Description
本発明は、主としてダニアレルゲンを低減化しうる抗アレルゲン不織布の製造方法に関するものである。 The present invention mainly relates to a method for producing an anti-allergen non-woven fabric capable of reducing mite allergen.
本発明は、特許文献１記載の粘土鉱物とは異なる無機微粒子を抗アレルゲン物質として採用することにより、上記課題を解決したものである。すなわち、本発明は、構成繊維を集積してなる不織布本体に、結合剤、親水化剤及び／又は油剤並びに酸化アルミニウム、二酸化珪素及び酸化亜鉛を含む無機微粒子を含む分散液を付与して、該構成繊維相互間を該結合剤で結合すると共に、該親水化剤及び／又は該油剤並びに該無機微粒子を該不織布本体に付着させることを特徴とする抗アレルゲン不織布の製造方法に関するものである。 The present invention solves the above-mentioned problems by adopting inorganic fine particles different from the clay mineral described in Patent Document 1 as an anti-allergen substance. That is, in the present invention, a dispersion liquid containing a binder, a hydrophilic agent and / or an oil agent, and inorganic fine particles containing aluminum oxide, silicon dioxide and zinc oxide is applied to the non-woven fabric main body formed by accumulating constituent fibers. The present invention relates to a method for producing an anti-allergen nonwoven fabric, which comprises binding the constituent fibers to each other with the binder and adhering the hydrophilic agent and / or the oil agent and the inorganic fine particles to the nonwoven fabric body.
無機微粒子を付着させる不織布本体としては、従来公知のスパンボンド不織布、ニードルパンチ不織布又はスパンレース不織布等が採用される。不織布本体がスパンボンド不織布の場合は、溶融紡糸した長繊維を構成繊維として集積した繊維ウェブに、熱エンボス加工を施し、構成繊維相互間を融着させて得ることができる。また、ニードルパンチ不織布の場合は、繊維ウェブにニードルパンチを施して、構成繊維相互間を絡合させて得ることができる。スパンレース不織布の場合は、繊維ウェブに高圧水流を施して、構成繊維相互間を絡合することにより得ることができる。また、ニードルパンチ、熱エンボス加工及び高圧水流処理を任意に組み合わせて不織布本体を得ることもできる。不織布本体の目付は任意であるが、タフトカーペット用一次基布として用いる場合は、一般的に５０〜２００ｇ／ｍ2程度である。 As the non-woven fabric main body to which the inorganic fine particles are attached, a conventionally known spunbonded non-woven fabric, needle punched non-woven fabric, spunlace non-woven fabric, or the like is adopted. When the non-woven fabric body is a spunbonded non-woven fabric, it can be obtained by heat-embossing a fiber web in which melt-spun long fibers are accumulated as constituent fibers and fusing the constituent fibers to each other. Further, in the case of a needle-punched non-woven fabric, the fiber web can be needle-punched to entangle the constituent fibers with each other. In the case of a spunlace non-woven fabric, it can be obtained by applying a high-pressure water stream to the fiber web and entwining the constituent fibers with each other. Further, a non-woven fabric main body can be obtained by arbitrarily combining needle punching, heat embossing, and high-pressure water flow treatment. The basis weight of the non-woven fabric body is arbitrary, but when it is used as a primary base cloth for a tuft carpet, it is generally about 50 to 200 g / m 2.
無機微粒子を不織布本体に付着させるには、結合剤を用いて付着させる。この結合剤としては、不織布本体の構成繊維相互間を結合するための結合剤と同一のものを採用する。同一の結合剤を採用すると、構成繊維相互間の結合と無機微粒子の付着とが同時に行えるからである。かかる結合剤としては、従来公知のものが採用されるが、アクリル酸エステル系結合剤又はＮＢＲやＳＢＲ等のゴム系結合剤等が用いられる。結合剤は、無機微粒子が分散している分散液中に含有させておき、無機微粒子と共に不織布本体に付与する。分散液中に結合剤を含有させる場合、結合剤の含有量は無機微粒子の含有量と同程度であるのが好ましい。結合剤の含有量が無機微粒子の含有量に比べて少なすぎると、無機微粒子を不織布本体に付着させにくくなる。また、結合剤の含有量が無機微粒子の含有量に比べて多すぎると、結合剤が無機微粒子を完全に被覆して、アレルゲンが無機微粒子と反応しにくくなる。 To attach the inorganic fine particles to the non-woven fabric body, use a binder. As this binder, the same binder as that for binding between the constituent fibers of the non-woven fabric body is adopted. This is because if the same binder is used, the constituent fibers can be bonded to each other and the inorganic fine particles can be attached at the same time. As such a binder, conventionally known ones are adopted, but acrylic acid ester-based binders, rubber-based binders such as NBR and SBR, and the like are used. The binder is contained in the dispersion liquid in which the inorganic fine particles are dispersed, and is applied to the non-woven fabric main body together with the inorganic fine particles. When the binder is contained in the dispersion, the content of the binder is preferably about the same as the content of the inorganic fine particles. If the content of the binder is too small as compared with the content of the inorganic fine particles, it becomes difficult for the inorganic fine particles to adhere to the non-woven fabric body. Further, if the content of the binder is too large as compared with the content of the inorganic fine particles, the binder completely covers the inorganic fine particles, and the allergen becomes difficult to react with the inorganic fine particles.
分散液中には、さらに親水化剤及び／又は油剤を含有させておき、無機微粒子と共に不織布本体に付着させる。親水化剤は、無機微粒子が抗アレルゲン効果を奏するのに有効である。すなわち、親水化剤により水分が吸着され、水分の介在によってアレルゲンが無機微粒子と反応しやくなるのである。親水化剤としては、各種の界面活性剤を用いることができ、具体的には、ポリオキシアルキレンアルキルエーテル系ノニオン界面活性剤やスルホコハク酸系アニオン界面活性剤等が用いられる。分散液中の親水化剤の含有量は若干量であればよく、たとえば、１重量％以下でよい。 The dispersion liquid further contains a hydrophilic agent and / or an oil agent, and is adhered to the non-woven fabric main body together with the inorganic fine particles. The hydrophilizing agent is effective for the inorganic fine particles to exert an anti-allergen effect. That is, water is adsorbed by the hydrophilic agent, and the intervention of water makes it easier for the allergen to react with the inorganic fine particles. As the hydrophilic agent, various surfactants can be used, and specifically, a polyoxyalkylene alkyl ether-based nonionic surfactant, a sulfosuccinic acid-based anionic surfactant, and the like are used. The content of the hydrophilizing agent in the dispersion may be a small amount, for example, 1% by weight or less.
油剤としては、従来公知の繊維油剤を用いることができ、たとえば、シリコーンオイル系や脂肪酸エステル系の合成潤滑油を用いることができる。油剤を無機微粒子と共に繊維本体に付着させることにより、得られた抗アレルゲン不織布にタフティング機の針を貫通させやすくなるのである。すなわち、本発明に係る抗アレルゲン不織布を、タフトカーペット用一次基布の用途に用いる場合、タフティング機の針が抗アレルゲン不織布に通されパイル糸が埋め込まれるのであり、この際、油剤が抗アレルゲン不織布中に存在すると、無機微粒子があっても針を通しやすくなるのである。分散液中における油剤の含有量も、無機微粒子の含有量と同程度であるのが好ましい。油剤の含有量が無機微粒子の含有量に比べて少なすぎると、タフティング機の針が通しにくくなる。また、油剤の含有量が無機微粒子の含有量に比べて多すぎると、油剤の撥水性により、アレルゲンが無機微粒子と反応しにくくなる。 As the oil agent, a conventionally known fiber oil agent can be used, and for example, a silicone oil-based or fatty acid ester-based synthetic lubricating oil can be used. By adhering the oil agent to the fiber body together with the inorganic fine particles, it becomes easy for the needle of the tufting machine to penetrate the obtained anti-allergen non-woven fabric. That is, when the anti-allergen non-woven fabric according to the present invention is used as a primary base cloth for tufted carpet, the needle of the tufting machine is passed through the anti-allergen non-woven fabric and the pile yarn is embedded. When present in the non-woven fabric, it becomes easy for the needle to pass through even if there are inorganic fine particles. The content of the oil agent in the dispersion liquid is also preferably about the same as the content of the inorganic fine particles. If the content of the oil agent is too small compared to the content of the inorganic fine particles, it becomes difficult for the needle of the tufting machine to pass through. Further, if the content of the oil agent is too large as compared with the content of the inorganic fine particles, the water repellency of the oil agent makes it difficult for the allergen to react with the inorganic fine particles.
結合剤、親水化剤及び／又は油剤は、上記したように、無機微粒子の分散液中に含有させて不織布本体に付着させる。さらに、本発明に係る方法で得られた抗アレルゲン不織布に、所望により、消臭剤、抗菌剤、防ダニ剤又は抗ウイルス剤等を、別途付着させてもよい。 Binding agents, hydrophilizing agents and / or oils, as described above, Ru is contained in the dispersion liquid of the inorganic fine particles is adhered to the nonwoven fabric body. Further, if desired, a deodorant, an antibacterial agent, an anti-mite agent, an antiviral agent, or the like may be separately attached to the anti-allergen non-woven fabric obtained by the method according to the present invention.
本発明に係る方法で得られた抗アレルゲン不織布は、種々の用途に用いられるが、上記したタフトカーペット用一次基布として用いるのが好ましい。本発明で用いる無機微粒子はダニアレルゲンに対する反応性が高く、ダニアレルゲンが堆積しやすい、カーペットの材料に適しているからである。なお、本発明で用いる無機微粒子がダニアレルゲンに対して高い反応性を有しているので、その他の各種繊維製品本体に付着して、抗アレルゲン繊維製品を得ることもできる。 The anti-allergen non-woven fabric obtained by the method according to the present invention is used for various purposes, but it is preferably used as the above-mentioned primary base cloth for tuft carpet. This is because the inorganic fine particles used in the present invention are highly reactive with mite allergens and are suitable for carpet materials in which mite allergens are easily deposited. Since the inorganic fine particles used in the present invention have high reactivity with mite allergen, they can be attached to the main body of various other textile products to obtain anti-allergen fiber products.
本発明に係る方法で得られた抗アレルゲン不織布には、酸化アルミニウム、二酸化珪素及び酸化亜鉛を含む無機微粒子が付着している。そして、この無機微粒子はダニアレルゲン等のアレルゲンに対して高い反応性を有しているため、アレルゲンと反応して、それを不活性化させる。したがって、本発明に係る方法で得られた抗アレルゲン不織布が、たとえば、室内や自動車等のカーペットの材料として用いられていると、室内の居住者や自動車の使用者等がアレルギー疾患を発症しにくいという効果を奏する。また、本発明で用いる無機微粒子は、消臭効果、抗菌効果、抗カビ効果及び抗ウイルス効果等も、ある程度併有しているので、これらの効果も奏しうる。 Inorganic fine particles containing aluminum oxide, silicon dioxide and zinc oxide are attached to the anti-allergen non-woven fabric obtained by the method according to the present invention. Since these inorganic fine particles have high reactivity with allergens such as mite allergen, they react with the allergen and inactivate it. Therefore, when the anti-allergen non-woven fabric obtained by the method according to the present invention is used as a material for carpets in indoors and automobiles, for example, indoor residents and automobile users are less likely to develop allergic diseases. It plays the effect. Further, since the inorganic fine particles used in the present invention also have a deodorant effect, an antibacterial effect, an antifungal effect, an antiviral effect and the like to some extent, these effects can also be exhibited.
