Description
本発明は、中間層に十字断面糸を使用することを特徴とするダブルラッセル地、及びこれを用いた加湿機用エアフィルター材に関する。 The present invention relates to a double raschel fabric characterized by using a cross-section yarn for an intermediate layer, and an air filter material for a humidifier using the same.
ダブルラッセル地は表面、裏面、そして表面と裏面とをつなぐ中間層の３層構造を持ち、生地自体にクッション性があることで、それを活かしてベッドマット、椅子地、シューズ等に広く用いられている。また一方で、両面をハニカムメッシュ構造とすることで、通気性が良好であること、形態が安定していることから加湿機用エアフィルター材として用いられている（例えば、特許文献１参照）。 Double raschel has a three-layer structure consisting of a front surface, back surface, and an intermediate layer that connects the front and back surfaces, and the fabric itself has cushioning properties, so it is widely used for bed mats, chairs, shoes, etc. ing. On the other hand, it has been used as an air filter material for a humidifier because it has a honeycomb mesh structure on both sides so that air permeability is good and the form is stable (see, for example, Patent Document 1).
ダブルラッセル地を加湿機用エアフィルター材として用いる上で、加湿量を多くしようとすれば、生地内部の保水量を多くする方法が考えられ、例えば生地密度を大きくしたり、保水能力の高い繊維を使用したりすることが考えられる。しかしながら、生地密度を大きくすれば保水量は多くなるが、同時に水膜ができやすくなるため、生地の通気性が損なわれ、かえって加湿能力として減じることになってしまう。また、保水能力の高い繊維を使用する場合、例えばレーヨンのようなセルロース繊維を使用する場合、通気性は損なわれず、加湿量は向上するが、カビや雑菌が発生しやすく、異臭の原因になる可能性が高いという課題がある。また、捲縮の高いポリエステル繊維を使用する場合には、生地密度を大きくする場合と同様の問題が起こりやすくなるうえ、この糸を中間層に用いた場合は形態が安定しなくなるおそれもある。 When using double raschel as an air filter material for humidifiers, if you want to increase the amount of humidification, there are ways to increase the amount of water retained inside the fabric, such as increasing the fabric density or fiber with high water retention capacity. Can be used. However, if the dough density is increased, the amount of water retained is increased, but at the same time, a water film is easily formed. Therefore, the air permeability of the dough is impaired, and instead the humidifying capacity is reduced. In addition, when using a fiber having a high water retention capacity, for example, when using a cellulose fiber such as rayon, the air permeability is not impaired and the amount of humidification is improved, but mold and germs are easily generated, which causes a strange odor. There is a problem that the possibility is high. In addition, when using highly crimped polyester fibers, the same problems as when the fabric density is increased are likely to occur, and when this yarn is used in the intermediate layer, the form may not be stable.
本発明の目的は、通気性を高く保ちつつ、通気された空気に効率よく水を接触させることのできるダブルラッセル地、及びこれを用いた加湿機用エアフィルター材を提供することである。 An object of the present invention is to provide a double raschel land that can efficiently bring water into contact with aerated air while maintaining high air permeability, and an air filter material for a humidifier using the same.
本発明者らは、前記課題について以下のように鋭意検討した。ダブルラッセル地において、表面、裏面のメッシュ構造部は空気をできるだけ通過させる必要があるため、また、水膜ができにくいようにするため、できるかぎり疎の方がよい。そのため、表面、裏面は膨らみの少ない繊維で、かつ密度が小さい方がよく、つまり表面、裏面の保水量は少ないことになる。従って、この保水を担わせるのは中間層であり、該中間層に液体の移動性が高く、接触面の大きい、さらに、形態安定力の優れた繊維を配することが重要であることが分かった。具体的には、中間層に十字断面を有するモノフィラメントを使用することで、上記課題を解決できることを見出した。 The present inventors diligently studied the above-described problem as follows. In double raschel grounds, the mesh structure on the front and back surfaces should be as sparse as possible in order to allow air to pass through as much as possible and to make it difficult to form a water film. Therefore, it is better that the front and back surfaces are fibers with less swelling and the density is low, that is, the water retention amount on the front and back surfaces is small. Therefore, it is understood that it is important that the intermediate layer is responsible for this water retention, and it is important to arrange fibers with high liquid mobility, large contact surface, and excellent shape stability in the intermediate layer. It was. Specifically, it has been found that the above problem can be solved by using a monofilament having a cross section in the intermediate layer.
すなわち、本発明の第一の構成は、表面、裏面、及びそれらをつなぐ中間層を有するダブルラッセル地において、該中間層の少なくとも一部に十字断面を有するモノフィラメントが用いられることを特徴とするダブルラッセル地である。 That is, the first configuration of the present invention is a double raschel having a front surface, a back surface, and an intermediate layer connecting them, wherein a monofilament having a cross section is used in at least a part of the intermediate layer. Russell.
本発明のダブルラッセル地は、前記十字断面を有するモノフィラメントがポリエステル繊維からなることを特徴とすることが好ましい。 The double raschel fabric of the present invention is preferably characterized in that the monofilament having the cross section is made of a polyester fiber.
また、本発明のダブルラッセル地は、前記十字断面を有するモノフィラメントが１０〜１００ｄＴｅｘの繊度であることを特徴とすることが好ましい。 In the double raschel fabric of the present invention, it is preferable that the monofilament having the cross section has a fineness of 10 to 100 dTex.
前記ダブルラッセル地において、前記十字断面を有するモノフィラメントが中間層全体に対して５０ｗｔ％以上用いられることを特徴とすることが好ましい。 In the double raschel land, the monofilament having the cross section is preferably used in an amount of 50 wt% or more based on the entire intermediate layer.
また、前記ダブルラッセル地は、厚みが２〜１０ｍｍであることを特徴とすることが好ましい。 Moreover, it is preferable that the double raschel ground has a thickness of 2 to 10 mm.
さらに、前記ダブルラッセル地は、前記表面、及び裏面がハニカム構造であることを特徴とすることが好ましい。 Furthermore, it is preferable that the double raschel ground has a honeycomb structure on the front surface and the back surface.
本発明の第二の構成は、前記ダブルラッセル地を用いた加湿機用エアフィルター材である。 The 2nd structure of this invention is the air filter material for humidifiers using the said double Russell ground.
本発明により、通気性量が大きいにも関わらず効果的に水と空気を接触させることができるダブルラッセル地を提供し、その特長を活かし、特に加湿機用エアフィルター材に使用することができる。 According to the present invention, a double raschel fabric that can effectively contact water and air despite having a large air permeability is provided, and its characteristics can be utilized, particularly for an air filter material for a humidifier. .
以下に、本発明について詳細に説明する。
本発明においてダブルラッセル地とは、２列のニードルをもつダブルラッセル機で編み立てられた生地であり、表面、中間層、裏面の３層に区分されていることを特徴としている。８ゲージから２８ゲージまでのダブルラッセル機が一般的であり、本発明に使用される機械は特に限定されない。前記の２列のニードル間は通常「釜間」と呼ばれているが、この釜間についても制約は特になく、通常は１．５ｍｍから１５ｍｍまでが適宜選ばれるが、特に加湿機用エアフィルター材に用いる場合、２〜１３ｍｍの間とすることが好ましい。
The present invention is described in detail below.
In the present invention, the double raschel fabric is a fabric knitted by a double raschel machine having two rows of needles, and is characterized by being divided into three layers: a front surface, an intermediate layer, and a back surface. An 8-gauge to 28-gauge double raschel machine is common, and the machine used in the present invention is not particularly limited. The space between the needles in the two rows is usually called “between the hooks”, but there is no particular restriction on the space between the hooks. Usually, 1.5 mm to 15 mm is appropriately selected. When used as a material, it is preferably between 2 and 13 mm.
本発明のダブルラッセル地に使用される繊維は、表面、中間層、及び裏面のすべてにおいてポリエステル長繊維であることが好ましい。ポリエステル繊維は機械的強度、耐薬品性、変色のしにくさ等から好ましく、長繊維は使用中に付着する析出したカルシウム等を除去することが容易であるため好ましい。 It is preferable that the fiber used for the double raschel fabric of the present invention is a polyester long fiber in all of the front surface, the intermediate layer, and the back surface. Polyester fiber is preferable from the viewpoint of mechanical strength, chemical resistance, resistance to discoloration, and the like, and long fiber is preferable because it is easy to remove precipitated calcium and the like adhering during use.
表面、及び裏面に使用される糸の繊度については特に限定されないが、５６〜７００ｄＴｅｘの使用が一般的である。また、断面形状についても特に限定はなく、丸断面、異形断面いずれも用いることができる。 The fineness of the yarn used for the front surface and the back surface is not particularly limited, but 56 to 700 dTex is generally used. Further, the cross-sectional shape is not particularly limited, and either a round cross-section or an irregular cross-section can be used.
一方、本発明のダブルラッセル地の中間層に使用する糸は、少なくとも一部に、十字断面を有するモノフィラメントを使用することが重要である。十字断面のモノフィラメントを用いることで、空気と触れる面積が増え、さらに水分等の液体の移動性が高いため、通気性を損なうことなく、加湿能力を向上できる。また、該モノフィラメントの繊度は１０〜１００ｄＴｅｘであることが好ましい。繊度が１０ｄＴｅｘより小さいとクッション性に劣り形態安定性が悪くなるため好ましくない。また、１００ｄＴｅｘより大きいと重量が大きくなり、重量に対して面積量が相対的に小さくなるため、コスト面含めメリットがなくなり好ましくない。 On the other hand, it is important to use a monofilament having a cross section at least in part for the yarn used for the intermediate layer of the double raschel fabric of the present invention. By using a monofilament with a cross-section, the area in contact with air is increased, and the mobility of liquid such as moisture is high, so that the humidifying ability can be improved without impairing the air permeability. The fineness of the monofilament is preferably 10 to 100 dTex. If the fineness is less than 10 dTex, the cushioning property is inferior and the form stability is deteriorated. On the other hand, if it is larger than 100 dTex, the weight increases, and the area amount becomes relatively small with respect to the weight.
前記十字断面を有するモノフィラメントは、中間層全体に対して５０ｗｔ％以上使用することが好ましい。５０ｗｔ％未満である場合、例えば、他の使用繊維としてポリエステルマルチフィラメント繊維を選択した場合、形態安定性が低下するおそれがあり、保水量は向上するものの、通気性が著しく阻害されるため好ましくない。また、他の使用繊維として丸断面ポリエステルモノフィラメントを選択した場合、形態安定性、通気性の低下のおそれはないが、保水量、及び空気と接触する面積が減るため好ましくない。 The monofilament having a cross section is preferably used in an amount of 50 wt% or more based on the entire intermediate layer. When it is less than 50 wt%, for example, when a polyester multifilament fiber is selected as another fiber used, there is a risk that the form stability may be lowered and the water retention amount is improved, but the air permeability is remarkably hindered. . Further, when a round cross-section polyester monofilament is selected as the other used fiber, there is no fear of deterioration in form stability and air permeability, but it is not preferable because the water retention amount and the area in contact with air are reduced.
前記十字断面を有するモノフィラメントの製造方法は特に限定されるものでなく、公知の方法を用いて丸断面のモノフィラメントと同様に生産できる。例えば、１ホールのノズルから溶融紡糸して巻き取る方法で作成しても構わないし、複数、具体的には１０のホール数を持つノズルから溶融紡糸して巻き取り、その後分繊工程で作成しても構わない。 The manufacturing method of the monofilament having the cross section is not particularly limited, and can be produced in the same manner as the monofilament having the round section using a known method. For example, it may be prepared by a method of melt spinning from a nozzle of 1 hole and winding it, or a plurality of, specifically, melt spinning and winding from a nozzle having a number of 10 holes, and then preparing by a fiber separation process. It doesn't matter.
本発明のダブルラッセル地は、上記機械、上記繊維を用いて生地を作成するが、組織については特に制約はないものの、加湿機エアフィルター材用途では通気性が重視されるため、表面、及び裏面をハニカム構造にすることが好ましい。また、該用途に用いる場合、厚みが２〜１０ｍｍであることが好ましい。 The double raschel fabric of the present invention creates a fabric using the above machine and the above fibers, but there is no particular restriction on the structure, but in the use of a humidifier air filter material, air permeability is important, so the front and back surfaces Is preferably a honeycomb structure. Moreover, when using for this use, it is preferable that thickness is 2-10 mm.
それらで得られた生地を形態安定のため熱処理して仕上げることが多く、それらの手法について特に制約はない。また、必要に応じ、抗菌、親水等の付帯加工を施す場合もある。 The doughs obtained from these are often heat-treated for form stability, and there are no particular restrictions on these methods. In addition, ancillary processing such as antibacterial and hydrophilic may be performed as necessary.
本発明のダブルラッセル地は、通気性に優れ、通気された空気に効率よく水を接触させることができることから、加湿機用エアフィルター材として好適に用いることができる。 The double raschel fabric of the present invention is excellent in air permeability and can efficiently contact water with the aerated air, so that it can be suitably used as an air filter material for a humidifier.
