(6) 1233350 根據本發明，將夜用之生理用衛生棉裝著於衛生棉裝 著部並於穿著時欲將生理褲朝上拉時，微伸縮部是以與胯 下部縫合之點作爲基點而被上提。而，將該微伸縮部往上 拉之力量，是被作爲將胯下部往上拉之力量而發揮作用， 作爲把被裝著於衛生棉裝著部之夜用生理用衛生棉上提之 動力。此時，微伸縮部之縱向方向之拉伸係數因比微伸縮 部附近之優良伸縮部還大，故有效地發揮其作爲把與微伸 縮部連接之胯下部，再加上裝著於胯下部之生理用衛生棉 往上拉之力量之作用。因此，不會有如以往之後身片中心 部具備有拉伸性之生理褲般，即使抓住腰圍部往上拉亦僅 是所謂後身片之中心部伸長，而不易發揮作爲將生理用衛 生棉往上拉之力量之作用之情形，故夜用之厚型生理用衛 生棉會變得易於合貼於股胯部或臀溝。 該微伸縮部之拉伸性，其縱向方向之拉伸係數（拉伸 荷重除以拉伸率而得之者）爲10N〜6 0N左右，更較佳爲 2 ON〜5 ON左右。若拉伸係數小於10N則作爲上提生理用 衛生棉之力量不足夠，在將生理褲往上提拉時，會拉伸太 大不能有效作爲上提生理用衛生棉之力量以發揮作用。若 大於6 ON時，易於產生超過使生理用衛生棉合貼以上之 上提力，因生理用衛生棉會以比超過需求以上之力朝向身 體咬入，產生不適感或疼痛故不佳。又，例如像乙烯塑帶 或繩索等般即使拉伸，材料本身也不會伸長之場合，因將 生理褲往上提拉之力量會直接作爲上提生理用衛生棉之力 而產生作用，故會使生理用衛生棉過於咬入身體之縫隙， -10- 1233350 (7) 亦不理想。 在此’所謂微伸縮部之縱向方向以及優良伸縮部之縱 向方向，是指將生理褲裝著上時之上下方向（第1圖及第 2圖之Y方向），是從股胯部以及腿圍開口部朝向腰圍部 方向之意。又，所謂股胯部是指身體之臀下之間之意，包 含膣口、會陰部、肛門等之部位。又，所謂拉伸係數，是 指把用後述之方法拉伸生理褲之各部位（微伸縮部、優良 伸縮部、衛生棉上提部、固定部）使其拉伸時之拉伸荷重 ’除以此時之拉伸率得到之値之意，拉伸係數越大越不易 拉伸。 (3 )針對於具備有前身片、及後身片、及以跨架於 上述前身片與上述後身片間之形態而設置之胯下部、及由 上述前身片之上緣部與上述後身片之上緣部所形成之腰圍 部，以及形成於上述前身片之兩側緣與上述後身片之兩側 緣下側之一對腿圍開口部，其上述胯下部被作爲生理用衛 生棉之裝著部之生理褲，其特徵爲：於上述胯下部之大致 中央領域具備有從上述前身片跨越到上述後身片設置之衛 生棉上提部，該衛生棉上提部之縱向方向之拉伸係數，比 構成上述胯下部之臀下布材之縱向方向之拉伸係數還大之 生理褲。 根據本發明，衛生棉上提部，由於其縱向方向之拉伸 係數比周邊之臀下布材還大，故衛生棉上提部以比其周邊 之織布更強之力量往上拉，而發揮其將裝著於胯下部之生 理用衛生棉之中央部朝上側（身體之股胯部側）拉提之作 -11 - (8) 1233350 用。又，該衛生棉上提部之伸長性，爲其拉伸係數在5N 〜3 0N左右，更佳爲10N〜2 5N左右。若拉伸係數小於5N 則對於來自微伸縮部之上提力，不能有效發揮作爲將生理 用衛生棉之中央部上提之力之作用。又，如（1 )所述， 因胯下部是以跨架於前身片與後身片間之形態而設置，故 於穿著時會變成存在於恥骨附近及比肛門更後面之附近， 於該胯下部裝著生理用衛生棉，並穿上生理褲之時，由於 可使生理用衛生棉安定地裝著於胯下部，故不會產生褶縐 ，無經血漏出之虞慮。又，藉由在構成胯下部之臀下布材 之內側，將附有防水機能之防水布，僅於其前端部與後端 部使其與本體縫合’以防止漏出，且於設置有可收納衛生 棉側翼之衛生棉裝著布之場合，由於可使其對其臀下布材 及前身片、後身片之縫合部再縫合，故可減少縫合處，穿 著時沒有不安定感、不會損害外觀。在此，所謂衛生棉上 提部之縱向方向，是指朝向前身片與後身片間之方向之意 〇 (4 )針對於具備有前身片、及後身片、及以跨架於 上述前身片與上述後身片間之形態而設置之胯下部、及由 上述前身片之上緣部與上述後身片之上緣部所形成之腰圍 部’以及形成於上述前身片之兩側緣與上述後身片之兩側 緣下側之一對腿圍開口部，其上述胯下部被作爲生理用衛 生棉之裝著部’並在由伸縮性良好之構件所構成之優良伸 縮部之中’設置有由具些微伸縮性之構件所構成之微伸縮 部之生理褲，其特徵爲：上述微伸縮部，於上述後身片之 1233350 (9) 大致中央領域，以從上述胯下部朝向上述腰圍部之方式被 設置’於上述胯下部之大致中央領域設置有從上述前身片 跨越至上述後身片之衛生棉上提部，上述微伸縮部與上述 衛生棉上提部’於上述胯下部之上述後身片側之端部處被 縫合一起，上述微伸縮部之縱向方向之拉伸係數，比上述 優良伸縮部之縱向方向之拉伸係數還大，上述衛生棉上提 部之縱向方向之拉伸係數，比構成上述胯下部之上述臀下 布材之縱向方向之拉伸係數還大之生理褲。 根據本發明’如上述（2)及（3)所述，在穿著生理 褲時之將微伸縮部往上拉之力，會變成提拉衛生棉上提部 之力而產生作用。又，衛生棉上提部被比其周邊之臀下布 材更強之力往上拉，作爲把裝著於胯下部之生理用衛生棉 之中央部被朝上側（身體之股胯部側）提拉之力而產生作 用。因此’可使生理用衛生棉於股胯部更合貼地固定。又 ，如（1 )所述，因胯下部是以跨架於前身片與後身片間 之形態而設置，故會變成在穿著時存在於恥骨附近及比肛 門更後面之附近，於該胯下部裝著生理用衛生棉，並穿上 生理褲之時，由於可使生理用衛生棉安定地裝著於胯下部 ，故不會產生褶縐，無經血漏出之虞慮。 (5)上述胯下部’爲由被縫合於上述前身片及上述 後身片之上述臀下布材所構成者。 根據本發明，於臀下中間部不存在朝寬幅方向（朝向 一對腿圍開口部間之方向）之縫合部，而分別於前身片與 臀下布材前端部，以及後身片與臀下布材後端部之處存在 -13- 1233350 (10) 有縫合部。而，各別之縫合部，於穿著時存在於恥骨附近 及比肛門更後面之附近。因此，於裝著生理用衛生棉之時 ，由於可在該臀下布材安定地穿著之，故不會褶縐，無經 血漏出之虞。 (6) 上述生理褲，在上述腰圍部附近更具備有跨越 上述後身片及上述前身片而設置之腰圍保持部。 根據本發明，因腰圍保持部會使微伸縮部之往上提拉 之力或固定部之固定力分散於生理褲之橫向方向（寬幅方 向），並藉腰圍保持部保持之，故可使生理褲以較寬之面 積合貼於腰圍。 (7) 上述生理褲，於上述前身片之大致中央領域具 備有在上述優良伸縮部之外側被縫合於上述胯下部及上述 腰圍保持部以及該優良伸縮部之固定部。 根據本發明，於穿著生理褲時受到微伸縮部之往上提 拉之力，而衛生棉上提部被朝後身片側拉伸時，固定部可 抑制前身片之優良伸縮部欲伸縮之情形。藉此，可消除衛 生棉上提部之前身片側受到微伸縮部及衛生棉上提部之影 響而被拉伸之情形因而被固定，故微伸縮部之往上拉之力 會直接成爲提拉衛生棉上提部之力，將生理用衛生棉朝身 體側上提，會變得更合貼於股胯部或臀溝。 (8 )上述微伸縮部，於縱向方向爲由非伸縮性之材 料所構成者。 根據本發明，因微伸縮部幾乎不具縱向方向之伸縮性 ’故將夜用之生理用衛生棉裝著於衛生棉裝著布，並將生 -14- (11) 1233350 理褲朝上拉欲穿上時，往上拉之力會成爲將生理用衛生棉 上提之力而有效產生作用。又，作爲微伸縮部者，可舉尼 龍纖維或聚酯纖維等之編織布，於其縱向方向不是以聚氨 基甲酸乙酯纖維等之具伸縮性之構件來構成，雖藉由編織 構造之變化而多少具備有伸縮性，不過不具備所謂構件所 產生之伸縮性之織布者。 (9 )上述衛生棉上提部，於縱向方向爲由非伸縮性 之材料所構成者。 根據本發明，因衛生棉上提部是與微伸縮部同爲幾乎 不具縱向方向之伸縮性，故欲穿上生理褲而朝上拉時，藉 由來自微伸縮部之往上拉之力，衛生棉上提部被比其周邊 之織布更強之力拉伸，而發揮作爲將生理用衛生棉之中央 部往上提拉之力之作用。又，作爲衛生棉上提部者，可舉 與微伸縮部同爲尼龍纖維或聚酯纖維等之編織布，於其縱 向方向不是以聚氨基甲酸乙酯纖維等之具伸縮性之構件來 構成，雖藉由編織構造之變化而多少具備有伸縮性，不過 不具備所謂構件所產生之伸縮性之織布者。 (1 〇 )上述衛生棉上提部，其縱向方向之拉伸係數比 上述微伸縮部之縱向方向之拉伸係數還小。 於穿著生理褲時’後身片之微伸縮部會發揮其一面拉 伸胯下部之衛生棉上提部，一面使生理用衛生棉合貼於身 體之作用。如果’衛生棉上提部具備有比微伸縮部更大之 縱向方向之拉伸係數時，在將生理褲往上提拉時，由於衛 生棉上提部不會伸縮，而後身片之微伸縮部會伸縮，故會 -15- (12) 1233350 變得不易發揮其作爲將生理用衛生棉朝向身體上提之力之 作用。 (1 1 )上述衛生棉上提部，從上述前身片側到上述後 身片側，其寬幅越來越窄。 根據本發明，衛生棉上提部受到微伸縮部之上提力會 被朝向後身片側拉伸，以埋塡身體縫隙之方式發揮其作爲 將衛生棉朝上側（身體之股胯部側）上提之力之作用。此 時，衛生棉上提部之寬幅，把縫合於設置在前身片之固定 部之部位（擋接於恥骨附近之部位）當作成最大，則從膣 口到會陰部、肛門附近爲漸漸變窄，因此會變得在裝著於 胯下部之生理用衛生棉之中央線上，產生從該周邊朝向上 之力量。而，藉由把縫合於固定部之部位之寬幅作成與股 胯間寬幅大致相同之寬度，可使擋接於恥骨附近之生理褲 之部位安定，於膣口附近可保持平衡。又，固定部側之寬 幅爲與會陰部或肛門附近同樣窄時，於穿上後，生理用衛 生棉之中心會移位，有從膣口等之中心移位之可能性故不 理想。 又，該衛生棉上提部之寬幅，把縫合於設置在前身片 之固定部之部位（擋接於恥骨附近之部位）當作成最大， 則從膣口到會陰部、肛門附近爲漸漸變窄，此外，把縫合 於設置在前身片之固定部之部位（擋接於恥骨附近之部位 )當作成最大，則從膣口到會陰部附近漸漸變窄，再者從 該膣口到肛門附近亦可變寬（不過比與固定部縫合一起之 部位之寬幅窄）。 -16 - 1233350 (13) (12 )上述衛生棉上提部之寬幅，爲20 ηΊ nl〜60 ηΊ m 〇 因衛生棉上提部之寬幅不是以細線存在，故力量不會 集中於1點，故於穿著時不會朝向身體咬入，或將生理用 衛生棉裝著於衛生棉裝著布之時，不會有中央部折彎變成 山型’而該頂點給予身體不適感之虞慮。 (13)上述固定部之縱向方向之拉伸係數，爲比上述 優良伸縮部之縱向方向之拉伸係數還大。 根據本發明，前身片中央部之固定部，是發揮作爲使 恥骨附近所擋接之生理褲之部位固定之力之作用，不過固 定部之縱向方向之拉伸係數，因比優良伸縮部之縱向方向 之拉伸係數還大，故可抑制欲朝向前身片之縱向方向延伸 之力。由於可藉由該固定部抑制延伸，故前身片之中央領 域不會受到微伸縮部或衛生棉上提部之影響而被拉伸，恥 骨附近所擋接之生理褲之部位會被固定。又，該固定部之 縱向方向之拉伸係數爲10N〜3 0N左右，較佳爲15N〜 2 5N左右。此爲’前身片之腹部是會因身體之動作而較易 變形之部分’故若爲完全無伸縮之織布時，前身片上端之 腰圍部會下滑，而有損害合貼性之虞。又，該固定部爲由 尼龍纖維及聚氨基甲酸乙酯纖維等構成之強力織網所構成 〇 在此，所謂固定部之縱向方向，是指在裝著生理褲時 穿上脫下之方向’爲從股胯部及腿圍開口部朝向腰圍部之 方向（第2圖所示之Y方向）之意。 -17- (14) 1233350 (1 4 )上述微伸縮部之腰圍部側之上端部，以與上述 腰圍保持部縫合成大致V字狀。 丰艮據本發明’從構成微伸縮部之織布材之腰圍保持部 至胯下部之長度，從與腰圍保持部縫合之V字狀之中央 部（V字之中央先端部）至胯下部之長度，比其左右端部 短。織布材較短者若與較長部分比較，因其拉伸時之拉伸 量較大’故當微伸縮部被朝向上側往上拉時，從V字狀 之中央部至胯下部之部位會被比其左右端部強之力往上拉 。因此’中央部不會鬆弛，會表現出上提生理用衛生棉之 力。 (1 5 )上述固定部之腰圍部側之上端部，爲與上述腰 圍保持部縫合成大致V字狀。 根據本發明，從構成固定部之織布材之腰圍保持部至 胯下部之長度，從與腰圍保持部縫合之V字狀之中央部 (V字之中央先端部）至胯下部之長度，比其左右端部短 。織布材較短者若與較長部分比較，因其拉伸時之拉伸量 較大，故如在上述之微伸縮部已說明般，當固定部被朝向 上側往上拉時，從V字狀之中央部至胯下部之部位會被 比其左右端部強之力往上拉。因此，中央部不會鬆弛，會 表現出上提生理用衛生棉之力。 (1 6 )於上述胯下部之內側，前後端部被縫合於該胯 下部，該中間部沒有被縫合。 根據本發明，因被縫合於胯下部之生理用衛生棉裝著 布沒有完全與胯下部形成一體，而是在胯下部之內側從胯 -18- 1233350 (15) 下部獨立開來，故衛生棉裝著布不會與胯下部一起朝向前 後方向（前身片側及後身片側之方向）被拉伸，或即使被 拉伸也僅些微，故可確實保持裝著生理用衛生棉。又，由 於前後端部被縫合於胯下部，可與構成胯下部之臀下布材 一同縫合故可減少縫合處，不會有穿著時之不安定感或不 會損害外觀。在此，所謂前後端部，是指衛生棉裝著布之 前身片側及後身片側之端部之意。 (17)上述衛生棉裝著布之長度，爲與構成上述胯下 部之上述臀下布材之長度同等或其以上。 根據本發明，在將生理褲往上拉穿著之時，由伸縮織 布材之臀下布材所構成之胯下部即使被拉伸，但因衛生棉 裝著布之長度較長故不會有延伸之情形，或即使被拉伸亦 僅些微，故可確實保持生理用衛生棉。又，胯下部被拉伸 時，衛生棉上提部被壓向股胯部側，生理用衛生棉會被壓 貼於股胯部。 (1 8 )於上述優良伸縮部及上述微伸縮部之交界，從 上述優良伸縮部到上述微伸縮部，其伸縮性漸減。 根據本發明，因伸縮性從優良伸縮部起漸漸減低，故 穿著生理褲往上拉時，微伸縮部之拉伸會漸漸減少，變得 合貼而不會有不適感。 (1 9 )於上述優良伸縮部及上述微伸縮部之交界，從 上述優良伸縮部到上述微伸縮部，其伸縮性爲不連續性地 變化者。 藉由微伸縮部之伸縮性作成從優良伸縮部到微伸縮部 -19- 1233350 (16) 爲不連續性變化者，可使優良伸縮部與微伸縮部之區畫分 明，其與沒有淸楚區畫（亦即，伸縮性爲連續性變化之時 )之情形作比較時，其合貼性降低，而生理用衛生棉之上 提效果良好。 (20 )使上述生理褲形成立體狀時之，從上述胯下部 至上述腰圍部之臀長，以及從上述腿圍開口部至上述腰圍 部之最短部之身長之尺寸比例，爲相對於上述臀長之100 ，上述身長爲80〜200。 根據本發明，由於身長較長，故設置於腿圍開口部之 腿圍帶不會緊束從腿部周圍至腰骨附近之部份，而是緊束 裝著者之大腿部。因此，腿圍帶引起之傾斜之上提力不 會作用於胯下部，故不會發生對股胯部之咬入。再者由於 在胯下部不會作用腿圍帶引起之較大之上提力，故，藉由 設置於後身片之微伸縮部，胯下部之生理用衛生棉可確實 被朝上側上提，會變得更合貼。 (2 1 )上述微伸縮部、及上述衛生棉上提部，以及上 述腰圍保持部，爲呈現與上述優良伸縮部不同之色調或光 澤者。 根據本發明，藉由微伸縮部、及衛生棉上提部，以及 腰圍保持部爲與優良伸縮部之顏色或質感不同，可一目了 然易於區別。如此藉由使腰圍保持部、微伸縮部，以及衛 生棉上提部一目了然，穿著者從此易於認出上提部，同時 易於充分感覺上提部之效果。又’設置於生理褲之大致中 央部之此等上提部，藉由在外觀與其他織布材之部分不同 •20- (17) 1233350 ’在將生理用衛生棉對位裝著於生理褲之時，生理用衛生 棉之中央部與生理褲之中央部易於對位，可使生理用衛生 棉之中央部準確合貼於身體之股胯部之中央部。藉此，可 提昇防止經血等液體漏出之塞縫效果。 (22)顯示穿著方法之標示設置於上述前身片或是上 述後身片。 . 根據本發明，穿著者，讀該標示可控制生理用衛生棉 之合貼性。亦即，將生理用衛生棉夾介黏著劑等裝著於生 理褲之衛生棉裝著布，並將該生理褲拉至身體之特定位置 穿著之時，要抓住生理褲之上脅部往上拉，不過用該穿著 方法’穿著生理褲時，具備有生理用衛生棉之某程度之密 接性。但是，由於密接度之喜好因人而異，欲使其更合貼 者’例如讀了所謂「藉由將後身片中央部之微伸縮部之延 長線上之部位往上拉，可得到更高之合貼性」之標示，可 得到自己喜好之密接性。如此，期望高密接性之人，於穿 著時可接受誘導而更易穿著。 (2 3 )上述標示，爲被設置於上述微伸縮部上側之上 述腰圍部之附近者。 根據本發明，藉由將所標示之部分往上拉可使生理用 衛生棉更合貼。亦即，藉由在抓住生理褲之上脅部裝著之 後，再將所標示之部分往上拉，微伸縮部會被上提。藉由 該微伸縮部被上提，如於先前所說明般，由於會成爲從身 體之股胯部側將生理用衛生棉強力往上壓，故可得到更高 之密接性。 -21 · (18) 1233350 【實施方式】 其次，參照圖面繼續說明本發明之生理褲之一實施形 態，不過本發明並非限定於此者。 說明關於本實施形態之生理褲之基本構成。第1圖是 顯示把沒有裝著於身體之本發明之生理褲之第1實施形態 ，以前身片與後身片相接之方式對折之狀態之正面圖，第 2圖是顯示對折狀態之背面圖，第3圖是從前身片側顯示 第1實施形態之裝著狀態之立體圖，第4圖從後身片側顯 示第1實施形態之裝著狀態之立體圖，第5圖是將第2圖 之實施形態之生理褲之微伸縮部放大之放大平面圖，第6 圖是從胯下部底面側觀察之部分平面圖，第7圖是顯示在 第6圖之衛生棉上提部之其他形態之部分平面圖，第8圖 是從胯下部內側顯示之部分立體圖，第9圖是胯下部之部 分側面圖，第1 〇圖是用以說明穿著本發明之生理褲時之 微拉伸部、衛生棉上提部以及固定部之舉動之說明圖，第 11圖是用以說明穿著本發明之生理褲時之膣口附近之生 理褲之舉動說明之圖，第1 2圖是顯示關於微伸縮部之拉 伸率與拉伸強度之關係圖。 如第1圖至第4圖所示，生理褲1〇，具備有前身片 1 1、及後身片1 2、及位於前身片1 1與後身片1 2間之胯 下部13、及由前身片n之上緣部與後身片12之上緣部 所形成之腰圍部1 4、及形成於前身片n與後身片1 2下 側之一對腿圍開口部1 5，以及於胯下部丨3之內側裝著生 -22- (19) 1233350 理用衛生棉之衛生棉裝著布I 6 (示於第8圖）；於腰圍 部1 4附近設置有跨越前身片n與後身片1 2之腰圍保持 部1 7 ’於後身片1 2之中央領域設置有從胯下部1 3朝向 腰圍保持部1 7之微伸縮部1 8，從除了腰圍保持部1 7之 外之微伸縮部1 8跨越至前身片1 1全區域設置有優良伸縮 部1 9 ’並被縫合於前身片1 1之大致中心線上。又，於前 身片1 1之中央領域，在優良伸縮部1 9之外側，設置有被 縫合於胯下部1 3、腰圍保持部1 7，以及優良伸縮部1 9上 之固定部2 0，於胯下部1 3之中央領域設置有從微伸縮部 1 8朝向固定部2 0之衛生棉上提部2 1。又，於前身片1 1 與後身片12之上端部之腰圍部14設置有腰圍帶22，於 腿圍開口部1 5設置有腿圍帶23。而，使生理褲1 0形成 立體狀時之從胯下部13至腰圍部14之臀長La及從腿圍 開口部1 5至腰圍部1 4之最短部之身長Lb之尺寸比例， 爲相對於臀長La之100，身長Lb爲80〜200之關係。 優良伸縮部1 9，例如，可由尼龍纖維與聚氨基甲酸 乙酯纖維、聚酯纖維與聚氨基甲酸乙酯纖維、尼龍纖維與 聚酯纖維與聚氨基甲酸乙酯纖維等之編織布材而形成。又 ，即使不是上述之纖維之組合’只要能作成拉伸係數在 10N以下，他之纖維使，亦可採用其他編法。又，胯下部 13是由臀下布材24所構成’該臀下布材24爲與優良伸 縮部1 9及胯下部1 3之前身片Π側在後身片1 2側被縫合 。該臀下布材24與優良伸縮部19同樣爲藉由尼龍纖維與 聚氨基甲酸乙酯纖維、聚酯纖維與聚氨基甲酸乙酯纖維、 -23- 1233350 (20) 尼龍纖維與聚酯纖維與聚氨基甲酸乙酯纖維等編織而成之 可自由彈性伸縮之織布所形成。又，設置於腰圍部1 4之 腰圍帶22及設置於腿圍開口部15之腿圍帶23，是由用 聚氨基甲酸乙酯纖維所形成之伸縮性織布、合成橡膠薄片 、天然橡膠薄片等所形成。在此，所謂縱向方向，是指把 腰圍部1 4及胯下部1 3以及腿圍開口部1 5作爲上下之方 向（第1圖所示之Y方向），爲裝著生理褲10時穿上脫 下之方向之意’所謂橫向方向，是指與縱向方向垂直相交 之方向（第1圖所示之X方向），爲生理褲ίο之寬幅方 向之意。 腰圍保持部1 7，於生理褲1 〇之腰圍部1 4附近朝向 前身片11及後身片12之中央部被形成爲大致V字狀， 並被縫合於前身片11及後身片12之優良伸縮部19。該 腰匱I保持部1 7 ’爲其朝向縱向方向之拉伸係數比朝向橫 向方向之拉伸係數強之編織布，是由尼龍纖維與聚氨基甲 酸乙酯纖維、聚酯纖維與聚氨基甲酸乙酯纖維、尼龍纖維 與聚_纖維與聚氨基甲酸乙酯纖維等之編織布所形成。又 ，設置於腰圍部1 4上端部之腰圍帶22爲約1 0 m m左右 之聚氨基甲酸乙酯帶、天然橡膠帶、合成橡膠帶等，且於 拉伸狀態被縫合於腰圍保持部1 7。 該腰圍保持部1 7，爲把藉由微伸縮部1 8或固定部20 之上提衛生棉上提部2 1之力予以分散，在腰圍部達到保 持之角色功能者’以穿著時可卡在腰上而得到固定之於縱 向方向之延伸受到抑制者爲理想。又，橫向方向之拉伸係 -24 -

Physiological pants that are shifted and have an excellent fit to the body, and at the same time, it is not easy to produce tightness and discomfort. [Prior art] The physiological pants must be required to be able to securely hold the physiological sanitary napkin mounted on the lower part of the crotch on the femoral part of the body without moving, and prevent the displacement of the physiological sanitary napkin on the femoral part. , And reduce the bite into the crotch, good wear. As this kind of physiological pants, it is disclosed in Japanese Patent Document 1 that a portion having a large tensile load is provided in the central area of the front body piece and the back body piece, and is provided between the front body piece and the back body piece, and the front body piece is provided. The thigh area and the pair of elastic leg openings which are joined to the back body piece are provided with a stretch control member in the long side direction in the thigh area, and the front body piece and the back body piece are provided with the long side direction. The stretch control member extends to the stretch control member of the waistband. In addition, the present inventors have provided the physiological pants disclosed in Japanese Patent Document 2. The purpose of the physiological pants is to provide physiological pants which are easy to fit physiological sanitary napkins to the femoral region, reduce bite into the femoral region, and have a good wearing feeling. The leg pants are provided, and the lower part of the hip is used as the wearing part of the sanitary napkin. The physiological pants are formed from the lower part of the hip to the waist when the three-dimensional shape of the physiological pants is formed. ) The ratio of the length of the shortest part from 1233350 to the waist is 100 relative to the hip length. The above length is 80 ~ 200, and the upper body is provided with a lifting elastic member from the lower part of the hip to the waist. [Japanese Patent Document 1] Japanese Unexamined Patent Publication No. 200 1 -52295 [Japanese Patent Document 2] Japanese Unexamined Patent Publication No. 2002-660 [Summary of the Invention] [Technical Problems to be Solved by the Invention] However, Japanese Patent Document 1 Although the physiological sanitary napkin placed in the thigh area can be tightly attached to the body by stretching the control member, because the stretching control member exists in a thin line as shown in the bulletin, the force is concentrated At a linear point, a bite toward the body occurs when worn, or a sanitary napkin is bent at the center to form a mountain shape, and the bent apex may give a sense of discomfort to the body. In addition, since the front body piece and the back body piece are sewn to form two elastic leg openings, the stitching portion is formed in a wide direction toward a pair of leg circumference openings in a central portion below the buttocks. Therefore, when the physiological sanitary napkin is mounted on the physiological pants, the base on which the physiological sanitary napkin is stably held does not exist, because the physiological sanitary napkin is twisted and narrowed, or the adhesive part of the physiological sanitary napkin is removed from the physiological Due to the peeling of the pants body, there is a high possibility that the so-called leakage may occur. Also, in Japanese Patent Document 2, the elastic structure is provided on the back body piece. 6- (3) 1233350 pieces will play in the longitudinal direction. The elastic contraction force, but the elastic contraction force acts almost along the spinal cord in the central part of the back body piece, and roughly linearly acts along the depression in the center of the buttocks and the femoral region. Therefore, when the elastic member is lifted on the rear suture portion, the size of the buttocks cloth is divided into half of the central line portion, which exerts a large tensile force in the front and back direction of the buttocks cloth, and uses the physiological properties of the lower crotch. The tampon is pressed against the mouth. However, this physiological pant has a structure in which the elastic member provided on the back body sheet stretches elastically in the longitudinal direction and fits the sanitary napkin to the body. However, since the elastic member is provided on the back body sheet, The front body piece is made of a woven fabric with sufficient elasticity. Therefore, when a thick sanitary napkin for night use is installed, the physiological sanitary napkin can be lifted up and fit to the body even by the elastic member of the back body piece. Because the sanitary napkin is very thick and rigid, and the elastic member is excessively stretched, it cannot be used as a force for pressing the sanitary napkin, and it cannot be fully adhered to the buttocks or femoral crotch. Therefore, a gap is created between the sanitary napkin and the body, and menstrual blood may leak out from the sanitary napkin along the buttocks. In addition, the menstrual blood generated through the gap spreads to increase the menstrual blood that comes in contact with the skin, which may cause a large burden on the skin and may cause a rash. In addition, the body moves inadvertently during sleep. If the tampon is tightly pressed against the tampon with a tight tampon to prevent the displacement or crease of the sanitary napkin, it will cause swelling or impede the blood. The fear of circulation creates a lot of stress on the body. Therefore, instead of tightly binding the whole body, the physiological pants of the structure in which the sanitary napkins must be pressed and fitted to the body only partially must be expected. 1233350 (4) In view of the above-mentioned problems, the present invention aims to provide a thick sanitary napkin for night use that can easily adhere to the crotch or gluteal groove, and can prevent displacement and reduce The bite into the crotch of the crotch's overalls without tight tightness, wearing good physiological pants. [Technical Means for Solving the Problem] The present invention was created to focus on such a conventional problem point. It is composed of a good stretchable part made of a good stretchable member, and a tiny part made of a small stretchable member. The bottom part of the physiological pants formed by the telescopic part is provided across the front body part and the back body part, and the micro-stretching part is distributed from the rear end part of the lower part to the waist holding part of the back body part. In the central area, the tensile coefficient in the longitudinal direction is made larger than the tensile coefficient in the longitudinal direction of a good stretchable portion covering the periphery of the buttocks or abdomen. In the central area of the lower part of the crotch, a sanitary napkin upper part connected to the micro-stretching part of the back body piece is provided. The structure in which the stretch coefficient of the cloth material in the buttocks in the longitudinal direction is still large is to solve the above-mentioned problems and to complete the present invention. More specifically, the present invention provides the following. (1) It is composed of a good stretchable part made of a good stretchable member, and a micro-stretchable part made of a less stretchable member, and it has a front body piece, a rear body piece, and a cross frame. The lower part of the crotch provided in the form between the front body piece and the rear body piece, and the waistline portion formed by the upper edge portion of the front body piece and the upper edge portion of the rear body piece, and formed in the aforementioned -8-1233350 ( 5) A pair of leg openings on one of the sides of the front body and the lower side of the sides of the back body; in the approximate central area of the back body, the micro-stretching portion is allocated from the lower part of the hip to the waist Physiological trousers in a belt-shaped area provided by the department. According to the present invention, when the physiological pants are to be pulled upwards, the micro-stretching portions allocated to a certain area provided from the lower part of the crotch toward the waistline part do not expand and contract, but play the role of lifting the lower part of the crotch connected thereto. As a result, the physiological sanitary quilt mounted on the lower part of the chin is lifted and becomes fit to the femoral chin or gluteal sulcus on the side of the body, making it difficult to create a gap between the physiological sanitary napkin and the body, preventing menstrual blood and the like. leakage. In addition, since the physiological pants are composed of excellent stretchable portions with good stretchability, the overall tightness is not as tight as the belly, and the wearing feeling is good. In addition, since the lower part of the crotch is provided in the form of being straddled between the front body sheet and the back body sheet, it will exist near the pubic bone and near the back of the anus when worn. When the physiological pants are put on, since the sanitary napkins can be stably mounted on the lower part of the crotch, there is no crease and there is no fear of menstrual blood leakage. Here, the front body part refers to the front part of the body part of the physiological pants, covering the abdomen, and the back body part refers to the back part of the body part of the physiological pants, covering the back side of the waistline. In addition, the so-called large body film refers to the part covering the waistline of the body. In addition, the so-called lower part of the chin is set to span the front body and the back body. It does not mean that the front body and the back body are directly connected to form the lower body, but it means that the buttocks are sewn to the front body. The film and back body piece are connected to form the lower part of the chin. (2) The micro-elastic portion has a tensile coefficient in a longitudinal direction which is larger than a longitudinal coefficient of the excellent elastic portion. -9-(6) 1233350 According to the present invention, when the sanitary napkin for night use is mounted on the sanitary napkin and the physiological pants are pulled upwards when wearing, the micro-stretching section is stitched with the lower part of the chin. The point is raised as a base point. The force of pulling up the micro-stretching part is used as a force for pulling up the lower part of the palate, and as a motive force for lifting the night-use physiological sanitary napkin that is placed on the sanitary napkin installation section. . At this time, the stretch factor in the longitudinal direction of the micro-stretched portion is larger than that of the excellent stretched portion near the micro-stretched portion, so it can effectively play its role as the lower part of the joint connecting with the micro-stretched part, and it is mounted on the lower part The effect of the power of pulling up with a sanitary napkin. Therefore, it will not be as if the central part of the body part had stretchable physiological pants in the past. Even if the waist part is grasped and pulled up, it is only the center part of the so-called back body part, which is not easy to be used as a sanitary napkin. Due to the effect of the upward pulling force, the thick sanitary napkin used at night will become easy to fit on the femoral region or gluteal groove. The stretchability of the micro-stretched portion is about 10N to 60N, and more preferably about 2 to 5 ON, in a longitudinal direction (a tensile coefficient divided by a tensile load). If the stretching coefficient is less than 10N, it is not enough as a force for lifting the sanitary napkin. When the physiological pants are pulled upward, it will be stretched too much to effectively function as a force for lifting the sanitary napkin. If it is more than 6 ON, it is easy to generate a lifting force exceeding that of a physiological sanitary napkin, and the physiological sanitary napkin may bite into the body with a force more than required, causing discomfort or pain. For example, if the material itself does not stretch even if it is stretched, such as a vinyl band or a rope, the force of pulling up the physiological pants will directly act as the force for lifting the sanitary napkin, so -10- 1233350 (7) will cause the sanitary napkin to bite into the gap of the body too much. Here, the longitudinal direction of the micro-stretching portion and the longitudinal direction of the good-stretching portion refer to the up and down direction when the physiological pants are worn (the Y direction in FIG. 1 and FIG. 2), and are from the femoral region and the legs It means that the circumference opening part is oriented toward the waistline part. In addition, the so-called femoral region refers to the area between the hips of the body, and includes the mouth, perineum, and anus. In addition, the so-called stretch coefficient refers to the division of the tensile load when stretching various parts of the physiological pants (micro-stretchable portion, excellent stretchable portion, tampon lifting portion, and fixing portion) by a method described later. The meaning obtained by the elongation at this time is that the larger the stretch coefficient, the harder it is to stretch. (3) For a front part and a back part, and a lower part provided in a form of being straddled between the front part and the back part, and an upper edge of the front part and the rear part The waistline portion formed by the upper edge portion of the sheet, and the pair of leg circumference openings formed on one of the two side edges of the front body piece and the lower side of the two side edges of the rear body piece, and the lower part of the palate is used as a sanitary napkin. The physiological pants of the wearing part is characterized in that a sanitary napkin upper lifting portion provided from the front body piece to the rear body piece is provided in a substantially central area of the lower part of the crotch, and The stretch factor is a physiological pants which is larger than the stretch factor in the longitudinal direction of the lower hip fabric. According to the present invention, since the tensile coefficient of the upper portion of the sanitary napkin is larger than that of the cloth material of the buttocks of the periphery, the upper portion of the sanitary napkin is pulled upward with a stronger force than the cloth of the periphery. It is used for lifting the center part of the physiological sanitary napkin placed on the lower part of the chin toward the upper side (the side of the femoral part of the body) -11-(8) 1233350. In addition, the elongation of the upper lifting portion of the sanitary napkin has a stretch coefficient of about 5N to 30N, more preferably about 10N to 2N. If the stretching coefficient is less than 5N, the lifting force from the micro-stretching portion cannot effectively exert the effect of lifting the central portion of the sanitary napkin. Also, as described in (1), since the lower part of the iliac crest is placed between the front body piece and the rear body piece, it will exist near the pubic bone and near the back of the anus when worn. A physiological sanitary napkin is mounted on the lower part, and when the physiological pants are put on, the physiological sanitary napkin can be stably mounted on the lower part of the chin, so there is no crease and there is no fear of menstrual blood leakage. In addition, a tarpaulin with a waterproof function is attached to the inside of the buttock cloth material constituting the lower part of the chin, and is sewn to the body only at the front end portion and the rear end portion to prevent leakage. When the sanitary napkin on the side of the sanitary napkin is clothed, it can be re-stitched on the cloth under the hips and the stitches on the front and back panels, so the stitching can be reduced. Damage the appearance. Here, the vertical direction of the upper part of the sanitary napkin refers to the direction between the front body piece and the back body piece. (4) It is aimed at having a front body piece and a back body piece and straddling the front body. The lower part of the crotch provided between the sheet and the back body piece, and the waist portion formed by the upper edge portion of the front body piece and the upper edge portion of the back body piece, and the side edges of the front body piece and One pair of leg openings on the lower side of the side edges of the rear body piece, and the lower part of the crotch is used as a fitting portion of a sanitary napkin 'and in a good stretchable portion made of a highly elastic member' The physiological pants provided with a micro-stretchable portion composed of some micro-stretchable members are characterized in that: the micro-stretchable portion is located in a substantially central area of 1233350 (9) of the rear body piece so as to face the waistline from the lower part of the hip The method is provided in the central portion of the lower part of the crotch. A sanitary napkin lifting part is provided from the front body sheet to the rear body part. The micro-stretching part and the sanitary napkin lifting part are provided in the lower part of the crotch. The above back The ends at the sides are stitched together. The tensile coefficient in the longitudinal direction of the micro-stretched portion is larger than the tensile coefficient in the longitudinal direction of the excellent stretched portion. The tensile coefficient in the longitudinal direction of the upper lifting portion of the sanitary napkin. Physiological pants having a tensile coefficient greater than the longitudinal direction of the buttocks cloth material constituting the lower part of the palate. According to the present invention, as described in (2) and (3) above, when the physiological pants are worn, the force of pulling the micro-stretching portion upwards becomes the force of pulling the upper portion of the sanitary napkin and exerts its effect. In addition, the upper part of the sanitary napkin is pulled upwards by a stronger force than the cloth material around the buttocks of the periphery, and the central part of the sanitary napkin attached to the lower part of the crotch is turned upward (the side of the thigh part of the body). Lifting force works. Therefore, 'the sanitary napkin can be fixed to the femoral palate more closely. Also, as described in (1), since the lower part of the iliac crest is placed between the front body piece and the rear body piece, it will exist near the pubic bone and behind the anus when it is worn. A physiological sanitary napkin is mounted on the lower part, and when the physiological pants are put on, the physiological sanitary napkin can be stably mounted on the lower part of the chin, so there is no crease and there is no fear of menstrual blood leakage. (5) The lower crotch 'is composed of the buttocks cloth material sewn to the front body sheet and the rear body sheet. According to the present invention, there is no suture in a wide direction (toward a pair of leg openings) in the middle part of the buttocks, but in the front part of the front piece and the lower part of the cloth, and the back part and the buttocks, respectively. -13-1233350 is present at the rear end of the lower fabric. (10) There is a seam. In addition, the respective suture portions exist near the pubic bone and near the back of the anus when worn. Therefore, when the sanitary napkin is installed, the cloth can be worn stably under the buttocks, so there is no crease and no menstrual blood leaks out. (6) The physiological pant further includes a waist-retaining portion provided across the back body piece and the front body piece near the waistline portion. According to the present invention, since the waist holding portion can disperse the upward pulling force of the micro-stretchable portion or the fixing force of the fixing portion in the lateral direction (wide direction) of the physiological pants, and is held by the waist holding portion, it can be made The physiological pants fit to the waist with a wide area. (7) The physiological pants is provided at a substantially central area of the front body piece, and is provided with a fixed portion which is sewn to the lower part of the hip and the waist-retaining portion and the excellent elastic portion outside the excellent elastic portion. According to the present invention, when the micro-stretching portion is pulled upwards while wearing the physiological pants, and the upper portion of the sanitary napkin is stretched toward the back body piece side, the fixing portion can restrain the excellent stretch portion of the front body piece from being stretched. . This can eliminate the situation where the side of the body piece before the upper part of the sanitary napkin is stretched due to the influence of the micro-extensible part and the upper part of the sanitary napkin and is thus fixed. Therefore, the pull-up force of the micro-extensible part will be directly pulled The strength of the upper part of the sanitary napkin will lift the sanitary napkin toward the body side, and it will become more fit to the femoral region or the gluteal groove. (8) The micro-stretching portion is made of a non-stretchable material in the longitudinal direction. According to the present invention, since the micro-stretching portion has almost no elasticity in the longitudinal direction, the night-use sanitary napkin is mounted on a sanitary napkin with a cloth, and the raw -14- (11) 1233350 pants are pulled upwards. When you put it on, the pull-up force will become the force that lifts the sanitary napkin. As the micro-stretchable portion, a woven fabric such as nylon fiber or polyester fiber may be used. In the longitudinal direction, it is not constituted by a flexible member such as polyurethane fiber. And weavers that have stretchability, but do not have the so-called stretchability produced by members. (9) The upper part of the sanitary napkin is made of a non-stretchable material in the longitudinal direction. According to the present invention, since the upper part of the sanitary napkin has the same stretchability as the micro-stretching part with almost no longitudinal direction, it is necessary to pull up from the micro-stretching part when pulling on the physiological pants and pulling upward, The upper lifting part of the sanitary napkin is stretched by a stronger force than the woven fabric around it, and exerts its function of pulling up the central part of the sanitary napkin. In addition, as the upper lifting part of the sanitary napkin, a woven fabric that is the same as the micro-stretching part, such as nylon fiber or polyester fiber, may be used. The longitudinal direction of the woven fabric is not made of a flexible member such as polyurethane fiber. Although weaving is somewhat flexible due to changes in the weaving structure, weavers do not have the so-called stretchability produced by members. (10) The above-mentioned lifting portion of the sanitary napkin has a tensile coefficient in the longitudinal direction smaller than that in the longitudinal direction of the micro-stretching portion. When wearing the physiological pants, the micro-stretching part of the 'back body piece will play the role of stretching the upper part of the sanitary napkin at the lower part of the back, while making the sanitary napkin fit to the body. If the upper part of the sanitary napkin has a larger longitudinal coefficient than the micro-stretchable part, when the physiological pants are pulled up, the upper part of the sanitary napkin will not expand and contract, and the back part will slightly expand and contract. -15- (12) 1233350 becomes difficult to exert its function as a force for lifting a sanitary napkin toward the body. (1 1) The width of the upper portion of the sanitary napkin is narrower from the front body side to the rear body side. According to the present invention, the upper lifting portion of the sanitary napkin is stretched toward the back body side by the lifting force of the micro-stretching portion, and exerts its function as a body gap by placing the sanitary napkin on the upper side (the side of the thigh portion of the body). The power of mentioning. At this time, the width of the upper lifting part of the sanitary napkin is taken as the largest, and the part fixed to the fixed part of the front body (the part near the pubic bone) is taken as the largest. Then it gradually changes from the mouth to the perineum and the anus. It is narrow, so it will become a force from the periphery to the center line of the sanitary napkin mounted on the lower part of the crotch. In addition, by making the width of the sutured part fixed to the fixed part to be approximately the same as the width of the femoral condyle, the position of the physiological pants which is close to the pubic bone can be stabilized, and the balance can be maintained near the condyle. When the width on the side of the fixed part is as narrow as near the perineum or the anus, the center of the physiological cotton is shifted after being put on, and it may be shifted from the center of the mouth or the like, which is not desirable. In addition, the width of the upper lifting part of the tampon is taken as a maximum, and the portion from the mouth to the perineum and the anus is gradually changed from the mouth to the perineum and the anus. It is narrow, and the part that is sutured to the fixed part of the front body (the part near the pubic bone) is regarded as the largest, and then it narrows from the mouth to the perineum, and then from the mouth to the anus. It can also be widened (but narrower than the width of the area stitched with the fixed part). -16-1233350 (13) (12) The width of the upper part of the sanitary napkin is 20 ηΊ nl ~ 60 ηΊ m 〇 Because the width of the upper part of the sanitary napkin does not exist as a thin line, the strength will not focus on 1 Point, so when you wear it, you wo n’t bite into your body, or when you put a sanitary napkin on a cloth, you wo n’t bend the central part into a mountain shape. consider. (13) The tensile factor in the longitudinal direction of the fixed portion is larger than the tensile factor in the longitudinal direction of the excellent stretchable portion. According to the present invention, the fixing part of the central part of the front body piece plays a role of fixing the position of the physiological pants blocked near the pubic bone, but the longitudinal coefficient of the fixing part is longer than that of the good elastic part. The stretch factor in the direction is also large, so it is possible to suppress the force to extend in the longitudinal direction of the front body piece. Since the extension can be restrained by the fixing portion, the central area of the front body piece will not be stretched by the influence of the micro-stretching portion or the upper portion of the sanitary napkin, and the portion of the physiological pants blocked near the pubic bone will be fixed. The tensile coefficient of the fixed portion in the longitudinal direction is about 10N to 3N, and preferably about 15N to 2N. This is “the abdomen of the front body piece is easily deformed due to the movement of the body”. If it is a non-stretchable woven fabric, the waistline at the upper end of the front body piece will slide down, which may damage the fit. In addition, the fixing portion is made of a strong woven mesh composed of nylon fiber, polyurethane fiber, and the like. Here, the longitudinal direction of the fixing portion refers to the direction of putting on and taking off when wearing physiological pants. It means the direction from the crotch and leg opening to the waistline (Y direction shown in Fig. 2). -17- (14) 1233350 (1 4) The upper end of the waistline portion side of the micro-stretching portion is stitched with the waistline holding portion to form a substantially V shape. Fenggen according to the present invention 'from the length of the waist holding portion of the woven material constituting the micro-stretching portion to the lower part of the chin, from the V-shaped central portion (the central apex portion of the V-shape) stitched to the waist holding portion to the lower portion of the chin The length is shorter than the left and right ends. If the short woven material is compared with the longer part, the amount of stretch will be larger when it is stretched. Therefore, when the micro-stretched part is pulled upwards, from the V-shaped central part to the lower part of the chin Will be pulled upwards by more force than its left and right ends. Therefore, the 'central portion does not slacken and exerts the force to lift a sanitary napkin. (1 5) The upper end portion on the waist portion side of the fixing portion is formed in a substantially V-shape by sewing with the waist holding portion. According to the present invention, the length from the waist holding portion of the woven material constituting the fixing portion to the lower crotch portion, and the length from the V-shaped central portion (the central apex portion of the V shape) to the lower crotch portion sewn to the waist holding portion is smaller than Its left and right ends are short. If the short woven material is compared with the longer part, the amount of stretching is larger when it is stretched. Therefore, as described in the micro-stretching part described above, when the fixed part is pulled upwards from the upper side, the V The part from the center of the figure to the lower part of the chin is pulled upwards by a stronger force than its left and right ends. Therefore, the central portion does not become slack, and the force for lifting a sanitary napkin is exhibited. (16) On the inside of the lower part of the iliac crest, the front and rear ends are sutured to the lower part of the condyle, and the middle part is not sutured. According to the present invention, because the sanitary napkin cloths sewn to the lower part of the chin are not completely integrated with the lower part of the chin, but are separated from the lower part of the 胯 -18-1233350 (15) inside the lower part of the chin, so the sanitary napkin The cloth is not stretched in the front-to-rear direction (front body side and back body side) with the lower part of the chin, or even slightly stretched, so it is possible to keep the sanitary napkins in place. In addition, since the front and rear ends are sewn to the lower part of the chin, they can be sewn together with the cloth material constituting the lower part of the buttocks, so that the seam can be reduced, and there is no sense of instability or damage to the appearance when worn. Here, the front and rear end portions mean the ends of the front sheet side and the back sheet side of the sanitary napkin. (17) The length of the sanitary napkin cloth is equal to or longer than the length of the under hip cloth material constituting the lower crotch portion. According to the present invention, when the physiological pants are pulled upwards to be worn, even if the lower part of the hips made of the stretchable fabric under the hips is stretched, there is no longer the length of the sanitary cotton cloth. In the case of stretching, or even if it is stretched, it is only slightly, so the sanitary napkin can be reliably maintained. When the lower part of the crotch is stretched, the upper part of the sanitary napkin is pressed toward the side of the femoral region, and the sanitary napkin is pressed against the femoral region. (18) At the boundary between the excellent elastic portion and the micro-elastic portion, the elasticity gradually decreases from the excellent elastic portion to the micro-elastic portion. According to the present invention, since the stretchability is gradually reduced from the excellent stretchable portion, when the physiological pants are pulled up, the stretch of the microstretchable portion is gradually reduced, and it becomes fit without discomfort. (19) At the boundary between the excellent stretchable portion and the micro-stretchable portion, the stretchability from the excellent stretchable portion to the micro-stretchable portion changes discontinuously. By making the stretchability of the micro-stretchable part from the fine-stretchable part to the micro-stretchable part -19-1233350 (16) The discontinuity changes, which can make the area between the fine-stretchable part and the micro-stretchable part clear. Comparing the situation of the area painting (that is, when the elasticity is a continuous change), the fit is reduced, and the lifting effect of the sanitary napkin is good. (20) When the physiological pants are formed into a three-dimensional shape, the ratio of the length of the hips from the lower part of the hip to the waistline and the length from the leg opening to the shortest part of the waistline are relative to the hips. The length is 100 and the body length is 80 ~ 200. According to the present invention, since the body length is long, the leg girth provided at the opening of the leg circumference does not tightly bind the portion from the periphery of the leg to the vicinity of the lumbar bone, but tightly binds the thigh of the wearer. Therefore, the upward lifting force caused by the leg girth will not act on the lower part of the palate, so no bite into the femoral region will occur. In addition, since the large lifting force caused by the leg girdle does not act on the lower part of the chin, the sanitary napkin in the lower part of the chin can be surely lifted up by the micro-stretching portion provided on the back body piece. Will become more snug. (2 1) The micro-stretching portion, the sanitary napkin lifting portion, and the waist-retaining portion are those having a different hue or gloss from the excellent stretchable portion. According to the present invention, the micro-stretching portion, the tampon lifting portion, and the waist-retaining portion are different in color or texture from the excellent stretching portion, and can be easily distinguished at a glance. In this way, the waist-holding portion, the micro-stretching portion, and the sanitary cotton upper-lifting portion can be seen at a glance, so that the wearer can easily recognize the upper-lifting portion and feel the effect of the upper-lifting portion sufficiently. Also, 'these raised parts provided in the approximate central portion of the physiological pants are different in appearance from those of other woven fabrics. • 20- (17) 1233350' The physiological pants are placed in the physiological pants in a positional position. At this time, the central portion of the sanitary napkin and the central portion of the physiological pants are easy to align, so that the central portion of the sanitary napkin can be accurately fitted to the central portion of the thigh portion of the body. This can improve the effect of preventing the leakage of liquid such as menstrual blood. (22) A sign showing how to wear is set on the front body piece or the rear body piece. . According to the present invention, the wearer can read the label to control the fit of the sanitary napkin. In other words, when the sanitary napkin is filled with a cloth such as a sanitary napkin, an adhesive, or the like, and the physiological pants are pulled to a specific position on the body, it is necessary to grasp the upper part of the physiological pants. Pull up, but with this method of wearing 'physical pants, it has a certain degree of tightness with sanitary napkins. However, since the preference of the degree of closeness varies from person to person, those who want to make it more compatible, for example, read the so-called "By pulling up on the extension line of the micro-telescoping part in the center of the rear part, you can get higher "Compatibility", you can get the closeness you like. In this way, people who desire high-tightness can be induced to wear more easily. (2 3) The above indication is provided near the waistline portion above the micro-stretchable portion. According to the present invention, it is possible to make the sanitary napkin more conformable by pulling up the indicated portion. That is, the micro-stretching portion can be lifted by pulling the marked portion upward after grasping the flank portion mounted on the physiological pants. As the micro-stretching portion is lifted up, as described above, the sanitary napkin is strongly pressed upward from the femoral palate portion of the body, so that higher adhesion can be obtained. -21 · (18) 1233350 [Embodiment] Next, one embodiment of the physiological pants of the present invention will be described with reference to the drawings, but the present invention is not limited to this. The basic structure of the physiological pants of this embodiment is demonstrated. Fig. 1 is a front view showing the first embodiment of the physiological pants of the present invention which is not attached to the body, and the front body piece is connected to the back body piece in a state of being folded in half. Fig. 2 is a back face showing the state of being folded in half.

FIG. 6 is a partial plan view viewed from the bottom side of the lower part of the crotch, and FIG. 7 is a partial plan view showing other forms of the upper part of the sanitary napkin shown in FIG. Fig. 8 is a partial perspective view showing the inside of the lower part of the crotch, Fig. 9 is a partial side view of the lower part of the crotch, and Fig. 10 is a figure for explaining a micro-stretching part, a sanitary napkin upper lifting part and Fig. 11 is an explanatory diagram of the behavior of the fixed portion. Fig. 11 is a diagram for explaining the behavior of the physiological pants near the crotch when wearing the physiological pants of the present invention. Relationship between tensile strengthAs shown in FIGS. 1 to 4, the physiological pants 10 includes a front body piece 11 and a rear body piece 12, and a lower part 13 located between the front body piece 11 and the rear body piece 12, and The waistline portion 14 formed by the upper edge portion of the front body portion n and the upper edge portion of the rear body portion 12 and a pair of leg openings 15 formed on one of the lower sides of the front body portion n and the rear body portion 12 and at The lower part of the lower part 丨 3 is filled with raw-22- (19) 1233350 sanitary napkins with cloth I 6 (shown in Figure 8); near the waistline 1 4 there is a front body n and a back span. The waistline holding portion 1 7 'of the body piece 12 is provided with a micro-stretching portion 18 from the lower part of the hip 13 toward the waistline holding portion 17 in the central area of the rear body piece 12 from the other than the waistline holding portion 17 The micro-stretching portion 18 spans to the front body piece 11 and the excellent stretchable portion 19 'is provided over the entire area and is sewn on the approximate center line of the front body piece 11. Also, in the central area of the front body piece 11, outside the excellent stretchable portion 19, there are provided a sutured portion 1 3, a waist-retaining portion 17, and a fixing portion 20 on the excellent stretchable portion 19. The central area of the lower part 13 is provided with a tampon lifting part 21 from the micro-stretching part 18 toward the fixing part 20. A waist band 22 is provided on the waistline portion 14 at the upper ends of the front body panel 1 1 and the rear body panel 12, and a leg belt 23 is provided on the leg opening 15. In addition, when the physiological pants 10 are formed into a three-dimensional shape, the size ratio of the hip length La from the lower crotch portion 13 to the waistline portion 14 and the length Lb from the leg opening 15 to the shortest portion of the waistline 14 is relative to the size ratio. Hip length La is 100, and length Lb is 80-200. The excellent stretchable portion 19 can be formed, for example, from woven fabrics such as nylon fibers and polyurethane fibers, polyester fibers and polyurethane fibers, nylon fibers and polyester fibers, and polyurethane fibers. . In addition, even if it is not a combination of the above-mentioned fibers, as long as the drawing coefficient can be made below 10N, other fibers can be used. Further, the lower hip sheet 13 is composed of a lower hip sheet material 24. This lower hip sheet material 24 is sewn to the rear body sheet 12 side with the excellent stretched portion 19 and the lower hip sheet 13 side. The under hip cloth material 24 is the same as the excellent stretchable portion 19 by nylon fiber and polyurethane fiber, polyester fiber and polyurethane fiber, -23-1233350 (20) nylon fiber and polyester fiber and It is formed by woven fabrics such as polyurethane fibers that can be stretched freely. The waistband 22 provided on the waistline 14 and the legband 23 provided on the leg opening 15 are stretchable woven fabrics made of polyurethane fibers, synthetic rubber sheets, and natural rubber sheets. And so on. Here, the "longitudinal direction" means that the waistline 14, the lower part of the hips 13 and the leg openings 15 are used as the up and down direction (direction Y shown in Fig. 1). The meaning of the direction of taking off 'The so-called lateral direction refers to the direction perpendicular to the longitudinal direction (X direction shown in FIG. 1), which means the wide direction of the physiological pants. The waist circumference holding portion 17 is formed in a substantially V shape near the central portion of the front body portion 11 and the rear body portion 12 near the waist circumference portion 14 of the physiological pants 10, and is sewn to the front body portion 11 and the rear body portion 12 Excellent telescopic section 19. The waist I holding portion 1 7 ′ is a woven fabric having a tensile coefficient in the longitudinal direction that is stronger than a tensile coefficient in the lateral direction. The woven fabric is composed of nylon fiber and polyurethane fiber, polyester fiber and polyurethane. Ethyl fibers, nylon fibers, poly-fibers and polyurethane fibers. In addition, the waistband 22 provided at the upper end of the waistline portion 14 is a polyurethane belt, natural rubber belt, synthetic rubber belt, etc. of about 10 mm, and is sewed to the waistline holding portion 1 7 in a stretched state. . This waistline holding portion 17 is for dispersing the force of lifting the sanitary napkin upper lifting portion 21 from the micro-stretching portion 18 or the fixing portion 20, and the person who achieves the role of holding the waistline portion function can be stuck when wearing It is desirable that the waist is fixed and the extension in the longitudinal direction is suppressed. In addition, the number of stretches in the transverse direction is -24-1233350 (21), which is larger than the stretch factor in the transverse direction of the excellent stretchable portion 19, and it will be tightly tied to the waistline, because it can prevent the physiological pants 1 〇 The slide is more desirable. The above-mentioned micro-stretching portion 18 is located in the approximate central area of the rear body piece 12 and its upper end portion is at the central portion of the waistline holding portion 17 (the portion near the central tip of the V shape). The waistline holding portion 17 is sewn together, and the lower end portion is sewn together with the end portion 12 (the rear end portion of the lower chin portion 13) behind the lower body portion 13 and the middle portion is sewn to the excellent telescopic portion 19. It is formed and extends from the waistline holding portion 17 near the upper end of the waistline to the rear portion 13 of the lower crotch, and the end portion becomes thinner as it approaches the lower portion i3. The width of the thinner part is about 10 m to 30 m m, and preferably about 20 m m. The width of the part that is stitched with the waist circumference retaining section 7 is about 30 mm to 130 mm, and ideally it is about 60 mm. In addition, the micro-contraction portion 18 may extend to the waist portion 14 as well. Also, as described above, since the upper end portion of the micro-stretchable portion 18 and the stitching portion of the waist-retaining portion 17 are substantially V-shaped, the waist-retaining portion 17 of the woven fabric constituting the micro-stretchable portion 18 to the lower portion 1 The length of 3 is from the v-shaped central portion (the central apex portion of the v-shape) stitched with the waist-retaining portion 17 to the lower part of the chin (equivalent to Lc shown in FIG. 1) longer than the left and right ends. The length of the part (equivalent to Ld shown in Fig. 1) is still short. Therefore, the woven material from the V-shaped center to the lower part of the crotch will have a larger stretch rate when worn. In other words, the tensile force of the woven fabric becomes larger when worn. When the micro-stretching portion 18 is pulled upwards, the length from the v-shaped central portion to the lower portion 13 is shorter, so it will be stronger than the left and right ends by -25- (22) 1233350 Pull up, the central part will not relax, and it can express the force of lifting the sanitary napkin 25. Regarding the relationship between these lengths', this physiological supplement 10 was worn on a dummy, and the length and elongation before and after wearing were measured, and the results are shown in Table 1. As shown in Table 1, the length of the V-shaped central portion is shorter before wearing, and the stretch rate is larger when wearing. [Table 1] Length and elongation of the woven material of the micro-stretched portion and the fixed portion The left and right end portions of the V-shaped center of the V-shaped portion of the V-shaped fixed portion of the micro-stretched portion (Lc) (Ld) Length (Lc) (Ld) before wearing C m 13. 0 14. 5 7. 5 12. 0 Length c m 16. 0 17. 0 10. 4 15. 0 Elongation% 23. 1 17. 2 38. 7 25. 0 1) V-shaped central portion (Lc): Length from the central apex of the V-shape to the lower part of the cymbal 2) Left and right end (Ld): The central apex of the V-shape from the vertex of the left and right ends to the lower part of the 胯The length of the micro-stretching portion 18 can be, for example, nylon fiber and / or polyester fiber, nylon fiber and polyurethane fiber, polyester fiber and polyurethane fiber, nylon fiber and polyester fiber and polyurethane It is composed of a woven cloth such as ethyl acetate fiber. As the woven fabric material constituting the micro-stretching portion 18, a so-called stretchable member which does not use polyurethane fiber or the like in the longitudinal direction may be used to constitute -26- (23) 1233350, and the structure may be changed by knitting. For those woven materials that are somewhat stretchable, but the component itself is not stretchable, the tensile coefficient of the longitudinal direction of the woven material is greater than the tensile coefficient of the longitudinal direction of the excellent stretchable portion 19, that is, constitutes micro-striction The woven material of the part 18 is less likely to be extended than the good stretchable part 19. Therefore, since the excellent stretchable portion 19 covering the buttocks or the abdomen is composed of a woven fabric that can stretch freely in the longitudinal direction and the transverse direction, it will follow the deformation of the body caused by the movement of the body. The micro-stretching portion 18 in the approximate central region of the rear body piece 12 has a longitudinal stretch coefficient larger than that of the excellent stretchable portion 19, so it is not easily affected by the movement of the excellent stretchable portion 19. The stretchability of the micro-stretchable portion 18 is preferably about 10N to 60N, and more preferably about 20N to 50N. If the stretching coefficient is less than 1 ON, the force for lifting the sanitary napkin 25 is insufficient. If it is more than 60N, the sanitary napkin 25 will become too bite into the gap of the body. Moreover, in the case where the micro-stretchable portion 18 does not expand or contract at all, the force of lifting the physiological pants 10 also directly exerts the function of lifting the physiological sanitary napkin 25, but it is easy to cause the physiological sanitary napkin 25 to be attached to it. Lifting force above is not good because the sanitary napkin 2 5 is biting too much into the body, which will cause discomfort or pain. On the other hand, if the stretch is too large, when the physiological pants 10 are lifted up, it cannot effectively exert the effect of lifting the sanitary napkin 25 due to the large stretch. On the other hand, the stretch coefficient of the excellent stretchable portion 19 is 1 ON or less, and the ideal stretch coefficient is about 2N to 3N when stretched 10 to 30%. Specifically, the tensile load factor when stretched by about 20% when worn is between 0 · 4 ~ 0. 6N or so, it will be tightly tied to the body in a gentle fit. -27- 1233350 (24) The "stretching coefficient of the stomach and buds" mentioned here means the stretching coefficient when worn on a dummy of size M. In addition, the micro-stretching portion 18 may be constituted by those having the same elongation, or as shown in FIG. 5, the elongation may be gradually decreased from the left and right end portions to the central portion, or may be changed. Continuous changer. Fig. 5 is an enlarged view of a part of the micro-stretched portion 18, which shows the micro-stretched portion 18 in a mode, and the stretch rate is gradually changed from the left and right end portions 18a to the center portion 18b. The relationship between the stretch ratio and tensile strength of the micro-stretching portion 18 of the physiological pant 10 of the present invention is compared with the conventional physiological pant and is shown in Fig. 12 for reference. As shown in FIG. 12, the elastic member provided in the approximate central area of the body behind the conventional physiological pants extends 30% when worn. When the physiological pants are subjected to the so-called P 1 tensile load, the physiological characteristics of the present invention In the case of the pants 10, the same stretch of 30% can withstand the so-called tensile load of P2. The physiological pants 10 of the present invention have greater tensile strength than conventional physiological pants. That is, it has the characteristics of P2> P1. When the physiological pants 10 of the present invention are worn, even if they are only stretched by 10%, the physiological pants 10 of the present invention can withstand a tensile strength P3 which is stronger than that of the conventional physiological pants P1. That is, compared with conventional physiological pants, even if the elongation is small, the tensile strength is large enough, and it can effectively exert its effect as a force for stretching the lower part of the diaphragm. Therefore, the force of lifting the night-use sanitary napkin 25 will increase, and it will be more fit to the crotch of the body. In addition, the fixing portion 20 of the physiological pants 10 is formed of a strong mesh, and is located outside the excellent stretchable portion 19 in the approximately central area of the front panel 11, and its upper end portion is located in the central portion of the waist-retaining portion 17 (sandwiched) In the V shape, -28- (25) 1233350 (near the central apex) is sewn simultaneously with the waist-retaining portion 17 and the excellent telescopic portion 19, and its lower end portion is located on the n side of the body before the lower part of the trunk The end part (the front part before the lower part of the chin 13) is sutured at the same time with the sanitary napkin upper part 21 and the tampon cloth 16 of the lower chin 13 and the excellent stretchable part 19, and the middle part is sutured于 Excellent telescopic section 1 9. And, as the waistline holding portion 17 is closer to the lower crotch portion 13 side, the width becomes narrower, and it is sewn to the sanitary napkin upper lifting portion 2 formed in the approximately central area of the lower crotch portion 13] and connected together . The width of the portion connected to the upper lifting portion 21 of the sanitary napkin is approximately the same as the width of the front end portion of the front body 11 of the upper portion of the sanitary napkin. Further, the upper end portion which is joined together with the waist-retaining portion 17 is substantially V-shaped, and its width is about 60 mm to 150 mm, and preferably about 80 mm to 120 mm. As described above, the upper end side of the fixing portion 20 and the waist-retaining portion 17 are sewn into a substantially V-shape, which is similar to the case of the micro-stretching portion 18. When the fixing portion 20 is pulled upwards toward the upper side, The length from the V-shaped central portion (V-shaped central apex portion) to the lower part 13 (Lc shown in Fig. 1) is shorter than the length of the left and right ends (Ld shown in Fig. 1). , So it will be pulled upwards by a stronger force than the left and right ends (see table 1). Therefore, the central portion does not become slack, and the force of lifting a sanitary napkin can be expressed. The strong woven mesh constituting the fixed portion 20 is a woven material composed of nylon fibers and polyurethane fibers of 100 dtex or more. The longitudinal direction tensile coefficient is higher than that of the excellent stretchable portion 19 in the longitudinal direction. It is also large, that is, the woven material of the strong woven mesh constituting the fixed portion 20 is more difficult to extend than the good stretchable portion 19. The tensile strength of the fixing portion in the longitudinal direction is -29-1233350 (26), and the tensile coefficient is about 10N ~ 30N, more preferably about 15N ~ 30N. The type and mixing ratio of the fibers constituting the strong mesh of the fixed portion 20 are not limited to these, and may be appropriately selected as long as the above-mentioned effect can be obtained. In addition, the above-mentioned sanitary napkin upper lifting portion 21 is a substantially central area of the lower crotch portion 1 3 which is composed of the hip lower cloth material 2 4 which is the same material as the excellent stretchable portion 19, as shown in FIG. The end portion is sewn together with the end portion of the crotch portion side of the micro-stretching portion 18 provided in the approximately central area of the back body piece 12, and the other end portion is fixed with the approximately central area provided in the front body piece Π. The end of the femoral palate side of part 20 is sutured together, and the middle part is formed by sewing with the under hip cloth material 24, which extends from the vicinity of the part that blocks the pubic bone to the vicinity of the anus when worn, and from the front body piece The closer the 1 1 front end portion is to the rear body piece 1 2 the narrower the rear end portion becomes. The width of the upper part of the sanitary napkin 2 1 is about 50 mm to 80 mm, ideally about 70 mm. The width of the narrow part is about Ø 3 to 30 mm, ideally 2 About 0 mm. The sanitary napkin upper lifting portion 2 1 ′ is the same as the micro-stretching portion 18 using nylon fibers and / or polyester fibers, nylon fibers and polyurethane fibers, polyester fibers and polyurethane fibers, and nylon fibers. Woven fabrics such as polyester fibers and polyurethane fibers are made of woven fabrics that are somewhat stretchable due to changes in the weaving structure, but the members themselves are not stretchable. It is smaller than the stretch factor in the longitudinal direction of the micro-stretched portion 18, that is, the woven fabric material constituting the sanitary napkin upper lifting portion 21 is more easily extended than the micro-stretched portion 18. • 30-1233350 (27) The stretchability of the upper lifting part 21 of the sanitary napkin is preferably about 5N ~ 30N, and more preferably about 10N ~ 25N. If the elongation factor is less than 5 N, it becomes easy to extend, which is insufficient for lifting the central portion of the sanitary napkin 2 5. If it is greater than 3 0N, the stretchability becomes higher than that of the micro-stretchable portion 18, and it is difficult to exert the function of bringing the central portion of the sanitary napkin 25 onto the body gap. In addition, as shown in FIG. 7, the width of the upper portion of the sanitary napkin 21 is taken as the maximum, and the width of the upper portion of the sanitary napkin may be gradually narrowed as it approaches the middle area. It gradually widens from the middle area toward the portion to be sewn on the micro-stretched portion 18. At this time, the width of the sanitary napkin upper lifting portion 21 being sewn to the portion of the micro-stretching portion 18 is narrower than that of the portion being sewn to the fixing portion 20. On the inner side of the lower crotch 13 as shown in FIG. 8, the sanitary napkin is attached with a cloth 16 by sewing the front end portion 11 and the rear end portion 12 and the rear end portion on the lower crotch portion 13 and Settings. The sanitary cotton cloth 16 is a tarpaulin formed by laminating a polyester woven circular woven moss woven fabric and processing it with polyurethane, and a film surface for protecting the laminated surface The left and right ends of the polyester knitted fabric are stitched to make the fabric and film integrated. The length L2 of the sanitary napkin 16 is the same as or longer than the length L1 of the lower crotch portion 13, as shown in FIG. Specifically, the length L1 of the lower crotch portion 13 is about 140 mm to 190 mm, preferably about 160 mm. In addition, the length L2 of the sanitary napkin containing the cloth 16 is about 140 m m to 220 m m, and preferably about 200 m m. In addition, the excellent stretchable portion 19 of the physiological pants 10 is made of black semi-free -31-(28) 1233350 light woven fabric, waist circumference holding portion 1, 7, micro-stretching portion 1, 8, sanitary napkin upper lifting portion 2 1 is brown There is light weaving. The strong woven mesh constituting the fixing portion 20 may be formed of a different color from the woven fabric of the excellent stretchable portion 19. In this way, the excellent stretchable portion 19 and waist circumference retaining portion 17, the micro-stretchable portion 18, the sanitary napkin lifting portion 21, and the fixing portion 20 are different colors, or even the same color can be composed of fibers that change the amount of titanium oxide. It is desirable to make the reflection of light different, so that the appearance of the upper lifting part is conspicuous. Next, when wearing the physiological pants 10 of the present invention, the behavior of the micro-stretching portion 18, the sanitary napkin lifting portion 21, and the fixing portion 20 provided in the physiological pants 10 will be described based on FIGS. 10 and 11. . FIG. 10 is an explanatory diagram for explaining the behavior of the micro-stretching part, the tampon lifting part, and the fixing part of the crotch portion of the body when the physiological pants of the present invention are worn, showing the crotch portion of the body. Section. Fig. 11 is a diagram for explaining the behavior of the physiological pants near the crotch when wearing the physiological pants, and shows a cross section of the crotch portion. When wearing physiological pants 10, as shown in Fig. 10, it will be subjected to the pull force T! Of the micro-stretching portion 18, and the upper portion of the sanitary napkin 21 will be based on the base point A (for the fixed portion 20 and the lower part). The stitching part of 1 3 is near the pubic bone that is blocking the body) as a base point, and the force T3 that pulls toward the back side of the body by burying the body gap will work. On the other hand, the force T3 of the upper lifting part 21 of the lifting sanitary napkin will act as an upward force T4 in the central part of the sanitary napkin 25. In addition, the width of the upper part 21 of the tampon on the side of the base point A is about 70 mm, from the mouth to the perineum and the vicinity of the anus (spanning to the base point of the suture portion of the micro-stretching portion 18 and the lower portion 13). B) It will gradually become thinner, with a wide width of -32 · (29) 1233350 to about 20 mm. Thereby, since the width on the side of the base point a is wide, the base point A is stabilized 'and the balance near the mouth can be maintained. If the width on the side of the base point A is narrowed to about 20 mm, the center may shift at the time of wearing, which is not desirable due to the possibility of shifting from the center of the mouth. As shown in FIG. 11, the width of the sanitary napkin upper lifting portion 21 is narrowed to about 20 mm near the mouth, and the tensile coefficient of the sanitary napkin upper lifting portion 21 is smaller than that of the surrounding woven fabric. The material is still high, so it exerts its function as the upward force T4 as the force lifting the central portion of the sanitary napkin 25 stretched by a stronger force upward. In addition, as shown in FIG. 10, the micro-stretching portion 18 exerts a pull force T! Toward the upper side of the rear body piece, and exerts the tampon lifting portion 21 to stretch in the rear direction (back body piece side). The role. Therefore, at the base point A, a force to be displaced in the rear direction is generated, but if the base point A is displaced toward the rear, the micro-stretching portion 18 and the sanitary napkin lifting portion 21 are used to make the sanitary napkin 2 5 The force of synergy is not easy to play. That is, the entire body is displaced toward the rear, and no force is applied to fit the sanitary napkin 2 5 to the body. In order to prevent this from happening, it is desirable to fix the base point A as much as possible, but on the other hand, the fixing portion 20 of the front body 11 will exert a force as a fixed base point A. That is, by suturing the strong mesh constituting the fixing portion 20 to the outer side of the excellent stretchable portion 19 of the physiological pants 10, the force T2 of the front body piece 11 to be extended in the longitudinal direction can be suppressed. In this way, since the extension of the front body piece 11 can be suppressed by the fixing portion 20, the base point A will not be stretched by the influence of the micro-stretching portion 18 and the tampon lifting portion 21 because -33 -I233350 (30) was fixed. The longitudinal stretching coefficient of the woven fabric material of the strong woven mesh constituting the fixed portion 20 is preferably about 10N to 30N. This is because the abdomen blocked by the front body piece 11 is a part that will be greatly deformed due to body movements. Therefore, if it is a completely non-stretchable woven material, the waistline at the upper end of the front body piece 1 1 will slide down. There is a risk of compromising compatibility. Here, the base point A is a suture portion of the fixed portion 20 and the lower iliac crest 13, which is equivalent to a place close to the pubic bone of the body. The base point B is a suture portion of the micro-elastic portion 18 and the lower iliac crest 13 Closer to the back than the anus! 2 sides, which is equivalent to the vicinity of 1 500 ~ 2 0 0 m η from the pubic bone toward the rear (the side of the back body 12). Next, a method for measuring the stretchability of various parts of the physiological pants (micro-stretchable portion, tampon lifting portion, fixed portion, and excellent stretchable portion) will be described. < Measurement of the micro-stretching portion > The end portion of the body j 2 side (the rear portion of the lower portion 13) of the physiological pants 10, the micro-stretching portion 18, the lower portion 13 and the suture portion, and The stitching part is in the direction of the waistline 14 and the chuck is at a distance of 00 mm. The chuck is clamped by a chuck (the size of the clamping surface is 35 mm x 25 mm rectangular). Fortunately, it was stretched by a tensile tester at 100 mm / The micro-stretched portion was stretched to 50% 'at a stretching speed of min, and a tensile load of 10% per stretch was measured. 3, Chongsheng cotton lifting and lifting of the sanitary pads 21 of the physiological pants 10 and the stitching portion of the front body piece n and the direction of the backing piece 12 from the stitching portion, the chucks are spaced to = • 34-1233350 (31) 150 The position of mm is clamped by a chuck (the size of the clamping surface is a rectangular shape of 35 mmx25 mm), and the tensile tester is used to stretch to 50% at a tensile speed of 100 mm / m, and measured. Tensile load per 10% of tensile load. < Measurement of the fixing part > The end part (the front part of the lower part of the front part 13) of the front part 11 and the sewing part of the front part 11 of the body part 1 (the front part of the front part 13) and the fixing part 20 of the physiological pants 10 and the lower part 13 It is clamped at a position where the chuck interval is 80 mm (the size of the clamping surface is a rectangular shape of 35 mm x 25 mm) from the suture to the waist circumference 14 direction, and it is clamped at 100 mm by a tensile tester. The tensile speed of / min was used to stretch the fixed portion 20 to 50%, and the tensile load per 10% of the stretch was measured. < Measurement of good stretchable part > Cut the good stretchable part 19 of the physiological pants 10 into a length of 130 mmx a width of 25 mm, and a chuck with a chuck spacing of 100 mm (the size of the clamping surface is 35 mmx25) A rectangular shape of mm) is clamped, and the excellent stretchable portion 19 is stretched to 50% by a tensile tester at a stretching speed of 100 mm / mi η, and the stretch per 10% of the stretch is measured. Load. The tensile coefficient is the value obtained by dividing the tensile load measured by the above method by the elongation at that time. For example, the tensile coefficient when the tensile load is 20% and the tensile load is 10N is 10N / 0, 2 = 50N.
