れを用いた成形物に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a polyvinyl alcohol (hereinafter abbreviated as PVA) synthetic fiber having excellent bactericidal action and its durability, and a molded article using the same.
〈従来の技術〉
殺菌作用を有する金属イオンを担持したゼオライト系固

ルム等に殺菌能を付与する試みがなされている。<Prior Art> Attempts have been made to incorporate zeolite-based solid particles carrying metal ions having a bactericidal effect into a polymer, and to impart bactericidal ability to fibers, films, etc. made of the polymer.

有させたのでは、殺菌作用を発現させ難いのが実状であ
る。Conventional attempts have been made mainly with polyester and nylon, but metal ions that have a bactericidal effect are activated in the presence of moisture, so if they are included in these hydrophobic polymers, it is difficult to develop a bactericidal effect. The reality is that it is difficult to do so.
また、特開昭６２−１９５０３８号公報には、疎水性の
ポリエステル系高分子にポリエチレンクリコールやスル
ホン化ポリスヂレンなどの親水性物質を練込んで親水性
を付与する技術が開示されている。Further, Japanese Patent Application Laid-Open No. 195038/1983 discloses a technique for imparting hydrophilicity to a hydrophobic polyester polymer by incorporating a hydrophilic substance such as polyethylene glycol or sulfonated polystyrene into the polymer.
しかし、かかる繊維やフィルムも、湿潤状態で長期間使
用すると、その親水性物質が溶出し、親水性を失ってし
まい、殺菌効果が低下してしまう。However, when such fibers and films are used in a wet state for a long period of time, their hydrophilic substances are eluted and they lose their hydrophilicity, resulting in a decrease in their bactericidal effect.
従って、長期間にわたって、その効果を持続しうるもの
は過去に存在しなかったのである。Therefore, there has never been anything in the past that could maintain its effects over a long period of time.

明に至った。Means for Solving the Problems> The present inventors have developed a method for producing target fibers and fibers by mixing zeolite solid particles carrying metal ions with bactericidal activity into polymers that are hydrophilic in nature. We thought that it would be possible to obtain a molded product using this method, and after extensive research, we arrived at the present invention.

られるのである。That is, by selecting a PVA-based polymer as a hydrophilic polymer and adding 0.05% by weight or more of zeolite-based solid particles carrying metal ions with a bactericidal effect to the polymer, the desired fiber can be obtained. It will be done. In addition, the fibers can be used in molded products such as paper and non-woven fabrics with excellent bactericidal action and durability, so that the zeolite solid particles are contained in an amount of 0.05% by weight or more based on the total weight of the molded product. You get something.

ゼオライト系固体粒子とは、アルミノンリケードよりな

殺菌作用のある金属イオンの１種または２種以上をイオ
ン交換により保持したものである。In the present invention, the zeolite-based solid particles supporting metal ions having a bactericidal effect are defined as zeolite-based solid particles that carry one or more metal ions having a bactericidal effect on the ion-exchangeable part of a natural or synthetic zeolite made of aluminone liquede. It was retained through exchange.

るために比表面積が１５０ｍ’／ｇ以上であり、かつ構
成成分の５ｉｆｔ／ Ａ（ｌｔｏｓのモル比が１４以下
であることが必要である。Furthermore, in order to uniformly support metal ions, the zeolite must have a specific surface area of 150 m'/g or more, and a molar ratio of 5ift/A (ltos) of the constituent components must be 14 or less.
ＰＶＡ系高分子に添加する殺菌作用を有する金属イオン

。On the other hand, the PVA-based polymer is not particularly limited as long as it has a fiber-forming ability of 4-4, and has a degree of polymerization of 500, preferably 1000 or more, and a saponification degree of 88 mol% or more, preferably 95 mol% or more. However, especially when it is desired to impart water resistance to PVA-based fibers, a higher degree of saponification is preferable.

以下では効果が不十分である。The spinning stock solution contains 0 zeolite solid particles with respect to PVA.
．． Although an aqueous PVA solution containing 0.5% by weight or more is used, PVA may be dissolved in an aqueous dispersion of zeolite solid particles, or conversely, zeolite solid particles may be added to an aqueous PVA solution. The zeolite solid particles must be contained in an amount of 0.05% by weight or more based on the molded product made of PVA fiber alone or a composite of the PVA fiber and other types of fiber, and if it is less than that, the effect is insufficient. .
かかる紡糸原液は、公知の方法で湿式または、乾式紡糸

ればよい。Such a spinning stock solution may be made into fibers by wet or dry spinning using a known method, followed by roller stretching and mixed heat stretching according to a conventional method, followed by drying, dry heat stretching, and heat treatment as required.
紡糸後の処理を湿熱延伸、あるいは、乾燥で終えた場合
、得られた繊維は、結晶化度が低いため、水溶性で製紙
用バインダー繊維として有用である。When the post-spinning process is completed by wet heat stretching or drying, the resulting fibers have a low degree of crystallinity and are therefore water-soluble and useful as binder fibers for papermaking.
また、延伸、熱処理を施した繊維は結晶化度が高いため
、紙用の主体繊維として用いることが可能であり、これ
ら繊維から不織布などの成形物とすることができる。Further, since the fibers subjected to drawing and heat treatment have a high degree of crystallinity, they can be used as main fibers for paper, and molded products such as nonwoven fabrics can be made from these fibers.

、本発明の繊維の使用量を調整する必要がある。Regarding molded products such as paper and non-woven fabrics using such fibers,
Of course, it is possible to use it by mixing it with other fibrous materials such as bulbs, rayon, polyester, etc., but in order to have a bactericidal effect as a molded product, the zeolite solid particles must be 0.05% of the molded product. It is necessary to adjust the amount of the fiber of the present invention to be used so that the fiber content is at least % by weight.
更に、このような成形物に、別の機能を有する物質（例
えば、吸着能を有する活性炭）を担持させ、殺菌作用に
新たな作用を付加させることもできる。Furthermore, it is also possible to add a new sterilizing effect to such a molded article by supporting a substance with another function (for example, activated carbon having an adsorption ability).

It has features not found in conventional fibers, such as its strong action and long-lasting effect even after long-term use. Therefore, it can be made into any type of molded product such as fiber, paper, non-woven fabric, net, or knitted fabric, and can be used in a wide range of applications such as filters that require sterilizing power, clean cotton, tissue paper, and impact paper. It can be used for.

I got it. (Comparative example 3) When both are unused and 3
Table 3 shows the bacterial reduction rate after washing with running water.
第 ３ 表
本発明の繊維は殺菌作用の持続性がすぐれていることが
明らかである。Table 3 It is clear that the fibers of the present invention have excellent long-lasting bactericidal action.
更に、３ケ月の流水洗による重量減少（溶出）は、実施
例４の繊維は０．５％と殆んどないのに対し、比較例３
の繊維は４７％と大きく、大部分のポリエチレングリコ
ールが溶出し、親水性を失なっていることは想像に難く
ない。Furthermore, the weight loss (elution) after 3 months of washing under running water was 0.5% for the fibers of Example 4, which was almost negligible, whereas the fibers of Comparative Example 3
The fiber content is large at 47%, and it is not hard to imagine that most of the polyethylene glycol has been eluted and the hydrophilicity has been lost.
