Description

多功能布及多功能罩
本發明關於多功能布及多功能罩，具體而言，關於可抗菌、抗病毒、阻擋PM2.5污染物且透氣之多功能布及多功能罩。
紡織品之種類繁多，包括植物纖維、動物纖維、合成纖維等，具有各種不同的特性，可以適應不同季節之穿著需求，但是其無法同時具有抗病毒及防PM2.5污染物滲入之特性。不織布之成本低廉，可作為建築、醫療器材、居家用品等之材料，具有廣泛之用途。不織布具有透氣、柔軟、易栽縫、耐折疊、絕緣、防雨、防漏、堅韌、抗菌、衛生、吸水性強等特性，但是也無法同時具有抗病毒及防PM2.5污染物滲入之特性。
罩包括口罩、鼻罩、面罩等，基本功能為阻隔污染物進入人體。口罩、鼻罩及面罩覆蓋在臉部之面積大小不同，但其基本結構大致相同，故在此僅以口罩來說明。目前市面上的口罩大致上可分為：活性碳口罩、醫療口罩、棉布口罩、紙口罩、PM2.5口罩、N95口罩及抗病毒抗菌口罩，但不管是哪一種口罩，均無法同時具有優良的抗病毒及抗菌、防污水滲入、防PM2.5污染物滲入且透氣良好、配戴舒適之功能。
本發明之目的，在於提供一種同時具有抗菌、抗病毒及防止PM2.5污染物滲入之多功能布及多功能罩之結構。本發明採用聚四氟乙烯（PTFE，polytetrafluoroethylene）膜、以及包括奈米複合材料之活性層之積層結構，藉由PTFE膜之材料特性而具有更高的透氣性以及過濾PM2.5污染物之能力，同時藉由包括奈米複合材料之活性層之材料特性而達到抗病毒、抗菌、分解有機污染物之能力。
在一態樣中，本發明提出一種多功能布，包括至少一PTFE層及至少一活性層。PTFE層由聚四氟乙烯（PTFE）所構成。活性層位於PTFE層之第一側。活性層包括載體及形成於載體上之奈米複合材料，奈米複合材料可用於抗菌、抗病毒及分解有機物。
PTFE層及活性層其中一者或兩者之表面可為鋸齒狀或具有皺折。或者，PTFE層及活性層之表面可為平面。在某些實施例中，PTFE層與活性層之外可包括額外的一或更多PTFE層及∕或一或更多活性層。
活性層之載體可為織布。或者，活性層之載體可為不織布。活性層中之奈米複合材料可包括，例如，奈米銀及奈米二氧化鈦。
本發明之多功能布亦可包括潑水層，潑水層由潑水布所構成。在一實施例中，潑水層位於PTFE層之第二側，PTFE層之第二側為第一側之相反側，使得PTFE層位於潑水層與活性層之間。在另一實施例中，潑水層位於PTFE層之第一側，使得活性層位於潑水層與PTFE層之間。
在另一態樣中，本發明提出一種多功能罩，包括上述的多功能布及親膚層，親膚層可用於吸附油脂或汗水。在一實施例中，親膚層位於PTFE層之第一側，使得活性層位於親膚層與PTFE層之間。在另一實施例中，親膚層位於PTFE層之第二側，使得PTFE層位於親膚層與活性層之間。
以下將參考圖式以進一步說明這些及其它態樣。
本發明之目的、優點和特色由以下數個實施例之詳細說明及伴隨的圖式當可更加明白。應當了解，圖中所示之各種實施例是示意性的，且不一定按照比例繪製。
圖1顯示本發明之多功能布10，其具有高透氣性，並且具有抗病毒、抗菌、分解有機物以及防止PM2.5污染物滲入之特性。多功能布10包括PTFE層12及活性層14，活性層14位於PTFE層12之一側。在圖1所示之實施例中，活性層14位於PTFE層12之第一側120。
PTFE層12是以聚四氟乙烯（PTFE）為原料，利用PTFE之成孔特性，經特別工法壓延、擠出、雙向拉伸而製成微孔性膜層。PTFE層具有原纖維狀微孔結構，孔隙率約為80%以上，每平方公分具有約十億個以上的微孔，孔徑範圍約為0.02微米至3微米。微孔性PTFE膜層具有網狀（例如，蜘蛛網狀）的微孔結構，孔隙形成於微纖維之間，微纖維之排列方向與拉伸方向基本上是平行的。微纖維束之連接處即為結點，其是由許多微纖維糾纏相連而形成。PTFE膜屬於非對稱性膜，膜之正反面微孔尺寸有差異。PTFE膜之截面之微孔尺寸大於表面之微孔尺寸，且縱橫向之微孔尺寸也有差異，例如，縱向微孔尺寸可大於橫向微孔尺寸。PTFE膜是一種三維（3D）網狀結構，其中之孔隙在三維上為網狀連通，使得孔道彎曲且互相交錯，因而形成綿密的通道。
在一範例中，在PTFE層12之表面，每平方公分具有十多億個微孔，每一微孔之直徑（0.1 μm-0.5 μm）比水分子直徑（20 μm-100 μm）小幾百倍，但比水蒸氣分子直徑（0.0003 μm-0.0004 μm）大上萬倍，使得水蒸氣能通過PTFE層，而水滴不能通過。因此，本發明使用PTFE層做為多功能布內部結構之一部分，可阻隔PM2.5污染物，但又可達到絕佳的透氣效果。
活性層14包括載體及形成於載體上之奈米複合材料。活性層14中之載體可為不織布。或者，活性層14中之載體可為較耐洗滌之織布。此外，活性層14中之奈米複合材料可用於抗菌、抗病毒及分解有機污染物。在一範例中，可採用奈米銀複合奈米二氧化鈦溶膠，以噴塗法、浸漬塗佈法或其它合適的方法，使包括奈米銀及奈米二氧化鈦之奈米複合材料附著於布上，因而製備出本發明之活性層14。例如，奈米銀之顆粒大小可為約0.1 nm至約60 nm，奈米二氧化鈦之顆粒大小可為約0.1 nm至約60 nm。奈米複合材料在載體上之厚度可為，例如，小於1 mm。活性層14中之奈米複合材料可與細菌及病毒反應，以降低細菌及病毒之活性、甚至將其殺死。奈米複合材料亦可與有機物（例如，有機污染物）反應而將其分解。在一些實施例中，由久造實業有限公司所販售之商品「奈米新型複合材料TTA系列」（例如，JM-TTA01）為合適的奈米複合材料之範例。
在一實施例中，PTFE層12及活性層14兩者之表面可為平面，如圖1所示。在其它實施例中，PTFE層12及活性層14其中一者或兩者之表面可為鋸齒狀或具有皺折，以增加PTFE層及∕或活性層之表面積，使其對於細菌、病毒、空污等之阻隔、抵抗、分解效果更佳。例如，PTFE層12及活性層14其中一者可為鋸齒狀或具有皺折，如圖2(a)及圖2(b)所示。或者，PTFE層12及活性層14兩者之表面皆為鋸齒狀或具有皺折，如圖2(c)所示。
根據需要，本發明之多功能布可包括複數PTFE層、複數活性層、或其組合。例如，在某些實施例中，可在圖1之PTFE層12與活性層14之外加入額外的一或更多PTFE層及∕或一或更多活性層，該等層可以任何排列方式加以組合。
本發明之多功能布可更包括潑水層。如圖3所示，多功能布30包括撥水層16、PTFE層12及活性層14，潑水層16由潑水布所構成。在圖3所示之實施例中，活性層14位於PTFE層12之第一側120，潑水層16位於PTFE層12之第二側122（第二側122為第一側120之相反側），使得PTFE層12位於潑水層16與活性層14之間。在其它實施例中，潑水層可位於PTFE層之第一側，使得活性層位於潑水層與PTFE層之間。如上所述，PTFE層12及活性層14其中一者或兩者之表面可為鋸齒狀或具有皺折。在其它實施例中，多功能布30可包括複數PTFE層、複數活性層、或其組合；該等層可以任何排列方式加以組合。
在另一態樣中，利用上述的多功能布再加上親膚層，形成一種多功能罩，可做為口罩、鼻罩、面罩等，但不限於此。在使用多功能罩時，親膚層會與使用者之皮膚接觸，可用於吸附油脂或汗水，並且達到配戴舒適之效果。如圖4所示，多功能罩40包括PTFE層12、活性層14及親膚層18。在圖4所示之實施例中，親膚層18位於PTFE層12之第一側120，使得活性層14位於親膚層18與PTFE層12之間。在另一實施例中，親膚層可位於PTFE層之第二側，使得PTFE層位於親膚層與活性層之間。如上所述，PTFE層12及活性層14其中一者或兩者之表面可為鋸齒狀或具有皺折。在其它實施例中，多功能罩40可包括複數PTFE層、複數活性層、或其組合；該等層可以任何排列方式加以組合。
本發明之多功能罩可更包括潑水層。如圖5所示，多功能罩50包括撥水層16、PTFE層12、活性層14及親膚層18。在圖5所示之實施例中， PTFE層12位於撥水層16與活性層14之間，且活性層14位於PTFE層12與親膚層18之間。在其它實施例中，可將圖5中之PTFE層與活性層之位置互換，使得活性層位於撥水層與PTFE層之間，且PTFE層位於活性層與親膚層之間。PTFE層12及活性層14其中一者或兩者之表面可為鋸齒狀或具有皺折。在其它實施例中，多功能罩50可包括複數PTFE層、複數活性層、或其組合；該等層可以任何排列方式加以組合。
如圖6所示，在一實施例中，多功能罩60包括撥水層16、PTFE層12、二活性層14及14’、及親膚層18。多功能罩60具有兩層活性層14及14’，包覆在PTFE層12之兩側，可更加提升其抗病毒、抗菌及分解有機物之效果。
以上說明了多功能布及多功能罩之示例性結構組成，其可利用各種合適的技術進行製作。在一例子中，可採用高週波熱融合技術來使各層結合。例如，可在高週波設備中設置複數個點狀熱源，點狀熱源可排列成矩陣型式、或任何其它合適的型式。將各層依需要而堆疊成多層體之後，置於高週波設備下方，將高週波設備通電而使點狀熱源升溫，點狀熱源便可將各層在複數個對應位置處予以融合相接，而製作成本發明之多功能布或多功能罩。如圖7所示，多功能布70可利用十字形的點狀熱源來使各層接合，因此具有呈十字形的接合點702。但點狀熱源亦可具有其它形狀，例如線形、圓形、方形等。在其它例子中，可採用機器或人工縫合、膠貼合、或其它合適的技術來使各層接合。
本發明中之活性層包括奈米複合材料。在一例子中，奈米複合材料包括奈米銀及奈米二氧化鈦。奈米銀本身具有高抗病毒抗菌效果；而二氧化鈦是一種光觸媒，在日光燈、太陽光或紫外光燈之照射下，二氧化鈦具有高活性可以氧化分解有機污染物。因此，在奈米銀抗病毒抗菌過程後，即使有殘餘生物膜附着在奈米銀表面，但二氧化鈦可以將殘餘生物膜分解去除，使奈米銀可以再次發揮抗病毒抗菌之效果。此外，奈米二氧化鈦具有超強的親水性，不會因為被口水沾濕而失效，反而可以將水分解為氫氧自由基（OH·），該氫氧自由基（OH·）具有超強的氧化能力，可以氧化分解有機物，使病毒病菌失去活性。
本發明中之活性層包括奈米複合材料，其效果優於未奈米化的複合材料。例如，奈米銀之抗病毒抗菌效果遠大於未奈米化的銀粒子，而奈米二氧化鈦之活性亦遠大於未奈米化的二氧化鈦。
當將具有小孔徑之PTFE膜與具有奈米複合材料之活性層結合使用時，發明人發現，抗菌、抗病毒及防止PM2.5污染物滲入之效果出奇的好，且同時依然維持良好的透氣性。推測可能是由於PTFE膜之微孔不只能阻隔液態水分子及PM2.5污染物，同時也減緩了細菌、病毒、微生物等穿透之速度，讓活性層中之奈米複合材料有充裕的時間可以與細菌、病毒、微生物進行反應，以降低或消除其活性。因此，本發明之多功能布及多功能罩具有非常優異的功效。但應當注意，其運作不限於上述機制。
儘管上述實施例已為了清楚理解之目的而詳細地加以描述，但在所附申請專利範圍之範疇中，可進行某些變更及修改。因此，本案之實施例應被視為是用於說明之目的，而非用於限制本發明之範圍。
