1 ' I 五、發明説明(·!) 發明領域 本發明係有關一種織物熱結合方法。其運用係意欲用在 可用完即丟之吸收性物件。 發明背景. 用完即丟之吸收性物件,特別是用完即丟之紙尿布係早 已習知之大量製造物件,其主要係設計由嬰孩及大小便失 禁患者穿著。此尿布係穿著環繞著該穿用者之下體,及意 欲吸收及盛裝小便及其他身體排放物,如此防止可能接觸 此一使用中尿布之物件(例如衣服、床得、其他人等等)弄 髒、弄濕、或類似之污染。近年來,套穿式(pull-on)尿布 之用完即丟紙尿布業已出現在市場上,且具有固定侧邊之 用完即丟套穿式尿布係特別流行。典型地,該用完即丟套 穿式尿布之固定侧邊係藉著結合該前部侧衽至該後部侧衽 製成。為結合故,該侧衽之接觸表面需至少局部熔化。然 而,吾人想要的是避免對應該結合區之侧衽外表面熔化。 一般言之需要一項技術,以准許結合數層厚材料,而不會 導致在該外表面上形成堅硬、刺激之突起物。其已證明現 行技術更適於結合薄材料。因此,於該技藝中已知結合厚 材料之問題,但就本申請人所知,至今唯一提出解答係在 此所敘述者。 典型之先前技藝方法係該習知之熱結合方法,利用鋼 製、鋁製及銅製或其他材料製成之熱針銷,具有高導熱係 數,以傳送熔化所需之能量進入欲結合之織物。對於像薄 膜之薄材料,該熱針銷接觸及熔化該織物結構之外表面= -4- 本紙張尺度適用中國國家標準(CNS ) A4規格(2丨0'乂297公釐〉 I--.-------;衣-- (請先閔讀背面之注意事項再填寫本頁) 訂 A7 B7 經濟部中央標準局員工消費合作社印製 發明説明( 針:厚材料,其較佳為該熱針銷貫穿整個織物結構。該 =針销(上下動作導致具有㈣壁面之 =材料將位移及運送至該織物結構之表面,而在冷卻之 <形成堅硬、刺激之突起物。4確保發生―有效之社合, 可隨後壓縮該織物結構。賴如此,在該壓縮工具^放入 ,當位置之前’該熱針銷必須移走,導致—複雜之操作。 只有當該壓縮工具由該織物結構移去時才冷卻該材料。 於美國專利第4,667,552號中大致,但非全部地教導熱塑 ,材=之一薄膜材料之穿孔。由一旋轉之圓筒裝載著已加 煞疋穿孔針銷,及用諸如一可變形滾輪之壓力裝置迫使欲 牙孔薄膜抵住針銷·該熱針銷係由該塑膠薄膜之頂部進 入乂及在该針銷貫穿該薄膜之後,當該熱針銷熔化周圍之 薄膜時,琢薄膜係熔化成一混亂結構。在穿孔之後,由於 突起物之激增,該薄膜未有一平滑面及一設有一组織結構 疋正向面。該技術不適於結合厚材料。 美國專利第4,5 19,798號為一代表方法,其利用熱能軟化 二或更多層熱塑性材料’俾能結合。該專利揭露一用完即 丢之紙尿布結構’其中一吸收核心係裝入多數薄片間之鞘 囊内。每一薄片係由一諸如聚乙烯之材料製成,其將熱 封’而不須一黏接劑。該尿布係藉著加熱及密封彼此全然 重疊之聚乙烯薄片邊緣’且在該吸收核心之邊界外侧製 成。 於美國專利第4,919,738號中敘述自體生成之複數層疊層 或薄層薄片材料。更詳細言之,該專利教導一將複數薄層 5- 表紙張尺度適用中國國家標準(CNS ) A4規格(2I〇X297公釐 (請先閲讀背面之注意事項再填寫本頁) ann - —-^ϋ UK— · A7 Β7 3 五、發明説明( 動,地結合在—起之方法,最少一薄層包括熱塑性材料。 忒®層構造係經由使用壓力偏向之疊層滾輪完成,該等滾 輪之間係以一預定之表面速度差操作。事實上,於一些疊 層中’坪接位置部份可能突出而非凹陷,導敢堅硬、刺^ 之哭起物。 於美國專利第3,733,238號中藉著超音波震動設備將多層 熱塑性材料焊接在—起。多數隔開之超音波震動傳送構件 具2直接接觸該薄片似成分之工作表面,而用於配合位在 該薄2似成分相向侧面上之相向隔開鐵砧表面,以生產熱 塑性登層材料之全寬織物。如明顯易見者’該技術要求各 層熱塑性材料總是直接物理接觸該機械能傳送工&,如此 導致該織物之污染、機器磨損及因此機器無效率。 人於美國專利第4,61〇,681號中揭露―種六層結構组成之缝 合線’包括該外織布層、外覆薄片之内部不滲透層、及形 成該衣服内襯之可滲透層。為形成一小及不突出胃之接合 層’用多數缝線完成該超音波密封,而形成受壓區及浮凸 缝線區。該技術係如同上面之機械式本質,及導 之污染、機器磨損及機器無效率。 文以八 美國專利第4,9G9,8G4號中概述-結合厚層材料之裝置, 其揭露一用完即丟之訓練便溺習慣用褲予之縫合線衣而藉 著縫紉結合之。 〇 W0 96/193 13專利敘述一種形成穿透孔隙之方法,該孔 隙在一織物中為孔洞及/或裂缝之形式,意欲形成吸ί性 物件之—部份,例如一吸收性物件之頂部薄片係設有穿 本紙張尺^ —^----——;策— (請先鬩讀背面之注意事項再填寫本頁) 訂 經濟部中央標準局員工消費合作社印製 -6- A7 經濟部中央標準局員工消費合作社印製 五、發明説明(4 ) 孔,以獲得液體之滲透性。根據本發明,用來自一照射源 之至少一集中電磁波束或微粒束照射在—織物之至少一 ^ 面上,及照射在那些欲形成孔隙之織物區。於照射^間, 孩織物可能接觸另一織物,其包括類似於第一織物之同類 材料,及選擇該射束之性質及該照射時期之持續時間,: 致第一織物及/或另一織物中之材料將供以充足能量,俾 結合緊鄰該孔隙附近之織物。一流體可能運送至該織物上 之焦點附近,以便由該織物所形成之孔洞移去熔化/燃燒 /蒸發之材料。即使未接觸欲結合之織物,該技術係集中 於穿孔,及導致熔化材料位移及傳送至該頂部薄片表面。 針刺法係一機械式接合技術’用於結合織物材料。於美 國專利第5,397,632號中,用於一改良式汽車縱深之空氣濾 清器之非編織織物係在間隔位置機械式地固定。於該針刺 法操作期間’具有一纖維推進架構之多數缝針係穿過所有 織物。如此,各種織物變得經由主要纖維及細絲之糾結網 機械式地互連及互鎖。於此缝針插入及縮回期間,來自上 織物之主要纖維及來自中介織物之較易動纖維係向前鑽入 該下織物。最終產品之表面摸起來並不平滑。 上面先前技藝意圖之結果是,熟練該技藝者已認知想要 提供一種結合厚織物之方法,特別用於用完即丟之吸收性 物件,而消除該熔化織物材料之凝固在外表面上所造成之 堅硬、刺激突起物之出現;不需使用熱傳工具以物理接觸
