水性之所謂立體褶撊之防漏用袖口等構成。用於此等衛生 材料之原材料，因薄而具強度，與皮膚直接接觸具柔軟觸 感，以及生產力、價格等，大多使用非織物。 衛生材料之一的拋棄型尿布之頂片，因係與皮膚直接 接觸之材料，連同柔軟觸感，有尿等瞬間透過，少回濕， 多次排尿可重複透過之耐久透液性能等之要求。 目前係使用複合短纖維等之蓬鬆纖維，以熱風或部份 熱壓熔合而接合者。但以熱風接合之非織物雖蓬鬆具緩衝

)基本構造如第1圖之示 意圖。如第1圖（I )、 （ m )，非織物構造係以（a ) 部份熱壓熔合纖維域軋紋圖案（以下或簡稱部份熱熔合部 )及（B )非結合纖維之局度密域所成之軋紋凸或凹圖案 固疋。第1圖之（A)、 （B)圖案係示意圖案，實際圖 案可係形狀、間距均不同於（A )、 ( b )。並且，（A ) 及（B )各圖案係各獨立於非織物構造正反面連續或非連 續配置。非織物構造更含接觸上述（A )及/或（B )之 (C ) ’非結合纖維之低密度域。在此，（A )部份熱壓 (5) (5)200406178 熔合纖維域軋紋圖案係經熱軋紋而成，（B )非結合纖維 之高密度域所成軋紋凸或凹圖案，係低溫下或於纖維不熔 合之溫度下所形成之軋紋圖案，非織物之正面（第一面） 及反面（第二面）有反向成形之圖案（參照第1圖（m) 、第2至4圖）。第7圖示本發明紡黏系非織物之一具體 例。第7圖（I )可觀察到形成（A )、 （ B )及（C )之 軋紋圖案的非織物構造。第8圖（I )係含熔吹纖維網之 層合的本發明紡黏系非織物之例，如同第7圖之例，可觀 察到形成（A ) 、 （ B )、 （ C )圖案之非織物構造。由以 上第7、8圖應可明白瞭解上述含（A)、 （B)及（C) 之本發明非織物固定構造之具體樣態。 本發明之紡黏系非織物的蓬鬆率係以，非織物構造之 非結合纖維低密度域所占非織物之厚度（a )對非織物之 含凸軋紋圖案面的非織物厚度（b )之比，亦即由下式算 出的値表之（參照第1圖（ΙΠ ))。 蓬鬆率（％ ) = ( b / a ) X 1 0 0 在此，非結合纖維低密度域厚度（a )係低溫下凹凸軋紋 加工前之厚度，因此蓬鬆率亦可利用凹凸加工前後之厚度 差算出。蓬鬆率係決定非織物柔軟性之重要因素，顯示低 溫下之凹凸加工於非織物構造起搓揉作用。 本發明之紡黏系非織物可使親水化劑主要含於非，結$ 纖維之高密度域（B )，以將非織物改質爲同時滿足衛生 材料所需之蓬鬆、柔軟、透水、回濕四特性。 以下詳細說明本發明。 -8 - (6) (6)200406178 構成本發明之紡黏系非織物的纖維係，聚乙烯、聚丙 烯或其共聚物等之聚烯烴系纖維，因纖維本身吸水性低、 回濕性上良好而爲較佳，聚對酞酸乙二醇酯、聚對酞酸丁 二醇酯、聚對酞酸丙二醇酯（PTT )或其共聚物等聚酯系 纖維因強度、乾爽感而爲較佳，尼龍6、66、610、12或 其共聚物等聚酰胺系纖維可製成潤濕、柔軟之非織物而爲 較佳。必要時亦可用此等之複合纖維、混合纖維或更混合 以具其它特殊功能之纖維。 非織物因須具足以對應表面尿濕時，使用時身體動作 之強度，並由於生產力，係以將連續長纖（絲）製成網， 將之接合成形之紡黏法非織物爲佳。紡黏法非織物因纖維 長，具實用上之強度，透氣性優，而且不同於濕式法或乾 式法者，無油劑處理等之施行纖維直接片化，可活用纖維 特有之拒水性等性質。 非織物構造內之纖維網的接合，爲使非織物具強度、 柔軟性及纖維本身之觸感，係以部份熱壓熔合法接合爲佳 。部份熱壓熔合時熱壓熔合面積率基於強度保持、柔軟性 等係以5至4 0 %爲佳，5至2 5 %更佳。部份熱壓熔合除超 音波熔合機等以外，可使纖維網通過加熱至構成纖維之熔 點以下的熱軋紋輥間等爲之，藉此，非織物構造正反面一 體化，於非織物全面散布例如針點狀、矩形等凹凸模樣。 當然，該熱壓熔合部係經壓合成膜狀，其周圍之纖維則具 所用纖維特有之觸感。 僅由該部份熱壓熔合而成之非織物，隨纖維構造、軋 -9- (7) (7)200406178 紋形狀及配置，其厚度起變化，但通常的圓截面纖維之無 捲縮纖維厚度不可謂大。尤以紡黏法製成之通常的網，其 形成時纖維亦係平面排列’蓬鬆度不高。 而部份熱壓熔合係以熱及壓力作部份黏合，於構成纖 維之熔點以下的溫度於軋紋圖案部份施加壓力而形成。餘 留有不同於在熔點溫度以上熔合成膜者之纖維形狀而黏合 成「膜狀」部份，係有別於非結合性凹凸加工所形成之高 密度部份之部份熱壓熔合。 如上，本發明之紡黏系非織物係藉部份熱壓熔合部正 反面一體化之非織物，係形成一面的熱壓熔合部圖案不同 ’具有非結合纖維之高密度域的凹部，而反面有非結合纖 維高密度域之凸部的非織物構造，非織物係以點狀分布之 部份熱壓熔合部使正反面一體化，其它部份係非結合纖維 之高密度域的凸或凹軋紋圖案及非結合纖維之低密度域等 纖維密度不同之二域所成，各受到低溫軋紋成形加工之搓 揉作用，纖維本身形成容易移動之構造，故成爲觸感柔軟 、逢鬆之非織物構造。 非結合纖維之高密度域係第I至3圖中B所示之區域 ’乃纖維間未經熔合或黏合之區域，係經凹凸加工用軋紋 輥之凹凸部的壓縮，纖維被壓縮而密集之高密度纖維區域 ’例如以纖維體積分率表之則在15至35%之範圍。而本 發明中’非結合纖維之高密度域面積率係在5至5 0%，5 至25 %更佳。在此，部份熱壓熔合部之計算係由經熱壓熔 合之軋紋圖案的形狀算出。試樣非織物以顯微鏡擴大，由 -10- (8) (8)200406178 互相熔合之膜狀部份之輪廓，測定其大小、間距，求出其 面積’算出對試樣全體面積之面積率。 非結合纖維之低密度域係第1圖c所示之區域，纖維 未經熔合或黏合，相當於未經凹凸加工用軋紋輥之壓縮的 部份’較之非結合纖維之高密度域，纖維並未密集，大致 係具有凹凸加工前之纖維集合密度的區域。因此，該低密 度域之纖維蓬鬆，具移動自由度，有纖維原來之柔軟觸感 。例如’非結合纖維之低密度域纖維體積分率係在5至 1 5 %之範圍。非結合纖維之高密度域面積係找出壓成軋紋 之纖維高密度域內構成纖維經壓潰部份變形之軌跡，求出 其面積’算出對試樣全體面積之面積率。非結合纖維之高 密度域的纖維形狀者，係僅止於構成纖維可見壓陷，或亦 包含少有變形之纖維。 非結合纖維之高密度域厚度薄，纖維密集，經親水化 劑處理者因親水化劑多存在於高密度域，透液性良好，外 表面平滑，有滑溜柔軟之觸感。 非結合性之低密度域比高密度域厚，纖維集合密度低 ，柔軟蓬鬆，透液性良好，對液之回濕具阻障作用，液體 回濕性（Wet Back )上良好。 茲藉第1至3圖之剖視圖說明上述作用。第1至3圖 係有助於瞭解本發明非織物之構造特徵的示意圖。 (A )部份熱壓熔合部係用以保持非織物全體之強度 的區域，有恰當的面積率。 (B )非結合性高密度域係B之區域’因具凸出非織 -11 - (9) (9)200406178 物表面之形狀，使非織物全體蓬鬆。又，使該B區域多含 親水化劑’即可大幅提升該部份之親水性’具提升通過該 B區域的透液性之作用。 (C )非結合性低密度域係C之區域，纖維自由度高 ’富柔軟性’可賦予柔軟觸感。又，c區域因蓬鬆對來自 吸收體之液具阻障作用，有改善回濕性之作用。 而@ β之邊界有使之易於彎曲之作用。如此，本發明 之特徵即’ （A)、 （Β)及（C)各區域各具上述作用， 於全體則有適於衛生材料之作用。 本發非織物係使用習知複合纖維，與以接合、熱風 處理等熔合而硬、不光滑之非織物全然不同。 本發明因於具自由度之纖維層賦予非結合性凹凸變形 ’可製成加以部份變形（延伸）之纖維層，故緩衝性良好 ，有施加荷重時不易壓縮之特性。因此，可謂係荷重下仍 蓬鬆，具多孔性，容易透液（透液速度快），一旦透過， 吸收液不易回濕之產品。 本發明非織物之凹凸變形係，與部份結合之結合部圖 案有部份不一致之任意形狀的凹或凸變形，凹、凸部之形 狀、大小、深度與結合圖案相關，於柔軟效果具重要性。 凹、凸部之形狀可係例如直線、曲線、方、圓、梨皮 狀、其它連續相連配置，或非連續者，而基於柔軟效果， 凹、凸部涂度在0_2至5晕米，愈深效果愈大。又，非連 續凸部加壓面之大小係以0 · 1至5毫米，且凹、凸部之間 距以0.5至5毫米爲佳。 -12- (10) (10)200406178 第1圖係本發明之非織物的全體俯視構造示意圖。第 2、3圖示於非織物施以方形軋紋之例。第2、3圖示非結 合凹凸加工圖案之二例，圖中省略熱熔合部之圖案及其分 布。 例如，如第3圖，軋出凸部點狀分布之軋紋，即形成 高密度域非連續散布之凹部。又，如第2圖，軋出凸部連 續之軋紋，即於高密度域連續之狀態下，非軋押部凸出於 纖維層上。連續圖案之變形間距取決於其圖案，而以1至 5毫米爲佳，較佳凹部之大小係寬0 · 0 2至3毫米，線狀或 點線狀。 因設高密度域，蓬鬆效果下厚度加大，非織物構造之 蓬鬆度提升，荷重時厚度變化小。本發明人等發現，於非 織物賦予親水化劑，則非結合纖維之高密度域的親水化劑 濃度較高。 非織物的表觀厚度愈大愈柔軟，凹凸變形之間距及凹 部之大小係，除非厚度極大，可得極細纖維之觸感。 本發明非織物之蓬鬆率在100%以上，105至400%爲 佳，110至3 00%更佳，120至200%特佳。蓬鬆率大，則 荷重時厚度下降少，非織物之緩衝性提升。 第5、6圖例示本發明紡黏系非織物厚度對荷重之變 化。本發明之紡黏系非織物各荷重下厚度大而蓬鬆，可謂 荷重下壓縮特性良好。因此，本發明之紡黏系非織物，於 例如用作拋棄型尿布頂片時，隨時用時間之經過，厚度下 降少’尿布使用中呈現高度柔軟、蓬鬆特性之持續效果。 -13- (11) (11)200406178 而潮濕狀態下厚度下降亦少，對液體之由吸收體返回因蓬 鬆度大，可得良好效果。 紡黏非織物之凹，或非結合纖維之凸軋紋圖案之賦予 方法一般係，例如於表面有凹、凸或凹凸模樣，雙方正好 嵌合之輥間，其一之表面有凹、凸模樣之輥與撓性輥間軋 押，或於板間作處理，而特殊方法有，將布強制過度饋入 狹小間隙之輥間，形成小皺褶。 第4圖示，通過各表面有圓形凹凸模樣，二者正好嵌 合之二輥間，形成凹凸變形之例。 形成凹凸之條件，尤應注意者爲，處理時之溫度及施 加於非織物之壓力。處理溫度可係常溫，但必要時亦可升 溫塑化以易於成形，爲形態安定性，係升溫至纖維不起結 合或硬化之範圍作處理。例如，聚丙烯非織物者以3 0至 1 1 〇 °C之範圍爲佳。軋紋處理壓力隨溫度而異，但當然須 設定於能充分成形之壓力。而因作該成形受壓縮部份之纖 維截面起變形，由於該部份變形效果而更加柔軟，故以更 高壓處理亦係有用。當然，所採用之條件須不致使壓縮部 之纖維間起暫時固定或熱壓熔合。例如，聚丙烯非織物者 以20至150公斤/公分之範圍爲佳。 本發明之紡黏系非織物，形成於非織物單面之非結合 纖維的高密度域凹部，係以於反面形成有非結合性纖維之 凸部爲佳。例如，於單面形成連續凹部之高密度域時，以 於另一面形成高密度域凸部，成爲比其它區域隆起之凸狀 爲佳。此於使非織物全體之表現厚度在網厚以上，並使親 -14- (12) (12)200406178 水化劑存在於特定部位上具重要性。 本發明之紡黏系非織物的親水化劑處理通常可使用稀 釋親水化劑溶液，採用浸泡法、噴霧法、塗布法（輥塗機 、凹版塗布機、模口等）等已知方法。非織物在賦予親水 化劑之後，可藉熱風、熱輥等加以乾燥。 親水化處理中，先前賦予之高密度與其它部份的處理 劑附著分布應係不同。賦予處理劑液之際，表現上液多含 於纖維之低密度，所謂粗糙部份，隨非織物之乾燥，液移 往易乾部份。因此，非結合纖維高密度域應係隨非織物變 薄，依比率處理劑之附著變多，易於透液。又，一旦透過 之液因低密度域不易受壓縮而蓬鬆，離開吸收層而不易回 濕。如此，親水化劑主要含於非結合纖維之高密度域，可 得提升本發明紡黏系非織物特有之透液性，理想回濕性， 改善液流等之效果。 親水化處理之前，先施以電暈處理、電漿處理等以利 提升親水化程度。電暈處理等之處理可係印刷之前處理等 ，用於潤濕特性之改良等的一般處理，例如以高頻產生振 盪器等，於放電電極與處理輥之間饋以高頻電力使其放電 ，將非織物通過其間作處理。雖隨必要之潤濕性及處理條 件而異，處理面之表面張力係以使之爲37至40毫牛頓/ 米而設定放電條件爲佳。而施以電暈放電處理時因非織物 本身潤濕性不同，當然須調整親水化劑賦予量以得必要性 能。非織物表面張力在3 7至4 0毫牛頓/米範圍，則親水 化劑與非織物表面纖維之親和性明顯提升，親水化劑可低 -15- (13) (13)200406178 濃度、均勻賦予。本發明中，親水化劑係以於非結合纖維 域之凹凸加工後賦予爲佳，但於凹凸加工前爲之亦無特殊 問題。 經親水化劑處理之本發明紡黏系非織物衛生材料於使 用之際’當係係隨衛生材料所需之特性水準，選擇賦予之 性能及所用方法，而非織物正反面觸感之不同亦有關連。 开< 成之凹凸圖案的纖維局密度域雖不互相接合，但因已比 其餘牢固，用作尿布之頂片時，配置於非織物之不與皮膚 直接接觸的面之吸收體側，並於重視親水性之際，以高密 度域爲頂片之皮膚接觸面，均係較佳樣態。 本發明之結黏系非織物係使用於非織物構造層合有至 少一層的絲網’及至少一層的熔吹網之二層以上層合體之 樣態。 此時，用於非織物之纖維可係上述纖維原材料。必要 時亦可用此等之複合纖維、混合纖維，以及與具其它功能 之纖維的混合物。絲網間亦可於各層有不同原材料，絲網 與熔吹纖維網亦可具不同原材料。聚酯系纖維、聚酰胺系 纖維等與水具親和性之原材料，爲防水、拒水性，必要時 須以砂系、氟系或蜡系等防水劑、拒水劑作處理或添加以 作改良。 非織物須具能對應使用時身體之運動的強度，並爲生 產力’係以層合至少一層之絲網及至少一層之熔吹纖維網 的一層以上層合體’將之連續接合形成之非織物爲佳。該 層合構造可係僅只絲網與熔吹纖維網之層合，但爲彌補表 -16- (14) 200406178 面強度差的熔吹纖維網，通常係於絲網層間層合 維網層使用，亦可用有多數之各層者。亦可係各 層合者。 構成紡黏系非織物之絲係0 · 5至5分特，因 具實用上之強度，透氣性優，並與濕式法或乾式 ’不施以油劑處理等將纖維直接片化，可活用纖 拒水性等性質。 熔吹纖維網，如同例如特公昭5 6 -3 3 5 1號2 3,9 7 8,1 8 5，USP 3,82 5,3 8 0等之記載，所形成的 米之細纖維，覆蓋性優，例如，聚丙烯原材料更 防水效果。熔吹纖維網因其細纖維，結晶定向性 網易於接合。但是反之，單獨使用時雖接合強度

時等之特性，因熱而具紙般觸感，非織物全體硬如紙。該 部份熱壓熔合非織物，隨纖維構造、軋紋形狀、配置而其 厚度有別，但產生熔吹纖維網層特有之黏合效果，厚度變 薄，不蓬鬆。蓬鬆度之改良方法，如先前技術項下所示， 有開孔、賦形固定之方法，但並非如本發明之以層合至少 一層之絲網及至少一層之熔吹纖維網而成之二層以上層合 體，藉分散於表面之非連續部份熱壓熔合部使正反面一體 化之非織物，藉非結合性之凹凸變形得蓬鬆性或柔軟性， 亦不具熔吹纖維網層的黏合效果改善。 層合熔吹纖維網設計於非織物構造的本發明之要點係 ，對層合至少一層之絲網及至少一層之熔吹纖維網的二層 以上層合體，藉分散於表面之非連續部份熱壓熔合部正反 面一體化之非織物’更以軋紋加工等施以造成非結合凹凸 變形之處理，點狀分布的熱壓熔合部之纖維部份結合而正 反面一體化，其它部份之非結合性凹凸部之纖維，依然保 有纖維本身之柔軟觸感。 熔吹纖維網層無論黏合效果多大，不同於熱壓熔合部 ’可當作係扣合狀態，與經用以接合複合纖維之熱處理熔 合而硬、不滑溜者全然不同。又於具自由度之纖維賦予非 結合性凹凸變形力，施以部份變形（延伸）成爲纖維層， 可得充分之蓬鬆度。此乃施以荷重之際，與原纖維層不同 ’而具不易壓縮之特性。亦即，造成容易折曲之卷曲，可 得柔軟性、蓬鬆性（厚度）。

Description of the invention [Technical field to which the invention belongs] The present invention relates to a spunbond non-woven fabric, particularly a non-continuous pattern with a non-woven structure and a high-density domain of non-bonded fibers fused by partial heat pressing. The formed concave or convex embossed pattern is fixed and soft and fluffy spunbond non-woven fabric, disposable sanitary materials and improved non-woven fabrics suitable for disposable sanitary materials. [Previous technology] Sanitary materials used for diapers, physiological pads, etc. are generally made of a top sheet through which urine and discharge can pass, an absorbent body and a waterproof back sheet, and a so-called three-dimensional pleated waterproof sheet. Missing cuffs and other components. The raw materials used for these sanitary materials are thin and strong, and they are soft to the skin when they come in direct contact with the skin, as well as productivity and price. The top sheet of disposable diapers, which is one of the sanitary materials, is a material that is in direct contact with the skin. With a soft touch, there is an instant transmission of urine and less, so that it does not get wet back. . At present, fluffy fibers such as composite staple fibers are fused by hot air or partial hot pressing to join. However, although the non-woven fabric joined by hot air is fluffy and cushioning, in order to obtain sufficient cushioning, the non-woven fabric must have a high basis weight, and because its surface is composed of composite fibers, it is fused by hot air to fix the non-woven structure. Hard touch non-woven fabric. In addition, the point where the short fiber part is hot-pressed and fused has a low strength and a thin thickness, and the short fiber end irritates the skin. The non-woven fabric of the spunbond method is fused by hot pressing of the wire mesh. If necessary, it is -4-(2) 200406178. It is manufactured by hydrophilizing treatment. It has high productivity and strength due to the shape and arrangement of the fibers, which is shorter than that of ordinary planes. The properties such as water resistance and wettability are still not perfect. The spunbond nonwoven method is known as Fang Hei 6-304203, which is an open-cell catheter that is formed in contact with a liquid-absorbent core to form a recess through the top sheet), a core-sheath composite fiber, etc. Component fiber web is processed into embossed Kaiping No. 11-286863 by hot embossing), and two-component fiber webs such as core-sheath composite fibers are formed into a film by hot embossing (Japanese Patent Application Laid-Open No. 1 1-3 4 7 0 6 The method of No. 2 and the like, due to opening, shaping, etc., caused the non-woven invention of the present invention, the special invention of the 63rd Zai, which is composed of the fiber from 0.5 to 5 denier and the non-bonding unevenness. Deformed non-woven fabrics. However, the fibers of the fitting part are bent to form irregularities, and the technology of softening the fibers is not disclosed as necessary for sanitary materials. Another item of sanitary materials, three-dimensional pleats, back sheets, etc. are used Laminated with waterproof non-woven fabric, the former has strength, while the latter has micro-covering, waterproof fabric. The laminated non-woven fabric is still lower in function than the conventional single-layer wire mesh. The fiber has strength, which is more compatible with the adhesion of the meltblown fiber web. It is soft and soft. However, the non-woven fabrics and liquid-permeability improve the surface sheet method such as square top sheet and bottom sheet (Japanese patent kaikai or side-by-side composite fiber forming retention method (special fiber or side-by-side composite unevenness, The apex of the convex part is reported) etc. However, this material lacks flexibility. 1 The net structure described in Gazette No. 7944 has some knots, and the invention is a non-knotted untwisting to make it fluffy and liquid-permeable. Especially for leak-proof cuffs, screens and melt-blown fibers, the lamination of the two properties is not because of its excellent coverage. The basis weight net is as paper-like and feels as hard as paper, especially -5- (3) (3 200406178 At low basis weight, it tends to become brittle non-woven fabrics. The improvement method of fluffy degree is known. The upper sheet and the lower sheet are laminated in contact with the liquid-absorbent core, and the upper sheet forms the opening of the recess. A method for perforating a catheter (Japanese Unexamined Patent Publication No. 6-3 04 2 03), a method for forming and retaining a two-component fiber non-woven fabric such as a core-sheath composite fiber or a side-by-side composite fiber by hot rolling to form irregularities (Japanese Unexamined Patent Application, First Publication No. Hirakai) 1 1 -2 8 6 8 63), core-sheath composite fiber or side-by-side composite fiber Two-component non-woven fabrics are processed by hot embossing to form concavities and convexities, and filming the apex of the convex portion (Japanese Patent Application Laid-Open No. 1 1 -3 4 70 62), etc. Non-fabric lacks flexibility. Patent application publication bulletin (Japanese Patent Publication No. 63_i 7944) related to the present inventor's application discloses that the fineness of 0.5 to 5 denier is composed of a wire mesh, with some joints and non-woven fabrics. Non-woven fabrics with deformable concavo-convex deformation. However, the above-mentioned patent publication does not mention the use of meltblown fiber webs, and the improvement effect of the adhesion of the meltblown fiber webs disclosed in the present invention has not been disclosed. The purpose is to provide a fluffy material with a soft touch, high water permeability, low rewetting strength, and a useful sanitary material for the manufacture of disposable diapers, and to improve the spunbond non-woven fabric. The object of the present invention is also to provide an improved spunbond non-woven sanitary material which can be manufactured by a spunbond method with high productivity. The basic structure of the non-woven fabric of the present invention is a non-woven fabric composed of a thermoplastic synthetic fiber continuous wire mesh as a main body, which is integrally penetrated through the front and back surfaces of the non-woven fabric.-6-(4) (4) 200406178 The embossed or convex pattern formed by the high density domains of non-bonded fibers on both sides of the pattern and the non-woven fabric structure fixes the structure of the non-woven fabric. The spunbond non-woven fabric is characterized by a fluff ratio of more than 100% as indicated by the non-woven thickness ratio of the pattern surface. The use of a non-woven structure in which a melt-blown fiber layer is added to the thermoplastic synthetic fiber silk layer is also one of the preferred basic forms of the spunbond nonwoven fabric of the present invention. That is, a non-woven fabric formed by forming at least one layer of thermoplastic synthetic fiber continuous mesh and at least one layer of melt-blown fiber web, and hot-fusing the fibrous domain pattern through a portion of the front and back of the non-woven fabric, and The embossed concave or convex pattern formed by the high-density domains of non-bonded fibers on both sides of the non-woven fabric structure fixes the non-woven fabric structure, and the low-density domain of the non-bonded fibers of the non-woven fabric structure. The spunbond non-woven fabric with a bulkiness ratio of more than 100% as indicated by the thickness of the non-woven fabric on the surface can further improve the basic functions such as bulkiness and softness desired by sanitary materials. The basic structure of the spunbond nonwoven fabric (1) of the present invention is as shown in FIG. As shown in Figure 1 (I) and (m), the non-woven structure is based on (a) part of the embossed pattern of the heat-pressed fused fiber domain (hereinafter or referred to as part of the heat-fused part) and (B) the degree of unbonded fibers The embossed convex or concave pattern formed by the dense area is solid. The patterns (A) and (B) in Figure 1 are schematic patterns. The actual pattern can be different in shape and pitch from (A) and (b). In addition, each of the patterns (A) and (B) is arranged continuously or discontinuously independently of the front and back surfaces of the non-woven structure. The non-woven structure further includes a low-density domain of (C) 'unbonded fibers in contact with the above (A) and / or (B). Here, (A) part of the hot-pressed (5) (5) 200,406,178 embossed pattern in the fused fiber domain is formed by hot embossing, and (B) embossed convex or concave pattern in the high-density domain of unbonded fibers, It is a embossed pattern formed at a low temperature or at a temperature where the fibers are not fused. The non-woven fabric has a reverse-shaped pattern on the front side (first side) and the reverse side (second side) (see Figure 1 (m), 2 to 4). Fig. 7 shows a specific example of the spunbond nonwoven fabric of the present invention. In Fig. 7 (I), a non-woven structure forming embossed patterns of (A), (B), and (C) can be observed. Fig. 8 (I) is an example of the spunbond non-woven fabric of the present invention containing a laminate of meltblown fiber webs. As in the example of Fig. 7, it can be observed that (A), (B), and (C) patterns are formed. Non-woven construction. From Figures 7 and 8 above, it should be clear to understand the specific aspects of the non-woven fixed structure of the present invention containing (A), (B) and (C). The fluffing rate of the spunbond non-woven fabric of the present invention is the thickness of the non-woven fabric occupied by the low-density domain of the non-bonded fibers of the non-woven structure (a) to the non-woven thickness of the non-woven fabric with the convex embossed pattern surface (b) The ratio, that is, the 値 table calculated by the following formula (refer to FIG. 1 (IΠ)). Fluffing rate (%) = (b / a) X 1 0 0 Here, the thickness of the non-bonded fiber low-density domain (a) is the thickness before embossing at low temperature, so the fluffing rate can also use the thickness before and after embossing. The difference is calculated. Fluffing rate is an important factor that determines the softness of non-woven fabrics, and shows that the unevenness processing at low temperatures plays a role in kneading the non-woven fabrics. The spunbond non-woven fabric of the present invention can make the hydrophilizing agent mainly contained in the non-woven fiber high-density domain (B), so that the non-woven fabric can be modified to meet the needs of sanitary materials. Wet four characteristics. The present invention is described in detail below. -8-(6) (6) 200406178 The fibers of the spunbond non-woven fabrics of the present invention, polyolefin fibers such as polyethylene, polypropylene, or copolymers thereof, have low water absorption and high moisture absorption properties. Good and better. Polyester fibers such as polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate (PTT), or their copolymers are more suitable for strength and dryness. Preferably, polyamide fibers such as nylon 6, 66, 610, 12 or copolymers thereof can be made into a wet, soft non-woven fabric, and more preferably. If necessary, these composite fibers, mixed fibers or fibers mixed with other special functions can also be used. Non-woven fabrics must have sufficient strength to correspond to the body movement when wet on the surface, and due to productivity, the continuous filaments (filaments) are made into a net and spunbonded non-woven fabrics are formed by joining them. Spunbond non-woven fabrics have long fibers, practical strength, and excellent air permeability. They are different from wet or dry methods. They can be directly flaked without oil treatment, etc., and can use the unique water-repellent properties of fibers. nature. In order to make the non-woven fabric have strength, softness, and the feel of the fiber, the joining of the fibrous web in the non-woven structure is preferably performed by partial hot pressing and fusion. The area ratio of the hot-pressed fusion during partial hot-pressed fusion is preferably 5 to 40%, more preferably 5 to 25%, based on strength retention and flexibility. In addition to the ultrasonic fusion machine, part of the hot-press fusion can be used to heat the fiber web between the hot embossing rollers below the melting point of the constituent fibers. By this, the front and back of the non-woven structure are integrated, and the non-woven fabric is fully integrated. Spreads uneven patterns such as pinpoints and rectangles. Of course, the hot-pressed fusion portion is formed into a film by pressing, and the surrounding fibers have a touch specific to the fibers used. Non-woven fabrics that are only fused by this part are hot-pressed and fused. The thickness varies with the structure and configuration of the fiber. The thickness is not too large. The usual nets made by spunbonding, in which the fibers are arranged in a plane, are not bulky. Partial hot-press fusion is performed by applying heat and pressure to form a partial bond, and applying pressure to the embossed pattern at a temperature below the melting point of the constituent fibers. The remaining fiber shape that is different from those of the film melted above the melting point is bonded to form a "film-like" portion, which is different from the high-density portion formed by non-bonding uneven processing by hot-press fusion. As mentioned above, the spunbond non-woven fabric of the present invention is a non-woven fabric that is integrated with the front and back sides of a portion of the heat-pressed fusion portion to form a recessed portion having a high-density domain of non-bonded fibers on one side and a reverse side. Non-woven structure with convex parts of high-density domains of non-bonded fibers. Non-woven fabrics are integrally bonded to the front and back sides by hot-pressed fusion parts distributed in a dot-like manner. Other parts are convex or concave of high-density domains of non-bonded fibers. The embossed pattern and the low-density domain of unbonded fibers are formed by two domains with different fiber densities. Each is subjected to the kneading effect of low-temperature embossing forming. The fiber itself forms a structure that is easy to move, so it is soft and loose. Non-woven construction. The high-density domain of unbonded fibers is the area shown by B in Figs. I to 3, which is the area where the fibers are not fused or bonded. It is compressed by the uneven portions of the embossing roller for uneven processing, and the fibers are compressed and dense. The high-density fiber region 'is, for example, in a range of 15 to 35% in terms of fiber volume fraction. In the present invention, the area ratio of the high-density domain of the 'unbound fiber' is 5 to 50%, more preferably 5 to 25%. Here, the calculation of a part of the heat-pressed fusion portion is calculated from the shape of the embossed pattern after the heat-pressed fusion. The non-woven fabric of the sample was enlarged under a microscope, and the size and pitch of the film-like portions fused to each other were measured from -10- (8) (8) 200406178, and the area was calculated to calculate the area ratio of the entire area of the sample. The low-density domain of unbonded fibers is the area shown in Figure 1c. The fibers are not fused or bonded, which is equivalent to the compressed portion of the embossing roller without embossing. The fibers are not dense, and are generally regions having a fiber aggregation density before the uneven processing. Therefore, the low-density fiber is fluffy, has freedom of movement, and has the soft touch of the original fiber. For example, the volume fraction of the low-density domain fibers of the 'unbound fiber' is in the range of 5 to 15%. The area of the high-density domain of the unbonded fiber is to find out the trajectory of the deformation of the constituent fibers in the high-density domain of the embossed fiber, and determine the area ratio to the entire area of the sample. The shape of the fibers in the high-density domain of unbound fibers is only limited to the visible collapse of the constituent fibers, or also contains fibers with little deformation. The thickness of the high-density domain of unbound fiber is thin and the fibers are dense. Those who have been treated with the hydrophilizing agent mostly exist in the high-density domain, have good liquid permeability, smooth outer surface, and have a smooth and soft touch. The non-binding low-density domain is thicker than the high-density domain, the fiber density is low, soft and fluffy, and the liquid permeability is good, it has a barrier effect on the rewetting of the liquid, and the wettability of the liquid (Wet Back) is good. The above-mentioned effect will be explained by the sectional views of FIGS. 1 to 3. Figures 1 to 3 are diagrams useful for understanding the structural features of the non-woven fabric of the present invention. (A) A part of the hot-pressed fusion portion is a region for maintaining the strength of the entire non-woven fabric, and has an appropriate area ratio. (B) The non-bonding high-density domain B area 'has a shape that protrudes from the surface of the nonwoven -11-(9) (9) 200406178, making the entire nonwoven fabric fluffy. In addition, by making the B region contain more hydrophilizing agent ', the hydrophilicity of the portion can be greatly improved, and the liquid permeability through the B region can be improved. (C) The non-binding low-density domain C is a region of C, which has a high degree of fiber freedom and is rich in softness, and can give a soft touch. In addition, since the fluffy region c has a barrier effect on the liquid from the absorbent body, it has the effect of improving the wettability. The @ β boundary has the effect of making it easy to bend. In this way, the features of the present invention, that is, each of the regions' (A), (B), and (C) have the above-mentioned functions, and the whole has a function suitable for sanitary materials. The non-woven fabric of the present invention uses conventional composite fibers, which is completely different from non-woven fabrics which are fused and hardened by splicing or hot air treatment. In the present invention, because a fiber layer with a degree of freedom is imparted with a non-bonding concave-convex deformation, it can be made into a partially deformed (extended) fiber layer, so it has good cushioning properties and is not easy to compress when a load is applied. Therefore, it can be described as a product that is still fluffy under load, porous, and easy to permeate liquid (quick permeation speed). Once permeated, the absorbent liquid is not easy to get wet. The concave-convex deformation of the non-woven fabric of the present invention is a concave or convex deformation of any shape that is partially inconsistent with the pattern of the part of the bonded part. The shape, size, and depth of the concave and convex parts are related to the bonded pattern, which is important for the softness effect. Sex. The shape of the concave and convex parts can be, for example, straight lines, curves, squares, circles, pear skins, other continuous connected configurations, or discontinuous ones. Based on the soft effect, the coating degree of the concave and convex parts is 0 to 2 The greater the deep effect. In addition, the size of the pressing surface of the discontinuous convex portion is preferably from 0.1 to 5 mm, and the distance between the concave and convex portions is preferably from 0.5 to 5 mm. -12- (10) (10) 200406178 Fig. 1 is a schematic plan view of the entire structure of the nonwoven fabric of the present invention. Figures 2 and 3 show examples of square embossing on non-woven fabrics. Figures 2 and 3 show two examples of non-bonded concavo-convex processing patterns, and the figure of the heat-sealed portion and its distribution are omitted in the figure. For example, as shown in Fig. 3, the embossed ridges of the convex portions are rolled out to form the concave portions of the high-density discontinuous distribution. In addition, as shown in FIG. 2, the continuous embossing of the raised portions is continuous, that is, in a state where the high-density region is continuous, the non-embedded portions protrude from the fiber layer. The deformation pitch of a continuous pattern depends on its pattern, and is preferably 1 to 5 mm. The size of the concave portion is preferably 0. 0 to 2 to 3 mm wide, linear or dotted. Due to the high-density domain, the thickness is increased under the fluffy effect, the fluffiness of the non-woven structure is improved, and the thickness changes under load are small. The present inventors have found that when a hydrophilic agent is imparted to a non-woven fabric, the concentration of the hydrophilic agent in a high-density domain of non-bonded fibers is high. The larger the apparent thickness of the non-woven fabric, the softer it is. The distance between the concave and convex deformations and the size of the recesses are obtained. Unless the thickness is extremely large, a very fine fiber touch can be obtained. The fluffing rate of the non-woven fabric of the present invention is more than 100%, preferably 105 to 400%, more preferably 110 to 300%, and particularly preferably 120 to 200%. The larger the fluffing rate, the less the thickness decreases under load, and the non-woven cushioning is improved. Figures 5 and 6 illustrate changes in the thickness of the spunbond nonwoven fabric according to the present invention as a function of load. The spunbond non-woven fabric of the present invention has a large thickness and fluff under each load, and can be said to have good compression characteristics under load. Therefore, when the spunbond nonwoven fabric of the present invention is used as a topsheet of a disposable diaper, for example, the diaper has a continuous effect of being highly soft and fluffy when it is used over time and has a reduced thickness. -13- (11) (11) 200406178 In the wet state, there is also a small decrease in thickness. The return of the liquid from the absorbent body is large due to the high degree of bulkiness, and good results can be obtained. The method of imparting the embossed pattern of the spunbond non-woven fabric or the embossed pattern of non-bonded fibers is generally, for example, the surface has a concave, convex or concave-convex pattern, and the two sides are just fit between the rollers, and one of the surfaces has a concave and convex pattern. The rolls between the rollers and the flexible rollers, or processing between the plates, and special methods include the forced feeding of the cloth into the narrow gap between the rollers to form small wrinkles. In the fourth figure, an example of a concave-convex deformation is formed by having a circular concave-convex pattern on each surface, and the two just fit between the two rollers. The conditions for the formation of unevenness, especially the temperature and the pressure applied to the nonwoven fabric during processing. The processing temperature may be normal temperature, but if necessary, it may be heated and plasticized for easy forming. For morphological stability, the temperature is raised to a range where the fibers do not bind or harden for processing. For example, a polypropylene non-woven fabric is preferably in the range of 30 to 110 ° C. The embossing pressure varies depending on the temperature, but of course it must be set to a pressure sufficient for forming. Since the fiber cross section of the compressed part of the forming is deformed and softened due to the deformation effect of the part, it is also useful to use higher pressure treatment. Of course, the conditions used must not cause the fibers in the compression section to be temporarily fixed or heat-fused. For example, a polypropylene non-woven fabric is preferably in the range of 20 to 150 kg / cm. The spunbonded non-woven fabric of the present invention is preferably formed with high-density domain recesses of non-bonded fibers on one side of the non-woven fabric, and preferably has convex portions with non-bonded fibers formed on the reverse side. For example, when a high-density domain of continuous recessed portions is formed on one side, a high-density domain convex portion is formed on the other side, and the convexity is better than that of other regions. This is important to make the overall thickness of the non-woven fabric more than the thickness of the mesh, and to make the pro-hydration agent present in a specific location. The hydrophilizing agent treatment of the spunbond non-woven fabric of the present invention can generally use a dilute hydrophilizing agent solution, and adopt known methods such as dipping method, spraying method, coating method (roller coating machine, gravure coating machine, die opening, etc.). After the non-woven fabric is provided with a hydrophilizing agent, it can be dried by hot air, hot rolls, or the like. In the hydrophilization treatment, the high density previously imparted should be different from the adhesion distribution of the other parts of the treatment agent. When the treatment liquid is applied, the liquid is mostly contained in the low-density fiber, so-called rough parts. As the non-woven fabric is dried, the liquid moves to the easy-dry part. Therefore, the high-density domain of unbound fiber should be thinner with the non-woven fabric, and the ratio of the treatment agent will increase, and it will be easy for liquid to penetrate. In addition, once the liquid passing through is fluffed because the low-density region is not easily compressed, it leaves the absorbent layer and is not easily wetted. In this way, the hydrophilizing agent is mainly contained in the high-density domain of the unbound fiber, and can improve the liquid permeability, ideal wettability, and improvement of liquid flow and the like of the spunbond nonwoven fabric of the present invention. Before the hydrophilization treatment, corona treatment, plasma treatment, etc. should be applied to improve the degree of hydrophilization. Corona treatment and other treatments can be pre-printing treatments and other general treatments for improving wetting characteristics. For example, high-frequency oscillators are generated. High-frequency power is fed between the discharge electrode and the treatment roller to discharge. , The non-woven fabric is processed through it. Although it varies depending on the necessary wettability and processing conditions, the surface tension of the processing surface is preferably set to 37 to 40 millinewtons / meter and the discharge conditions are preferably set. However, when corona discharge treatment is applied, the wettability of the non-woven fabric itself is different. Of course, it is necessary to adjust the amount of the hydrophilizing agent to obtain the necessary performance. If the surface tension of the nonwoven is in the range of 37 to 40 millinewtons / meter, the affinity of the hydrophilizing agent and the non-woven surface fibers will be significantly improved. The hydrophilizing agent can have a concentration of -15- (13) (13) 200406178 and uniformly impart. . In the present invention, the hydrophilizing agent is preferably provided after the unevenness processing of the non-bonded fiber domain, but there is no particular problem before the unevenness processing. When used, the spunbond non-woven sanitary material of the present invention treated with a hydrophilizing agent, when used, should be based on the required level of characteristics of the hygienic material, and the properties and methods used should be selected instead of the difference in touch between the front and back of the fabric Related. open < Although the fiber local density domains of the uneven pattern are not joined to each other, but because they are stronger than the rest, when used as a top sheet of a diaper, they are arranged on the absorbent side of the non-woven surface that does not directly contact the skin, and When attaching importance to hydrophilicity, the skin contact surface with the high-density domain as the top sheet is in a better state. The bonded non-woven fabric of the present invention is used in a state where two or more layers of a non-woven fabric are laminated with at least one screen 'and a melt-blown net having at least one layer. In this case, the fiber used for the non-woven fabric may be the above-mentioned fiber raw material. If necessary, these composite fibers, mixed fibers, and mixtures with fibers having other functions can also be used. The screens can also have different raw materials at each layer, and the screens and meltblown fiber webs can also have different raw materials. Water-repellent and water-repellent raw materials, such as polyester fibers and polyamide fibers, must be treated or added with sand-based, fluorine-based, or wax-based water-repellent or water-repellent agents if necessary. . The non-woven fabric must have the strength corresponding to the movement of the body during use and be productive. 'The non-woven fabric formed by continuously joining at least one layer of a wire mesh and at least one layer of melt-blown fiber web' to form a non-woven fabric is good. The laminated structure can only be the lamination of the screen and the meltblown fiber web, but in order to compensate for the poor surface strength of the meltblown fiber web shown in Table-16- (14) 200406178, it is usually used in the lamination of the mesh layer. , You can also use the majority of each layer. Can also be a combination of layers. The spunbond non-woven silk is 0 · 5 to 5 dtex. It has practical strength and excellent air permeability. It can be directly pelletized with wet method or dry method without oil treatment. Take advantage of fiber water repellency and other properties. The melt-blown fiber web, as described in, for example, JP 5 6 -3 3 5 1 No. 2 3,9 7 8,1 8 5, USP 3,82 5,3 8 0, etc., forms the fine fibers of rice, covering Excellent performance, for example, polypropylene raw materials are more waterproof. Meltblown fiber webs are easy to join due to their fine fibers. On the other hand, when used alone, the joint strength feels as hard as paper. Therefore, the lamination of the silk screen and the melt-blown fiber web has the disadvantages of practical strength, coverage, water repellency, and water resistance. The bonding and fixing of the web is used to make the non-woven fabric have strength and soft touch. The area ratio of the hot-pressed fusion of the hot-rolled roll after partial hot-pressed fusion is preferably 5 to 40%, and more preferably 5 to 25% in order to maintain the strength. Partial hot-press fusion method, or passing the net between heated embossing rolls, thereby normalizing and spreading uneven patterns such as pinpoint, oval, and diamond shapes on the non-woven fabric. Of course, the hot-pressing fusion part is a fiber that is formed into a film-like circumference, and the characteristics that are especially used for wire mesh are retained. The joining conditions of the wire mesh layer are very thin due to the melt-blown fiber web layer, and they are joined by the melt-blown web. After the fiber is long, the method is unique to different Victoria. The newspaper, USP 1 to 6 is slightly water-repellent, low, and is still worse than silk, which makes up for their excellent product properties, and fiber is better. For softness, you can use the supersonic sound on the opposite side to form a stone shape and a rectangular shape, while its surroundings are tactile. Fiber formation -17- (15) (15) 200406178 The characteristics such as time, paper-like touch due to heat, the whole non-woven fabric is as hard as paper. This part of the heat-pressed fusion non-woven fabric varies in thickness depending on the fiber structure, embossed shape, and configuration, but it produces the unique bonding effect of the melt-blown fiber web layer, which becomes thinner and not fluffy. The improvement method of the fluffy degree, as shown in the prior art, has a method of opening, shaping and fixing, but it is not the second one formed by laminating at least one layer of wire mesh and at least one layer of melt-blown fiber web according to the present invention. Laminates with more than one layer, non-woven fabrics that integrate front and back by non-continuous parts of the surface that are hot-pressed and fused on the surface, are deformed to form fluffy or soft by non-combined unevenness, and there is no adhesion of melt-blown fiber web layer The effect is improved. Laminated meltblown fiber web is designed in a non-woven structure. The gist of the present invention is to laminate at least one layer of wire mesh and at least one layer of meltblown fiber web to more than two layers of laminates, which are dispersed on discontinuous parts of the surface. Non-woven fabrics with integrated front and back sides of the hot-pressed fusion section are treated with embossing to cause uncombined uneven deformation. The fiber parts of the hot-pressed fusion section distributed in points are integrated and the front and back are integrated, and other parts are integrated. The fibers of the non-bonding uneven portion still retain the soft touch of the fiber itself. Regardless of the bonding effect, the melt-blown fiber web layer is different from the hot-pressed fusion portion ′ and can be regarded as a fastened state, which is completely different from those that are fused and hard and non-slip through the heat treatment used to join the composite fibers. In addition, a non-combined concave-convex deforming force is imparted to the fibers with a degree of freedom, and a partial deformation (elongation) is applied to form a fiber layer, and a sufficient bulkiness can be obtained. This is different from the fibril layer when a load is applied, and it is difficult to compress. That is, curls that are easily bent are obtained, and softness and bulkiness (thickness) can be obtained. Fig. 6 shows the variation curve of the thickness of the non-woven fabric against the load in Example 8 and Comparative Example 8. -18- (16) (16) 200406178. The present invention can be described as a non-woven fabric which has the characteristics that it is not easy to deform under the load and has a small decrease in fluff under the load. In the spunbond non-woven fabric of the present invention, the embossed embossing pattern of the high-density fiber domain composed of non-bonded fibers, part of the bonded part pattern, and part of non-combined concave or convex deformation with inconsistent arbitrary shapes, concave Or the relationship between the shape, size, depth of the convex part and the combination pattern is important for the soft effect. For example, the shape can be straight, curved, square, round, pear skin, other continuous or discontinuous, but for the soft effect, the depth of the concave or convex part is preferably 0.2 to 5 mm, and the deeper the unevenness The greater the effect. The size of the pressing surface of the discontinuous pattern is from 0 · 1 to 5 mm, and the distance between the concave or convex portions is preferably from 0 · 5 to 5 mm. The patterns in Figure 1 (I) and Figure 3 are formed by embossing the embossed ridges of the convex portions and forming discontinuous discrete concave portions in a high density region. Moreover, in Figures 2 and 4, the continuous embossing of the embossment causes the recessed portions in the high-density region to become continuous, and the fiber layer of the non-embossed portion to be raised. The continuous embossing deformation distance is preferably 1 to 5 mm, and the size of the concave portion is 0.02 to 3 mm wide, which is preferably a line or a dotted line. The spunbond non-woven fabrics provided with these die-rolled embossed patterns are partially hot-melt fused with a pattern inconsistent with the die-rolled embossed pattern, and are arranged in the high-density domain of non-bonded fibers and the non-bonded fibers. Low density domain (refer to C in Figures 1 to 4). The area ratio of the concavo-convex embossed portion of the high-density region of the non-bonded fiber is preferably 5 to 40%, and more preferably 5 to 25% for good softness and fiber feel. When examining the practical side of the skin, of course, the larger the apparent thickness is, the softer it becomes. However, if the distance between deformations and the size of the recesses are not too large, a dense effect can be obtained, giving non-combination -19- (17) (17) 200406178 fluff before and after sexual deformation. The rate is preferably above 100%, more preferably above 105%, and particularly preferably above 130%. The method for imparting a concave or convex pattern is generally a spunbond non-woven fabric that is hot-melted and hot-melted at the working part, for example, between the rollers that have a concave, convex or concave-convex pattern on the surface, and one of them is just fitted. The surface has concave and convex rollers and is pressed between flexible rollers such as paper rollers, rubber rollers, resin rollers, or processed between boards. There are also special methods, in which the cloth is over-fed by a certain ratio between the rollers in a narrow gap to form a small wrinkle. The conditions for the formation of depressions and protrusions must be paid particular attention to the temperature during processing and the pressure applied to the cloth. In particular, the non-woven state of the melt-blown fiber layer of the present invention is easier to obtain a deformation effect than a non-woven fabric containing only a screen. Therefore, because of the softness, the adhesion effect of the melt-blown fiber layer is suppressed. It is better to set the processing temperature slightly lower than that of the screen element, and it can be appropriately set according to the fiber raw material. For example, when polypropylene is used as the raw material, it is better to set the temperature below 60 ° C, more preferably below 50 ° C, and if necessary, it can also be actively cooled. On the other hand, it can also be heated to a range where the fibers do not bond and harden, making it easy to be plasticized and processed to obtain stability in form. The pressure during processing varies with temperature, and can be set to a pressure at which deformation can be fully performed. The cross section of the fiber compressed by applying this deformation is more flexible and can be treated with higher pressure. Of course, it must be noted that the fibers in the compression part cannot be temporarily fixed and heat-fused. In a preferred aspect of the present invention, the high-density area of the convex portion extruded on one side is formed with a high-density concave portion on the reverse side. That is, for example, when a continuous recessed portion (high-density domain) is formed on one side, the high density on the other side becomes a convex portion, which is more prominent than other areas of • 20 · (18) (18) 200406178, which is a better aspect. It is of great significance to make the overall density of the non-woven fabric above the mesh thickness. Due to the formation of such high-density and low-density domains, the entire cloth becomes thicker, and it is easier to bend and softer, and it has a completely different touch from a thin, flat paper-like person. To further enhance the processing effect, multiple stages of processing can also be performed. The non-woven fabric of the present invention can be used with various treatment agents such as an antistatic agent, a softening agent, a hydrophilizing agent, and a slip agent, if necessary. When the spunbond non-woven fabric of the present invention is used in sanitary materials, the properties to be imparted and the methods used are selected according to the required level of characteristics of the sanitary materials. The difference in touch between the front and back of the nonwoven must also be considered. That is, although the extruded high-density domain is not joined, it is harder than other parts. For example, it is better to arrange the surface on the side that does not directly contact the skin, and consider the use of convex parts. The embossing process at low and medium temperatures of the present invention can be performed on the internal line of the spunbond non-woven fabric process, which is more economical, but it can also be introduced into a part of the diaper production and processing line for off-line processing. [Embodiments] Examples The following examples and comparative examples further illustrate the present invention. First, the measurement method and evaluation method will be described. (1) Basis weight of non-woven fabrics Several pieces of non-woven fabrics with a size of 10 cm square are taken, and the weight is expressed as the weight per square meter. -21-(19) (19) 200406178 (2) The thickness of non-woven fabrics is made by Zhongshan Electric Industry Co., Ltd., a compression elastic testing machine EZ, to measure an area of 4 square centimeters at 1.3, 10, 37.5, 50, 1〇 Measured under each load of 0 g / cm. (3) Fluffing rate of non-woven fabrics The change rate of the thickness of non-woven fabrics (under a load of 10 g / cm2) before and after the high-density domain imparted to non-bonded fibers according to the present invention is the fluffing rate. (4) Tensile test specimens with a width of 3 cm and a length of 20 centimeters when the strength of the non-woven fabric and the stress at 5% elongation are used. Tensilon made by Shimadzu Corporation is used for a tensile test at a grip width of 100 mm and a test speed of 300 m / min , Measure the longitudinal and transverse strength and stress at 5% elongation. (5) Bending softness of non-woven fabrics The softness index and the measuring method of bending softness are as follows. The measuring method is to press the full width of the test piece in the vertical direction with a ruler, leaving one end in the measurement direction of 1 cm, and the other end of the test piece is mounted on the end of the ruler in a circle without creasing. Press the end of the side with the ruler and hold down with your hand to slide the ruler in the circle on the test piece. Take the elongation point of the ring under the elasticity of the sample as the end point, and the length from this point to the end of the ring side is the critical length (mm), expressed as the average 値 on the front and back sides. The shorter the softer. (6) Measurement surface of water permeability The water permeability is a top sheet of non-woven fabric used as a disposable sanitary material, and the side used as the skin surface is a water permeability measurement surface. Table 1 "Top" and "Bottom" of the "Permeability measurement surface" column each show characteristics for the skin surface side -22- (20) (20) 200406178 (7) Instantaneous water permeability superimposed 10 sheets of toilet paper as An absorber, a measuring device (approximately 800 g, 10 cm square, with a hole of 25 mm in diameter at the center, and two electrodes connected to the timer toward the center) are placed on the absorber, and the measurement is performed on the absorber and the measuring device. A test cloth of 10 cm square (above) was placed between the test cloths, and one drop (0.1 cc / drop) of physiological saline solution was dropped from a 15 mm burette above the cloth. The time from dripping to the end of passing through the cloth was measured with an electrode, and the instantaneous rate of water penetration (seconds) was 〇 (8) 5 cc rate of water penetration (seconds / 5 cc), and the amount of rewetting (g) was the characteristics of the solid absorbent body. The specific filter paper ("9 3 9" made by Eaton Dikeman Co., Ltd., 10 cm square x 3 sheets stacked) was an absorber, and was placed under a measuring device (same as (6) Instant water permeability measuring device). Place a test cloth (10 squares square) on the absorbent body. First, 5 cc of artificial urine was dripped from 25 mm above it. The artificial urine-based physiological saline solution was adjusted to 45 ± j > dyne / cm (鼋 Newton / meter), and the dropping speed was 3.3 seconds / 2 5 cc. The time from dripping to the end of passing through the cloth was measured with the electrode, and it was 5 CC permeation rate (seconds / 5 cc). Secondly, the artificial urine is directly added to make the liquid content of the absorbent body constant, and the total liquid amount is about 4 times the weight of the absorbent body. In this state, a load of 800 g / 10 cm square was applied to the test cloth for 3 minutes to fix the distribution of the liquid in the absorbent body. Secondly, pre-weigh filter paper (

Take a test piece (20 cm square) and measure it according to JIS-L-1 092. [Examples 1 and 2] Titanium-containing polypropylene (M FR = 40 measured under the conditions of Table 1 of JIS-K 7210) was used as a raw material, and melted and extruded into a long fiber through a circular cross-section nozzle. The vicinity of the mouth is cooled from the side, and at the same time, it is taken up by a traction take-up device such as an aspirator. After the filament from the traction and winding device is opened by the electrostatic device, it is collected on a moving metal mesh conveyor belt to form a web. Pass the net through the embossing / flat rolls heated to 13.5 ° C, staggered with a circular shape of 0.43 mm in diameter and staggered at a pitch of 1.5 mm (area ratio of about 7%). The parts are hot-pressed and fused to obtain a non-woven fabric with a pinpoint spread pattern. The constituent fibers of the obtained spunbond non-woven fabrics were 2.8 dtex (Example 1) and 2.0 dtex (Example 2) round cross-section yarns, with a partial heat-fusing area ratio of 7%, and a basis weight of 20 g / m2 each . The non-woven fabric was passed through a continuous linear honeycomb pattern with a side width of 0.9 mm and a line width of 0.1 mm (the tortoise shell pattern: refer to FIG. 4) (rolling area ratio of 12.5%), and the pitch of the die patterns was longitudinally 2 · 8 Mm, width 3.2 mm, depth 0.7 mm) between the embossing roller (100 ° C) and the rubber roller with a surface hardness of 50 degrees (JIS-A hardness) at a line pressure of 100 kg / cm. There is a high density area extruded around the turtle shell, and a soft non-woven fabric in the center. In this non-woven fabric, a gravure method is used to give 0.45% by weight of a block copolymerized polyether of polyethylene glycol propylene glycol, and polyether modified polysiloxane is used as the main component to form an active agent of -25- (23) (23) 200406178. It is a hydrophilizing agent and a non-woven fabric for sanitary materials. The performance evaluation results of non-woven fabrics are shown in Tables 1 and 2. The low-density domain (grooved surface) of the non-bonded fiber on the front side of the non-woven fabric is configured as the skin surface side of the top sheet. The disposable diaper produced is a high-density inter-domain fiber layer bulge compared with the conventional non-woven structure. Soft, improved wettability, good dry and soft non-woven feel. Low decitex Example 2 is smoother and softer. (Example 3, Example 4) The non-combined embossing was changed to a discontinuously dispersed tortoise shell embossing opposite to Example 1 (0.45 mm on one side, embossing area ratio of 25%, embossing pitch Non-woven fabric of the present invention having a length of 2 · 8 mm, a width of 3 · 2 mm, and a depth of 0 · 6 mm) as in Example 1 yielded 2.8 dtex and a basis weight of 20 g / m 2. They are listed in Tables 1 and 2. With the non-woven fabric as the top sheet, the continuous convex surface (the front side of the non-woven fabric) in the low density domain was used as the top sheet skin surface in Example 3, and the high density of the non-woven back surface was used in Example 4. The discontinuous convex surface of the domain is the skin surface of the top sheet, and a disposable diaper is made. As in Example 1, the non-woven fabric is superior in softness and wettability as compared with the conventional non-woven fabric. In addition, the front and back surfaces of the non-woven fabric are inverted as a top. The filmmaker (Example 4) has spot-like bulges in the high-density domain, and the surface is slippery and has a dry touch. [Example 5] In order to form a non-bonding embossed discontinuously dispersed grid ridge (one side-26- ( 24) (24) 200 406 178 0.3 mm x 0.7 mm, with an area ratio of 22% and a depth of 0.6 mm). The rest of the roll-fitting combination of the grid-embossed grid grooves was the same as in Example 1, and a non-woven fabric of the present invention with 2.0 dtex and a basis weight of 18 g / m 2 was obtained. The surface of the non-woven low-density domain continuous convex part (non-fabric front surface) is the top sheet skin surface, and a disposable diaper is made. As in Example 1, compared with the conventional non-woven fabric, it has superior softness and good wet-back performance. Examples 6 and 7] Before applying a hydrophilizing agent, corona treatment was performed, and the conditions of the corona treatment were such that the discharge amount was 30 watts per minute per square meter under an ambient gas at a room temperature of 22 ° C (the discharge degree was 2.2 watts per square centimeter). As a result, the surface tension of the non-woven fabric was 37 mN / m. Considering the improvement of the wettability by corona treatment, the amount of the hydrophilic agent was changed to other than 0.3% by weight, as in Examples 1 and 3. Inventive non-woven fabrics are used in Examples 6 and 7. The disposable sanitary material using the obtained non-woven fabric as a top sheet is softer and has less adhesion of a hydrophilic agent than a conventional non-woven fabric composition. Excellent water permeability as in Example 1 and Example 3. It is a good product with a few softeners and a dry, soft, non-woven feel. [Comparative Examples 1, 2, 3, and 4] In Examples 1, 2, 5, and 7, non-binding bonding was not performed, and a hydrophilizing agent was imparted.

The sanitary materials of the present invention shown in Tables 1 and 2 (with non-woven fabrics, have good fluffy properties, the fluffy rate is more than 110%, the thickness change is small when a load is applied, the load is excellent in compressibility, and it is soft and has good water permeability. [Example 8 and Example 9] Polypropylene (MFR = 40 measured in accordance with the conditions in Table 1 of JIS-K7210), and the long fibers melted and extruded from the nozzle with a circular cross-sectional area were spun near the spinning mouth. The side is cooled, and at the same time, it is taken up by a drawing and winding device such as an aspirator. After the filament from the drawing and winding device is opened by an electrostatic device, it is collected on a moving metal mesh conveyor belt to form a wire mesh (2 · 8 Dtex (Example 8) and 1.2 Dtex (Example 9), each 6.5 g / m2. On this web, polypropylene (M FR measured according to the conditions in Table 1 of JIS-K7210 = 7 00) as a raw material, a high-temperature high-temperature hot-air laminated two-piece melt-blown fiber-type net (fiber diameter 1.8 micrometers' 1 g / m 2) is blown out from two slits beside the discharge nozzle. The screen made as above becomes a laminated screen (15 g / m2). The screen is passed through a embossed / flat roll heated to 130 ° C An oval pattern with a major diameter of about 0.9 mm 'and a minor diameter of about 0.5 mm and an area of 0.36 square millimeters is diagonally arranged at an angle of 30 ° in a diagonal direction of about 3 mm in length and a width of 1.7 mm in width. Area ratio of 15%) The pattern of the heated rolling booth, a part of the non-woven fabric with an elliptic dot-like scatter (twill) pattern was fused by hot pressing. -31-(29) (29) 200406178 The non-woven fabric Pass a roller (401) with a side line of 0.9 mm and a line width of 0.0; [mm of continuous linear honeycomb patterns (turtle shell grooves) (rolling area ratio of 12 · 5%, depth of 0.7 mm) and a surface hardness of 50 Degree (jIS-a hardness) of rubber_Kunma, embossed with a linear pressure of 100 kg / cm. A high density area extruded around the tortoise shell pattern, and a soft non-woven fabric bulging in the center. Properties of non-woven fabrics The evaluation results are shown in Tables 1 and 2. Non-woven fabrics with a screen fineness of 1.2 dtex (Example 9) have non-woven surface fibers that are smooth and have a softer touch. These non-woven fabrics are made of three-dimensional pleats. The disposable diapers are made of non-woven fabrics that have not been conventionally softened, and they are soft and have good thickness. This non-woven disposable diaper with a microporous PE film layer as a back sheet has a soft touch not available in conventional non-woven laminated non-woven fabrics, and can withstand sufficient practical strength and surface strength. Example 10, Example 1 1] In order to obtain non-combined concave and convex deformation, the embossing was changed to a discontinuously dispersed tortoise shell embossing opposite to Example 8 (0.45 mm on one side, 25% embossing area ratio, deep Except for 0.6 mm), the nonwoven fabric of the present invention was obtained in the same manner as in Example 8 with a basis weight of 15 g / m 2 (Example 10) and 17 g / m 2 (Example 11). The performance evaluation results of non-woven fabrics are shown in Tables 3 and 4. This nonwoven fabric is used as a three-dimensional pleating to produce a disposable diaper. As in Example 8, compared with the conventional non-fabric non-fabricated fabric which has not been softened, it has superior softness and good thickness. In addition, if the non-woven fabric is reversely laminated with a microporous PE film as the back sheet, the non-bonded fiber has a high-density domain dot-like bulge, which is a product with a smooth surface and a dry feel. • 32- (30) (30) 200 406 178 [Example 1 2] In order to obtain non-combined uneven deformation, discontinuous discrete lattice ridges (0.3 mm x 0.7 mm on one side, 20% rolling area ratio, 0.6 depth) Millimeters) of embossing, passing through a combination of rollers with a grid concave pattern that fits into the pattern, as in Example 8, a non-woven fabric of the present invention having a basis weight of 15 g / m 2 is obtained. The performance evaluation of non-woven fabrics is shown in Tables 3 and 4. This nonwoven fabric was laminated with a microporous PE film as a back sheet to make a disposable diaper. As in Example 8, compared with the conventional non-woven fabric, it had excellent softness and good thickness. [Implementation 1 3] In order to obtain non-combined concave and convex deformation, continuous embossed lines (line width 0.2 mm, interval 0.5 mm, embossed area ratio 29%, depth 0.6 mm) were formed. The surface hardness was 60 Degree (JIS-A hardness), 15 mm thick rubber roller combination room, the same as in Example 8, to obtain a non-woven fabric of the present invention with a basis weight of 17 g / m2. The performance evaluation results of non-woven fabrics are listed in Tables 3 and 4. The non-woven fabrics are curled diagonally. Compared with the non-woven fabrics before the softening treatment, the non-woven fabrics are superior in softness and thickness. [Example 1 4] The raw polymer polypropylene (MFR = 40 measured according to the conditions in Table 1 of IS-K 7 2 1 0) was changed to a random polypropylene copolymer (ρε 3%, MFR = 35 -33- (31) Except for the silk screen (1.8 dtex, 6.5 g / m 2) of (31) 200 406 178), as in Example 8, a non-woven fabric of the present invention having a basis weight of 15 g / m 2 was obtained. The performance evaluation results of non-woven fabrics are shown in Tables 3 and 4. The surface of this non-woven fabric has a polyethylene-like slippery feel. Compared with the non-woven fabric before the softening treatment, the non-woven fabric has better softness and a good thickness. [Example 1 5] In Example 8, the single-sided screen layer was made outside the net of 1.2 dtex (3.3 g / m2) and inside 2.8 dtex (3.3 g / m2). As in Example 8, a nonwoven fabric of the present invention having a basis weight of 15 g / m 2 was obtained. The obtained non-woven surface layer is a non-woven with a slippery feel and a thick feeling. [Example 1 6 and Example 1 7] Polyethylene terephthalate (viscosity 々SP / C = 0.75) and nylon 6 (relative viscosity T? Rel = 2.7) were used as the raw materials for the silk screen, meltblown Polyethylene terephthalate (viscosity 77 sp / 00.42) and nylon 6 (relative viscosity 7? Rel = 2.3) are used as the polymer for the fiber, and made into a silk screen (2.0 dtex, 8.3 g / m 2 ), Melt-blown fiber web (PET = 2.4 microns, 3.4 g / m2 for each fiber diameter, N6 = 1.6 microns, 3.4 g / m2), embossed through the woven eye (0.5 mm square, compression area ratio (15%) between the rolls / planar rolls, except polyethylene terephthalate screen at 2 05 t, nylon 6 screen at 1861, except for partial hot-press fusion, as in Example 8, the basis weights were 20 g / sq. Each. The present invention is non-woven. The performance evaluation results of non-woven fabrics are listed in Tables 3 and 4. 〇-34- (32) 200406178 These non-woven fabrics each have superior softness and better thickness than non-woven fabrics before softening treatment, especially in Example 16 This effect is even more pronounced with polyester nonwovens. These non-wovens are not only sanitary materials, but also used in packaging materials, printing materials, simple clothing, etc., which are unprecedentedly soft non-wovens.
