〔産業上の利用分野〕
本発明は、抗菌性を有する繊維体に関し、更に詳細には
ガーゼ、包帯等の衛生用品やタオル、シーツ等の日用品
あるいは浄水器のフィルターなどに用いられる抗菌性繊
維体に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a fibrous body having antibacterial properties, and more particularly to sanitary products such as gauze and bandages, daily necessities such as towels and sheets, and filters for water purifiers. The present invention relates to antibacterial fibers used for.
繊維体に抗菌性を付与するために、従来法のような種々
の方法が試みられてきた。Various conventional methods have been attempted to impart antibacterial properties to fibrous bodies.
仁 有機繊維あるいは繊維体自体に有機系抗菌剤を含浸
させ、抗菌効果を付与する方法。A method of impregnating organic fibers or the fiber itself with an organic antibacterial agent to impart an antibacterial effect.
口、有機繊維あるいは繊維自体に銀イオンを担持させ、
抗菌効果を付与する方法。Silver ions are supported on the fibers, organic fibers, or the fibers themselves,
A method of imparting antibacterial effects.
ハ、有機繊維あるいは繊維体にＣｕやＣｕＳを含有させ
て抗菌効果を付与する方法。C. A method of imparting an antibacterial effect by incorporating Cu or CuS into organic fibers or fibrous bodies.
ところが、有機系抗菌剤を用いる方法（上記イ）は、抗
菌剤を有機繊維あるいは繊維体に含浸させているため抗
菌剤の溶出量が多く、毒性および抗菌作用の持続性に問
題がある。銀イオンを担持させる方法（上記口）は、銀
イオンの溶出性に問題がある。つまり、銀をイオンで担
持しているため、金属よりも水中への溶出の割合が高く
、また溶出の速度も大きいため安定性に問題がある。ま
た、銀の溶出速度が大きいことは、銀イオンを担持させ
た繊維体内の銀イオン濃度が短時間で下がり、抗菌作用
の持続性にも問題がある。ＣｕやＣｕＳを含有させる方
法（上記ハ）は、Ｃｕ被覆やＣｕＳ被覆に問題がある。However, in the method using an organic antibacterial agent (a), since the antibacterial agent is impregnated into organic fibers or fibrous bodies, a large amount of the antibacterial agent is eluted, and there are problems with toxicity and sustainability of the antibacterial effect. The method of supporting silver ions (the above method) has a problem with the elution of silver ions. In other words, since silver is supported by ions, the rate of elution into water is higher than that of metals, and the rate of elution is also high, so there is a problem with stability. Furthermore, the high elution rate of silver causes the concentration of silver ions in the fibrous body carrying silver ions to drop in a short time, which also poses a problem in the sustainability of antibacterial action. The method of containing Cu or CuS (above C) has a problem with Cu coating or CuS coating.
Ｃｕ被覆した繊維体を長時間保持しておくと、被覆表面
が酸化して黒くなり、被覆表面が剥離してしまうために
、耐久性に問題があるし、白色や着色を必要とする試料
には使用できない。If a Cu-coated fiber body is kept for a long time, the coated surface will oxidize and turn black, causing the coated surface to peel off, resulting in durability problems. cannot be used.
ＣｕＳ被覆した繊維体は、漂白剤と反応して溶解するの
で洗濯に対して耐久性が悪く、また暗色なので、白色や
着色を必要とする試料には使用できない。CuS-coated fibers react with bleach and dissolve, so they have poor durability against washing, and are dark in color, so they cannot be used for samples that require white color or coloring.
以上のような欠点を改善すべく鋭意努力を重ねた結果、
本発明者等は、殺菌性に優れると共にその調整が容易で
あり、しかも安全で耐久性に優れ、白色であるが故に着
色性を有する汎用性を具えた銀含有抗菌性繊維体を見出
した。As a result of diligent efforts to improve the above-mentioned shortcomings,
The present inventors have discovered a silver-containing antibacterial fiber that has excellent bactericidal properties, is easy to adjust, is safe, has excellent durability, and has colorability because it is white and has versatility.
本発明は、銀が金属の状態で含有されており、銀イオン
の溶出量がＩ ＰＰｂ以上１ ｐｐｍ以下であることを
特徴とする銀含有抗菌性繊維体を提供する。The present invention provides a silver-containing antibacterial fiber containing silver in a metallic state and having an elution amount of silver ions of IPPb or more and 1 ppm or less.
本発明の銀含有抗菌性繊維体は金属状態の銀を含有した
繊維体であって、具体的には、繊維体を構成する有機繊
維に予め銀を被覆した後に繊維体に加工したものである
。The silver-containing antibacterial fibrous body of the present invention is a fibrous body containing silver in a metallic state, and specifically, the organic fiber constituting the fibrous body is coated with silver in advance and then processed into a fibrous body. .
銀を金属でなくイオンの状態で担持させた場合には、こ
の状態で水中に保持した際に銀イオンの溶出量が多くな
る問題があり、また銀が繊維体の極薄い層にしか担持さ
れないので銀の絶対量が少なく、持続性にも問題がある
。If silver is supported in the form of ions rather than metal, there is a problem that when it is held in water in this state, the amount of silver ions eluted increases, and silver is supported only in a very thin layer of the fiber body. Therefore, the absolute amount of silver is small, and there are problems with sustainability.
そこで、本発明の銀含有抗菌性繊維体は、銀を金属状態
で含有させることにより、銀イオンの溶出量Ｉ ＰＰｂ
以上１ ｐｐｍ以下に制御した。銀イオン濃度がＩ Ｐ
ｐｂより少ないと、溶出銀による殺菌効果が小さく実際
上効果が現れない。一方、銀イオン濃度が１ ｐｐｍよ
り多いと、溶出銀により環境上の問題が生じる可能性が
あり好ましくない。Therefore, the silver-containing antibacterial fiber of the present invention contains silver in a metallic state, so that the elution amount of silver ions I PPb
The content was controlled to 1 ppm or less. Silver ion concentration is I P
When the amount is less than pb, the bactericidal effect of eluted silver is so small that no practical effect is exhibited. On the other hand, if the silver ion concentration is more than 1 ppm, the eluted silver may cause environmental problems, which is not preferable.

持続性が無い。The silver-containing antibacterial fiber of the present invention was placed in tap water at 25°C for 24 hours.
The figure shows the change over time in the amount of silver ions eluted (curve 1) when immersion was repeated over time. For comparison, change over time in the amount of silver ions eluted from a conventional antibacterial fiber carrying silver ions C
Song m2) is also shown. The vertical axis of the figure is the amount of silver ions eluted, and the horizontal axis is the number of immersions for 24 hours. The figure uses values obtained when 10 g of the sample is immersed in 1 liter of tap water. curve 1
As shown in FIG.
It is constant and persistent in the ppb range. On the other hand, in the conventional fibrous body, as shown in curve 2, the amount of silver eluted gradually decreases and is not sustainable.
本発明の銀含有抗菌性繊維体は、予め銀を含有させた有
機繊維と銀を含有しない有機繊維を任意の割合で混合し
た後に繊維体にすることによって得られる。このような
方法で銀を含有させ、繊維体中の銀の濃度を任意の割合
で変化させることにより銀の溶出の割合を制御できる。The silver-containing antibacterial fibrous body of the present invention can be obtained by mixing organic fibers containing silver and organic fibers not containing silver in an arbitrary ratio and then forming the mixture into a fibrous body. By incorporating silver using such a method and changing the concentration of silver in the fiber body at an arbitrary rate, the rate of silver elution can be controlled.
しかも、繊維体内に均一にしかも安定に銀を含有させる
ことができるので、抗菌性が均一に保持される。Moreover, since silver can be contained uniformly and stably within the fiber body, antibacterial properties are maintained uniformly.
本発明に用いられる有機繊維とは、天然及び合成の有機
物繊維、すなわち綿、麻、再生セルロース、ポリアミド
、アクリル、ポリオレフィン、ポリエステル等の繊維で
ある。有機繊維の太さは、０．１〜１５ｄ（デニール）
が好ましい、 ０．１ｄより細いと銀の被覆量を多く必
要として経済的でなく、また１５ｄより太いと繊維が硬
くなり可撓性が失われる。The organic fibers used in the present invention include natural and synthetic organic fibers, ie, fibers such as cotton, hemp, regenerated cellulose, polyamide, acrylic, polyolefin, and polyester. The thickness of organic fiber is 0.1 to 15 d (denier)
is preferable. If it is thinner than 0.1 d, a large amount of silver coating is required and it is not economical. If it is thicker than 15 d, the fiber becomes hard and loses its flexibility.
有機繊維に金属銀を含有させる方法は、無電解めっき法
、真空蒸着法などがあり、均一性、量産性、経済性につ
いて考慮すると、無電解めっき法により銀を被覆する方
法が好ましい。銀の被覆量は任意に選択することができ
る。好ましい銀含有量は１０重量％から３０重量％であ
る。１０重量％未満では繊維を充分に被覆できず、また
３０重量％を越えると繊維全体の比重が大きくなるうえ
抗菌効果も頭打ちとなるので好ましくない、めっき液中
の銀イオンはすべて還元析出されるので、繊維の量に対
し、被覆量に相当する量の銀イオンを含むめっき液を使
用することにより希望の被覆量を得ることができる。Methods for incorporating metallic silver into organic fibers include electroless plating methods, vacuum evaporation methods, and the like. Considering uniformity, mass productivity, and economic efficiency, it is preferable to coat the organic fibers with silver using electroless plating methods. The amount of silver coating can be arbitrarily selected. The preferred silver content is 10% to 30% by weight. If it is less than 10% by weight, the fibers cannot be sufficiently coated, and if it exceeds 30% by weight, the specific gravity of the entire fiber increases and the antibacterial effect reaches its peak, which is undesirable. All silver ions in the plating solution are reduced and precipitated. Therefore, the desired amount of coating can be obtained by using a plating solution containing silver ions in an amount corresponding to the amount of coating with respect to the amount of fibers.

It also includes primary processed products made by processing organic fibers into non-woven fabrics, and secondary or higher processed products made from them, such as wall materials.

Therefore, it has high reliability. Furthermore, since it is white to silvery white, it is preferable for sanitary products and is also excellent in coloring. Furthermore, although it has a bactericidal effect, it can be safely used even if it comes into contact with the human body because it is made of metallic silver.
