Description
本發明係關於吸收性物品，特別是關於可抑制體液的逆流之吸收性物品。 The present invention relates to absorbent articles, and more particularly to absorbent articles which inhibit back flow of body fluids.
在專利文獻1中，記載有吸收性物品，其具備透液性的表面薄片、不透液性的裏面薄片、及配置於表面薄片與裏面薄片之間的吸收體，在吸收體與表面薄片之間具有第2薄片，且表片薄片具有被朝厚度方向壓榨之壓榨部。 Patent Document 1 describes an absorbent article comprising a liquid permeable surface sheet, a liquid impermeable back sheet, and an absorbent body disposed between the surface sheet and the back sheet, in the absorbent body and the surface sheet. There is a second sheet therebetween, and the sheet sheet has a press portion pressed in the thickness direction.
第2薄片係由開孔狀不織布或網眼狀薄膜所構成，用來使通過表面薄片的體液迅速地移行至吸收體者。在表面薄片形成有壓榨部之壓榨區域係密度較未形成有壓榨部之非壓榨區域高，可將體液迅速地吸入(吸收)至表面薄片內。被吸入到表面薄片的體液經由第2薄片移行至吸收體。當體液一旦移行至吸收體時，即使在吸收體自表面薄片側被按壓之情況，也不易返回至表面薄片側，能夠抑制體液的逆流。 The second sheet is composed of an open-celled nonwoven fabric or a mesh-like film for rapidly moving body fluid passing through the surface sheet to the absorbent body. The press zone having the press section formed on the surface sheet has a higher density than the non-pressing zone where the press section is not formed, and the body fluid can be quickly sucked (absorbed) into the surface sheet. The body fluid sucked into the surface sheet is transferred to the absorber via the second sheet. When the body fluid migrates to the absorber, even when the absorber is pressed from the surface sheet side, it is difficult to return to the surface sheet side, and the backflow of the body fluid can be suppressed.

但，上述的吸收性物品存在有以下的問題。 However, the above absorbent article has the following problems.
表面薄片的壓榨部係呈規則性地形成於表面薄片的全 體範圍。因此，表面薄片全體的剛性均等地變高。當表面薄片全體的剛性變高時，吸收性物品不易追隨穿用者的動作變形，會有穿用時的不舒適感增加之虞。 The press section of the surface sheet is regularly formed on the surface sheet Body range. Therefore, the rigidity of the entire surface sheet is uniformly increased. When the rigidity of the entire surface sheet is increased, the absorbent article is less likely to follow the movement of the wearer, and the discomfort during wearing may increase.
又，近年，為了提昇穿用感，期望薄型之吸收性物品。但，薄型的吸收性物品係吸收體的厚度構成為較薄，造成會有體液的吸入性降低之虞產生。 Moreover, in recent years, in order to enhance the wearing feeling, a thin absorbent article is desired. However, in the thin absorbent article, the thickness of the absorbent body is made thin, and the inhalation of the body fluid is lowered.
因此，本發明係有鑑於上述課題而開發完成之發明，其目的係在於提供既可壓低吸收體的厚度同時抑制體液的逆流，又可減低穿用時之不舒適感的吸收性物品。 Accordingly, the present invention has been made in view of the above problems, and an object of the invention is to provide an absorbent article which can reduce the thickness of the absorbent body while suppressing the backflow of the body fluid and reducing the discomfort during wearing.
為了解決上述課題，本發明之吸收性物品，係具備透液性的表面薄片、不透液性的裏面薄片、及配置於前述表面薄片與前述裏面薄片之間的吸收體，其特徵為，在前述吸收體形成有朝厚度方向被壓榨之吸收體壓榨部，而在前述表面薄片間歇地形成有朝厚度方向被壓榨之複數個表面薄片壓榨部，前述吸收體係具有藉由前述吸收體壓榨部所區劃之小區域，在前述小區域分別配置有高吸收性聚合物粒子，在前述厚度方向上，前述表面薄片壓榨部分別重疊於前述小區域，前述小區域係具備第1小區域與第2小區域，重疊於前述第1小區域的前述表面薄片壓榨部的配置圖案與重疊於前述第2區域的前述表面薄片壓榨部的配置圖案係構成為不相同。 In order to solve the above problems, the absorbent article of the present invention comprises a liquid permeable surface sheet, a liquid impermeable back sheet, and an absorber disposed between the surface sheet and the back sheet, wherein The absorbent body is formed with an absorbent body press portion pressed in a thickness direction, and a plurality of surface sheet press portions pressed in a thickness direction are intermittently formed on the surface sheet, and the absorbent system has a press portion by the absorbent body In the small area, the superabsorbent polymer particles are disposed in the small area, and the surface sheet press portion overlaps the small area in the thickness direction, and the small area includes the first small area and the second small area. In the region, the arrangement pattern of the surface sheet press portion overlapping the first small region and the arrangement pattern of the surface sheet press portion superposed on the second region are different.
又，本發明之吸收性物品，係具備透液性的表面薄片、不透液性的裏面薄片、及配置於前述表面薄片與前述裏面薄片之間的吸收體，其特徵為，在前述吸收體形成有朝 厚度方向被壓榨之吸收體壓榨部，而在前述表面薄片間歇地形成有朝厚度方向被壓榨之複數個表面薄片壓榨部，前述吸收體係具有藉由前述吸收體壓榨部所區劃之小區域，在前述小區域分別配置有高吸收性聚合物粒子，在前述厚度方向上，前述表面薄片壓榨部分別重疊於前述小區域，前述吸收體壓榨部係經由前述表面薄片可視認。 Further, the absorbent article of the present invention is provided with a liquid permeable surface sheet, a liquid impermeable back sheet, and an absorbent body disposed between the surface sheet and the back sheet, and is characterized in that the absorbent body Formed with The absorbing body press portion is pressed in the thickness direction, and the surface sheet is intermittently formed with a plurality of surface sheet press portions pressed in the thickness direction, and the absorbing system has a small region partitioned by the absorbing body press portion. Each of the small regions is provided with superabsorbent polymer particles, and the surface sheet press portion is superposed on the small region in the thickness direction, and the absorber press portion is visible through the surface sheet.
本發明之吸收性物品係當因穿用者的動作所產生之外力作用時，能夠以表面薄片壓榨部、吸收體壓榨部等作為起點，使未形成有表面薄片壓榨部、吸收體壓榨部等之部分變形。由於表面薄片壓榨部的配置圖案與吸收體壓榨部的配置圖案不同，故，藉由表面薄片壓榨部與吸收體壓榨部之組合，能夠在吸收體物品全體，不規則地配置被壓榨之區域。比起表面薄片全體被均等地壓榨之吸收性物品，亦可追隨不規則的動作而容易變形，能夠減低穿用時的不舒適感。 In the absorbent article of the present invention, when a force acts by the action of the wearer, the surface sheet press portion, the absorber press portion, or the like can be used as a starting point, and the surface sheet press portion, the absorber press portion, and the like are not formed. Part of the deformation. Since the arrangement pattern of the surface sheet press portion is different from the arrangement pattern of the absorber press portion, the combination of the surface sheet press portion and the absorber press portion can irregularly arrange the pressed region in the entire absorbent article. The absorbent article which is uniformly pressed against the entire surface sheet can be easily deformed following irregular movements, and the feeling of discomfort during wearing can be reduced.
在表面薄片，間歇地形成有複數個表面薄片壓榨部，附著於表面薄片上的體液會藉由表面薄片壓榨部迅速地吸入至表面薄片內。在表面薄片壓榨部的下方，配置著形成有吸收體壓榨部的區域或未形成有吸收體壓榨部的區域。又，在未形成有吸收體壓榨部的區域配置於表面薄片壓榨部的下方之部分，能夠將從表面薄片吸入至吸收體的體液保持在未形成有吸收體壓榨部的區域。又，一旦移行至吸 收體的體液會被高吸收性聚合物所保持而不會移行至穿用者側。若依據如此所構成之吸收性物品，既可抑制吸收體的厚度，又可提高體液的吸入(吸收)性，並且可防止體液逆流。 In the surface sheet, a plurality of surface sheet press portions are intermittently formed, and the body fluid adhering to the surface sheet is quickly sucked into the surface sheet by the surface sheet press portion. Below the surface sheet press portion, a region where the absorber press portion is formed or a region where the absorber press portion is not formed is disposed. Further, in a region where the absorber press portion is not formed, the portion below the surface sheet press portion is disposed, and the body fluid sucked from the surface sheet to the absorber can be held in a region where the absorber press portion is not formed. Again, once you move to suck The body fluid of the body is held by the superabsorbent polymer without moving to the wearer side. According to the absorbent article thus constituted, the thickness of the absorbent body can be suppressed, the suction (absorption) of the body fluid can be improved, and the backflow of the body fluid can be prevented.
參照圖1及圖2，說明關於實施形態之吸收性物品1。圖1係吸收性物品的平面圖，圖2係吸收性物品之背面圖。本實施形態之吸收性物品1例如為護墊。 The absorbent article 1 according to the embodiment will be described with reference to Figs. 1 and 2 . Figure 1 is a plan view of an absorbent article, and Figure 2 is a rear view of the absorbent article. The absorbent article 1 of the present embodiment is, for example, a pad.
吸收性物品1係具有：抵接於穿用者的肌膚之表面薄片10；不會使體液透過的具不透液性之裏面薄片20；及吸收體30。吸收體30係配設於表面薄片10與裏面薄片20之間。因此，吸收體30係如圖1及圖2中的虛線所示。吸收體30係配設於吸收性物品1的長度方向L及寬度方向W之中央部分。吸收性物品1係具備有在寬度方向W上設置於表面薄片10的外側之側薄片41、42。 The absorbent article 1 has a surface sheet 10 that abuts against the wearer's skin, a liquid-impermeable back sheet 20 that does not allow body fluid to pass through, and an absorbent body 30. The absorber 30 is disposed between the surface sheet 10 and the back sheet 20. Therefore, the absorber 30 is shown by a broken line in FIGS. 1 and 2. The absorber 30 is disposed in a central portion of the absorbent article 1 in the longitudinal direction L and the width direction W. The absorbent article 1 is provided with side sheets 41 and 42 which are provided on the outer side of the surface sheet 10 in the width direction W.
表面薄片10係為可使體液等的液體透過之具透液性的薄片。表面薄片10係至少覆蓋吸收體30的表面。表面薄片10，若為不織布、織布、有孔塑膠薄片、網狀薄片等可使液體透過的構造之薄片狀材料則未特別限定。作為織布、不織布的材料，天然纖維、化學纖維等皆可使用。表面薄片10係具有：配置於穿用者側之頂面薄片11；和配置於頂面薄片的下方(裏面薄片側)之第2薄片12。頂面薄片11與第2薄片12係藉由熱熔膠接著劑所接合著。 The surface sheet 10 is a liquid-permeable sheet which can permeate a liquid such as a body fluid. The surface sheet 10 covers at least the surface of the absorber 30. The surface sheet 10 is not particularly limited as long as it is a sheet-like material having a structure such that a nonwoven fabric, a woven fabric, a perforated plastic sheet, or a mesh sheet can transmit liquid. As a material for woven or non-woven fabrics, natural fibers, chemical fibers, and the like can be used. The top sheet 10 has a top sheet 11 disposed on the wearer side and a second sheet 12 disposed on the lower side (back sheet side) of the top sheet. The top sheet 11 and the second sheet 12 are joined by a hot melt adhesive.
裏面薄片20係具有與表面薄片10的長度大致相同的長度。裏面薄片20係使用以聚乙烯薄片、聚丙烯等為主體之層積薄不織布，通氣性樹脂薄膜，將通氣性樹脂薄膜接合於紡黏、水針不織布等之薄片等。裏面薄片20之材料係具有穿用時不會產生不舒適感程度之柔軟性者為佳。裏面薄片20，理想為具不透液性及透濕性，例如能夠藉由將在聚乙烯、聚丙烯等的烯烴系樹脂融熔拌合有無機填充劑者進行延伸處理之為多孔性薄片來構成為佳。 The inner sheet 20 has a length substantially the same as the length of the surface sheet 10. In the inner sheet 20, a thin laminated nonwoven fabric mainly composed of a polyethylene sheet, polypropylene, or the like is used, and an air-permeable resin film is bonded to a sheet such as a spunbond or a water needle nonwoven fabric. The material of the inner sheet 20 is preferably one which does not cause discomfort when worn. The inner sheet 20 is preferably liquid-impermeable and moisture-permeable. For example, it can be expanded into a porous sheet by melting an olefin-based resin such as polyethylene or polypropylene and mixing the inorganic filler. The composition is better.
吸收體30係以配置於表面薄片10側的緩衝材和吸收體材料來構成。吸收體材料係具有可吸收尿液等的液體並予以保持之功能。例如可舉出由熱風不織布與高吸收聚合物所構成之吸收體材料。作為高吸收聚合物(SAP)，例如可舉出澱粉系、丙烯酸系、胺基酸系的粒子狀或纖維狀聚合物。作為液體吸收物質僅由不含紙漿之聚合物所構成。本實施形態之吸收體30係以由熱可塑性纖維所構成之基量25g/m2的熱風不織布包住高吸收性聚合物來形成的。 The absorber 30 is configured by a cushioning material and an absorber material disposed on the surface sheet 10 side. The absorbent body material has a function of absorbing a liquid such as urine and holding it. For example, an absorbent material composed of a hot air non-woven fabric and a superabsorbent polymer can be cited. Examples of the superabsorbent polymer (SAP) include starch-based, acrylic-based, and amino acid-based particulate or fibrous polymers. As the liquid absorbing material, it consists only of a polymer which does not contain pulp. The absorber 30 of the present embodiment is formed by encapsulating a superabsorbent polymer with a hot air non-woven fabric having a basis weight of 25 g/m 2 composed of thermoplastic fibers.
側薄片41、42係配設於表面薄片10的兩側。側薄片41、42的材料可由與表面薄片10相同的材料來選擇。但，為了防止體液越過側薄片41、42而朝吸收性物品1外側流動，具有疏水性或撥水性為佳。側薄片41、42覆蓋吸收體30的側緣。 The side sheets 41 and 42 are disposed on both sides of the surface sheet 10. The material of the side sheets 41, 42 can be selected from the same material as the surface sheet 10. However, in order to prevent the body fluid from flowing over the side sheets 41 and 42 toward the outside of the absorbent article 1, it is preferred to have hydrophobicity or water repellency. The side sheets 41, 42 cover the side edges of the absorbent body 30.
在吸收性物品1，表面薄片10、側薄片41、42、及裏面薄片20的周緣被接合，而內封吸收體30。作為表面薄片10與裏面薄片20之接合方法，可採用熱壓花加工、超 音波、或熱熔膠接著劑的其中一種，或組合複數種。 In the absorbent article 1, the peripheral edges of the surface sheet 10, the side sheets 41, 42, and the back sheet 20 are joined to enclose the absorbent body 30. As a method of joining the surface sheet 10 and the inner sheet 20, hot embossing processing can be used. One of sound waves, or hot melt adhesives, or a combination of plural.
在裏面薄片20，於與內褲接觸的表面，在複數個區域塗佈有黏合材50(參照圖2)。黏合材50係在吸收體的裏面側，沿著長度方向L間歇地配置著。在使用前的狀態，黏合材50係接觸於剝離薄片(未圖示)。剝離薄片係防止黏合材50在使用前劣化。又，當使用時，使用者剝離該剝離薄片。 In the inner sheet 20, an adhesive material 50 is applied to a plurality of regions on the surface in contact with the undergarment (see Fig. 2). The adhesive 50 is attached to the back side of the absorber, and is intermittently arranged along the longitudinal direction L. In the state before use, the adhesive 50 is in contact with a release sheet (not shown). The release sheet prevents the adhesive 50 from deteriorating before use. Also, when used, the user peels off the release sheet.
再者，在不具有剝離薄片之吸收性物品，亦可構成為藉由將吸收性物品個別地包裝之包裝薄片來防止黏合材在使用前劣化。在黏合材與包裝薄片接觸之情況，在包裝薄片的表面，實施不會使黏合材的黏合力降低而可將黏合材作成為可剝離之處理為佳。 Further, in the absorbent article which does not have a release sheet, it is also possible to prevent the adhesive material from being deteriorated before use by packaging the packaging sheet in which the absorbent article is individually packaged. When the adhesive material is in contact with the packaging sheet, it is preferable to carry out the treatment of peeling the adhesive material on the surface of the packaging sheet without lowering the adhesive force of the adhesive material.
圖3係吸收體30的平面圖。在吸收體30，形成有將吸收體30朝厚度方向壓榨之吸收體壓榨部90。吸收體壓榨部90係具備有：形成於吸收體30的長度方向L之兩端部的第1吸收體壓榨部91；及格子狀的第2吸收體壓榨部92。第1吸收體壓榨部91係呈小四角形，間歇地形成有複數個。在以不織布包住高吸收性聚合物並折疊之狀態下，藉由形成第1吸收體壓榨部91，能夠將吸收體30的兩端部予以接合，而將高吸收性聚合物收容於不織布內部。 3 is a plan view of the absorber 30. In the absorber 30, the absorber press part 90 which presses the absorber 30 in the thickness direction is formed. The absorber press portion 90 includes a first absorber press portion 91 formed at both end portions of the absorber 30 in the longitudinal direction L, and a lattice-shaped second absorber press portion 92. The first absorber press portion 91 has a small square shape, and a plurality of portions are intermittently formed. By forming the first absorber pressing portion 91 in a state in which the superabsorbent polymer is wrapped in a non-woven fabric and folded, the both ends of the absorber 30 can be joined, and the superabsorbent polymer can be accommodated in the nonwoven fabric. .
第2吸收體壓榨部92係間歇地配置於延伸在長度方向L之第1直線C1上及第2直線C2上。此第1直線C1與第2直線C2係交叉著，配置成格子狀。再者，第1直線C1上及第2直線C2係在圖3中分別以一點鏈線顯示。 在吸收體30，形成有藉由第2吸收體壓榨部92所區劃之小區域31。在小區域31各自配置有高吸收性聚合物粒子。 The second absorber press portion 92 is intermittently disposed on the first straight line C1 and the second straight line C2 extending in the longitudinal direction L. The first straight line C1 and the second straight line C2 are intersected and arranged in a lattice shape. Further, the first straight line C1 and the second straight line C2 are respectively shown by a one-dot chain line in FIG. 3 . In the absorber 30, a small region 31 partitioned by the second absorber press portion 92 is formed. Superabsorbent polymer particles are disposed in each of the small regions 31.
再者，第1直線C1與第2直線C2，可為沿著長度方向L之直線，亦可為對長度方向L傾斜之直線。例如，亦可為與長度方向L交叉之角度(銳角側)為45度以下的直線，亦可為與寬度方向W交叉之角度(銳角側)為未滿45度的直線。 Further, the first straight line C1 and the second straight line C2 may be straight lines along the longitudinal direction L or straight lines inclined to the longitudinal direction L. For example, a straight line intersecting the longitudinal direction L (an acute angle side) may be a straight line of 45 degrees or less, or an angle intersecting the width direction W (an acute angle side) may be a straight line of less than 45 degrees.
吸收性物品係在被穿用者穿用著之狀態下配置於胯下。當穿用者移動腳時，每次單腳單腳移動。因此，配置於穿用者的胯下之吸收性物品上，會有朝斜向扭轉之方向的外力作用。此時，例如第2吸收體壓榨部92為沿著寬度方向W所形成之吸收體30會不易追隨腳的動作而傾斜變形。但，由於第2吸收體壓榨部92係對長度方向L傾斜，故，當因穿用者的雙腳的動作而朝斜向扭轉時，容易追隨腳的動作加以變形。 The absorbent article is placed under the armpit while being worn by the wearer. When the wearer moves the foot, it moves one foot at a time. Therefore, the absorbent article placed under the armpit of the wearer has an external force acting in the direction of oblique twisting. At this time, for example, the second absorber pressing portion 92 is inclined so that the absorber 30 formed along the width direction W does not easily follow the movement of the foot. However, since the second absorbent body pressurizing portion 92 is inclined in the longitudinal direction L, when the wearer's feet are twisted in the oblique direction, it is easy to follow the movement of the foot and deform.
又，吸收體30係當吸收性物品1被自寬度方向外側朝內側按壓時，沿著第2吸收體壓榨部92折彎。此時，由於第1直線C1與第2直線C2是對長度方向L傾斜配置，故，可抑制吸收性物品1沿著長度方向L折彎。又，第2吸收體壓榨部92之格子狀為長度方向L較寬度方向W長之菱形形狀，故，體液不易朝寬度方向W擴散。 Moreover, when the absorbent article 1 is pressed from the outer side in the width direction to the inner side, the absorbent body 30 is bent along the second absorbent body press portion 92. At this time, since the first straight line C1 and the second straight line C2 are disposed obliquely to the longitudinal direction L, it is possible to suppress the absorbent article 1 from being bent in the longitudinal direction L. Further, since the lattice shape of the second absorber press portion 92 is a rhombic shape in which the longitudinal direction L is longer than the width direction W, the body fluid is less likely to diffuse in the width direction W.
藉由第2吸收體壓榨部92區劃複數個小區域31。小區域31係在與鄰接的其他小區域之邊界亦即第2吸收體壓榨部92，厚度變得最小，在平面視角之小區域的中央( 小區域的長度方向之中央及寬度方向之中央)厚度變得最大。如此，藉由縮小區劃小區域之第2吸收體壓榨部92的厚度且相對地增大小區域31的中央之厚度，能夠使小區域的中央接近表面薄片側。因此，在小區域的中央，在表面薄片10所吸入之體液變得容易移行至吸收體30，可提高體液的吸入性。 The plurality of small regions 31 are divided by the second absorber press portion 92. The small area 31 is at the boundary with the other small area adjacent thereto, that is, the second absorber press part 92, and the thickness is minimized, and is at the center of a small area of the plane view angle ( The thickness of the center of the small area in the longitudinal direction and the center of the width direction becomes the largest. In this manner, by narrowing the thickness of the second absorbent body pressurizing portion 92 of the small area and relatively increasing the thickness of the center of the small region 31, the center of the small region can be brought close to the surface sheet side. Therefore, in the center of the small area, the body fluid sucked into the surface sheet 10 easily migrates to the absorber 30, and the inhalation of the body fluid can be improved.
又，藉由使厚度在小區域的邊界與小區域的中央不同，能夠提高吸收體30的立體感。具立體感的吸收體30係比起平面性的吸收體30，更能感到高吸收性能。因此，使用者可藉由視覺掌握吸收性能，獲得安心感。又，表面薄片10係沿著吸收體壓榨部90的凹凸撓曲配置著，經由表面薄片10可視認吸收體壓榨部90。經由表面薄片10可視認係指透過表面薄片10可視認吸收體壓榨部90的至少一部分之狀態。使用者藉由視認吸收體壓榨部90，能夠經由表面薄片10感到吸收體30的膨脹。因此，使用者可依據視覺來掌握吸收性能，能夠獲得安心感。 Further, by making the thickness of the small region different from the center of the small region, the three-dimensional feeling of the absorber 30 can be improved. The three-dimensional absorbent body 30 is more absorbing than the planar absorbent body 30. Therefore, the user can gain a sense of security by visually grasping the absorption performance. Further, the surface sheet 10 is disposed along the unevenness of the absorbent body press portion 90, and the absorbent body press portion 90 is visible through the surface sheet 10. The state through the surface sheet 10 means that at least a part of the absorber press portion 90 is visible through the surface sheet 10. By visually recognizing the absorber press portion 90, the user can feel the expansion of the absorber 30 via the surface sheet 10. Therefore, the user can grasp the absorption performance according to the vision, and can obtain a sense of security.
第2吸收體壓榨部92係在第1直線C1與第2直線C2上間歇地形成有複數個。因此，在鄰接的第2吸收體壓榨部92彼此相互之間，配置未壓榨之區域，能夠藉由配置於此未壓榨之區域的高吸收性聚合物來保持體液。比起在鄰接的第2吸收體壓榨部彼此相互之間未配置有未壓榨之區域的結構(第2吸收體壓榨部連續形成之結構)，能夠將用來保持體液的區域均等地配置在吸收體全體。再者，本實施形態之第2吸收體壓榨部92彼此之間隔為2mm 。再者，第2吸收體壓榨部92係抑制吸收體30之高吸收性聚合物偏靠或高吸收性聚合物溢出。在抑制高吸收性聚合物的偏靠等之觀點，期望第2吸收體壓榨部92之間隔為2mm以下。 The second absorber press portion 92 is intermittently formed in plural numbers on the first straight line C1 and the second straight line C2. Therefore, an uncompressed region is disposed between the adjacent second absorbent body press portions 92, and the body fluid can be held by the superabsorbent polymer disposed in the uncompressed region. The structure for continuously holding the body fluid can be uniformly disposed in the absorption structure in which the unexpressed region is not disposed between the adjacent second absorbent body press portions (the second absorbent body press portion is continuously formed). The whole body. Further, the second absorber press portions 92 of the present embodiment are spaced apart from each other by 2 mm. . Further, the second absorber press portion 92 suppresses the overflow of the highly absorbent polymer of the absorber 30 or the overflow of the superabsorbent polymer. From the viewpoint of suppressing the bias of the superabsorbent polymer, etc., it is desirable that the interval between the second absorber press portions 92 is 2 mm or less.
圖4係表面薄片10之平面圖。在表面薄片10形成有朝厚度方向T壓榨之表面薄片壓榨部80。表面薄片壓榨部80係具有花紋形狀之第1表面薄片壓榨部81、點狀之第2表面薄片壓榨部82及第3表面薄片壓榨部83。第2表面薄片壓榨部82之徑為2mm，第3表面薄片壓榨部83之徑為1.4mm。 Figure 4 is a plan view of the surface sheet 10. The surface sheet 10 is formed with a surface sheet press portion 80 which is pressed in the thickness direction T. The surface sheet press portion 80 is a first surface sheet press portion 81 having a pattern shape, a second surface sheet press portion 82 having a dot shape, and a third surface sheet press portion 83. The diameter of the second surface sheet press portion 82 is 2 mm, and the diameter of the third surface sheet press portion 83 is 1.4 mm.
第1表面薄片壓榨部81係僅花紋形狀的輪廓部分被壓縮。另外，第2表面薄片壓榨部82及第3表面薄片壓榨部83，不僅輪廓部分，圓形全體被壓縮。 The first surface sheet press portion 81 is only compressed in the outline portion of the pattern shape. Further, the second surface sheet press portion 82 and the third surface sheet press portion 83 are not only contoured but also the entire circular shape is compressed.
第2表面薄片壓榨部82及第3表面薄片壓榨部83係間歇地配置於延伸在長度方向L第3直線C3與第4直線C4上。此第3直線C3與第4直線C4係交叉著，配置成格子狀。再者，第3直線C3與第4直線C4在圖3中分別以一點鏈線顯示。第3直線C3係對配置有第2吸收體壓榨部92之第1直線C1傾斜。第4直線C4係對配置有第2吸收體壓榨部92之第2直線C2傾斜。 The second top sheet press portion 82 and the third top sheet press portion 83 are intermittently arranged on the third straight line C3 and the fourth straight line C4 extending in the longitudinal direction L. The third straight line C3 intersects with the fourth straight line C4 and is arranged in a lattice shape. Further, the third straight line C3 and the fourth straight line C4 are respectively shown by a one-dot chain line in FIG. The third straight line C3 is inclined with respect to the first straight line C1 in which the second absorber press portion 92 is disposed. The fourth straight line C4 is inclined with respect to the second straight line C2 in which the second absorber press portion 92 is disposed.
由於沿著表面薄片壓榨部80的延伸方向之直線與沿著吸收體壓榨部90的延伸方向之直線不同，故，在表面薄片10中剛性高之區域、和在吸收體30中剛性高之區域係沿著不同方向配置著。剛性高之區域不會沿著任意的一 方向集中配置，能夠在吸收性物品全體均等地設置剛性高之區域。 Since the straight line along the extending direction of the surface sheet press portion 80 is different from the straight line along the extending direction of the absorbent body press portion 90, the region having high rigidity in the surface sheet 10 and the region having high rigidity in the absorbent body 30 The system is arranged in different directions. The area with high rigidity will not follow any one By arranging the directions in a concentrated manner, it is possible to uniformly provide an area having high rigidity in the entire absorbent article.
在從對表面薄片10呈垂直的直線上之表面薄片側的視點(圖5中所示的X)，在小區域31分別重疊有表面薄片壓榨部80。重疊於小區域之表面薄片壓榨部80的配置圖案係構成為在每個小區域31不同。配置圖案係指重疊於此小區域之表面薄片壓榨部的面積對小區域的面積之比例亦即壓榨率。又，配置圖案為例如表面薄片壓榨部的種類(形狀及大小)。 On the side of the surface sheet side on the straight line perpendicular to the surface sheet 10 (X shown in Fig. 5), the surface sheet press portion 80 is superposed on the small area 31, respectively. The arrangement pattern of the surface sheet press portion 80 superimposed on the small area is configured to be different in each small area 31. The arrangement pattern refers to the ratio of the area of the surface sheet press portion overlapping the small area to the area of the small area, that is, the crush rate. Further, the arrangement pattern is, for example, the type (shape and size) of the surface sheet press portion.
表面薄片中形成有表面薄片壓榨部80之部分係剛性較高，而未形成有表面薄片壓榨部80之部分剛性較低。又，吸收體30中形成有吸收體壓榨部90之部分係剛性較高，而未形成有吸收體壓榨部90之部分剛性較低。亦即，吸收性物品1係具有剛性低而容易變形之部分；和剛性高而容易維持形狀之部分。具體而言，具有：表面薄片壓榨部80及吸收體壓榨部90在厚度方向重疊而配置之部分；僅形成有表面薄片壓榨部80之部分；僅形成有吸收體壓榨部90之部分；以及未形成有任一壓榨部之部分。 The portion of the surface sheet in which the surface sheet press portion 80 is formed is relatively rigid, and the portion where the surface sheet press portion 80 is not formed is less rigid. Further, the portion of the absorber 30 in which the absorber press portion 90 is formed is high in rigidity, and the portion in which the absorber press portion 90 is not formed is low in rigidity. That is, the absorbent article 1 has a portion having low rigidity and being easily deformed, and a portion having high rigidity and easily maintaining the shape. Specifically, the surface sheet press portion 80 and the absorber press portion 90 are disposed so as to overlap each other in the thickness direction; only the portion of the surface sheet press portion 80 is formed; only the portion of the absorber press portion 90 is formed; A portion of any of the press sections is formed.
若依據如此所構成之吸收性物品，當因穿用者的動作所產生之外力作用時，能夠以表面薄片壓榨部80、吸收體壓榨部90等作為起點，使未形成有表面薄片壓榨部80、吸收體壓榨部90之部分變形。由於表面薄片壓榨部80的配置圖案與吸收體壓榨部90的配置圖案不同，故，藉由表面薄片壓榨部80與吸收體壓榨部90之組合，能夠在吸 收性物品全體不規則地配置被壓榨之區域。比起表面薄片全體被均等地壓榨之吸收性物品，變得容易追隨不規則的動作而變形，能夠減低穿用時之不舒適感。再者，在吸收性物品中，未形成有任一壓榨部之部分，其厚度較形成有壓榨部之部分大，故，能夠發揮將體液迅速地吸入之海綿的功能，且成為柔軟之肌膚觸感。 According to the absorbent article configured as described above, when a force acts by the action of the wearer, the surface sheet press portion 80, the absorber press portion 90, and the like can be used as a starting point, so that the surface sheet press portion 80 is not formed. The part of the absorber press section 90 is deformed. Since the arrangement pattern of the surface sheet press portion 80 is different from the arrangement pattern of the absorber press portion 90, it can be sucked by the combination of the surface sheet press portion 80 and the absorber press portion 90. The whole of the retractable items is irregularly arranged in the crushed area. The absorbent article which is uniformly pressed against the entire surface sheet is easily deformed following the irregular movement, and the discomfort during wearing can be reduced. Further, in the absorbent article, the portion of the absorbent portion is not formed, and the thickness thereof is larger than the portion in which the press portion is formed. Therefore, the function of quickly inhaling the body fluid into the sponge can be exhibited, and the soft skin can be touched. sense.
又，小區域31係具備有第1小區域31A與第2小區域31B，重疊於第1小區域31A之表面薄片壓榨部80的配置圖案與重疊於第2小區域31B之表面薄片壓榨部80的配置圖案係構成為不同。具體而言，表面薄片壓榨部80的面積對小區域31的面積之比率亦即壓榨率不同。壓榨率不同的小區域，剛性也不同。因此，在吸收性物品全體，能夠不規則地配置剛性不同的小區域。比起吸收性物品全體的剛性均等之吸收性物品，變得容易追隨不規則的動作而變形，能夠減低穿用時的不舒適感。再者，本實施形態之小區域的最高壓榨率為17%，最低壓榨率為8%。 Further, the small region 31 includes the first small region 31A and the second small region 31B, and the arrangement pattern of the surface sheet press portion 80 superposed on the first small region 31A and the surface sheet press portion 80 superposed on the second small region 31B. The configuration pattern is configured differently. Specifically, the ratio of the area of the surface sheet press section 80 to the area of the small area 31, that is, the press rate is different. Small areas with different crush rates have different stiffness. Therefore, in the entire absorbent article, small areas having different rigidity can be arranged irregularly. The absorbent article having the same rigidity as the entire absorbent article is easily deformed following an irregular movement, and the feeling of discomfort during wearing can be reduced. Further, in the small area of the present embodiment, the highest crushing ratio was 17%, and the lowest crushing ratio was 8%.
在各區域，構成為第1表面薄片壓榨部81、第2表面薄片壓榨部82及第3表面薄片壓榨部83中至少2種表面薄片壓榨部80重疊。由於在1個小區域31，具備複數種類的表面薄片壓榨部，故，能夠在各小區域設置剛性高的部分與剛性低的部分。比起各小區域的剛性均等之吸收性物品，能夠平衡地不規則配置表面薄片壓榨部80，可提高吸收性物品全體的剛性。 In each of the regions, at least two types of surface sheet press portions 80 of the first top sheet press portion 81, the second top sheet press portion 82, and the third top sheet press portion 83 are overlapped. Since a plurality of types of surface sheet press sections are provided in one small area 31, it is possible to provide a portion having high rigidity and a portion having low rigidity in each small area. The surface sheet press portion 80 can be irregularly arranged in a balanced manner compared to the absorbent article having the same rigidity in each small region, and the rigidity of the entire absorbent article can be improved.
小區域31具有鄰接於表面薄片壓榨部80之第1區域 R1；和與表面薄片壓榨部80分離的第2區域R2。重疊於第1區域的表面薄片壓榨部80的面積對第1區域R1的面積之壓榨比率係較重疊於第2區域R2的表面薄片壓榨部80的面積對第2區域R2的面積之壓榨比率高(參照圖1)。如此，藉由如此配置表面薄片壓榨部80，能夠縮小第2吸收體壓榨部92附近的厚度，能夠使得因第2吸收體壓榨部92所產生之吸收體30的凹凸更顯眼而作出立體感。 The small area 31 has a first area adjacent to the surface sheet press section 80 R1; and a second region R2 separated from the surface sheet press portion 80. The area ratio of the area of the surface sheet press portion 80 superposed on the first region to the area of the first region R1 is higher than the area ratio of the area of the surface sheet press portion 80 overlapping the second region R2 to the area of the second region R2. (Refer to Figure 1). By arranging the surface sheet press portion 80 in this manner, the thickness of the vicinity of the second absorber press portion 92 can be reduced, and the unevenness of the absorber 30 generated by the second absorber press portion 92 can be made more conspicuous.
又，藉由表面薄片壓榨部80與吸收體壓榨部90的配置圖案不同，使得在吸收體30的每個小區域中體液的吸收態樣不同。其次，參照圖5詳細地說明體液的吸收態樣。圖5(a)為圖1所示的A-A斷面之斷面圖，圖5(b)係圖1所示的B-B斷面之斷面圖。 Further, by the arrangement pattern of the surface sheet press portion 80 and the absorber press portion 90, the absorption state of the body fluid is different in each small region of the absorber 30. Next, the absorption state of the body fluid will be described in detail with reference to Fig. 5 . Fig. 5 (a) is a cross-sectional view taken along line A-A of Fig. 1, and Fig. 5 (b) is a cross-sectional view taken along line B-B of Fig. 1.
在表面薄片10，間歇地形成有複數個表面薄片壓榨部80，附著於表面薄片10上之體液會被表面薄片壓榨部80迅速地吸入至表面薄片10內。在表面薄片壓榨部80的下方，配置著形成有吸收體壓榨部90的區域或未形成有吸收體壓榨部90的區域。又，在未形成有吸收體壓榨部的區域被配置在表面薄片壓榨部的下方之部分，能夠將從表面薄片吸入至吸收體的液體在未形成有吸收體壓榨部之區域予以保持。又，一旦移行至吸收體的體液會被高吸收性聚合物所保持而不會移行至穿用者側。因此，能夠防止體液的逆流產生。 In the surface sheet 10, a plurality of surface sheet press portions 80 are intermittently formed, and the body fluid adhering to the surface sheet 10 is quickly sucked into the surface sheet 10 by the surface sheet press portion 80. Below the surface sheet press portion 80, a region where the absorber press portion 90 is formed or a region where the absorber press portion 90 is not formed is disposed. Further, in a region where the absorber press portion is not formed, the portion which is disposed below the surface sheet press portion can hold the liquid sucked from the top sheet to the absorber in a region where the absorber press portion is not formed. Further, once the body fluid that has migrated to the absorbent body is held by the superabsorbent polymer, it does not migrate to the wearer side. Therefore, it is possible to prevent the backflow of the body fluid from occurring.
若依據如此結構之吸收性物品，既可抑制吸收性物品的厚度，又可確保體液的吸入性。例如，本實施形態之吸 收性物品係可理想地使用於厚度4mm以下的較薄型吸收性物品。更理想為能夠適用於厚度3mm以下的薄型吸收性物品。本實施形態之吸收性物品的具體的厚度大約2.5mm。 According to the absorbent article having such a structure, the thickness of the absorbent article can be suppressed, and the inhalation of the body fluid can be ensured. For example, the suction of this embodiment The retractable article can be desirably used for a thin absorbent article having a thickness of 4 mm or less. More preferably, it can be applied to a thin absorbent article having a thickness of 3 mm or less. The specific thickness of the absorbent article of the present embodiment is about 2.5 mm.
由於第2表面薄片壓榨部82及第3表面薄片壓榨部83係面積較小且形成於表面薄片10的全體範圍，故，在表面薄片全體可吸收少量的體液。但，在大量的體液一次被排出之情況，可在面積較大的第1表面薄片壓榨部81暫時儲存體液並移行至吸收體。 Since the second surface sheet press portion 82 and the third surface sheet press portion 83 have a small area and are formed over the entire surface sheet 10, a small amount of body fluid can be absorbed in the entire surface sheet. However, when a large amount of body fluid is discharged at a time, the body fluid can be temporarily stored in the first surface sheet press portion 81 having a large area and transferred to the absorber.
且，吸收性物品係具有：位於吸收性物品的長度方向之中央的中央區域CA(參照圖1)；和比起中央區域CA位於更靠長度方向外側之長度方向外側區域LA(參照圖1)。壓榨率係比起位於中央區域CA的小區域31A、31B、31C，位於長度方向外側區域LA之小區域31D、31E、31F、31G較高。 Further, the absorbent article has a central region CA (see FIG. 1) located at the center in the longitudinal direction of the absorbent article, and a longitudinal outer lateral region LA located outward in the longitudinal direction from the central region CA (see FIG. 1). . The crush ratio is higher than the small regions 31A, 31B, and 31C located in the central region CA, and the small regions 31D, 31E, 31F, and 31G located in the longitudinal outer region LA are higher.
位於吸收性物品1的長度方向中央之中央區域CA係包含穿用者的肌膚抵接之排泄口抵接區域。在表面薄片中未形成有表面薄片壓榨部的部分係比起形成有表面薄片壓榨部的部分，蓬鬆度高且暫時被吸入的體液不易逆流。因此，藉由將位於此中央區域的小區域之壓榨比率作成為較長度方向外側區域的壓榨比例小，能夠抑制穿用者的排泄口附近之體液逆流。又，藉由將位於中央區域的小區域之壓榨比率作成為較長度方向外側區域的壓榨比例小，可降低穿用者的排泄口附近之剛性，能夠提昇肌膚觸感。 The central area CA located at the center in the longitudinal direction of the absorbent article 1 is an excretion opening abutting region where the wearer's skin abuts. The portion in which the surface sheet press portion is not formed in the surface sheet is higher than the portion in which the surface sheet press portion is formed, and the bodily fluid having a high bulkiness and temporarily sucked is not easily reversed. Therefore, by making the pressing ratio of the small region located in the central region smaller than the pressing ratio in the outer region in the longitudinal direction, it is possible to suppress the backflow of the body fluid in the vicinity of the excretory opening of the wearer. Further, by setting the pressing ratio in the small region located in the central region to a smaller pressing ratio in the outer region in the longitudinal direction, the rigidity in the vicinity of the excretory opening of the wearer can be reduced, and the feeling of the skin can be improved.
再者，壓榨部係至少將表面薄片10或吸收體30朝厚度方向T壓榨而形成即可，能夠採用各種結構。例如，能夠藉由沖壓加工、壓花加工等來形成，其形狀亦可為格子網、蜂巢形狀等。 Further, the press section may be formed by at least pressing the surface sheet 10 or the absorber 30 in the thickness direction T, and various structures can be employed. For example, it can be formed by press working, embossing, or the like, and the shape thereof may be a lattice mesh or a honeycomb shape.
其次，參照圖6說明關於本實施形態之吸收性物品1的製造方法的一部分。再者，關於圖6中未記載的方法，能夠採用既存的方法。吸收性物品的製造方法係如圖6所示，在步驟101，進行表面薄片生成製程。具體而言，藉由熱熔膠接著劑將構成表面薄片10的頂面薄片11與第2薄片12予以接著。其次，將接著有頂面薄片11與第2薄片12之表面薄片10朝厚度方向T進行壓縮加工，形成表面薄片壓榨部80。此壓縮加工係例如藉由使表面薄片10通過進行加熱及加壓之壓花滾子，形成格子狀的凹凸加工。 Next, a part of the method of manufacturing the absorbent article 1 of the present embodiment will be described with reference to Fig. 6 . Furthermore, with respect to the method not shown in FIG. 6, the existing method can be used. The manufacturing method of the absorbent article is as shown in FIG. 6, and in step 101, a surface sheet forming process is performed. Specifically, the top sheet 11 and the second sheet 12 constituting the surface sheet 10 are adhered by a hot melt adhesive. Next, the top sheet 11 and the surface sheet 10 of the second sheet 12 are subjected to compression processing in the thickness direction T to form the surface sheet press portion 80. This compression processing is performed by, for example, passing the surface sheet 10 through an embossing roller that is heated and pressurized to form a lattice-like uneven processing.
在步驟102，進行表面薄片接合製程。具體而言，藉由熱熔融，將表面薄片10與側薄片41、42予以接著。 At step 102, a surface sheet bonding process is performed. Specifically, the surface sheet 10 and the side sheets 41, 42 are followed by heat fusion.
其次，在步驟103，進行吸收體成形製程。具體而言，以不織布包住吸收體的材料之SAP，形成吸收體壓榨部90。再者，步驟101及102的表面薄片生成製程及表面薄片接合製程、和步驟103的吸收體成形製程的順序亦可相反。 Next, at step 103, an absorber forming process is performed. Specifically, the SAP pressurizing portion 90 is formed by a SAP which does not wrap the material of the absorbent body. Furthermore, the order of the surface sheet forming process and the surface sheet bonding process of steps 101 and 102 and the absorber forming process of step 103 may be reversed.
在步驟104，進行接合製程。具體而言，進行將在步驟102所生成之表面薄片10及側薄片41、42、和在步驟103所成形的吸收體30予以接合之接合製程。 At step 104, a bonding process is performed. Specifically, a bonding process of joining the surface sheet 10 and the side sheets 41, 42 produced in the step 102 and the absorber 30 formed in the step 103 is performed.
在步驟105，進行裏面薄片接合製程。具體而言，將 吸收體及表面薄片等與裏面薄片20接合。再者，在圖6中，雖未圖示，在接合裏面薄片20後，具備有塗佈黏著劑之製程。藉由上述製程，能夠製造本實施形態之吸收性物品。 At step 105, an inner sheet bonding process is performed. Specifically, The absorber, the surface sheet, and the like are joined to the inner sheet 20. Further, in Fig. 6, although not shown, after the inner sheet 20 is joined, a process of applying an adhesive is provided. According to the above process, the absorbent article of the present embodiment can be produced.
如上述般，透過本發明的實施形態揭示了本發明的內容，但，成為此揭示的一部分之論述及圖面不是用來限定本發明者。由此揭示，在不超出本發明的技術思想範圍內，其他的代替實施形態、變形實施例、運用技術等亦包含於本發明。 As described above, the present invention has been disclosed by the embodiments of the present invention. However, the description and drawings are not intended to limit the invention. Therefore, other alternative embodiments, modified embodiments, operational techniques, and the like are also included in the present invention without departing from the scope of the present invention.
例如，本實施形態之小區域係第1直線及第2直線配置成等間隔，藉由第2吸收體壓榨部呈規格性地被區劃，但，藉由第2吸收體壓榨部所區劃之小區域亦可非規格性地配置著。例如，亦可構成為第1直線及第2直線的間隔不同，藉由第2吸收體壓榨部所區劃之小區域呈不規則地被配置著。 For example, in the small area of the present embodiment, the first straight line and the second straight line are arranged at equal intervals, and the second absorbent body press portion is regularly divided. However, the second absorbent body press portion is small. The area can also be configured in a non-standard manner. For example, the interval between the first straight line and the second straight line may be different, and the small area partitioned by the second absorbent body press portion may be irregularly arranged.

(表面水分指數的測定方法) (Method for measuring surface moisture index)
使用形成有U字狀凹部的下述使用機器，將吸收性物品黏貼於使用機器的凹部底面，對吸收性物品的長度方向之中央，以下述的條件滴下人工尿液，在滴下45秒後將吸收性物品載置於試料固定台，在吸收性物品上放置感測器。在滴下1分鐘後開始感測器的水分掃描，算出殘留於吸收性物品表面之水分指標的表面水分指數。表面水分指數的測定係在吸收性物品的長度方向中央之1個部位進行測定，且在從中央朝長度方向外側各3mm偏移的4個部位進行測定。算出合計5個部位的測定值之平均值。再者，表面水分指數為電壓(V)×係數(10)-1.5。 The absorbent article was adhered to the bottom surface of the concave portion of the use machine by using the following machine in which the U-shaped concave portion was formed, and the artificial urine was dropped on the center of the longitudinal direction of the absorbent article under the following conditions, and after dropping for 45 seconds, The absorbent article is placed on a sample fixing station, and a sensor is placed on the absorbent article.

(評價結果) (Evaluation results)
評價結果顯示於表1。 The evaluation results are shown in Table 1.
實施例1及實施例2之吸收性物品的表面水分指數皆為10以下。另外，比較例之吸收性物品超過10。再者，表面水分指數係顯示數值越高則濕潤感越高。表面水分指數係對應於官能測試之濕潤感。5以下的表面水分指數係為以手接觸表面薄片時完全不會感到水分存在之等級。5以上10以下之表面水分指數係為以手接觸表面薄片時會感到有稍許水分，但不會不舒服之等級。而10以上20以下之的表面水分指數係為以手接觸表面薄片時，會有人感到不舒適之等級。20以上的表面水分指數係為以手接觸表面薄片時令人非常不舒服之等級。 The surface moisture indexes of the absorbent articles of Examples 1 and 2 were all 10 or less. In addition, the absorbent article of the comparative example exceeded 10. Furthermore, the surface moisture index shows that the higher the value, the higher the moisturizing feeling. The surface moisture index corresponds to the moist feel of the functional test. A surface moisture index of 5 or less is a level at which no moisture is felt at all when the surface sheet is touched by hand. The surface moisture index of 5 or more and 10 or less is a level which will feel a little moisture when the surface is in contact with the hand, but will not be uncomfortable. On the other hand, the surface moisture index of 10 or more and 20 or less is a level at which people feel uncomfortable when they touch the surface sheet by hand. A surface moisture index of 20 or more is a very uncomfortable level when the surface sheet is touched by hand.
實施例1及實施例2之吸收性物品的表面水分指數皆為10以下，可得知具有高體液吸入性。從維持體液吸入性的觀點來看，表面薄片的壓榨率，期望為7.5%以上。另外，當表面薄片的壓榨率過高時，則表面薄片的剛性會變得過高，不易追隨身體的動作而變形。從確保柔軟性的觀點來看，表面薄片的壓榨率，期望為50%以下。 The surface moisture indexes of the absorbent articles of Examples 1 and 2 were all 10 or less, and it was found that the body absorbent has high body fluid inhalation. From the viewpoint of maintaining body fluid inhalability, the pressing ratio of the surface sheet is desirably 7.5% or more. Further, when the pressing ratio of the surface sheet is too high, the rigidity of the surface sheet becomes too high, and it is difficult to deform in accordance with the movement of the body. From the viewpoint of ensuring flexibility, the pressing ratio of the surface sheet is desirably 50% or less.

In the sample, the MD sample in the longitudinal direction of the sample along the transport direction MD of the absorbent article and the CD sample in the cross direction CD intersecting the transport direction in the longitudinal direction of the sample are prepared. In the MD sample, the absorbent article is in an extended state, and a mark is given to the center of the longitudinal direction. A cross mark is drawn every 25 mm from the center mark toward the outside in the longitudinal direction. Next, a line is drawn every 35 mm from the center mark toward the outside in the longitudinal direction, and the position of the line is cut. The center of the length direction of the cut sample is fitted to the center of the crotch portion of the undergarment, and the sample is attached to the undergarment.
CD試料係將吸收性物品作成為伸長之狀態，對長度方向之中央賦予記號。在從中央的記號朝寬度方向外側每隔25mm的位置，畫上十字記號。其次，將試料的長度方向之中央配合內褲的胯下部之中央，將試料連貼於內褲。 The CD sample is in a state in which the absorbent article is stretched, and a mark is given to the center of the longitudinal direction. A cross mark is drawn every 25 mm from the center mark toward the outer side in the width direction. Next, the center of the longitudinal direction of the sample was fitted to the center of the crotch portion of the undergarment, and the sample was attached to the undergarment.
使用扭矩試驗機，以上部夾具夾持試料，使各試料的一方的十字記號成為夾具內側端部，並且也以下部夾具夾 持試料，使另一方的十字記號成為夾具內側端部。再者，此時，夾具的中央係配置成重疊於試料的十字之長度方向的線上。夾具間之MD試料的長度尺寸為50mm，夾具間之CD試料的長度尺寸為30mm。 Using a torque tester, the upper clamp clamps the sample so that one of the cross marks of each sample becomes the inner end of the clamp, and also the lower clamp Hold the sample so that the other cross mark becomes the inner end of the clamp. Further, at this time, the center of the jig is placed so as to overlap the line in the longitudinal direction of the cross of the sample. The length of the MD sample between the jigs was 50 mm, and the length of the CD sample between the jigs was 30 mm.
MD試料係為將以沿著吸收性物品的長度方向之軸為中心的旋轉方向扭轉試料，測定試料之應力。CD試料係將以沿著吸收性物品的寬度方向之軸為中心的旋轉方向扭轉試料，測定試料之應力。旋轉方向之扭轉係扭轉至下述的旋轉角度後，朝相反方向旋轉(返回成無扭轉之狀態)。扭矩值係在從尚未變形之狀態旋轉成扭轉至下述旋轉角度時進行測定。測定MD試料之扭矩值，且測定CD試料之扭矩值，將這些扭矩值之平均值作為各吸收性物品的扭矩值。 In the MD sample, the sample was twisted in a direction of rotation about the axis along the longitudinal direction of the absorbent article, and the stress of the sample was measured. In the CD sample, the sample was twisted in the direction of rotation about the axis in the width direction of the absorbent article, and the stress of the sample was measured. The torsion in the direction of rotation is twisted to the following rotation angle, and then rotated in the opposite direction (returning to a state of no twist). The torque value is measured when it is rotated from a state in which it has not been deformed to a rotation angle to the following rotation angle. The torque value of the MD sample is measured, and the torque value of the CD sample is measured, and the average value of these torque values is taken as the torque value of each absorbent article.
(試驗條件) (Test conditions)
-旋轉速度…MD試料：30rpm、CD試料：30rpm - Rotation speed... MD sample: 30 rpm, CD sample: 30 rpm
-旋轉角度(反轉位置之角度)…MD試料：50°、CD試料：65° - Rotation angle (angle of reverse position)... MD sample: 50°, CD sample: 65°
-測定角度…MD試料：45°、CD試料：60° - Measurement angle... MD sample: 45°, CD sample: 60°
-旋轉次數…1次 - number of rotations... 1 time
(評價結果) (Evaluation results)
評價結果顯示於表2 The evaluation results are shown in Table 2.
從上述可得知，比較例1至比較例5之扭矩值皆超過20N。相對於此，實施例之扭矩值為16.8N，比起比較例之扭矩值小非常多，相對於朝旋轉方向之扭轉，容易變形。 As can be seen from the above, the torque values of Comparative Examples 1 to 5 all exceeded 20N. On the other hand, the torque value of the example was 16.8 N, which was much smaller than the torque value of the comparative example, and was easily deformed with respect to the torsion in the rotational direction.
