Description
The present invention relates to a nonwoven fabric for an air filter support having excellent air permeability and improved napping and peel strength and a method of manufacturing the same. More particularly, the present invention relates to a nonwoven fabric for an air filter support which maximizes air permeability, To a nonwoven fabric for an air filter support, which improves strength and improves bonding with various materials that maintain static pressure for a long time and impart filter performance, and a method for manufacturing the same.
The air filter, in particular a cabin air filter for a car or a cartridge filter for an air purifier, can be used when the outside air is introduced into the room during the heating and cooling of the vehicle or when the indoor air purifier is operated, , Which is usually classified into electrostatic type filters that filter particles and combination filters that add antibacterial and deodorizing effects.
These two types of filters are basically composed of a support-membrane-separating layer-activated carbon (no electrostatic type) -strate, although it is different depending on which layer contains the structure or electrostatic treatment. At this time, the membrane is responsible for filtering the particles, and the activated carbon layer is responsible for removing the toxic gas. However, the role of maintaining the shape of the filter material to perform the function and maximizing the surface area of the filter to improve the filtration efficiency, and maintaining the appropriate porosity to constantly maintain the differential pressure, The material of the filter support body is taken care of. Accordingly, the nonwoven fabric material is a typical example of a material capable of exhibiting physical characteristics in accordance with the above purposes and offering price competitive price to consumers through mass production. For example, conventionally, short fibers of 20 to 100 mm were carded to form a support structure through thermal bonding. However, since the above-mentioned material lacks mechanical properties and workability, it is not suitable as a support for a conventional air filter, There is a problem that the productivity is lowered by a multi-step process.
For example, Korean Patent Laid-Open Publication No. 2005-0062134 entitled " Polyester Spunbond Nonwoven Fabric for Air Filter Support and Method for Producing the Same " (First component) having a melting point of at least 250 캜, and a polyester copolymer (second component) having a melting point lower than that of the polyester by 20 to 130 캜, wherein the fibers constituting the nonwoven fabric have a diameter of 20 A polyester spunbonded nonwoven fabric for an air filter support and a method for producing the same. However, the above method does not describe how to solve the fluff or peeling which may cause a fatal problem in the filter manufacturing process when the conditions are not optimized when the low melting point polymer is combined. Korean Patent Laid-Open Publication No. 2010-0077512 also discloses that "a polyester fiber material is spun as a hollow needle having a circular or elliptical cross section to form a polyester hollow filament having a single filament diameter of 22 to 40 μm, Polyester hollow spunbond nonwoven fabric for air filter in which a laminated web is heated and pressed ". However, the method is advantageous in that it is made of a polyester hollow filament having a uniform single-filament diameter and is excellent in bulky property, air permeability and workability, and is continuously produced by a single process to greatly improve productivity. However, There is a point to be improved.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic cross-sectional view of a detaching arrangement used for the production of filaments in accordance with a preferred embodiment of the present invention.
Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. However, it should be understood that the following preferred embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention.
The nonwoven fabric for an air filter support having an excellent air permeability and improved napping and peel strength according to the present invention can have a single layer structure or a multilayer structure and can be constituted by hot pressing at a constant pressure and a constant temperature .
The nonwoven fabric for an air filter support having improved napping and peel strength with excellent air permeability according to the present invention has an intrinsic viscosity of 0.5 to 0.9, a polyethylene terephthalate of a first component having a melting point of 240 to 260 ° C and an intrinsic viscosity of 0.5 to 0.9 (Hereinafter referred to as a first component and a second component, respectively) having a melting point of 210 to 230 ° C are dried / crystallized so that the first component is used as a core and the second component is used as a sheath Spinning is carried out using specially designed sleeves capable of complex spinning in the form of sheath / core and at the same time capable of spinning filaments of minimum 6 to maximum 13 denier.
According to a preferred embodiment of the present invention, the ratio of the second component to the first component constituting the nonwoven fabric according to the present invention is preferably 3 to 50 wt%. If the weight ratio of the second component is less than 3% by weight, the bonding strength of the nonwoven fabric sharply decreases. If the weight ratio of the second component is more than 50% by weight, the spinning may not be performed smoothly.
According to another preferred embodiment of the present invention, it is particularly preferable that the weight per unit area of the nonwoven fabric is 30 to 110 g / m 2.
According to another preferred embodiment of the present invention, the fineness of the fibers constituting the nonwoven fabric is preferably at least 6 to at most 13 denier, and the air permeability of the nonwoven fabric is preferably 200 cc or more.
According to a preferred embodiment of the present invention, filaments radiated through the nip are controlled to have a fineness of 6 to 13 denier by controlling the amount of discharge and the amount of drawing by the air pressure of an ejector to uniformly open the filaments Are collected on a continuously moving porous conveyor belt to form a web. Particularly, as in the present invention, when the discharge amount per hole is maximized to emit more than 6 denier yarns, uniform mixing of the filaments directly affects the uniformity of the yarn. Therefore, So that the dispersibility of the filament is maximized.
The nonwoven web collected on a porous conveyor is first pre-bonded through a thermal calender, and is then given the minimum strength and form stability necessary for the subsequent continuous bonding process. At this time, the conditions of the thermal calenders used for pre-bonding have a definite effect on the air permeability and fluff, which are the physical characteristics of the nonwoven fabric for the air filter support having the air permeability and improved napping and peeling strength, You need to decide. The conditions of the thermal calenders used for the prebonding were most improved at 160 ° C to 170 ° C. The primarily pre-bonded nonwoven web is then transferred to the heating drum through the porous conveyor. In the heating drum, the first pre-bonded tanned nonwoven web is bonded with a strong hot air. In this case, the second component of the cocoa type filament constituting the nonwoven web sufficiently melts and fuses to each other If the temperature exceeds 230 ° C, the fused area of the filaments is widened, and the air permeability may be drastically deteriorated. The nonwoven web finished from the first calender prebonding and the second hot air bonding at the above temperature is finally embossed by embossing the embossing rolls of high-temperature and high-pressure embossed in various forms to minimize the fluff generated during the processing, The peeling strength which can be insufficient can be improved to provide an optimum filter support. The processing conditions of the embossing roll according to the present invention are 200 to 210 ° C and the line pressure can not exceed 40 kg / cm. When the processing conditions of the embossing roll exceed the above-mentioned range, the air permeability of the nonwoven web rapidly drops and the function of the filter support is lost, which is not preferable.
Hereinafter, the present invention will be described in more detail with reference to examples, but it goes without saying that the scope of the present invention is not limited to these examples.
Measurement and evaluation values of various characteristics in the following examples were analyzed by the following methods, and the results are shown in Table 2 below.
(1) Air permeability: The amount of air flowing vertically through a certain area of the nonwoven fabric was measured using an orifice (circular test piece holding device) capable of testing an area of 38 cm 2 by the KS K 0570 method.
(2) Inner friability: The manufactured nonwoven fabric samples were blind tested by 10 nonwoven fabric development experts and scored and evaluated. 9: No lint, 5: Pre-improvement level, 1: Lint can not be used.
(3) Peel evaluation: After the prepared nonwoven fabric sample was cut to 50x200 in the MD direction, it was evaluated whether it could be separated into two or more layers by hand. If it can be peeled more than 2 times in 3 samples, peeling occurs. If it can be peeled less than 1 time, it is marked as no peeling.

The fineness of the spun filament is adjusted to about 11 denier according to specially designed tanned needle and cooling stretching conditions. The temperature of the cooling air used is 15 ℃ and the spinning speed is about 4,000 m / min. The nonwoven web laminated on the porous conveyor is subjected to heat calendering and hot wind bonding according to the conditions shown in the following Table 1 and finally subjected to an embossing bonding process. All the production conditions used in Examples 1 to 9 were carried out while fixing all conditions such as line speed and total discharge amount except for the thermal calendering, hot air blowing and embossing conditions shown in Table 1 below.
