本發明係關於一種生物纖維漿料,其可用於製備具優異吸濕率及濕強力的乾式生物纖維材料。因此,本發明亦關於一種製備乾式生物纖維材料之方法、乾式生物纖維材料、及應用該乾式生物纖維材料之護膚膜。
生物纖維是使用微生物發酵所生長的天然纖維,其直徑僅約20奈米,比人體頭髮細約1000倍。隨著發酵的進行,生物纖維可長成生物纖維膜,此為目前所知最細緻,觸感與皮膚最接近,且保水力及彈性均優異的材料,因此特別適合應用在美容及生醫領域,例如可作為面膜基材,供吸附護膚成分。
然而,生物纖維膜具有乾燥後即無法回復吸水性能的缺點,因此必須一直保持於濕潤狀態,無法如一般不織布面膜基材般製成乾式的成捲布材,這導致生物纖維膜難以連續生產,以及保存與運送上的不便。此外,生物纖維膜經裁切後會產生無法使用的廢料,目前這些廢料係直接丟棄,無法加以利用,此不僅造成浪費,也增加廢棄物處理的不便。
有鑑於前述之現況,本發明利用生物纖維廢料提供一種生物纖維漿料,該生物纖維漿料可用於製備一種新型態的乾式生物纖維材料,該乾式生物纖維材料可被連續地製造成成捲產品,便於儲存及運送,並且該乾式生物纖維材料具有優異的吸濕率及濕強力,特別適合作為護膚膜之基材。
因此,本發明之一目的在於提供一種生物纖維漿料,包含:生物纖維;結構纖維,其係選自以下群組:嫘縈纖維、聚對苯二甲酸乙二酯(polyethylene terephthalate,PET)纖維、尼龍纖維、及其組合;接著纖維,其係選自含聚乙烯複合纖維類;助黏劑,其係選自以下群組:聚醯胺類、低密度聚乙烯類、及其組合;防乾劑,其係選自多元醇類;以及分散介質。
於本發明生物纖維漿料之部分實施態樣中,結構纖維係嫘縈纖維與聚對苯二甲酸乙二酯纖維之組合,接著纖維係聚乙烯-聚酯複合纖維,助黏劑係聚醯胺,且防乾劑係甘油。
於本發明生物纖維漿料之部分實施態樣中,以100重量份之生物纖維計,結構纖維之量為4重量份至12重量份,接著纖維之量為2重量份至8重量份,且助黏劑之量為4重量份至10重量份。較佳地,以100重量份之生物纖維計,結構纖維之量為6重量份至8重量份,接著纖維之量為3重量份至5重量份,且助黏劑之量為6重量份至8重量份。
於本發明生物纖維漿料之部分實施態樣中,分散介質與防乾劑之體積比為10:1至20:1,例如10:1至15:1。
本發明之另一目的在於提供一種製備乾式生物纖維材料之方法,包含以下指定順序之步驟:一抄造步驟,將上述生物纖維漿料覆於一多孔性支撐基材上,以於多孔性支撐基材上形成一生物纖維材料膜;一烘乾步驟,去除生物纖維材料膜中的至少部分分散介質;以及一熱壓步驟,熱壓生物纖維材料膜以獲得該乾式生物纖維材料。
於本發明方法之部分實施態樣中,烘乾步驟係於80℃至100℃之溫度下持續1分鐘至10分鐘。
於本發明方法之部分實施態樣中,熱壓步驟係於120℃至150℃之溫度下持續5秒至30秒,其中生物纖維材料膜未與多孔性支撐基材接觸之表面較佳經熱壓10秒至20秒,且生物纖維材料膜與多孔性支撐基材接觸之表面較佳經熱壓5秒至10秒。
本發明之再一目的在於提供一種乾式生物纖維材料,其係由上述製備乾式生物纖維材料之方法所製得,且可具有至少800%之吸濕率以及至少200公克/75平方公分的濕強力。

1.生物纖維漿料
本發明之生物纖維漿料包含生物纖維、結構纖維、接著纖維、助黏劑、防乾劑、以及分散介質等必要成分,該漿料可透過抄造技術製備乾式生物纖維材料。
結構纖維可提高所製纖維材料的結構強度及材料特性,且係選自嫘縈纖維、聚對苯二甲酸乙二酯(PET)纖維、尼龍纖維、或其組合。接著纖維係選自含聚乙烯複合纖維類,提供纖維的黏著效果,其實例包括聚乙烯-聚酯皮芯型複合纖維、聚乙烯-聚酯並列型複合纖維等,但本發明不
限於此。助黏劑係選自聚醯胺類、低密度聚乙烯類、或其組合,用於增強纖維間的黏著效果。防乾劑係選自多元醇類,可提高所製生物纖維材料之吸濕效果。分散介質可為任何可分散生物纖維漿料各成分,但不與該等成分反應的惰性介質,例如水。於本發明之部分實施態樣中,結構纖維係嫘縈纖維與聚對苯二甲酸乙二酯纖維之組合,接著纖維係聚乙烯-聚酯皮芯型複合纖維(芯層:聚酯;表皮層:聚乙烯),助黏劑係聚醯胺,防乾劑係甘油,且分散介質為水。
於本發明生物纖維漿料中,以100重量份之生物纖維計,結構纖維之量較佳為4重量份至12重量份,更佳6重量份至8重量份,接著纖維之量較佳為2重量份至8重量份,更佳3重量份至5重量份,且助黏劑之量較佳為4重量份至10重量份,更佳6重量份至8重量份。分散介質與防乾劑之體積比較佳為10:1至20:1,更佳為10:1至15:1。於上述較佳比例範圍時,本發明生物纖維漿料所製得之生物纖維材料可具有較佳的吸濕率以及濕強力。
於本發明生物纖維漿料中,生物纖維、結構纖維、接著纖維之長度可由本發明所屬技術領域具通常知識者視需要選用。就所製乾式生物纖維材料的結構強度而言,結構纖維較佳具有至少2毫米的長度,例如3毫米至30毫米,如4毫米、5毫米、6毫米、7毫米、8毫米、9毫米、10毫米、12毫米、15毫米、20毫米、或25毫米,但本發明並不限於此。就纖維間之黏著效果而言,接著纖維較佳具有至少1毫米之長度,例如2毫米至25毫米,如3毫米、4毫米、5毫米、6毫米、7毫米、8毫米、9毫米、10毫米、12毫米、15毫米、或20毫米,但本發明並不限於此。
本發明生物纖維漿料之製備,可藉由將生物纖維漿料各必要成分,包括生物纖維、結構纖維、接著纖維、助黏劑、及防乾劑,與其他
視需要之習用添加劑均勻混合並分散於分散介質而製得,其中所述習用添加劑可為任何常用於護膚膜之添加劑。分散介質與生物纖維、結構纖維、接著纖維、助黏劑等成分間之比例並無特殊限制,本發明所屬技術領域中具通常知識者可視實際需要調整,例如可先以少量分散介質將生物纖維漿料各成分均勻分散,以濃縮漿料形式運送或販售,於實際使用時再添加適量之分散介質稀釋。
2.製備乾式生物纖維材料之方法
本發明亦提供一種使用上述生物纖維漿料以製備乾式生物纖維材料之方法,該方法依序包含抄造步驟、烘乾步驟以及熱壓步驟。於抄造步驟中,生物纖維漿料被覆於一作為襯布之多孔性支撐基材上,而於其上形成一生物纖維材料膜。於烘乾步驟中生物纖維材料膜中的至少部分分散介質被烘乾去除。於熱壓步驟中,透過熱壓合的方式,使纖維彼此黏著在一起以形成乾式生物纖維材料。
可使用如圖1所示意之抄造設備實施本發明製備乾式生物纖維材料之方法。首先,將經粉碎機絞碎之生物纖維、結構纖維、接著纖維、助黏劑、及防乾劑於混料槽100中混合均勻,所得混合物接著與循環水槽200的水於抄造箱300中混合均勻,形成生物纖維漿料。接著進行抄造程序以將生物纖維漿料覆於襯布(圖未示出)上,形成一生物纖維材料膜。利用吸水輸送帶將生物纖維材料膜輸送至烘箱400烘乾,以去除部分分散介質。烘乾後之生物纖維材料膜接著以熱壓滾輪500熱壓,以製得乾式生物纖維材料。所製得之乾式生物纖維材料並可利用捲取機構600捲成捲材保存。
於本發明之方法中,烘乾步驟之烘乾溫度較佳為80℃至100℃,例如85℃、90℃、或95℃,烘乾持續時間較佳為1分鐘至10分
鐘,例如2分鐘、3分鐘、4分鐘、5分鐘、6分鐘、7分鐘、8分鐘、或9分鐘。熱壓步驟之熱壓溫度應至少高於接著纖維及助黏劑的熔點,俾提供所須之黏著效果,且較佳為120℃至150℃,例如125℃、130℃、135℃、140℃、或145℃。熱壓持續時間較佳為5秒至30秒,例如15秒、20秒、或25秒。此外,更佳對生物纖維材料膜之二面分別進行熱壓,其中生物纖維材料膜未與多孔性支撐基材接觸之表面較佳熱壓10秒至20秒,且生物纖維材料膜與多孔性支撐基材接觸之表面較佳熱壓5秒至10秒。於上述烘乾及熱壓條件下,本發明方法所製得之乾式生物纖維材料可具有甚至更佳的吸濕率以及濕強力。
本發明方法可連續式地操作,且所製得之乾式生物纖維材料可成捲保存,在製造成本、儲存及運送上均有顯著優勢。此外,本發明方法上述步驟均為物理性處理,因此本發明方法尚具有環保優勢。
3.乾式生物纖維材料
本發明亦提供一種由上述方法所製得之乾式生物纖維材料,該乾式生物纖維材料可被連續地製造成捲材,成功解決傳統生物纖維材料必須保持濕潤,不利於儲存及運送的問題。於本發明之較佳實施態樣中,乾式生物纖維材料係具有至少800%之吸濕率以及至少200公克/75平方公分的濕強力,例如850%、950%、1000%、1050%、1100%、1150%、1200%、1250%、1300%、1350%、1400%、1450%、或1500%之吸濕率,以及250公克/75平方公分、300公克/75平方公分、350公克/75平方公分、400公克/75平方公分、450公克/75平方公分、500公克/75平方公分、550公克/75平方公分、或600公克/75平方公分的濕強力。於本文中,乾式生物纖維材料之吸濕率及濕強力係根據實施例所述量測方式量測。
4.護膚膜
本發明乾式生物纖維材料具有優異吸濕率及濕強力,可作為護膚膜的基材使用。因此,本發明亦提供一種護膚膜,該護膚膜包含一基材以及一附於基材上之護膚成分,其中係使用上述乾式生物纖維材料作為該基材。護膚膜之實例包括但不限於面膜、指膜、及腳膜。護膚膜之護膚成分的種類並無特殊限制,可為任何本領域習知可用於提供護膚效果的成分,例如茶多酚、玻尿酸等,但本發明並不限於此。本發明之護膚膜除具有生物纖維材料本身之優點外,更因為基材本身的良好吸濕率及濕強力,使得護膚膜中含有大量的護膚成分,且護膚膜在吸附護膚成分的情況下仍具有優異的強度。
5.實施例
5.1.量測方式說明
茲以下列具體實施態樣進一步例示說明本發明,其中,所採用之量測儀器及方法分別如下:
[吸濕率測試]
取5公分×5公分之樣品,於60℃烘箱烘乾24小時後秤重,此為乾重。接著將樣品浸沒於流動水中5秒,取出吸濕飽和垂流1分鐘後秤重,此為濕重。以如下算式計算樣品之吸濕率:
[濕強力測試]
以萬能強力試驗機進行濕強力測試(夾頭速度:200公分/分鐘),其中係使用5公分×15公分之樣品,且在進行濕強力測試前先使該樣品吸附與樣品本身等重的水。
5.2.乾式生物纖維材料之製備
使用如圖1所示意之抄造設備製備乾式生物纖維材料。首先,以如表1所示之比例,將經粉碎機絞碎之生物纖維、結構纖維、接著纖維、助黏劑、及防乾劑於混料槽100中混合均勻,所得之混合物接著與來自循環水槽200的水於抄造箱300中混合均勻,形成生物纖維漿料。接著進行抄造程序以將生物纖維漿料覆於PET襯布(圖未示出)上,形成生物纖維材料膜,再利用吸水輸送帶將生物纖維材料膜輸送至烘箱400中烘乾(烘乾溫度:80℃;烘乾持續時間:3分鐘),將烘乾後之生物纖維材料膜以熱壓滾輪500熱壓(熱壓溫度:120℃;熱壓持續時間:正面壓合10秒,反面壓合5秒,其中生物纖維材料膜未與多孔性支撐基材接觸之表面為正面,生物纖維材料膜與多孔性支撐基材接觸之表面為反面),以製得乾式生物纖維材料。所製得之乾式生物纖維材料利用捲取機構600捲成捲材保存。
5.3.乾式生物纖維材料之性質測試
量測將所製得之乾式生物纖維材料的基重、厚度、吸濕率及濕強力,並將結果紀錄於下表2中。
如表2所示,本發明之乾式生物纖維材料具有優異的吸濕率(1380%)及濕強力(480公克/75平方公分),適合作為護膚膜的基材。
上述實施例僅為例示性說明本發明之原理及其功效,並闡述本發明之技術特徵,而非用於限制本發明之保護範疇。任何熟悉本技術者在不違背本發明之技術原理及精神下,可輕易完成之改變或安排,均屬本發明所主張之範圍。因此,本發明之權利保護範圍係如後附申請專利範圍所列。
