Description

583093 故、發明說明： 發明背景 發明範圍 本發明大致係關於薄膜/不蟠銘人 f ^ 、、、 叶肤4、、乘複合物，特別係關於一種點 燦接之1¾彈性膜/不織複合物，並 /、係在製作後，延展該複合 物，以將藉溶接點黏合該不織物而在不織物上所形成之無 彈性膜破裂，而使其成為可呼吸。 相關技藝 在消費性可拋棄物市場之尿布產物等等，需要改良立合 身性與舒適性。為滿足此需要所努力方向可包括改進疊芦 之可傳遞高延伸性、具高彈性回復性、高透氣性、以及其 耐撕性。 在過去，於不織疊層達到高伸展所用技術，多半會損及 該不織物纖維或結合劑，使疊層強度降低，尤其是張力強 度此夕卜，以既往技術製得之叠層，經常缺乏足夠彈性恢 復性’以在所需應用上有最佳表現。 這類疊層透氣性一般是在膜疊層不織物前，先在膜上開 孔。而膜對不織物疊層多半以使用黏劑為之。這類黏劑傾 向堵住疊層中的孔或缝，因此潛在地降低所需之透氣性。 透氣性亦可由其它開孔方法將膜開孔而產生，例如在膜 與不織物疊層後對膜穿孔。然而此種穿孔方法造成在整個 疊層上不同的弱點。這些弱點一般形成開始撕裂點。 既往技藝中，通常需進行許多煩累及昂貴步驟以產生具 有所需性質之疊層。 〃
O:\70\70184-920714.DOC 583093 因此有需要開發一種疊層及其製造方法，其具高彈性及 彈性恢復性’供於可掘棄物件市場使用。此外，亦需開發 一種登層及其製造方法，其可消除既往技藝疊層上形成之 初始撕裂點。另外需要製造一種疊層，其在疊層預定伸展 延長度上具有相當高抗撕裂性。最後，需要減少製造該疊 層必要步驟數目，而同時保持有上述性質。 發明摘要 本發明係提供一種改良之薄膜/不織複合物，其僅在橫機 械方向伸展’且具有流體與空氣可滲透性質。 本發明一項具體實例之薄膜/不織複合物，包含兩合併層 貼合在一蕊層。該合併層由單向性及非單向性纖維組成。 該單向性及非單向性纖維提供複合物上之可伸展及不可伸 展區域。 複合物各層以個別點熔接。一項具體實例中，以一種超 音波焊頭熔接該複合物。經熔接後，複合物上形成下列各 別區域：未溶接區，結合區，及膜區。該未溶接區係指環 繞溶接點之複合物區域。該溶接點為形成實際結合形式， 其係在熔接步驟由外力及熱/熔融能量作用之聚合物融 體。該膜區為非常薄之可渗透聚合物原料膜，於熱/溶融能 量施加後仍保持不變者。 形成複合物後，複合物部份區域具高彈性。該複合物可 由使用者伸展以在膜區撕開膜，使膜具有透氣性。該合併 層纖維在機械方向張力破裂對在橫機械方向張力破裂比例 為約1.8:1。
