  The present invention relates to a sheet-like fabric having a deodorizing effect due to odor adsorption, and more specifically, installed on ceilings of indoor stadium facilities, gymnasiums, indoor pools, event halls, public halls, ceremonial occasions, station buildings, airports, shopping malls, etc. As a ceiling area component membrane material (membrane ceiling), ceiling accessories (aerial membrane), banners, banners, and in food factories, chemical factories, livestock farming facilities, fishery facilities, garbage disposal facilities, etc. For wall hangings, rugs, aerial membranes, and odorous components such as awning tents, blinds, tapestry, for indented / clogged boxes, toilet mats / tapestry, kitchen mats, etc. Deodorizing effect that effectively reduces the concentration in a well-balanced manner, and deodorizing effect that reduces to the human perception limit concentration over time Expressing relates deodorizing fabrics capable of expressing a sound absorbing property by the application.

  First, the applicant of the present invention applied the odor molecule to the thermoplastic resin layer of a flexible mesh sheet having a specific filling rate and unit surface area, which is composed of a coarse woven fabric and a thermoplastic resin layer covering the coarse woven fabric. On the other hand, by arbitrarily using odor molecule deactivating particles such as an inorganic porous material having physical adsorptivity, an inorganic oxidizing / reducing material having chemical reactivity, and an inorganic decomposition reaction catalytic material, body odor, pet The mesh sheet (patent document 1) which attached the function to reduce the whole life odors, such as an odor, cooking odor, garbage odor, and mold odor, was proposed. Patent Document 2 discloses a basic, sulfur-based and acidic malodorous component including four major malodorous components (ammonia, trimethylamine, hydrogen sulfide, and methylcaptan) and an odor eliminating effect that exerts a deodorizing effect on aldehyde compounds. As a method for producing odorous fiber products, (A) a composite of silicon dioxide and zinc oxide, (B) a composite of amorphous silica and / or silica alumina and phyllosilicate and / or aluminum phyllosilicate (C) A method of applying a dispersion containing a polyhydrazide compound and (D) a polycarboxylic acid and / or a salt of polycarboxylic acid to a fiber material is disclosed. In these Patent Documents 1 and 2, in order to cope with various types of odor molecules, it is essential to use a plurality of chemical substances or adsorbent substances that are compatible with acidic malodor components and basic malodor components. Although the tests for individual odors in the examples show good results, verification of the deodorizing effect and deodorizing effect on complex odors such as living odors has not been made. By the way, the more combined types of chemical substances and adsorptive substances with different characteristics, the more often they interfere with each other. For example, if there is a chemical substance bound to an acidic malodorous component first, the removal of the basic malodorous component will be insufficient or adsorbed by slowing the action of the chemical substance binding to the basic malodorous component. Inhibits the action of other deodorizing ingredients and adsorbents, such as promoting the release of malodorous ingredients, resulting in sustained deodorizing and deodorizing effects on the intended life odor (complex odor). There is a glimpse of the reality that cannot be obtained. Therefore, in Cited Document 3, as a honeycomb filter that enhances the deodorizing effect due to a single gas passage for a plurality of types of bad odors, the corrugated sheet is changed from an integrated sheet in which a basic gas adsorbing sheet and an acid gas adsorbing sheet are bonded and arranged. Although a honeycomb structure in which a flat sheet is made and corrugated sheets and flat sheets are alternately laminated is disclosed, this honeycomb structure naturally has a box shape as shown in FIG. Use in living spaces such as wall materials and partitions is inconvenient because it is bulky and affects the space and appearance.

When the weaving / knitting element is 1) a warp yarn group and a weft yarn group, the yarn (A) having an acid odor adsorbing resin coating layer as the outermost layer in both groups, and the basic odor adsorbing resin coating layer as the outermost layer A mode comprising yarns (B) having a regular alternating arrangement or random arrangement, or a yarn (A) having an acidic odor adsorbing resin coating layer as an outermost layer in a warp group, and a basic odor adsorbing resin coating A mode in which the yarn (B) having the outermost layer is properly used for the weft yarn group, or a mode in which the yarns are opposite to each other can be exemplified, and each of these modes is a single layer fabric, a double fabric, or a triple fabric. It is. Similarly, in the case of the knitting and knitting element 2) as the triaxial woven fabric, and the warp yarn group and the upper left and upper right bias yarn groups, the yarn having the acid odor adsorbing resin coating layer in the outermost layer in both groups. (A) and an embodiment comprising a yarn (B) having a basic odor adsorbing resin coating layer as an outermost layer in a regular alternating arrangement or a random arrangement, or a yarn having an acidic odor adsorbing resin coating layer as an outermost layer A mode in which (A) is used for the warp yarn group, a yarn (B) having a basic odor adsorbing resin coating layer in the outermost layer is properly used for the bias yarn group, or the opposite usage mode can be exemplified. In the case of any one of the single layer woven fabric, the double woven fabric, and the triple woven fabric, the value when the sum of the pore gaps at the woven / knitting intersection points of the woven / knitting elements 1) and 2) is defined as the porosity is 5% or less Is preferred. When sound enters the hole gap, resonance vibration occurs at a specific frequency, air vibrates in the hole gap, and sound energy is attenuated. Therefore, the hole diameter of the hole gap is in the range of 0.05 to 1.0 mm. Preferably, the number of hole gaps is in the range of (vertical 8 × horizontal 8) to (vertical 60 × horizontal 60) /25.4 mm ² , especially ( vertical 12 × horizontal 12) and - (33 × width 33 length) of 25.4 mm ² peak higher the sound absorbing effect. The amount of air passing through the pore-shaped gap is 5 to 100 cc / cm ² / sec (JIS L1096: Frazier method), and particularly 10 to 50 cc / cm ² / sec is the gas exchange for the expression of the sound absorption effect and the deodorization effect. Excellent in properties and preferable.

Single-layer fabrics are plain fabrics, 2/2 Nanako (basket) fabrics, 2/2 cocoon fabrics, twill fabrics: 2/1 twill fabrics, 2/2 twill fabrics, 3/1 obliques (four sheets twill), 3 / 1 Torn text (4 sheets Aya), 3/2 Text (5 sheets Aya), 4/1 Text (5 sheets Aya), 5/1 Text (6 sheets Aya), 4/2 Text ( 6 sheets Aya), 1/3/1, 1 Oblique (6 sheets Aya), etc. Ako fabric: 2 jump 4/1 Auko (5 sheets Ako), 3 jump 4/1 Auko (5 sheets Auko), 2 jumps 3/2 Auko (5 sheets Auko), 3 Jump 3/2 Auko (5 sheets Auko), etc., and these changed plain fabrics, changed twill fabrics, changed satin fabrics, honeycomb fabric, pear fabrics, tearing obliques textile, day and night satin product, twisting the fabric (gauze fabric, Roori thereof), Nuito fabrics, such as Russell knitting can be used, they are mass 0.2~1.2kg / ^{m 2,} void ratio of 5% or less (textile intersection Of hole-like gaps Occupancy), and the air permeability of the sum (JIS L1096: Frazier method) 5~100cc / cm ² / sec to satisfy the is illustrated, gas exchange for expression and deodorizing effect expression of sound absorbing effect by the air permeability Excellent.

The double woven fabric is a woven fabric that overlaps the upper and lower two sheets using the front and back warp yarns and the front and back weft yarns, and the upper fabric has a porosity of 10 between the front warp yarn and the front weft yarn. % Or less (occupation ratio of the total pore clearance generated at the weaving and knitting intersection), and the lower woven fabric has a porosity of 10% or less between the back warp and the back weft (total of the pore clearance generated at the weaving and knitting intersection) ), A mass of 0.4 to 2.4 kg / m ² , a shared porosity of 5% or less (occupation ratio of the sum of overlapping portions of hole-like gaps generated in stacked fabrics), and air permeability ( Examples are those satisfying JIS L1096: Frazier method) 5 to 100 cc / cm ² / sec. Similarly, the upper and lower fabrics are overlapped using upper / lower warp and front / back warp bias yarns, and the upper fabric has a porosity of 10% between the front warp and the front warp yarn. The following is made up (occupation ratio of the sum of the hole gaps generated at the weaving and knitting intersections), and the lower fabric has a void ratio of 10% or less between the back warp and the back diagonal threads (the sum of the hole gaps occurring at the weaving and knitting intersections) ), A mass of 0.4 to 2.4 kg / m ² , a shared porosity of 5% or less (occupation ratio of the sum of overlapping portions of hole-like gaps generated in stacked fabrics), and air permeability ( Examples are those satisfying JIS L1096: Frazier method) 5 to 100 cc / cm ² / sec. If the air permeability is less than 5 cc / cm ² / sec, the adsorption and collection efficiency of odor molecules may be lowered and the sound absorbing effect may be deteriorated. The common void ratio is that the sound-absorbing membrane material is placed horizontally, and when this is observed from the vertical direction, the void portion of the upper fabric and the void portion of the lower fabric overlap each other and pass through the two fabrics. Is the occupancy rate per unit area. In other words, the upper woven yarn is arranged to overlap the lower woven fabric gap, or the lower woven yarn is arranged to overlap the upper woven void, and the shared porosity becomes a small value, Apparently 0 depending on the degree of overlap. A warp double woven fabric is composed of a set of weft and warp warps and warp warps, and an extra warp thread is woven on the back of a single woven fabric. 2: 1, 3: 1, etc. A weft double woven fabric consists of a set of warps and wefts with a weft and back weaving and a single weaving with another weft, and the arrangement of wefts and wefts is 1: 1, 2: 1, 3: 1 and so on. The background double woven fabric is obtained by weaving two woven fabrics with the same loom, and connecting the upper and lower two woven fabrics (with a mass of 0.4 to 1.2 kg / m ² ) with the yarns.

Similarly, a triple woven fabric is a woven fabric in which three upper, middle, and lower fabrics are stacked using front, middle, and back warp yarns and front, middle, and back weft yarns. Each of the woven fabric and the lower woven fabric is composed of a void of 10% or less (occupation ratio of the total pore-shaped gap generated at the knitting intersection), and a mass of 0.2 to 1.0 kg / m ² , and a mass of 0.6 to 3. 0kg / m ² shared porosity 5% or less (occupation ratio of the sum of overlapping portions of pore-like gaps generated in stacked fabrics) and air permeability (JIS L1096: Fragil method) 5-100 cc / cm ² / sec In the same way, warp triple woven fabric (texture, middle warp and back warp are organized on one set of weft), weft triple fabric (face warp, mid warp and back weave are organized on one set of warp) Triple fabric: a) Weaving 3 fabrics with the same loom, and connecting the lower fabric to the middle fabric with the yarn, and connecting the middle fabric to the upper fabric. ) From upper fabric to middle fabric, from middle fabric to lower fabric, c) From upper fabric to middle fabric, from lower fabric to middle fabric, d) Upper, middle and lower The thing which connected only the ear | edge part of three fabrics can be illustrated. If the air permeability is less than 5 cc / cm ² / sec, the adsorption and collection efficiency of odor molecules may be lowered and the sound absorbing effect may be deteriorated.

For double woven fabrics, we use fly shuttle looms, air jet looms, slewer looms, rapier looms, water jet looms, etc. to create a 2/1 oblique (twill) weave structure consisting of warps and wefts. The upper woven fabric and the lower woven fabric having a 2/1 oblique (twill) weave structure consisting of warps and wefts, the warps of the lower woven fabric float on the wefts of the upper fabric every predetermined number In this way, the double woven fabric is joined at the connection point so that the weft yarns of the lower fabric are floated on the warp yarns of the upper fabric every predetermined number. It is preferable to provide 8 to 50 connection points per square inch area. In the sound-absorbing membrane material using such a double woven fabric, the woven fabric has an upper fabric having a 2/1 oblique (twill) weave structure and a 2/1 oblique (weave) weave fabric. By forming a double woven fabric composed of a lower woven fabric having the structure of the upper fabric and the lower woven fabric, it is possible that the texture of the upper woven fabric and the lower woven fabric intersect and the voids of the respective woven fabrics do not completely overlap each other. Satisfying a shared porosity of 5% or less. This double woven fabric has a common porosity of 5% or less, and can satisfy an air permeability (JIS L1096: Frazier method) of 5 to 100 cc / cm ² / sec even when the apparent porosity is 0%. This is because the gap between the upper and lower fabrics functions as a vent (acts on gas exchange and deodorization for deodorizing effect) and connects the gap between the upper and lower fabrics in three dimensions. It depends on the action. Such a three-dimensional continuous ventilation portion effectively contributes to acoustic diffusion absorption. In addition, weaving intersections of warp and weft yarns fixed to each other by thermal adhesion are excellent in the form stability of the sheet-like woven fabric, especially those where heat fusion fixation is partially at the weaving intersections and thermal adhesion is slight Makes the sheet fabric more flexible. The fixing of the woven intersections by thermal adhesion may extend over the entire double woven fabric, or may be performed at equal intervals vertically or horizontally or at random partial woven intersections.

Similarly, in the triple woven fabric, each fabric's oblique line intersects with the adjacent fabric's oblique line because each fabric's oblique line intersects with the adjacent fabric's oblique line. Since they do not completely overlap each other, the shared porosity is 5% or less. Such a triple woven fabric has a common porosity of 5% or less, and can satisfy an air permeability (JIS L1096: Frazier method) of 5 to 100 cc / cm ² / sec even when the apparent porosity is 0%. This is because the gap between the interface between the upper fabric and the middle fabric and the interface between the middle fabric and the lower fabric functions as a vent (acts gas exchange and deodorization for deodorizing effect) This is due to the action of three-dimensionally connecting the voids of the woven fabric, middle woven fabric, and lower woven fabric. Such a three-dimensional continuous ventilation portion effectively contributes to gas exchange for deodorizing effect and acoustic diffusion absorption. In addition, the double woven fabric and the triple woven fabric structure are an upper woven fabric having an M / N oblique (twill) weave structure and a lower woven fabric having an M / N oblique (twill) weave structure. A double woven fabric (M = 2 to 5, an integer of N = 1) or (M = 1, an integer of N to 2 to 5), and an M / N oblique (twill) weave structure A triple woven fabric (M = 2 to 5 integers, N = 1) or (M = 1,) consisting of an upper woven fabric and a lower woven fabric, and a middle woven fabric having an M / N oblique (twill) weave structure N is an integer of 2 to 5. Similarly, even if the sound-absorbing film material of the present invention is a quadruple woven fabric, a five-fold woven fabric, etc., a corresponding deodorizing effect and sound absorbing effect are obtained.

Similarly, in the case of layered woven fabrics of plain fabric, imitation weave, five-sheet satin weave (2 jump 4/1 Auko, 3 jump 4/1 Auko, 2 jump 3/2 Auko, 3 jump 3/2 Auko) A fabric in which the tissue misalignment of the upper / lower or upper / middle / lower) is shifted by one complete structure vertically and horizontally so that the texture misalignment of the weaving structure does not overlap the same part. And Since the gap is shifted from the front, the common porosity is 5% or less. However, even if the apparent porosity is 0%, the air permeability (JIS L1096: Fragile method) can be satisfied from 5 to 100 cc / cm ² / sec. This is because the gap between one or two interfaces of the fabric (upper / lower, or upper / middle / lower) functions as a vent (acts gas exchange for deodorizing and sound absorption), This is due to the effect of three-dimensionally connecting the voids of the fabric. Such a three-dimensional continuous ventilation portion effectively contributes to gas exchange for deodorizing effect and acoustic diffusion absorption. Further, it is a triaxial woven fabric in which two or three woven fabrics using warp yarns and bias yarns on the left oblique upper and right oblique upper portions are overlapped, each having a void ratio of 10% or less and a mass of 0.8 to Triaxial plain fabric, triaxial basket fabric or triaxial mimetic fabric satisfying 3.0 kg / m ² , shared porosity of 5% or less and air permeability (JIS L1096: Frazier method) 5 to 100 cc / cm ² / sec Further, a woven fabric using warp yarns, weft yarns and left-upper / right-upward bias yarns is a four-axis woven fabric in which two or three layers overlap each other, and the woven fabric has a porosity of 10% or less in each part, A 4-axis flat woven fabric or a 4-axis basket woven fabric satisfying a mass of 0.8 to 3.0 kg / m ² , a shared porosity of 5% or less, and an air permeability (JIS L1096: Frazier method) of 5 to 100 cc / cm ² / sec. It may be a four-axis mimetic fabric.

  In the above-mentioned individual woven fabrics, the woven intersections of the yarns that are fixed to each other by thermal adhesion are excellent in the form stability of the sheet-shaped woven fabric, and those that are not melted and fixed at the woven intersections at all or have little thermal adhesion. The flexibility of the deodorant fabric is made more flexible. The fixing of the woven intersections by thermal adhesion may extend over the entire woven fabric, or may be performed at equal intervals vertically or horizontally, or at random partial woven intersections. Thermal adhesion is a means of applying heat above the softening temperature of the resin coating layer to melt and fuse the weaving intersection, for example, a hot air set at 150 to 300 ° C., a woven fabric whole surface nip by a hot roll at 150 to 230 ° C., or a partial nip, Examples include a full-textile press using a hot plate or a partial press.

  The construction of the deodorant fabric of the present invention is applied to a ceiling area constituting film material (film) installed on the ceiling of indoor stadiums, gymnasiums, indoor pools, event halls, public halls, ceremonial occasions, station buildings, airports, shopping malls, etc. Ceilings), ceiling accessories (aerial membranes), banners, banners, as well as construction of space partitions, wall hangings, rugs, aerial membranes in food factories, chemical factories, livestock facilities, fisheries facilities, garbage disposal facilities, etc. Arbitrary standard sheets with a width of 1 m to 3 m and lengths of 1 m to 50 m can be freely combined, and the fabric surface side is attached as an acoustic incident surface. Especially 1). One fabric is about 1m to 3m in width and about 1m to 5m in length.

In addition, a long woven fabric with a width of about 1m to 3m and a length of about 1m to 10m is a half of which the fabric is loosened by its own weight without applying tension, by fixing two sides in the width direction to the ceiling beam or aluminum pressing member. Can be used for design art ceilings that are suspended in a circular arc and represent a series of semi-circular arcs with multiple fabrics 3).
