Description
The present invention relates to a sound absorbing fabric for absorbing and extinguishing noise. More particularly, the present invention relates to a weft yarn and a weft yarn woven by weaving yarns and warp yarns, Sound absorbing fabric capable of adjusting the sound absorption properties by combining wool yarns as weft yarns or warp yarns by combining the yarns at a proper ratio.
Sound absorbing materials are mainly used in facilities such as buildings, vehicles or sound facilities.
In addition, there are two ways to improve the noise. One is improving the sound absorption and improving the sound quality. Sound absorption is the sound energy that is transmitted through the inner path of the material and is converted into heat energy and disappears. Is reflected and shielded by the shield.
That is, the term " sound absorption " means that part of the sound incident on the material is absorbed in the material without being transmitted or reflected. When sound is generated from one side of a material, the sound that is not reflected corresponds to the material being absorbed or permeated. Since the sound that is not reflected as such appears to be absorbed, the ratio of the sound energy that appears to be apparent absorption to the incident sound energy is called the sound absorption rate. The sound absorption rate differs depending on the frequency of the sound, the incident angle, the thickness of the material, the installation method, and the situation on the back of the material.
Also, sound insulation refers to the fact that sound vibrations are not transmitted to the outside, and it is generally expressed in decibels (dB) dB = 20 log m + 20 logf -23 (m is the unit area gram mass and f is the negative frequency) .
The wall, ceiling and flooring materials used for indoor construction should have sound absorption and sound insulation function first. There is a noise preventing agent proposed in Korean Patent Laid-Open Publication No. 10-2005-0007353 as a related art related to soundproofing and noise. The prior art includes a soundproof plate having at least one soundproof hole recessed therein; A cover plate coupled to an upper portion of the soundproofing plate to shield soundproofing holes; A noise preventing agent comprising a soundproof panel accommodated in a soundproofing plate of a soundproofing plate body and having a noise preventing effect. In the above-mentioned prior art, EVA (Ethylene Vinyl Acetate Copolymer), expanded polystyrene, rubber plate or urethane is used as a soundproofing material, and a nonwoven fabric, a cotton wool, a cork or a loess is used as a sound absorbing material.
The above-mentioned prior art is insufficient in that a sound-absorbing material is present inside the sound-absorbing material or sound-absorbing material is used by using a separate material.
In addition, since a conventional sound absorbing material is formed so as to form a predetermined bend on the surface of a sound absorbing material such as a nonwoven fabric, and to eliminate the sound that is incident using the refraction and reflection phenomenon of sound, research on a sound absorbing material Development is required.
The present invention relates to a sound absorbing material for absorbing and extinguishing noise, which is intended to solve the problems of the related art. Conventional sound absorbing materials simply form a certain bend on the surface of a sound absorbing material such as a nonwoven fabric, There is a problem that the structure for forming the bending on the surface of the sound absorbing material must be installed in the lower portion of the sound absorbing material in advance;
Even if the structure is appropriately curved, the sound-absorbing material for absorbing and extinguishing sound mainly has insufficient sound-absorbing property, so that there is a problem that the effect of sound-annihilation is insufficient.
The sound absorbing material must have a sound absorbing property capable of extinguishing the noise in the appropriate frequency range depending on the use purpose in which the sound absorbing material is installed. However, the conventional sound absorbing material having a unified structure has a problem that it can not be appropriately selected and used according to the use purpose of the sound absorbing material. The main objective is to provide a solution.
The present invention has been made to solve the above-

As described above, the high sound-absorbing and sound absorbing fabrics according to the present invention are made by weaving yarns and warp yarns having different thicknesses using weft yarns and warp yarns of a sound absorbing fabric. Therefore, by using the warp yarns and the weft yarns, The effect of easily absorbing and extinguishing noise can be obtained;
As a result, there is no need to provide a separate structure for forming a curvature on the surface of the sound absorbing fabric;
By adjusting the thickness of the weft and weft yarns and adjusting the ratio of the weft yarns to the weft yarns of the weft yarns to adjust the number and size of the porous yarns of the weft yarn fabrics, An adjustable effect can be obtained;
Also, it is possible to obtain the effect of ensuring stability against fire by imparting flame retardancy;
The effect of attaching the aesthetics of the sound absorbing fabric can be obtained through various tissue patterns formed on the surface of the sound absorbing fabric.

2 is a photograph showing a weaving structure of a high sound-absorbing sound absorbing fabric according to a preferred embodiment of the present invention.
The present invention relates to a sound absorbing fabric for absorbing and extinguishing noise, which is made by weft yarn and weft yarn, wherein the weft yarn and the warp yarn are formed by joining a plurality of short yarns and a plurality of long yarns, The present invention relates to a high sound-absorbing sound absorbing fabric composed of a single filament.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to FIGS. 1 and 2 showing embodiments of the present invention.
First, the main purpose of the sound absorbing fabric according to the present invention is to reduce noise by extinction in a manner of absorbing noise. Also, the meaning of reducing the noise as described above includes an effect of preventing sound generated from a certain size from being heard from the outside to the inside or flowing out from the inside to the outside.
Also, the sound-absorbing fabric according to the present invention is manufactured in such a manner that the weft yarns and the warp yarns are cross-woven as shown in FIG. 1, wherein the weft yarns and weft yarns used as warp yarns and weft yarns are different in thickness.
In other words, although the thick yarn is generally thicker than the cedar yarn, it is preferable to use a yarn in which a plurality of short filaments shorter than the cedar yarn are folded in the present invention.
Specifically, it is preferable that the web is made of 2 to 10 ply of staple fibers having a fiber diameter of 1 to 10 deniers and a length of 20 to 80 mm.
At this time, if the thickness of the staple fibers for making the staple fibers is less than 1 denier, the thickness of the staple fibers becomes excessively thin. When the staple fibers have a diameter exceeding 10 deniers, the thickness of the staple fibers is excessively thick. There is a possibility that the thickness of the fibers becomes thick. Therefore, it is preferable that the thickness of the fibers for forming the false teeth is kept within the above range.
Also, if the length of the fibers for making the false teeth is less than 20 mm as described above, there is a possibility that the thickness of the sound absorbing fabric to be finally produced is difficult to control and the sound absorption performance is lowered. If the length exceeds 80 mm, There is a possibility of difficulty in controlling the thickness of the fabric. Therefore, it is preferable to use short fibers within the above-mentioned range for the length of the fibers for making the false teeth.
In addition, it is preferable that the staple fibers having the above-mentioned thicknesses and lengths are folded to 2 to 10 ply and made into a false lap. That is, the tassel is a yarn made by twisting short fibers of the above-mentioned thickness and length into two to ten strands, and as the number of strands is increased, the texture of the tassel becomes dense and the thickness of the tassel becomes thicker.
That is, the number of folds of the false-twisted yarn can have a folding number of 2 to 10 ply depending on the use of the manufactured sound-absorbing fabric. The number of the pores formed between the weft and the warp, By adjusting the size, it is possible to obtain the effect of varying the frequency band of the extinction noise.
In addition, although the thread is generally shorter than the thread thread as is generally known, in the present invention, it is preferable to use a thread thread having a plurality of long threads longer than the thread thread.
Specifically, it is preferable that the yarns are composed of 1 to 3 plies of DTY (Draw-textured yarn) or ATY (air-jet textured yarn) yarn having a fiber thickness of 150 to 300 denier.
At this time, if the thickness of the fiber for making the fleece is less than 150 denier, the thickness of the fleece made of the excessively thin fiber becomes excessively thin. If the fiber thickness exceeds 300 denier, the thickness of the fleece is excessively thick, Therefore, it is preferable that the thickness of the fiber for forming the fleece is kept within the above-mentioned range.
Also, it is preferable to use a yarn obtained by folding DTY (Draw-textured yarn) or ATY (air-jet textured yarn) processed yarn at 1 to 3 ply. The drawn yarn (DTY) The air-jet textured yarn (ATY) is made of a composite yarn manufacturing technique for forming bulkiness and porosity by generating fine hairs and loops such as natural fibers using an air nozzle in an ATY machine. It is thread.
In addition, it is preferable that the above-mentioned yarn is produced by folding the processed yarn of the above-mentioned constitution in a single yarn (1ply) to 3ply. That is, the number of pores formed between the weft and the slope can be controlled by varying the thickness of the fleece according to the change of the number of flecks, thereby obtaining the effect of varying the frequency band of the extinct noise.
The weft yarns and weft yarns of the above-described structure are used as weft yarns and weft yarns of weft-absorbing woven fabrics. In this case, weft yarns and weft yarns used in weft yarns are different from weft yarns used in weft yarns, The number and size of the pores can be adjusted, and the aesthetics of the woven sound absorbing fabric can be improved.
In addition, the present invention can adjust the weft and warp ratio of the warp or weft of the sound absorbing fabric to be woven.
Specifically, the ratio of the weft yarns used as weft yarns may be 1: 5: 1 ~ 2, and the ratio of weft yarns used as weft yarns may be 1: 5: 1 ~ 2. In other words, the weft is used so that one to five weft yarns are used, and one weft yarn is positioned after the continuous weft yarns are used. In this case, one to five yarns are used as a warp yarn so that one or two yarns So that a sound absorbing fabric can be made.
The sound absorbing fabric which is formed by weft and warp formed with weft and warp in the above configuration is formed between warp yarn used as weft yarn and false yarn formed between warp yarn and warp yarn, The number and size of the pores formed between the weft and the warp formed by the pore and the weft and the weft formed between the weft and the warp formed by the pore, the weft, and the weft can be variously controlled.
In addition, the number and size of the pores of the sound-absorbing fabric, which are varied in the ratio of the weft and the weft yarn used for weft yarns and warp yarns as described above, can absorb and dissipate noise in various frequency band zones. The sound absorbing ability of the sound absorbing fabric is improved and the sound absorbing fabric according to the present invention can be used for various use purposes. The change in the texture pattern of the sound absorbing fabric, Sound absorbing fabrics can be produced.
In addition, the sound-absorbing fabric according to the present invention may be structured such that weft yarns and warp yarns of the surface weaving layer and the back sheet weaving layer are weaved at a ratio of the weft yarns and the weft yarns to form different patterns.
That is, the patterns of the surface-woven layer and the back-woven layer of the sound-absorbing fabric are formed differently, meaning that the positions, the number and the sizes of the pores formed in the porous and back-woven layers formed in the surface weaving layer may be different, Noises incident on the surface weaving layer are primarily absorbed in the pores formed in the surface weaving layer and part of the noise that has not been lost in the surface weaving layer is absorbed secondarily in the pores formed in the backing layer and can be annihilated .
The weft yarns constituting the surface weaving layer and the back weaving layer may be formed in various forms according to the judgment of a person skilled in the art. More preferably, both the surface weaving layer and the back weaving layer It is preferable that the ratio of the weft yarns and the weft yarns constituting weft yarns or weft yarns is in the range of 1: 5: 1 to 2:
In addition, the short fibers or long fibers forming each of the false-twitch yarns and the short fibers may be made of a polyester material, and the short fiber or long fiber may be impregnated or coated with a phosphorus-based flame retardant.
That is, when the flame retardant is impregnated or coated on the short fibers or the long fibers, which are the raw materials of the false-twist yarn and the fine yarn woven with the sound-absorbing woven fabric as described above, the sound-absorbing fabric to be produced has the flame retardancy.
In addition, as described above, when the flame retardant is applied to the short-fiber or long-fiber, which is a raw material of the first and second fibers, by directly impregnating or coating the flame retardant with the flame retardant, The flame retardant can be further effectively injected into the sound-absorbing fabric to further improve the flame retardancy.
At this time, any one or more of the inorganic flame retardant and the organic flame retardant may be used as the flame retardant, but it is more preferable to use a phosphorus flame retardant among the organic flame retardant.
That is, the phosphorus-based flame retardant is a flame retardant that prevents decomposition in the condensation phase and increases the degree of carbonization to perform a flame retarding action. As a flame retardant, generally known ones can be used, but ammonium phosphate, ammonium polyphosphate, Phosphate or the like is preferably used.

1. Sound absorption rate
1) Sound absorption rate test method
① Test method: In-house method (KS F 2814)
② Measuring equipment: Sound Absorption Tester
③ Measurement frequency: 200 ~ 5000Hz
The in-tube method is a method of measuring the sound absorption rate of a sound-absorbing material, which is obtained by measuring a standing wave when a plane wave is vertically incident in a certain direction. In addition, it is possible to obtain the result of minimizing the measurement error by repeatedly testing the specimen with a simple method that can be tried when it is difficult to secure the specimen.
o NRC = (? 250 +? 500 +? 1,000 +? 2000) / 4
(?: sound absorption rate of X Hz)
That is, since the sound absorption ratio of the sound absorbing material is different for each frequency, the NRC (Noise Reduction Coefficient) refers to a single index of the sound absorption rate which represents the material of the sound absorbing performance. A single exponent is called an NRC. In this test, the frequency relative to the frequency was measured with the rear space of 50 mm.
In addition, the specimens were the sound absorbing fabrics Examples 1 to 3, the conventional curtain fabric Comparative Example 1, and the conventional nonwoven fabric Comparative Example 2, which were manufactured by the present invention, and the results are shown in Table 1 below.
2) Test result
As shown in Table 1, the sound-absorbing fabrics according to Examples 1 to 3 according to the present invention were far superior to the curtain fabric according to Comparative Example 1 and the non-woven fabric according to Comparative Example 2, respectively.
