Water or an organic solvent is preferably used depending on the type of silver ions or silver colloidal particles, which are silver components, or urea, glycerin, polyethylene glycol, fluororesin, silicone resin, or the like, which is an additive. For example, water is preferable as a solvent for silver ions, and water or an organic solvent such as ethanol, 1-propanol, and 2-propanol is preferable as a dispersion medium for silver colloidal particles. Further, water or an organic solvent such as ethanol, 1-propanol, and 2-propanol is preferable for a solvent such as urea, glycerin, and polyethylene glycol, and n-hexane, n-heptane, Organic solvents such as dichloromethane, ethanol, 1-propanol, 2-propanol are preferred. Further, the solvent may be mixed and used according to the kind and content of the silver component and the additive.
本発明における銀含有液中の銀成分としては、銀イオンおよび銀コロイド粒子からなる群から選ばれる少なくとも１つを含む。銀イオンの生成方法には、特に制限はなく、たとえば、以下の方法により銀イオンが得られる。水を、陽極に銀電極、陰極にチタン電極を用いて、陽極と陰極との間に隔膜を設けることなく電気分解（無隔膜電解という、以下同じ）することによって、陽極中の銀が陽極酸化されて水中に溶出して、銀含有液である銀イオン含有水が得られる。 The silver component in the silver-containing liquid in the present invention includes at least one selected from the group consisting of silver ions and silver colloid particles. There is no restriction | limiting in particular in the production | generation method of silver ion, For example, silver ion is obtained with the following method. By using water and silver electrode for the anode and titanium electrode for the cathode and electrolyzing without providing a diaphragm between the anode and the cathode (hereinafter referred to as non-membrane electrolysis), the silver in the anode is anodized. Then, elution into water yields silver ion-containing water which is a silver-containing liquid.
また、銀コロイド粒子の生成方法には、特に制限はなく、たとえば銀の微粒子を分散剤とともに水中または有機溶媒中に分散させることにより行なう。銀濃度の高い銀コロイド液は、水または有機溶媒で希釈されることにより、銀濃度を低減できる。こうして得られる銀コロイド液（これは、銀含有液である）において、銀の微粒子が銀コロイド粒子として安定化されている。 The method for producing silver colloidal particles is not particularly limited. For example, silver colloidal particles are dispersed in water or an organic solvent together with a dispersant. A silver colloid solution having a high silver concentration can be reduced by being diluted with water or an organic solvent. In the silver colloid liquid thus obtained (this is a silver-containing liquid), silver fine particles are stabilized as silver colloid particles.
銀含有液中の銀成分の銀換算濃度は、特に制限はないが、０．０１ｐｐｍ以上１０ｐｐｍ以下であることが好ましい。銀換算濃度が０．０１ｐｐｍ未満であると十分な消臭、抗菌または防黴効果が得られず、銀換算濃度が２０ｐｐｍを超えると時間の経過とともに銀による着色が大きくなる。かかる観点から、銀中の銀成分の銀換算濃度は０．１ｐｐｍ以上１０ｐｐｍ以下であることがより好ましい。ここで、銀成分の銀換算濃度は、ＩＣＰ−ＡＥＳ（誘導結合プラズマ原子分光分析）により、銀イオンに換算された濃度として得られる。 Although the silver conversion density | concentration of the silver component in a silver containing liquid does not have a restriction | limiting in particular, It is preferable that they are 0.01 ppm or more and 10 ppm or less. If the silver equivalent concentration is less than 0.01 ppm, sufficient deodorizing, antibacterial or antifungal effects cannot be obtained, and if the silver equivalent concentration exceeds 20 ppm, the coloration with silver increases with time. From this viewpoint, the silver equivalent concentration of the silver component in silver is more preferably 0.1 ppm or more and 10 ppm or less. Here, the silver conversion density | concentration of a silver component is obtained as a density | concentration converted into silver ion by ICP-AES (inductively coupled plasma atomic spectroscopy).
本発明における銀含有液中の用いられる銀コロイド粒子の平均直径は、特に制限はないが、０．５ｎｍ以上１００ｎｍ以下であることが好ましい。銀コロイド粒子の平均直径が小さくなるほど銀コロイドによる消臭、抗菌および防黴効果は大きくなるが、平均直径が０．５ｎｍ未満の銀コロイド粒子を形成することは困難であり、平均直径が１００ｎｍを超えると銀コロイド粒子による消臭、抗菌または防黴効果が低減する。 The average diameter of the silver colloid particles used in the silver-containing liquid in the present invention is not particularly limited, but is preferably 0.5 nm or more and 100 nm or less. Although the deodorizing, antibacterial and antifungal effects due to the silver colloid increase as the average diameter of the silver colloid particles decreases, it is difficult to form silver colloid particles having an average diameter of less than 0.5 nm. If exceeded, deodorizing, antibacterial or antifungal effects due to the colloidal silver particles are reduced.
また、本発明おける銀含有液に含まれる添着剤の濃度は、０．１ｇ／ｌ以上１００ｇ／ｌ以下であることが好ましい。添着剤の濃度が０．１ｇ／ｌ未満であると繊維製品への銀イオンおよび銀コロイド粒子の添着性が低下し、１００ｇ／ｌを超えると繊維製品のべとつき感が大きくなる。かかる観点から、添着剤の濃度は、１ｇ／ｌ以上５０ｇ／ｌ以下であることがより好ましい。なお、ｌはリットルを示す。 Further, the concentration of the additive contained in the silver-containing liquid in the present invention is preferably from 0.1 g / l to 100 g / l. If the concentration of the additive is less than 0.1 g / l, the adhesion of silver ions and silver colloidal particles to the fiber product decreases, and if it exceeds 100 g / l, the stickiness of the fiber product increases. From such a viewpoint, the concentration of the additive is more preferably 1 g / l or more and 50 g / l or less. In addition, l shows a liter.
本発明に用いられる添着剤は、銀成分中の銀イオンおよび銀コロイド粒子を安定に保持し、繊維製品に添着させるものであれば特に制限はない。添着剤は、繊維製品への添着性が高い観点から、尿素、グリセリン、ポリエチレングリコール、フッ素樹脂、シリコーン樹脂などが好ましい。ここで、ポリエチレングリコールの分子量は、繊維製品への添着性を高める観点から低分子量のものが好ましく、たとえば数平均分子量が１００〜４００のものが好ましい。また、フッ素樹脂、シリコーン樹脂は、繊維製品の表面上に開口部を有するコーティング層を形成するため、繊維製品への添着性が特に高くなる。ここで、フッ素樹脂またはシリコーン樹脂は、有機溶媒に溶解または分散して繊維製品に塗布されることができ、乾燥により開口部を有する膜を形成するものであれば特に制限はないが、繊維製品への添着性を高める観点から低分子量のものが好ましい。 The additive used in the present invention is not particularly limited as long as it can stably hold silver ions and silver colloid particles in the silver component and can be attached to the fiber product. The additive is preferably urea, glycerin, polyethylene glycol, a fluororesin, a silicone resin, or the like from the viewpoint of high attachment to a fiber product. Here, the molecular weight of the polyethylene glycol is preferably a low molecular weight from the viewpoint of enhancing the attachment property to the fiber product, and for example, the number average molecular weight is preferably 100 to 400. Moreover, since the fluororesin and the silicone resin form a coating layer having an opening on the surface of the fiber product, the attachment property to the fiber product is particularly high. Here, the fluororesin or silicone resin is not particularly limited as long as it can be applied to the fiber product by being dissolved or dispersed in an organic solvent and can form a film having an opening by drying. From the viewpoint of enhancing the adhesion to the resin, those having a low molecular weight are preferable.
