Filter layer and PTFE film under synthetic fibre fibre web antimicrobial filtering layer, acrylic fibers fibre web, composite fibre base fabric are fine by antistatic cotton and polypropylene
Dimension is combined, and the upper surface of composite fibre base fabric is equipped with acrylic fibers fibre web antimicrobial filtering layer, and the lower surface of composite fibre base fabric is set
There is filter layer under acrylic fibers fibre web;The upper surface of the acrylic fibers fibre web antimicrobial filtering layer is covered with PTFE film.
According to the above-mentioned filter cotton for high-speed EMUs PM2.5 air cleaning, the antistatic cotton is anti-to be adsorbed with
The cotton fiber of electrostatic agent.
Filter cotton according to claim 1 for high-speed EMUs PM2.5 air cleaning, it is characterised in that described
Filter layer is fibre web made of being reinforced by way of spun lacing as the acrylic fiber Jing Guo graft modification under acrylic fibers fibre web.
According to the above-mentioned filter cotton for high-speed EMUs PM2.5 air cleaning, the acrylic fibers fibre web antimicrobial filtering layer
Using acrylic fiber as raw material, by pretreatment so that polyamines is reacted with the cyano on acrylic fiber, in grafting polyamino and its
He reacts the azacyclo- of generation.
According to the above-mentioned filter cotton for high-speed EMUs PM2.5 air cleaning, the fiber of the polypropylene fibre is straight
Diameter is 5-40nm.
According to the preparation method of the above-mentioned filter cotton for high-speed EMUs PM2.5 air cleaning, it includes following step
It is rapid:
(1), the preparation of composite fibre base fabric: first preparing antistatic cotton, then logical using antistatic cotton and polypropylene fibre fiber
The base fabric that the mode of spun lacing is woven into fibre web as composite filtering material is crossed,
(2), acrylic fibers fibre web antimicrobial filtering layer then is bonded in the upper surface of above-mentioned composite fibre base fabric, then in composite fibre base
Filter layer under the lower surface bonding acrylic fibers fibre web of cloth;Finally PTFE film is covered in the upper surface of acrylic fibers fibre web antimicrobial filtering layer;
(3), naturally dry cuts and product is made.
Compared with prior art, the present invention obtain the utility model has the advantages that
1, the composite fibre base fabric compression strength in material of the present invention is high, good corrosion resistance, and filtration resistance is small;Acrylic fibers in material
Fibre web antimicrobial filtering layer is, by special pre-treatment, the cyano on polyamines and acrylic fiber to occur using acrylic fiber as raw material
It reacts, polyamino reacts the functional groups such as the azacyclo- generated with other in grafting, these functional groups are to common Gram-positive
Bacterium, negative bacterium, fungi, anaerobic bacteria, pneumobacillus, staphylococcus aureus, Candida albicans etc. have stronger inhibitory or killing effect,
Modified acrylic fiber is fabricated to antimicrobial filtering layer, is entirely free of metal ion, safe to the human body harmless, antibacterial effect is held
Long, broad-spectrum high efficacy, it is environmentally protective and washable;PTFE film in the material can effectively filter dust.
2, material of the present invention can filter blocking haze, effective stealthy killer -- bacterial virus, automobile crossed in air filtering
Tail gas, secondhand smoke, formaldehyde, dust mite, haze, Volatile chemical, air pollution poison gas, barrier droplet, Fluids and secretions make
It is influenced with, the pellet as brought by vehicle exhaust, absorbs and filters pollution poison gas etc., be widely used in medical treatment and defend
Raw industry, public arena;The mask either filter efficiency, gas permeability, antibiotic property, safety etc. for changing material production are all big
Surmount common mask greatly.
