M269875 (1) 八、新型說明 【新型所屬之技術領域】 本創作是有關黏著於襯褲的股布部在穿著時,沒有不 舒適感而可以獲得和襯褲一體之接觸觸感的內褲襯片。 【先前技術】 內褲襯片是使用在吸收女性除了生理日以外的日子裏 的月經等膣分泌物之用。該內褲襯片是在黏貼於襯褲的股 布部的狀態下和襯褲同時穿著。 記載在以下的日本創作專利文獻i的內褲襯片是以表 面材覆蓋襯墊材的肌膚側表面的構造。上述襯墊材是以熱 黏合法黏結複合合成纖維彼此間織物單位面積重量4 0 g / m2 左右的不織布所形成。使用以熱黏合法黏結複合合成纖維 彼此間的不織布,可提高相對於使用時變形的恢復性。 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層 。上述不織布薄片TH以卡式形成混合人造絲纖維和聚醋纖 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,黏著纖維間的同時,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 -5- (2) (2)M269875 【新型內容】 〔創作所欲解決之課題〕 上述創作專利文獻1記載的內褲襯片是使用以熱黏合 法黏結纖維彼此間的不織布作爲構成襯墊材的不織布,專 利文獻2記載的內褲襯片則是使用黏合劑黏結纖維彼此間 作爲不織布薄片。壓縮力作用在上述任一的不織布時可發 揮彈性恢復力。 因此,將該等內褲襯片黏著在襯褲的股布部和襯褲同 時穿著時,穿著者受到襯褲的股布部以內褲襯片補強的觸 感,並且襯褲不能柔軟地追隨著身體的運動,以致在股間 部持續產生不舒適感的狀態。 此外,此種的內褲襯片在使用前的狀態是摺疊成2片 重疊或3片重疊所成的包裝。但是,構成上述內褲襯片的 不織布利用熱黏合法形成,或者以黏合劑黏結纖維彼此間 構成時,從包裝中取出展開內褲襯片時,在摺疊的位置上 仍存在壓縮的殘留而容易殘留凹陷部。另外,在摺疊線的 位置上也會因纖維的凝聚而呈現硬質化。將此內褲襯片放 置在股間部時,上述的部分對於膣口及其周圍更容易產生 異物感。 並且,專利文獻2記載的是含保持上述不織布薄片的 形狀可獲得彈性恢復性用的黏合劑。但是,直接抵接女性 膣周邊的不織布上含有黏合劑對於肌膚的刺激或肌膚安全 性的面而言並不理想。 -6 - (3) M269875 本創作是爲了解決上述習知的課題所硏創而成,提供 以薄型且和布製的襯褲同樣的軟質物,可經常和襯褲形成 一體變形’對於穿著時的股間部不會給予不舒適感的內褲 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’縱向長度尺寸較橫向寬度尺寸長的縱長形狀的內 褲襯片中,其特徵爲: 上述保液薄片是以1片以上的不織布所形成,含6 0 貞里/〇以上的纖維素絲纖維’上述不織布並非黏結纖維彼 此而是經緯交織所形成,在黏結上述保液薄片和上述內面 薄片的狀態下,縱向的懸臂法測定的硬挺度每20mm寬度 爲 40〜110mm 〇 本創作的內褲襯片是以至少1片的不織布所形成的保 液薄片和內面薄片所構成,形成可呈薄型的構造。上述保 液薄片由於含有60質量%以上的纖維素絲纖維,因此可以 上述保液薄片吸收膣分泌物加以保持。含纖維素絲纖維的 不織布在內部不含黏合劑,並非如熱黏合法黏結纖維彼此 之間。因此,內褲襯片整體可以形成軟質,在黏結襯褲的 股布部穿著時,內褲襯片可以發揮和襯褲的股布部的布同 等的軟質性而容易追隨襯褲的股布部的變形。因此,對於 股間部不會產生不舒適感,可獲得內褲襯片作爲襯褲的股 布部的一部份形成一體化的觸感。 M269875 (4) 並且,硬挺度在40mm以上,因此內褲襯片具有維持 製品形狀所必須的剛性,在黏結襯褲的股布部時,不會產 生內褲襯片必要以上的下垂,可以確實地黏結在股布部。 又本創作的內褲襯片厚度方向的壓縮恢復性爲 4 0〜5 5%° 厚度方向的壓縮恢復性在上述範圍時,在抵接膣口及 其週邊時不容易造成股間部的不舒適感。並且在使用前摺 疊內褲襯片形成包裝時,壓縮恢復性在上述範圍,開啓包 裝展開時,在摺疊線部分不容易殘留凹陷,並在摺疊線部 分也不容易凝聚纖維。 例如,本創作是以2片不織布彼此黏結構成上述保液 薄片’呈現在肌膚側表面的第1不織布和位於穿著側的第 2不織布形成不同的纖維的調和,上述第1不織布和第2 不織布同樣含有3 0質量%以上的纖維素絲纖維,並且在2 片不織布整體中可以構成含60質量%以上的纖維素絲纖維 〇 桌1不織布和第2不織布同樣含有纖維素絲纖維,藉 此可以將保液薄片的硬挺度和壓縮恢復性設定在上述範圍 。以第1不織布和第2不織布變化纖維素絲纖維的含有率 ’在保液薄片內可以形成厚度方向的親水度梯度,形成液 體迅速吸收的功能或確保液體保持容量的功能容易地發揮 〇 上述中,第1不織布和第2不織布同樣以織物單位面 積重量20〜70g/m2爲佳。並且2片不織布的總計織物單位 (5) M269875 面積重量在120g/m2以下爲佳。 在上述範圍中,可以構成薄型化且軟質的內褲襯片。 或者,本創作中,上述保液薄片是以丨片不織布所形 成’該不織布是以呈現在肌膚側表面的上層,和呈現在穿 衣側表面的下層形成不同纖維的調和,上述上層和上述下 層同樣含有3 0質量%以上的纖維素絲纖維,並且不織布整 體中可以含60質量%以上的纖維素絲纖維所構成。 該構成的內褲襯片的硬挺度和壓縮恢復性可以上述同 樣的範圍,並且在上層和下層藉著纖維素絲纖維調和率的 變化,形成親水度的梯度。 此時,構成上述保液薄片的上述1片不織布的織物單 位面積重量以25〜80g/m2爲佳。 本創作中,上述保液薄片和上述內面薄片重疊而彼此 黏結狀態下的厚度尺寸是以1 .2mm以下爲佳,尤其以 1 . 0 m m以下更佳。 並且,本創作的內褲襯片由於構成不織布的纖維彼此 不黏結而形成自由狀態,因此不容易殘留摺痕,在摺線的 部分不容易殘留凹陷或纖維的凝聚。因此,展開放置時在 膣口及其週邊不易產生不舒適感。 〔創作效果〕 本創作的內褲襯片容易追隨布製襯褲的股布部的變形 不致對股間部產生不舒適感’而可獲得和上述股布部形成 一體,即有如股布部一部份的接觸觸感。 -9- M269875 ⑹ 【實施方式】 第1圖是從肌膚側表面表示本創作第1實施形態的內 褲襯片1的上視圖,第2圖爲第1圖的Π - Π線剖視圖, 第3圖爲上述內褲襯片1的擴大剖視圖。 第1圖表示的內褲襯片1沿著縱向中心線0 y的方向 爲縱向,和縱向中心線〇y正交的方向爲橫向。內褲襯片 1是形成縱向尺寸較橫向尺寸長的縱長形狀。 內褲襯片1的前緣部1 a及後緣部1 b是朝著前方和後 方呈凸狀的曲線形狀,右側緣部1 c和左側緣部1 d是朝橫 向呈凹狀的曲線形狀。上述前緣部1 a和後緣部1 b及左右 兩側緣部1 c、1 d的內側形成有壓花部2。該壓花部2是從 肌膚側表面加熱壓縮而形成凹狀,該實施形態中,黏結藉 上述壓花部2構成保液薄片的不織布,同時藉上述壓花部 2表現出預定圖案的模樣。 如第2圖表示,該內褲襯片1的本體部1〇是以2片 不織布所形成的保液薄片1 1,和重疊在該保液薄片1 1上 的內面薄片12及形成在內面薄片11表面的感壓黏著劑層 13所構成。並且,在上述本體10的內面重疊黏合有剝離 型薄片20,保護著上述感壓黏著劑層1 3。上述本體部;! 〇 形成有保液薄片1 1的面爲肌膚側表面3,形成內面1 2的 面爲穿衣側表面4。 上述保液薄片1 1是以第1不織布1 5和第2不織布1 6 所構成,第1不織布1 5形成在肌膚側表面3,第2不織布 -10- (7) M269875 1 6是位在穿衣側。第1不織布1 5和第2不織布1 6是藉熱 融型黏合劑黏合。熱融型黏合劑的塗敷量設定在不會妨礙 從第1不織布1 5到第2不織布1 6之間液體的通過,並且 不會妨礙內褲襯片30整體的軟質感的5〜30g/m2的範圍內 。黏合第2不織布1 6和內面薄片1 2之間的熱融型黏合劑 具有相同的塗敷量。 內褲襯片30是在保液薄片11重疊內面薄片12而黏 結的狀態下,厚度爲1.2mm以下,以1.0mm以下的薄構 造爲佳。在黏結上述保液薄片1 1和內面薄片1 2之物中, 藉隨後說明的懸臂法測定的硬挺度每20mm寬度爲 4 0〜1 1 0 m m的範圍,形成極爲軟質,可獲得如襯褲的股布 部一部份的觸感,不易造成股間部的不舒適感。但是硬挺 度由於在40mm以上,必須要具備維持形狀的剛性,在黏 結襯褲時不會因不注意而產生不必要的變形彎曲。 又’隨後說明朝著厚度方向壓縮時的壓縮恢復力爲 4 0〜5 5%。因此,相對於厚度方向的壓縮力的恢復阻力不會 造成過大,在安置於股間部時不易產生不舒適感。並且, 由於壓縮恢復性在40%以上,因此在構成保液薄片1 1的 不織布內部可經常性形成纖維間的空隙,藉著纖維間的間 隙的毛細管作用發揮液體的吸引能力。並可確保上述空隙 內的保液容量,充分發揮吸收如膣分泌物的少量排泄液體 而加以保持的功能。 由於上述硬挺度和壓縮恢復性設定在上述數値範圍, 因此保液薄片1 1其整體含有6 0質量%以上的纖維素絲纖 -11 - (8) M269875 維。以含有纖維素絲纖維65質量%以上,更以含有7〇質 量%以上爲佳。上述第1不織布1 5和第2不織布1 6的纖 維調和比例雖然不问’但是弟1不織布1 5和第2不織布 1 6中的纖維素絲纖維的調和比例較少側的不織布中,同樣 地上述纖維素絲纖維含有至少3 0質量%。 上述第1不織布1 5和第2不織布1 6雖然任意纖維彼 此間經緯交織保持著薄片形狀,但是不織布內不含黏合劑 (binder ),不會因該黏合劑而黏著纖維彼此間。上述纖 維的經緯交織是藉噴水投緯法或針座環法等進行。 本說明書中的「不會黏著纖維彼此間」是表示如上述 藉黏合劑黏著纖維,或以熱熔融合成樹脂纖維的表面不致 使纖維彼此間黏附。 又’以濕式製造第1不織布1 5和第2不織布1 6時, 利用其乾燥步驟的加熱,藉其表面的OH基產生纖維素絲 纖維的氫鍵現象。上述「不會黏著纖維彼此間」是表示未 產生上述氫鍵爲止之前。 但是’形成軟質的內褲襯片更以藉著調整上述乾燥步 驟的加熱溫度’或者調整使纖維間隔擴開用的空氣壓等, 在第1不織布15和第2不織布16內不產生具有OH的纖 維的氫鍵爲佳。 上述第1不織布1 5和第2不織布1 6分別的各個織物 單位面積重量調整在20〜70g/m2的範圍,以調整第1不織 布1 5和第2不織布1 6的總計織物單位面積重量形成 120g/m以下爲佳,更以1〇〇g/m2以下爲佳。 -12- (9) M269875 上述織物單位面積重量的範圍所形成的第1不織布1 5 和第2不織布1 6 ’整體含有6 0質量%以上的軟質纖維素 絲纖維,並以含有65質量%以上的纖維素絲纖維爲佳’以 含有70質量%以上更佳,在各不織布內不黏著纖維而較具 自由度,因此可以將硬挺度及壓縮恢復性設定在上述數値 範圍內。 其中,上述纖維素絲纖維可例示如棉、漿粕、麻、再 生纖維的人造絲、銅氨纖維、虎木棉(P〇lyn〇sic ray〇n) 。並且,上述保液薄片1 1除了上述纖維素絲纖維之外, 也可以含半合成纖維的醋酯纖維、合成樹脂的聚醯胺系( 例如尼龍)、聚乙烯醇系(例如維尼綸)、PP (聚丙烯) 、PE (聚乙烯)、PET (聚對苯二甲酸乙二酯)等各纖維 〇 第1不織布1 5和第2不織布1 6是以噴水投緯法所形 成的水針不織布(spun lace )時,噴水投緯1次的處理能 量爲0.09〜0.5 ( 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 ·63χ噴射壓力( kgf/cm2 ) X噴射流量(m3/min) } +處理速度(m/min) 求得。 噴水投緯噴嘴的開口直徑爲70〜120μιη,對CD的排列 節距爲0.3〜2.0mm。 噴水投緯的處理能量設定在上述範圍,在第1不織布 1 5和第2不織布1 6內纖維彼此間不會造成過剩地經緯交 織,纖維可以比較具有自由度,在重疊保液薄片1 1和內 -13- (10) (10)M269875 面薄片1 2的織物中,縱向的硬挺度和壓縮時的壓縮恢復 性可以形成在上述數値範圍內。 第1的實施形態中,如擴大第3圖所示,上述第1不 織布1 5爲具有上層1 7和下層1 8的2層水針不織布。 上述第1不織布15在形成下層18的下層纖維網上重 疊形成上層1 7的上層纖維網,如上述相對於層疊後的纖 維網從上層纖維網側賦予噴水投緯,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。 上層1 7含有纖維素絲纖維和疏水性或者弱親水性合 成樹脂纖維,下層含有纖維素絲纖維和耐久親水性合成樹 脂纖維。 本說明書的疏水性纖維是意味著法定吸濕率爲〇 %, 弱親水性纖維是意味著上述法定吸濕率小於3 %且不等於 〇%。並且親水性纖維是意味著以法定吸濕率3 %以上並以 5 %以上爲佳。法定吸濕率是相對於2 0 °C放置在相對溼度 6 5 °/。的周圍環境空氣內時的纖維質量而吸附在該纖維上的 水分質量的比例(含水率)。 纖維素絲纖維是法定吸濕率爲5 %以上的親水性。又 P E T等的合成樹脂纖維是在表面塗敷表面活性劑等的親水 化劑,並在樹脂內混練親水化劑以型成親水性。並在表面 形成具有凹凸的不同剖面形狀使合成樹脂纖維形成親水性 〇 上述第1不織布1 5在上層1 7含有疏水性或弱親水性 -14- (11) (11)M269875 的合成樹脂纖維,下層1 8含有纖維素絲纖維和親水性合 成樹脂纖維,因此下層1 8具有高於上層1 7的親水度,可 以將液體迅速地從上層1 7吸引到下層1 8。又,第1不織 布1 5在上層1 7和下層1 8含有合成樹脂纖維,因此肌膚 側表面3的表面強度高,在含液體厚的濕潤狀態下,不容 易因外力而發生破損。爲了保持該表面強度在第1不織布 15含有20質量%以上的合成樹脂纖維爲佳。 第1實施形態中,上述第2不織布1 6僅以纖維素絲 纖維形成。第2不織布16是以纖維素絲纖維爲主體,因 此較上述下層1 8更具有高的親水度,從第!不織布1 5的 上層1 7吸至下層1 8的液體更形成朝著第2不織布1 6迅 速地吸入保持。但是,也可以在第2不織布1 6整體的剛 性不高的範圍內含親水性的合成樹脂纖維。 上述內面薄片12是以聚乙烧形成,或者水針不織布 (S )和熔融斷不織布(μ )是以S / M / S的順序層疊黏結 的複合不織布等所形成。並且內面薄片1 2以使用通氣性 物爲佳。內面薄片1 2是使用內褲襯片1整體的硬挺度形 成在上述數値範圍內的軟質物,以使用上述聚乙烯薄膜爲 佳。該薄膜的織物單位面積重量爲1 〇〜40 g/m2左右。更以 使用伸縮性薄膜作爲上述內面薄片1 2爲佳。該伸縮性薄 膜爲LDPE (低密度聚乙烯)和α烯烴系樹脂的2層同時 擠製所形成。使用伸縮性薄膜時,將內褲襯片1黏著在襯 褲的股布部內面時,容易追隨襯褲股布部的伸縮而變形。 上述第2不織布16和內面薄片12是藉熱融型黏著劑 -15- (12) (12)M269875 的塗敷量5〜30g/m2爲佳。 上述感壓黏著劑層13是在內面薄片12的表面縱向平 行延伸形成條紋狀。感壓黏著劑層1 3是以橡膠系感壓型 熱融黏著劑所形成。該實施形態中,1個上述感壓黏著劑 層13的寬度尺寸爲4mm,感壓黏著劑層13是平行設置 2 0條。感壓黏著劑的總計織物單位面積重量爲3 3 g/m2。 但是感壓黏著劑層1 3的形成圖案不僅限於上述樣態,例 如也可以橫向延伸的條紋圖案等,也可以塗敷內面薄片1 2 的整面。但是,內面薄片1 2爲通氣性時,以不損及通氣 性的如條紋的圖案化爲佳。 上述玻璃型薄片2 0是在玻璃紙等的紙材表面使用塗 敷有矽等的剝離型處理劑等。 第4圖是表示本創作第2實施形態的內褲襯片3 0的 剖視圖,第5圖爲其部分擴大的擴大剖視圖。 第2實施形態的內褲襯片3 0的形狀是和第1圖表示 的第1實施形態相同,內面薄片1 2、感壓黏著劑層1 3及 剝離型薄片2 0等是使用和上述第1實施形態相同之物。 如第4圖和第5圖表示,內褲襯片30的本體部40是 以1片不織布所形成的保液薄片3 1、內面薄片1 2及感壓 黏著劑層1 3所構成。 構成上述保液薄片3 1的丨片不織布,織物單位面積 重量在25〜80 g/m2的範圍。該保液薄片31爲2層水針不 織布,上層3 2和下層3 3是以不同的纖維調合。2層水針 不織布的製造方法是和上述第1實施形態的第1不織布】5 -16- (13) (13)M269875 相同。 構成保液薄片3 1的1片不織布含有60質量%以上的 纖維素絲纖維。又以含有65質量%以上的上述纖維素絲纖 維爲佳,並以70質量%以上更佳。但是,上層32含有上 層32的質量的20 %以上的合成樹脂纖維,提高肌膚側表 面3的表面強度。 上述下層3 3僅以纖維素絲纖維形成。或者下層3 3也 可以上述纖維素絲纖維和耐久親水性的合成樹脂纖維形成 。下層3 3含有合成樹脂纖維,下層3 3中在纖維間可以保 持空隙,可提高液體的保持容量。 上層3 2含有疏水性合成樹脂纖維,藉以使下層3 3較 上層3 2的親水性高,從肌膚側表面3賦予保液薄片3 1的 液體可藉著下層3 3的親水力迅速地透過上層3 2而吸引到 下層33,形成在下層33保持著液體。並且,上層32含有 疏水性合成樹脂纖維,藉以使吸引保持在下層3 3的液體 不易回流到保持薄片3 1的肌膚側表面。 內褲襯片30是在保液薄片31上重疊內面薄片12的 狀態形成厚度1 .2mm以下,以1 .0mm以下的薄型構造爲 佳。構成上述保液薄片3 1的不織布不含黏合劑,並且纖 維彼此間未熔融黏著。內面薄片1 2重疊在保液薄片3 1的 狀態下藉懸臂法測定縱向硬挺度在每 20mm寬度爲 4〇〜11 0mm的範圍,朝厚度方向壓縮時的壓縮恢復性爲 4 0〜55〇/〇° 上述兩實施形態的內褲襯片1、30,其本體部10、40 -17- (14) (14)M269875 是以具有液體吸收能力和保持能力的不織布所形成的保液 薄片11、31和內面薄片12及感壓黏著劑13所構成。因 此,可以構成薄型而構成軟質的整體。 硬挺度在上述數値範圍內時,將內褲襯片1、3 0經由 感壓黏著劑層1 3黏著在襯褲的股部布內面的狀態下’追 隨襯褲的變形可以使內褲襯片變形,穿著人不易受到股間 部的不舒適感。上述硬挺度時的內褲襯片1、3 0在穿著的 狀態下,可以獲得和襯褲相同的觸感。並且’由於硬挺度 在4 0 m m以上,因此容易保持內褲襯片1、3 0的形狀,例 如將剝離型薄片2 0剝除,以手指保持中央部分而黏著在 襯褲的股部布時,不致使前緣部1 a和後緣部1 b造成8 0 度以上大的撓曲而下垂。因此,可以防止經感壓黏著劑層 1 3導致內面薄片1 2彼此間貼合等的問題,在襯褲的股部 布,可以將內褲襯片1、3 0確實黏著在襯褲的股部部內面 〇 壓縮恢復性在上述數値範圍內,從肌膚側表面局部性 按壓保液薄片1 1、3 1時,使其周邊彈性恢復不容易在其 按壓部分產生凹陷等現象。因此,同時在以指甲前端局部 性按壓其整體的形狀也不會產生大的變化。 如第6圖表示,內褲襯片1、30在黏著上述剝離型薄 片2 0的狀態下,更將個別包裝用的包裝紙重疊在剝離型 薄片20上,整體呈3層重疊狀態,或者摺疊成2層重疊 狀態包裝。該包裝狀態長期間持續時在摺線的部分上,對 保液薄片1 1、3 1持續的局部性壓縮力的作用。但是,壓 -18- (15) M269875 縮恢復性在上述數値的範圍時,包裝開_ 、3 0時,摺線的部分不易殘留大的凹陷, 維呈比較自由的狀態,因此具有摺線的β 纖維集中而凝聚等現象。 如上述,使用時可以保持著肌膚側表 不易造成膣口或其周邊的不舒適感。 再者,本創作不僅限於上述實施的型 液薄片1

Description of the new type [Technical field to which the new type belongs] This creation is about a panty liner that can be integrated with the underpants without any uncomfortable feeling when worn by the part of the cloth attached to the underpants. [Prior art] The panty liner is used to absorb menstrual secretions such as menstruation on days other than the physiological day of women. This panty liner is worn simultaneously with the panty in a state of being adhered to the thigh portion of the panty. The panty liner described in the following Japanese Creative Patent Document i has a structure in which the skin-side surface of the cushion material is covered with a surface material. The above-mentioned cushion material is formed of a non-woven fabric having a weight per unit area of about 40 g / m2 between the composite synthetic fibers bonded by thermal bonding. The use of non-woven fabrics that bond the composite synthetic fibers with each other by heat bonding can improve the recovery from deformation during use. The panty liner described in the following Japanese Creative Patent Document 2 has a single non-woven sheet positioned on the skin side and has a liquid-impermeable barrier on the wearing side. The non-woven fabric sheet TH is formed into a fiber web in which rayon fibers and polyester fibers are mixed in a card type, 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 applied to the above-mentioned nonwoven fabric sheet, and the shape of the recessed portion is maintained while adhering between the fibers, and the elastic recovery function during compression can be improved. [Creation Patent Document 1] Japanese Patent Publication No. 8-2 4 2 8 9 [Creation Patent Document 2] Japanese Patent Publication No. 7 _ 1 3 8 8 6 5-5- (2) (2) M269875 [New Content ] [Problems to be Solved by the Creation] The underpants lining described in the above-mentioned creation patent document 1 is a non-woven fabric made of a non-woven fabric using heat-bonded fibers to bond with each other, and the underpants lining described in patent document 2 is used. The binder binds the fibers with each other as a non-woven sheet. The compressive force exerts elastic restoring force when it is applied to any of the non-woven fabrics described above. Therefore, when the panty lining is adhered to the panty portion of the panty and the panty is worn at the same time, the wearer is touched by the panty portion of the panty with the panty lining, and the panty cannot follow the movement of the body softly, so that Discomfort continues to occur in the intertrochanteric area. In addition, this kind of panty liner is folded into a package formed by overlapping two sheets or three sheets before use. However, when the non-woven fabric constituting the underpants is formed by heat bonding, or when the adhesive is used to bind fibers to each other, when the unfolded underpants are taken out from the package, there is still a compression residue at the folded position and it is easy to dent unit. In addition, the position of the folding line is also stiffened by the aggregation of fibers. When this panty liner is placed in the intertrochanter part, the aforementioned part is more likely to have a foreign body sensation in the mouth and the periphery. Further, Patent Document 2 describes an adhesive containing an elastic recovery property by maintaining the shape of the nonwoven fabric sheet. However, non-woven fabrics that are in direct contact with women's hairpin are not ideal for skin irritation or skin safety. -6-(3) M269875 This creation was created to solve the above-mentioned conventional problems. It provides a thin and soft material similar to cloth panties, which can often be deformed integrally with the panties. 'For the interfemoral part when worn The purpose of the panty liner is not to give discomfort. [Means for solving the problem] The present invention has a liquid-retaining sheet and an inner surface sheet that is superimposed on the wearing side of the liquid-retaining sheet. The panty liner having a longitudinal length longer than a lateral width is characterized by: The liquid-retaining sheet is formed by one or more non-woven fabrics, and contains cellulose silk fibers of 60% or more. The non-woven fabric is formed by interweaving warp and weft instead of bonding fibers. The liquid-retentive sheet and the inner surface are bonded together. In the state of the sheet, the stiffness measured by the vertical cantilever method is 40 to 110 mm per 20 mm width. The panty liner of this creation is composed of a liquid-retaining sheet and an inner sheet formed of at least one non-woven fabric. Thin structure. Since the liquid-retaining sheet contains 60% by mass or more of cellulose filament fibers, the liquid-retaining sheet can be absorbed and held by the radon secretion. Non-woven fabrics containing cellulose silk fibers do not contain binders inside, and do not bond fibers to each other like heat bonds. Therefore, the entire panty lining can be made soft. When the panty portion of the panty is bonded, the panty lining can exhibit the same softness as the cloth of the panty portion of the panty and easily follow the deformation of the panty portion of the panty. Therefore, an uncomfortable feeling is not generated in the intertrochanter portion, and an integrated tactile sensation can be obtained as a part of the panty portion of the panty liner of the underpants. M269875 (4) In addition, the stiffness is 40mm or more, so the panty lining has the rigidity necessary to maintain the shape of the product. When bonding the panty portion of the panty, the panty lining does not sag more than necessary, and can be reliably bonded to Department of cloth. The compression recovery of the panty liner in the thickness direction of this creation is 40 ~ 5 5% °. When the compression recovery of the thickness direction is within the above range, it is not easy to cause discomfort in the intertrochanter part when it comes into contact with the mouth and the periphery. . In addition, when the panty liner is folded before use to form a package, the compression recovery is within the above range. When the package is opened and unfolded, the dent is not easy to remain in the fold line portion, and the fiber is not easy to aggregate in the fold line portion. For example, in this creation, two non-woven fabrics are bonded to each other to form the liquid-retaining sheet. The first non-woven fabric on the skin side and the second non-woven fabric on the wearing side form different fibers. The first non-woven fabric and the second non-woven fabric are the same. Contains more than 30% by mass of cellulose silk fibers, and can form 60% by mass or more of cellulose filament fibers in the entire two sheets of nonwoven fabrics. Table 1 nonwoven fabric and second nonwoven fabric also contain cellulose filament fibers. The stiffness and compression recovery of the liquid-retaining sheet are set within the above-mentioned ranges. Changing the content of cellulose silk fibers with the first nonwoven fabric and the second nonwoven fabric 'can form a thickness-wise hydrophilicity gradient in the liquid-retaining sheet, and the function of quickly absorbing liquid or ensuring the capacity of holding liquid can be easily exerted. The first non-woven fabric and the second non-woven fabric also preferably have a fabric basis weight of 20 to 70 g / m2. And the total fabric unit of 2 pieces of non-woven fabric (5) M269875 It is better that the area weight is less than 120g / m2. Within the above range, a thin and soft panty liner can be formed. Alternatively, in this creation, the liquid-retaining sheet is formed by a sheet of non-woven fabric. The non-woven fabric is a blend of different fibers formed on the upper surface of the skin side surface and the lower layer on the dressing side surface. Similarly, it contains 30% by mass or more of cellulose silk fibers, and the entire non-woven fabric may contain 60% by mass or more of cellulose silk fibers. The stiffness and compression recovery of the panty liner of this structure can be in the same range as described above, and a gradient of hydrophilicity is formed in the upper layer and the lower layer by the change of the cellulose silk fiber blending ratio. At this time, the fabric unit area weight of the one nonwoven fabric constituting the liquid-retaining sheet is preferably 25 to 80 g / m2. In this creation, the thickness dimension of the liquid-retaining sheet and the inner-surface sheet overlapping with each other is preferably 1.2 mm or less, and more preferably 1.0 mm or less. In addition, since the underwear linings created in the present invention are in a free state because the fibers constituting the non-woven fabric do not stick to each other, creases are not easily left, and dents or aggregation of fibers are not easy to remain in the part of the fold line. Therefore, it is not easy to cause discomfort in the mouth and the surrounding area when it is deployed. [Creation effect] The panty liner of this creation is easy to follow the deformation of the cloth portion of the cloth panty without causing an uncomfortable feeling to the inter-strand portion, and can be integrated with the above-mentioned cloth portion, that is, the contact of a portion of the cloth portion Touch. -9- M269875 实施 [Embodiment] FIG. 1 is a top view showing the panty liner 1 of the first embodiment of the present invention from the side surface of the skin, and FIG. 2 is a cross-sectional view taken along line Π-Π of FIG. 1 and FIG. 3 This is an enlarged cross-sectional view of the above-mentioned underwear liner 1. The direction of the panty liner 1 shown in FIG. 1 along the longitudinal center line 0 y is longitudinal, and the direction orthogonal to the longitudinal center line 0 y is lateral. The panty liner 1 is formed in a longitudinal shape having a longitudinal dimension longer than a lateral dimension. The front edge portion 1a and the rear edge portion 1b of the panty liner 1 are curved shapes that are convex toward the front and rear, and the right edge portion 1c and the left edge portion 1d are curved shapes that are concave toward 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, 1 d. The embossed portion 2 is heated and compressed from the skin-side surface to form a concave shape. In this embodiment, the non-woven fabric formed by the embossed portion 2 to form a liquid-retaining sheet, and the embossed portion 2 exhibits a predetermined pattern. As shown in FIG. 2, the main body portion 10 of the panty liner 1 is a liquid-retaining sheet 11 formed by two non-woven fabrics, an inner-surface sheet 12 superimposed on the liquid-retaining sheet 11, and an inner surface. The pressure-sensitive adhesive layer 13 on the surface of the sheet 11 is formed. A peeling sheet 20 is laminated on the inner surface of the main body 10 to protect the pressure-sensitive adhesive layer 13. The above main body portion;! 〇 The surface on which the liquid-retaining sheet 11 is formed is the skin-side surface 3, and the surface on which the inner surface 12 is formed is the dressing-side surface 4. The liquid-retaining sheet 11 is composed of a first non-woven fabric 15 and a second non-woven fabric 16. The first non-woven fabric 15 is formed on the skin-side surface 3, and the second non-woven fabric-10- (7) M269875 1 6 is worn. Clothing side. The first non-woven fabric 15 and the second non-woven fabric 16 are bonded by a heat-melting adhesive. The application amount of the hot-melt adhesive is set to 5 to 30 g / m2 that does not prevent the passage of liquid from the first nonwoven fabric 15 to the second nonwoven fabric 16 and does not hinder the soft texture of the panty liner 30 as a whole. In the range. The same amount of hot-melt adhesive was used to bond the second nonwoven fabric 16 and the inner sheet 12 to each other. The underpants lining sheet 30 is preferably a thin structure having a thickness of 1.2 mm or less and a thickness of 1.0 mm or less in a state where the liquid-retaining sheet 11 is superposed on the inner surface sheet 12 and bonded. When the liquid-retaining sheet 11 and the inner sheet 12 are bonded, the stiffness measured by the cantilever method described later is in the range of 40 to 110 mm per 20 mm width, and is extremely soft. The tactile sensation of a part of the cloth part is not easy to cause the discomfort of the interfemoral part. However, since the stiffness is more than 40 mm, it is necessary to have rigidity to maintain the shape, and there is no need to cause unnecessary deformation and bending when bonding the underpants. It will be described later that the compression restoring force when compressed in the thickness direction is 40 to 55%. Therefore, the recovery resistance against the compressive force in the thickness direction is not excessively large, and it is difficult to cause uncomfortable feeling when it is placed in the interfemoral part. In addition, since the compression recovery is 40% or more, voids between the fibers can be frequently formed inside the nonwoven fabric constituting the liquid-retaining sheet 1 1, and the liquid suction ability is exerted by the capillary action of the gaps between the fibers. It can also ensure the liquid-retaining capacity in the above-mentioned gaps, and fully exert the function of absorbing a small amount of excretion fluid such as the salamander secretion and maintaining it. Since the stiffness and compression recoverability are set within the above range, the liquid-retaining sheet 11 as a whole contains 60% by mass or more of cellulose silk fibers -11-(8) M269875. It is preferably 65% by mass or more, and more preferably 70% by mass or more. Although the fiber blending ratio of the first nonwoven fabric 15 and the second nonwoven fabric 16 described above is not required, the blending ratio of the cellulose silk fibers in the first nonwoven fabric 15 and the second nonwoven fabric 16 is the same in the nonwoven fabric of the same side. The said cellulose silk fiber contains at least 30 mass%. Although the first nonwoven fabric 15 and the second nonwoven fabric 16 mentioned above are woven with each other in warp and weft to maintain a sheet shape, the nonwoven fabric does not contain a binder, and the fibers do not adhere to each other due to the binder. The warp and weft interweaving of the fibers is performed by a water jet weft insertion method or a needle ring method. In the present specification, "the fibers do not adhere to each other" means that the fibers are adhered by a binder as described above, or that the surfaces of the synthetic resin fibers are not melted by thermal fusion. Also, when the first nonwoven fabric 15 and the second nonwoven fabric 16 are manufactured by wet method, the hydrogen bonding phenomenon of the cellulose silk fiber is generated by the OH group on the surface by heating in the drying step. The above-mentioned "non-adhesive fibers between each other" means before the above-mentioned hydrogen bond is not generated. However, 'the soft underpants are formed by adjusting the heating temperature in the above-mentioned drying step' or adjusting the air pressure for expanding the fiber space, etc., the fibers having OH are not generated in the first nonwoven fabric 15 and the second nonwoven fabric 16 Hydrogen bonds are preferred. The weight of each fabric of the first nonwoven fabric 15 and the second nonwoven fabric 16 is adjusted in the range of 20 to 70 g / m2 to adjust the total fabric basis weight of the first nonwoven fabric 15 and the second nonwoven fabric 16 to 120 g. It is more preferably less than 100 m / m, more preferably less than 100 g / m2. -12- (9) M269875 The first non-woven fabric 15 and the second non-woven fabric 16 formed by the range of weight per unit area of the fabric described above contain 60% by mass or more of soft cellulose silk fibers and 65% by mass or more Cellulose silk fibers are preferred to contain 70% by mass or more, and there is no degree of freedom in non-woven fabrics due to non-adhesive fibers. Therefore, stiffness and compression recovery can be set within the aforementioned ranges. Among them, the cellulose silk fiber may be exemplified by cotton, pulp, hemp, rayon of regenerated fiber, copper ammonia fiber, and tiger kapok (Polynosic rayon). The liquid-retaining sheet 11 may include, in addition to the cellulose silk fibers, acetate fibers of semi-synthetic fibers, polyamide-based resins (such as nylon), polyvinyl alcohols (such as vinylon), and synthetic resins. Fibers such as PP (polypropylene), PE (polyethylene), and PET (polyethylene terephthalate). The first non-woven fabric 15 and the second non-woven fabric 16 are water-jet nonwoven fabrics formed by a water jet weft insertion method. In the case of (spun lace), the processing energy for one shot of weft injection is 0.09 to 0.5 (kw / m2), and the number of processing times is preferably 1 to 8 times. The above processing energy (kw / m2) is obtained by {1 · 63χ injection pressure (kgf / cm2) X injection flow rate (m3 / min)} + processing speed (m / min). The opening diameter of the water injection weft injection nozzle is 70 to 120 μm, and the arrangement pitch to the CD is 0.3 to 2.0 mm. The processing energy of water injection and weft insertion is set in the above-mentioned range. In the first nonwoven fabric 15 and the second nonwoven fabric 16, the fibers will not cause excessive warp and weft interweaving with each other. The fibers can have a relatively high degree of freedom. Uri-13- (10) (10) M269875 The surface of the sheet 12 has a stiffness in the longitudinal direction and a compression recovery property during compression that can be formed within the above range. In the first embodiment, as shown in the enlarged third figure, the first nonwoven fabric 15 is a two-layer water-jet nonwoven fabric having an upper layer 17 and a lower layer 18. The first non-woven fabric 15 is superposed on the lower fiber web forming the lower layer 18 to form the upper fiber web of the upper layer 17 as described above. Water jetting is performed from the upper fiber web side to the laminated fiber web, so that the fibers of the upper fiber web are mutually Between the fibers of the lower layer of the fiber web, the fibers of the upper layer of the fiber web and the fibers of the lower layer of the fiber web are interwoven with each other to form a piece of non-woven fabric. The upper layer 17 contains cellulose silk fibers and hydrophobic or weakly hydrophilic synthetic resin fibers, and the lower layer contains cellulose silk fibers and durable hydrophilic synthetic resin fibers. The hydrophobic fiber in this specification means that the legal moisture absorption rate is 0%, and the weakly hydrophilic fiber means that the legal moisture absorption rate is less than 3% and not equal to 0%. The hydrophilic fiber means that the legal moisture absorption rate is preferably 3% or more and 5% or more. The legal hygroscopicity is relative to 20 ° C at 5 ° / relative humidity. The proportion of water mass (water content) absorbed by the fiber when it is in the ambient air. Cellulose silk fibers are hydrophilic with a legal moisture absorption rate of 5% or more. Also, synthetic resin fibers such as P E T are coated with a hydrophilizing agent such as a surfactant, and the hydrophilizing agent is mixed in the resin to form a hydrophilic property. Different surface shapes with irregularities are formed on the surface to make the synthetic resin fibers hydrophilic. The first non-woven fabric 1 5 contains hydrophobic or weakly hydrophilic synthetic resin fibers in the upper layer 17-14- (11) (11) M269875, The lower layer 18 contains cellulose filament fibers and hydrophilic synthetic resin fibers, so the lower layer 18 has a higher degree of hydrophilicity than the upper layer 17 and can quickly attract liquid from the upper layer 17 to the lower layer 18. In addition, since the first nonwoven fabric 15 contains synthetic resin fibers in the upper layer 17 and the lower layer 18, the surface strength of the skin side surface 3 is high, and it is difficult to be damaged by external forces in a wet state containing liquid. In order to maintain this surface strength, the first nonwoven fabric 15 preferably contains 20% by mass or more of synthetic resin fibers. In the first embodiment, the second nonwoven fabric 16 is formed only of cellulose filament fibers. The second non-woven fabric 16 is mainly composed of cellulose silk fibers, and therefore has higher hydrophilicity than the lower layer 18 described above. The liquid sucked from the upper layer 17 of the non-woven fabric 15 to the lower layer 18 is more quickly sucked and held toward the second non-woven fabric 16. However, a hydrophilic synthetic resin fiber may be contained in a range where the rigidity of the entire second nonwoven fabric 16 is not high. The inner sheet 12 is formed of polyethylene, or a composite nonwoven fabric such as a water-jet nonwoven fabric (S) and a melt-cut nonwoven fabric (µ) laminated and bonded in the order of S / M / S. In addition, the inner sheet 12 is preferably made of a breathable material. The inner sheet 12 is a soft material which is formed within the above range using the overall stiffness of the panty liner 1. The polyethylene film is preferably used. The fabric has a basis weight of about 10 to 40 g / m2. It is more preferable to use a stretchable film as the inner surface sheet 12. This stretchable film is formed by simultaneous extrusion of two layers of LDPE (low density polyethylene) and an alpha olefin resin. When a stretchable film is used, when the panty backing sheet 1 is adhered to the inner surface of the panty portion of the panty, it is easy to deform following the expansion and contraction of the panty portion of the panty. The second non-woven fabric 16 and the inner surface sheet 12 are made of a hot-melt adhesive -15- (12) (12) M269875. The application amount is preferably 5 to 30 g / m2. The pressure-sensitive adhesive layer 13 is formed in a stripe shape by longitudinally extending in parallel with the surface of the inner surface sheet 12. The pressure-sensitive adhesive layer 13 is formed of a rubber-based pressure-sensitive hot-melt adhesive. In this embodiment, the width dimension of one of the pressure-sensitive adhesive layers 13 is 4 mm, and 20 pressure-sensitive adhesive layers 13 are arranged in parallel. The total fabric basis weight of the pressure-sensitive adhesive was 33 g / m2. However, the formation pattern of the pressure-sensitive adhesive layer 13 is not limited to the above. For example, a stripe pattern extending laterally may be applied, and the entire surface of the inner surface sheet 1 2 may be coated. However, when the inner surface sheet 12 is air-permeable, a pattern such as a stripe that does not impair air permeability is preferable. The glass type sheet 20 is a surface of a paper material such as cellophane, and a release type treatment agent coated with silicon or the like is used. Fig. 4 is a cross-sectional view showing the panty liner 30 of the second embodiment of the present invention, and Fig. 5 is an enlarged cross-sectional view showing a part thereof enlarged. The shape of the panty liner 3 0 of the second embodiment is the same as that of the first embodiment shown in FIG. 1. The inner sheet 1 2, the pressure-sensitive adhesive layer 13, and the release sheet 20 are used in the same manner as the first embodiment. 1 The same embodiment. As shown in Figs. 4 and 5, the main body portion 40 of the panty liner 30 is composed of a liquid-retaining sheet 31, an inner sheet 12, and a pressure-sensitive adhesive layer 13 formed of a single nonwoven fabric. The nonwoven fabric constituting the liquid-retaining sheet 31 described above has a basis weight of 25 to 80 g / m2. The liquid-retaining sheet 31 is a two-layer water-jet needle-woven fabric, and the upper layer 32 and the lower layer 33 are blended with different fibers. The manufacturing method of the two-layer water needle nonwoven fabric is the same as that of the first nonwoven fabric according to the first embodiment] 5 -16- (13) (13) M269875. One nonwoven fabric constituting the liquid-retaining sheet 31 contains 60% by mass or more of cellulose filament fibers. It is more preferable that the cellulose silk fiber contains 65% by mass or more, and more preferably 70% by mass or more. However, the upper layer 32 contains 20% or more of synthetic resin fibers based on the mass of the upper layer 32, and increases the surface strength of the skin-side surface 3. The lower layer 33 is formed only of cellulose silk fibers. Alternatively, the lower layer 3 3 may be formed of the cellulose silk fibers and durable hydrophilic synthetic resin fibers. The lower layer 33 contains synthetic resin fibers. In the lower layer 33, voids can be maintained between the fibers, and the holding capacity of the liquid can be increased. The upper layer 3 2 contains hydrophobic synthetic resin fibers, so that the lower layer 3 3 is more hydrophilic than the upper layer 3 2. The liquid imparted to the liquid-retaining sheet 31 from the skin-side surface 3 can quickly penetrate the upper layer by the hydrophilic force of the lower layer 3 3. 3 2 is attracted to the lower layer 33, and the liquid formed in the lower layer 33 is held. In addition, the upper layer 32 contains hydrophobic synthetic resin fibers so that the liquid sucked and held in the lower layer 3 3 cannot easily flow back to the skin-side surface of the holding sheet 31. The panty liner 30 preferably has a thickness of 1.2 mm or less and a thin structure of 1.0 mm or less in a state in which the inner sheet 12 is superposed on the liquid holding sheet 31. The nonwoven fabric constituting the liquid-retaining sheet 31 does not contain an adhesive, and the fibers are not melt-adhered to each other. The cantilever method was used to measure the longitudinal stiffness of the inner sheet 12 and the liquid-retaining sheet 3 1 in a range of 40 to 110 mm per 20 mm width, and the compression recovery when compressed in the thickness direction was 40 to 55. / 〇 ° The underpants linings 1 and 30 of the two embodiments described above, and the main body portions 10, 40 -17- (14) (14) M269875 are liquid-retaining sheets 11 made of a non-woven fabric having liquid-absorption and holding capabilities. 31 is composed of an inner surface sheet 12 and a pressure-sensitive adhesive 13. Therefore, it is possible to form a thin type and constitute a soft whole. When the stiffness is within the above range, the panty liners 1 and 30 are adhered to the inner surface of the thigh cloth of the panty through the pressure-sensitive adhesive layer 13 and the shape of the panty liner can be deformed by following the deformation of the panty. The person wearing it is not susceptible to the discomfort of the interfemoral part. Under the above-mentioned stiffness, the underpants linings 1 and 30 can have the same feel as the underpants when worn. In addition, because the stiffness is more than 40 mm, it is easy to maintain the shape of the panty liners 1 and 30. For example, when peeling off the peelable sheet 20 and holding the central part with fingers, it will not stick to the thigh cloth of the panty. The leading edge portion 1 a and the trailing edge portion 1 b are caused to sag by a large deflection of 80 degrees or more. Therefore, it is possible to prevent problems such as adhesion of the inner sheet 12 to each other through the pressure-sensitive adhesive layer 13 and to securely adhere the panty liners 1 and 30 to the thigh portion of the panty in the thigh cloth of the panty The surface compressibility is within the above range. When the liquid-retaining sheets 11 and 31 are partially pressed from the skin-side surface, the peripheral elasticity is restored, and it is not easy to cause depression and the like in the pressed part. Therefore, at the same time, the overall shape of the nail is not locally changed by pressing the tip of the nail at the same time. As shown in FIG. 6, the panty liners 1 and 30 are superimposed on the peelable sheet 20 with the wrapping paper for individual packaging in a state where the peelable sheet 20 is adhered, and the whole is in a three-layer overlapping state, or folded into Packed in 2 layers. When the packaging state is continued for a long period of time, the local compressive force on the liquid-retaining sheets 11 and 31 is exerted on the folded line portion. However, when -18- (15) M269875 shrinkage recovery is within the above range, when the package is opened _, 30, the fold line part does not easily leave large depressions, and the dimension is relatively free, so it has β of the fold line. Fibers are concentrated and aggregated. As described above, the skin side surface can be maintained during use, and it is not easy to cause discomfort in the mouth or the periphery. In addition, the present creation is not limited to the qualitative distribution of the skin-side surface points of the mold sheets 1 1 and 3 1 implemented as described above. The stiffness and compression recovery are adjusted. The results are shown in Table 1 of the above-mentioned Example (1). Examples and Comparative Examples In each of the examples and comparative examples, the resin film constituting the inner sheet was adhered to the fabric to form the same conditions. In addition, the thickness of the adhered liquid-retaining sheet was measured, and the stiffness was measured by the cantilever method.

The MD in Table 1 was measured using a test piece 63 having a length of 140 mm in the MD of the Examples and Comparative Forces, and the CD was measured using a test piece having a length of 140 mm in the CD of the Examples. In addition, although the length of the comparative example was less than 140 mm, the measurement was performed in the same manner as in the example except for the length. (Compression recovery) The compression characteristics of the above examples and comparative examples were measured with an automatic compression tester "KES FB-3A" manufactured by KATO TECH. The measurement line graph is not the same as that in FIG. 8. The above-mentioned automatic compression tester is provided with a sample in which a liquid-retaining sheet and an inner sheet are bonded. An initial pressure P 0 = 49 P a (0.5 g / cm 2) was applied to the vertical sample from the skin-side surface by a circular pressure plate having an area of 2 cm2, and the measured thickness at this time was taken as the initial thickness T0. Taking the initial pressure p0 as a starting point, the compression pressure was linearly increased at a compression speed of 50 seconds / 1 mm to Pm = 4900Pa (50g / cm2), and the measurement test piece at the time of applying the compression pressure Pm was pressurized. The thickness is Tm. Compression workload WC is a curve with respect to (丨) in Fig. 8 and 定 (N · m / m2) with definite integral between TO—Tm with WO〗 P · dT (P is pressure and T is thickness). . The compression recovery workload w C is a curve with respect to (i i) when the compression force is returned from P m to P 0, and 値 (N · m / m 2), which is integrally determined as described above, is performed. The compression recovery rate (RC) is obtained as W C ′ / W C (%). However, in Table 1, the average radon measured for 5 samples was used as the compression recovery rate (RO). Therefore, the RC stringency in Table 1 was 27-27 M269875 (24) W C ′ / W C (%).
