1330213 玖、發明說明: C發明所厲之技術領域3 發明領域 本發明係有關於造纸工藝。詳言之,本發明係有關於 5 一種乾燥機織物,雖然它在任何用於造紙機之成型、壓製 和乾燥部分之織物中,以及廣義的工業製程織物和波紋織 物中,皆有可能獲得應用。 此處所指之工業製程織物可包括用於濕法縴網產品之 製造等的織物,如纸張和紙板、衛生紙及纸巾產品;用於 10 使用熱風乾燥技術之面紙和紙巾產品製造的織物;用以製 造瓦楞紙板之瓦楞帶;以及用於濕法縴網和乾法縴網紙漿 之製造的工程織物;用於造紙相關製程,如使用紙泥過濾 器和化學清洗機之織物;以及用於以水中糾結(濕式製程)、 熔喷成網、紡黏和空氣縴網針軋做成不織布之製造的織 15 物。此等工業製程織物包括,但不限於,不織布毛氈;用 於製造不織布之製程的壓紋、轉印和支撐織物;以及過濾 織物和過濾、布料。 瓦楞織物在此指的是所謂在用以製造瓦楞紙板之瓦楞 機上運作的瓦楞帶,如下文所述。 20 【先前技 習知技藝說明 造紙過程中,一纖維素纖維網透過將一纖維漿,亦即 纖維素纖維之水性分散,沉積於一造紙機之成形部位的移 動成形織物上之方式被形成。大部分的水分經由該成形織 5 物被排出該漿’使該纖維素纖維網保留在該成形織物之表 面。. 剛成形之纖維素纖維網從該成形部位前進至/壓擠部 位,該壓擠部位包括一連串的壓擠夾口。該纖維素纖維網 通過該壓擠夾口,該壓擠夾口由一壓擠織物支撐,或者, 在通常情況下,由兩個此等壓擠織物支撐。在該歷擠爽口 中,該纖維素纖維網承受壓縮力以將水分從中擠壓出來, 亚使該網中之纖維素纖維互相黏合以將該纖維素纖維網轉 文成紙張。水分由該壓擠織物或壓撥織物群接收,並且 不會返回該紙張。 取後該紙張進入-乾燥部位,該乾躁部位包括至少一 系列之以蒸氣在内部加熱的可旋轉乾燥鼓錢筒。剛成形 之紙張沿各賴被—乾賴織物料導人-祕通道,該 碗蜒通道使該紙„_鼓之表面。被加狀減透過蒸 發’將該紙張之水分減少至-期望程度。 應予理解的是,該成形、厂堅擠和乾燥機織物在該造紙 機上^ h取無端迴路之形式,並以輸送帶方式運作。此外, 紙張衣作為”種以向速進行之連續式製程。換言之,該纖 •隹及被連g積於4成形部位之該成形織物上,而新製作 完成之紙關錢一絲抑1 .現代t被製作成各式各樣的風格以迎合供其安裝之 造紙機對製' 中之紙張等級的需求。—般來說它們包括 一交織1賴型的基礎織物。此外,如同該壓梭部位中 所使用之織物,該严轉織物具有一或更多其中縫有一細敏 不織布纖維材料做成之舖棉的基礎織物。該基礎織物可以 單絲、膠合單絲、多絲或膠合多絲紗線織,也可以是單層、 多層或貼合形式。該紗線基本上係從任何合成聚合樹脂曰, 如造紙機造紙領域中具有普通技藝之人士會選用的聚醒胺 和聚酯樹脂擠壓成的。 "亥父編基礎織物本身具有許多不同的形式。舉例言 它們可以無盡交織、或平織,然後以_接縫做成無盡 形式。選擇性地,它們可以一通稱為修飾盔 ^作,其中該基礎織物之寬度邊相其機器方向(MD)紗線 :置縫合迴路。在此-製程中’該MD紗線在該織物之該寬 ^邊緣之間連續且前後地交織,於各個邊緣處迴轉並形成 Z縫合迴路。以此方式做成之基礎織物在安裳於造紙機上 才乂無端形式被配置,也因此,被通稱為機器可縫合型織 2 °欲使此-織物做成無端形式時,需將該兩寬度邊緣接 合在一起,令該兩邊緣處之該縫合迴路互相交錯,且使一 縫合別針或_穿職交錯縫合祕卿成之通道。 再者,该父織基礎織物可以藉由將至少一基礎織物設 於另基礎織物所形成之無端迴路中,且在這些基礎織 &中縫上Μ%纖維舖棉以將其互相接合成壓擠織物形式 ^方式膠合。這些交織基礎織物中有一者或多者可為機器 可縫合裂。le即疋現在廣為人知之具有多重基礎支撐結構 的膠合壓擠織物。 無論如何’該織物呈無端迴路形式,或者可以縫合成 下形式八有沿其縱向量測之特定長度,以及一沿其 7 口瓦愣π通常為平織之多層式織物,各該織物被交織, 或在長、寬方向上被修整至—適合供其安裝之瓦愣機使用 ▲、尺寸或長度和寬度q辑物之端部設有縫合構件,以便 Λ瓦榜ΤΓ破f裝於該瓦愣機上時,它們可以透過—別針、 5 樞軸、或纜線互相接合。 2典型的瓦愣機中’該加熱區包括一㈣的熱板,該 瓦愣π在4彡列熱板上拖良該瓦榜板薄片。複數個位在 由該瓦楞帶形成之該無端迴路中的加權親筒將該瓦愣帶壓 向錢板’以便該瓦愣帶可以在—選擇的壓力下於該熱板 10上拖H專片。該加權報筒確保該薄片可以被堅固地壓向 該熱板’且該瓦楞帶與該薄片之間的摩擦力大至足以使該 帶有能力拖曳該薄片。
在新一代的瓦楞機中,該加權輥筒已被氣動軸承取 代’該氣動軸承將-高速率氣流導至該瓦愣帶之該後側並 15朝向遠熱板,以迫使該瓦榜帶面向該熱板。為了避免該高 速率氡流穿過該瓦榜帶,致使該帶從該瓦榜板薄片被舉起 並使忒薄片在相對於该帶之移動方向上滑動從而導致該 薄片和該熱板之間接觸不良並在最終之膠合瓦楞板產品中 產生粗劣且不均勻的黏合,機器上所用之該瓦楞帶上具有 20該氣動軸承的該後側設有一聚合樹脂材料層,該聚合樹脂 材料層不透水且將該瓦愣帶密封以防止空氣從中穿過。I 述技藝之更詳細的說明記載於,比方說,美國專利第 6,186,209號中。 在一更新一代的瓦楞機中,將瓦楞板網壓向該熱板之 該瓦榜帶已被省去不用,以避免與該帶有關的問題,如縫 合s己號、邊緣塵壞、邊緣磨損以及板扭曲。取而代之地, 一對設於該加熱區下游該冷卻區中之皮帶夾於該瓦楞板薄 片之上、下方且將其拖曳過s玄冷卻區。 我們發現,現有的瓦楞帶在安裝於此一最新一代的瓦 楞機上後操作並不令人十分滿意。目前,瓦楞帶具有一針 縫或交織表面,其相對於瓦愣板的摩擦係數在〇15至〇 2〇 之間。由於該瓦楞帶只有在該冷卻區中於一總面積遠小於 舊式機種的區域内接觸該瓦楞板網,現有的皮帶始終無法 產生大至足以在該瓦楞機上拖曳該網之磨擦力。 顯然地,此一最新型的瓦愣機所需要之瓦愣帶,其表 面之相對於該瓦楞板的摩擦係數必須比現存者更大,以便 使它們可以產生所需要的摩擦力。此種瓦楞帶揭示於,比 方說’美_專利第6,276,420號中。 現在我們更精確地描述造紙機之乾燥部位中所使用的 織物,乾燥輥筒通常被設置於最上方和最下方之排或階。 位在最下階者與位在最上階者交錯排開,而非構成一完全 垂直之關係。當被乾燥之紙張前進至該乾燥區時,它會藉 由先穿過該兩階中之—階裡的乾燥耗筒,再穿過該兩階中 之另一階裡的乾燥輥筒,然後以此類推地依序穿過該乾燥 邛位的方式,在該最上階和該最下階之間交替。 在許多乾燥部位中,該乾燥輕筒之該最上階和該最下 階分別被彼覆-分離的乾燥機織物。在此—類型的乾燥部 位中’被乾燥之紙張未觉支撐地穿過—階中之乾燥輥筒和 另一階中之乾燥輥筒之間的空間,或者“口袋,,β 當機器速度增加時,被乾燥之紙張在通過該口袋時容 易亂飛’也常常斷裂。因此需要使整台造紙機停機,然後 再讓紙張重新通過該乾燥部位m要對生產速度 及效率具有負面的衝擊。 為了增加生產速度並降低對紙張的干擾,單次運轉之 乾燥部位以比傳統乾燥部位所能達成者更高的速度運送被 乾燥之紙張。錢單次·之㈣部位中,—單—乾燥機 織物依序㈣循n該最切和該最下时之該乾燥輥 筒設置的祕Hit前進。以此方^,該紙張找最上階和 該最下階之間被導引以通過該口袋部位,即使實際上並沒 有受到支撐。 我們可以理解,在該單次運轉之乾燥部位中該乾燥 機織物使被乾燥之紙張直接貼向該兩階中之―階裡的乾燥 幸昆筒’但在該㈣中之另—階裡的乾燥輥筒中運載該紙 張。選擇性地’該單次運轉之乾燥部位可具有僅只一階的 乾燥輥筒。此種乾燥部位具有—轉動輥筒,該轉動輥筒在 位於每對減之間之該α袋處可以呈平滑狀、設以凹槽, 或者提供吸引構件。此種乾燥部位被泛稱為單階乾燥部位。 由移動中之該乾燥機織物的後側表面運載之空氣在狹 乍空間中形成-壓縮楔子,在該狹窄空間内,移動中之該 乾燥機織物迫近-乾燥_或轉域筒。該壓馳子中: 乳壓的增加使空氣向外流過該乾燥機織物。此—氣流在紙 張不是介於該乾燥機織物和該乾雜筒之間時,會進而使 1330213 該紙張飄離該乾燥機織物之紙張接觸表面,此即所謂的“下 降”現象。“下降”可能由於造成邊緣碎裂而降低製造中之紙 張產品的品質’而假使其導致紙張破碎,還可能進—步降 低機器效率。 5 許多造紙廠企圖透過以機器在與該單階乾燥機織物直 接接觸之該轉動I昆筒中製造凹槽,或者藉由將一真空源添 加至該轉動輥筒之方式來解決此一問題。這些權宜之計皆 可使困於該壓縮楔子中之空氣被移除而無須穿過該乾燥機 織物。 10 在此一方面,織物製造商亦採用塗層方式將其應用至 織物上以賦予額外的功能性,如“紙張緊縮法”。運用塗層 以增加此一功能性至比方說乾燥機織物的重要性已由
Luciano-Fagerholm (美國專利第 5,829,488 (Albany))於名為 "Dryer Fabric With Hydrophilic Paper Contacting Surfaced 15 發明中闡明。
Luciano和Fagerholm已述及織物之水性表面處理在提 供紙張支撐特性並維持接近原始滲透性上的用法。然而, 雖然此一處理織物表面的方法成功地賦予紙張缚束力,仍 有需要對塗層的親水性和耐久性加強。w〇專利97/14846亦 20強調紙張缚束法的重要性,並提及使用矽酮塗覆材料來完 全覆蓋並使織物飽和,從而使其實質地無法滲透的方法。 然而,此一滲透性的大幅降低對乾燥機織物應用來說,並 無法接受。紙張縛東力在美國專利第5,397,438號中亦有論 述’該專利係有關於將黏著劑塗佈至織物的橫向區域以避 12
