The low-resistance and high-efficiency electrostatic cotton composite material comprises a melt-blown cotton layer and a melt-blown cloth layer, wherein the melt-blown cloth layer is compounded on the melt-blown cotton layer through a compounding machine under pressure. The melt-blown cotton layer is made of polypropylene superfine fiber and hollow polyester staple fiber mixed material, and the melt-blown cloth layer is water electret melt-blown cloth. The low-resistance and high-efficiency electrostatic cotton composite material is prepared by compounding water electret melt-blown cloth on a melt-blown cotton layer, has the characteristics of low resistance and high efficiency, and has the resistance of only 62Pa when the filtering effect reaches 99.7 percent. The filter has the characteristics of more stable filtration resistance, high dust holding capacity, long service life, difficult fluffing, more regular appearance and lower energy consumption.
Description
Technical Field
The utility model relates to a low-resistance and high-efficiency electrostatic cotton composite material which is suitable for being used as an adsorption material for fresh air systems, air purifiers, masks, protective masks and the like and can also be used for dust bags and the like.
Background
The adsorption material of new trend system, air purifier, gauze mask, protective mask at present adopts glass fiber, synthetic fiber, active carbon, non-woven fabrics etc. to make usually, these materials exist low efficiency when the low resistance, high resistance when high-efficient, or the low resistance holds the dust volume not enough shortcoming when high-efficient, need adopt multiple material to make the multilayer filter screen, reach required performance requirement with the form of multilayer filtration, filtering quality is ideal inadequately, and is bulky, and economic benefits is not high, needs often to wash the change.
Disclosure of Invention
The utility model aims to provide a low-resistance and high-efficiency electrostatic cotton composite material aiming at the defects, the electrostatic cotton composite material prepared by compounding the melt-blown cloth layer on the melt-blown cotton layer has the characteristics of low resistance, high filtering efficiency and high dust holding capacity, and the melt-blown cotton layer is combined with the melt-blown cloth, so that the electrostatic cotton composite material is thin in thickness, good in stability and attractive in appearance.
The low-resistance and high-efficiency electrostatic cotton composite material is realized by adopting the following technical scheme:
the low-resistance and high-efficiency electrostatic cotton composite material comprises a melt-blown cotton layer and a melt-blown cloth layer. And compounding the melt-blown cloth layer on the melt-blown cotton layer by a compounding machine under pressure.
The melt-blown fabric layer is a water electret melt-blown fabric layer, the density is 20-30 g/m, and the thickness is 0.2-0.32 mm.
The melt-blown cotton layer is made of polypropylene superfine fiber and hollow polyester staple fiber mixed material. The density is 50 ~ 110g/m, the thickness is 0.7 ~ 2.2 mm.
The melt-blown fabric layer adopts water electret polypropylene melt-blown fabric.
When the low-resistance and high-efficiency electrostatic cotton composite material is manufactured, the polypropylene superfine fibers and the hollow polyester staple fibers are made into melt-blown electrostatic cotton through a melt-blowing method, and a polypropylene melt-blown cloth layer is electret in a water electret mode, so that the filtering efficiency is improved, and the resistance is reduced. The melt-blown cloth layer is compounded on the melt-blown cotton layer through a compounding machine, and the fabric can be cut and used in a slicing mode.
The low-resistance high-efficiency electrostatic cotton composite material is prepared by compounding the melt-blown cotton layer and the melt-blown cloth layer, and has the characteristics of low resistance, high efficiency, more comfort, lower energy consumption, unique electret technology, more stable filtration resistance, high dust capacity, long service life, difficult fluffing and more regular appearance. The air purifier is suitable for environments requiring low resistance and high efficiency, such as fresh air systems, air purifiers, masks, protective mask filter elements and the like, and is also suitable for the fields of dust bags and the like.
