Description
本発明は、デシカントロータの構造ならびに製造方法に関する。 The present invention relates to a structure of a desiccant rotor and a manufacturing method thereof.
高分子収着剤をはじめ各種吸湿剤を担持するデシカントロータの製造工程は、以下の行程を有する。吸湿剤を担持する一定幅のシートと、該シートをコルゲート加工した後に接合してダンボール構造体を製造し、その後、ダンボール構造体を筒状体（以下、内筒と記載する）の外周に所定外直径になるまで巻回し円盤状構造体を形成した後に、円盤状構造体を外筒に収めた後、接着行程等を経て一体化される。この製造工程の最終段階で、円盤状構造体の両端面部分に一定寸法深さまでエポキシ樹脂や液体ガラスなどを含浸させた後に固化し表面硬度を確保した上で表面が円滑な状態となるように成形される。また、デシカントロータの通風機能は、ダンボール構造体を巻回して形成されるハニカム状の通風孔にて確保される。 The manufacturing process of a desiccant rotor carrying various sorbents including a polymer sorbent has the following steps. A corrugated sheet is bonded to the sheet having a certain width carrying the moisture absorbent and then bonded to manufacture a corrugated cardboard structure. Thereafter, the corrugated cardboard structure is predetermined on the outer periphery of a cylindrical body (hereinafter referred to as an inner cylinder). After winding to an outer diameter to form a disk-like structure, the disk-like structure is housed in an outer cylinder and then integrated through an adhesion process or the like. At the final stage of this manufacturing process, both ends of the disc-shaped structure are impregnated with epoxy resin or liquid glass to a certain depth, and then solidified to ensure surface hardness and smooth surface. Molded. Further, the ventilation function of the desiccant rotor is ensured by the honeycomb-shaped ventilation holes formed by winding the cardboard structure.
家庭用の小型除湿器などに使用されるデシカントロータは、特段の真円度が要求されないため円盤状構造体を外筒内に固着した状態で完成するが、大容量の空気を調湿する大型のデシカントロータでは、シール性能を確保するために、デシカントロータの両端面の平滑度とロータ外筒の真円度が要求される。このため、回転軸を形成する内筒とロータ外筒は、複数枚の放射状平板スポークを溶接することで接続されている。その結果、放射状の平板スポークと内外筒から構成される扇形に円盤状構造体を分割して（丁度、放射状に切り分けられたバームクーヘンのような形で）嵌め込んだ後に、内筒、扇形に分割された円盤状構造体、外筒を接着することで一体化が行われている。 Desiccant rotors used in small household dehumidifiers are completed with a disc-like structure fixed inside the outer cylinder because no particular roundness is required, but large desiccant rotors that conditioned large volumes of air. In this desiccant rotor, smoothness of both end faces of the desiccant rotor and roundness of the rotor outer cylinder are required to ensure sealing performance. For this reason, the inner cylinder and rotor outer cylinder which form a rotating shaft are connected by welding a plurality of radial flat-plate spokes. As a result, the disk-shaped structure is divided into fan-shaped parts composed of radial flat-plate spokes and inner and outer cylinders (just like the shape of Baumkuchen cut out radially), and then divided into inner cylinders and fan-shaped parts. Integration is performed by bonding the disk-shaped structure and the outer cylinder.
このように、放射状の平板スポークと内外筒から構成される扇形部分に嵌め込まれた（分割された）円盤状構造体は枠と接着されているが、吸湿剤の吸放湿に伴う膨張、収縮が繰り返されるため、長期間の使用で積層されているダンボール構造体の接着劣化、放射状平板スポークや内外筒との接着劣化等のために、積層面の剥離や平板スポークや内外筒との部分的剥離、それらに伴う変形などの事故が報告されている。 In this way, the disk-like structure fitted (divided) into the fan-shaped portion composed of the radial flat-plate spokes and the inner and outer cylinders is bonded to the frame, but expands and contracts due to moisture absorption and desorption of the moisture absorbent. Is repeated for a long period of time, due to adhesion deterioration of corrugated cardboard structures that have been laminated over a long period of time, deterioration of adhesion to radial flat spokes or inner and outer cylinders, etc. Accidents such as peeling and associated deformation have been reported.
非特許文献１には、６０年以上前にスウェーデンの科学者Carl Munters によりデシカントロータが発明されて以来、その基本構造は現在も変わっていない旨が記されている。すなわち、デシカントロータの形状と強度は、内筒、外筒、ならびに両者を同心円状に結合する平板スポークにて担保されており、これら強度メンバーにて形成される扇状スペースに分割された円盤状構造体が嵌め込まれてデシカントロータが形成されている。
Non-Patent
これまではシリカゲルなどの鉱物系吸湿剤を、セラミック(粘土)と混練してシート状としてダンボール構造体を作成し、これを巻回して円盤状構造体とした後に焼成して固化成形する製造方法が一般的であった。この場合、焼成過程で割れや変形が生じるので、これらの欠陥部分を除去した後に、前述したように、内筒、外筒、ならびに両者を同心円状に結合する平板スポークにて形成される扇状スペースに合致するように円盤状構造体を分割して嵌め込む方法となる。この製造方法はセラミックを使用するための円盤状構造体重量を保持するためのロータ強度確保のためにも不可欠であった。 So far, a mineral hygroscopic agent such as silica gel is kneaded with ceramic (clay) to create a corrugated cardboard structure as a sheet, and this is wound into a disk-shaped structure and then fired and solidified and molded Was common. In this case, cracks and deformations occur during the firing process, and after removing these defective portions, as described above, the fan-shaped space formed by the inner cylinder, the outer cylinder, and the flat plate spokes concentrically connecting them. The disc-like structure is divided and fitted so as to match the above. This manufacturing method was also indispensable for ensuring the rotor strength for maintaining the weight of the disk-like structure for using ceramic.
最近は、高分子収着剤に代表される化学系吸湿剤を紙等のシートに担持させ、ダンボール構造体や円盤状構造体を製造しデシカントロータに用いることが一般化している。 Recently, it has become common to produce a corrugated cardboard structure or a disk-shaped structure by supporting a chemical moisture absorbent typified by a polymer sorbent on a sheet of paper or the like and use it in a desiccant rotor.
化学系吸湿剤を用いた円盤状構造体では焼成工程が不要で、割れや変形の発生要因は無く、かつ軽量となるが、内筒と外筒を同心状態とするために内筒と外筒を平板スポークにて結合する手法が採用されている。その結果、化学系吸湿剤を使用するデシカントロータにおいてもダンボール構造体を巻回して形成される円盤状構造体を分割して扇状の枠に嵌め込む作業が行われている。 A disc-shaped structure using a chemical-based moisture absorbent does not require a firing process, does not cause cracking or deformation, and is lightweight, but the inner and outer cylinders are concentric to keep the inner and outer cylinders concentric. A method of joining the plates with flat spokes is adopted. As a result, even in a desiccant rotor using a chemical moisture absorbent, an operation of dividing a disk-shaped structure formed by winding a corrugated cardboard structure and fitting it into a fan-shaped frame is performed.
扇状に分割された化学系吸湿剤を用いた円盤状構造体では、水分の吸放湿に伴う扇状構造体の膨張、収縮にともなうダンボール構造体間の剥離や、内筒、外筒、あるいは平板スポークとの接着面の剥離に伴う隙間発生や、分割された円盤状構造体の変形に伴うシール破損などの事故が発生している。 In a disk-shaped structure using a chemical-type moisture absorbent divided into fan-shaped structures, peeling between cardboard structures as the fan-shaped structure expands or contracts due to moisture absorption and desorption, inner cylinder, outer cylinder, or flat plate Accidents such as generation of gaps due to separation of the adhesion surface with the spokes and damage to the seals due to deformation of the divided disk-like structures have occurred.
本発明の主たる目的は、化学系吸湿剤を用いるデシカントロータの製造方法を改善し、かつ長期間の使用においても円盤状構造体の剥離や、変形等を防止できるデシカントロータを提供することである。 The main object of the present invention is to provide a desiccant rotor that can improve the method for producing a desiccant rotor using a chemical moisture absorbent and can prevent the disc-like structure from being peeled off or deformed even when used for a long period of time. .
本発明によれば、内筒上に巻回されるダンボール状構造体が所定直径となった後に、その外周にクッション性を有するスポンジシート構造体を所定寸法となるまで巻回し、これを外筒に密接した状態で嵌め込み固着した後に、内筒、外筒、スポンジシート構造体を有する円盤状構造体を直径５ｍｍ以下のスポークにて一体化したデシカントロータが提供される。前記スポークは内筒と外筒間に複数本設置され、その張力により内外筒を同心円状に成形している。
According to the present invention, after the corrugated cardboard-like structure wound on the inner cylinder has a predetermined diameter, a sponge sheet structure having cushioning properties is wound on the outer periphery thereof until the predetermined dimension is obtained, and this is wound on the outer cylinder. A desiccant rotor is provided in which a disc-like structure having an inner cylinder, an outer cylinder, and a sponge sheet structure is integrated with spokes having a diameter of 5 mm or less after being fitted and fixed in close contact with each other. A plurality of the spokes are installed between the inner cylinder and the outer cylinder, and the inner and outer cylinders are formed concentrically by the tension.
ダンボール構造体は巻回時に相互接着作用が発生し、その上、円盤状構造体およびスポンジシート構造体は巻回積層された一体形状を保つため、ダンボール構造体には常に巻回力が作用する。また、従来のように円盤状構造体を扇形状に分割する必要がないので、吸放湿に伴う円盤状構造体の膨張、収縮などの変形においても、ダンボール構造体は巻回力にて固定化される構成である。スポークと円盤状構造体の間は半径方向に滑りを許容する構造としている。 Since the corrugated cardboard structure has a mutual adhesive action during winding, the disk-like structure and the sponge sheet structure maintain an integrated shape in which the corrugated cardboard structure is wound and laminated, so that a winding force always acts on the cardboard structure. In addition, it is not necessary to divide the disk-like structure into a fan shape as in the past, so the corrugated cardboard structure is fixed by the winding force even when the disk-like structure is expanded or contracted due to moisture absorption and desorption. It is the composition which is done. Between the spoke and the disk-shaped structure, a structure that allows sliding in the radial direction is adopted.
本発明によるデシカントロータは、前述のように内筒上にダンボール構造体を巻回することで一体型の円盤状構造体が形成され、その後、最外周にクッション材を設置した後に外筒を装着し、最終的に外筒、クッション材、円盤状構造体、内筒の半径方向に複数の放射状の貫通孔を設置し、該貫通孔にスポークを差し込んだ後に、内筒、外筒とスポークを結合させているので、外筒と内筒の軸心を一致させ、かつ外筒の真円形状も正確に調整しつつデシカントロータの一体化が完成している。 As described above, the desiccant rotor according to the present invention forms an integrated disk-like structure by winding a corrugated cardboard structure on the inner cylinder, and then installs the outer cylinder after installing a cushion material on the outermost periphery. Finally, after installing a plurality of radial through holes in the radial direction of the outer cylinder, cushion material, disk-shaped structure, and inner cylinder, and inserting the spokes into the through holes, the inner cylinder, the outer cylinder and the spokes Since they are coupled, the desiccant rotor has been integrated while aligning the axial centers of the outer cylinder and the inner cylinder and accurately adjusting the perfect circle shape of the outer cylinder.
その結果、円盤状構造体を分割する必要が無く、水蒸気の吸放湿に伴う体積の増加・減少を繰り返しても、常にダンボール構造体に巻回力が作用するので、従来品（扇状に分割された円盤状構造体）に見られたダンボール構造体間の剥離や、剥離に伴う変形、あるいは内筒、外筒、あるいは平板スポークと扇状に分割された円盤状構造体の剥離に伴う変形、離脱、隙間発生などが抑制される。 As a result, there is no need to divide the disk-like structure, and even if the volume increases and decreases due to moisture absorption and desorption of water vapor, the winding force always acts on the cardboard structure. Deformation between the corrugated cardboard structures seen in the disk-like structure), deformation associated with delamination, or deformation or separation associated with delamination of the inner cylinder, outer cylinder, or flat-plate spoke and the disk-like structure. Generation of gaps is suppressed.
また、本発明によるデシカントロータでは、直径が５ｍｍ以下のスポークを放射状に設置し、内筒および外筒とスポークをネジ構造により結合したので、外筒と内筒の間には常に引っ張り力が作用し、外筒の真円度ならびに内外筒の同軸性などの調整が可能となったほか、スポークと円盤状構造体、あるいはスポンジシート構造体の間は滑りが許容されるため、吸放湿にともなう円盤状構造体の変形も単純にスポンジシート構造体が吸収する構成とすることが可能となっている。 Further, in the desiccant rotor according to the present invention, since the spokes having a diameter of 5 mm or less are radially installed and the inner cylinder, the outer cylinder and the spoke are coupled by a screw structure, a tensile force always acts between the outer cylinder and the inner cylinder. In addition, it is possible to adjust the roundness of the outer cylinder and the coaxiality of the inner and outer cylinders, and the sliding between the spokes and the disc-like structure or sponge sheet structure is allowed. It is possible to adopt a configuration in which the deformation of the accompanying disk-like structure is simply absorbed by the sponge sheet structure.
また、本発明によるデシカントロータでは、直径５ｍｍ以下のスポークを、軸方向の同一平面内で半径方向に複数本設置するので、通気孔を閉塞する作用を最小限とすることが可能である。 Further, in the desiccant rotor according to the present invention, since a plurality of spokes having a diameter of 5 mm or less are installed in the radial direction within the same plane in the axial direction, it is possible to minimize the action of closing the vent hole.
また、本発明によるデシカントロータでは、ダンボール構造体を所定の直径寸法まで巻回した後に外周部分をスポンジシートなどの弾力性のある材料でテーピングした後に外周部に接着剤を塗布してから外筒を嵌め合わせているので、円盤状構造体の形状が安定し、かつ外筒との接着性ならびに円盤状構造体の膨張、収縮に対する応力緩和が可能となっている。 Further, in the desiccant rotor according to the present invention, after winding the corrugated cardboard structure to a predetermined diameter, taping the outer peripheral portion with an elastic material such as a sponge sheet, and then applying an adhesive to the outer peripheral portion, then the outer cylinder Therefore, the shape of the disk-like structure is stable, and the adhesiveness to the outer cylinder and the stress relaxation for the expansion and contraction of the disk-like structure are possible.
また、本発明によるデシカントロータでは、内筒、円盤状構造体、その外周部分のスポンジシート、さらに外筒を組み合わせて固着した後に、外筒側から直径５ｍｍ程度の細孔を内筒側（軸心）へ向けて直角に穿孔した後に、当該細孔に外筒側から直径５ｍｍ以下のスポークを差し込み、内筒の内周側にて該スポークの先端をネジ固定し、その後、外筒側の外周にても同様に該スポークの先端と外筒をネジ固定したので、円盤状構造体を分割することなく内筒と外筒を同心状に固着することが可能となった。 In the desiccant rotor according to the present invention, the inner cylinder, the disk-shaped structure, the sponge sheet on the outer peripheral portion thereof, and the outer cylinder are combined and fixed, and then a pore having a diameter of about 5 mm from the outer cylinder side is formed on the inner cylinder side (shaft After drilling at a right angle toward the center), a spoke having a diameter of 5 mm or less is inserted into the pore from the outer cylinder side, and the tip of the spoke is screwed to the inner circumference side of the inner cylinder. Similarly, since the tip of the spoke and the outer cylinder are screwed to the outer periphery, the inner cylinder and the outer cylinder can be fixed concentrically without dividing the disk-like structure.
また、本発明によるデシカントロータでは、内筒と外筒の間を複数本のスポークにて連結しているので、該スポークの張力を固定ネジの調整にて実施できるため、外筒の真円度を維持した上で、内筒と外筒を同心円状で強固に結合することが可能となった。 In the desiccant rotor according to the present invention, since the inner cylinder and the outer cylinder are connected by a plurality of spokes, the tension of the spokes can be adjusted by adjusting the fixing screw. In addition, the inner cylinder and the outer cylinder can be concentrically and firmly joined together.
また、本発明によるデシカントロータでは、内筒と外筒を固定する複数のスポークを、軸方向に所定間隔で複数個所に設置したので、ほぼ同一の通風孔を複数本のスポークが横切る構成となるため、通風機能の消失を最小化するスポーク設置が可能となった。 In the desiccant rotor according to the present invention, since the plurality of spokes for fixing the inner cylinder and the outer cylinder are installed at a plurality of positions at predetermined intervals in the axial direction, the plurality of spokes traverse substantially the same ventilation hole. Therefore, it was possible to install spokes that minimize the loss of ventilation function.
このように、本発明によるデシカントロータでは、従来ロータで不可欠であった内筒と外筒を接続する厚さ数ｍｍ程度の平板スポークと、これによる円盤状構造体の分割が不要となった。すなわち、巻回された状態の円盤状構造体を内筒と外筒の間に固着し、多数の半径方向のスポークにて、内筒、円盤状構造体、外筒を一体的に結合させたので、扇型に分割された円盤状構造体に見られる層間の剥離が発生しにくい構造になると共に、デシカントロータの製造工程が簡略され、コスト低下とデシカントロータの長期にわたる機能維持が可能となった。 As described above, in the desiccant rotor according to the present invention, the flat spokes having a thickness of about several millimeters connecting the inner cylinder and the outer cylinder, which have been indispensable in the conventional rotor, and the division of the disk-like structure by this are no longer necessary. That is, the wound disk-shaped structure is fixed between the inner cylinder and the outer cylinder, and the inner cylinder, the disk-shaped structure, and the outer cylinder are integrally coupled with a large number of radial spokes. Therefore, it becomes a structure in which the separation between layers seen in the disk-shaped structure divided into fan-shaped structures is difficult to occur, the manufacturing process of the desiccant rotor is simplified, and the cost can be reduced and the function of the desiccant rotor can be maintained over a long period of time. It was.
また、本発明によるデシカントロータでは、ダンボール構造体を巻回する際に、ダンボール構造体が持つ相互接着機能が発揮され、かつ巻回による張力が長期間にわたり開放されることなくデシカントロータが形成される。加えて、ダンボール構造体の巻回が機械的に行われるため、円盤状構造体両端の通風面の表面を凹凸なく均一に成形することが可能となる。また、水蒸気の吸脱着に伴うデシカントロータの半径方向の膨張、収縮による変形に対しても、円盤状構造体の最外周に設置したスポンジシート構造体が変形を吸収し、かつ、円盤状構造体とスポークとの間も摺動が許されるので、長期間の使用においても変形や接着面の破壊が発生しない。 In the desiccant rotor according to the present invention, when the cardboard structure is wound, the mutual adhesion function of the cardboard structure is exhibited, and the desiccant rotor is formed without releasing the tension caused by winding over a long period of time. The In addition, since the corrugated cardboard structure is mechanically wound, the surfaces of the ventilation surfaces at both ends of the disk-shaped structure can be uniformly formed without unevenness. In addition, the sponge sheet structure installed on the outermost periphery of the disc-like structure absorbs the deformation against the deformation caused by the expansion and contraction in the radial direction of the desiccant rotor accompanying the adsorption / desorption of water vapor, and the disc-like structure Since sliding is allowed between the spoke and the spoke, deformation and destruction of the adhesive surface do not occur even after long-term use.
以下、本発明の実施の形態について図面を参照しながら詳述する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
図１に示すように、デシカントロータ（１０）は、内筒（筒状体）（１）の外側に、ダンボール構造体（２）が巻回されて円盤状構造体（３）を形成しており、その最外周部にはスポンジシート構造体（４）が巻回されており、外筒（５）に密着した状態で嵌合されている。その上で、外筒（５）の外側から内筒（１）へ向けて半径方向に細孔加工が施された後、図２に示すように、外筒（５）側から貫通孔（７）に沿ってスポーク（６）が内筒（１）へ向けて差し込まれる。その後、スポーク（６）の両端部に加工されているネジ部（６−１）にワッシャ（８）、ナット（９）が設置される。 As shown in FIG. 1, the desiccant rotor (10) has a disk-like structure (3) formed by winding a corrugated cardboard structure (2) on the outside of an inner cylinder (tubular body) (1). The sponge sheet structure (4) is wound around the outermost peripheral portion and is fitted in close contact with the outer cylinder (5). On top of that, after the fine hole processing is performed in the radial direction from the outside of the outer cylinder (5) into the inner cylinder (1), as shown in FIG. 2, the outer tube (5) through the side hole (7 ), The spoke (6) is inserted toward the inner cylinder (1). Then, a washer (8) and a nut (9) are installed in the thread part (6-1) processed at the both ends of the spoke (6).
このようにして、複数本のスポーク（６）が内筒（１）、円盤状構造体（３）、スポンジシート構造体（４）、外筒（５）に放射状に設置された後、各スポーク（６）の両端部に設置されたナット（９）の締め付け力を調整することで、外筒（５）と内筒（１）の軸心を一致させ、かつ外筒（５）の真円度が形成される。 In this way, after the plurality of spokes (6) are radially disposed on the inner cylinder (1), the disk-like structure (3), the sponge sheet structure (4), and the outer cylinder (5), each spoke By adjusting the tightening force of the nuts (9) installed at both ends of (6), the axial centers of the outer cylinder (5) and the inner cylinder (1) are matched, and the perfect circle of the outer cylinder (5) Degrees are formed.
また、実施例１では、デシカントロータ（１０）において、内筒（１）の軸方向長さは円盤状構造体（３）あるいは円盤状構造体（３）と一体的に形成されているスポンジシート構造体（４）の軸方向長さより長く、かつ、円盤状構造体（３）の軸方向長さは、外筒（５）の軸方向長さよりも長いので、一体化されたデシカントロータ（１０）は、その両端面部において、円盤状構造体（３）あるいは円盤状構造体（３）と一体的に形成されているスポンジシート構造体（４）が外筒（５）より、所定長さだけ露出することとなる。その結果、デシカントロータの製造工程で不可欠な円盤状構造体（３）あるいは円盤状構造体（３）と一体的に形成されているスポンジシート構造体（４）の端面をエポキシ樹脂や液体ガラスなどの含浸による固化と、その後の表面の円滑加工を施した段階で、外筒（５）と同一平面に仕上げることが可能となっている。 In the first embodiment, in the desiccant rotor (10), the axial length of the inner cylinder (1) is a disc-like structure (3) or a sponge sheet formed integrally with the disc-like structure (3). Since the axial length of the structure (4) is longer and the axial length of the disc-shaped structure (3) is longer than the axial length of the outer cylinder (5), the integrated desiccant rotor (10 ), A disc-like structure (3) or a sponge sheet structure (4) formed integrally with the disc-like structure (3) at both end portions thereof is a predetermined length from the outer cylinder (5). It will be exposed. As a result, the end surface of the sponge sheet structure (4) formed integrally with the disc-like structure (3) or the disc-like structure (3), which is indispensable in the manufacturing process of the desiccant rotor, is bonded to an epoxy resin or liquid glass. It is possible to finish on the same plane as the outer cylinder (5) at the stage of solidification by impregnation of the resin and subsequent smooth processing of the surface.
また、実施例１では、図２に示すように内筒（１）、円盤状構造体（３）、スポンジシート構造体（４）、外筒（５）を結合する複数本のスポーク（６）を、デシカントロータ中心軸方向に直角な複数の放射同一面内において、それぞれの放射同一面に１本あるいは複数本設置する構造としたので、特に多数のスポーク（６）を設置する大型のデシカントロータにおいても、スポーク（６）による通風面積の減少を最小限とすることが可能となっている。 Moreover, in Example 1, as shown in FIG. 2, a plurality of spokes (6) connecting the inner cylinder (1), the disk-like structure (3), the sponge sheet structure (4), and the outer cylinder (5). Has a structure in which one or a plurality of spokes are installed on the same radiation plane in a plurality of radiation coplanar surfaces perpendicular to the central axis direction of the desiccant rotor. In particular, a large desiccant rotor in which a large number of spokes (6) are installed. In FIG. 5, it is possible to minimize the reduction of the ventilation area due to the spokes (6).
このように、本発明によるデシカントロータの実施例１では、吸湿剤として高分子収着剤などの化学系吸湿剤を用い、これを紙やガラス繊維シートなどに担持したシートをダンボール状に加工したダンボール構造体を製造し、これを巻回して図２に示すような円盤状構造体を形成しているので、通過空気との水蒸気吸放湿に伴い、円盤状構造体の体積変化が発生しても、巻回された構造であるために層間の剥離が防止される。 Thus, in Example 1 of the desiccant rotor according to the present invention, a chemical moisture absorbent such as a polymer sorbent was used as the moisture absorbent, and a sheet carrying the same on a paper or a glass fiber sheet was processed into a cardboard shape. Since the corrugated cardboard structure is manufactured and wound to form a disk-shaped structure as shown in FIG. 2, the volume change of the disk-shaped structure occurs due to moisture absorption and desorption with the passing air. However, since it is a wound structure, peeling between layers is prevented.
