Generally, a filter is a filtration device that filters foreign substances in a fluid, and is classified into a liquid filter and an air filter. Among these, air filters are used in semiconductor manufacturing, computer equipment assembly, hospitals, etc. to remove biologically harmful substances such as microparticles such as dust in the air, bioparticles such as bacteria and molds, and bacteria to prevent defects of high-tech products with the development of high-tech industries. It is used in food processing factories, agriculture, forestry and fisheries, and is widely used in dusty workplaces and thermal power plants.

It is a kind of rotary internal combustion engine which obtains a rotational force by spraying on the vane of a turbine after obtaining. Since the gas turbine is composed of very precise parts, periodic maintenance is performed, and at this time, an air filter is used for pretreatment to purify the air in the compressor.

However, large particles of foreign matter accumulate on the surface of the filter medium and form a filter cake on the surface of the filter medium, and fine particles accumulate in the filter medium to block pores of the filter medium. As a result, when the particles accumulate on the surface of the filter medium, there is a problem of increasing the pressure loss of the filter and reducing the life.

When nanofibers are applied to a filter, the specific surface area is larger than that of a conventional filter medium having a large diameter, and flexibility of surface functional groups is also good.

Frequently used monomers include butadiene styrene vinylidene chloride or other vinyl compounds. Acrylic fibers contain at least 85% acrylonitrile and modacryl contains 35-85% acrylonitrile. When other monomers are included, the fiber has the property of increasing affinity for the dye. More specifically, in the production of acrylonitrile-based copolymers and spinning solutions, in the case of using acrylonitrile-based copolymers, nozzle contamination is less during the manufacturing of microfibers by the electrospinning method, and the electrospinning properties are excellent. By increasing the solubility in the solvent, it is possible to give better mechanical properties. In addition, polyacrylonitrile has a softening point of 300 ยฐ C. or higher and excellent heat resistance.

The weight percent of acrylonitrile monomer during polymer polymerization is too low for electrospinning when the weight percentage of hydrophilic monomer and the weight percentage of hydrophobic monomer are less than 60 due to the ratio of 3: 4. Even if the crosslinking agent is added to the nozzle, it is difficult not only to cause nozzle contamination but also to form a stable jet during electrospinning. In addition, in the case of 99 or more, the spinning viscosity is too high, and spinning is difficult, and even if an additive is added to reduce the viscosity, the diameter of the ultrafine fibers becomes thick and the productivity of the electrospinning is too low to achieve the object of the present invention.

Nylon 46 is made by polycondensation of tetramethylenediamine with adipic acid. Diaminobutane (DAB), a raw material, is prepared from the reaction between acrylonitrile and hydrogen cyanide.In the polymerization operation, a salt is prepared from diaminobutane and adipic acid in the first step, and then subjected to polymerization under an appropriate pressure. After conversion to a prepolymer, the solid of the prepolymer is prepared by polymerizing in a solid phase by treatment at about 250 ยฐ C. in the presence of nitrogen and water vapor.

Since polyethersulfone is amorphous, there is little physical property deterioration by temperature rise, and since the temperature dependence of flexural modulus is small, it hardly changes at -100-200 degreeC. Load distortion temperature is 200-220 degreeC, and glass transition temperature is 225 degreeC. In addition, the creep resistance up to 180 ยฐ C. is the best among thermoplastic resins, and has the property of withstanding hot water or steam of 150 to 160 ยฐ C.

It is usually expressed in terms of viscoelasticity per cut area and the unit is dynscm-2gcm-1s-1 or poise (P). The viscosity decreases in inverse proportion to the temperature rise. The viscosity of the solution is higher than that of the solvent because the flow of the liquid is skewed depending on the solute, and the flow rate of the liquid is reduced by that amount.

K and a at this time are integers which depend on a kind of a solute or a solvent, and temperature. Therefore, the viscosity value is affected by temperature and the degree of change depends on the type of fluid. Therefore, when talking about viscosity, you must specify the values of temperature and viscosity.

That is, the physical properties of the polymer (polymer solution) radiated by electrospinning is important. In general, the viscosity of the polymer during electrospinning has been considered necessary to maintain a certain viscosity or less. This is due to the property that the higher the viscosity, the spinning of the nano-thickness fibers through the nozzle is not made smoothly, the higher the viscosity is not suitable for the fiber through the electrospinning.

By calculating the thickness of the long sheet 15 in which the nanofiber nonwoven fabric is laminated from a predetermined equation using the propagation speed and the temperature constants of the longitudinal wave and the transverse wave propagation speed, the propagation speed according to the temperature change even when the internal temperature is uniform. The thickness can be precisely measured by self-compensating the error caused by the change, and the precise thickness can be measured regardless of any type of temperature distribution inside the filter.

Thereby preventing the detachment phenomenon occurring in the second nanofibrous layer which is electrospun onto the first nanofiber layer and the first nanofibrous layer, and the third nanofibrous layer which is electrospun onto the second nanofiber layer and formed to be laminated. By spraying the adhesive (low melting point polymer) only to specific regions and portions of the 1 nanofibrous layer and the second nanofiber layer, the injected adhesive (low melting point polymer) minimizes interference of the polymer spinning solution electrospun, thereby It can improve performance and quality.

In the present invention, as the polyvinylidene fluoride (PVDF) polymer, it is preferable to use a polyvinylidene fluoride (PVDF) copolymer having a comonomer content of 5 to 50% by weight. The comonomer is tetrafluoroethylene (TFE), trifluoroethylene, hexafluoroisobutylene, perfluorobutyl ethylene, perfluoro, in addition to hexafluoropropylene (HFP) or chlorotrifluoroethylene (CTFE). Low profile vinyl ether (PPVE), perfluoro ethyl vinyl ether (PEVE), perfluoro methyl vinyl ether (PMVE), perfluoro-2,2-dimethyl-1,3-dioxol (PDD) and perfluor Rho-2-methylene-4-methyl-1,3-dioxolane (PMD) and the like may be used, and among these, hexafluoropropylene (HFP) or chlorotrifluoroethylene (CTFE) may be preferably used. However, it is not limited to this kind.

In the present invention, the weight average molecular weight of the polyvinylidene fluoride (PVDF) polymer having a melting point of 80 to 160 ยฐ C is 3,000 to 30,000. It is desirable to adjust. If the weight average molecular weight exceeds 30,000, the melting point exceeds 160 โ„ƒ, if less than 3,000 melting point is less than 80 โ„ƒ bar efficiency of electrospinning is inferior.

Thereafter, the spinning solution was moved from the main tank 8 to the nozzle block, and the distance between the nozzle block and the collector was 40 cm and the electrospinning voltage was 25 kV. After the spinning process, the solids, which could not be spun and overflowed, were returned to the main storage tank, which is one of the storage tanks, and the concentration of the spinning solution in the main tank was changed to 15%. Accordingly, the viscosity was changed to 2000 cps.

Thereafter, the spinning solution was moved from the main tank 8 to the nozzle block, and the distance between the nozzle block and the collector was 40 cm and the electrospinning voltage was 25 kV. After the spinning process, the solids, which could not be spun and overflowed, were returned to the main storage tank, which is one of the storage tanks, and the concentration of the spinning solution in the main tank was changed to 15%. Accordingly, the viscosity was changed to 2000 cps. Thereafter, the temperature of the main tank was raised to 70 ยฐ C. in order to lower the viscosity to 1000 cps by a sensor of a thermostat, followed by electrospinning to obtain nanofibers.
