Description

紡織材料上的氣味降低及細菌控制
本發明係關於用於紡織材料上的氣味降低及細菌控制之組合物及方法，更具體而言使用公認安全(Generally-Recognized-as-Safe, GRAS)抗微生物/防腐添加劑或組分(例如食品防腐劑)用於紡織材料上的氣味降低及細菌控制之組合物及方法。
當前紡織服裝上的細菌控制在很大程度上依賴於使用含金屬之活性物質，例如銀或鋅。該等化學物質降低對洗滌之耐久性，可導致織物變色，且不易於併入大多數紡織品製造製程中。另外，紡織廠之製程出水中「重金屬」之存在一直係管理者及政策制定者關注之問題。
另一選擇，可利用有機分子(例如，四級銨矽烷、酚類及唑類)之使用來處理紡織品表面。該等化學物質需要大量配方設計工作以降低疏水性，增加耐久性，且其僅適用於紡織品壓吸應用。
迄今為止，唯一可應用於大多數紡織品製造製程中而沒有技術問題之化學物質係吡啶硫酮鋅。然而，此獨特化學物質正接受管理機構之審查。該等審查最終可導致無法利用吡啶硫酮鋅降低紡織品表面上的導致氣味及著色之細菌。
因此，現行技術不能進行吸盡及壓吸，對紡織品性質具有不利影響，且被分類為可能的毒素。因此，迫切需要獲得新解決方案以控制紡織品表面上的氣味及細菌。
因此，業內需要對紡織品有微生物及氣味控制效能之替代化學物質，該等替代化學物質有效、安全、環境友好、易於應用於當前紡織廠技術且使用價格實惠。
本發明係關於用於紡織材料上的氣味降低及細菌控制之組合物，該組合物使用具有抗微生物或防腐性質之公認安全(GRAS)添加劑或組分。GRAS添加劑之實例尤其包括(但不限於)最低風險農藥、食品防腐劑。

相關申請案之交叉參考
此申請案主張對2019年12月30日申請之美國臨時專利申請案第62/955,161號及2019年12月30日申請之美國臨時專利申請案第62/955,155號及2020年12月21日申請之美國專利申請案第17/128,849號在美國專利商標局(United States Patent and Trademark Office)中之優先權。該等之揭示內容均以其整體引用的方式併入本文中。
本發明實施例之以下描述本質上僅係實例性的，且絕不意欲限制本發明、其應用或用途。以下描述僅以實例方式提供於本文中用於提供本發明之可實施揭示內容，但並不限制本發明之範圍或實質。
本發明係關於組合物及方法，該等組合物及方法使用環境友好之成分用於賦予紡織材料之細菌及氣味控制，同時亦不損害紡織材料之染色製程。儘管本發明含有可能在紡織品染色及處理製程期間改變一些染料色彩之活性成分，但本發明亦含有在紡織品染色及處理製程期間同時保護染料分子免於改變之額外成分。
在本發明之實施例中，提供用於賦予紡織材料之氣味降低及細菌控制之「公認安全」(GRAS)之組合物。縮寫字「GRAS」係由聯邦管理機構使用，以指根據優良藥品製造規範在使用時認為係「公認安全」之物質。舉例而言，該等法規包括21 CFR 182、21 CFR 184及21 CFR 186。
GRAS組分或化合物之實例包括(但不限於)食品防腐劑。作為一類別，食品防腐劑可適用於本發明之組合物，此乃因其分類為最低風險農藥，同時提供抗微生物效能。然而，適用於本發明之任何食品防腐劑應能夠承受包括＞150℃之溫度的紡織品處理環境，且具有水可分散性、與乙酸之相容性以及低皮膚毒性概況。
在本發明之實施例中，抗微生物添加劑係有機酸。有機酸之實例包括(但不限於)苯甲酸、丙酸、山梨酸、檸檬酸、乳酸、抗壞血酸、乙酸、異抗壞血酸、富馬酸、蘋果酸、乙醇酸、其衍生物及其組合。較佳有機酸包括(但不限於)苯甲酸、山梨酸、檸檬酸及其組合。
適用於本發明之GRAS添加劑之其他實例係苯甲酸鈉及山梨酸鉀。
本發明組合物可包含一或多種添加劑。舉例而言，精油可與苯甲酸、山梨酸或其組合來組合添加以具有對抗真菌物種之活性。
精油之實例包括(但不限於)雪松木油、茶油(互葉白千層(Melaleuca alternifolia))、桉樹油(藍桉樹(Eucalyptus globulus)或狹葉桉(E. radiata))、丁香油(丁香(Eugenia caryophyllata))、牛至油(牛至(Origanum vulgare))、麝香草油(麝香草(Thymus vulgaris))、香葉油(香葉天竺葵(Pelargonium graveolens))、肉桂皮油(肉桂(Cinnamomum zeylanicum))、薄荷油(西洋薄荷(Mentha piperita))、檸檬香茅油(蜿蜒香茅(Cymbopogon flexuosus))、羅勒油(羅勒(Ocimum basilicum))、薰衣草油(狹葉薰衣草(Lavandula angustifolia))、檸檬油(檸檬(Citrus limon))、迷迭香油(迷迭香(Salvia rosmarinus))、香檸檬油(香檸檬(Citrus bergamia))、紫蘇油(紫蘇(Perilla frutescens))、芫荽油(芫荽(Coriandrum sativum))、香櫞油(枸櫞(Citrus medica))及其組合。較佳精油包括(但不限於)肉桂皮油(肉桂)、檸檬香茅油(蜿蜒香茅)、麝香草油(麝香草)、雪松木油、香茅油、薄荷油、迷迭香油、丁香油及其組合。一些精油(例如薄荷油、肉桂油)幾乎沒有抗細菌活性，但對真菌物種具有獨特影響。
另外，期望控制紡織品表面上之非微生物有關氣味。有機酸(或其組合)可提供中和基於鹼性之氣味(例如氨)之能力。此外，具有芳基之有機酸具有螯合環基臭味物質(例如吡啶)之潛力。為補充該等效應，可將額外氣味減輕化合物添加至苯甲酸、山梨酸及/或精油之組合中，以去除存在的氣味。氣味減輕化合物之添加產生可提供抗微生物及氣味控制益處之獨特摻合物。氣味減輕化合物之實例包括(但不限於)金屬氧化物、活性碳、碳酸鈉、碳酸鈣及蓖麻醇酸鋅。
金屬氧化物(例如，ZnO)至任何化學物質之添加均產生可提供抗微生物及氣味控制益處之獨特摻合物。已測試氨、醛基氣味(例如，壬醛)及鹼性氣味(例如，吡啶)並確定降低氣味位準(藉由GC量測)。除藉由控制細菌數降低細菌氣味以外，此功能將允許活性酸控制非細菌產生之氣味。
在本發明之實施例中，本發明之組合物包含苯甲酸、山梨酸或其組合之穩定懸浮液，其總濃度為以組合物之重量計5%至60%活性成分、較佳以組合物之重量計10%至50%活性成分。酸存在於載劑中，該載劑係水或可為二醇(例如丙二醇、二-丙二醇)、有機溶劑，或利用將溶解該酸並使本發明為溶液而非分散液之表面活性劑。併入抗微生物劑之再另一方法係利用酸之鹽(例如，苯甲酸之苯甲酸鈉)進行調配，將基於鹽之調配物添加至液體中，且然後將另外的酸添加至吸盡浴液中以降低浴之pH，以使苯甲酸鹽轉化為苯甲酸。由於鹽在水中之高溶解度，此將允許將濃縮物調配成易於管控之水性液體。
本發明之組合物可視情況包含以組合物之重量計1%至20%之總濃度的精油且可視情況包含以組合物之重量計1%至20%、較佳以組合物之重量計5%至10%之總濃度的金屬氧化物。
在本發明之實施例中，提供使用紡織品處理組合物、較佳GRAS紡織品處理組合物之方法。本發明之組合物可藉由熟習紡織工業之技術者已知之任何施加方法施加至紡織材料。舉例而言，兩種傳統紡織方法係吸盡及壓吸。
紡織廠利用液體工程製程(例如吸盡或壓吸)來併入輔助化學物質及整理劑(例如抗微生物劑)。由於在紡織品製造製程中需要液體組分，因此有機酸呈液體形式(穩定溶液或分散液)或在消費者使用之前分散於水中。許多有機酸不易於與水混溶。已觀察到將有機酸分散於水中時，在短時間後酸沉降而形成難以以使用者友好方式再分散之填充層。可將分散劑添加於紡織品組合物或浴以解決此問題。舉例而言，非離子分散劑可用於此目的。分散劑幫助潤濕酸表面、在個別粒子之間形成距離，並降低高負載漿液之黏度。另一非限制性分散劑之實例係可分散無機聚合物晶體，其具有在酸粒子之間起作用並為濃縮物之流變性提供觸變性質之能力。此添加劑進一步確保在消費者使用時酸粒子易於再分散。
感興趣的是，在吸盡染色製程中，苯甲酸及山梨酸與染料一起藉助PET纖維在目標操作溫度下發生之熱驅動之玻璃轉換物理變化引入PET表面及內部非晶形區。將分散染料與分散劑一起研磨。該等分散劑本質上係經解離酸官能基封端之碳鏈。經歷解離之分散劑藉助膠束作用在正確的操作溫度下攜帶染料分子進入PET纖維。一旦膠束適當地接近PET結構，凡得瓦(van der Waals)力便發揮作用且染料分子黏附至PET纖維之內部非晶形區。然後，膠束表面活性劑分子吸引不同的未結合染料分子且此製程重新開始。有機酸(例如，苯甲酸及山梨酸)經歷解離，在羥基氧上產生負電荷，且因此不需要額外分散劑。因此，有機酸具有極性且被利用染料引入之極性分散劑吸引。有機酸成為攜帶染料之膠束的一部分，並找到緊密接近PET表面及或內部非晶形區之路徑。在紡織品染色製程期間將有機酸嵌入PET纖維中防止還原清除步驟損害有機酸，且紡織材料在洗滌後仍展示效能(參見圖4)。
本發明之組合物可呈液體濃縮物之物理形式。酸必須首先以濃縮物形式分散，且然後可稀釋以用於實際應用。紡織品吸盡製程通常需要使用水作為媒劑以攜帶染料及用於織物處理之任何添加劑。
在本發明之實施例中，較佳呈聚合濃縮物形式之本發明組合物(例如，用於塗層之聚合黏合劑)包含苯甲酸、山梨酸或其組合。在聚合黏合劑中，基於溶液%固體，需要在0.1%至40%範圍內之濃度。若組合使用一種以上酸，則活性酸之總重量介於最終組合物重量之5%至60%之間、較佳最終組合物重量之5%至40%。處理組合物作為濃縮液添加至吸盡或壓吸浴中，以使最終濃度以織物重量計為0.1%至5%活性成分。舉例而言，精油(若存在)之最終濃度按織物重量計可為0.05重量%至1重量%，且氣味減輕化合物(若存在)之最終濃度按織物重量計可為0.05重量%至1重量%。
無機聚合物流變改質劑可與本發明之濃縮液一起使用以防止或減少由於有機酸之存在而對紡織品吸盡製程中所用之一些染料產生之任何不利效應。有機酸(例如苯甲酸或山梨酸)可改變染料之色調。觀察到色調變化通常係不期望的，此乃因一旦吸盡製程開始，紡織廠便無法調整染料摻合物。意外地，無機聚合物流變改質劑除緩和濃縮液之流變性質以外，亦幫助保持及穩定染料色彩。無機添加劑提供具有非離子型分散劑、有機酸及水分子之定向基質，以提供在吸盡製程中對染料較不苛刻之環境。
施用方法用於處理紡織材料，包括合成及天然衍生之纖維。
本發明之紡織品組合物在最終使用位準上係無害的，適用於大多數形式之紡織品製造，對洗滌穩定且不影響紡織品性質。所選GRAS酸在相關處理溫度下係熱穩定的，如圖2所示之熱解重量數據所示。
在染料吸盡製程之後，可將紡織織物暴露於NaOH及/或還原劑(例如，亞硫酸氫鈉)，以在稱為「還原清洗」之製程中自紡織品去除任何未反應之染料。由於理論上苯甲酸及山梨酸可在還原清洗製程期間去除，因此在還原清洗後評估具有上述任一種化學物質之紡織品，以確保其在工業製程中倖存。
在紡織品處理及染色製程期間，本發明之活性成分變為織物之纖維的一部分，在纖維中其不會因多次洗滌而被洗掉。表面活性劑、芯吸劑、均染劑、軟化劑及黏合劑之使用確保在吸盡製程期間活性成分之適當分佈及其分子定向。乳液表面活性劑幫助併入活性成分之膠束形成。芯吸劑用於在吸盡期間改良極性及非極性表面之界面。添加均染劑以確保染料在織物上之均勻分佈。染料吸盡製程中所用之紡織品黏合劑留在織物上且有助於活性成分耐久性。併入紡織品軟化劑以在使用黏合劑時使織物有較柔軟觸感。此外，所用之分散染料化學物質及表面活性劑允許形成膠束，該等膠束在正確的操作溫度下攜帶染料分子進入PET纖維。一旦膠束適當地接近PET結構，凡得瓦力便發揮作用且染料分子黏附至PET纖維之內部非晶形區。然後，膠束表面活性劑分子吸引不同的未結合染料分子且此製程重新開始。此指示，有機酸經歷離解並導致帶負電荷之離子酸吸引至膠束之親水頭，並找到緊密接近PET表面及或內部非晶形區之路徑。在紡織品染色製程期間將有機酸嵌入PET纖維中防止有機酸在重複洗滌中被洗掉，此給予抗微生物益處之耐久性。
在本發明之實施例中，提供用本發明之組合物處理之諸如紡織材料之物件。可考慮且在本發明之範圍內，可用本發明之組合物處理其他材料及物體。
比較實例
如圖1中所圖解說明，僅使用苯甲酸、山梨酸及檸檬酸中每一者之鹽(苯甲酸鈉、山梨酸鉀及檸檬酸三鈉)導致相對較低之效能位準。另外，使用鹽處理服裝表面導致紡織品在應用後觸感僵硬。用鹽處理之服裝的該兩個特徵以及以及將降低洗滌耐久性之鹽的良好水溶性使得該等不適於紡織品使用。注意，在此情形中，未試圖降低液體pH以將鹽轉化為酸。
實例1
如圖3中所圖解說明，在業內公認之方法AATCC 38之洗滌方案後，苯甲酸及山梨酸在多個洗滌循環後能夠維持效能。此係紡織工業內之典型要求。檸檬酸單獨不能與苯甲酸及山梨酸處理一樣在相同洗滌方案後維持效能。
實例2
運行實驗以證實用0.4%肉桂油處理之紡織品樣品的抗真菌性。根據工業方法AATCC 30(III)，在暴露於黑麯黴(Aspergillus niger )培養物第4天之後，將精油添加至苯甲酸或山梨酸在經處理樣品周圍導致可見之無生長區域。此獨特組合使經處理紡織材料具有抗細菌及抗真菌活性二者。
實例3
使用相同百分比之三種染料藍色、紅色及黃色(每一者與三種聚對苯二甲酸乙二酯織物樣品中之每一者組合使用)，實施紡織品染料吸盡實驗。第一織物樣品(A)僅利用染料進行吸盡。第二織物樣品(B)係利用染料及活性濃縮液進行吸盡，該活性濃縮液利用無機聚合物流變改質劑調配，其中所存在有機酸之量等於吸盡浴重量之0.5%。第三織物樣品(C)係利用染料及吸盡浴重量之0.5%之有機酸、但在沒有完整配方之濃縮液的情形下進行吸盡。浴之液比為10:1。
結果顯示，樣品(A)之色調更像第二樣品(B)之色調，且樣品(C)明顯具有不同色調。經調配濃縮液在匹配色彩方面較單獨有機酸更有效。
使用0.5% owb苯甲酸處理率來進行比色。A係無苯甲酸之未處理對照，B經於其經調配濃縮液產物中之0.5% owb苯甲酸處理，且C係在無經調配濃縮液之情形下經0.5% owb苯甲酸處理。
實例4
高染料負荷樣品係最難以使用吸盡染色技術處理之樣品。使用PET (聚酯)及聚氨綸(polyspandex)織物運行一系列測試。在此測試系列中，將材料在兩個不同實驗室中使用容器式實驗室吸盡設備進行測試。除經處理樣品外，運行未經處理之織物用於比較。吸盡製程使用以下參數：
10:1液比
12.5 g/L苯甲酸分散液，40%苯甲酸
在130℃下40分鐘之吸盡循環
5%酸分散染料 – 黑色
還原清洗 – 0.3% NaOH及0.4%亞硫酸氫鈉在85℃下20分鐘
在130℃下乾燥120s
使用AATCC TM100 -2019測試樣品之效能。Kp僅作為指標生物運行，此乃因已發現有效對抗Kp之任何樣品亦有效對抗Sa。

表1 - 兩個不同聚酯織物供應商，兩個不同位置，經處理樣品之減少百分比。織物係原樣及25次家庭洗滌(25 HL)後測試。每次家庭式洗滌均使用Tide HE洗滌劑根據AATCC Monograph M6在商用滾筒式洗衣機中進行。
表1中之結果顯示，在所有情形中平均細菌減少＞90%且在大多數情形中＜ 99%。每一數值均由使用來自不同供應商之兩種黑色染料在有或沒有染料均染劑之情形下產生之24個測試樣品組成，各組間之效能沒有顯著差異。藉由此技術證實優良洗滌耐久性。
以與上述相同之方式運行聚氨綸以及PET。對於此類似於PET、但具有額外彈性體組分(90% PET、10%氨綸)之材料，產生以下結果：

除效能測試外，亦測試該等樣品之染料色彩及堅牢度，此乃因染料色彩之品質必須不受抗微生物處理之影響。對來自以上兩個測試組之樣品以及以相同方式與經處理樣品一起產生之未經處理樣品實施以下標準紡織品品質控制測試：

自該等結果可看出，染料堅牢度及色彩與未經處理織物匹配，由此得出所提出之抗微生物處理不會影響染料堅牢度或色彩之結論。

實例 6
將有機酸(例如苯甲酸)引入水性系統(例如吸盡液)之一種可能性係藉助添加有機酸之鹽且然後將系統之pH降至低於pKa值。紡織廠通常使用乙酸或檸檬酸以控制液體pH。苯甲酸之鹽係苯甲酸鈉，且此系統之pKa值係4.2。根據Henderson- Hasselbalch方程式，若pH降至約3.6，80%添加至系統之苯甲酸鈉將轉化成苯甲酸。使用水溶性鹽並將液體酸化至3.6或以下之pH係將本發明併入吸盡液中並允許水性調配物而無需形成分散液之方便方法。表6中之結果係指示使用苯甲酸鈉並酸化液浴相當於用苯甲酸處理之實例。
表6 – 聚酯織物如上述實例4運行，惟使用檸檬酸酸化至pH ＜3.6之苯甲酸鈉代替苯甲酸以賦予抗微生物益處。經處理與未處理之染色織物樣品之間未觀察到明顯差異。
