non-woven fabric Electrostatic fiber filter mesh, in order to process hot-melt nonwoven electrostatic fiber filter mesh with long-lasting electrostatic field and electrostatic charge, so a new technical solution is urgently needed in the prior art to solve this problem
