M274925 ⑴ 八、新型說明 【新型所屬之技術領域】 本創作是有關一種薄型且軟質，可賦予和襯褲形成一 體感的內褲襯片，尤其在肌膚側表面不容易使液體擴散而 可發揮迅速將液體吸入功能的內褲襯片。 【先前技術】 內褲襯片是於女性除了生理日以外的日子裏黏著在襯 褲的股部部內側使用，使用於吸收月經等膣分泌物。該內 褲襯片是賦予和襯褲形成一體感的薄型且軟質，並且具有 保持膣分泌物等液體的能力，並期待液體不易擴散到肌膚 側表面物。 以下的日本創作專利文獻1記載的內褲襯片是以表面 材覆蓋吸收材的肌膚側表面的構造。上述吸收材爲織物單 位面積重量40g/m2左右的複合合纖纖維所形成的親水性 不織布。上述表面材是以棉纖維1 〇 〇 %，噴水投緯製法所 形成的不織布，使用較上述吸收材薄的材料。該內褲襯片 是將液體吸收保持在上述吸收材，上述表面材並非可以保 持液體的厚材，而是具有使液體穿透到吸收材的功能。因 此’在上述表面材形成將液體導向吸收材用的多數個透液 孔。 以下的日本創作專利文獻2記載的內褲襯片是將單一 的不織.布薄片定位在肌膚側，在穿著側具有不透液性隔 餍。上述不織布薄片是以卡式形成混合人造纖維和聚酯纖 -5- (2) M274925 維的纖維網，利用從噴嘴所噴射的水流使上述纖維經緯交 織。並且藉著上述水流的賦予使得不織布薄片表面的纖維 橫向移動而形成凹陷部。更將黏合劑溶液賦予上述不織布 薄片’黏者纖維間的同時，維持著上述凹陷部的形狀，並 可提高壓縮時的彈性恢復功能。 〔創作專利文獻1〕日本特開平8 - 2 4 2 8 9號公報 〔創作專利文獻2〕日本特開平7 - 1 3 8 8 6 5號公報 【新型內容】 〔新型所欲解決之課題〕 如上述創作專利文獻1所記載，以往的內褲襯片是以 表面材覆蓋吸收材的表面，使肌膚側表面的纖維密度密 緻，再賦予液體時不易造成對肌膚側表面的破裂等。並 且，表面材形成透液孔，將賦予表面材的液體從上述透液 孔引導到其下方的吸收材。 但是，吸收材以表面材覆蓋的構造上，不容易迅速地 將賦予表面材的膣分泌物等液體引導到吸收材，液體容易 滯留在表面材上。爲了將賦予表面材的液體迅速引導至吸 收材而提高形成在表面材上的上述透液孔的開口面積率 時，吸收保持在吸收材的液體會因爲體壓而容易滲出表面 材的表面。 並且，上述創作專利文獻1記載的是爲了提高彈性恢 復性以複合合成纖維形成吸收材，表面材是以對皮膚形成 良好接觸觸感的棉纖維1 00%所形成。因此，使得表面材 (3) (3)M274925 的親水度高於吸收材，導致形成賦予表面材表面的液體不 易迅速引導到吸收材的構造。 其次，創作專利文獻2記載的內褲襯片是以將單一薄 片的不織布薄片定位在肌膚側，藉此可以低成本製造頻繁 更換衛生用品爲目的。 但是，上述不織布薄片在其內部中人造纖維和聚酯纖 維的調和比是形成均勻分布，不織布薄片內部並未形成親 水度的梯度，並未層有使得賦予不織布薄片的液體迅速吸 引至該不織布薄片內部的考量。因此，肌膚表面側容易因 爲液體持續著濕潤狀態，賦予肌膚乾爽感困難。 因此，上述創作專利文獻2的記載是在上述不織布薄 片的肌膚側表面上形成凹陷部，使賦予該不織布薄片的液 體停留在上述凹陷部的內部，可以提高裝置時的舒適性。 但是上述不織布薄片是以水流的力使得位在其肌膚側表面 的纖維橫向移動形成上述凹陷部，因此不織布薄片的肌膚 側表面在上述凹陷部的周圍部分形成高的纖維密度。使賦 予不織布薄片的液體容易集中在凹陷部周邊殘留，在獲得 對於身體肌膚潤濕感之穿用時的快適性困難。 另外，專利文獻2記載的是含有黏合劑以獲得保持上 述不織布薄片形狀的彈性恢復性。但是，在直接抵接女性 膣周邊的不織布薄片含有黏合劑時對於肌膚的刺激或肌膚 的安全性的面而言並不理想。又，以含黏合劑的不織布所 形成的內褲襯片，由於較部製的襯褲具有更高的剛性，因 此穿著者獲得和襯褲一體的穿用感困難。 (4) (4)M274925 本創作是爲了解決上述習知的課題所硏創而成，提供 具有保液功能的不織布和身體直接抵接的構造，並且具有 對於上述不織布內優異的液體吸引性，液體滯留在肌膚側 表面困難，優異的穿著時的快適性，並且整體形成軟質可 賦予和襯褲呈一體感的內褲襯片爲目的.。 〔解決課題用的手段〕 本創作具有保液薄片及重疊在該保液薄片穿著側的內 面薄片的內褲襯片中，其特徵爲： 上述保液薄片是以不含黏合纖維彼此間的黏合劑，纖 維彼此間經緯交織的1片以上的不織布所形成，該不織布 形成於肌膚側表面，上述保液薄片是以親水性纖維和疏水 性或弱親水性的合成樹脂纖維形成上述肌膚側表面，穿著 側表面至少是以親水性纖維所形成， 上述保液薄片的親水度爲形成於上述穿著側表面層的 一側高於形成於上述肌膚側表面的層。 該內褲襯片是以具有保液功能的不織布所形成的保液 薄片和內面薄片形成基本構成，具有上述保液功能的不織 布形成於肌膚側表面。因此，並未設置以往僅能發揮液體 穿透功能的表面薄片（上薄片）。從女性膣分泌的液體， 並非如以往穿透表面薄片，以上述不織布直接保持，液體 的吸收保持迅速。並且，上述不織布所形成的保液薄片具 有朝著內面薄片提高親水度的親水性梯度，賦予肌膚側表 面的液體迅速地被形成保液薄片的不織布內所吸收。並 -8- (5) M274925 且，液體不容易殘留在位於肌膚側表面的上述不織布的表 面，因此不易造成對於穿著者肌膚的黏滯感，具有穿著時 優異的快適性。 並且，上述不織布不含黏合劑，因此不會造成對肌膚 的刺激對於穿著者的肌膚具安全性。又由於不含黏合劑以 低剛性形成軟質的上述保液薄片，因此容易賦予和襯褲形 成一體的穿著感。並且，上述不織布在肌膚側表面，親水 性纖維和合成樹脂經緯交織，因此不容易產生上述肌膚側 表面的捻絞或突出，容易維持表面形狀。 例如，本創作的上述保液薄片是以1片不織布所形 成，該不織布是以親水性纖維和疏水性或弱親水性的合成 樹脂纖維形成肌膚側表面，穿著側表面至少以親水性纖維 所形成。 此時，以上述不織布的毛細管吸水度是形成於上述穿 著側表面層的一側較形成於上述肌膚側表面層的一側高， 其差値在以上。 以上述1片不織布形成保液薄片時，上述不織布在具 有親水性纖維的下層纖維網上，形成含有上述親水性纖維 和疏水性或者弱親水性的合成樹脂纖維的上層纖維網，將 兩纖維網的纖維一起經緯交織所形成。 以上，以1片不織布形成保液薄片時，以1片不織布 和內面薄片的層疊體爲基本構成製造內褲襯片，因此可形 成低成本的製品。並可薄型化，容易賦予和襯褲形成一體 感。 -9- (6) (6)M274925 爲了可以實現上述薄型化，並可以發揮液體的保持功 能’構成上述保液薄片的上述i片不織布的織物單位面積 重量以50〜12〇g/m2爲佳。 又’本創作中，上述保液薄片是將2片不織布彼此黏 合所構成’形成於肌膚側表面的第1不織布是以親水性纖 維和疏水性或者弱親水性的合成樹脂纖維所形成，位於穿 著側的第2不織布至少是以親水性纖維所形成，可構成上 述第2不織布的毛細管吸水度高於上述第丨不織布，其差 値在1 0mm以上。 此時’第1不織布可發揮防止內褲襯片的肌膚側表面 的捻轉或突出的功能，第2不織布可發揮吸收保持液體的 功能。 並且’本創作中，上述保液薄片爲形成於肌膚側表面 的第1不織布和位在穿著側的第2不織布彼此黏合所構 成， 上述第1不織布是以親水性纖維和疏水性或者弱親水 性的合成樹脂纖維形成上述肌膚側表面，穿著側表面至少 是以親水性纖維所形成，親水度是形成於上述穿著側表面 層的一側較形成於上述肌膚側表面的層高， 上述第2不織布至少是以親水性纖維形成，親水度高 於形成於上述第1不織布的上述穿著側表面的層。 此時，上述第1不織布的毛細管吸水度以形成於上述 穿著側表面層的一側高於形成於上述肌膚側表面的層高， 其差値在1 Oixim以上爲佳，上述第2不織布的毛細管吸水 -10 - (7) M274925 度以高於形成於上述第1不織布的穿著側表面層的毛細管 吸水度’其差値在1 0mm以上爲佳。 此時，上述第1不織布是在具有親水性纖維的下層纖 維網上，形成含有上述親水性纖維和疏水性或者弱親水性 的合成樹脂纖維的上層纖維網，藉著兩纖維網的纖維一起 經緯交織所形成的構成。 如上述，在第1不織布上形成親水度的梯度，並提高 位於其下方的第2不織布的親水度時，可以提高賦予肌膚 側表面的吸引能力，並將液體保持在第2不織布同時增大 液體的保持容量。 此時，上述第 1不織布的織物單位面積重量爲 25〜50g/m2，上述第 2:不織布的織物單位面積重量以 20〜60g/m2爲佳。 並且，本創作重疊上述保液薄片和上述內面薄片彼此 黏合狀態下的格利式織物硬挺度剛性値爲0·7mN以下。 格利式織物硬挺度剛性値在上述値以下時’變得柔 軟，穿著者可以獲得和襯褲一體的穿著感。 又，上述保液薄片和上述內面薄片重疊彼此黏合狀態 下的厚度尺寸爲1mm以下。 本創作的內褲襯片以作爲保液薄片功能的不織布時’ 以內面薄片形成基本構造，可獲得薄型化，而可以構成上 述1mm以下的厚度。 〔新型效果〕 -11 - (8) M274925 本創作的內褲襯片不使用透液用的表面薄片，具 液功能的不織布形成於肌膚側表面’並且該不織布設 水度的梯度’因此可以使賦予內褲襯片肌膚側表面的 迅速地吸入內部’使液體不容易滯留在肌膚側表面。 可形成薄型且軟質物’獲得和襯褲一體的穿著感。並 少構成構件的數量，以低成本量產。 〔實施新型作用的最佳型態〕 第1圖是從肌膚側表面顯示本創作第1實施型態 褲襯片1的上視圖’第2圖爲第1圖的π - Π線的 圖，第3圖是擴大表示上述內褲襯片1的構成，同時 表示液體的吸收功能的擴大剖視圖。 第1圖表示的內褲襯片1沿著縱向中心線〇y方

其周邊的抵接側爲肌膚爲肌膚側表面3，和此相反側爲穿 著側表面。上述本體部1 Q在上述肌膚側表面3是形成保 液薄片1 1。並且，在上述壓花部2將上述保液薄片丨丨從 肌膚側表面3加壓加熱形成凹狀。 如第3圖表示，形成上述保液薄片1 1的1片不織 布，其纖維調和在上層1 5和下層1 6不同。上層1 5是以 親水性纖維及疏水性纖維或者弱親水性的合成樹脂纖爲所 構成。下層1 6含親水性纖維，僅以親水性纖維形成爲 佳。 本說明書中的親水性纖維是意味著法定回潮率爲3 % 以上’並以5 %以上爲佳。疏水性纖維是意味著上述法定 回潮率爲0%。弱親水性纖維的上述法定回潮率小於3%且 不是 〇 %。此外，法定回潮率是相對於放置在2 0 °C相對溼 度6 5 %的外圍環境內時的纖維質量而爲該纖維所吸附的水 分質量的比例（含水率）。 以下，例示上述各纖維及其法定回潮率。以下’在各 纖維名的末尾的括弧內以％記載上述法定回潮率。 (親水性纖維） 植物纖維的棉（8 . 5 % )、紙漿（8 . 5 % )、麻（1 2 % ) 動物纖維的絲（1 2 % ) -13- (10) (10)M274925 再生纖維的人造（11 % )、銅氨纖維（11 % )、波里 諾西客黏膠纖維（虎木棉）（11%) 半合成纖維的醋酯纖維（6 · 5 % ) 合成樹脂纖維的聚醯胺系（例如尼龍（4.5 %

未施以親水化處理的 PET ( 0.4% )、丙烯腈系纖維 (2 % ) 上述實施型態的保液薄片1 1是在形成下層1 6的下層 纖維網的上方重疊形成上層1 5的上層纖維網，對於上述 層疊的纖維網從上層纖維網側施以噴水，使上層纖維網的 纖維彼此間、下層纖維網的纖維彼此間，及上層纖維網的 纖維和下層纖維網的纖維經緯交織，形成1片不織布。並 且，上述保液薄片1 1是藉著纖維間的經緯交織以保持著 薄片形狀，並未使用黏著纖維彼此間的黏合劑 -14- (11) M274925 (binder) 。 例如，上述下層纖維網是以人造6 0質量％及耐久親水 性的ΡΕΤ40質量％所形成的織物單位面積重量40g/m2，上 層纖維網是以棉7 0質量。/〇及弱親水性的P E T 3 0質量％所形 成的織物單位面積重量20g/m2。 第3圖表示的保液薄片1 1示如上述所製造的2層水 針不織布，上層1 5和下層1 6的邊界雖然不明顯，但是保 液薄片1 1的肌膚側表面及位在其附近的上層i 5是以親水 性纖維的棉和P ET所形成，穿著側表面及位在其附近的下 層1 6是以人造和耐久親水性的PET，即僅親水性纖維所 形成。因此相對於上層1 5下層1 6側具有較高的親水度。 即，保液薄片1 1下層1 6的毛細管吸水度較上層1 5高。 上述上層1 5和下層1 6分別的毛細管吸水度是針對上 述保液薄片1 1進行試驗，可以藉著其肌膚側表面和穿著 側表面分別的試驗液的吸引高度的測定來獲得。並且，也 可以僅對於上述上層纖維網’施以和形成保液薄片1 1相 同條件的噴水處理，單獨地形成上層15，同樣地單獨形成 下層1 6，並個別測定各層的毛細管吸水度。 如上述，以人造6 0質量％及耐久親水性的P E T 4 G質 量％所形成織物單位面積重量4 0 g /m 2的不織布’毛細管吸 水度爲80mm，棉70重量％及弱親水性PET30質量％所形 成的織物單位面積重量20g/m2的不織布的毛細管吸水度 爲 6 9 m m 〇 上述保液薄片1 1上層1 5和下層1 6的親水度即毛細 -15- (12) (12)M274925 管吸水度不同，但是其差値小於1 〇 m m時，從上層1 5以 至下層1 6的親水度的梯度變緩，賦予肌膚側表面的液體 朝下層1 6迅速地吸入困難。並且毛細管吸水度的差値大 於100mm時，上層1 5的親水度過低，會降低液體從上層 15吸入下層16的速度。 上述保液薄片1 1的肌膚側表面及上層1 5含有疏水性 或者弱親水性的合成樹脂纖維，因此保液薄片1 1保持著 液體時可以保持肌膚側表面的濕潤強度，肌膚側表面不易 產生破裂。爲此，上層15(形成該上層15用的上述上層 纖維網）以含有20質量％以上的上述合成樹脂纖維爲佳。 並且相對於下層1 6爲了不使上層1 5的親水度極端地降 低，上層1 5的合成樹脂纖維以含有8 5質量％以下爲佳。 上述保液薄片1 1的下層1 6雖然僅以親水性纖維形成 爲佳，但是如上述實施的型態，以下層1 6含耐久親水性 的PET等的合成樹脂纖維爲佳。一旦含有該親水性的合成 樹脂纖維時，吸收保持液體時，不容易產生下層1 6的捻 絞或突出，在構成下層1 6的纖維間容易確保維持著液體 的空間。因此下層1 6以含有2 0質量％以上的上述合成樹 脂纖維爲佳。但是，合成樹脂纖維過多時內褲襯片1的剛 性變得過高，會損及和襯褲間的一體感。因此含於下層1 6 的合成樹脂纖維的上限爲60%。 該內褲襯片1是以1片不織布所形成的保液薄片1 1 和內面薄片12構成其基本構造，在上述保液薄片11的上 層1 5保持著表面強度，使下層1 6發揮液體的吸收保持功 -16- (13) M274925 能。因此將保液薄片 Π的織物單位面積重量設定在 50g/m2以上，小於120g/m2。小於50g/m2時，不能充分發 揮保液能力。並且大於120g/m2時’內褲襯片的厚度變 厚，並增大剛性而不能獲得和襯褲之股部布間的一體感。 上述保液薄片1 1的內部中’由於下層1 6可發揮吸收 保持液體的功能，因此以下層1 6側的織物單位面積重量 大於上層1 5爲佳。 如上述，織物單位面積重量形成50g/m2以上的保液 薄片 11所需的每 1次噴水的處理能量爲 〇.〇9〜0.5 (kw/m2 )，其處理次數以1次以上8次以下爲佳。上述 處理能量（kw/m2 )是以{ 1 ·63 X噴射壓力（kgf/cm2 ) χ 噴射流量（m3/min) } +處理速度（m/min)求得。 噴水噴嘴的開口徑爲70〜120 μ m，對於CD的排列間 距爲0.3〜2.0 mm。例如，每 1次0.2 6 ( k w/m2 )的處理能 量處理6次，設定總計處理能量爲1.56 ( kw/m2)。 將每1次的處理能量設定在上述範圍內時，可以確實 地使50g/m2以上120g/m2的較厚纖維網的纖維經緯交織， 可以維持肌膚側表面濕潤時的表面強度。 上述內面薄片1 2是以聚乙烯薄膜所形成，或者紡黏 型織物不織布（S )和熔噴不織布（Μ )是依S/M/S的順 序層疊黏合成複合不織布所形成。並且內面薄片12以使 用透氣性爲佳。 上述保液薄片Π和內面薄片1 2是藉著熱融形黏著劑 黏著所成。爲了不損及內褲襯片1的柔軟性，上述熱融形 -17- M274925 r 14) 黏著劑的塗層量以5〜30g/m2爲佳。 在上述保液薄片 Π和內面薄片1 2層疊黏著的狀態 下’其總計厚度尺寸在1 mm以下。並且縱向和橫向的格 利式織物硬挺度同樣在〇.7mN以下。厚度在lmm以下， 格利式織物硬挺度在〇.7mN以下時，黏著在襯褲的股布部 使用時，不會損及襯褲的變形，獲得和襯褲間的一體感。 上述感壓黏著劑層1 3在內面薄片1 2的表面形成縱向 平行延伸的條子狀。上述感壓黏著劑層i 3只要使內褲襯 片1相對於襯褲的股布部內面不位移地固定，任意的模樣 皆可，例如也可以橫向平行延伸的條子形狀，也可以塗抹 在內面薄片12的表面前面。內面薄片12以具有透氣性的 樹脂薄膜形成時，爲了不妨礙其透氣性以條子、模樣爲佳。 並且剝離型薄片2 0是使用在紙材表面塗抹剝離劑。 上述內褲襯片1是藉上述感壓黏著劑層13黏著在襯 褲的股布部內面安裝。該內褲襯片1 1由於僅以保液薄片 11和內面薄片12爲基本構成，製造容易可以低成本量 產。並且厚度在 lmm以下，格利式織物硬挺度在 〇.7mN 以下，因此可以追隨襯褲的股布部而變形，穿著者可以感 覺內褲襯片形成如襯褲織股布部的一部份。 具有液體吸收保持功能的上述保液薄片1 1直接抵接 女性的膣口及其周邊，膣排泄物等直接賦予保液薄片11 的肌膚側表面。如以往吸收材的表面以薄的表面材覆蓋的 構造時，賦予肌膚側表面的液體穿透表面材被導入吸收材 內，因此增加液體的吸收速度有限。但是，上述內褲襯片 -18- (15) (15)M274925 1液體無須經由表面材可以直接賦予保液薄片1 1，因此可 增速液體的吸收。 此外，保液薄片1 1不含黏合劑，液體在纖維間的移 動不會爲黏合劑所阻礙。並且，下層1 6側較上層1 5具有 更高的親水度，因此如第3圖的模式所示，液體2 5可迅 速穿透上層1 5吸入下層1 6，在下層1 6中擴散，保持於下 層1 6。藉著上層1 5和下層1 6的親水度的梯度，可加速液 體2 5的吸收，上層1 5不容易殘留液體，因此肌膚側表面 對肌膚不易產生黏稠感，可以獲得穿著時的快適感。 並且，直接抵接肌膚的保液薄片1 1不含黏合劑，因 此對於肌膚安全。 第4圖是表示本發明第· 2實施型態的內褲襯片3 0的 剖視圖，第5圖是表不擴大上述內裤襯片3 0的構成，同 時模式表示液體吸收功能的擴大剖視圖。 該內褲襯片30的形狀式和第1圖表示的第1實施型 態相同。本體部40是以保液薄片3 1和內面薄片1 2及感 壓黏著劑層1 3所形成。另外，省略剝離型薄片2 0的圖 示。內面薄片1 2、感壓黏著劑層1 3及剝離形薄片2 0是和 上述第1實施型態相同。 該內褲襯片3 0的保液薄片3 1是以第1不織布3 2和 第2不織布3 3所構成，第1不織布3 2是形成於肌膚側表 面，第2不織布3 3是位在穿著側。第1不織布3 2和第2 不織布3 3是藉熱融型黏著劑黏著。熱融型黏著劑的塗抹 量不會妨礙從第1不織布3 2朝第2不織布3 3的液體的通 -19- (16) M274925 過，並設定5〜30 g/m2不妨礙內褲襯片30整體軟質感的範 圍內。又，黏著第2不織布33和內面薄片12之間的熱融 型黏著劑的塗抹量相同。 內褲襯片3 0的厚度在1 mm以下，格利式織物硬挺度 在縱向和橫向同樣是0.7 mN以下。 上述第1不織布3 2是以親水性纖維漢書水性或者弱 親水性的合成樹脂纖維所形成。上述第2不織布3 3只以 親水性纖維形成。第1不織布3 2爲了維持內褲襯片3 0的 肌膚側表面3的表面強度，以含有2 0〜8 5質量％的上述合 成樹脂纖維爲佳。第2不織布3 3可只以植物纖維或再生 纖維形成’也可以在內褲襯片3 0整體的剛性不增高的範 圍內含有親水性的合成樹脂纖維。 本實施型態中，第1不織布32含有棉70質量％和30 質量％的弱親水性PET，織物單位面積重量爲30g/m2的水 針不織布。藉噴水的能量每1次爲0.16( kw/m2 )，使用 進行6次處理。總計的處理能量爲ο·% ( kw/m2 )。 上述第2不織布3 3爲人造纖維1 〇 〇 %，織物單位面積 重量爲25g/m2的水針不織布。藉噴水的能量每1次爲 0.16( kw/m2 ) ’使用進行3次處理。總計的處理能量爲 0.48 ( kw/m2) 〇 藉著第1不織布3 3的處理能量的增高，可以提高第1 不織布3 2纖維的經緯交織，提高濕潤時肌膚側表面3的 表面強度。另一方面，使第2不織布3 3的處理能量低於 第1不織布3 2 ’在第2不織布3 3內可確保在纖維間保持 -20- (17) M274925 液體用的間隙，以確保液體的吸收容量。 毛細管吸水度是第2不織布較第1不織布高，其差値 在10mm以上。該實施的型態中，保液薄片31是如第1 實施的型態並非雙層水針不織布，而是黏合不同的不織布 3 2、3

Description of the new type [Technical field to which the new type belongs] This creation is about a thin and soft panty liner that can give a sense of unity to the panty, especially on the skin side surface, it is not easy for the liquid to diffuse and it can play the liquid quickly Panty liner for inhalation. [Prior art] The panty liner is used on the inner side of the femoral part of the panty on days other than the physiological day of women, and is used to absorb menstrual secretions such as menstruation. This panty liner is thin and soft that provides a sense of unity with the panties, and has the ability to hold liquids such as urinary secretions, and it is expected that the liquid will not easily spread to the skin-side surface. The panty liner described in the following Japanese Creative Patent Document 1 has a structure in which the surface side covers the skin-side surface of the absorbent material. The absorbent material is a hydrophilic nonwoven fabric made of composite synthetic fiber having a fabric unit area weight of about 40 g / m2. The surface material is a non-woven fabric formed by 100% cotton fibers and a water jet wefting method, and a material thinner than the absorbent material is used. This panty liner absorbs and retains liquid in the absorbent material, and the surface material is not a thick material capable of retaining liquid, but has a function of allowing liquid to penetrate into the absorbent material. Therefore, a plurality of liquid-pervious holes for guiding the liquid to the absorbent material are formed in the surface material. The panty liner described in the following Japanese Creative Patent Document 2 is a single non-woven fabric. The cloth sheet is positioned on the skin side and has a liquid-impermeable barrier on the wearing side. The non-woven fabric sheet is a card-shaped mixed rayon and polyester fiber -5- (2) M274925-dimensional fiber web, and the fibers are woven by warp and weft using a water jet from a nozzle. In addition, the above-mentioned water flow causes the fibers on the surface of the nonwoven fabric sheet to move laterally to form a recessed portion. Furthermore, an adhesive solution is provided between the non-woven sheet's and the adhesive fibers, while maintaining the shape of the recessed portion, and improving the elastic recovery function during compression. [Creative Patent Document 1] Japanese Patent Laid-Open No. 8-2 4 2 8 9 [Creative Patent Document 2] Japanese Patent Laid-Open No. 7-1 3 8 8 6 5 [New Content] [New Type of Problems to be Solved] The above-mentioned Creative Patent Document 1 describes that a conventional panty liner covers the surface of an absorbent material with a surface material, makes the fiber density on the skin side surface dense, and does not easily cause cracks on the skin side surface when the liquid is applied. In addition, the surface material forms liquid-permeable holes, and the liquid imparted to the surface material is guided from the liquid-permeable holes to the absorbent material below it. However, in the structure in which the absorbent material is covered with the surface material, it is not easy to quickly guide liquids such as sputum secretions imparted to the surface material to the absorbent material, and the liquid is liable to stay on the surface material. When the opening area ratio of the liquid-permeable holes formed in the surface material is increased to quickly guide the liquid imparted to the surface material to the absorbent material, the liquid absorbed and held in the absorbent material easily leaks out of the surface of the surface material due to body pressure. In addition, the above-mentioned Creation Patent Document 1 describes that composite synthetic fibers are used to form an absorbent material in order to improve elastic resilience, and that the surface material is formed of 100% of cotton fibers that provide a good touch to the skin. Therefore, the surface material (3) (3) M274925 is made more hydrophilic than the absorbent material, resulting in a structure in which the liquid imparted to the surface material is not easily guided to the absorbent material. Next, the panty liner described in Creation Patent Document 2 is aimed at positioning a single thin non-woven sheet on the skin side, thereby enabling low-cost manufacturing of frequent replacement of sanitary products. However, the blending ratio of the artificial fiber and the polyester fiber in the above-mentioned nonwoven sheet is uniformly distributed. There is no gradient of hydrophilicity formed in the nonwoven sheet, and no liquid is imparted to the nonwoven sheet to attract the nonwoven sheet quickly. Internal considerations. Therefore, it is easy for the surface of the skin to keep the liquid moisturized, making it difficult to give the skin a dry feeling. Therefore, it is described in the above-mentioned Creative Patent Document 2 that a recessed portion is formed on the skin-side surface of the nonwoven fabric sheet, and the liquid imparted to the nonwoven fabric sheet stays inside the recessed portion, thereby improving the comfort during the device. However, the non-woven sheet is formed by moving the fibers located on the skin side surface laterally by the force of water flow to form the recessed portion. Therefore, the skin side surface of the non-woven sheet forms a high fiber density in the peripheral portion of the recessed portion. The liquid imparted to the non-woven fabric sheet is easily concentrated and left around the recessed portion, and it is difficult to quickly adapt to wear on the body with a moisturizing feeling. In addition, Patent Document 2 describes that an adhesive is contained to obtain elastic restorability that maintains the shape of the nonwoven fabric sheet. However, when the non-woven sheet directly abutting the periphery of a woman's hairpin contains an adhesive, it is not ideal for the skin irritation or the safety of the skin. In addition, underpants formed of an adhesive-containing non-woven fabric have higher rigidity than those made of underpants, making it difficult for the wearer to obtain a feeling of being integrated with the underpants. (4) (4) M274925 This creation was created in order to solve the above-mentioned conventional problems, and provides a structure in which the non-woven fabric with a liquid retention function directly contacts the body, and has excellent liquid attraction to the above-mentioned non-woven fabric. The liquid is difficult to stay on the skin side surface, and has excellent fastness when worn, and the overall formation of a soft underpants lining that can give a sense of integration with the underpants. . [Means for Solving the Problem] In the present invention, a panty liner having a liquid-retaining sheet and an inner sheet superimposed on the wearing side of the liquid-retaining sheet is characterized in that the liquid-retaining sheet is bonded with no adhesive fibers Agent, the fiber is formed by one or more non-woven fabrics interwoven with warp and weft between the fibers, the non-woven fabric is formed on the skin side surface, and the liquid retaining sheet is formed by the hydrophilic fiber and the hydrophobic or weakly hydrophilic synthetic resin fiber, The wear-side surface is formed of at least hydrophilic fibers, and the hydrophilicity of the liquid-retaining sheet is such that the layer formed on the wear-side surface layer is higher on the skin-side surface layer. This panty liner is basically composed of a liquid-retaining sheet and a back sheet formed of a nonwoven fabric having a liquid-retaining function, and a nonwoven fabric having the liquid-retaining function is formed on the skin-side surface. Therefore, a surface sheet (upper sheet) that has conventionally only exhibited a liquid penetrating function is not provided. The liquid secreted from the female diarrhea does not penetrate the surface sheet as before, and is directly held by the aforementioned non-woven fabric, and the liquid absorption is maintained rapidly. In addition, the liquid-retaining sheet formed by the nonwoven fabric has a hydrophilic gradient that increases the hydrophilicity toward the inner sheet, and the liquid imparted to the skin-side surface is quickly absorbed by the nonwoven fabric forming the liquid-retaining sheet. And -8- (5) M274925 Furthermore, the liquid does not easily remain on the surface of the non-woven fabric located on the skin side surface, so it is not easy to cause stickiness to the wearer's skin, and has excellent fastness when worn. In addition, the non-woven fabric does not contain an adhesive, so it does not cause skin irritation and is safe for the wearer's skin. In addition, since the soft liquid-retaining sheet is formed with low rigidity without an adhesive, it is easy to impart a feeling of wearing integrated with the panty. In addition, since the non-woven fabric is intertwined with hydrophilic fibers and synthetic resin warp and weft on the skin-side surface, twists or protrusions on the skin-side surface are unlikely to occur, and the surface shape is easily maintained. For example, the above-mentioned liquid-retaining sheet of the present invention is formed by one non-woven fabric. The non-woven fabric uses hydrophilic fibers and hydrophobic or weakly hydrophilic synthetic resin fibers to form the skin side surface, and the wearing side surface is formed of at least hydrophilic fibers. . At this time, the capillary absorbency of the nonwoven fabric is higher on the side formed on the penetrating-side surface layer than on the side formed on the skin-side surface layer, and the difference is more than that. When the liquid-retentive sheet is formed from the one nonwoven fabric, the nonwoven fabric forms an upper fibrous web containing the hydrophilic fibers and a hydrophobic or weakly hydrophilic synthetic resin fiber on the lower fibrous web having hydrophilic fibers, and the two fibrous webs are formed. The fibers are formed by interlacing warp and weft. As described above, when the liquid-retaining sheet is formed of a single nonwoven fabric, a panty liner is produced by using a laminated body of a single nonwoven fabric and an inner surface sheet as a basic structure, so that a low-cost product can be formed. In addition, it can be made thin, and it is easy to provide a sense of unity with the underpants. -9- (6) (6) M274925 In order to achieve the above-mentioned thinness and to perform the function of retaining liquid, the weight per unit area of the fabric of the i-piece nonwoven fabric constituting the liquid-retaining sheet is preferably 50 to 120 g / m2. . Also, in this creation, the above liquid-retaining sheet is formed by bonding two nonwoven fabrics to each other. The first nonwoven fabric formed on the side surface of the skin is formed of hydrophilic fibers and hydrophobic or weakly hydrophilic synthetic resin fibers, and is located in the wear. The second non-woven fabric on the side is formed of at least hydrophilic fibers, and the capillary absorbency of the second non-woven fabric can be higher than that of the second non-woven fabric, and the difference is more than 10 mm. In this case, the 'first nonwoven fabric has a function of preventing twisting or protruding of the skin-side surface of the panty liner, and the second nonwoven fabric has a function of absorbing and retaining liquid. In addition, in this creation, the liquid-retaining sheet is composed of a first non-woven fabric formed on the skin side surface and a second non-woven fabric on the wearing side. The first non-woven fabric is made of hydrophilic fibers and hydrophobic or weakly hydrophilic. The synthetic resin fibers form the skin-side surface, and the wearing-side surface is formed of at least hydrophilic fibers. The hydrophilicity is formed on the side of the wearing-side surface layer that is higher than the layer formed on the skin-side surface. The second non-woven fabric It is formed of at least hydrophilic fibers and has a higher degree of hydrophilicity than the layer formed on the wearing side surface of the first nonwoven fabric. At this time, the water absorption of the capillary of the first non-woven fabric is higher than that of the layer formed on the skin-side surface of the wearing-side surface layer, and the difference is preferably 1 Oixim or more. The capillary of the second non-woven fabric Water absorption -10-(7) M274925 is preferably higher than the capillary water absorption 'of the capillary formed on the wearing side surface layer of the first nonwoven fabric, and the difference is preferably 10 mm or more. At this time, the first non-woven fabric is formed on the lower web having hydrophilic fibers to form an upper web including the hydrophilic fibers and synthetic resin fibers that are hydrophobic or weakly hydrophilic, and the fibers of the two webs are warped and wefted together. Interlaced formation. As described above, when a gradient of hydrophilicity is formed on the first nonwoven fabric, and the hydrophilicity of the second nonwoven fabric underneath is increased, the suction ability given to the skin side surface can be increased, and the liquid can be kept on the second nonwoven fabric while increasing the liquid. Holding capacity. At this time, the basis weight of the first nonwoven fabric is 25 to 50 g / m2, and the basis weight of the second nonwoven fabric is preferably 20 to 60 g / m2. In addition, in this work, the stiffness of the Gurley fabric in the state where the liquid-retaining sheet and the inner-surface sheet are bonded to each other is not more than 0.7 mN. When the stiffness of the Gurley fabric is not more than the above, it becomes soft, and the wearer can obtain a feeling of being integrated with the underpants. The thickness dimension of the liquid-retaining sheet and the inner-surface sheet in an overlapped state is 1 mm or less. When the panty liner of the present invention is a non-woven fabric that functions as a liquid-retaining sheet, a basic structure is formed by the inner sheet, and the thickness can be reduced to a thickness of 1 mm or less. [New effect] -11-(8) M274925 The panty liner of this creation does not use a liquid-permeable surface sheet, and a non-woven fabric with a liquid function is formed on the skin side surface 'and the non-woven fabric is provided with a gradient of water' so that The rapid inhalation of the inner side of the skin side surface of the panty liner prevents liquid from remaining on the skin side surface easily. It can be formed into a thin and soft material 'to obtain a wearing feeling integrated with the underpants. The number of components is reduced, and mass production is performed at low cost.

Fig. 2 is a π-Π line of Fig. 1. FIG. 3 is an enlarged cross-sectional view showing the structure of the underwear liner 1 in an enlarged manner and showing a liquid absorption function.

The longitudinal edge portion 1 a and the rear edge portion 1 b face forward and rearward. The curved shape is convex, and the right edge portion 1 c and the left edge portion 1 d are curved in a concave shape in the lateral direction. An embossed portion 2 is formed inside the front edge portion 1 a, the rear edge portion 1 b, and the left and right side edge portions 1 c. The embossed portion 2 is compressed from the skin-side surface to form a concave shape. This embodiment is a pattern in which the embossed portion 2 expresses a predetermined pattern. As shown in FIG. 2, “the main body of the panty liner 1 is a liquid-retaining sheet 11 formed of a non-woven fabric, and an inner surface sheet 12 superimposed on the liquid-retaining sheet 1 and a pressure sensitive surface formed on the inner surface sheet 11 Adhesive X, which retains the lyophilic and can reduce the direction of the internal cross-sectional mode, is composed of a ° Id linear shape, Id heated out of a pre-sheet 1 top agent layer -12- M274925 1 3, and in the above body 10 On the inner surface, a peeling sheet 20 is superposed and adhered to protect the pressure-sensitive adhesive layer 13. The main body part 10 of the panty liner 1 is between the interfemoral part of a woman, and the contact side of 膣 and its periphery is the skin-side surface 3, and the opposite side is the wear-side surface. The body portion 1Q is a liquid-retaining sheet 11 formed on the skin-side surface 3. Then, in the embossing section 2, the liquid-retaining sheet 丨 is pressed and heated from the skin-side surface 3 to form a concave shape. As shown in Fig. 3, the fibers of the single nonwoven fabric forming the liquid-retaining sheet 11 are different in the upper layer 15 and the lower layer 16. The upper layer 15 is composed of hydrophilic fibers and hydrophobic fibers or weakly hydrophilic synthetic resin fibers. The lower layer 16 contains hydrophilic fibers, and it is preferable to form only the hydrophilic fibers. The hydrophilic fiber in this specification means that the legal moisture regain is 3% or more 'and preferably 5% or more. Hydrophobic fibers mean that the legal moisture regain is 0%. The aforementioned legal moisture regain of weakly hydrophilic fibers is less than 3% and not 0%. In addition, the legal moisture regain is the ratio (water content) of the mass of water absorbed by the fiber relative to the mass of the fiber when placed in an external environment with a relative humidity of 65% at 20 ° C. Below, the above-mentioned fibers and their legal moisture regains are exemplified. Hereinafter, the above-mentioned legal moisture regain is described in% in parentheses at the end of each fiber name. (Hydrophilic fiber) cotton of plant fiber (8. 5%), pulp (8. 5%), hemp (12%) silk of animal fibers (12%) -13- (10) (10) M274925 artificial (11%) of recycled fiber, copper ammonia fiber (11%), polynosic Viscose fiber (Tiger cotton) (11%) Semi-synthetic acetate fiber (6.5%) Polyamide based synthetic resin fiber (such as nylon (4. 5%)) 'Polyvinyl alcohol (such as polyvinyl acetal fibers (5%), etc., hydrophilic groups with hydroxyl, amino, carboxymethyl, etc., others are PP (polypropylene), PE (polyethylene), Synthetic resin fibers formed from PET (polyethylene terephthalate), etc., are coated or kneaded with a hydrophilizing agent such as a surfactant, or the surface is formed into an uneven shape or a porous shape to improve the water retention capacity. Hydrophobic fibers) PP (0%), PE (0%) (weakly hydrophilic fibers) without hydrophilization, PET (0. 4%), acrylonitrile-based fibers (2%) The liquid-retaining sheet 11 of the above embodiment is an upper-layer fibrous web in which an upper layer 15 is formed on top of the lower-fiber web forming the lower layer 16; Water spray is applied from the upper fiber web side, so that the fibers of the upper fiber web, the fibers of the lower fiber web, and the fibers of the upper fiber web and the fibers of the lower fiber web are interwoven with each other to form a piece of non-woven fabric. In addition, the liquid-retaining sheet 11 is interwoven with the warp and weft of the fibers to maintain the sheet shape, and no adhesive is used to adhere the fibers to each other -14- (11) M274925 (binder). For example, the above-mentioned lower fiber web is a fabric having a weight per unit area of 40 g / m2 formed of 60% by mass of artificial and 40% by weight of PET, and the upper fiber web is 70% by mass of cotton. The weight per unit area of the fabric formed by the low-hydrophilic P E T 3 0 mass% was 20 g / m2. The liquid-retaining sheet 11 shown in FIG. 3 shows the two-layer water needle nonwoven fabric manufactured as described above. Although the boundary between the upper layer 15 and the lower layer 16 is not obvious, the skin-side surface of the liquid-retaining sheet 11 and its vicinity are located there. The upper layer i 5 is made of cotton with hydrophilic fibers and PET, and the wearing side surface and the lower layer 16 near it are made of artificial and durable hydrophilic PET, that is, only hydrophilic fibers. Therefore, compared with the upper layer 15 and the lower layer 16 side, it has higher hydrophilicity. In other words, the liquid-retaining sheet 11 has a higher capillary water absorption in the lower layer 16 than in the upper layer 15. The capillary water absorption of the upper layer 15 and the lower layer 16 is tested for the liquid-retaining sheet 11 described above, and can be obtained by measuring the suction height of the test liquid on the skin-side surface and the wearing-side surface, respectively. Alternatively, the upper fiber web 'may be subjected to a water spraying treatment under the same conditions as the formation of the liquid-retaining sheet 11 to form the upper layer 15 alone and the lower layer 16 in the same manner, and the capillary water absorption of each layer may be measured individually. As described above, the nonwoven fabric with a basis weight of 40 g / m 2 made of artificial 60% by mass and durable hydrophilic PET 4 G% by mass has a capillary water absorption of 80mm, cotton 70% by weight, and weakly hydrophilic PET30. % The capillary water absorption of the non-woven fabric with a basis weight of 20 g / m2 is 6 9 mm. 〇The liquid-retaining sheet 1 1 has a hydrophilicity of the upper layer 15 and the lower layer 16 which are capillary -15- (12) (12) M274925 The water absorption of the tube is different, but when the difference is less than 10 mm, the gradient of the hydrophilicity from the upper layer 15 to the lower layer 16 becomes slower, and it is difficult to quickly inhale the liquid imparted to the skin side toward the lower layer 16. In addition, when the difference in capillary water absorption is greater than 100 mm, the hydrophilicity of the upper layer 15 is too low, which will reduce the speed at which the liquid is drawn into the lower layer 16 from the upper layer 15. The skin-side surface and the upper layer 15 of the liquid-retaining sheet 1 1 contain hydrophobic or weakly hydrophilic synthetic resin fibers. Therefore, the liquid-retaining sheet 11 can maintain the wet strength of the skin-side surface while holding the liquid, and the skin-side surface is unlikely to be generated rupture. For this reason, the upper layer 15 (the above-mentioned upper fiber web for forming the upper layer 15) preferably contains the synthetic resin fiber in an amount of 20% by mass or more. In addition, in order to prevent the hydrophilicity of the upper layer 15 from being extremely reduced with respect to the lower layer 16, the synthetic resin fibers of the upper layer 15 should preferably contain 85 mass% or less. Although the lower layer 16 of the liquid-retaining sheet 11 is preferably formed of only hydrophilic fibers, as in the embodiment described above, the lower layer 16 preferably contains synthetic resin fibers such as durable hydrophilic PET. When the hydrophilic synthetic resin fiber is contained, when the liquid is absorbed and retained, twists or protrusions of the lower layer 16 are less likely to occur, and a space for maintaining a liquid is easily ensured between the fibers constituting the lower layer 16. Therefore, the lower layer 16 preferably contains the above-mentioned synthetic resin fiber in an amount of 20% by mass or more. However, when there are too many synthetic resin fibers, the rigidity of the panty liner 1 becomes too high, and the sense of unity with the panty is impaired. Therefore, the upper limit of the synthetic resin fiber contained in the lower layer 16 is 60%. The panty liner 1 is composed of a liquid-retaining sheet 11 and an inner sheet 12 formed of one non-woven fabric. The upper layer 15 of the liquid-retaining sheet 11 maintains surface strength and the lower layer 16 is liquid. Absorption and holding function -16- (13) M274925 Yes. Therefore, the fabric basis weight of the liquid-retaining sheet Π is set to be more than 50 g / m2 and less than 120 g / m2. When it is less than 50 g / m2, the liquid holding capacity cannot be fully exerted. When the thickness is more than 120 g / m2, the thickness of the panty liner becomes thicker and the rigidity is increased, so that a sense of unity with the leg cloth of the panty cannot be obtained. Since the lower layer 16 has a function of absorbing and retaining liquid in the inside of the liquid-retaining sheet 11, the basis weight of the fabric on the lower layer 16 side is preferably greater than the upper layer 15. As described above, the treatment energy required for each water spray to form the liquid-retaining sheet 11 with a basis weight of 50 g / m2 or more is 0.001. 〇9 ~ 0. 5 (kw / m2), and the number of treatments is preferably from 1 to 8 times. The above processing energy (kw / m2) is obtained by {1 · 63 X injection pressure (kgf / cm2) χ injection flow rate (m3 / min)} + processing speed (m / min). The opening diameter of the water spray nozzle is 70 ~ 120 μm, and the arrangement interval for the CD is 0. 3 ~ 2. 0 mm. For example, every time 0. The processing energy of 2 6 (k w / m2) is processed 6 times, and the total processing energy is set to 1. 56 (kw / m2). When the energy per treatment is set within the above-mentioned range, the fibers of the thick fiber web having a thickness of 50 g / m2 or more and 120 g / m2 or more can be surely interwoven with each other, and the surface strength when the skin-side surface is wet can be maintained. The inner sheet 12 is formed of a polyethylene film, or the spunbond nonwoven fabric (S) and the meltblown nonwoven fabric (M) are laminated and bonded to a composite nonwoven fabric in the order of S / M / S. In addition, the inner surface sheet 12 is preferably used in air permeability. The above-mentioned liquid-retaining sheet Π and the inner surface sheet 12 are adhered by a hot-melt adhesive. In order not to impair the softness of the panty liner 1, the coating amount of the above-mentioned hot melt -17- M274925 r 14) adhesive is preferably 5 to 30 g / m2. In a state where the above-mentioned liquid-retaining sheet Π and the inner-surface sheet 12 are laminated and adhered, their total thickness dimension is 1 mm or less. And the stiffness of the Gurley fabric in the longitudinal and transverse directions is also at 0.1. 7mN or less. The thickness is below lmm, the stiffness of the Gurley fabric is 〇. When it is less than 7mN, it can be adhered to the pants of the underpants, and the deformation of the underpants will not be damaged when used, and a sense of unity with the underpants will be obtained. The pressure-sensitive adhesive layer 13 is formed in a strip shape extending in parallel in the longitudinal direction on the surface of the inner surface sheet 12. The pressure-sensitive adhesive layer i 3 may be any shape as long as the panty liner 1 is fixed to the inner surface of the panty portion of the panty without any displacement. For example, it may be a strip shape extending horizontally in parallel, or it may be applied to the inner sheet 12 surface front. When the inner surface sheet 12 is formed of a resin film having air permeability, a sliver or pattern is preferable so as not to impede the air permeability. In addition, the release sheet 20 uses a release agent applied to the surface of the paper. The underpants lining sheet 1 is attached to the inner surface of the undergarment portion of the underpants by the pressure-sensitive adhesive layer 13. Since the underpants lining sheet 11 is basically composed of only the liquid-retaining sheet 11 and the inner sheet 12, it can be easily manufactured and mass-produced at low cost. And the thickness is below 1mm, the stiffness of the Gurley fabric is 〇. Below 7mN, it can be deformed following the panty portion of the panty, and the wearer can feel that the panty lining piece forms a part of the panty knitted portion. The above-mentioned liquid-retaining sheet 11 having the function of liquid absorption and retention directly abuts a woman's mouth and its surroundings, and excrement or the like is directly given to the skin-side surface of the liquid-retaining sheet 11. As in the conventional structure in which the surface of the absorbent material is covered with a thin surface material, the liquid that imparts to the skin-side surface penetrates the surface material and is introduced into the absorbent material, so the rate of increase in liquid absorption is limited. However, the above-mentioned panty liner -18- (15) (15) M274925 1 liquid can be directly imparted to the liquid-retaining sheet 11 without going through the surface material, so that the liquid absorption can be increased. In addition, the liquid-retaining sheet 11 does not contain a binder, and the movement of liquid between fibers is not hindered by the binder. In addition, the lower layer 16 has a higher hydrophilicity than the upper layer 15. Therefore, as shown in the pattern in FIG. 3, the liquid 25 can quickly penetrate the upper layer 15 and suck into the lower layer 16 and diffuse in the lower layer 16 to maintain.于 下层 16。 6 in the lower layer. The gradient of the hydrophilicity of the upper layer 15 and the lower layer 16 can accelerate the absorption of the liquid 25, and the upper layer 15 is not easy to retain liquid. Therefore, the skin side surface is not easy to produce a sticky feeling to the skin, and a pleasant feeling during wearing can be obtained. In addition, since the liquid-retaining sheet 11 which directly touches the skin does not contain an adhesive, it is safe for the skin. Fig. 4 is a cross-sectional view showing a panty liner 30 according to the second embodiment of the present invention, and Fig. 5 is a diagram showing an enlarged cross-sectional view of the panty liner 30, while the mode is an enlarged cross-sectional view showing a liquid absorption function. The shape of the panty liner 30 is the same as that of the first embodiment shown in Fig. 1. The main body portion 40 is formed of a liquid holding sheet 31, an inner surface sheet 12 and a pressure-sensitive adhesive layer 13. In addition, the illustration of the peelable sheet 20 is omitted. The inner sheet 1 2, the pressure-sensitive adhesive layer 13 and the release sheet 20 are the same as those in the first embodiment. The liquid-retaining sheet 3 1 of the panty liner 30 is composed of a first nonwoven fabric 3 2 and a second nonwoven fabric 3 3. The first nonwoven fabric 3 2 is formed on the skin side surface, and the second nonwoven fabric 33 is located on the wearing side. . The first nonwoven fabric 3 2 and the second nonwoven fabric 3 3 are adhered by a hot-melt adhesive. The application amount of the hot-melt adhesive will not prevent the passage of liquid from the first nonwoven fabric 3 2 to the second nonwoven fabric 3 3-19 (16) M274925, and set 5 ~ 30 g / m2 without hindering the panty liner 30 Within the overall soft texture. In addition, the amount of the hot-melt adhesive applied between the second nonwoven fabric 33 and the inner surface sheet 12 is the same. The thickness of the panty liner 30 is less than 1 mm, and the stiffness of the Gurley fabric is also 0 in the longitudinal and transverse directions. 7 mN or less. The first non-woven fabric 32 is formed of a hydrophilic fiber Hanshu water-soluble or weakly hydrophilic synthetic resin fiber. The second non-woven fabric 33 is formed of only hydrophilic fibers. In order to maintain the surface strength of the skin-side surface 3 of the panty liner 30, the first nonwoven fabric 3 2 preferably contains 20 to 85 mass% of the synthetic resin fibers. The second non-woven fabric 3 3 may be formed of only plant fibers or regenerated fibers' or may contain hydrophilic synthetic resin fibers within a range where the overall stiffness of the panty liner 30 is not increased. In this embodiment, the first non-woven fabric 32 contains water-wet PET of 70% by mass and 30% by mass of cotton, and a water needle nonwoven fabric having a basis weight of 30 g / m2. The energy of borrowing water is 0 every time. 16 (kw / m2), use 6 times for processing. The total processing energy is ο ·% (kw / m2). The second non-woven fabric 33 is a water-jet needle-woven non-woven fabric with 100% of rayon and a basis weight of 25 g / m2. The energy of the water spray is 0 every time. 16 (kw / m2) 'is used for three times. The total processing energy is 0. 48 (kw / m2) 〇 By increasing the processing energy of the first non-woven fabric 3 3, the warp and weft interweaving of the first non-woven fabric 3 2 fibers can be increased, and the surface strength of the skin side surface 3 when wet is increased. On the other hand, the processing energy of the second non-woven fabric 3 3 is lower than that of the first non-woven fabric 3 2 ′. In the second non-woven fabric 3 3, it is ensured that -20- (17) M274925 liquid gap is maintained between the fibers to ensure the liquid Absorptive capacity. The water absorption of the capillary is higher than that of the first nonwoven fabric, and the difference is 10 mm or more. In this embodiment, the liquid-retaining sheet 31 is the same as in the first embodiment. It is not a double-layer water-jet non-woven fabric, but different non-woven fabrics 3 2 and 3 3. Therefore, the difference in the capillary absorption rate can be quickly obtained by liquid More preferably, it is 20 mm or more which penetrates the boundary surface of the 1st nonwoven fabric 32 and the 2nd nonwoven fabric 33. In the embodiment described above, the capillary water absorption of the first nonwoven fabric 32 is 69 mm, and the capillary water absorption of the second nonwoven fabric 33 is 113 mm, with a difference of 40 mm or more. The upper limit is 100 mm. The basis weight of the first nonwoven fabric 32 is 25 to 5 Og / m2. When it is smaller than the above range, the wet strength of the skin side surface cannot be increased. When it exceeds the above range, the liquid imparted to the skin side surface 3 tends to stay on the first nonwoven fabric 32 and cannot penetrate into the second nonwoven fabric 3 3 quickly. The fabric basis weight of the second nonwoven fabric 3 3 is 33 to 6 Og / m 2. When it is smaller than the above range, the liquid holding capacity cannot be sufficiently ensured. When it exceeds the above range, the rigidity of the panty liner 30 is increased. The total fabric basis weight of the liquid-retaining sheet 3 1 composed of the first nonwoven fabric 3 2 and the second nonwoven fabric 33 is 45 to 110 g / m 2. This panty liner 30 is enlarged, as shown in Fig. 5, and the liquid 25 imparted to the skin-side surface 3 is attracted by the hydrophilicity of the second nonwoven fabric 33, and is quickly worn through the first nonwoven fabric 32. The liquid 25 is held inside the second nonwoven fabric 3 3. Therefore, the liquid does not easily remain on the skin side surface 3, and it is difficult to impart a sticky feeling to the skin. Fig. 6 is an enlarged cross-sectional view showing the liquid absorbing function of the panty liner 50 according to the third embodiment of the present invention, and the expanded -21-(274) M274925 is shown in a schematic form. The shape of the panty liner 50 is related to the shape of the first embodiment shown in FIG. The main body portion 60 is formed of the liquid-retaining sheet 51 and the inner surface sheet 12 and the pressure-sensitive adhesive layer 13. The illustration of the release sheet 20 is omitted. The inner surface sheet 12, the pressure-sensitive adhesive layer 13, and the release type sheet 20 are the same as those of the above-mentioned one-step application. The liquid-retaining sheet 51 of the panty liner 50 is composed of a first non-woven fabric 5 2 and a second non-woven fabric 53. The first non-woven fabric 5 2 is formed on the skin side surface 3 and the second non-woven fabric 53 is placed on the wearer. side. The i-th non-woven fabric 5 2 and the second non-woven fabric 5 3 are adhered by a hot-melt adhesive. The amount of the hot-melt adhesive does not hinder the passage of liquid from the first nonwoven fabric 52 to the second nonwoven fabric 53, and is set within a range of 5 to 30 g / m2 so as not to hinder the overall soft texture of the panty liner 30. The amount of the hot-melt adhesive to be applied between the second nonwoven fabric 53 and the inner surface sheet 12 is the same. The thickness of the panty liner 50 is less than 1 mm, and the stiffness of the Gurley fabric is 0 in the longitudinal and transverse directions. 7mN or less. The first nonwoven fabric 52 has an upper layer 15 and a lower layer 16, and the nonwoven fabric constituting the liquid-retaining sheet 11 of the panty liner 1 of the first embodiment has the same structure. The fiber structure of the upper layer 15 and the lower layer 16 is the same as the first embodiment. The upper layer 15 is formed by an upper fiber web of 70% by mass of cotton and pET3 0% by mass of weak hydrophilicity, and the lower layer 16 is formed by 60% by mass of rayon and 40% by mass of durable hydrophilic PET. The first non-woven fabric 5 2 is laminated with the upper layer of the upper layer of the above-mentioned lower layer of the web and imparts water spray-22- (20) M274925 2 0 ~ 60 g / m2. The total weight per unit area of the liquid-retaining sheet 5 1 composed of the first nonwoven fabric 52 and the second nonwoven fabric 53 is 4 5 to 1 10 g / m ° The panty liner 50 is provided to the skin side surface as shown in FIG. 6. The liquid of 3 is formed by the gradient of the hydrophilicity of the first nonwoven fabric 5 2 and the hydrophilicity of the second nonwoven fabric 5 3. Quickly attracted, the liquid 25 is held inside the second nonwoven fabric 5 3. Therefore, the liquid does not easily remain on the skin side surface 3 and does not give the skin a sticky feeling. Furthermore, in each of the above-mentioned embodiments, although the non-woven portion is formed by a water-jet weft-injection treatment, each non-woven fabric does not contain an adhesive 'and can be formed by interlacing fibers in a crosswise manner by needle punching.
