200426268 成纖維網之網形成纖維i,及藉由高壓水流壓力而可移動之 纖維空間擴大纖維Η,首次可確保充分之纖維空間,使棉 纖維4充分進入不織布2内,並且交織。 如此,棉纖維4所組成之棉纖維層3形成於不織布單面 側,獲得纖維片1。 由以上,作為纖維空間擴大纖維II,本發明採用藉由水 流而移動並偏在之纖維類型,及如同潛在捲縮性纖維一 般,藉由水流而移動,但回到原本位置,不大幅偏在之纖 維類型。若使用前者纖維類型,具有纖維片丨形成毛細管梯 度之優點。若使用後者纖維類型,具有纖維脫落少,而且 在纖維片發現伸縮性之優點。 其次,參考圖4’說明本發明其他實施型態。於此實施型 態,僅說明與先前所述實施型態之不同點,未特別說明之 點,適當適用先前所述實施型態相關之詳述說明。又,於 圖4,與圖1相同之構件標示相同符號。 如圖4所示,本實施型態之纖維片1〇係由複合片所構成, 其中該複合片係'棉纖維層13、13各_部分進人合成纖維所 組成之不織布12之各面。於纖維片10,由形成有各棉纖維 層13、13側朝向纖維片1G之厚度方向之中央,棉纖維4之量 逐漸減少。又,將纖維片i作為整體來看,由形成有各棉纖 維層13、13侧朝向纖維片10之厚度方向之中央纖維量變 夕。總言之’由形成有各棉纖維層13、13侧朝向纖維片⑺ 之厚度方向之中央,纖維間距離逐漸變小。其結果,由形 成有各棉纖維層13、1 3側朝向纖維片丨〇之厚度方向之中 92590.doc -15- 200426268 央,毛細管力逐漸變高。亦即毛細管力產生梯度。藉此, ㈣成有各棉纖維層13'13侧朝向薄片内部之液體牵引性 變高,即使纖維片1與液體接觸,纖維片1之表面呈現乾燥 的感覺。 本實施型態之纖維#】0 iI γ 月10由於兩面形成棉纖維層13,因此 任一側接觸肌膚均可。 本毛月不限於4述貫施型態。例如:於圖工所示實施型 態’於未形成有棉纖維層3侧之表面,不存在棉纖維,但於 未形成有棉纖維層3側之表面,亦可存在棉纖維。 【產業上之利用可能性】 本發明之纖維#防止以往棉片以產生之棉纖維眼孔堵 塞,因此呈現柔軟的手感。又,本發明之纖維片係由棉纖 維層側朝向薄片㈣,毛細管力具有梯度,因此液體之牵 引性高,因此即使纖維片與液體接觸,纖維片側之表面呈 現乾燥的感覺。並且,相較於同基量之棉纖維單獨形成之 棉片本發明之纖維片之棉纖維層係張力強度等較高,可 使棉纖維層低基量化。使棉纖維層低基量化有利於提高棉 纖維層之柔軟性。 【圖式簡單說明】 圖1係表示本發明之纖維片之一實施型態之縱剖面構造 之模式圖。 圖2係表示圖1所示之纖維片之製造工序圖。 圖3係表示使棉纖維之棉網交織於不織布之狀態之模式 圖0 92590 doc -16- 200426268 圖4係表示本發明之纖維片之其他實施型態之縱剖面構 造之模式圖 【圖式代表符號說明】 1、10 纖維片 2、12 不織布 2f 布捲 3 ^ 13 棉纖維層 3f 棉網 4 棉纖維 5 無端緣傳送帶 6 喷射嘴 I 網形成纖維 II 纖維空間擴大纖維 92590.doc -17
