Description

Apparatus and method for manufacturing web media using PET or PPP-based low melting staple fiber TECHNICAL FIELD

The present invention relates to a web media manufacturing apparatus using a PET or PP low melting point staple fiber, and a method of manufacturing the same.

As the industry develops today, fine dusts, odors, and toxic gases in the air are harmful to the human body, and the main components thereof include nitrogen-based compounds of ammonia and amines, and lower hydrocarbons such as toluene, styrene, and isoprene. Compounds and sulfur compounds such as hydrogen sulfide, mercaptan and dimethyl sulfide.

In order to solve the damage caused by the odor and toxic gas containing sulfur compounds harmful to the human body as described above, a filter media using activated carbon having excellent performance in adsorption and removal of odorous substances or specific substances has been proposed. Filter media using the activated carbon are widely used in mask filters, automotive cabin filters, air purification filters, semiconductor clean rooms, and air conditioning filters.

As a conventional method for producing filter media using the activated carbon, a honeycomb extrusion method is formed by mixing activated carbon and a polymer adhesive, and a thermal fusion method for forming activated carbon by heat fusion to a nonwoven fabric, an adhesive and a resin. There is a hot melt (Hot-Melt) method and a binder (Binder) method that is formed by mixing and spinning and supplying activated carbon to one side.

However, the honeycomb extrusion method has the advantage of using the adsorption performance of activated carbon to the maximum, but there are technical difficulties in the honeycomb molding and its economical problems. The disadvantage is that it is very limited.

In addition, in the case of the thermal fusion method, since the product is manufactured by heating the nonwoven fabric or the like, there is a problem that degradation of the circular shape of activated carbon, thermal deformation of the adsorbent, and deterioration of the adhesive are caused. There is a problem in that the weight of the activated carbon is not uniformly laminated on the nonwoven fabric, and thus, the adhesion force of the activated carbon is weak, resulting in detachment from the nonwoven fabric.

In addition, the hot-melt method or the binder method is formed by spinning a resin mixed with an adhesive and supplying activated carbon to one side, thereby making it difficult to distribute the activated carbon uniformly in the resin. The surface of the activated carbon is in a state in which the characteristic of the activated carbon is not only lowered, but also the differential pressure is also increased, thereby degrading the performance of the filter media.

In addition, the hot-melt method or the binder method is a method in which the adhesive or the melted resin is pressed before it is hardened to produce a finished product. There is a problem that the purification function is reduced by preventing pores associated with the purification function of the hardened filter media, and the manufactured filter media has an overall hard texture (characteristic), so that the formability of shapes such as altar and bending is not easy. have.

Specifically, the carding machine 32 is driven by the rollers 32a formed with a plurality of needle rods 32b disposed adjacent to each other, and a fiber opened between the driven rollers 32a is used to drive the rollers 32a. In the same principle as combing by the needle rods 32b while moving along, the fibers B separated and aligned one by one are formed as slivers 1.

The sliver stacking step (S300) is to stack the sliver 1 formed in the sliver forming step (S200) on a first sheet 11, and the first sheet 11 supplies a first sheet. The sliver 1 formed by the carding machine 32 disposed above the conveying belt 20 is transported after being unloaded from the roller 10 and seated on the conveying belt 20. By being discharged to the lower side of the carding machine 32, the stack of the sliver 1 on the first sheet 11 can be made. In addition, when the sliver 1 is stacked on the first sheet 11, the sliver 1 is stacked in a direction of the transport belt 20 as shown in FIG. 7. In addition, by controlling the discharge amount of the sliver 1 by controlling the speed of the carding machine 32, it is possible to adjust the formation thickness of the web media (C).

The activated carbon stacking step (S400) is performed after the sliver stacking step (S300). The activated carbon stacking step (S400) is to supply and stack the activated carbon 2 on the first sheet 11 on which the sliver 1 is stacked, wherein the supply of the activated carbon 2 is a first hopper It is made by the activated carbon supply part 40 comprised by the 41 and the 2nd hopper 42 which supplies a predetermined amount of activated carbon to the said 1st hopper 41. FIG.

The first hopper 41 has a bottom surface formed of a mesh net 43, and a first vibrator 41a is provided at one side thereof, so that the activated carbon 2 supplied from the second hopper 42 is transferred to the sliver ( 1) may be uniformly supplied and laminated on the laminated first sheet 11. The supply (discharge) rate of the activated carbon 2 is controlled by adjusting the set amount of the activated carbon 2 supplied from the second hopper 42 or by adjusting the intensity of vibration of the first vibrator 41a.
