Description

本発明は、空気触媒を付着した繊維と架橋アクリレート系吸放湿性繊維を併用して臭気原因物質を分解除去する能力を飛躍的に高めた寝具用織物または編物に関する。   The present invention relates to a woven fabric or knitted fabric for bedding that dramatically improves the ability to decompose and remove odor-causing substances by using a fiber having an air catalyst attached thereto and a crosslinked acrylate-based moisture-absorbing / releasing fiber.

近年の快適性、健康に対する意識の高まりから、汚染物質を分解または除去する機能を有する素材の開発が強く求められており、これらの機能に基づいて消臭性や抗菌性を有する物質分解除去剤が数多く提案されている。   With the recent increase in comfort and health awareness, there is a strong demand for the development of materials that have the function of decomposing or removing pollutants. Based on these functions, degrading and antibacterial substance decomposition and removal agents Many have been proposed.

特許文献1では、架橋構造およびカルボキシル基を有する重合体から形成され、かつ光触媒活性を有する金属酸化物微粒子を含有する光触媒含有繊維が提案されている。かかる金属酸化物微粒子は、悪臭物質、アレルゲン、菌、ウイルス等がカルボキシル基に吸着されるとともに光触媒で分解される機能を有するが、その機能を発揮するためには十分な光照射が必要であり、しかもカルボキシル基による吸着だけでは分解除去が不十分な物質が存在する問題があった。   Patent Document 1 proposes a photocatalyst-containing fiber that is formed from a polymer having a crosslinked structure and a carboxyl group and contains metal oxide fine particles having photocatalytic activity. Such metal oxide fine particles have a function of adsorbing malodorous substances, allergens, fungi, viruses, etc. to carboxyl groups and decomposing with photocatalysts, but sufficient light irradiation is necessary to exert their functions. In addition, there is a problem that a substance that cannot be decomposed and removed only by adsorption with a carboxyl group exists.

特許文献2では、光照射なしで水酸化ラジカル、オゾン又は過酸化物を発生する空気触媒が固着された繊維構造体が提案されている。空気触媒は物質の分解除去の効果に優れるが、その機能を効果的に発揮するためには周囲に十分な量の水蒸気が持続的に存在することが必要であり、また、空気触媒だけでは分解除去が不十分な物質が存在する問題があった。   Patent Document 2 proposes a fiber structure in which an air catalyst that generates hydroxyl radicals, ozone, or peroxide without light irradiation is fixed. Air catalysts are excellent in decomposing and removing substances, but in order to perform their functions effectively, a sufficient amount of water vapor needs to be continuously present in the surroundings. There was a problem that there was a substance that was insufficiently removed.

特許文献3では、鉄とアルミニウムとカリウムを含む金属組成物、および水を含有する水性組成物からなる消臭剤、抗菌剤、または防カビ剤が提案されている。この水性組成物は、対象物に固着すると水分が蒸発するため、その機能の持続的な発揮には限界があり、また、空気触媒だけでは分解除去が不十分な物質が存在する問題があった。   Patent Document 3 proposes a deodorant, an antibacterial agent, or an antifungal agent comprising a metal composition containing iron, aluminum and potassium, and an aqueous composition containing water. Since this water-based composition evaporates moisture when it adheres to an object, there is a limit to the continuous performance of the function, and there is a problem that there is a substance that is insufficiently decomposed and removed only by an air catalyst. .

上述の特許文献1〜3の問題を解消するために、出願人は、幅広い種類の物質を効果的かつ持続的に分解除去する能力を有する物質分解除去剤を提案した(特許文献4参照)。しかしながら、特許文献4では、これらの物質分解除去剤の機能を寝具用織物または編物において具体的に実現する方法までは提案していなかった。   In order to solve the above-mentioned problems of Patent Documents 1 to 3, the applicant has proposed a substance decomposition / removal agent having the ability to effectively and continuously decompose and remove a wide variety of substances (see Patent Document 4). However, Patent Document 4 has not proposed a method for specifically realizing the function of these substance decomposition and removal agents in bedding fabric or knitted fabric.

本発明は、上述の特許文献4の技術をさらに進めるために創案されたものであり、その目的は、幅広い種類の臭気原因物質を効果的かつ持続的に分解除去する能力を有する寝具用織物または編物を提供することにある。   The present invention was devised in order to further advance the technique of Patent Document 4 described above, and its purpose is to provide a bedding fabric having the ability to effectively and continuously decompose and remove a wide variety of odor-causing substances. To provide knitting.

本発明者は、上記目的を達成するために鋭意検討した結果、寝具用織物または編物において空気触媒を付着した繊維と架橋アクリレート系吸放湿性繊維を併用することにより、架橋アクリレート系吸放湿性繊維によって空気触媒の周囲の水蒸気濃度が持続的に高まり、これにより空気触媒から多量のOHラジカルが発生されて空気触媒の物質分解除去能力を最大限発揮させることができるとともに、これに架橋アクリレート系吸放湿性繊維の物質吸着能力が加わって、幅広い種類の臭気原因物質を分解除去する能力が相乗的に高まることを見い出し、本発明の完成に至った。   As a result of intensive investigations to achieve the above object, the present inventor has found that a cross-linked acrylate-based moisture-absorbing / releasing fiber can be obtained by using both a fiber having an air catalyst attached thereto and a cross-linked acrylate-based moisture-absorbing / releasing fiber in bedding fabric or knitted fabric As a result, the concentration of water vapor around the air catalyst is continuously increased, so that a large amount of OH radicals are generated from the air catalyst to maximize the substance decomposition and removal ability of the air catalyst, and the crosslinked acrylate-based absorbent is also added to this. It was found that the ability of moisture-releasing fibers to adsorb substances was added, and the ability to decompose and remove a wide variety of odor-causing substances was synergistically increased, and the present invention was completed.

即ち、本発明は、以下の(1)〜(4)の構成を有するものである。
(1)鉄、アルミニウム、カリウム、及びチタンを含む金属組成物からなり、かつ金属組成物中の金属含有割合が鉄100ppmに対してアルミニウム100〜500ppm、カリウム0.5〜50ppm、チタン0.1〜50ppmである空気触媒を繊維表面に付着した繊維、及び架橋アクリレート系吸放湿性繊維からなる物質分解除去繊維を含む紡績糸から構成される寝具用織物または編物であって、物質分解除去繊維中の金属組成物の含有量が0.01質量%以上であり、架橋アクリレート系吸放湿性繊維の含有量が50質量%以上であることを特徴とする寝具用織物または編物。

That is, the present invention has the following configurations (1) to (4).
(1) It consists of a metal composition containing iron, aluminum, potassium, and titanium, and the metal content in the metal composition is 100 to 500 ppm of aluminum, 0.5 to 50 ppm of potassium, and 0.1 of titanium with respect to 100 ppm of iron. A bedding fabric or knitted fabric comprising a spun yarn including a fiber having an air catalyst adhering to 50 ppm attached to the fiber surface and a material-removing / removing fiber comprising a cross-linked acrylate-based moisture-absorbing / releasing fiber; The bedding fabric or knitted fabric characterized in that the content of the metal composition is 0.01% by mass or more and the content of the crosslinked acrylate-based moisture-absorbing / releasing fibers is 50% by mass or more.

The bedding fabric or knitted fabric according to (1).
(3) The textile or knitted fabric for bedding according to (1) or (2), wherein the fiber having an air catalyst attached to the fiber surface is a polyester fiber and / or an acrylic fiber.
(4) The bedding fabric or knitted fabric according to any one of (1) to (3), which is used as a side of a comforter, a mattress or a pillow.

本発明の寝具用織物または編物は、架橋アクリレート系吸放湿性繊維の存在により空気触媒の周囲の水蒸気濃度を持続的に高めているので、空気触媒による有機物質及び無機物質(金属を除く)の分解・除去能力を十分に発揮することができ、また架橋アクリレート系吸放湿性繊維による物質の吸着効果も存在するため、幅広い種類の有機物質及び無機物質(金属を除く)に対する分解・除去能力が極めて優れている。従って、本発明の寝具用織物または編物を人間の身体が直接接触する掛け布団又は敷き布団又は枕などの側地に使用した場合、人間由来の臭気原因物質を効果的に分解除去することができる。   The bedding fabric or knitted fabric of the present invention continuously increases the water vapor concentration around the air catalyst due to the presence of the cross-linked acrylate-based moisture-absorbing / releasing fibers, so that organic substances and inorganic substances (excluding metals) produced by the air catalyst are used. Degradation and removal ability can be fully exerted, and there is also an adsorption effect of substances by cross-linked acrylate-based moisture-absorbing / releasing fibers, so it has the ability to decompose and remove a wide variety of organic and inorganic substances (excluding metals). Very good. Therefore, when the textile or knitted fabric for bedding of the present invention is used on a side fabric such as a comforter or a mattress or a pillow that is directly contacted by the human body, the odor-causing substance derived from humans can be effectively decomposed and removed.

本発明の寝具用織物または編物は、特定の金属組成物からなる空気触媒を繊維表面に付着した繊維と、架橋アクリレート系吸放湿性繊維とからなる物質分解除去繊維を含む紡績糸から構成されるものであり、空気触媒と架橋アクリレート系吸放湿性繊維の相乗効果により物質の分解・除去能力を飛躍的に高め、消臭性、抗菌性、抗ウイルス性、防カビ性などを持続的に高いレベルで発揮するものである。   The textile or knitted fabric for bedding according to the present invention is composed of a spun yarn including a fiber with an air catalyst made of a specific metal composition attached to the fiber surface and a material-decomposing and removing fiber made of a crosslinked acrylate-based moisture-absorbing and releasing fiber. It has a high synergistic effect of air catalyst and cross-linked acrylate-based moisture-absorbing / releasing fibers, which dramatically enhances the ability to decompose and remove substances, and continuously has high deodorant, antibacterial, antiviral, and antifungal properties. It is something that is demonstrated at the level.

本発明の物質分解除去繊維において繊維に付着される空気触媒は、化学薬品を使用せずに、触媒効果により空気中の水分と反応してヒドロペルオキシルラジカル及びスーパーオキシドイオンを生成し、有害物質を分解し、さらに抗菌や消臭などの優れた効果を発揮するものである。   The air catalyst attached to the fiber in the material decomposition removal fiber of the present invention generates a hydroperoxyl radical and a superoxide ion by reacting with moisture in the air by a catalytic effect without using chemicals, and is a harmful substance. It exhibits excellent effects such as antibacterial and deodorizing.

空気触媒は、鉄、アルミニウム、カリウム、及びチタンを含む金属組成物からなるものであり、例えば土壌から無機酸または硫酸によって抽出される鉄、アルミニウム、およびカリウムに、四水酸化チタン塩酸塩からのチタンを配合することにより製造されることができる。空気触媒自体は、その作用機序を含め、従来から広く知られており、市販品から入手することが可能である。   The air catalyst is composed of a metal composition containing iron, aluminum, potassium, and titanium. For example, iron, aluminum, and potassium extracted from soil with inorganic acid or sulfuric acid are converted from titanium tetrahydroxide hydrochloride. It can be manufactured by blending titanium. The air catalyst itself, including its mechanism of action, has been widely known so far, and can be obtained from commercial products.

空気触媒中のカリウムは、空気触媒が物質を分解・除去する効果を奏するためのエネルギー源である。カリウムから放出される電子線等が周囲の水分子と衝突し、水和電子、原子状水素、水素ガス、ヒドロキシルラジカル、過酸化水素が生成される。水和電子及び原子状水素は酸化され、ヒドロペルオキシルラジカル及びスーパーオキシドイオンを生成し、ヒドロペルオキシルラジカルは原子状水素とともに過酸化水素を生成する。過酸化水素は鉄により還元され、ヒドロキシラジカル及び水酸化物イオンを生成する(フェントン反応)。過酸化水素は鉄により酸化され、ヒドロペルオキシルラジカル及び水素イオンが生成される。ヒドロキシラジカルとスーパーオキシドイオンは、強い酸化力を有し、これにより物質を分解・除去するとともに、微生物の増殖を阻害する効果を奏する。   Potassium in the air catalyst is an energy source for the air catalyst to have an effect of decomposing and removing substances. Electron beams emitted from potassium collide with surrounding water molecules, and hydrated electrons, atomic hydrogen, hydrogen gas, hydroxyl radicals, and hydrogen peroxide are generated. Hydrated electrons and atomic hydrogen are oxidized to produce hydroperoxyl radicals and superoxide ions, which together with atomic hydrogen produce hydrogen peroxide. Hydrogen peroxide is reduced by iron to generate hydroxy radicals and hydroxide ions (Fenton reaction). Hydrogen peroxide is oxidized by iron to produce hydroperoxyl radicals and hydrogen ions. Hydroxy radicals and superoxide ions have a strong oxidizing power, thereby decomposing / removing substances and inhibiting the growth of microorganisms.

鉄は、上述のようにヒドロキシラジカル及び水酸化物イオンの生成反応(フェントン反応)、並びにヒドロペルオキシルラジカル及び水素イオンの生成反応を促進する。アルミニウムは、対象物または担体への固着・固定のための結合材として機能する。チタンは、アルミニウム、鉄、及びカリウムによる物質分解・除去効果をさらに高める役割を有する。アルミニウム、カリウム及びチタンの含有量は、鉄100ppmに対してそれぞれ100〜500ppm、0.5〜50ppm、0.1〜50ppmの割合であることが好ましい。さらに好ましくは、鉄100ppmに対してそれぞれ100〜300ppm、1〜10ppm、0.1〜5ppmの割合である。また、金属組成物中の鉄含有量は10〜100ppm、アルミニウム含有量は10〜100ppm、カリウム含有量は0.1〜10ppm、チタン含有量は0.01〜1ppmであることが好ましい。   As described above, iron promotes the formation reaction of hydroxy radicals and hydroxide ions (Fenton reaction) and the formation reaction of hydroperoxyl radicals and hydrogen ions. Aluminum functions as a binding material for fixing and fixing to an object or a carrier. Titanium has a role of further enhancing the substance decomposition / removal effect by aluminum, iron, and potassium. The contents of aluminum, potassium, and titanium are preferably 100 to 500 ppm, 0.5 to 50 ppm, and 0.1 to 50 ppm, respectively, with respect to 100 ppm of iron. More preferably, the ratio is 100 to 300 ppm, 1 to 10 ppm, and 0.1 to 5 ppm, respectively, with respect to 100 ppm of iron. Further, the iron content in the metal composition is preferably 10 to 100 ppm, the aluminum content is 10 to 100 ppm, the potassium content is 0.1 to 10 ppm, and the titanium content is preferably 0.01 to 1 ppm.

Moreover, although it does not specifically limit as this fiber, It is preferable to use a polyester fiber and / or an acrylic fiber. As a method for attaching the air catalyst to the fiber, a conventionally known method can be appropriately employed. For example, the air catalyst component is sprayed on the surface of the fiber and dried, or the air catalyst component is dissolved. The method of immersing the fiber in the prepared solution and drying is mentioned.
