Abstract
The invention relates to a production method of a filtering material. The method adopts a four-layer structure, namely the first layer is a protective layer, the second layer is made of filtering cotton, the third layer is made of melting and spraying filtering materials with an antibiosis function and the fourth layer is of a protective layer structure with an antibiosis function. The four-layer structure is characterized in that: 1, the first layer is made of 35g/m<2> of gray antibiosis spunbond, 2, the second layer is made of 200 g/m<2> of activated carbon filtering cotton, 3, the third layer is made of 60 g/m<2> of antibiosis filtering cotton, the filter efficiency on NaCl particles with 0.3 microns achieves 97% under the condition of 85LPM; and 4, the fourth layer is made of 35 g/m<2> of white antibiosis spunbond.
Description
Technical field
A kind of invention relates to a kind of production method of protective filtering material.In order to satisfy the requirement of electric welding respiratory protection material, adopt the several functions material adapted, satisfied dustproof, anti-pernicious gas, antibacterial functions.Solve some materials of tradition single problem of filtering function under electric welder's environment for use.
Background technology
The protective materials of electric welding application requires dustproof, also will prevent pernicious gas.At present a lot of electric welders' protective mask does not have this two functions.
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 design 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 for spunbond, and spunbond grammes per square metre mainly can be 10-40g/m2.Main feature is to have antibacterial functions; The second layer is filter cotton, and the material that this filter cotton is comprised of electret fiber and activated carbon granule, this material have very high appearance dirt performance and to the adsorption capacity of pernicious gas; The 3rd layer is the melt-blown filter materials with antibacterial functions, and the filter efficiency of this material is higher, and a gradient filtration performance is provided, and this layer strainability is under the air quantity of 85LPM, and efficient is greater than 95%; The 4th layer for having the protective layer structure of antibacterial functions, can be spunbond, woven fabric or looped fabric etc.
The specific embodiment:
The present invention adopts four-layer structure: ground floor is protective layer; The second layer is filter cotton; The 3rd layer is tool
The melt-blown filter materials that antibacterial functions is arranged; The 4th layer for having the protective layer structure of antibacterial functions.
Ground floor is: the 35g/m2 grey is antibiotic spunbond; The second layer is that the 200g/m2 activated carbon filtration is cotton; The 3rd layer is that the antimicrobial filtering of 60g/m2 is cotton, and filter efficiency reaches 97% to the NaCl particle filtering efficient of 0.3 μ m under the 85LPM condition; The 4th layer is that 35g/m2 white is antibiotic spunbond.
