Description
本発明は、消臭作用等の機能性シート及び機能性部材に関する。 The present invention relates to a functional sheet such as a deodorizing action and a functional member.
近年、汚染物質の排出、生活空間の室内や車内の気密化などにより、生活空間は著しく汚染され、悪臭、汚染粒子、微生物などに悩まされている。これらの悪臭には、主に尿や汗などのアンモニア臭、腐った食品などのトリメチルアミン臭、硫化水素臭、メチルメルカプタン臭などである。これらを消臭する繊維の例として、特開２００２−３９９１８７号公報や特開２００４−２９２９５６号公報に記載されたものがある。
特開平９−７５６３４号公報には、消臭あるいは殺菌作用のある繊維をプラスチック製筒コアにセットし、殺菌及び消臭を行う殺菌、消臭フィルターが記載されている。この殺菌、消臭フィルターは、アンモニア吸着性繊維と高い殺菌性を有するアクリル系繊維とを熱融着繊維により熱接着して得られる不織布を、プラスチック製筒コアに沿って均一に巻き、フィルターエレメントにして固定し、これを注水口、排水口を有するプラスチック製外筒内に装着して、水用殺菌、消臭フィルターとしている。In recent years, the living space has been remarkably polluted due to the discharge of pollutants, the airtightness of the interior of the living space and the interior of the vehicle, and has been plagued by bad odors, contaminated particles, microorganisms and the like. These malodors mainly include ammonia odor such as urine and sweat, trimethylamine odor such as rotten food, hydrogen sulfide odor and methyl mercaptan odor. Examples of fibers that deodorize these include those described in Japanese Patent Application Laid-Open Nos. 2002-399187 and 2004-292956.
Japanese Laid-Open Patent Publication No. 9-75634 describes a sterilization and deodorization filter that performs sterilization and deodorization by setting a fiber having a deodorizing or sterilizing action on a plastic cylinder core. This sterilizing and deodorizing filter is obtained by uniformly winding a nonwoven fabric obtained by heat-bonding ammonia-adsorbing fibers and highly sterilizing acrylic fibers with heat-bonding fibers along a plastic cylinder core. This is fixed in a plastic outer cylinder having a water inlet and a water outlet, and is used as a water sterilization and deodorant filter.
本発明は高い消臭作用等の効果を長期間発揮できかつ機械的に安定した機能性シートを提供することを目的とする。
また、本発明は高い消臭作用等の効果を長時間発揮できかつ機械的に安定した機能性シートをより通気性の良い状態で使用することができる二層機能性シートを提供することを目的とする。
そして、本発明は高い消臭作用等の効果を長時間発揮できかつ機械的に安定した機能性シートを用いた機能性部材を提供することを目的とする。
本発明者は、高い消臭作用等の効果を長期間発揮させるためには、太い繊維を使用し、単位長さ当たりの消臭等の量を多くする必要があることに思い至った。また、多くの臭いを消臭するためには消臭作用の異なる複数種類の消臭繊維を使用する必要があり、複数種類の太い繊維を均一に混合するためには適当な長さの短繊維とする必要もあることに思い至った。しかし、複数の太い繊維を繊維、機械的に安定した機能性シートを提供すべく研究を重ね、本発明を完成した。
本発明の機能性シートは、熱融着繊維が互いに融着して形成された不織布状のマトリックスと、該マトリックス内に保持された該熱融着繊維より太い機能性紡績片と、からなることを特徴とする。
本発明の機能性シートは、熱融着繊維が熱融着により互いに融着し、融着で形成されるマトリックス内に殺菌性、抗菌性、消臭性を有する機能性紡績片が保持される。機能性紡績片は、殺菌性、抗菌性、消臭性を有する繊維を紡績して紡績糸とし、切断された紡績糸片である。
本発明の機能性シートで用いられる機能性紡績片は、繊維を紡績しているので繊維の状態よりも繊度が太く、熱融着繊維に対して所定質量比で混合すると、紡績片の本数を少なくすることができ、通気性を高くすることができる。更に、熱融着繊維に接触する表面積が、細い繊維の状態よりも広いので、１本の紡績片あたりの熱融着繊維の数が多くなり、脱落しにくい。
更に、機能性紡績片は、紡績糸を切断した紡績糸片であるため、長尺状で使用したときよりも長さを短い状態としているので、紡績片同士が絡みにくい。よって、塊になりにくく、マトリックスに均一に分布した状態で不織布状の機能性シートを作成することができる。
本発明の二層機能性シートは、熱融着繊維が互いに融着して形成された不織布状のマトリックスと該マトリックス内に保持された該熱融着繊維より太い機能性紡績片とからなる平板状の平板状シートと該平板状シートの一面に別の該平板状シートを波板状に折り曲げた波板状シートを重ね互いに対向して当接する該波板状シートの頂面部と該平板状シートの該一面とを熱融着して一体化したことを特徴とする。
本発明の二層機能性シートは、殺菌性、抗菌性、消臭性を有する機能性紡績片が熱融着により不織布状のマトリックスに保持されている機能性シートを、平板状と波板状の２枚を用いて、２枚を重ねて構成されている。平板状シートの一面に波板状に折り曲げた波板状シートの頂面部が熱融着により設着されて一体化している。波板状シートは頂面部が滑らかな円弧状でも鋭角状でも良く、平板状シートと波板状シートとで波筋方向の両端が開口した貫通孔が形成される。この二層機能性シートでは、平板状シートと波板状シートとで形成される波筋方向の一端開口から他端開口へと貫通孔が形成されるため、通気性の良い機能性シートとして使用することができる。つまり、平板状シートだけを積層するものに比べ、貫通孔が形成されている二層機能性シートの通気性が高いため、機能性シートの枚数に応じた殺菌、抗菌、消臭効果を十分に発揮することができる。
本発明の機能性部材は、吸入口と排出口とを有するケースと、該ケース内に保持され該吸入口側に一端開口を有し該排出口側に他端開口を有する多数の貫通孔を持つ機能性ハニカムと、を有する機能性部材であって、前記機能性ハニカムの前記貫通孔を区画する隔壁は、熱融着繊維が互いに融着して形成された不織布状のマトリックスと該マトリックス内に保持された該熱融着繊維より太い機能性紡績片とからなる機能性シートで構成されていることを特徴とする。
本発明の機能性部材は、殺菌性、抗菌性、消臭性を有する機能性紡績片が熱融着により不織布状のマトリックスに保持されている機能性シートを用いて、貫通孔を持つ機能性ハニカムが形成されており、この機能性ハニカムがケースに保持されている。機能性ハニカムは、一端開口から他端開口まで貫通した貫通孔が形成されるように機能性シートで構成されており、ケースの吸入口から導入された空気が排出口へと導出されるように、消臭ハニカムの開口端を考慮してケース内に保持される。この機能性部材は、貫通孔を持つため、機能性ハニカムの通気性が良く、貫通孔の通気性を考慮してケース内に保持するため、機能性シートをケースに使用した量に応じて殺菌、抗菌、消臭効果を十分に発揮することができる。
本発明の機能性シートで用いられる熱融着繊維は、熱融着温度で溶解しない芯部と該芯部の表面に保持された該熱融着温度で溶解する熱可塑性樹脂からなる表皮材とで構成されていることが好ましい。熱融着温度で溶解しない芯部が交差し、芯部の表面に保持された表皮材により交差した芯部同士が交差部分で熱融着され、マトリックスを形成することができる。
本発明の機能性シートで用いられる熱融着繊維は、基材となる第１熱融着繊維と、該第１熱融着繊維より太い第２熱融着繊維とからなることが好ましい。熱融着繊維として、基材となる第１熱融着繊維よりも繊度が太い第２熱融着繊維を混合すると、全体の質量に対しての本数を減らすことができ、通気性の良好な不織布とすることができる。また、一種類の熱融着繊維だけでなく、第２熱融着繊維のように太い熱融着繊維を適度に混合することで、マトリックスを強固なものとすることができ、繊維的に安定した機能性シートとすることができる。
本発明の機能性シートで用いられる熱融着繊維は、３デニール以上１００デニール以下であり、機能性紡績片は熱融着繊維の直径の５倍以上２５０倍以下の直径を持つことが好ましい。より好ましくは、機能性紡績片は熱融着繊維の直径の２０倍以上１００倍以下である。
本発明の機能性シートで用いられる熱融着繊維は、殺菌、抗菌、消臭作用のある機能性紡績片を保持することが必要であるため、機能性紡績片が脱落することなく熱融着させる直径が良い。熱融着繊維の直径が大きいと紡績片との接触面積が広くなり、紡績片の消臭作用等の効果を阻害することとなり、また直径が小さすぎると熱融着するのに十分ではなくなり紡績片が保持できなくなる。そこで、機能性紡績片は熱融着繊維の直径の５倍以上２５０倍以下が望ましく、より望ましくは２０倍以上１００倍以下である。
本発明の機能性シートで用いられる熱融着繊維と機能性紡績片との質量比は、合わせて１００とした場合、熱融着繊維が１０以上９０以下であることが好ましい。より好ましくは、熱融着繊維が３０以上７０以下である。
本発明の機能性シートは、熱融着繊維と機能性紡績片とのどちらかだけでは、機能性シートを構成することができない。また、殺菌性、抗菌性、消臭性を高めるため機能性紡績片が多すぎれば熱融着で紡績片が保持されにくく機能性紡績片が少なすぎれば消臭作用等の効果が低くなる。そこで、熱融着繊維と機能性紡績片との質量比は、合わせて１００とした場合、熱融着繊維が１０以上９０以下であることが望ましく、より望ましくは熱融着繊維が３０以上７０以下である。
本発明の機能性シートで用いられる熱融着繊維は、３５ｇ／ｍ２以上１２０ｇ／ｍ２以下であることが好ましく、よし好ましくは５５ｇ／ｍ２以上１００ｇ／ｍ２以下である。
本発明の機能性シートでは、１ｍ２当たりの熱融着繊維の量が少なくてもマトリックスを形成することでしっかりとした不織布状のシートを形成することができるため、軽くて丈夫である。
本発明の機能性シートで用いられる機能性紡績片の長さは、１０ｍｍ以上２０ｍｍ以下であることが好ましい。この機能性紡績片の長さを１０ｍｍ未満とすれば、熱融着繊維と混合して開繊しても、短すぎて均一に分散できないだけでなく、ウェブの状態にしたときに熱融着繊維に絡まず脱落しやすい。また、機能性紡績片の長さを２０ｍｍより長くすると混合して開繊したときに開繊しにくいため、塊となりやすく、均一に分布させにくい。よって、機能性紡績片の長さを１０ｍｍ以上２０ｍｍ以下とすることで、熱融着繊維と混合して開繊したときに、均一に分布させることができ、熱融着繊維に適度に絡み付いた状態となるので、脱落しにくい安定した状態とすることができる。
本発明の機能性シートによれば、熱融着繊維に殺菌性、抗菌性、消臭性を有する機能性紡績片を混合して開繊したウェブを、熱融着した不織布としたことで開繊しても塊になりにくく、機能性紡績片を均一に分布させることができ、熱融着繊維に安定した状態で熱融着することができる。その上、第１熱融着繊維とそれより太い第２熱融着繊維とからなる熱融着繊維を用いることで、全体の質量に対しての本数が減り、通気性の良い不織布とすることができるため、部屋などに載置した状態で放置しておくだけで、機能性紡績片が有する消臭作用等の効果をいかんなく発揮することができる。また、熱融着繊維の量も少量とすることができるため、軽くて丈夫な機能性シートとすることができる。
機能性紡績片の長さを１０ｍｍ以上２０ｍｍ以下とすることで、紡績片がより均一に分布した不織布とすることができるので、地合を良好とすることができるだけでなく、毛羽だったりしていないので見栄えが良い。また、ウェブ状態で紡績片が脱落などしないので、紡績片の歩留まりがよい。
本発明の二層機能性シートによれば、平板状の平板状シートに波板状の波板状シートが重ねて熱融着されているため、波筋方向に貫通孔が形成されており、機能性シートを複数重ねて利用する場合、平板状シートを重ねるより通気性の確保された状態で殺菌、抗菌、消臭を効果的に行うことができる。
本発明の機能性部材によれば、吸入口と排出口とを有するケースに吸入口と排出口とに開口端を有する機能性ハニカムが保持されているため、吸入口から導入される空気の殺菌、消臭を機能性シートで行うことができ、浄化された空気が排出口からスムーズに排出することができる。An object of this invention is to provide the functional sheet which can exhibit effects, such as a high deodorizing effect | action, for a long period of time, and was stabilized mechanically.
Another object of the present invention is to provide a two-layer functional sheet that can exhibit an effect such as a high deodorizing action for a long time and can use a mechanically stable functional sheet in a more breathable state. And
And an object of this invention is to provide the functional member using the functional sheet | seat which can exhibit effects, such as a high deodorizing effect, for a long time, and is mechanically stable.
The present inventor has come up with the idea that it is necessary to use thick fibers and increase the amount of deodorization per unit length in order to exert a high deodorizing effect and the like for a long period of time. In addition, in order to deodorize many odors, it is necessary to use multiple types of deodorizing fibers with different deodorizing effects, and in order to uniformly mix multiple types of thick fibers, short fibers of appropriate length I came up with the need to However, research was repeated to provide a functional sheet in which a plurality of thick fibers are mechanically stable, and the present invention was completed.
The functional sheet of the present invention comprises a non-woven matrix formed by fusing heat-bonding fibers together, and a functionally spun piece thicker than the heat-bonding fibers held in the matrix. It is characterized by.
In the functional sheet of the present invention, the heat-spun fibers are fused to each other by heat-sealing, and a functional spinning piece having bactericidal, antibacterial, and deodorizing properties is held in a matrix formed by the fusing. . The functionally spun pieces are spun yarn pieces that are spun by spinning fibers having bactericidal properties, antibacterial properties, and deodorizing properties into spun yarns.
The functionally spun pieces used in the functional sheet of the present invention are spun fibers, so that the fineness is larger than the state of the fibers, and when mixed at a predetermined mass ratio with respect to the heat-fusible fibers, the number of spun pieces is reduced. The air permeability can be increased. Furthermore, since the surface area in contact with the heat-sealable fiber is wider than that of the thin fiber, the number of heat-sealable fibers per spun piece increases and it is difficult to fall off.
Furthermore, since the functional spun pieces are spun yarn pieces obtained by cutting spun yarns, the lengths are shorter than when they are used in a long shape, so that the spun pieces are not easily entangled with each other. Therefore, it is difficult to form a lump and a non-woven functional sheet can be produced in a state of being uniformly distributed in the matrix.
The two-layer functional sheet of the present invention is a flat plate comprising a non-woven matrix formed by fusing heat-bonding fibers to each other, and a functionally spun piece thicker than the heat-bonding fibers held in the matrix. A flat sheet and a corrugated sheet obtained by folding another flat sheet into a corrugated sheet on one surface of the flat sheet and the top surface portion of the corrugated sheet facing each other and the flat sheet The sheet is integrated with the one surface by heat fusion.
The two-layer functional sheet of the present invention includes a functional sheet in which a functional spun piece having bactericidal, antibacterial, and deodorizing properties is held in a non-woven matrix by heat fusion, flat and corrugated. The two sheets are used to overlap each other. A top surface portion of the corrugated sheet folded into a corrugated sheet is attached to and integrated with one surface of the flat sheet by heat fusion. The corrugated sheet may have an arcuate shape or an acute angle with a smooth top surface portion, and a flat hole and a corrugated sheet form a through-hole that is open at both ends in the wave line direction. In this two-layer functional sheet, a through-hole is formed from one end opening in the direction of the wavy line formed by the flat sheet and the corrugated sheet to the other end opening, so it is used as a functional sheet with good air permeability. can do. In other words, the two-layer functional sheet with through-holes has higher air permeability than the one in which only the flat sheet is laminated, so the sterilization, antibacterial and deodorizing effects according to the number of functional sheets are sufficient. It can be demonstrated.
The functional member of the present invention comprises a case having a suction port and a discharge port, and a plurality of through-holes held in the case and having one end opening on the suction port side and the other end opening on the discharge port side. And a functional member having a functional honeycomb, wherein the partition walls defining the through-holes of the functional honeycomb include a non-woven matrix formed by fusion of heat-bonding fibers to each other, and the matrix It is comprised by the functional sheet | seat which consists of a functional spinning piece thicker than this heat-fusion fiber hold | maintained in this.
The functional member of the present invention is a functional sheet having a through hole using a functional sheet in which a functional spun piece having bactericidal properties, antibacterial properties, and deodorizing properties is held in a non-woven matrix by heat fusion. A honeycomb is formed, and this functional honeycomb is held in the case. The functional honeycomb is composed of a functional sheet so that a through-hole penetrating from one end opening to the other end opening is formed, so that air introduced from the suction port of the case is led to the discharge port. In consideration of the opening end of the deodorant honeycomb, it is held in the case. Since this functional member has a through hole, the air permeability of the functional honeycomb is good, and it is held in the case in consideration of the air permeability of the through hole. , Antibacterial and deodorant effects can be fully exhibited.
The heat-sealable fiber used in the functional sheet of the present invention comprises a core part that does not melt at the heat-seal temperature and a skin material made of a thermoplastic resin that is held at the surface of the core part and that melts at the heat-seal temperature. It is preferable that it is comprised. The core portions that do not melt at the heat fusion temperature intersect, and the core portions intersected by the skin material held on the surface of the core portion are heat-sealed at the intersection portions, thereby forming a matrix.
The heat-sealing fiber used in the functional sheet of the present invention is preferably composed of a first heat-sealing fiber serving as a base material and a second heat-sealing fiber that is thicker than the first heat-sealing fiber. When the second heat-fusible fiber having a fineness larger than that of the first heat-fusible fiber serving as the base material is mixed as the heat-fusible fiber, the number of fibers with respect to the entire mass can be reduced, and the air permeability is good. It can be a non-woven fabric. In addition, not only one type of heat-bonding fiber but also a thick heat-bonding fiber such as the second heat-bonding fiber can be mixed properly to make the matrix strong and stable in terms of fiber. Functional sheet.
The heat-sealing fiber used in the functional sheet of the present invention has a diameter of 3 to 100 denier, and the functional spun piece preferably has a diameter of 5 to 250 times the diameter of the heat-sealing fiber. More preferably, the functionally spun piece has a diameter of 20 to 100 times the diameter of the heat-sealing fiber.
Since the heat-sealable fiber used in the functional sheet of the present invention is required to hold a functionally spun fiber having sterilization, antibacterial, and deodorizing functions, the heat-spun fiber is bonded without dropping off the functionally spun fiber Good diameter. If the diameter of the heat-sealable fiber is large, the contact area with the spun piece will be widened and the effect of deodorizing the spun piece will be hindered. If the diameter is too small, it will not be sufficient for heat-sealing. The piece cannot be held. Therefore, the functionally spun piece is preferably 5 to 250 times the diameter of the heat-sealing fiber, and more preferably 20 to 100 times.
When the mass ratio of the heat-sealable fiber and the functionally spun piece used in the functional sheet of the present invention is 100 in total, the heat-sealable fiber is preferably 10 or more and 90 or less. More preferably, the heat fusion fiber is 30 or more and 70 or less.
The functional sheet of the present invention cannot constitute a functional sheet only with either a heat-fusible fiber or a functionally spun piece. Further, if there are too many functional spun pieces in order to enhance bactericidal properties, antibacterial properties, and deodorizing properties, the spun pieces are difficult to be held by heat fusion, and if there are too few functional spun pieces, the effects such as deodorizing action are reduced. Therefore, when the mass ratio of the heat-sealable fiber and the functional spinning piece is 100 in total, it is desirable that the heat-sealable fiber is 10 or more and 90 or less, and more desirably the heat-sealable fiber is 30 or more and 70. It is as follows.
The heat-sealing fiber used in the functional sheet of the present invention is preferably 35 g / m 2 or more and 120 g / m 2 or less, more preferably 55 g / m 2 or more and 100 g / m 2 or less.
The functional sheet of the present invention is light and strong because a solid non-woven sheet can be formed by forming a matrix even if the amount of heat-sealing fibers per 1 m 2 is small.
The length of the functionally spun piece used in the functional sheet of the present invention is preferably 10 mm or more and 20 mm or less. If the length of the functionally spun piece is less than 10 mm, even if it is mixed with the heat-sealing fiber and opened, it is not too short to uniformly disperse. It is easy to fall off without getting entangled with the fiber. Also, if the length of the functionally spun piece is longer than 20 mm, it is difficult to open when mixed and opened, so that it tends to be a lump and difficult to distribute uniformly. Therefore, when the length of the functionally spun pieces is 10 mm or more and 20 mm or less, when the fiber is mixed and opened with the heat-fusible fiber, the functionally spun piece can be uniformly distributed and appropriately entangled with the heat-fused fiber Since it will be in a state, it can be set as the stable state which is hard to drop out.
According to the functional sheet of the present invention, a web obtained by mixing a heat-spun fiber with a functional spun fiber having bactericidal, antibacterial, and deodorizing properties and opening it into a heat-bonded nonwoven fabric is opened. Even if the fiber is fined, it is difficult to be agglomerated, the functionally spun pieces can be uniformly distributed, and the heat-bonded fibers can be heat-bonded in a stable state. In addition, by using a heat-bonding fiber composed of a first heat-bonding fiber and a thicker second heat-bonding fiber, the number of fibers with respect to the entire mass is reduced, and a non-woven fabric with good air permeability is obtained. Therefore, it is possible to exert the effects such as the deodorizing action of the functional spinning piece by simply leaving it in a state of being placed in a room or the like. Moreover, since the amount of heat-sealing fibers can be reduced, a light and durable functional sheet can be obtained.
By setting the length of the functionally spun pieces to 10 mm or more and 20 mm or less, the spun pieces can be made into a non-woven fabric with a more even distribution. It doesn't look good. Further, since the spun pieces do not fall off in the web state, the yield of the spun pieces is good.
According to the two-layer functional sheet of the present invention, the corrugated sheet is laminated and heat-sealed on the flat plate sheet, so that a through-hole is formed in the wave line direction. When a plurality of functional sheets are used in an overlapping manner, sterilization, antibacterial action, and deodorization can be effectively performed in a state where air permeability is ensured rather than stacking flat sheets.
According to the functional member of the present invention, the case having the suction port and the discharge port holds the functional honeycomb having the opening ends at the suction port and the discharge port, so that the air introduced from the suction port is sterilized. The deodorization can be performed with the functional sheet, and the purified air can be smoothly discharged from the discharge port.

以下、実施例を用いて本発明を具体的に説明する。 Hereinafter, the present invention will be specifically described with reference to examples.
本実施例１の消臭シート（機能性シート）の構成を示す模式図を第１図に示す。
本実施例１の消臭シート１は、熱融着繊維２が互いに融着して形成された不織布状のマトリックス３と、このマトリックス３に保持された紡績片（機能性紡績片）４とからなる。
熱融着繊維２は、サーマルボンド法で不織布を形成する際に用いられる鞘芯タイプの複合繊維であり、芯はポリプロピレン、芯の周りを覆うように鞘が変性されたポリエチレンで形成されている。芯としてポリプロピレンのものを使用しているが、ポリエステルのものも使用することができる。そして、基材となる第１熱融着繊維２１とそれより太い第２鞘熱融着繊維２２との２種類の熱融着繊維を混合させて熱融着繊維２としている。この２種類が含まれていれば、それよりも太い熱融着繊維や細い熱融着繊維を混合させて不織布とすることもできる。ただし、基材となる第１熱融着繊維２１よりも細い熱融着繊維を使用する場合は、消臭シートとしたときにマトリックスが弱くなるため、基材に対する混合比を抑制する必要がある。
熱融着繊維２は、１０デニール以上３０デニール以下であり、紡績片４の直径は、熱融着繊維２の直径の３０倍である。紡績片４は、公知の方法で消臭作用を付与した綿の紡績糸を長さ１５ｍｍに切断したものであり、酸性の臭いに対して消臭作用を有する紡績片４１と、アルカリ性の臭いに対して消臭作用を有する紡績片４２とを混合して使用している。紡績片４は、太すぎると熱融着繊維２と熱融着させたときに、紡績片４が浮き出てしまい手触りが悪い。また、細すぎると紡績片４の表面積が少ないので消臭作用が減少する。従って、この紡績片４の直径は、熱融着繊維２の直径の２０倍以上１００倍以下であることが望ましい。
以上のように構成される実施例１に係る消臭シート１の製造方法について説明する。
まず、熱融着繊維２を５０質量％準備する。また、酸性の臭いに対して消臭作用を有する紡積片４１を２５質量％と、アルカリ性の臭いに対して消臭作用を有する紡績片４２を２５質量％とを準備する。
次に、熱融着繊維２を開繊機へ投入して開繊する開繊工程を行う。この開繊工程では、比較的に隙間のある間隔で配置された針群で、熱融着繊維２を解きほぐしている。
次に、解きほぐされた熱融着繊維２に、酸性およびアルカリ性のそれぞれに消臭作用のある２種類の紡績片４１、４２を投入して混合する混合工程を行う。この混合工程では、開繊工程での開繊と同様に、比較的に隙間のある間隔で配置された針群で、熱融着繊維２と紡績片４とを開繊して攪拌することで、熱融着繊維２と紡績片４とを混合させる。本実施例１では紡績片４を１５ｍｍとしているが、１０ｍｍ以上２０ｍｍ以下とすることができる。紡績片４の長さを１０ｍｍ未満とすると、開繊しても短すぎて針群に引っかからないために、均一に分散させることができない。紡績片４の長さを２０ｍｍより長くすると、混合させるために開繊すると引き千切れたり、塊になったりする。従って、熱融着繊維２に紡績片４を適度に分布させた状態とするには、紡績片４の長さを１０ｍｍ以上２０ｍｍ以下とするのが望ましく、更に１５ｍｍとするのが望ましい。
次に、開繊工程および混合工程より間隔の狭まった針群で、更に細かく開繊を行う予備開繊工程を予備開繊機で行う。
そして、ウェブを形成するウェブ形成工程を行う。ウェブ形成工程では、予備開繊工程を終了した熱融着繊維２と紡績片４とを混合したものを重ねて目付を調節し、カード機に通過させて、更に細かく開繊して交絡させた状態にする。本実施例１では、紡績片４の長さを１５ｍｍとしているので、熱融着繊維２に交絡した状態とすることができる。例えば紡績片４の長さを１０ｍｍ未満とした場合では、熱融着繊維２に交絡せずに次工程に移送する際に脱落することがある。そうなると、脱落する紡績片４の量を勘案して紡績片４を熱融着繊維２に混入させる必要があるので歩留まりが低い。従って、紡績片４を１０ｍｍ以上とすることで、熱融着繊維２に交絡させ、紡績片４を安定した状態で分布させることができる。
最後に、ウェブを加熱されたローラー間を通過させて熱圧着を行う融着工程を行う。熱融着繊維２の芯であるポリプロピレンは融点が約１６０℃〜約１７０℃であり、鞘であるポリエチレンは融点が約１１０℃〜約１３０℃である。従ってローラーを１４０℃に加熱すると、芯のポリプロピレンの融点は１４０℃よりも高いため融解せずに繊維の状熊を維持し、鞘のポリエチレンが融解し、冷却後マトリックス３が形成される。よって、過熱されたローラーに挿入すると、芯は融解せずに繊維の状熊を維持したまま、鞘のポリエチレンが融解して交絡した紡績片４に付着する。そしてローラーを通過したウェブは鞘のポリエチレンが冷却して硬化することで、熱融着繊誰２が紡績片４に融着した状態となる。
このようにして得られた本実施例１に係る消臭シートを第２図に示す。第２図は、本実施例１に係る消臭シートの一例を示す図面代用写真である。
以上のように、消臭性を有する繊維を紡績して紡績糸とし、切断して紡績片とすることで、繊維よりも繊度が太い状態とすることができるので、紡績片を熱融着繊維に対して所定質量比で混合すると、繊維の状態よりも紡績片の本数を少なくすることができる。従って、塊になりにくく均一に分布させやすいので通気性が良く、消臭性を有する紡績糸の周囲全体が空気に触れるような状態にすることができ、この消臭シートを部屋などに載置した状態にしておくだけで、紡績片が有する消臭作用を発揮させることができる。例えば、室内や車内の壁紙に利用したりすることができる。FIG. 1 shows a schematic diagram showing the structure of the deodorant sheet (functional sheet) of Example 1. As shown in FIG.
The deodorant sheet 1 of Example 1 is composed of a non-woven matrix 3 formed by fusing heat-bonding fibers 2 to each other, and a spun piece (functional spun piece) 4 held by the matrix 3. Become.
The heat-fusible fiber 2 is a sheath-core type composite fiber used when forming a nonwoven fabric by the thermal bond method, and the core is formed of polypropylene and polyethylene whose sheath is modified so as to cover the periphery of the core. . Polypropylene is used as the core, but polyester can also be used. Then, two types of heat-sealing fibers, that is, the first heat-sealing fiber 21 serving as the base material and the second sheath heat-sealing fiber 22 that is thicker than that, are mixed to form the heat-sealing fiber 2. If these two types are included, it is possible to make a nonwoven fabric by mixing thicker heat-sealable fibers or thinner heat-sealable fibers. However, in the case of using a heat-fusible fiber that is thinner than the first heat-fusible fiber 21 serving as a base material, the matrix becomes weak when used as a deodorant sheet, so it is necessary to suppress the mixing ratio with respect to the base material. .
The heat-sealable fiber 2 is 10 denier or more and 30 denier or less, and the diameter of the spun piece 4 is 30 times the diameter of the heat-sealable fiber 2. The spun piece 4 is obtained by cutting a cotton spun yarn having a deodorizing effect by a known method into a length of 15 mm. On the other hand, the spun piece 42 having a deodorizing action is mixed and used. If the spun piece 4 is too thick, the spun piece 4 will be raised when it is heat-fused with the heat-fusible fiber 2, resulting in poor touch. On the other hand, if it is too thin, the surface area of the spun pieces 4 is small, so that the deodorizing action is reduced. Therefore, it is desirable that the diameter of the spun piece 4 is 20 times or more and 100 times or less than the diameter of the heat-fusible fiber 2.
The manufacturing method of the deodorizing sheet 1 which concerns on Example 1 comprised as mentioned above is demonstrated.
First, 50 mass% of the heat-fusible fiber 2 is prepared. Further, 25% by mass of the spun piece 41 having a deodorizing action with respect to an acidic odor and 25% by mass of the spun piece 42 having a deodorizing action with respect to an alkaline odor are prepared.
Next, a fiber-spreading process is performed in which the heat-fusible fiber 2 is put into a fiber spreader and opened. In this fiber opening step, the heat-fusible fiber 2 is unraveled with a group of needles arranged at a relatively gap.
Next, a mixing step is performed in which the two types of spun pieces 41 and 42 having a deodorizing effect on each of the acidic and alkaline are added to the unfused heat-fusible fiber 2 and mixed. In this mixing step, similarly to the opening in the opening step, the heat-sealed fiber 2 and the spun piece 4 are opened and stirred with a group of needles arranged at a relatively spaced gap. The heat fusion fiber 2 and the spun piece 4 are mixed. In the first embodiment, the spun piece 4 is 15 mm, but it can be 10 mm or more and 20 mm or less. If the length of the spun piece 4 is less than 10 mm, even if the fiber is opened, it is too short to be caught by the needle group, so that it cannot be uniformly dispersed. If the length of the spun piece 4 is longer than 20 mm, it will be torn or lump when opened for mixing. Therefore, in order to obtain a state in which the spun pieces 4 are appropriately distributed on the heat-fusible fiber 2, the length of the spun pieces 4 is preferably 10 mm or more and 20 mm or less, and more preferably 15 mm.
Next, a pre-opening process is performed by a pre-opening machine in which a finer opening is performed with a group of needles that are narrower than the opening process and the mixing process.
And the web formation process which forms a web is performed. In the web forming process, the heat-bonding fiber 2 and the spun piece 4 that have finished the pre-opening process are overlapped to adjust the basis weight, and are passed through a card machine, further finely opened and entangled. Put it in a state. In the present Example 1, since the length of the spun piece 4 is 15 mm, the spun fiber 2 can be in an entangled state. For example, when the length of the spun pieces 4 is less than 10 mm, the spun pieces 4 may fall off when transferred to the next step without being entangled with the heat-fusible fiber 2. In this case, the yield is low because it is necessary to mix the spun pieces 4 into the heat-fusible fiber 2 in consideration of the amount of spun pieces 4 that fall off. Therefore, by setting the spun pieces 4 to 10 mm or more, the spun pieces 4 can be entangled with the heat-fusible fiber 2 and distributed in a stable state.
Finally, a fusing process is performed in which the web is passed between heated rollers to perform thermocompression bonding. Polypropylene which is the core of the heat-fusible fiber 2 has a melting point of about 160 ° C. to about 170 ° C., and the polyethylene which is the sheath has a melting point of about 110 ° C. to about 130 ° C. Therefore, when the roller is heated to 140 ° C., the melting point of the core polypropylene is higher than 140 ° C., so that the fiber-like bear is maintained without melting, the sheath polyethylene is melted, and the matrix 3 is formed after cooling. Therefore, when inserted into the superheated roller, the core is not melted, and the sheath polyethylene is melted and adhered to the entangled spun pieces 4 while maintaining the shape of the fiber. And the web which passed the roller will be in the state which the heat sealing | fusion fiber 2 fused to the spinning piece 4 because the polyethylene of a sheath cooled and hardened | cured.
The deodorant sheet according to Example 1 obtained in this way is shown in FIG. FIG. 2 is a drawing-substituting photograph showing an example of the deodorizing sheet according to the first embodiment.
As described above, a fiber having deodorizing properties is spun into a spun yarn, and cut into a spun piece, so that the fineness can be made larger than that of the fiber. If the mixture is mixed at a predetermined mass ratio, the number of spun pieces can be reduced as compared with the fiber state. Therefore, since it is difficult to form a lump and is easily distributed uniformly, air permeability is good and the entire periphery of the spun yarn having deodorizing property can be brought into contact with air, and this deodorizing sheet is placed in a room or the like. It is possible to exert the deodorizing action of the spun piece only by maintaining the state. For example, it can be used for wallpaper in a room or in a car.
本実施例２の二層消臭シートの構成を示す斜視図を第３図に示す。
本実施例２の二層消臭シート５は、本実施例１の消臭シート１の平板状シート１１と波板状シート１２とからなる。二層消臭シート５は、平板状の平板状シート１１と平板状シート１１の一面１１１に平板状の消臭シート１を波板状に折り曲げた波板状シート１２を重ね互いに対向して当接する波板状シート１２の頂面部１２１と平板状シート１１の一面１１１とを熱融着して一体化して形成されている。波板状シート１２は、頂面部１２１が滑らかな円弧状を描いている。波板状シート１２は、頂面部１２１が滑らかな円弧状ではなく鋭角状でも良い。つまり、二層消臭シート５の波筋方向にそって平板状シート１１と波板状シート１２とで適度な空間が形成されていることが望ましい。The perspective view which shows the structure of the two-layer deodorizing sheet of the present Example 2 is shown in FIG.
The two-layer deodorizing sheet 5 of Example 2 is composed of a flat sheet 11 and a corrugated sheet 12 of the deodorizing sheet 1 of Example 1. The two-layer deodorant sheet 5 includes a flat plate sheet 11 and a corrugated sheet 12 obtained by folding the flat plate deodorant sheet 1 into a corrugated sheet on one surface 111 of the flat sheet 11 and facing each other. The top surface portion 121 of the corrugated sheet 12 in contact with the one surface 111 of the flat sheet 11 is integrally formed by heat fusion. The corrugated sheet 12 has a smooth arc shape at the top surface 121. In the corrugated sheet 12, the top surface portion 121 may have an acute angle shape instead of a smooth arc shape. That is, it is desirable that an appropriate space is formed by the flat sheet 11 and the corrugated sheet 12 along the wave line direction of the two-layer deodorizing sheet 5.
本実施例３の消臭部材（機能性部材）の構成を示す斜視図を第４図に示す。
本実施例３の消臭部材６は、ケース７とケース７内に保持される消臭ハニカム８とからなる。
ケース７は、おおむね直方体であり、一面に吸入口７１が開口しており、吸入口７１とは別の面に排出口７２が開口している。本実施例３のケース７では、排出口７２は、吸入口７１の開口している面と接している面において、吸入口７１の面と対向する面側寄りに開口している。
消臭ハニカム８は、本実施例１の消臭シート１で形成されている二層消臭シート５を積層してハニカム状を形成している。二層消臭シート５の波筋方向にそって貫通孔５０が形成されており、貫通孔５０の一端開口５１がケース７の吸入口７１に、貫通孔５０の他端開口５２がケース７の排出口７２側に位置するようにケース７の内部に保持されている。
消臭ハニカム８の一端開口５１からの図を第５図に示す。消臭ハニカム８は、複数枚の二層消臭シート５の頂面部１２１を一直線状に、波板状シートから平板状シート方向へと揃えて積層されている。
本実施例３の消臭部材６は、トイレの消臭や車内の空気清浄機などに設置することができる。消臭部材６の消臭ハニカム８は、実施例１の消臭シート１を用いられているため、殺菌性、抗菌性、消臭性に優れている。その上、実施例１の消臭シート１を実施例２の二層消臭シート５とし積層しているため、消臭シート１を複数枚重ねるよりも通気性が良いハニカム状となり、ケース７の吸入口７１から排出口７２へとスムーズな換気を行いながらの殺菌、抗菌、初秋を行うことができる。
以上、殺菌性、抗菌性、消臭性を有する紡績片を熱融着繊維に熱融着させてなる消臭シートを用いた消臭部材について好適な実施例について説明したが、本発明は上記実施例に限定されるものではない。例えば、消臭ハニカム８は第６図及び第７図に示すように、第５図とは異なる積層をすることが可能である。波板状消臭シート５の頂面部１２１をずらして積層されている図が第６図である。また、二層消臭シートの波筋方向と垂直で頂面部１２１から頂面部１２１へと向かう方向において、二層消臭シートを巻き回して積層状としてハニカムを形成しているのが第７図に示してある。このように、消臭部材６で用いられる消臭シート１からなる二層消臭シート５を積層してハニカム状の消臭ハニカム８を形成することができれば良い。また、消臭部材６のケース７の形状は、ケース７内部に消臭ハニカム８を保持する空間を有し、消臭ハニカム８の開口５１、５２に対向する吸入口７１と排出口７２とが形成されていれば良い。FIG. 4 shows a perspective view showing the structure of the deodorizing member (functional member) of the third embodiment.
The deodorizing member 6 according to the third embodiment includes a case 7 and a deodorizing honeycomb 8 held in the case 7.
The case 7 is generally a rectangular parallelepiped, and the suction port 71 is opened on one surface, and the discharge port 72 is opened on a surface different from the suction port 71. In the case 7 according to the third embodiment, the discharge port 72 opens toward the surface facing the surface of the suction port 71 on the surface in contact with the surface where the suction port 71 is opened.
The deodorizing honeycomb 8 is formed in a honeycomb shape by laminating the two-layer deodorizing sheet 5 formed of the deodorizing sheet 1 of the first embodiment. A through hole 50 is formed along the wave line direction of the two-layer deodorant sheet 5, one end opening 51 of the through hole 50 is formed in the suction port 71 of the case 7, and the other end opening 52 of the through hole 50 is formed in the case 7. It is held inside the case 7 so as to be positioned on the discharge port 72 side.
A view from the one end opening 51 of the deodorant honeycomb 8 is shown in FIG. The deodorizing honeycomb 8 is laminated with the top surface portions 121 of a plurality of double-layer deodorizing sheets 5 aligned in a straight line from the corrugated sheet to the flat sheet.
The deodorizing member 6 according to the third embodiment can be installed in a deodorizing toilet or an air purifier in a vehicle. The deodorizing honeycomb 8 of the deodorizing member 6 uses the deodorizing sheet 1 of Example 1, and thus has excellent bactericidal properties, antibacterial properties, and deodorizing properties. In addition, since the deodorant sheet 1 of Example 1 is laminated as the two-layer deodorant sheet 5 of Example 2, it becomes a honeycomb shape that has better air permeability than a plurality of deodorant sheets 1 stacked. Sterilization, antibacterial, and early autumn can be performed while performing smooth ventilation from the suction port 71 to the discharge port 72.
As described above, the preferred embodiment of the deodorizing member using the deodorizing sheet in which the spun pieces having bactericidal properties, antibacterial properties, and deodorizing properties are thermally fused to the heat-fusible fiber has been described. The present invention is not limited to the examples. For example, as shown in FIGS. 6 and 7, the deodorizing honeycomb 8 can be laminated differently from FIG. FIG. 6 is a diagram in which the top surface portion 121 of the corrugated sheet deodorizing sheet 5 is shifted and laminated. In addition, in the direction perpendicular to the wave line direction of the two-layer deodorant sheet and from the top surface part 121 to the top surface part 121, the two-layer deodorant sheet is wound to form a honeycomb as a laminated form. It is shown in Thus, it is only necessary that the two-layer deodorizing sheet 5 made of the deodorizing sheet 1 used in the deodorizing member 6 can be laminated to form the honeycomb-shaped deodorizing honeycomb 8. Further, the shape of the case 7 of the deodorizing member 6 has a space for holding the deodorizing honeycomb 8 inside the case 7, and an intake port 71 and a discharge port 72 facing the openings 51 and 52 of the deodorizing honeycomb 8 are provided. It only has to be formed.
