Abstract
The invention relates to a production method of a filtering material. The filtering material adopts a four-layer structure: a first layer is a protective layer; a second layer is filtering cotton; a third layer is a melt-blowing filtering material with an antibacterial function; and a fourth layer is a protective layer structure with the antibacterial function. The production method has the characteristics that 1, a material of the first layer: 35g/m<2> of grey antibacterial spunbond; 2, a material of the second layer: 200g/m<2> of active carbon filtering cotton; 3, a material of the third layer: 60g/m<2> of antibacterial filtering cotton, wherein the filtering efficiency on NaCl grains with the size of 0.3 micron reaches 97% under the condition of 85LPM; and 4, a material of the fourth layer: 35g/m<2> of white antibacterial spunbond.
Description
Technical field
A kind of invention relates to a kind of production method of protective filtering material.In order to meet the requirement of electric welding respiratory protection material, adopting several functions material adapted, meeting dust-proof, anti-pernicious gas, antibacterial functions.Solve some materials of tradition problem that filtering function is single under electric welder's environment for use.
Background technology
The protective materials of electric welding application requires dust-proof, also will anti-pernicious gas.The protective mask of a lot of electric welder does not have this two functions at present.
Summary of the invention
The main contents of patent of the present invention have following several respects:
One, the present invention adopts four layer material structures to devise a kind of filtering material, and this material is mainly used in electric welder's respiratory protection and filters use.
Two, this material primary structure is: ground floor is protective layer, can be spunbond, and spunbond grammes per square metre can be mainly 10-40g/m2.Main feature has antibacterial functions; The second layer is filter cotton, the material that this filter cotton is made up of electret fiber and activated carbon granule, and this material has very high appearance dirt performance and the adsorption capacity to pernicious gas; Third layer is the melt-blown filter materials with antibacterial functions, and the filter efficiency of this material is higher, provides a gradient filtration performance, and this layer of strainability is under the air quantity of 85LPM, and efficiency is greater than 95%; 4th layer for having the protective layer structure of antibacterial functions, can be spunbond, woven fabric or looped fabric etc.
detailed description of the invention:
The present invention adopts four-layer structure: ground floor is protective layer; The second layer is filter cotton; Third layer is the melt-blown filter materials with antibacterial functions; 4th layer for having the protective layer structure of antibacterial functions.
Ground floor is: 35g/m2 grey is antibacterial spunbond; The second layer is that 200g/m2 activated carbon filtration is cotton; Third layer is that the antimicrobial filtering of 60g/m2 is cotton, and filter efficiency, under 85LPM condition, reaches 97% to the NaCl particle filtration efficiency of 0.3 μm; 4th layer is that 35g/m2 white is antibacterial spunbond.
Claims (6)
