Description

本発明は、洗濯耐久性を有する抗菌抗カビ性布帛に関するものである。 The present invention relates to an antibacterial and antifungal fabric that has washing durability.

従来、医療施設や介護施設は高い衛生レベルが求められており、院内感染対策が必須である。このような施設への入所者は健常者より比較的免疫力が低く、健常者では病原性を発揮しない病原体が、免疫が低下した人に病原性を発揮する日和見感染症の危険性がある。そのため、MRSA(メチシリン耐性黄色ブドウ球菌)等の薬剤耐性菌、緑膿菌、セラチア、肺炎桿菌、エンテロバクター等のグラム陰性桿菌、クロコウジカビ(アスペルギルス)、アオカビ(ペニシリウム)、クロカビ(クラドスポリウム)、白癬菌(トリコフィトン)、カンジダ等の真菌が施設内で想定以上に繁殖し、入所者に晒されることを防ぐ必要がある。そのため、現場で使用する設備や製品は抗菌性や抗カビ性を有することもしくは、定常的な洗浄や汚染時の応急的な洗浄を容易に行えることが求められている。 Traditionally, medical facilities and nursing care facilities have been required to maintain a high level of hygiene, and measures to prevent nosocomial infections are essential. Residents of such facilities have relatively lower immunity than healthy individuals, and there is a risk of opportunistic infections in which pathogens that are not pathogenic in healthy individuals become pathogenic in immunocompromised individuals. Therefore, drug-resistant bacteria such as MRSA (methicillin-resistant Staphylococcus aureus), Gram-negative rods such as Pseudomonas aeruginosa, Serratia, Klebsiella pneumoniae, and Enterobacter, Aspergillus niger, Penicillium mold, and Cladosporium niger It is necessary to prevent fungi such as Trichophyton, Trichophyton, and Candida from multiplying more than expected within the facility and exposing residents. Therefore, equipment and products used in the field are required to have antibacterial and antifungal properties, or to be able to be easily cleaned on a regular basis or in emergencies in the event of contamination.

例えば、特許文献1では抗菌性および抗カビ性を有するポリエステル繊維が提案されている。ゼオライトに銀や亜鉛が担持された無機系抗菌剤を含むマスターバッチを作製し、ポリエステル樹脂と溶融混錬して紡糸することで得られる繊維は、表層部における無機系抗菌剤粒子の存在個数が、中心部における無機系抗菌剤粒子の存在個数の1.5倍以上であり、含有率が1~4重量%となることを特徴としており、抗カビ性能の耐久性に優れた繊維を得ることができる。しかしながら、上述の製造方法は、黄色ブドウ球菌と肺炎桿菌に対する抗菌性評価ならびに、白癬菌に対する抗カビ性評価であり、その他の菌種への対応が求められている。また、紡糸段階で抗菌剤の添加量を確定させているため、要求性能や生産数量、コストに合わせたカスタマイズは困難であるとともに、抗菌剤粒子の含有量が多いために風合いが硬くなってしまう。施設向けの衣服やカバー材等に用いた際に風合いが硬いと、肌への物理的刺激が強くなってしまうことで使用者がストレスを感じやすくなり、商品性は大きく損なわれる。さらに、カーテンのようなインテリア製品では適当なドレープ性が求められており、風合いが硬くなってしまうと柔軟性が損なわれ、製品として成り立たない。 For example, Patent Document 1 proposes polyester fibers having antibacterial and antifungal properties. A masterbatch containing an inorganic antibacterial agent with silver or zinc supported on zeolite is prepared, and the fiber obtained by melt-kneading it with a polyester resin and spinning it has a number of inorganic antibacterial agent particles in the surface layer. , the number of inorganic antibacterial agent particles present in the center is 1.5 times or more, and the content is 1 to 4% by weight, and the fiber has excellent anti-fungal performance and durability. Can be done. However, the above-mentioned production method evaluates antibacterial properties against Staphylococcus aureus and Klebsiella pneumoniae, as well as antifungal properties against Trichophyton, and is required to be applicable to other bacterial species. Additionally, since the amount of antibacterial agent added is determined at the spinning stage, it is difficult to customize the product to meet required performance, production volume, and cost, and the high content of antibacterial particles results in a hard texture. . If the texture is hard when used for clothing or covering materials for facilities, the physical irritation to the skin will be strong, making the user more likely to feel stress, and the product quality will be greatly impaired. Furthermore, interior products such as curtains are required to have appropriate drape properties, and if the texture becomes stiff, flexibility will be lost and the product will not be viable.

特許文献2では、洗濯10回後に黄色ブドウ球菌、大腸菌、モラクセラ菌に対する抗菌性を有する撥水布帛の提案がされている。しかしながら、撥水性を有するため、下着やシーツ等の吸水性が必要とされる製品には適用できず、用途が限定されてしまう。 Patent Document 2 proposes a water-repellent fabric that has antibacterial properties against Staphylococcus aureus, Escherichia coli, and Moraxella after 10 washes. However, because it has water repellency, it cannot be applied to products that require water absorption, such as underwear and sheets, and its uses are limited.

また、特許文献3では、抗菌抗カビ加工用の分散液の濃度調整、粒子径制御、異物混入を抑えることで、繊維類の洗濯耐久性と粒子の安定性、着色防止を両立する抗菌抗カビ性を施す技術が提案されている。しかしながら、アオカビや白癬菌、MRSA等には対応しているものの、湿気が多い所で特に繁殖するクロカビには対応していない。また、分散液濃度の調整で繊維に対する機能性付与を狙っているが、繊維素材や織編組織によって機能剤の付着量は大きく異なるため、生地の種類によっては機能性を十分に発揮できないおそれがある。
このように、現状において、洗濯耐久性が優れ、医療・介護施設内で特に注意されるMRSAやクロカビ、アオカビ、クロコウジカビ等の幅広い菌に対して強い抗菌性ならびに抗カビ性を示す、抗菌抗カビ性布帛の開発が待たれている。
In addition, Patent Document 3 describes an antibacterial and antifungal treatment that achieves washing durability of textiles, particle stability, and coloration prevention by adjusting the concentration of a dispersion liquid for antibacterial and antifungal processing, controlling particle size, and suppressing the contamination of foreign substances. Techniques for applying sex have been proposed. However, although it is compatible with green mold, tinea fungus, and MRSA, it is not compatible with black mold, which especially grows in humid places. In addition, we aim to impart functionality to fibers by adjusting the concentration of the dispersion liquid, but since the amount of functional agent attached varies greatly depending on the fiber material and weaving structure, there is a risk that the functionality may not be fully demonstrated depending on the type of fabric. be.
As described above, currently there are antibacterial and antifungal products that have excellent washing durability and exhibit strong antibacterial and antifungal properties against a wide range of bacteria such as MRSA, black mold, blue mold, and Aspergillus niger, which are of particular concern in medical and nursing care facilities. The development of mold-resistant fabrics is awaited.

本発明は、上記問題点に鑑みてなされたものであり、MRSAやクロカビ、アオカビ、クロコウジカビ等の幅広い菌に対して強い抗菌性ならびに抗カビ性を示し、柔軟性および洗濯耐久性等の耐久性に優れた抗菌抗カビ性布帛を提供することを目的とする。 The present invention was made in view of the above problems, and exhibits strong antibacterial and antifungal properties against a wide range of bacteria such as MRSA, black mold, black mold, and Aspergillus black mold, and has excellent durability such as flexibility and washing durability. The purpose of the present invention is to provide an antibacterial and antifungal fabric with excellent properties.

本発明は、ポリエステル繊維を含有する抗菌抗カビ性を有する布帛であって、抗菌抗カビ成分が、前記ポリエステル繊維に分散された状態で付着しており、前記抗菌抗カビ成分の固形物が、前記ポリエステル繊維の表面の0.01mmあたりに20~300個存在するように付着している抗菌抗カビ性布帛である。 The present invention is a fabric having antibacterial and antifungal properties containing polyester fibers, in which an antibacterial and antifungal component is attached to the polyester fiber in a dispersed state, and the solid substance of the antibacterial and antifungal component is It is an antibacterial and antifungal fabric that is attached to the surface of the polyester fiber in an amount of 20 to 300 pieces per 0.01 mm 2 .

また、洗濯50回後の前記抗菌抗カビ成分の固形物が、0.01mmあたりに3個以上であることが好ましい。 Further, it is preferable that the number of solids of the antibacterial and antifungal component after 50 washes is 3 or more per 0.01 mm 2 .

また、前記抗菌抗カビ成分が有機系薬剤であると好ましい。 Further, it is preferable that the antibacterial and antifungal component is an organic drug.

本発明によれば、MRSAやアオカビ、クロカビ等の幅広い菌に対して強い抗菌性ならびに抗カビ性を示し、柔軟性および洗濯耐久性等の耐久性に優れた抗菌抗カビ性布帛を提供することができる。 According to the present invention, there is provided an antibacterial and antifungal fabric that exhibits strong antibacterial and antifungal properties against a wide range of bacteria such as MRSA, blue mold, and black mold, and has excellent durability such as flexibility and washing durability. Can be done.

本発明の一実施形態にかかる抗菌抗カビ成分が付着しているポリエステル繊維の模式図である。FIG. 1 is a schematic diagram of polyester fibers to which an antibacterial and antifungal component is attached according to an embodiment of the present invention.

以下、本発明の抗菌抗カビ性布帛について説明する。ただし、本発明は、以下に説明する実施形態に記載される構成に限定されることを意図しない。 The antibacterial and antifungal fabric of the present invention will be explained below. However, the present invention is not intended to be limited to the configurations described in the embodiments described below.

本発明の抗菌抗カビ性布帛は、ポリエステル繊維を含有し、抗菌抗カビ成分が、前記ポリエステル繊維に分散された状態で付着しており、前記抗菌抗カビ成分の固形物が、前記ポリエステル繊維の表面の0.01mmあたりに20~300個存在するように付着している。なお、本発明における分散された状態とは、図1に示すように、ポリエステル繊維1の全体にわたって抗菌抗カビ成分2が存在し、抗菌抗カビ成分2が繊維断面の外周部だけでなく繊維内部にも繊維の全体に存在することをいう。また、抗菌抗カビ成分2´のように固形物が隣接していても、偏在せずに繊維断面の外周部ならびに中心付近を含む繊維内部にほぼ均等に存在していれば、分散した状態という。 The antibacterial and antifungal fabric of the present invention contains polyester fibers, and the antibacterial and antifungal component is attached to the polyester fiber in a dispersed state, and the solid substance of the antibacterial and antifungal component is attached to the polyester fiber. 20 to 300 particles are attached to each 0.01 mm 2 of the surface. In addition, as shown in FIG. 1, the dispersed state in the present invention means that the antibacterial and antifungal component 2 is present throughout the polyester fiber 1, and the antibacterial and antifungal component 2 is present not only on the outer periphery of the fiber cross section but also inside the fiber. It also means that it is present throughout the fiber. In addition, even if the solids are adjacent to each other like the antibacterial and antifungal ingredient 2', if they are not unevenly distributed and exist almost evenly inside the fiber, including the outer periphery and center area of the fiber cross section, it is said to be in a dispersed state. .

抗菌抗カビ成分2が、前記ポリエステル繊維に分散された状態で付着しており、かつ、繊維表面に付着している抗菌抗カビ成分の固形物が0.01mmあたりに20~300個存在している。固形物が20個以上であれば、洗濯50回後の抗菌性ならびに抗カビ性に優れ、好ましくは、30個以上であり、より好ましくは、40個以上である。固形物が300個以下であれば、柔軟性に優れ、好ましくは、250個以下であり、より好ましくは、200個以下である。固形物が20個未満であると、洗濯50回後における抗菌抗カビ成分の含有量が抗菌性ならびに抗カビ性を発揮するのに不足してしまい、目的とする抗菌性ならびに抗カビ性を得ることができない。また、固形物が300個を超えると、柔軟性を損なうとともに、繊維上に付着する成分が過剰となることで洗濯時の脱落量が増加してしまい、使用量に対する洗濯耐久性向上の効率が悪くなる。また、成分が過剰なため、洗濯時に脱落する成分が多くなり、同浴で洗濯する他繊維製品への汚染を引き起こすおそれが高くなる。なお、抗菌抗カビ成分の個数を計測する際には、走査型電子顕微鏡による元素マッピングで観察し、抗菌抗カビ成分の粒径が1μm以上の固形物を計測する。抗菌抗カビ成分は、粒径が1~50μmの固形物であると好ましいが、1μm未満の固形物や50μmを超える固形物が存在しても構わない。 The antibacterial and antifungal component 2 is attached to the polyester fiber in a dispersed state, and there are 20 to 300 solid particles of the antibacterial and antifungal component attached to the fiber surface per 0.01 mm2 . ing. If the number of solids is 20 or more, the antibacterial and antifungal properties after 50 washes are excellent, and the number is preferably 30 or more, more preferably 40 or more. If the number of solid particles is 300 or less, the flexibility is excellent, and the number is preferably 250 or less, more preferably 200 or less. If the number of solids is less than 20, the content of the antibacterial and antifungal component after 50 washings will be insufficient to exhibit antibacterial and antifungal properties, and the desired antibacterial and antifungal properties will be achieved. I can't. Furthermore, if the number of solids exceeds 300, the flexibility will be impaired and the amount of components that will adhere to the fibers will be excessive, resulting in an increase in the amount of shedding during washing, and the efficiency of improving washing durability relative to the amount used will be reduced. Deteriorate. Furthermore, since the amount of components is excessive, more components will fall off during washing, increasing the risk of contaminating other textile products washed in the same bath. In addition, when counting the number of antibacterial and antifungal components, observation is performed using elemental mapping using a scanning electron microscope, and solid substances having a particle size of 1 μm or more of the antibacterial and antifungal components are measured. The antibacterial and antifungal component is preferably a solid substance with a particle size of 1 to 50 μm, but solid particles less than 1 μm or larger than 50 μm may be present.

繊維内部に存在している抗菌抗カビ成分は、ポリエステル繊維に分散した状態で付着していることが重要である。もし、繊維外周部に抗菌抗カビ成分が凝集し、繊維中心部に存在する抗菌抗カビ成分が少ないと、洗濯によって成分が脱落してしまい、洗濯50回後における抗菌性ならびに抗カビ性を得ることができない。繊維中心部に抗菌抗カビ成分が集まり、外周部に存在しない状態では、洗濯による脱落は抑えられるが、抗菌抗カビ成分が繊維表面に付着した菌と接触することがほとんどできないため、抗菌性ならびに抗カビ性を得ることができない。 It is important that the antibacterial and antifungal components present inside the fibers be attached to the polyester fibers in a dispersed state. If the antibacterial and antifungal components aggregate on the outer periphery of the fibers and the amount of antibacterial and antifungal components present in the center of the fibers is small, the components will fall off during washing, resulting in no antibacterial and antifungal properties after 50 washes. I can't. If the antibacterial and antifungal ingredients gather in the center of the fiber and are not present on the outer periphery, they will be prevented from falling off when washed, but since the antibacterial and antifungal ingredients will hardly come into contact with bacteria attached to the fiber surface, the antibacterial and antibacterial properties will be reduced. Antifungal properties cannot be obtained.

繊維に付着した抗菌抗カビ成分の含有量が、0.02~6.0g/mであると好ましい。0.02g/m以上であれば、洗濯50回後の抗菌性ならびに抗カビ性に優れ、より好ましくは、0.04g/m以上であり、さらに好ましくは、0.06g/m以上である。6.0g/m以下であれば、洗濯50回後の抗菌性ならびに抗カビ性と柔軟性がともに優れ、より好ましくは、5.0g/m以下であり、さらに好ましくは、4.0g/m以下である。布帛に対して洗濯処理を行うと、抗菌抗カビ成分の一部が脱落すると考えられるが、0.02g/m未満であると、洗濯50回後における抗菌抗カビ成分の含有量が抗菌性ならびに抗カビ性を発揮するのに不足してしまい、抗菌性ならびに抗カビ性を得にくくなる。また、6.0g/mを超えると、柔軟性を損なうとともに、繊維表面に付着する抗菌抗カビ成分が過剰となることで洗濯時の脱落量が増加してしまい、使用量に対する洗濯耐久性向上の効率が悪くなる。また、抗菌抗カビ成分が過剰なため、洗濯時に脱落する成分が多くなり、同浴で洗濯する他繊維製品への汚染を引き起こすおそれが高くなる。 The content of the antibacterial and antifungal component attached to the fibers is preferably 0.02 to 6.0 g/m 2 . If it is 0.02 g/m 2 or more, it has excellent antibacterial and antifungal properties after 50 washings, more preferably 0.04 g/m 2 or more, and even more preferably 0.06 g/m 2 or more. It is. When it is 6.0 g/m 2 or less, both antibacterial and antifungal properties and flexibility after 50 washings are excellent, and it is more preferably 5.0 g/m 2 or less, and even more preferably 4.0 g. / m2 or less. It is thought that some of the antibacterial and antifungal components fall off when the fabric is washed, but if it is less than 0.02 g/m 2 , the content of the antibacterial and antifungal components after 50 washes is considered to be antibacterial. Also, it is insufficient to exhibit antifungal properties, making it difficult to obtain antibacterial and antifungal properties. In addition, if it exceeds 6.0 g/ m2 , flexibility will be impaired and the amount of antibacterial and antifungal components that adhere to the fiber surface will be excessive, resulting in an increase in the amount of shedding during washing, resulting in poor washing durability for the amount used. Improvement efficiency becomes worse. In addition, because the antibacterial and antifungal components are excessive, more components fall off during washing, increasing the risk of contaminating other textile products washed in the same bath.

本発明に使用されるポリエステル繊維は、布帛中に50重量%以上含まれることが好ましく、60重量%以上含まれることがより好ましく、70重量%以上含まれることが更に好ましい。ポリエステル繊維が50重量%以上含まれていれば、抗菌抗カビ成分を効率よく、ポリエステル繊維に付着させることができ、洗濯後の抗菌性ならびに抗カビ性および生地強度を向上させることができる。 The polyester fiber used in the present invention is preferably contained in the fabric in an amount of 50% by weight or more, more preferably 60% by weight or more, and even more preferably 70% by weight or more. If the polyester fiber is contained in an amount of 50% by weight or more, the antibacterial and antifungal component can be efficiently attached to the polyester fiber, and the antibacterial and antifungal properties and fabric strength after washing can be improved.

ポリエステル繊維としては、特に限定するものではなく、ポリエチレンテレフタレート(PET)、ポリトリメチレンテレフタレート(PTT)、ポリブチレンテレフタレート(PBT)、ポリエチレンナフタレート(PEN)、ポリブチレンナフタレート(PBN)、カチオン可染ポリエステル、ポリ乳酸等が挙げられ、これらの中から1種または2種以上を組み合わせて使用することができる。 Polyester fibers are not particularly limited, and include polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN), polybutylene naphthalate (PBN), and cationic fibers.

Examples include organic drugs, and one type or a combination of two or more types thereof can be used. Among these, organic drugs are preferable because they exhibit antibacterial and antifungal properties more quickly than inorganic drugs and can be used against a wide range of bacteria, and pyridine compounds are more preferable. In particular, 2-pyridylthiol-1-oxide metal salt is more preferred because it has good affinity and adhesion to fibers, is excellent in durability, and is compatible with a wide range of bacterial species.

ポリエステル繊維には染料を含有していても含有していなくてもよいが、繊維外周部には染料を含有しないことが堅牢度の面で好ましい。染料としては、具体的に分散染料、カチオン染料、反応染料、酸性染料、直接染料が挙げられ、これらの中から1種または2種以上を組み合わせて使用することができる。 The polyester fiber may or may not contain a dye, but it is preferable from the viewpoint of fastness that the outer periphery of the fiber does not contain a dye. Specific examples of the dye include disperse dyes, cationic dyes, reactive dyes, acid dyes, and direct dyes, and one or more of these may be used in combination.

抗菌抗カビ成分をポリエステル繊維に含有させた布帛を得る際には、繊維加工において一般的に行われている方法を用いればよく、例えば、(1)抗菌抗カビ成分を含む処理液に布帛を浸漬し、常圧下もしくは加圧下80~140℃の浴中で吸尽処理する方法、(2)抗菌抗カビ成分を含む処理液に布帛を浸漬、またはスプレーもしくは塗布することにより、処理液を繊維布帛に含浸させた後、必要に応じて圧搾や遠心脱水等で余剰液を除去し、次いで80~180℃で熱処理して乾燥する方法を挙げることができる。なかでも、繊維内部まで抗菌抗カビ成分を浸透させ、繊維表面にも適度で均一な付着状態とすることが可能であることから、(1)の吸尽処理する方法を0.1~3kg/cm(ゲージ圧)の範囲の加圧下で行うことが好ましい。 When obtaining a fabric containing polyester fibers containing an antibacterial and antifungal component, it is sufficient to use a method commonly used in textile processing. (2) soaking, spraying or coating the fabric in a treatment solution containing antibacterial and antifungal components; applying the treatment solution to the fibers; After the fabric is impregnated, excess liquid is removed by squeezing or centrifugal dehydration as necessary, and then heat treatment is performed at 80 to 180°C to dry. Among them, the exhaustion treatment method (1) is used because it allows the antibacterial and antifungal ingredients to penetrate into the inside of the fibers and to achieve a moderate and uniform adhesion state on the fiber surface. It is preferable to carry out under pressure in the range of cm 2 (gauge pressure).

なお、抗菌抗カビ成分を含む処理液は、本発明の目的を阻害しない程度であれば、必要に応じて、染料、各種染色助剤、黄変防止剤、制電剤、吸水剤、撥水剤、防虫剤、難燃剤、柔軟剤、pH調整剤等、他の成分を含んでいてもよく、特に限定されない。 The treatment liquid containing antibacterial and antifungal components may contain dyes, various dyeing aids, anti-yellowing agents, antistatic agents, water absorbing agents, and water repellents as necessary, as long as they do not impede the purpose of the present invention.

実施例1~7および比較例1~4で得られた抗菌抗カビ性布帛について、先述の評価方法で評価した結果を表1に示した。 Table 1 shows the results of evaluating the antibacterial and antifungal fabrics obtained in Examples 1 to 7 and Comparative Examples 1 to 4 using the evaluation method described above.

Figure 2024000337000002
Figure 2024000337000002

実施例1~7の抗菌抗カビ性布帛は、洗濯前および洗濯50回後における抗菌性ならびに抗カビ性、生地強度、柔軟性のいずれも優れていた。 The antibacterial and antifungal fabrics of Examples 1 to 7 were excellent in both antibacterial and antifungal properties, fabric strength, and flexibility before and after washing 50 times.

一方、比較例1の抗菌抗カビ性布帛は、ポリエステル繊維の全体に占める割合が低いため、十分な強度とならなかったとともに、抗菌抗カビ成分の含有が不十分であったため、抗菌性ならびに抗カビ性は低いものとなった。さらに、比較例2ならびに4の抗菌抗カビ性布帛では、抗菌抗カビ成分が過剰に付着していたため、柔軟性が損なわれてしまった。また、比較例3の抗菌抗カビ性布帛では、抗菌抗カビ成分が十分に付着していないため、洗濯後の抗菌性ならびに抗カビ性は得られなかった。 On the other hand, the antibacterial and antifungal fabric of Comparative Example 1 did not have sufficient strength because the proportion of polyester fibers in the total amount was low, and the antibacterial and antifungal component was insufficient. Mildew property was low. Furthermore, in the antibacterial and antifungal fabrics of Comparative Examples 2 and 4, the antibacterial and antifungal component was excessively adhered to the fabrics, resulting in loss of flexibility. In addition, in the antibacterial and antifungal fabric of Comparative Example 3, the antibacterial and antifungal components were not sufficiently attached, so that antibacterial and antifungal properties could not be obtained after washing.
