1232248 A7 ______B7_ 五、發明說明(I ) 詳細說明 枝術領域 除塵室用的護衣的作用,係將室中所製或所加工的產品 (例如微電子零件,醫藥,光學玻璃纖維)保護以免受人體 景> 響(此處人體係排放有害粒子的「來源」,例如灰塵、 皮膚屑粒子、細菌)。 因此,對於製造此類護套用的材料的重要需求爲屏障 作用。護套材料須對人體不斷釋放出的粒子(皮膚屑、斷 髮片段、細菌等)以及由紡織品之內衣釋出的纖維斷片阻 lea住’以避免除塵室空氣及產品受污染。當然,這種材料 本身也不能將纖維部分或其他成份排放到除塵室空氣中。 除了所需的屏障作用外,該護套層材料須能承受高機 械負荷,特別是有高的再撕裂及撕裂強度,以將由於外來 作用或正常穿著造成的應力造成之裂縫或孔形成的危險減 至最低。爲了使該護衣也能多次再使用,該材料還要能承 受一般洗濯或淸洗程序(例如在高壓釜中消毒)而儘量不 受損’亦即對於濕機械磨損及起球(疵點)(Pilling))有抵 抗力,且其尺寸穩定不變。 除了屏障作用與濕機械抵抗力外,這種護衣材料特別 是用於微電子工業中者須有抗靜電作用,換言之,這種護 衣須不受到穿著時不可避免的摩擦而帶了過量的靜電荷, 或者是能將一些靜電荷迅速消散或導離。這點係必需者, 以便一方面使敏感的微電子元件不會受到點狀放電損壞, 另方面也不會從周圍空氣吸收灰塵粒子(否則這些灰塵粒 3 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) " -------------K-----訂-----—線 (請先閱讀背面之注意事項再填寫本頁) A7 1232248 _ B7____ 五、發明說明(*/) 子可能會跑到衣材料表面,而在以後可能再排放出來)。 此外,該護衣材料也要有夠高的穿著舒適度,換言之 ,在垂落(Fall),手感(Griff英:hand feeling)及光學性質方 面要有儘量像紡織品的特性,而且要有空氣活性(透氣) 及保暖絕熱,以避免穿著的人過度的流汗(Schwitzen)或受 寒(Frieren) 〇 習知技術 人們知道使用最細纖度的合成纖維或合成長絲製造除 塵室護衣材料。此外「最細纖度」一詞係指纖度小於ldtex 的纖維,它也被稱爲「微纖維」。對於纖度小於〇.3dtex的 微纖維也用「超微纖維」一詞。 一般以微纖維或微長絲的梭織布或編織物爲基礎的護 衣材料分數道程序步驟製造。首先由聚合物原料紡成微纖 維或長絲。然後將它們再加工成紗,該紗如有必要還可通 過一道隨後之締捲程序。最後由此(締捲過的)微纖維或微 長絲紗織成基本的護衣材料。在力織程序,還可將導電的 紗呈現則圖案方式例如呈條紋狀或方格紋(Kar〇英 ·· carreau 或check))排列織入,以達到所需之抗靜電作用。舉例而言 ’導電紗含有具有含碳黑或石墨的核心或函殻的核心/函 威長絲’或者如金屬纖維或鍍金屬的長絲。所需的屏障功 能及高度的(濕)機械負荷性係利用微纖維的一種極密且 規則的纖合而達成。但這種高織密度及主要與表面平行的 長絲走向就材料透氣活性觀之却是不利的。它只有少許微 孔隙可使水蒸氣經該微孔隙透過布。 4 本紙張尺度適用中國國-- ---------------:-----訂---------線 (請先閲讀背面之注意事項再填寫本頁) 1232248
五、發明說明($ ) 蒦衣材料屏障作用及透氣活性造成的有問題(互相 揮丁突)的性質的組合可藉使用粒子密度高但却透水蒸氣的 月旲^成°這種「微孔隙」層可藉(例如)層疊(層壓、膠 3 ) ( Laminierung 英:laminating )或直接擠壓 (Dii*ektextrusi〇n 英:direct extrusion)而施到普通密度的紡織 品材料’以得到具紡織品性質的材料。 胃密度微長絲布以及由透氣活性屏障膜及紡織品構成 的複合材料的製造程序因而較花時間。較易製造的替代方 案爲微纖維不織布。 以聚乙烯荷基礎的平坦砑光的微長絲紡紗不織布可滿 足這種屏障要求,此外可很廉價地製造。但這種材料實際 上却密不透氣及不透水,且見有箔片式特性,換言之,其 穿著舒適性低。此外,它們的耐洗性或耐淸理性不足,因 此它們限於用在一次用後即丟(Emweg)或拋棄式(Wegwerf 英:disposable)的護衣方面用途。 由多片段式或由多核心式短纖維製造的微纖維不織布 (該纖維在排放成不織布以及可能之預鞏固作業後,利用 溶劑或水柱劈分成個別的微長絲)在有良好的屏障作用的 場合下,其穿著舒適度須遠比上述之高砑光微長絲紡織不 織布更好。 舉例而言,歐洲專利0624676提到一種方法,說到如 何能利用水柱劈分製造具有極高塡充密度及良好屏障作用 的微纖維不織布。但這種不織布缺少柔軟性及熱絕緣性質 。因此人們認爲使用藉水柱鞏固的不織布以作護衣所能的 5 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) (請先閲讀背面之注意事項再填寫本頁) —I-----訂---------線一 1232248 A7 ____B7_____ 五、發明說明(if) 應用範圍很有限。因此上述專利案中提到另一種方法,其 中不使用水柱技術。 在國際專利(PCT)申請案W0 98123804中提到與上述專 利案不同的方式,係將不織布在水柱劈分之前,首先作熱 作點狀熔接。如此可防止不織布在水柱劈分時,與水柱機 組的篩網帶鈞掛在一起,然後在揭起時受損甚至破壞。另 一方面,須因此達到較高程度的纖維劈分,如此達成較佳 皂屏障性質及手感(Tast)。 在歐洲專利97 108 364中也提到將不織布應用領域擴 充。其中提到由很細的長絲製造不織布,該布須具有與梭織 式編織的紡織品有相當的性質。這種纖度0.005〜2dtex的 很細的長絲利用水柱劈分由熔紡之捲曲(Kraeuseln英 ••Crimp)或未捲曲的多成份多片段長絲(其纖度〇.3dtex〜 lOdtex)產生。如此所得的不織布還可用各種不同方式作 後加工,例如利用熱固定,點上膠等),以達成特別應用 性質。依此方法製造的紡絲不織布特別適合製造衣著及其 他紡織品產物。 本發明的說明 在以下的硏究中,出乎意料地得知··如果將上述EP 專利案97108364所製的不織布用纖度小於〇.2dtex的超微 長絲構成’並另外作凹凸軋花(拷花)(Praegekalandrieren 央:calemdering) ’則該不織布極適合製造除塵室的護衣, 此超微長絲本身利用水柱劈分由纖度小於2dtex的多成份 長絲產生,該多成份長絲係用熔紡程序形成,用空氣動力 6 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) ---- ------------Γ-----訂---------線 (請先閱讀背面之注意事項再填寫本頁) 丨 1232248 A7 ; _B7__ / "" * —- ..- 五、發明說明(ΐ ) ! / . | 方式牽伸,且用水柱作預結合。 以下本發明提到一種新式不織布材料及其製造方法步 驟。此不織布滿足一種可多次再使用的除塵室護衣材料的 所有要求。它的特色爲具有高度屏障作用,高機械負荷性 及尺寸度量的穩定性,有效率的抗靜電作用及高度穿著適 度(透氣性及紡織品性質)。這些有利的性質即使在多次 一般的洗濯或淸洗程序(多達30循環)仍保持在足夠的範 圍。迄今利用具劈分之最細長絲的不織布,一般認爲是不 可能同時達到這些性質的。 此不織布由纖度小於0.2dtex的超微長絲構成,該超微 長絲由纖度1.5〜2dtex的未捲曲的初級長絲製成。所用之 初級長絲宜爲—^成份多片段長絲,由二種不相容的聚合物 構成,特別是由聚酯與聚醯胺構成。這種二種成份的長絲 係習知者,如EP97108364所述。聚酯的比例選設成比聚醯 胺高,宜在60〜70%重量之間。爲了達成所要的抗靜電作 用。故該二種聚合物之一或全部都加有對應之長期有效( 亦即不能被取代或交換的)添加劑。舉例而言,這種抗靜 電作用可藉混入碳黑或石墨或混以具有強親水特性的聚合 物或具(半)導電性質的聚合物達成,必要時還可加入相 容化的藥劑。此初級雙成份長絲的橫截面呈橘瓣形多片段 構造(「派餅構造」)。這些片段包含交替的不相容之加 有添加物的聚合物。這種習知的長絲橫截面對於以下所述 之超微長絲的產生作用顯示出很有利。爲了達成該不織布 之所要的抗磨強度及小的起球(Pilling)傾向,故在一般的空 7 ---------訂---------線 f請先閱讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) 1232248 A7 ___B7___ 五、發明說明(G ) (請先閱讀背面之注意事項再填寫本頁) 氣動力牽伸後,將該長絲作另一道牽伸同時作熱煮處理 (Tempera 英:anneal)程序(熱通道牽伸「Hot-Channel Stretching」)。 如此所產生的初級長絲利用特殊機組以不規則排列放 在一條移動的帶子上,然後利用傳統水柱技術預先鞏固, 亦即使它們以機械方式互相纏結(verschlingen英:snarling) 。然後將此預鞏固的初級長絲不織布在穿了孔的轉鼓上多 次的將兩面施以尚壓水柱,如此該初級長絲實際上已崩解 成其個別成份,亦即崩解成個別的超微長絲,且這些超微 長絲同時極均勻地互相糾纏(Verwirbeln英:entangle)。利 用這種程序步驟產生一種微纖維不織布,它由於極高不規 則及糾纏的纖維構造,故一方面具有所需之屏障作用,但 另一方面仍有充分的透水氣性。 爲了要改善在洗濯及淸洗時的尺寸度量穩定性,故該 微纖維不織布在水柱劈分及隨後之乾燥作業後在張力之下 受到一道熱空氣熱固定程序。然後將該不織布在具有特別 刻紋(Gravatur英:engraving)滾子的研光機中作凹凸壓花 (Pragekalandrieren,英:embossing calender),以提高度量尺 寸穩定性及耐磨性。製成之不織布的基重爲80〜150克/平 方米,且宜95〜115克/平方米。 [實例] 首先由二成份長絲[由70%聚(乙烯對苯二甲酸酯)及 30%聚(六甲撐己二醯胺)構成]製造一種均勻厚度之不織布 基重(FlSchengewicht,英:area density),(面密度,單位面 8 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) A7 1232248 ____B7___ 五、發明說明(1 ) 積重量95克/平方米。初級長絲的纖度1.6dtex,且含有 一六個片段,它們交替地由聚酯或聚醯胺構成。此熔紡的 長絲用空氣動力方式牽伸,不規則地放在一帶上,並送去 一水柱處理單元,在其中使長絲預鞏固。然後將預鞏固的 不織布用高壓水柱處理,如此使初級長絲劈裂成個別的片 段,且將這些片段再變成紗球(KnSuel,英:yarn boll)。此 水柱劈裂作業係由不織布兩面作數次。產生的超微長絲的 平均纖度O.ldtex,且未捲曲。然後將此預鞏固的不織布用 高壓水柱處理,如此該初級長絲劈裂分成個別的片段,且 個別片段再捲曲。水柱劈分作業由不織布兩面作數次。產 生的超微長絲的平均纖度O.ldtex,且不捲曲。然後將此不 織布乾燥並作鐫印砑光。如此所製的不織布的過濾效率, 對於-0.5//m的粒子爲約60%,對的粒子約98%。 用標準洗濯劑在40°C作洗濯處理二十次後’過濾效率只下 降一點點,對-0.5//m的粒子約55%,對-l//m的粒子約 95%。 9 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) ------------MwrlIl·—— 丨訂---------線 (請先閱讀背面之注意事項再填寫本頁)
