Description
【０００１】
【産業上の利用分野】
本発明は、人体、生物に障害を与えることなく、繊維製品に耐久性のある抗菌性、保湿性、紫外線遮断性等の多機能を付与するものである。
【０００２】
【従来の技術】
繊維製品、殊にポリエステル繊維のような合成繊維を主体とする繊維製品に、人体には安全で、しかも耐久性のある抗菌性、紫外線遮断性を付与することは決して容易なことではなく、古くから殺菌剤、抗菌剤、紫外線遮断剤が繊維処理剤として用いられているにもかかわらず満足な結果をもたらすものは得られていない。
【０００３】
特に最近ではＭＲＳＡのような耐性菌の出現により、抗生物質が抗菌性万能とはいえなくなり、このような耐性菌への配慮も必要となっている。
【０００４】
更に、ジフェニルエーテル系の抗菌剤のように加工繊維の焼却時に、発がん物質のダイオキシンが生成する事例が報告されるなど、環境への配慮も必要となっている。
【０００５】
これに対して耐性菌に対しても強い抗菌性を示し、かつ発がん物質の生成もない抗菌剤、紫外線遮断剤として、ゼオライトの銀、銅もしくは亜鉛のイオン交換体等の無機化合物が試みられているが、耐洗濯性に乏しいのが欠点である。
【０００６】
周期表第Ｉｂ族、第ＩＩａ族、第ＩＩｂ族、第ＩＩＩｂ族または第ＩＶｂ族金属の水溶性塩は、殺菌剤として知られている。例えば銀、銅、亜鉛等の水溶性塩は人畜に対して障害の少ない殺菌剤として古くから知られているが、これを繊維製品に適用した場合、耐洗濯性が乏しいのが難点である。
【０００７】
一方、キトサン有機酸塩は、繊維製品の処理剤として知られ、若干の抗菌性を有することも知られているが、これのみで充分な抗菌性を得ることはできない。
【０００８】
また特開平４−１９３２７５号には、無機あるいは有機の粉末状物にキトサンを固定化し、その後に原子番号１２〜１３、２０〜３０、３８〜５１、５７〜８３及び８８〜８９の金属元素からなる群より選ばれた一種又は二種以上の金属元素を固定化させて粉末状消臭材料を得る技術が記載されている。
【０００９】
上記先行技術では、処理手段は、本発明と似ているが、耐久性のある殺菌性、紫外線遮断性の付与について、なんらの示唆もなされていない。
【００１０】
一方、最近、肌に触れる衣料、例えは下着、寝衣、ベッドシーツなどに対する消費者の要望として衛生的であるとともに着心地の良さ、即ち適度の吸湿性、吸水性の付与が要求されているが、キトサンと金属元素のみによる処理は、吸湿性、吸水性の点では充分とはいえない。
【００１１】
本発明者らは、殺菌性があって、衛生的であるとともに、紫外線遮断性、適度の吸湿性、吸水性を有する繊維製品を得るべく研究を続けた結果、本発明に達した。
【００１２】
【発明が解決しようとする課題】
即ち、本発明は、前述した従来の抗菌性、紫外線遮断性繊維製品の欠点を改良して、耐洗濯性が優れ、かつ人体、生物等に障害のない抗菌性繊維製品を得るとともに、着心地を改善するための保湿性、吸湿性を合わせて得るものである。
【００１３】
【課題を解決するための手段】
本発明は、天然、再生もしくは合成繊維からなる繊維製品であって、▲１▼周期表第ＩＩａ族、第ＩＩｂ族、第ＩＩＩｂ族及び／または第ＩＶｂ族金属の酸化物（平均粒子径が５μ以下）、▲２▼キトサン及び▲３▼水溶性アクリル酸系ポリマーまたはその水溶性塩を必須成分とする混合物もしくは複合体が、該繊維製品に対して金属換算含有率として０．０２〜３重量％、キトサン含有率として０．０１〜７重量％、金属酸化物の金属換算含有率として０．０２〜３重量％、水溶性アクリル酸系ポリマーの水溶性塩含有率として０．０１〜５重量％含有されていることを特徴とするものである。
【００１４】
ここに複合体とは、構成要素物質同士が塩、錯塩を形成したり、物理的に結合されたものを意味する。
【００１５】
本発明に使用する天然、再生もしくは合成繊維としては、綿、麻、羊毛等の天然繊維、レイヨン等の再生繊維、ポリエステル、ポリアミド、ポリアクリロニトリル等の合成繊維等が挙げられ、単独もしくは複合されて繊維、糸、織物、編物、不織布、紙等の状態で使用される。
【００１６】
本発明に使用する微粒子状金属酸化物は、平均粒子径が５μ以下、好ましくは１．０μ以下であって、粒子径が小さい程、水に対する懸濁状態が安定となり、均一かつ耐久性の優れた繊維加工をすることができる。紫外線遮断性も向上する。
【００１７】
金属酸化物の例としては前述したとおり、第ＩＩａ族のマグネシウム、カルシウム、第ＩＩｂ族の亜鉛、第ＩＩＩｂ族のアルミニウム、第ＩＶｂ族の錫の酸化物が好ましいものである。特に好ましい酸化物としては、亜鉛の酸化物が挙げられる。上記金属の酸化物の繊維製品に対する付着量は、金属換算含有率で０．０２〜３重量％、好ましくは０．１〜２重量％である。金属酸化物の量が多すぎると着色、変色、劣化等の障害が多いのみでなく、金属酸化物の脱落も多く、脱落物による弊害も起こる。
【００１８】
本発明に使用するキトサンは蟹等の甲殻類や「きのこ」等から得られるキチンを高濃度のアルカリで処理して脱アセチル化して得られる遊離アミノ基を有するものであり、脱アセチル化度は３０％以上が好ましい。
【００１９】
また上記キトサンは、通常有機酸塩として使用されるが、該有機酸としては、酢酸、修酸、乳酸、蟻酸、りんご酸等が例示される。特に好ましい酸は、酢酸、修酸、乳酸である。
【００２０】
キトサンの繊維製品への付着量は、０．０１〜７重量％であって、０．１〜５重量％が好ましい。付着量が大きすぎると繊維が黄変したり、風合が硬化する障害が生ずる。従って上記金属酸化物とキトサンとの混合物もしくは複合体の繊維に対する含有量は０．０３〜８重量％であることが好ましい。
【００２１】
上記金属酸化物とキトサン及びアクリル酸系ポリマーは、少なくとも一部が複合体を形成して被処理繊維上に耐洗濯性の優れた皮膜を形成し、特にキトサン塩は繊維に対して親和性が強いために耐洗濯性の優れた抗菌性繊維を得ることができる。
【００２２】
本発明に使用するアクリル酸系ポリマーは、アクリル酸またはメタアクリル酸単独もしくは、これらを主体として、少量の（メタ）アクリル酸エステル、アクリロニトリル、酢酸ビニルのようなビニル系化合物、エチレン、プロピレンのようなオレフィン系化合物等を共重合した水溶性ポリマーまたはそのソーダ塩、アンモニウム塩等の水溶性塩であり、その使用量は繊維に対して０．０１〜５重量％が好適である。
【００２３】
アクリル酸系ポリマーまたはその水溶性塩は、繊維の表層部で、アクリル酸系ポリマーの持つカルボン酸基もしくはカルボン酸塩の基の一部がキトサンと結合してポリマー同士の結合体もしくは複合体を形成し、繊維製品に強固に接着されるとともにそれ以外の遊離状態のカルボン酸基もしくはカルボン酸塩の基は保湿性能、吸水性能を付与するものと考えられる。
【００２４】
上記繊維製品に上記金属酸化物とキトサン塩、ポリアクリル酸系ポリマーとを付与する手段としては、常法に従って上記各薬剤の水分散液をパッディング法、浸漬法等の手段を用いて施せばよい。ただし、この際、キトサン塩濃度は２０％以下で、ｐＨは３〜６の範囲にあることが好ましい。これは上記金属酸化物とキトサン塩とが複合体を作って、耐久性が発現する条件である。
【００２５】
更に、これら複合体は繊維製品上で確実かつ緊密に形成されることが耐久性を得る点で好ましく、そのためには、上記金属の酸化物、キトサン有機酸塩及びアクリル酸系ポリマーを別々に繊維製品に付与する（順序を問わない）のが好ましい。
【００２６】
なお、この処理とともに染料、蛍光漂白剤、帯電防止剤、柔軟剤、風合調節剤等を適宜添加してもさしつかえない。
【００２７】
次に実施例について、本発明を更に詳細に説明する。なお、実施例中、抗菌性、吸水性、保湿性、紫外線遮断性等の試験は次の方法で行った。

【発明の効果】
実施例で示したように、本発明の製品は、耐洗濯性が優れた抗菌性、紫外線遮断性を示し、合わせて保湿性が格段に優れていて、着心地が著しく向上している。[0001]
[Industrial applications]
The present invention imparts durable antibacterial properties, moisturizing properties, ultraviolet blocking properties, and other multifunctional features to textiles without damaging the human body or living organisms.
[0002]
[Prior art]
It is not easy to provide textile products, especially textile products mainly composed of synthetic fibers such as polyester fibers, with a safe, durable antibacterial property and ultraviolet blocking property for the human body. Although no fungicide, antibacterial agent, or ultraviolet ray blocking agent has been used as a fiber treatment agent, none of them has yielded satisfactory results.
[0003]
In particular, recently, with the emergence of resistant bacteria such as MRSA, antibiotics cannot be said to be all-purpose antibacterial agents, and it is necessary to pay attention to such resistant bacteria.
[0004]
In addition, it is necessary to consider the environment, for example, it has been reported that dioxin, a carcinogen, is generated during incineration of processed fibers like diphenyl ether-based antibacterial agents.
[0005]
On the other hand, inorganic compounds such as zeolite silver, copper or zinc ion exchangers have been tried as antibacterial agents that exhibit strong antibacterial properties against resistant bacteria and do not generate carcinogens, and as ultraviolet ray blocking agents. However, the drawback is that the washing resistance is poor.
[0006]
Water-soluble salts of Group Ib, IIa, IIb, IIIb or IVb metals of the Periodic Table are known as fungicides. For example, water-soluble salts such as silver, copper, and zinc have long been known as fungicides with little hindrance to humans and animals. However, when they are applied to textiles, they are disadvantageous in that they have poor washing resistance.
[0007]
On the other hand, chitosan organic acid salt is known as a treating agent for textile products and is also known to have some antibacterial properties, but it is not possible to obtain sufficient antibacterial properties by itself.
[0008]
Japanese Patent Application Laid-Open No. 4-193275 discloses that chitosan is immobilized on an inorganic or organic powdery substance, and thereafter, a metal element having an atomic number of 12 to 13, 20 to 30, 38 to 51, 57 to 83 and 88 to 89 is used. There is described a technique for obtaining a powdery deodorant material by immobilizing one or more metal elements selected from the group consisting of:
[0009]
In the above prior art, the processing means is similar to that of the present invention, but there is no suggestion of imparting durable bactericidal and ultraviolet blocking properties .
[0010]
On the other hand, recently, consumers are required to provide clothing that touches the skin, for example, underwear, sleeping clothes, bed sheets, and the like, as well as being hygienic and comfortable to wear, that is, imparting appropriate hygroscopicity and water absorption. However, treatment with chitosan and a metal element alone is not sufficient in terms of moisture absorption and water absorption.
[0011]
The present inventors have conducted research on obtaining a fiber product having sterilizing properties, sanitary properties , ultraviolet ray blocking properties , moderate hygroscopicity, and water absorbency, and as a result, have reached the present invention.
[0012]
[Problems to be solved by the invention]
That is, the present invention improves the above-mentioned drawbacks of the conventional antibacterial and ultraviolet-blocking fiber products, and provides an antibacterial fiber product having excellent washing resistance and no harm to the human body, living things, etc. It is obtained by combining the moisturizing property and the hygroscopic property for improving the quality.
[0013]
[Means for Solving the Problems]
The present invention is, naturally, a textile and a reproducing or synthetic fibers, ▲ 1 ▼ Group IIa of the periodic table, Group IIb, Group IIIb and / or Group IVb metal oxides (average particle size of 5μ The mixture or composite containing (2 ) chitosan and (3 ) a water-soluble acrylic acid-based polymer or a water-soluble salt thereof as an essential component is 0.02 to 3% by weight in terms of metal relative to the fiber product. %, 0.01 to 7% by weight chitosan content, 0.02 to 3% by weight in terms of metal content of the metallic oxide, as a water-soluble salt content of the water-soluble acrylic acid-based polymer 0.01 to 5 % By weight.
[0014]
Here, the complex means a substance in which constituent materials form salts or complex salts or are physically bonded.
[0015]
Examples of the natural, regenerated or synthetic fibers used in the present invention include natural fibers such as cotton, hemp, and wool, regenerated fibers such as rayon, and synthetic fibers such as polyester, polyamide, and polyacrylonitrile. It is used in the form of fibers, yarns, woven fabrics, knits, non-woven fabrics, papers, and the like.
[00 16]
The fine particle metal oxide used in the present invention has an average particle diameter of 5 μm or less, preferably 1.0 μm or less, and the smaller the particle diameter, the more stable the suspension state in water, and the uniform and excellent durability. Fiber processing can be performed. UV blocking properties are also improved.
[00 17]
As described above as examples of the metal oxides, magnesium group IIa, calcium, zinc of a Group IIb, Group IIIb aluminum, those oxides of Group IVb of tin are preferred. Particularly preferred oxides, oxides of zinc and the like. Weight adhesion to textile products the metal oxides is 0.02 to 3 wt% in terms of metal content is preferably 0.1 to 2 wt%. Coloring the amount of metallic oxide is too much, discoloration, not only many disorders such as degradation, many falling gold Shokusan products also occur adverse effects of dropping thereof.
[00 18 ]
The chitosan used in the present invention has a free amino group obtained by treating a chitin obtained from a crustacean such as a crab or a `` mushroom '' with a high-concentration alkali and deacetylating the chitin. 30% or more is preferable.
[00 19 ]
The chitosan is generally used as an organic acid salt, and examples of the organic acid include acetic acid, oxalic acid, lactic acid, formic acid, and malic acid. Particularly preferred acids are acetic, oxalic and lactic acids.
[00 20 ]
The amount of chitosan attached to the textile is 0.01 to 7% by weight, preferably 0.1 to 5% by weight. If the amount is too large, the fibers may turn yellow or the hand may harden. Therefore mixtures or content for fibers of the complex with the metals oxide and chitosan is preferably from 0.03 to 8% by weight.
[00 21 ]
At least a part of the metal oxide, chitosan and acrylic acid-based polymer forms a complex to form a film having excellent washing resistance on the fiber to be treated. In particular, chitosan salt has an affinity for the fiber. Since it is strong, antibacterial fibers having excellent washing resistance can be obtained.
[00 22 ]
The acrylic acid polymer used in the present invention may be acrylic acid or methacrylic acid alone or, mainly, a small amount of a (meth) acrylic acid ester, acrylonitrile, a vinyl compound such as vinyl acetate, or ethylene or propylene. Or a water-soluble polymer such as a soda salt or an ammonium salt thereof obtained by copolymerizing a suitable olefinic compound or the like, and the amount thereof is preferably 0.01 to 5% by weight based on the fiber.
[00 23 ]
Acrylic acid-based polymer or its water-soluble salt forms a conjugate or complex of polymers by binding a part of carboxylic acid group or carboxylate group of acrylic acid-based polymer to chitosan at the surface layer of the fiber. It is considered that the carboxylic acid group or carboxylate group which is formed and firmly adhered to the fiber product and which is in a free state other than the above imparts moisturizing performance and water absorbing performance.
[00 24 ]
The gold Shokusan product chitosan salt to the textile, as a means for applying a polyacrylic acid polymer, padding method moisture dispersion liquid of each agent in a conventional manner, Hodokose by means of a dipping method, etc. Just fine. However, in this case, the chitosan salt concentration is preferably 20% or less, and the pH is preferably in the range of 3 to 6. This is a condition under which the metal oxide and the chitosan salt form a complex to exhibit durability.
[00 25]
In addition, these complexes are preferred from the viewpoint of obtaining the durability to be reliably and closely formed on the textiles. For this purpose, the metal oxides, chitosan organic acid salts and fibers separately acrylic acid polymer It is preferably applied to the product (in any order).
[00 26]
In addition, a dye, a fluorescent bleach, an antistatic agent, a softening agent, a feeling control agent and the like may be appropriately added together with this treatment.
[00 27]
Next, the present invention will be described in more detail with reference to examples. In the examples, tests such as antibacterial properties, water absorption properties, moisture retention properties, and ultraviolet ray blocking properties were performed by the following methods.
[00 28 ]
Antibacterial property: After preparing a suspension of test bacteria (Staphylococcus aureus) of 1 to 2 × 10 4 / ml by a shake flask method, the number of viable bacteria is measured. Next, 0.75 g of the test piece was added, and the mixture was shaken at 25 ° C. and 320 rpm for 1 hour. Then, the viable cell count was measured again, and the sterilization rate was obtained by the following formula.
Moisturizing property: Moisture retention (1) after the test piece was left in an atmosphere of 20 ° C. and 65% RH for 48 hours, and moisture content (2) after being left in an atmosphere of 20 ° C. and 95% RH for 60 minutes. .
