Description
本発明は、ポリエステル繊維等の合成繊維類、アセテート繊維等の半合成繊維類、天然繊維、及び合成繊維、半合成繊維類と天然繊維類との混合繊維からなる繊維製品に抗菌性等を付与する抗菌剤、さらに、その抗菌剤を用いた繊維製品の抗菌加工方法に関する。 The present invention relates to an antibacterial agent that imparts antibacterial properties to textile products made of synthetic fibers such as polyester fibers, semi-synthetic fibers such as acetate fibers, natural fibers, and blends of synthetic fibers, semi-synthetic fibers, and natural fibers, and further to a method for antibacterial treatment of textile products using the antibacterial agent.
特に、本発明は、結合剤を使用することなく、繊維製品に耐久性のある黄色ブドウ球菌、肺炎桿菌等に対する抗菌性を付与する繊維類の高圧加工処理用抗菌剤及び繊維類の高圧抗菌加工方法に関する。 In particular, the present invention relates to an antibacterial agent for high-pressure processing of textiles that imparts durable antibacterial properties to textile products against Staphylococcus aureus, Klebsiella pneumoniae, etc. without using a binder, and a method for high-pressure antibacterial processing of textiles.
近年、医療施設で使用される白衣、シーツ等に限らず、靴下、下着等の衣料用繊維製品、カーテン、タオル、カーペット等の身のまわりの繊維製品に、抗菌加工された繊維が使用されるようになってきている。しかし、抗菌加工では、通常、抗菌効果の持続性を高めるために、結合剤で処理することが一般的に行われている。また、繊維製品の場合、抗菌加工だけでなく、多くは難燃化、染色等の他の加工処理も行われるのが通常であり、その場合には他の処理との関係で加工条件、加工順序等色々な制約を受けることも多いのが現状である。
しかし、上述の結合剤による処理は、繊維の風合いを損ねたり、抗菌性能の低下といった問題が生じることがあり、その改善が求められている。また、抗菌加工以外の処理をそれぞれ別工程で行うことは作業工程上好ましいことではなく、いくつかの処理を同時に行うこと、例えば、染色と抗菌加工などを同時に行うことが可能な加工方法も強く望まれている。
さらに、繊維製品は洗濯をすることが前提となるため、抗菌加工では結合剤での処理によらず、耐洗濯性を備えることも要求されている。
In recent years, antibacterial fibers have come to be used not only in white coats and sheets used in medical facilities, but also in textile products for clothing such as socks and underwear, and textile products for daily use such as curtains, towels, and carpets. However, in antibacterial processing, a binder is generally used to increase the durability of the antibacterial effect. In addition, in the case of textile products, in addition to antibacterial processing, other processing such as flame retardancy and dyeing is usually also performed, and in such cases, various restrictions such as processing conditions and processing order are often imposed in relation to other processing.
However, the above-mentioned treatment with the binder can cause problems such as impairing the texture of the fiber and reducing the antibacterial performance, and improvements in these areas are required. In addition, performing treatments other than antibacterial treatment in separate steps is not preferable in terms of the work process, and there is a strong demand for a processing method that allows several treatments to be performed simultaneously, for example, dyeing and antibacterial treatment to be performed simultaneously.
Furthermore, since textile products are assumed to be washed, antibacterial finishing is required to provide washability regardless of treatment with a binder.
合成繊維等からなる製品の抗菌加工技術としては、その紡糸原液に抗菌剤を練り込み、紡糸して抗菌特性を有する繊維を使用する方法、普通に紡糸された合成、半合成繊維又はそれらを縫製して得た製品に抗菌剤を結合剤と共に付着させる方法が代表的なものである。本発明の高圧加工処理用抗菌剤は、他の抗菌剤とは異なり、結合剤を用いずに繊維に強固に付着可能であり、また、染色浴で染料と共存することができ、繊維又は繊維製品に対し、染色と同時に抗菌剤を付着させることも可能であるため、染色同浴加工に有利に使用することができる。 Representative antibacterial processing techniques for products made of synthetic fibers include a method in which an antibacterial agent is kneaded into the spinning dope and spun to use fibers with antibacterial properties, and a method in which an antibacterial agent is attached together with a binder to normally spun synthetic or semi-synthetic fibers or products obtained by sewing them. Unlike other antibacterial agents, the antibacterial agent for high-pressure processing of the present invention can be firmly attached to fibers without the use of a binder, and can also coexist with dyes in a dye bath, making it possible to attach the antibacterial agent to fibers or textile products at the same time as dyeing, and therefore can be advantageously used in dye-in-the-bath processing.
結合剤を用いずに繊維類に強固に付着でき、また、染色同浴加工に使用可能な抗菌剤としては、現時点では、特許文献１に記載されているピリチオン亜鉛が唯一実用可能なものとして知られている。また、そのピリチオン亜鉛を用いた加工方法には、繊維や繊維製品を抗菌剤を含む染色浴に浸漬し加圧下に保持する方法、繊維や繊維製品に抗菌剤を含む処理液を含浸させ次いで加熱する方法等が、特許文献１で提案されている。 At present, the only antibacterial agent known to be practical that can be firmly attached to fibers without the use of a binder and can be used in dye-in-the-same-bath processing is pyrithione zinc, described in Patent Document 1. Patent Document 1 also proposes processing methods using pyrithione zinc, such as a method in which fibers or textile products are immersed in a dye bath containing the antibacterial agent and held under pressure, and a method in which fibers or textile products are impregnated with a treatment solution containing the antibacterial agent and then heated.
しかし、上記特許文献１で使用する抗菌剤は、その化学構造中に亜鉛金属イオンを含むものであるため、製造工程や抗菌加工処理時には厳密なｐＨ管理も必要であり、また、鉄
や銅成分が存在する環境下ではその抗菌剤を製造することも、使用することもできないという問題点がある。さらに、同様の理由から、染色同浴加工に用いる場合は使用できる染料に制限がある。
また、上記特許文献１の抗菌剤は、染色同浴加工に用いた場合、耐光堅牢度などの染色性能に悪影響を及ぼすこともあり、抗菌性能と共に染色性能も改善することができ、さらに、染色同浴加工にも使用できる抗菌剤の開発が繊維加工の分野で強く求められている現状である。
However, the antibacterial agent used in the above-mentioned Patent Document 1 contains zinc metal ions in its chemical structure, so strict pH control is required during the manufacturing process and antibacterial processing, and the antibacterial agent cannot be manufactured or used in an environment where iron or copper components are present. For the same reason, there are limitations on the dyes that can be used when used in the same-bath dyeing process.
In addition, when the antibacterial agent of Patent Document 1 is used in a simultaneous dyeing bath process, it may adversely affect dyeing performance such as light fastness. Therefore, there is a strong demand in the field of textile processing for the development of an antibacterial agent that can improve dyeing performance as well as antibacterial performance and that can be used in a simultaneous dyeing bath process.
以上のとおり、繊維加工分野で使用する抗菌剤には、単に一般的な抗菌性能だけでなく、繊維評価技術協議会で規定する特定制菌加工、耐洗濯性、更には染色が必要な場合に染色同浴加工にも使用でき、染色性能にも悪影響を与えない新しい染色・抗菌加工技術の開発が待たれている。 As mentioned above, antibacterial agents used in the textile processing field do not just have general antibacterial properties, but also have specific antibacterial properties as specified by the Textile Evaluation Technology Council, washing resistance, and can even be used in dye-in-the-bath processing when dyeing is required, and new dyeing and antibacterial processing technologies are eagerly awaited, without adversely affecting dyeing performance.
本発明者等は、結合剤を用いることなく耐久性のある抗菌性能を維持でき、また、染色同浴加工にも使用できる抗菌剤及び抗菌加工方法について精力的に研究を行い、これらの研究の中から、極めて有効な高圧加工処理用抗菌剤及び高圧抗菌加工方法を見出し、本発明の完成に至ったものである。
本発明は、主に、合成繊維類を主体とする繊維類に対し、結合剤を用いることなく、黄色ブドウ球菌等に対して強い抗菌性能を持続でき、耐洗濯性を付与できる繊維類の高圧加工処理用抗菌剤及び繊維類の抗菌加工方法を提供することを目的とするものである。さらに本発明の抗菌剤は、染色同浴加工にも使用できるものである。
The present inventors have actively researched antibacterial agents and antibacterial processing methods which can maintain durable antibacterial performance without using a binder and which can also be used in dye-same-bath processing. From this research, they have discovered an extremely effective antibacterial agent for high-pressure processing and a high-pressure antibacterial processing method, which have led to the completion of the present invention.
The present invention aims to provide an antibacterial agent for high-pressure processing of fibers, which can maintain strong antibacterial activity against Staphylococcus aureus and the like and can impart washability to fibers, mainly composed of synthetic fibers, without using a binder, and an antibacterial processing method for fibers. Furthermore, the antibacterial agent of the present invention can also be used in dye-and-same-bath processing.

以下、本発明を詳細に説明する。 The present invention is described in detail below.

本発明で使用する高圧加工処理用抗菌・抗カビ剤としては、オキソリニック酸又はその塩が用いられる。
Examples of the fiber form include thread, knitted fabric, woven fabric and cloth, and examples of the products include clothing, bedding, rugs, curtains, indoor wall coverings, towels, dish towels and the like.
As the antibacterial and antifungal agent for high pressure processing used in the present invention, oxolinic acid or a salt thereof is used.
本発明において用いられるオキソリニック酸は、化学名が５-エチル-５，８-ジヒドロ-８-オキソ［１，３］ジオキソロ［４，５-ｇ］キノリン-７-カルボン酸であり、The Pesticide Manual第１０版(British Crop Protection Council発行) 、第７６０頁に記載の抗菌性化合物であり、本発明においては抗菌活性を有するオキソリニック酸だけでなく、その任意の塩、例えば、カルシウム塩、マグネシウム塩等のアルカリ土類金属塩、亜鉛塩、アルミニウム塩などの二価以上の金属塩の形でも使用される。 The oxolinic acid used in the present invention has the chemical name 5-ethyl-5,8-dihydro-8-oxo[1,3]dioxolo[4,5-g]quinoline-7-carboxylic acid, and is an antibacterial compound described in The Pesticide Manual, 10th Edition (published by the British Crop Protection Council), page 760. In the present invention, not only oxolinic acid having antibacterial activity is used, but also any salt thereof, for example, alkaline earth metal salts such as calcium salts and magnesium salts, and divalent or higher metal salts such as zinc salts and aluminum salts, are used.
オキソリニック酸は、キノリン骨格を有する抗菌剤（殺菌剤）であり、農薬としても使用されている化合物である。また、獣医学領域では、キノロン系抗生物質の一つとして利用され、安全性の評価も実施されている。
本発明のオキソリニック酸又はその塩の平均粒径は、取り扱い性や分散性の観点から０．１～１０ミクロンであることが好ましい。
Oxolinic acid is an antibacterial agent (fungicide) with a quinoline structure, and is also used as an agricultural chemical. It is also used as one of the quinolone antibiotics in veterinary medicine, and its safety is being evaluated.
The average particle size of the oxolinic acid or salt thereof of the present invention is preferably 0.1 to 10 microns from the viewpoint of handling and dispersibility.
本発明による繊維類の抗菌加工処理は加圧下に処理を行うものであり、耐圧密閉容器中に、被加工繊維重量に対し、高圧加工処理用抗菌剤０．０１～１０重量％程度、好ましくは０．１～５重量％になるようにオキソリニック酸又はその塩を入れ、これに繊維類を浸し、４０～２００℃で加熱処理することが好ましく、より好ましくは６０～１５０℃である。処理時間は通常、１０～６０分間程度である。また、加圧条件は、常圧程度の１０１３ｈＰａから４８００ｈＰａ程度以下の範囲であることが好ましい。オキソリニック酸又はその塩の濃度、処理温度、処理時間が上記範囲であれば、繊維類に対し十分な抗菌性能を付与することができる。染色同浴加工処理の場合は、処理液中の染料濃度は、０．０１～１０重量％程度である。 The antibacterial treatment of textiles according to the present invention is carried out under pressure. In a pressure-resistant sealed container, oxolinic acid or its salt is placed so that the antibacterial agent for high-pressure treatment is about 0.01 to 10% by weight, preferably 0.1 to 5% by weight, based on the weight of the textile to be processed. The textiles are then immersed in the mixture and heat-treated at 40 to 200°C, more preferably 60 to 150°C. The treatment time is usually about 10 to 60 minutes. The pressure conditions are preferably in the range of about normal pressure, 1013 hPa to about 4800 hPa or less. If the concentration of oxolinic acid or its salt, the treatment temperature, and the treatment time are within the above ranges, sufficient antibacterial properties can be imparted to the textiles. In the case of dye-and-same-bath treatment, the dye concentration in the treatment solution is about 0.01 to 10% by weight.
上記のオキソリニック酸又はその塩を分散液として使用する場合は、分散液は取り扱いの安定性等からオキソリニック酸又はその塩の濃度を１０～８０重量％としておき、実際に繊維加工に用いる場合は、用途目的に応じ、適当に希釈して用いる。通常は浴中では加工液中のオキソリニック酸又はその塩が被加工繊維重量に対し０．０１～１０重量％程度の濃度になるように希釈して用いるのが良い。 When the above oxolinic acid or its salt is used as a dispersion liquid, the concentration of oxolinic acid or its salt is set to 10 to 80% by weight for reasons of handling stability, etc., and when actually used for textile processing, it is diluted appropriately depending on the intended use. It is usually best to dilute the oxolinic acid or its salt in the processing solution in the bath so that the concentration is about 0.01 to 10% by weight relative to the weight of the fiber being processed.
前記の処理方法において処理後、さらに、熱処理を行うことにより、耐洗濯性、即ち、洗濯による抗菌性の劣化防止効力を高めることができる。この熱処理は、通常、繊維を１１０～２００℃、好ましくは１００～１５０℃で０．５～３分間程度、保持することにより行われる。 After the above-mentioned treatment, further heat treatment can be performed to improve wash resistance, i.e., the ability to prevent deterioration of antibacterial properties due to washing. This heat treatment is usually performed by holding the fibers at 110 to 200°C, preferably 100 to 150°C, for about 0.5 to 3 minutes.
繊維類の抗菌加工は繊維の種類によって条件が多少変わるが、ポリエステル繊維の場合は加圧下、１１０～１４０℃程度の温度で、トリアセテート繊維の場合は常圧下、６０～１００℃程度の温度で処理することが望ましい。いずれの場合も処理時間は１０分から１時間程度でよい。 The conditions for antibacterial treatment of textiles vary slightly depending on the type of textile, but for polyester textiles, treatment should be carried out under pressure at a temperature of about 110-140°C, and for triacetate textiles, treatment should be carried out at normal pressure at a temperature of about 60-100°C. In either case, treatment time should be around 10 minutes to 1 hour.
このようにすることにより、本発明のオキソリニック酸又はその塩は、良好に繊維類の
繊維分子間に入り込み旨く固定され、抗菌性能の持続性が向上する。
In this manner, the oxolinic acid or a salt thereof of the present invention is well embedded between the fiber molecules of the fibers and fixed thereto, improving the durability of the antibacterial activity.
