Abstract

A layered disinfecting fabric comprising a first activated carbon layer and a bonded second layer, wherein the second layer contains a metal coating, wherein the second layer is porous, wherein the metal coating is between 10nm and 20micrometer in average thickness. The slow release of metal from the second layer will result in the spreading of metal or metal ions over the carbon area, resulting unlike for each materials separately in a very strong disinfecting effect.

Description

消毒織物結構sanitizing fabric structure

本發明係有關一種消毒織物結構。The present invention relates to a disinfecting fabric structure.

隨著Covid-19大流行，抗病毒及消毒紡織品及織物變得無處不在，特別係應用於面罩，如Livingard®面罩及由Heiq Viroblock®塗層織物製成的面罩。此類織物的常見類型含有金屬或金屬氧化物之粉末或奈米顆粒，諸如銀奈米顆粒或氧化銅。雖然已知許多金屬及金屬氧化物具有消毒效果，但此等材料之功效係有限的。此外，金屬氧化物、金屬顆粒或奈米顆粒的釋放可為潛在的健康及環境問題，因為此等物質對生物體及環境均有毒（https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7177798）。With the Covid-19 pandemic, antiviral and antiseptic textiles and fabrics are becoming ubiquitous, especially for face masks such as Livingard® masks and those made of Heiq Viroblock® coated fabrics. Common types of such fabrics contain powders or nanoparticles of metals or metal oxides, such as silver nanoparticles or copper oxide. Although many metals and metal oxides are known to have disinfecting effects, the efficacy of these materials is limited. Furthermore, the release of metal oxides, metal particles or nanoparticles can be a potential health and environmental concern as these substances are toxic to organisms and the environment (https://www.ncbi.nlm.nih.gov/pmc /articles/PMC7177798).

某種化合物之消毒功效取決於其與病毒或微生物物質相互作用的表面。例如，將一層厚厚的污染物暴露於平坦的抗病毒表面可能僅破壞與抗病毒表面直接接觸的物質部分。出於此原因，當在具有大有效表面積的材料（如高度多孔的活性碳（活性碳））上擴散時或在溶液中時，例如當自紡織品釋放至水滴或水霧中時，抗病毒化合物更有效。通常，然後需要在紡織品上大量溶解或釋放消毒化合物（金屬、金屬氧化物、金屬顆粒等）以獲得可觀的消毒效果。The disinfection efficacy of a compound depends on the surface on which it interacts with viral or microbial material. For example, exposing a thick layer of contaminants to a flat antiviral surface may damage only the portion of the material that is in direct contact with the antiviral surface. For this reason, antiviral compounds are more effective when diffused on materials with a large effective surface area, such as highly porous activated carbon (activated carbon), or when in solution, for example when released from textiles into water droplets or mist. efficient. Usually, then large quantities of disinfecting compounds (metals, metal oxides, metal particles, etc.) need to be dissolved or released on the textiles to obtain appreciable disinfection effects.

特別地，當前的抗病毒紡織品標準ISO18184量測了紡織品與接種病毒之間相互作用兩小時後剩餘的活化病毒，原濃度為每毫升約十的七次方（1e7）個病毒。蘇黎世韋登斯維爾（Wädenswil, Zurich）的蘇黎世應用科技大學（Zurich University of Applied Sciences；ZHAW）在Chahan Yeretzian教授的監督下進行的測試表明，Livingard®及Viroblock®等最先進的商業面料在更嚴格的測試中表現出非常差的效能，該等測試使用較短持續時間及/或較高病毒濃度及健壯/強健的病毒類型（MS2噬菌體）。In particular, the current standard for antiviral textiles, ISO18184, measures the remaining activated virus after two hours of interaction between the textile and the inoculated virus, at an original concentration of approximately ten to the seventh power (1e7) viruses per milliliter. Tests at the Zurich University of Applied Sciences (ZHAW) in Wädenswil, Zurich under the supervision of Prof. Chahan Yeretzian have shown that state-of-the-art commercial fabrics such as Livingard® and showed very poor performance in tests using shorter durations and/or higher virus concentrations and robust/robust virus types (MS2 phage).

顯然，當暴露於病毒或微生物污染時，防護面罩儘可能快地發揮作用將為有利的，即使在持續供應病毒之情況下，亦能保持面罩中之活病毒或細菌濃度較低。Clearly, when exposed to viral or microbial contamination, it would be advantageous for a protective mask to function as quickly as possible, keeping the concentration of live virus or bacteria in the mask low even with a constant supply of virus.

同時，活性碳為一種以吸收及捕獲化學物質以及病毒及微生物而聞名的材料。材料之實例包括來自經碳化以產生高有效表面積的嫘縈、聚苯胺或基諾爾（kynol）的紡織品或非織物。或者，可將直徑為10-50微米之活性碳顆粒固定在用於織物的紡織品中，如德國公司Blücher所做的一樣。一種技術包括與如苯乙烯-丁二烯橡膠或PVDF之類的黏合劑混合，藉由例如刀式塗佈機將塗層施加至紡織品上，且固化。此類糊劑例如用於製造用於水脫鹽之電容去離子中使用的電極，例如Voltea公司所用。其他技術包括將碳顆粒固定在紡織品層或非織物層或膜層之間。除了捕獲病毒及微生物外，碳纖維織物在破壞/不活化病毒及微生物方面表現出低至中等的功效。Meanwhile, activated carbon is a material known for absorbing and trapping chemicals as well as viruses and microbes. Examples of materials include textiles or non-wovens from rayon, polyaniline or kynol that have been carbonized to create a high effective surface area. Alternatively, activated carbon particles with a diameter of 10-50 microns can be immobilized in textiles for fabrics, as done by the German company Blücher. One technique involves mixing with a binder such as styrene-butadiene rubber or PVDF, applying the coating to the textile by eg a knife coater, and curing. Such pastes are used, for example, for the manufacture of electrodes used in capacitive deionization for water desalination, as used by the company Voltea for example. Other techniques include immobilizing carbon particles between textile or non-woven layers or film layers. In addition to trapping viruses and microorganisms, carbon fiber fabrics showed low to moderate efficacy in destroying/inactivating viruses and microorganisms.

本發明基於一種認識，亦即活性碳之高表面積可提供薄薄地擴散金屬或金屬離子所需的表面，從而獲得以下優點： •    與目前最先進的抗病毒及抗菌織物及紡織品相比，消毒效果顯著提高。 •    對環境及生物友好——不含金屬氧化物、奈米顆粒或其他可能被環境或生物體吸收的顆粒或高度可溶解的物質。 The present invention is based on the recognition that the high surface area of activated carbon provides the surface required for thin diffusion of metals or metal ions, resulting in the following advantages: • Compared with the most advanced antiviral and antibacterial fabrics and textiles, the disinfection effect is significantly improved. • Environmentally and biologically friendly - does not contain metal oxides, nanoparticles or other particles or highly soluble substances that may be absorbed by the environment or organisms.

活性碳層亦提供了能夠捕獲病毒及微生物的優勢。因此，本發明提供了一種有效的「捕獲及不活化」材料。例如應用於面罩，含有病毒之霧氣會被碳層吸收，若病毒將被捕獲在碳表面上且因同一表面上的金屬或金屬離子的存在而不活化。The activated carbon layer also offers the advantage of being able to trap viruses and microbes. Thus, the present invention provides an effective "trap and inactivate" material. For example applied to a face mask, the mist containing virus will be absorbed by the carbon layer, if the virus will be trapped on the carbon surface and not activated due to the presence of metal or metal ions on the same surface.

本發明提供如申請專利範圍中所定義之分層消毒織物，及包含該織物之製品。亦提供使用該織物使微生物及病毒不活化之方法，及製備該分層消毒織物之方法。The present invention provides a layered sanitizing fabric as defined in the claims, and articles comprising the same. Also provided are methods of using the fabrics to inactivate microorganisms and viruses, and methods of making the layered disinfecting fabrics.

因此，根據本發明，在碳層之一側添加第二織物層（在替代實施例中，在碳層之兩側添加此類層），其含有金屬，該金屬不作為高溶解性塗層，而是作為可藉由電鍍技術以及物理或化學氣相沈積技術獲得的連續且堅固的塗層。例如，以Statex®、Shieldex®及Xstatic®品牌提供銀塗層紗線及紡織品。儘管如此，正如所有金屬表面一樣，會有少量金屬及金屬離子釋放，此對本發明很重要。金屬塗層厚度之範圍可為0.5 nm至20微米，更典型地在50 nm與2微米之間。Therefore, according to the invention, a second fabric layer is added on one side of the carbon layer (in an alternative embodiment such layers are added on both sides of the carbon layer) containing a metal which does not act as a highly soluble coating but As a continuous and robust coating obtainable by electroplating techniques as well as physical or chemical vapor deposition techniques. For example, silver-coated yarns and textiles are offered under the Statex®, Shieldex® and Xstatic® brands. Nevertheless, as with all metal surfaces, there will be small amounts of metal and metal ion release that are important to the present invention. The metal coating thickness can range from 0.5 nm to 20 microns, more typically between 50 nm and 2 microns.

本發明利用活性碳提供表面之能力，在該表面上可捕獲來自固體及塗層金屬表面之非常少量的金屬或金屬離子釋放物，從而提供具有捕獲及不活化病毒及微生物物質的高表面積。The present invention utilizes the ability of activated carbon to provide a surface on which very small amounts of metal or metal ion releases from solid and coated metal surfaces can be captured, thereby providing a high surface area with which to capture and deactivate viral and microbial material.

典型的金屬包括銀及銅。替代金屬包括金、鐵、鈦、鉬、鈷、鎳、錫及其他金屬。銀作為金屬尤其較佳。Typical metals include silver and copper. Alternative metals include gold, iron, titanium, molybdenum, cobalt, nickel, tin, and others. Silver is especially preferred as metal.

在一個態樣中，提供一種分層消毒織物，其包含： 第一層，其中該第一層由活性碳製成，及 第二層，其中該第二層含有金屬組分； 其中該第二層為多孔層， 其中該第二層與該第一層直接接觸，且 其中該第二層含有作為平均厚度在0.5奈米與20微米之間的塗層的金屬。 In one aspect, there is provided a layered sanitizing fabric comprising: a first layer, wherein the first layer is made of activated carbon, and a second layer, wherein the second layer contains a metallic component; Wherein the second layer is a porous layer, wherein the second layer is in direct contact with the first layer, and Wherein the second layer contains the metal as a coating having an average thickness between 0.5 nm and 20 microns.

本發明之織物可包含以下層或由以下層組成： •    由例如碳化聚丙烯腈織物（或者碳化基諾爾/酚醛纖維（novoloid）或嫘縈或其他織物）製成的活性碳織物，基重可能在30與400 g/m 2之間； •    基於銀塗層紗線之紡織品，其中紗線上銀之塗層厚度可為0.5至1.5微米，且成品塗層紡織品的基重可在約30與250 g/m 2之間； •    層可用高度多孔的聚醯胺網膠層壓在一起，或縫合在一起，例如藉由縫合方形網格圖案，其中網格尺寸可在0.5 cm至10 cm之間； •    視情況，可在碳層與含銀層之間施加額外的多孔層或紡織品，只要其不完全阻止活性碳織物與基於銀塗層紗線之紡織品之間的接觸即可。 The fabrics of the present invention may comprise or consist of the following layers: • Activated carbon fabrics made of, for example, carbonized polyacrylonitrile fabrics (or carbonized kenoll/novoloid or rayon or other fabrics), basis weights may Between 30 and 400 g/ m2 ; • Textiles based on silver-coated yarns, where the thickness of the silver coating on the yarn can be from 0.5 to 1.5 microns and the basis weight of the finished coated textile can be between about 30 and 250 g/ m2 ; • layers can be laminated together with highly porous polyamide mesh glue, or sewn together, for example by sewing a square grid pattern, where the grid size can be between 0.5 cm and 10 cm ; • Optionally, an additional porous layer or textile can be applied between the carbon layer and the silver-containing layer, as long as it does not completely prevent contact between the activated carbon fabric and the textile based on silver-coated yarns.

本發明結構中之第一層可為活性碳布（ACC）或活性碳紡織品，其為織物或非織物。其可藉由嫘縈、基諾爾/酚醛纖維、聚丙烯腈或其他纖維製成的前驅紡織品或非織物的碳化製成。或者，其可由固定在諸如聚偏二氟乙烯（PVDF）或苯乙烯-丁二烯橡膠之黏合劑中的活性碳顆粒或纖維製成。或者，第一層可包含固定在紡織品或非織物中之活性碳顆粒，在此類紡織品或非織物層之間，或藉由使用膠或黏合劑將活性碳顆粒固定至非織物或紡織品纖維上。第一層之基重可在30與400 g/m 2之間。 The first layer in the structure of the present invention can be activated carbon cloth (ACC) or activated carbon textile, which is woven or non-woven. It can be made by carbonization of precursor textiles or non-wovens made of rayon, kenore/phenolic fibers, polyacrylonitrile or other fibers. Alternatively, it can be made of activated carbon particles or fibers fixed in a binder such as polyvinylidene fluoride (PVDF) or styrene-butadiene rubber. Alternatively, the first layer may comprise activated carbon particles immobilized in the textile or non-woven, between such textile or non-woven layers, or by immobilizing the activated carbon particles to the non-woven or textile fibers using glue or adhesives . The basis weight of the first layer may be between 30 and 400 g/m 2 .

在應用於面罩時，活性碳層及含金屬紡織品層可沿面罩周邊處或附近的線縫合在一起。相反，此等層亦可沿著其一部分或整個表面層壓在一起。When applied to a mask, the layers of activated carbon and metal-containing textile may be stitched together along threads at or near the perimeter of the mask. Conversely, the layers can also be laminated together along a portion or the entire surface thereof.

在另一個實施例中，平均厚度在0.5奈米與20微米之間的金屬塗層直接施加至活性碳層之至少一側，而不存在於單獨的紡織品層上。In another embodiment, a metallic coating having an average thickness between 0.5 nanometers and 20 micrometers is applied directly to at least one side of the activated carbon layer without being present on a separate textile layer.

當例如在面罩中使用時，病毒或細菌可能會隨著空氣流嵌入霧中而進入面罩中。碳層將有效地捕獲病毒或細菌，而吸附在碳表面之金屬或金屬離子會使其不活化。When used, for example, in a mask, viruses or bacteria may enter the mask with the air flow embedded in the mist. The carbon layer will effectively trap viruses or bacteria, while the metals or metal ions adsorbed on the carbon surface will deactivate them.

為了提供金屬或金屬離子自含金屬織物至活性碳表面之初始轉移，根據本發明之分層織物可浸泡在水或另一溶劑中或者經水或另一溶劑潤濕，然後作為製造程序的一部分進行乾燥。在織物之使用壽命期間，該程序可重複一或多次以便維持其消毒劑特性。In order to provide initial transfer of metal or metal ions from the metal-containing fabric to the activated carbon surface, the layered fabric according to the present invention may be soaked or wetted with water or another solvent before as part of the manufacturing process to dry. This procedure can be repeated one or more times during the useful life of the fabric in order to maintain its disinfectant properties.

可使用熱熔膠、網狀膠、再活化膠或紡織工業中可用的其他技術將活性碳及金屬塗層織物層層壓在一起。任何層壓應使得活性碳層與含金屬層之間的一些接觸區域得到維持。或者，此等層可縫合在一起。The activated carbon and metal coated fabric layers can be laminated together using hot melt adhesives, reticulated adhesives, reactivated adhesives or other techniques available in the textile industry. Any lamination should be such that some contact area between the activated carbon layer and the metal-containing layer is maintained. Alternatively, the layers can be stitched together.

含金屬織物可以單獨由金屬塗層紗線（Statex、Xstatic或類似物）或與習知合成或天然紗線組合製成。或者，金屬塗層可以作為後處理施加在習知紡織品上。在一個實施例中，金屬將直接塗佈在活性碳層上，從而在碳的頂部提供多孔層。可使用濺射塗層、物理氣相沈積或化學氣相沈積或電鍍方法將金屬施加至紗線、習知紡織品層或活性碳層的頂部。或者，織物可由大塊金屬紗線或含金屬紗線與基於合成或天然纖維之紗線的混合物組成。第二層之基重可在約30與250 g/m 2之間。 Metallic fabrics can be made from metal coated yarns (Statex, Xstatic or similar) alone or in combination with conventional synthetic or natural yarns. Alternatively, the metallic coating can be applied on conventional textiles as a post-treatment. In one embodiment, the metal will be coated directly on the activated carbon layer, providing a porous layer on top of the carbon. The metal can be applied on top of the yarn, conventional textile layer or activated carbon layer using sputter coating, physical or chemical vapor deposition or electroplating methods. Alternatively, the fabric may consist of bulk metallic yarns or a mixture of metallic yarns and synthetic or natural fiber based yarns. The basis weight of the second layer may be between about 30 and 250 g/ m2 .

在一個實施例中，第二層由含有藉由氣相沈積或電鍍技術塗佈有金屬之紗線的紡織品組成。在另一實施例中，第二層由藉由氣相沈積或電鍍技術直接沈積在第一層上的金屬層組成。In one embodiment, the second layer consists of a textile containing yarns coated with metal by vapor deposition or electroplating techniques. In another embodiment, the second layer consists of a metal layer deposited directly on the first layer by vapor deposition or electroplating techniques.

消毒紡織物之潛在應用包括傷口敷料及其他醫療應用，諸如手術室及醫療機構的防護服、手術單及其他表面紡織品，例如窗簾或床單。較佳用途為用於面罩。消毒紡織品可用於攜帶型應用，如袋子的襯裡。此外，消毒紡織品可應用於傢俱及作為工作場所、公共建築、公共交通、租車等的室內紡織品。Potential applications for antiseptic textiles include wound dressings and other medical applications such as protective clothing for operating theaters and healthcare institutions, surgical drapes and other surface textiles such as curtains or bed sheets. The preferred use is for face masks. Sterilized textiles can be used in portable applications such as linings for bags. In addition, sanitized textiles can be applied in furniture and as interior textiles in workplaces, public buildings, public transport, rental cars, etc.

測試結果 本節介紹的實驗室測試由位於瑞士韋登斯維爾的蘇黎世應用科技大學（ZHAW）在教授Chahan Yeretzian博士的監督下進行且報告。 Test Results The laboratory tests presented in this section were carried out and reported at the Zurich University of Applied Sciences (ZHAW) in Weidenswil, Switzerland under the supervision of Prof. Dr. Chahan Yeretzian.

測試方法 大腸桿菌屬（ Escherichia）病毒MS2用作一種模式病原體：一種感染細菌大腸桿菌（ Escherichia Coli）且與冠狀病毒屬於同一分類界的病毒。 Test method Escherichia virus MS2 was used as a model pathogen: a virus that infects the bacterium Escherichia Coli and belongs to the same taxonomic kingdom as coronaviruses.

程序：使用霧化器用再蒸餾水潤濕紡織品之片。然後藉由在其表面上點上新鮮的MS2病毒懸浮液來接種紡織品層壓材料[3][4]。參考測試使用棉紡織品進行（根據ISO 105-F02）。每個實驗至少一式三份進行，且對於每個實驗，驗證所使用的病毒原液（=接種物）的濃度。然後藉由沖洗程序回收病毒，此係藉由在沖洗溶液（SCDLP培養基，根據ISO 18184）中對紡織品進行消化或渦旋。然後將所得液體的系列稀釋液與軟瓊脂及大腸桿菌混合且倒入瓊脂平板上。孵育後，對噬菌體（病毒）噬菌斑進行計數，且計算不活化率。Procedure: Moisten the textile sheet with redistilled water using an atomizer. The textile laminate was then inoculated by spotting a fresh MS2 virus suspension on its surface [3][4]. Reference tests were performed with cotton textiles (according to ISO 105-F02). Each experiment was performed at least in triplicate and for each experiment the concentration of the virus stock (= inoculum) used was verified. Viruses were then recovered by a washing procedure by digesting or vortexing the textiles in a washing solution (SCDLP medium according to ISO 18184). Serial dilutions of the resulting liquid were then mixed with soft agar and E. coli and poured onto agar plates. After incubation, the phage (viral) plaques were counted and the inactivation rate was calculated.

除非另有說明，否則不確定性係指95%信賴區間。該方法對低活化度不太準確，部分原因係必須手動計數大量噬菌斑（活病毒）。Uncertainties refer to 95% confidence intervals unless otherwise stated. The method is less accurate for low activation, in part because large numbers of plaques (live virus) must be manually counted.

活性碳紡織品之抗病毒效果測試測試了重量為110 g/m 2之標準商業活性碳紡織品。該織物由聚丙烯腈碳化製成。 Antiviral Effect Test of Activated Carbon Textiles Standard commercial activated carbon textiles with a weight of 110 g/ m2 were tested. The fabric is made of carbonized polyacrylonitrile.

量測到病毒去活化度30%±45%。此為一個非常差的去活化。實驗資料如下。 表1 結果：平均值 樣本 平均值 母體標準差 變異係數（COV）[%] 相對0.95信賴區間（CI）[%] 接種物 1.46E+09 4.1E+07 3% 4% 活性碳紡織品 1.03E+09 2.7E+08 26% 65% 棉對照 1.30E+09 3.0E+08 23% 207% 表2 結果 x0 （對照） x1 （處理） Log無菌 平均不活化% ±95% CI（理論） 接種物 活性碳紡織品 0.2 30 ±45 表3 描述 活性碳紡織品 重複 次數 3 樣本面積 9.5 cm×9.5 cm 預潤濕 每側12次噴霧 潤濕重量： 濕 [g]- 乾 [g]= 水 [ml] 50.61 - 48.11 = 2.50 ml 50.41 - 48.21 = 2.20 ml 50.18 - 48.08 = 2.10 ml 預滅菌 無 處理時間 120分鐘 The virus inactivation degree was measured to be 30%±45%.

同一研究所後來的測試報告了甚至更高的消毒程度，超過了99%。Later tests by the same institute reported an even higher degree of disinfection, exceeding 99%.

與目前市場上的消毒紡織品比較：ZHAW測試了市場上兩種常見的抗病毒紡織面罩中使用的織物。 Comparison with antiseptic textiles currently on the market: ZHAW tested the fabrics used in two common antiviral textile face masks on the market.
