200302112 玖、發明說明 實施方式及圖式簡單說明) (發明說明應敘明:發明所屬之技術領域、先前技術、 t 明所屬領^^ 發明領域 本發明係關於-種包含顆粒的纖維狀結構之纖維性材料 ’其可用來製造拋棄式尿布、成年大小便失禁塾、衛生棉 及其類似物。更特別地是,本發明係針對一種具有非常高 顆粒載量的纖維狀物體,特別是超吸收體聚合物之顆粒。 I:先前技術3 發明背景 10 吸收物體(諸如拋棄式尿布、成年大小便失禁墊 '衛 生棉、衛生護墊及其類似物)通常會提供一吸收核心以接 受及保留體液。該吸收核心通常會失在能透液體的頂端薄 片(其功能為讓液體通過而到達該核心)與不能透液體的後 端薄片(其功能^包含住液體且防止其通過該0及收物體到 15達穿戴該吸收物體之人士的衣物)中間。 用於尿布及成年大小便失禁墊的吸收核心時常包含一 由已去纖維化、鬆散、已短纖化、親水的纖維素纖維所構 成之纖維狀絮墊或網狀織物。該核心亦可包括一包含超吸 收體聚合物(SAP)顆粒、細粒、薄片或纖維之層或薄層 20 (stratuni)(經常指為儲存層或薄層)。 在最近幾年中,市場對漸漸較薄且更舒適的吸收物體 之需求已增加。此物體可藉由減少尿布核心的厚度、藉由 減少使用在核心的纖維性材料量同時增加SAp顆粒的量、 及藉由輪壓或加麼該核心以減低卡尺⑽一)(因此增加密 200302112 玖、發明說明 度)而獲得。 此較高密度的核心不會如較低密度核心般快速地吸收 液體’因為緊密的核心(密實化)會產生較小的有效孔洞尺 寸。因此’為了維持合適的液體吸收性,需要提供一具有 5 孔洞尺寸大於高密度吸收核心之較低密度層,以增加排放 到吸收物體上之液體吸收速率。該低密度層典型地指為一 採集層(acquisition layer)。多層吸收核心設計則包含更複 雜的製造製程。 拋棄式尿布的儲存層部分通常例如可在轉換製程 10 (C〇nver>ting Process)期間適當地從鬆散、短纖化的纖維素 形成。此纖維素材料通常無法以預先形成的滾筒形式獲得 ,因為其不具有足夠的網狀織物強度(由於其缺乏纖維間 的黏合或纏結)而無法在吸收墊製造設備中直接捲繞上去 及處理。 15 超薄的女性衛生棉通常從以滾筒狀商品為基礎的不織 材料製造。此預先形成的吸收核心材料之滾筒可直接去捲 繞至吸收物體轉換設備上,而沒有以短纖為基礎的產物( 諸如尿布及大小便失禁墊)所需之去纖維化步驟。該不織 的網狀織物在轉換製程中典型地會以能提供足夠的處理強 2〇度之方式黏合或固結。這些網狀織物亦可包含SAp顆粒。 在以滾筒狀商品方式製得預先形成的核心中,所使用 之網狀織物強化機制能對該網狀織物提供強度及尺寸穩定 性。此機制包括膠乳黏合、與熱塑性或雙組分纖維或熱塑 t生粕末黏合、水纏結(hydr〇entanglemem)、針刺法、梳理 200302112 玖、發明說明 法或其類似的方法。但是,在高顆粒載量下,該核心結構 -有差的顆粒裝承性。換句話說,某些顆粒會在製造、處 —裝運及轉換期間和在使用時趨向於從結構中漏出。此 可^ &成裏造及轉換設備骯髒和對該產物有負面的消費觀 5 念。 對一吸收核心材料來說,已所需的有其可使液體容易 從才木集區域運达至儲存區域、其在高顆粒載量下具有好的 顆粒裝承性、其可甚至在高顆粒载量下亦提供高挽性、其 ^薄的但是在使用時具有高吸收容量、及其可以滾筒_ 10品形式輪送而簡化製造及轉換製程。 已公告的PCT申請案贾〇 00/71790揭示出一種包含— 官能性顆粒(其選擇性地提供在一些線道〇anes)中)層之吸 收物體,其中該物體的侧邊邊緣並無官能性顆粒且可密封 以將該些鬆散顆粒包含在該結構内。 本1¾明之目標為提供一種纖維狀網狀織物,其包含一 以高載量存在的官能性顆粒,且其可形成—吸收物體。3 本發明之另-個目標為提供一種製造纖維狀網狀織物 的方法,該織物包含一以高載量存在的官能性顆粒且可形 成吸收物體。 2〇

粒的線道或區域,且每條線道或區域與她連的線道或區域 12 200302112 玖、發明說明 相隔離° ®比連的官能性顆粒薄層已經定向,如此當在z方 向上觀看該網狀織物時,一層的官能性顆粒薄層之官能性 顆粒線道或區域並不與下一層毗連的官能性顆粒薄層之官 成性顆粒線道或區域直接重疊或疊印在一起。換句話說, 5第一官能性顆粒薄層的線道或區域與下一層毗連的官能性 顆粒薄層之線道或區域互補。 參考至第1圖,其顯示出一官能性顆粒薄層的俯視圖 在個較佳的具體實施例中,本發明之結構可使用空氣 此降技術來製備。為了參考的目的,該些圖顯示出本發明 於MD或機器方向上(亦指為γ方向)延伸之結構。CD或交叉 方向則垂直於MD。最後地,z方向指為該結構的厚度並與 X-Y平面正交。 第1圖之薄層2包含數條在γ方向上縱向延伸的線道6及 8。每條線道皆包含官能性顆粒。薄層2的邊緣⑺並無官能 15 20 f生顆粒。在每條線道間之間隔14亦無官能性顆粒。薄層2 可鋪在另-官能性顆粒薄層上㈣在另—不包含官能性顆 粒的薄層上方。參照第2圖,其顯示出第二官能性顆粒薄 層4。此薄層亦包含縱向延伸的官能性顆粒線道。但是, 該些線道如此配置,使得當薄層2鋪在薄層4上方時,當從 Z方向觀看時,該些線道將*會疊印在_起。類似地,薄 層2的線道將不會疊印在薄層4的線道上方,甚至當在薄層 2與4之間配置一不含官能性顆粒的插入薄層時。 在薄層2及4中之線道間的間隔14較佳地實質上無官能 性顆粒、纖維或任何其它材料。可選擇性地在該些線道之 13 200302112 坎、發明說明 間提供無官能性材料,諸如纖維。在製造製程期間,於該 些纖維藉由纖維硬化而適當地固定之前,該些顆粒會有一 小部分會從該些線道漂移至該些間隔,但沒有副作用。 參考至第3圖,其顯示出根據本發明的多層結構之截 5面(截取自X方向),其包含數層官能性顆粒薄層。第一薄 層16不包含官能性顆粒,且較佳地包含基質纖維並提供一 黏著劑。在薄層16上方提供薄層4,其在無顆粒或纖維之 線道間隔14間包含官能性顆粒的線道12。薄層“則提供在 薄層4上方。然後將薄層2配置在薄層18上方,如此該薄層 1〇的線道6及8不與薄層4的線道疊印在一起。再次,較佳的 是薄層2的間隔14並無顆粒或纖維。薄層洲提供在薄層2 上方。將另一薄層4配置在薄層2〇上方,如此線道12並不 疊印在薄層2的線道6或8上。最後地,將薄層邱供在薄 層4上方。薄層18、20及22每層並無包含官能性顆粒,且 15包含相_不同型式和量的纖維作為任一薄層或彼此。 所產生的多層結構包含纖維與官能性顆粒交替的薄層 如此孩些官能性顆粒的線道實質上由纖維包圍。 第3圖的多層結構之側邊邊緣可選擇性地提供一邊緣 密封,如描述在PCT申請案wo 〇〇/7179〇(該公告藉此以參 考方式併入本文)。 第3圖之多層結構的描述目的為闊明具有三層官能性 顆粒薄層。但是,該結構可包含如二層—樣少的此薄層, 或可為合適於特別應用之許多薄層。在較佳的具體實施例 中,可提供六層此薄層。 14 200302112 玖、發明說明 $3圖之多層結構其自身可在單一的多層結構中包含 其它薄層,以提供你丨‘ 代1/、例如一具有特定的液體採集、分佈及儲 存能力之結構。 線道 5 "亥顯不在第圖之官能性顆粒薄層的線道與薄層的 MD或Y方向平行且連續地延伸。但是,該些線道或區域( 於此之後共同指為“線道”)可以其它合適於本發明之方法 安排。例如’該些線道可保持平行,但是可週期性地提供 该些顆粒以在該些片斷之間提供具有間隙的線道片斷,如 10顯不在第7圖。再者,該些線道可在縱向上以s形鋪放,而 在線道間具有S形的間隔,如顯示在第4圖。再者,該些線 道可為沙漏形狀,如顯示在第5圖。同樣地,可使用其它 圖案,諸如圓形(第6圖)。但是,重要的是每層官能性顆粒 薄層包括含有官能性顆粒的線道及不含官能性顆粒的間隔 15二者,且必需如此安排該些圖案,使得第一官能性顆粒薄 層的線道或區域不會疊印在第二下一個B比連的官能性顆粒 之薄層線道或£域上方。儘管前述,小百分比(少於1 5 %) 的線道或區域面積互相疊印亦視為滿足此定義。 由该官能性顆粒所提供的官能性顆粒薄層之較佳覆蓋 20 量可依該些顆粒的應用及厚度、密度及其它參數而定。通 常較佳的是該薄層之線道覆蓋該薄層至少3〇%(較佳為4〇% 及最佳為50%)之X-Y區積。 官能性顆粒 該官能性顆粒線道意欲接受顆粒、薄片、粉末、細粒 15 200302112 玖、發明說明 或其類似物。 該些顆粒可包括任何具有顆粒直徑上至3,〇〇〇微米(μ)

10而使其不溶於水,❻是其仍然可在生理鹽液溶液中膨潤至 其本身重量的至少約15倍。這些超吸收體材料通常可分為 一種4、’及換句5舌說為殿粉接枝共聚物、經交聯的羧甲基 纖維素衍生物及經改質的親水性聚丙烯酸鹽類。吸收聚合 物的實例包括經水解的澱粉-丙烯腈接枝共同聚合物、經 15皂化的丙烯酸酯-乙烯基共同聚合物、經改質之已交聯的 聚乙烯醇、經中和之已交聯的聚丙婦酸、經交聯的聚丙婦 酸鹽及經羧酸化的纖維素。較佳的超吸收體材料會在吸收 流體後形成水凝膠。 該超吸收體聚合物材料具有相當高的凝膠體積和相當 2〇高的凝膠強度(如可藉由該水凝膠的剪切模數來测量)。此 較佳的材料亦包含相當低程度的聚合材料(其可藉由與合 成的尿接觸而萃取)。超吸收體聚合物已相當熟知且可從 商業上購得。實例之-為在名稱腫_(侯氣斯特·西蘭尼

及經高度純化的纖維素纖維(諸如巴可愛(Buckeye)HPF(每 種皆可購得從巴可愛技術有限公司(Buckeye Technologies Inc.),曼菲斯(Memphis),田納西州(Tennessee)))。短纖纖 20 維可與合成纖維混合,例如聚酯(諸如PET)、耐綸、聚乙 烯或聚丙烯。 該含纖維的薄層亦可包括熱塑性黏結材料,其可與纖 維素或合成纖維混合。合適的熱塑性黏結材料包含熱塑性 纖維,諸如雙組分熱塑性纖維(“bico”)。較佳的熱塑性黏 17 2o〇3〇2112 玖、發明說明 結纖維可對廣泛範圍的材料提供提高黏附力,包括合成和 天然纖維、顆粒、及合成和天然載體薄片。典型的熱塑性 雙組分纖維有賽爾邦德(Celbond)型式255雙組分纖維(從侯 氣斯特-西蘭尼斯來)。 5 其它合適的熱塑性纖維包括聚丙烯類、聚酯類、耐論 類及其它烯烴類或此些的改質物。較佳的熱塑性纖維為飛 伯維俊斯(FiberVisions)型式AL-黏附力-C雙組分纖維,其 包含一聚丙烯核心及一經活化的共聚烯烴保護層。 當該基質纖維為纖維素或合成纖維(或其混合物)時, 10 配置在官能性顆粒薄層間之每層薄層可較佳地包含約1至 20gsm的合成纖維纖維素。熱塑性黏合材料於該薄層中的 存在量可為薄層總重量的2至50重量%,更佳為3至20%, 最佳為約10%。最佳地,在該官能性顆粒薄層間之薄層包 含3.0gsm的短纖漿及l.Ogsm的雙組分。 15 黏著劑 除了上述討論的熱塑性纖維外,其它合適的可使用於 本發明之結構的黏著劑包括液體形式或具有液體载體的黏 著劑,包括乳膠黏著劑。有用的乳膠黏著劑包括醋酸乙烯 酯與丙烯酸酯的共聚物、乙烯醋酸乙烯酯共聚物、苯乙稀 2〇魏酸丁 一烯醋共聚物及聚丙烯腈類、及愛兒產物有限公司 (Air Products Inc.)出售的例如商品名稱愛兒邦德(Airb〇nd) 、愛兒弗列克斯(Airflex)及維那克(vinac)、顧德里趣化學 公司(Goodrich Chemical Co.)的駭卡(Hycar)及吉翁(Ge〇n) 、和H.B·富勒公司(Fuller Company)的弗拉列克斯(Fuiaiex) 18 200302112 玖、發明說明 。再者,該點著劑可為一種非乳膠黏著劑,諸如表氯醇及 其類似物。 ~ 本發明考慮二種個別的黏著劑應用。在第一應用中, 將黏著劑塗佈至該結構以便僅與無顆/粒的區域或線道(其 5與包含配置在第一與第二層間的顆粒之區域或線道毗連) 接觸。該黏著劑可以噴灌物、發泡體或霧狀物形式塗佈。 在較佳的具體實施例中,可稀釋該黏著劑以包含3至25% 的固體,更佳為6至12%的固體,最佳為1〇〇/0。 對作用在無顆粒區域之高度緊密化的小孔洞環境(其 10中升y成禮封)來說,該將稀釋的黏著劑可理想地具有相當 高的固體含量(諸如10%)。該環境可產生快速的毛細作用 ,且該高固體含量可減低該黏著劑漂移至網狀織物的其它 區域。 第二黏著劑應用包括將黏著劑以發泡體、喷灑物或霧 15狀物开y式塗佈至貫質上結構的全部表面(作為“整體黏著劑 )’以減低粉塵掉在該結構的外部及内部上。在較佳的具 體貫施例中’稀釋該整體黏著劑以包含1至20%的固體, 更佳為2至1〇〇/0的固體,甚至更佳為2至4〇/〇的固體,及最佳 為約3.5%的固體。因為該黏著劑將滲透以減低粉塵掉出且 20固定該官能性顆粒,其將不會對網狀織物的結構積體度提 供明顯的貢獻。 使用二種黏著劑應用可允許各自獨立地控制密封區域 的硬度及非密封區域的硬度。任一區域的硬度可藉由選擇 黏著劑的型式、固體含量及塗佈至各別區域的黏著劑量而 19 200302112 玖、發明說明 控制。此可滿足對輸送所需的密封強度且維持使用者舒服 性的足夠彈性之需求。 MJt 可使用熱活化的纖維或其它黏結劑適當地固定本發明 之、-構的纖維,以對该結構提供積體度。在某些具體實施 例中,使用熱塑性黏結材料,且當該結構藉由塵力或麼力 及熱遷密或密實化時則形成密封。該密封可藉由隨後在硬 化烤箱中硬化而進-步增強。較佳的是使用熱塑性纖維作 為黏著劑纖維,且將熱作為硬化劑。可施加熱以在空氣沉 1〇降製程的最後,或再者週期性地於製程的不同階段中,硬 化該纖維。 在另一個具體實施例中,該密封可藉由在壓實或密實 化该網狀織物之後,塗佈一液體黏著劑(或在液體載體中 的黏著劑)而提供。在此具體實施例中,該黏著劑的目標 15為與無顆粒區域接觸且避開顆粒區土或。該黏著劑會蕊吸進 入該已密實的區域,而在乾燥及硬化之後形成密封。再者 ,在這些具體實施例中,該上及下薄層可選擇性地包含一 熱塑性黏結材料。 在另一個具體實施例中,可藉由僅在無顆粒區域中塗 佈一液體黏著劑(或一在液體載體中的黏著劑)而形成密^ ’其中該黏著劑會蕊吸進入該已密實的區域,且在乾燥及 硬化後形成強的密封,而沒有密實化該無顆粒區域。 在較佳的具體實施例中,可藉由壓實或密實化該無顆 粒區域,接著塗佈—黏著劑(其目標為與無顆粒區域接觸 20 200302112 玖、發明說明 且避開該顆粒區域)而形成密封。該黏著劑會蕊吸進入該 密實化區域,且在乾燥及硬化後形成密封。在這些較佳的 具體實施例中’該上及下薄層每層皆包含—熱塑性黏結材 料’其可在密實化及硬化後增強該密封。 該熱密封實質上無官能性顆粒,且所產生的密封比在 密封界面處具有顆粒的密封還強。當本發明之結構遭受液 體損傷(insult)時,在該密封區域(其可膨潤且中斷該密封 的積體度)内實質上並無顆粒(諸如SAp顆粒)。 10 在本發明的某些具體實施例中,該物體為一種吸收物 體。該具有經改善的顆粒裝承性之纖維狀結構可以滾筒狀 商品形式(或以其它包裝形式,諸如懸掛式)輸送,且可特 別用作為可棄換式吸收物體的吸收核心,諸如尿布、成年 大小便失禁塾及短而緊的内褲、及女性衛生棉。 主發明之結構的空氣沉降,♦ 15 20 本兔明之結構較佳地製備成_空氣沉降網狀織物。該 空氣沉降網狀織物典型地可藉由分解或㈣維化—纖維素 漿m或-些薄片而製備(典型地藉由鍵磨),以提供一 經個體化的纖維。,然後,將該經個體化的纖維以空氣輸送 至在空氣沉降網狀織物形成機器上的成形頭。一些製造商 有製造該空氣沉降網狀織物形成機器,包括丹麥及當偉伯 (Denmark and Dan_Web)(亦為丹麥)的蘭菲布里泰克 (Fibretech)。該歧成形sg命紅 ^ 一形碩包括一旋轉或攪拌鼓(通常為軸承 滾道結構),其可接供

description of the invention should state: the technical field to which the invention belongs, the prior art, the field of the invention ^^ Field of the invention The invention relates to a fibrous structure containing particles Fibrous materials' which can be used to make disposable diapers, adult incontinence puppets, sanitary napkins and the like. More particularly, the present invention is directed to a fibrous object with a very high particle load, especially superabsorbent Particles of body polymers I: Prior art 3 Background of the invention 10 Absorbing objects (such as disposable diapers, adult incontinence pads' sanitary pads, sanitary pads and the like) typically provide an absorbent core to receive and retain body fluids The absorbent core is usually lost between the liquid-permeable top sheet (which functions to allow liquid to pass through to the core) and the liquid-impermeable back sheet (which functions to contain the liquid and prevent it from passing through the 0 and receiving objects). Up to 15 to the clothing of the person wearing the absorbent article). Absorbent cores for diapers and adult incontinence pads often contain A fibrous batting or mesh fabric composed of defibrillated, loose, short-fibrillated, hydrophilic cellulose fibers. The core may also include a superabsorbent polymer (SAP) particle, fine particles, A layer or thin layer of sheet or fiber 20 (stratuni) (often referred to as a storage layer or thin layer). In recent years, the market's demand for increasingly thinner and more comfortable absorbent objects has increased. This object can be achieved by Reduce the thickness of the core of the diaper, increase the amount of SAp particles by reducing the amount of fibrous material used in the core, and reduce the caliper by rolling or adding the core) (thus increasing the density of 200302112) ) And get. This higher-density core will not absorb liquid as quickly as a lower-density core because a tight core (compacting) will produce a smaller effective pore size. Therefore, in order to maintain proper liquid absorbency, it is necessary to provide a lower density layer having a size of 5 pores larger than that of the high-density absorbent core to increase the liquid absorption rate discharged onto the absorbent body. The low density layer is typically referred to as an acquisition layer. The multilayer absorptive core design involves more complex manufacturing processes. The storage layer portion of the disposable diaper can usually be appropriately formed from loose, short-fibrillated cellulose, for example, during the conversion process 10 (Conver > ting Process). This cellulosic material is usually not available in the form of pre-formed rollers because it does not have sufficient mesh fabric strength (due to its lack of fiber-to-fiber adhesion or entanglement) to be rolled up and handled directly in absorbent pad manufacturing equipment . 15 Ultra-thin feminine tampons are usually made from non-woven materials based on tumble-like products. This pre-formed core-absorbent roller can be unwound directly onto an absorbent object conversion device without the defibration steps required for staple-based products such as diapers and incontinence pads. The non-woven mesh fabric is typically bonded or consolidated during the conversion process in a manner that provides sufficient processing strength of 20 degrees. These mesh fabrics may also contain SAp particles. In pre-formed cores made in the form of drum-like products, the mesh fabric reinforcement mechanism used provides strength and dimensional stability to the mesh fabric. This mechanism includes latex bonding, bonding with thermoplastic or bicomponent fibers or thermoplastic raw meal, hydroentanglemem, acupuncture, carding 200302112 玖, description of invention or similar methods. However, at high particle loads, this core structure-has poor particle loadability. In other words, some particles tend to leak from the structure during manufacturing, handling, shipment and conversion, and during use. This can make dirty and conversion equipment dirty and have a negative consumer outlook on the product. For an absorbent core material, what is needed is a liquid that can be easily transported from the harvesting area to the storage area, it has a good particle loadability under high particle loading, and it can be used even at high particles. It also provides high pull capacity under the load, its thin but high absorption capacity in use, and it can be rotated in the form of rollers to simplify the manufacturing and conversion process. Published PCT application JA 00/71790 discloses an absorbent object comprising a layer of -functional particles (optionally provided in some lanes), where the side edges of the object are not functional The particles are sealable to include the loose particles within the structure. The objective of this paper is to provide a fibrous mesh fabric which contains a functional particle in a high load and which can form-absorb an object. 3 Another object of the present invention is to provide a method for manufacturing a fibrous mesh fabric which contains a functional particle present at a high load and can form an absorbent object. 20. Another object of the present invention is to provide an improved fibrous material comprising-high-capacity functional particles and having high flexibility.

L · z ^ r Invention Detailed description All patents and patent applications cited in this patent specification are incorporated herein by reference into this patent specification. If there is any inconsistency in terminology, this announcement is mainly based. This invention is about A layered fiber containing a thin layer of numerous functional particles Each layer of functional particles contains a line or area of functional particles, and each line or area is connected to her line or area 12 200302112 The functional particle sheet has been oriented so that when the mesh fabric is viewed in the z direction, the functional particle lines or areas of one functional particle sheet are not adjacent to the next functional particle sheet. The channels or areas of the official particles are directly overlapped or overprinted. In other words, the lines or areas of the first thin layer of functional particles are complementary to the lines or areas of the next adjacent thin layer of functional particles. To FIG. 1, which shows a top view of a thin layer of functional particles. In a preferred embodiment, the structure of the present invention can be prepared using the air-down technique. For reference purposes, the figures show a structure in which the present invention extends in the MD or machine direction (also referred to as the γ direction). The CD or cross direction is perpendicular to the MD. Finally, the z-direction refers to the thickness of the structure and is orthogonal to the X-Y plane. The thin layer 2 in FIG. 1 includes a plurality of lines 6 and 8 extending longitudinally in the γ direction. Each lane contains functional particles. The edges of the thin layer 2 are free of functional 15 20 f green particles. The space 14 between each lane is also free of functional particles. Thin layer 2 can be laid on top of another thin layer of functional particles, another thin layer that does not contain functional particles. Referring to Fig. 2, a second thin layer 4 of functional particles is shown. This thin layer also contains longitudinally extending functional particle channels. However, the lanes are configured such that when the thin layer 2 is laid on the thin layer 4, when viewed from the Z direction, the lanes will * be superimposed on _. Similarly, the tracks of the thin layer 2 will not be superimposed on the tracks of the thin layer 4, even when an intervening thin layer containing no functional particles is disposed between the thin layers 2 and 4. The spacing 14 between the tracks in the thin layers 2 and 4 is preferably substantially free of functional particles, fibers or any other material. Optionally, non-functional materials, such as fibers, can be provided between these lanes. During the manufacturing process, before the fibers are properly fixed by fiber hardening, a small portion of the particles will drift from the lanes to the spaces without side effects. Referring to Fig. 3, which shows a cross-section of a multilayer structure according to the present invention (taken from the X direction), which includes several thin layers of functional particles. The first thin layer 16 does not contain functional particles, and preferably contains matrix fibers and provides an adhesive. A thin layer 4 is provided above the thin layer 16 and contains the functional particles' channels 12 between the particle-free or fiber-free channel spaces 14. The "thin layer" is provided above the thin layer 4. The thin layer 2 is then disposed above the thin layer 18 so that the tracks 6 and 8 of the thin layer 10 do not overlap with the tracks of the thin layer 4. Again, the comparison Preferably, there are no particles or fibers in the interval 14 of the thin layer 2. The thin layer is provided above the thin layer 2. The other thin layer 4 is arranged above the thin layer 20, so that the line 12 is not superimposed on the thin layer 2. Line 6 or 8. Finally, a thin layer Qiu is provided above the thin layer 4. Each of the thin layers 18, 20 and 22 does not contain functional particles, and 15 contains fibers of different types and types as phases Either thin layers or each other. The resulting multilayer structure includes a thin layer of fibers and functional particles that alternate. The lines of these functional particles are substantially surrounded by fibers. The side edges of the multilayer structure of Figure 3 are optional To provide an edge seal, as described in PCT application wo 00 / 7179〇 (this publication is hereby incorporated by reference). The description of the multilayer structure in Figure 3 is intended to broaden the thin particles with three functional layers However, the structure may include as few as two layers of this thin layer, or may be suitable for special Many thin layers are used. In a preferred embodiment, six of these thin layers can be provided. 14 200302112 发明, Description of the Invention The multilayer structure of Figure 3 itself can include other thin layers in a single multilayer structure to provide You 丨 '1 /, for example, a structure with specific liquid collection, distribution and storage capabilities. Line 5 " The line of the thin layer of functional particles in the picture is not parallel to the MD or Y direction of the thin layer And continuously extend. However, the lanes or areas (hereinafter collectively referred to as "lanes") may be arranged in other methods suitable for the present invention. For example, 'the lanes may remain parallel, but may be periodically The particles are provided to provide a line segment with a gap between the segments, such as 10 is not shown in Fig. 7. Furthermore, the lines can be laid in an s shape in the longitudinal direction, and the lines have S Shaped spaces, as shown in Figure 4. Furthermore, the lines can be hourglass shaped, as shown in Figure 5. Similarly, other patterns, such as circles (Figure 6) can be used. However, it is important The thin layer of each functional particle includes Lines with functional particles and spaces 15 without functional particles, and these patterns must be arranged so that the lines or areas of the thin layer of the first functional particle will not be superimposed on the second next B ratio Connected functional particles have a thin layer of channels or domains. Notwithstanding the foregoing, a small percentage (less than 15%) of the area of the channels or areas overprinted on each other is also considered to satisfy this definition. The preferred coverage of the thin layer of functional particles is 20 depending on the application and thickness, density, and other parameters of the particles. It is generally preferred that the line of the thin layer covers the thin layer by at least 30% (preferably It is 40% and preferably 50%) of the XY area. Functional particles The functional particles are intended to accept particles, flakes, powders, fine particles 15 200302112 玖, invention description or the like. The particles may include any powder or other particles having a particle diameter of up to 3,000 microns (μ). The particle area may include a particle loading of 2 to 2,000 gsm (grams per square meter), more preferably 2 to 1,000 claws, even more preferably 10 to 600 gsm, and most It is preferably 100 to 25 gsm. These particles may be superabsorbent polymers ("SAP,") or other functional materials. Other suitable particles include odor control agents (eg, zeolite or calcium carbonate), perfumes, detergents, and the like. Super The absorbent polymer is a water-soluble compound that has been cross-linked to make it insoluble in water. It is still able to swell to at least about 15 times its own weight in a physiological saline solution. These superabsorbents The body material can be generally divided into a kind of 4, 'and 5 in other words, it is a powder graft copolymer, a cross-linked carboxymethyl cellulose derivative, and a modified hydrophilic polyacrylate. Absorbing polymers Examples include hydrolyzed starch-acrylonitrile graft co-polymers, 15 saponified acrylate-vinyl co-polymers, modified cross-linked polyvinyl alcohol, neutralized cross-linked polypropylene Folic acid, cross-linked polypropionate, and carboxylated cellulose. Preferred superabsorbent materials form hydrogels after absorbing fluids. The superabsorbent polymer material has a relatively high gel volume And quite high gel strength (As can be measured by the shear modulus of the hydrogel). This preferred material also contains a relatively low degree of polymeric material (which can be extracted by contact with synthetic urine). Superabsorbent polymer It is quite well known and commercially available. An example-is under the name swollen_ (Hochst_Cdanese), Perthsmouth, VA) 16 200302112 发明, Description of the invention, Starch-grafted polyacrylate hydrogels. Other commercially available superabsorbent polymers are available under the trademark Sanwet (Sanyou Casio Giobassigi (Sanyo Kasei Kogyo Kabushiki), Japan), Sumika Gel and SA60S (Sumitomo Kagaku Kabushiki Haishi, Japan), Pfeiffer (Favor) (Stockhausen, Garyville, LA), Kolon GS3500 Super Absorbent Polymer Granules, Kulon, Korea; and ASAP Series (Chemdal ), Those sold under Aberdeen, MS). Polymers of superabsorbent particles 10 detailed description of special interest 4,102,340 and Re in the United States. 32,649. Examples of suitable SAPs are surface-crosslinked acrylic-based powders such as Starkhausen 93 50 or SX FAM 70 (Greensboro, NC). Fibers Fibers suitable for use in the structure of the present invention may include cellulose or synthetic fibers or mixtures thereof. The best is lignocellulose. Also preferred are cotton fluff pulp, chemically modified cellulose (such as cross-linked cellulose fibers), and highly purified cellulose fibers (such as Buckeye HPF (each commercially available) From Buckeye Technologies Inc. ), Memphis, Tennessee))). Staple fiber 20-dimensional can be mixed with synthetic fibers, such as polyester (such as PET), nylon, polyethylene, or polypropylene. The fiber-containing sheet may also include a thermoplastic bonding material, which may be mixed with cellulose or synthetic fibers. Suitable thermoplastic bonding materials include thermoplastic fibers, such as bicomponent thermoplastic fibers ("bico"). Better Thermoplastic Adhesion 17 2 0 2 202 1, Description of the Invention Knotted fibers provide enhanced adhesion to a wide range of materials, including synthetic and natural fibers, particles, and synthetic and natural carrier flakes. Typical thermoplastic bicomponent fibers are Celbond Type 255 bicomponent fibers (from Hurst-Cyrenes). 5 Other suitable thermoplastic fibers include polypropylenes, polyesters, refractory and other olefins or modifications thereof. The preferred thermoplastic fiber is Fiber-Visions type AL-adhesive-C bicomponent fiber, which includes a polypropylene core and an activated copolyolefin protective layer. When the matrix fibers are cellulose or synthetic fibers (or a mixture thereof), each of the thin layers arranged between the thin layers of functional particles may preferably contain about 1 to 20 gsm of synthetic fiber cellulose. The thermoplastic adhesive material may be present in the thin layer in an amount of 2 to 50% by weight based on the total weight of the thin layer, more preferably 3 to 20%, and most preferably about 10%. Optimally, the thin layer between the thin layers of the functional particle contains 3. 0gsm short fiber pulp and l. Ogsm's two component. 15 Adhesives In addition to the thermoplastic fibers discussed above, other suitable adhesives which can be used in the structure of the present invention include those in liquid form or with a liquid carrier, including latex adhesives. Useful latex adhesives include copolymers of vinyl acetate and acrylates, ethylene vinyl acetate copolymers, styrene-butyric acid butyrate copolymers and polyacrylonitrile, and Air Products Co., Ltd. (Air Products Inc. ) Are sold, for example, under the trade names Airbone, Airflex and Vinac, Goodrich Chemical Co. ) 'S Hycar and Geon, and H. B. Fullai Company's Fulaiex 18 200302112 玖, invention description. Furthermore, the spotting agent may be a non-latex adhesive, such as epichlorohydrin and the like. ~ The present invention considers two separate adhesive applications. In a first application, an adhesive is applied to the structure so as to be in contact with only areas or lines that are free of particles / grains (which are adjacent to areas or lines containing particles disposed between the first and second layers). The adhesive can be applied in the form of a spray, foam or mist. In a preferred embodiment, the adhesive can be diluted to contain 3 to 25% solids, more preferably 6 to 12% solids, and most preferably 100/0. For a highly compacted small-hole environment (10 liters into a ceremonial seal) acting in a particle-free region, the diluted adhesive may ideally have a relatively high solid content (such as 10%). This environment produces rapid capillary action, and the high solids content reduces the adhesive's drift to other areas of the mesh fabric. The second application of the adhesive includes applying the adhesive in the form of foam, spray or mist to the entire surface of the structure on the substrate (as an "overall adhesive") to reduce dust falling on the structure. On the outside and inside. In a preferred embodiment, the whole adhesive is diluted to contain 1 to 20% solids, more preferably 2 to 100/0 solids, and even more preferably 2 to 4 〇 / 〇 solids, and most preferably about 3. 5% solids. Because the adhesive will penetrate to reduce dust out and fix the functional particles, it will not provide a significant contribution to the structural integrity of the mesh fabric. The use of two adhesive applications allows the hardness of the sealed area and the hardness of the unsealed area to be controlled independently. The hardness of any area can be controlled by selecting the type of adhesive, the solid content, and the amount of adhesive applied to each area. 19 200302112 玖, description of the invention. This satisfies the need for sufficient seal strength for transportation and sufficient flexibility to maintain user comfort. MJt can use thermally activated fibers or other binders to properly fix the fibers of the present invention to provide integration to the structure. In some embodiments, a thermoplastic bonding material is used and a seal is formed when the structure is densified or densified by dust or heat and heat. The seal can be further enhanced by subsequent hardening in a hardening oven. It is preferred to use thermoplastic fibers as the binder fibers and heat as the hardener. Heat may be applied to harden the fibers at the end of the air-sinking process or periodically during different stages of the process. In another embodiment, the seal may be provided by applying a liquid adhesive (or an adhesive in a liquid carrier) after compacting or densifying the mesh fabric. In this specific embodiment, the target 15 of the adhesive is to be in contact with the non-granular area and avoid soil or soil in the granular area. The adhesive will suck into the dense area and form a seal after drying and hardening. Furthermore, in these embodiments, the upper and lower layers may optionally include a thermoplastic bonding material. In another specific embodiment, the denseness can be formed by coating only a liquid adhesive (or an adhesive in a liquid carrier) only in the non-particle area ^ 'wherein the adhesive will be sucked into the already dense And a strong seal is formed after drying and hardening without densifying the particle-free area. In a preferred embodiment, the particle-free area can be compacted or densified, followed by coating-adhesive (the goal is to contact the particle-free area 20 200302112 发明, description of the invention and avoiding the particle area) A seal is formed. The adhesive will suck into the densified area and form a seal after drying and hardening. In these preferred embodiments, 'the upper and lower thin layers each comprise a thermoplastic bonding material' which enhances the seal after densification and hardening. The heat seal is substantially free of functional particles and the resulting seal is stronger than a seal having particles at the sealing interface. When the structure of the present invention is subjected to liquid damage, there are substantially no particles (such as SAp particles) in the sealed area (which swells and interrupts the integrity of the seal). 10 In some embodiments of the invention, the object is an absorbent object. The fibrous structure with improved particle loadability can be transported in the form of a drum-like commodity (or in other packaging forms, such as hanging), and can be used particularly as an absorbent core for disposable absorbent objects, such as diapers, adults Urinary incontinence, short tight pants, and feminine tampons. The air sedimentation of the structure of the main invention, 15 20 The structure of the rabbit is preferably prepared into an air sedimentation mesh fabric. The air-settling mesh fabric can typically be prepared by decomposing or maintaining the cellulose pulp or flakes (typically by key milling) to provide individualized fibers. Then, the individualized fibers are conveyed by air to a forming head on an air-settling mesh forming machine. Some manufacturers have machines for forming the air-settling mesh fabrics, including Fibretech from Denmark and Dan Web (also Denmark). The shape-forming sg is red ^ The shape-shaped one includes a rotating or stirring drum (usually a bearing raceway structure), which can be used to maintain fiber separation until the fibers are pulled by a vacuum device to a condensation drum with a small hole or There are small holes on the forming conveyor (or into the 2003 21021 玖, invention description shape line). Other fibers, such as synthetic thermoplastic fibers, can also be introduced into the forming head via a fiber feed system that includes a fiber opener, a feed unit, and an air conveyor. If multiple layers (such as distribution and acquisition layers) are desired, a separate forming head can be provided for each type of layer. 5 In a preferred embodiment, the material and structure of the present invention comprises a carrier tissue. A compaction roller may optionally be used before introducing the particle area to eliminate the need for the tissue. As contemplated by the present invention, one or more forming heads of the air-settling mesh-forming machine can distribute the desired fibers to the lower layer of the absorbent structure. 10 Then, SAP fine particles or other particles are applied to the upper surface of the mesh fabric. The particles have been coated in a line in the machine direction, and there are no particle areas or lines in between. Other particles include odor control agents (e.g., zeolite or calcium carbonate), perfumes, detergents and the like. A second layer is then formed over the top of the lower layer of the coated particles. Then another thin layer of SAP fine particles or other particles is applied to the upper surface in the line. The lines are coated so that the fine particles do not overlap with the fine particles in the thin layer containing particles below. Subsequently, alternating fibers and fine-grained layers can be added as desired. Figure 6 depicts a 20 process for making a fibrous mesh fabric according to the present invention. Optionally, a carrier tissue pool can be released from the supply roll. The thin fabric 20a is rolled to the screen 18. The thin fabric may additionally be used as a carrier for an absorbent object or as the lower thin layer 16. As contemplated by the present invention, the forming heads 24 of the air sinking, loop-like fabric forming machine may distribute the desired fibers to form the lower layer 16 of the absorbent structure. Cellulose fibers can be obtained by disintegrating or defibrating 22 200302112 玖, description of the invention, fiber, hydrazone sheet, or family flakes (typically by key milling) to provide individualized fibers. The individualized fiber air is then delivered to a forming head on an air-settling mesh fabric forming machine. The cellulose fiber and the optional thermoplastic fiber can be added to the 5 cellulose thin fabric 20a through the forming head µ. Some manufacturers have machines for making the air-settling mesh fabrics, including M & J Fibritek of Denmark and Don Weber (also Denmark). The forming head includes a rotating drum or a caster, usually a bearing raceway structure, which is provided to maintain fiber separation until the fibers are pulled by a vacuum device to a small hole condensation 10 drum or a small hole forming conveyor Or forming line). For example, in a machine made by Café Britek, the forming head contains a sifter-rotary mixer. Other fibers, such as synthetic thermoplastic fibers, can also be introduced into the forming head via a fiber feed system (which includes a fiber opener, a feed cell, and an air conveyor). If multiple thin layers are desired, such as a 15-distribution thin layer and a synthetic fiber collection thin layer, multiple forming heads (one for each type of thin layer) are available. In a clip formed by a pair of calender rolls 26, the fibers are selectively compressed to a desired thickness and density. The lower layer 16 can be compacted at this point in the manufacturing process to close the holes of the mesh fabric (if the particles are fine), and 20 can prevent spillage to the forming line. Particles can be applied to the lower thin layer 16 using a particle applicator 28. Therefore, SAP fine particles or other particles may be applied to the upper surface of the lower thin layer 16. Now referring to FIG. 7, the particles can be coated in a plurality of lanes 6 in the machine direction, in which no-particle area or lane 8 is located between the granules. 23 200302112 发明, description of the invention π e ice Retreat from Hungary, don't send the area of the particles. Other human tablets. Suitable particles include oxygen flavor control agents (for example, zeolite or calcium carbonate), flavors, scale inhibitors, and the like. The second thin layer of fibers 18 may be coated with cellulosic fibers by a forming head 34, i.e., 5H, and optionally coated with thermoplastic fibers (such as bicomponent fibers). Several layers can be added continuously on top of the second layer. After applying the second thin layer, the mesh fabric can pass under another particle applicator 28 (not shown) to apply another thin layer of particles, and then apply another thin layer through another forming head 34 Fiber (not shown). In this method, the mesh fabric can build up a desired number of alternating layers of fibers and particles. A series of ovens are used in the process of the invention to dry, harden or heat bond. The air-settling mesh fabric 23 is heated in an oven 50 to a temperature range of 125 to ° C. When using thermoplastic fibers (preferably 15-dimensional bicomponent fibers), the hardening temperature and residence time must be sufficient to melt the fibers and cause sticking. At 52, an overall adhesive is applied to the air-settling mesh fabric 23. This adhesive can be applied by spray, foam, or mist ' and can be applied to reduce dust from falling onto the surface of the structure. The air-settling mesh fabric 23 is heated in the second oven 54 to a temperature range of 125 20 to 180 ° C. The air-settling mesh fabric 23 can be treated in a pressure range of 0.1 to 10 psi, preferably 15 psi. As a result of this, a heat seal can be formed between the thermoplastic material and the fibers of the upper and lower layers. The heat seal is substantially free of particles (especially SAPs) and can destroy the heat seal after exposure to moisture. Then, this finished mesh weave 24 200302112 Rose, invention description The object is rolled into a roller for future use. The continuous web of fibrous mesh can be torn or cut into cutting units to form individual absorbent objects, which are not depicted in this figure. It is possible to selectively tear or punch 5 holes at the heat seal of the finished mesh fabric to produce a narrow gap core material with heat seals along the two edges. The heat seal to be ripped must be wide enough to provide two effective seals after tearing. In other specific embodiments, different other layer coatings of other types and fiber amounts may be included above or below the upper and lower layer structures of the present invention. For example, the absorbent object may include a liquid-permeable top sheet and a liquid-impervious back sheet. Typical absorbent objects that can be formed from the absorbent core of the present invention include diapers, feminine tampons, and adult incontinence products. The specific embodiment of the code of the present invention is manufactured on Dang Weibo, an air settling pilot 15 with three forming heads (which has been added to the between-the-head SAP feed system). Examples 1 and 2 , 4 and 5. To obtain more than three layers, the structure can be made by passing the mesh fabric through the forming process more than once. On each pass, the material is slightly pressurized at the end of the wire. On the last pass, ’adjust the final thickness. With the aid of the dividing box, the SAp powder is placed in individual lanes, as depicted graphically in Figure 9, which covers approximately -half the area of the air sedimentation forming line. In the following example, the width of the divider is 1.27 cm and the width of the space between the dividers is 2.7 cm. The original materials used in the examples are Fuli staple fiber (Fluff) (FF) '-a kind of southern soft wood bleached kraft paper pulp, Pak Cute Technology Limited 25 200302112 玖, Invention Description Company, T-255 polyolefin double Component fiber, 28 dpf, K0Sa; 3024 cellulose carrier tissue, 18gsm, CeUu Tissue Co. ); T-224 polyester fiber, 15dpfx6 mm, K〇Sa; Sumitor touch SA60S super absorbent polymer fine particles, Sumituo touch, Japan, Feffer 8805 super absorbent polymer fine particles, Di Degussa, USA, Kulon GS3500 superabsorbent polymer granules, Kulon, Korea and Airflex 124 latex, AirProduct Chemicals. The materials of Examples 1, 2, 4 and 5 had several layers produced by secondary passing through the three-head air sedimentation machine. First, a layer 1 10 was made on a cellulose carrier, and then the first SAP feed was placed in the layer. In the lane, followed by layer 2 and then the second SAP is fed in the lane, where the lane from the second SAp feeder SAP will cross the machine direction with the first The positions of the lanes SAP are complementary, so looking at the material from the top along the z dimension (which is perpendicular to the machine direction and the cross machine direction), the SAP lanes from consecutive 15 feeds will not be overprinted together. The following is provided in reverse order to make the compositions of Examples 1, 2, 4, and 5. For a particular SAP feed, the SAP amount in grams per square meter (gsm) is the overall basis weight of the feed. Because the SAp is placed in the lane, the amount of SAP continuous locations in the machine direction of the parent fork can be changed from zero or about zero (20 between SAP lanes) to about 100 percent (in those lanes) .

As the force required to bend the sheet increases, the flexibility of the thin 20 sheet decreases. Flexibility can be measured by the following procedure using a Gurley tester (model 4171, Gurley Precision Instruments, Troy, NY). 1. Cut the sample to 1 inch x 3.25 inches as accurately as possible. If there are 30 302112 玖, invention description clear machine direction and cross direction, cut a sample in each direction and test each sample. 2. Install the conventional clamps as shown in Figure 3 above the original clamps provided by the Gurley test machine, and tighten the small upper thumbscrews to ensure safety 5 (see Figure 2, which illustrates Known for clamps with higher basis weight and bulky flakes). The conventional clamp has been designed in a manner that does not change the thickness of the test material, where the material is embedded in the clamp. If clamped, the result is. If the thickness has changed, then the properties of the structure will change and the results obtained using the Gurley tester have been affected. In this method, the sweetness ° of Figure 3 is used to eliminate this unwanted effect. 3. Open the adjustable plate of the known boat by loosening the long chin screws. The sample is placed in the sweetness by sliding the sample up until it only touches the original pinch. At this point, a 2.0-inch sample should be contained in a conventional clamp. 15 4. Adjust the known clamp south by loosening the height adjustment screw on the original clamp. Adjust the height so that there is a gap between the point where the sample exits the conventional lost cone and the point where the distant sample will contact the lever arm. 20.5. The sample of the remaining 0.25 inch will extend to the page 4 below the lever, and the lever arm will not move. Depress the motor button to move the sample: toward the cup | Keep pressing the motor button until the sample passes the lever arm. It is said that A becomes this 4 ', and pay attention to the highest number that reaches that level. Repeat this in the opposite direction. • Average the two values obtained. In the conversion diagram on the device, 31 200302112 has been issued. The invention description is now χ1 · 5 in the case of 1 center. For a long sample, the factor depends on the weight used. It depends on the distance. Use the conventional clamp to measure the sample of 4 (1) 忖 3 · 25 British pair and test it without using the conventional clamp;! · 〇 英 忖 χ1 · 5 忖The samples match. Without the conventional 5-clamp, there is a sample of 0.25 inches in the original clamp, which extends 0.25 inches below the top of the lever arm and 1 inch between this distance. For the sweetness of sweetness, the same amount of -25 忖 is used in the conventional clip; the other i · 75 · in the conventional clamp is appropriate to stabilize the thicker sample. Similarly, there is 0 • 25 inches extend to 4 below the top of the lever arm, and similarly 1 inch to 10 intervals. 7. Multiply the average reading at this level by the appropriate conversion factor found on the graph. The result is hardness Expressed in milligrams of force (mg). Here the flexibility (P) is defined according to the following formula: 15 ρ == 1〇6 / 9 · 81 * hardness. , ° Fruit, P here is 1 per cow (1 / N).

Ruler with millimeter scale. 36 200302112 发明, description of the invention Cylindrical container marked with a scale of one tenth of a milliliter. Procedure The 5 samples were assembled by placing an ASP-on plywood (cut into 10 cm x 20 cm) over one end of a plywood (cut into 10 cm x 40 cm) under the DSP. It should be noted that the polyester fiber layer of the ASP should face up and the thin fabric edge of the DSP should face down. The sample is placed in a test device by placing the sample on a plastic plate. The coating slurry material was placed over the sample. Insert the plastic damage tube into the foam. The foam block was placed on top of the sample; the 10-damage tube should be located above the plywood on the ASP. One black weight tablet and two gray weight tablets were placed over the foam block to obtain a load of 2.7 kPa (0.4 psi) on the sample. Figure 6 contains a schematic test setup. Set the timer to 20 minutes and place it next to the test device. 15 Hold the horse watch in one hand and the graduated cylinder containing 75 liters of saline solution in the other hand to prepare the sample for damage. Pour liquid into the plastic to damage the cylinder. Start pressing the watch when the liquid comes in contact with the sample. Aspirate the liquid from the graduated cylinder as quickly as possible. When the liquid is absorbed by the sample, the filament is stopped. The time it took for the sample to absorb the liquid was recorded, and 20 was taken as the acquisition time for the first lesion. Once the liquid has been absorbed by the sample, the 20-minute timer is pressed. Wait for 20 minutes. After the 20 minute waiting period, step w is repeated twice on the same sample to measure the acquisition time of the second and third lesions. After the third 20-minute waiting period, the timer was set to 5 minutes 37 hours, invention description clock, and placed next to the test device. Weigh a stack of 10 sheets of S-22 blotting paper. Record the weight. The weight was removed from above the sample, the foam block, and the damaged cylinder. The stack of paper was placed on the sample. The foam and weights replaced on the sample. Start pressing the 5-minute timer. At the end of 5 minutes, the weight and foam were removed. Weigh the stack of paper again. Record this second (wet) weight. The rewetting (expressed in grams) is the difference between the clear weight of the paper and the dry weight of the paper. Find the furthest position of the liquid sucked into one end of the sample, and draw a line across the width of the sample at this position. Repeat the same thing at the other end of the sample. Measure the distance (in centimeters) between the two lines. Record this number as the capillary action distance. The results of this core were 49.2 seconds for the first damage collection, 104 seconds for the second and 129 seconds for the third.耋 mi, · Absorptive core thickness U3 亳 m, flexible 1351 / N This core was made using the procedure of Example 8 except that ASp was the material of Example 6 and SAP was the material of Example 5.

This improvement can be illustrated, but not limited, by the examples summarized in Table 3. Based on these results, when the folded sample is a folded structure (see Figure 11), we can see that the performance of the folded structure is better than the unfolded sample with the same overall basis weight. These improvements have significantly shorter acquisition times and also lower rewetting values.

The edge of each side is folded more than about 4 · 3 cm. The layer is divided into three parts (4.3 cm folded, 4.3 cm unfolded open, 4.3 cm folded), and the total width is about 13 cm. (See Folding and 5 Unfolded Faces, Figure 11) 3. The effect of treated Flystad® (TFF) on capacity and collection Use Molly Kelgar from Hartmann (MoliCare Plus) AI diapers were used as control products. The absorbent is in three layers (a shrunk fiber acquisition layer, an SAP short fiber layer, and a short fiber back layer against the multi-back sheet) 10. The diapers were disassembled by carefully peeling the short fiber back layer from the SAP short fiber layer. Then, the SAP staple fiber layer was peeled from the coating slurry and the shrunk fibers. Then, the air-settling core was placed on the short fiber backing layer and covered with the crimped fiber and the top sheet. The crimped fibers are not removed from the top sheet. One of the insert cores (i.e., Example u) contains Fryst 15 fibers as a cellulose fiber component, and the other contains the treated Fly staple fibers. The air settlement width of the obtained absorption system i inserted was 13 cm and its length was 66 cm. The results in Table 4 illustrate the performance of the treated Flit® in absorbent system 1 (which consists of the top sheet, a shrunk fiber layer, an air settling insert, short 20 fibers, and a multi-back sheet). On the impact. As can be seen from the data, the collection of Example 15 containing treated Flystad® was significantly faster than the collection of Example 11 containing Flystad φ. Samples with sw_16 fiber have also improved capacity (exceeding samples with FF). 45 200302112 发明, Description of invention Table 4 BW from the example, SAP fiber capacity® is only 0.4 pieces / square inch of air sediment insert absorption system 1 liquid intake time, second core material gsm type% 13 cm x 40.6 cm g / Gram first second third third 11 253 SXM 70 75 FF 218 (SD3.8) 16.3 (SD0.45) 94 287 412 15 252 SXM 70 75 TFF 248 (SD2.5) 18.7 (SD 0.15) 75 239 360 4. The effect of treated Flystad® on the liquid uptake of folded high SAP air sediment. 5 A Morikel Super AI diaper from Hartman (as described above) was used as a control product. In this example, the air-settling core is first C-folded as shown in Fig. 11, and then it is placed on the back of the staple fiber and covered with the shrunk fibers and the top sheet. The crimped fibers are not removed from the top sheet. One of the insert cores (which is the C-fold of Example 11) contains Frylon staple fiber 10 as the cellulosic fiber component, while the other (Example 15) contains treated Fleece®. The air settling insert is 13 cm wide and 66 cm long. The results in Table 5 clarify the treated Flye staples and folds in the absorbent system 2 (which consists of the top sheet, the shrunk fiber layer, the air settling insert, the staple fiber and the multi-back sheet Composition). As can be seen from the information, the acquisition of C-folded Example 15 containing the treated Flystam was significantly faster than the acquisition of Example 11 containing the Flystad. Samples containing treated Flystad® fibers have also improved capacity (more than samples containing Flystad®). 46 20 200302112 发明, Description of the invention Table 5 The core material from the example, the liquid intake time of the SAP fiber absorption system 2, seconds C-finger stack (see Figure 11) Type% First time Second time Third time 11 SXM 70 75 FF 64 161 265 15 SXM 70 75 TFF 50 119 190 The effect of glued acquisition plywood and treated Flystad® on the liquid uptake of folded high SAP air sediment in the entire absorption system 5 To make one Attach the acquisition pad, disassemble some of the Molikeer Super Diapers and remove the acquisition pad. The removed shrunken fibers were then used to make an air-settling handsheet using a laboratory pad blowing device, and 8% KoSa T-255, 2.8dpf fibers were added. The pad was hardened at 160 ° C for 10 minutes. These acquisition pads have a basis weight of about 159 gsm and a thickness of about 3.8 mm 10. The basis weight of the unbonded acquisition layer of the crimped fibers in the original diapers was about 154 gsm and its thickness was about 2.0 mm. They were added to this Molikale super diaper shell together with Example 15. Example 15 is a C-folded structure shown in FIG. The results shown in Table 6 indicate that the C-folded air-settling inserts (including treated Flystad® fibers) and the absorbent system 2 with a bonded 15 acquisition layer have better acquisition performance than the original diaper. 47 200302112 发明 、 Explanation of invention Table 6 Examples of high SAP air sedimentation components Crumpled fiber acquisition plywood overall mass absorption system, absorption system 2 in high SAP air sediment 2 (see Figure 3) Liquid intake time, seconds without Folded / C-folded gram fiber for the first time the second time for the third time 14 unfolded and unbonded 72 FF 67 197 310 11 C-fingers (see Figure 1) unbonded 73 FF 64 161 265 15 C-folded (see Figure 1) Unbonded 73 TFF 50 119 190 15 C-folded (see Figure 1) Bonded 73 TFF 25 61 100 Unbonded control Unbonded 114-53 108 144 Examples 16 to 18 All examples contain 2 heads The 3-head air sedimentation collar 5 of the SAP feed system is manufactured on the Weber machine. The SAP powder is placed in individual lanes along the machine direction (MD). These lanes can be formed with the aid of the division box described in Figure 9 of the original application. These dividing boxes are used to mask a 50% area of an air sedimentation forming line. The width of the divider is 1.27 cm and the width of the gap between the dividers is 1.27 cm. This division box can be used to distribute the same amount of SAP over half of the area, resulting in SAP stripes with twice the overall basis weight. The structures of Examples 17 and 18 include a thicker layer of bonded cellulose fibers for improving capillary action. The SAP can be fed to an air settling forming line using any conventional equipment containing a dividing box as shown in FIG.
