Description

吸收性物品 The absorbent article

技术领域 FIELD

本发明涉及生理用卫生巾和一次性尿布、吸尿垫、短内裤衬里等吸收性物品,特别是涉及透液性能良好,并且可以对穿用者的皮肤产生缓冲性的吸收性物品。 The present invention relates to a sanitary napkin and a disposable diaper, a urine absorbent pad, absorbent articles such as panty liners, and more particularly to a good performance of the liquid-permeable, and may generate a buffer absorbent article to the wearer's skin.

背景技术 Background technique

作为生理用卫生巾和一次性尿布等吸收性物品的受液侧表面材料往往使用开孔薄膜。 As a sanitary napkin and a disposable diaper is an absorbent article the liquid-receiving side surface of the apertured film materials tend to be used.

这种开孔薄膜的制作方法如下:对表面具有许多孔的筛网滚筒上供给烯烃类树脂薄膜,然后再用热风使树脂软化的同时利用筛网滚筒内部的吸引压力在上述树脂薄膜上形成对应上述滚筒孔的孔,同时使开孔周围的薄膜向薄膜的一侧突出而形成导液管。 This method of manufacturing a perforated film is as follows: an olefin-based resin film supplying screened cylinder having a plurality of surface pores and then with hot air to soften the resin while utilizing the suction pressure inside the drum screen is formed on the resin film corresponding to hole of the cylinder hole, while the film around the opening to the protruding side of the film to form the catheter.

如果利用开孔薄膜作为受液侧表面材料,则可以使流到薄膜表面上的液体通过开孔被吸液层吸收。 If the use of apertured films as a liquid receiving side surface of the receiving material, the liquid can flow onto the surface of the film opening is absorbed by the liquid-absorbing layer. 通过预先把上述开孔薄膜制成白色,可以达到遮蔽被吸液层吸收的经血等液体颜色的效果。 By the pre-formed white film of the aperture, the shielding can be achieved by a liquid such as menstrual blood absorbed by the color liquid-absorbent layer effect.

利用膨松性比较大的气穿型无纺布等作为受液侧表面材料,利用交错形成的成直线形延伸的凸条和凹槽的结构,并使用将上述凸条和凹槽朝吸收性物品的纵向配置的结构。 Use relatively large loft air-through non-woven fabric or the like as the groove and the ridge toward the liquid receiving side surface of the absorbent material, the use of ribs and grooves of rectilinear structures formed alternately extending, and using vertical arrangement of the configuration of the article. 这种表面片对穿用者的皮肤具有缓冲性,并具有与皮肤的接触柔软的优点。 Such a surface sheet having a buffering property to the skin of the wearer, and having a soft contact with the skin of advantages.

然而,采用开孔薄膜的表面材料在多量液体流到该表面上时,不能使所有的液体从开孔快速导入吸液层,在薄膜表面上可能残留液体。 However, with the opening surface of the film material in a large amount of liquid to flow over the surface, not all of the liquid absorbent layer quickly introduced from the opening, the liquid may remain on the film surface. 一旦在薄膜表面上有液体残留,该液体就会沿薄膜表面向吸收性物品的纵向和横向流动,而容易使穿用者的皮肤有湿润感,并有发生液体从吸收性物品的表面向横向漏出的危险。 Once the liquid remaining on the film surface, the film surface along which the liquid will be in the longitudinal and transverse flow of the absorbent article, and the skin of the wearer tends to have moist feeling, and the liquid to occur from the lateral surface of the absorbent article the risk of leakage.

另外,作为上述开孔薄脱,虽然在开孔的边缘部上形成有朝向吸液层的导液管,但因为这样的导液管作为硬度比较大的部分分散因而这种开孔薄膜会使穿用者的皮肤有刚性感(硬棒接触感)。 Further, as thin off said opening, while the opening formed on the edge portion of the catheter toward the liquid-absorbing layer, but because such a hardness as the catheter relatively large partial dispersion and thus this makes apertured film the wearer's skin just sexy (Yingbang sense of touch).

另外,在用具有凸条和凹槽的无纺布形成上述表面材料的情况下,液体容易沿凹槽内向吸收性物品的纵向流动,从而容易使穿用者在大范围内有湿润感。 Further, in the case of forming the surface of the nonwoven fabric material having a strip of protrusions and recesses, the liquid flows easily along the longitudinal grooves within the absorbent article, thereby easily wet the wearer with a feeling in a wide range. 因凸条形成为直线形状而这些凸条在被穿用者的皮肤压力压倒后,相邻的凸条重叠,在与皮肤接触时更容易有刚性感。 Convex stripe shape by a straight line and these ribs after being overwhelming pressure on the skin of the wearer, to overlap the adjacent ribs, in contact with the skin is more likely to have the feel of firmness.

发明内容 SUMMARY

本发明的任务是要解决现有技术中的上述问题,目的是提供一种能迅速透过液体,并具有与穿用者的皮肤柔软接触的表面材料的吸收性物品。 Object of the present invention is to solve the aforementioned problems of the prior art, the object is to provide a rapid liquid permeable, and the absorbent article having a soft contact with the skin of the wearer of the surface material.

本发明的吸收性物品具有里层、透液体的表面层和夹在上述里面层与上述表面层之间的吸液层,其特征在于:上述表面层由无纺布形成,上述表面层具有向表面侧隆起成凸状的规定面积的隆起部和以包围上述各隆起部并分隔各隆起部的状态连续形成的凹槽,断面形成为凹凸状,在上述凹槽内形成有透过液体用的孔。 The absorbent article of the present invention having the inner layer, the surface layer sandwiched between the back layer and the surface layer of the liquid-absorbent liquid-permeable layer, wherein: said surface layer is formed of a nonwoven fabric to the surface layer having a convex surface side of the ridge-like raised portions of a predetermined area and raised portions to surround each of the states of the respective dividing grooves and ridges formed continuously, formed in an uneven shape cross section, with a recess formed in said transmissive liquid hole.

如图1所示的生理用卫生巾1在不透液性的里面片2上面的中央区上配置吸液芯3,该吸液芯3的表面被表面层10覆盖。 Physiological shown in FIG wick napkin 1 is disposed on the upper 2 inside the liquid-impermeable sheet 3 with the central area, the surface of the wick 3 is covered with a surface layer 10. 在生理用卫生巾1的受液侧表面的左右两侧部上配置侧片5,5。 Side sheets 5, 5 disposed at right and left side portions sanitary napkin 1, the liquid-receiving side surface. 该侧片5,5与上述里面片2在左右两侧部上接合,再通过在吸液芯3的左右外侧折曲形成防漏壁6,6。 The side sheets 5, 5 in the above-described back sheet 2 on both sides of the left and right engaging portions, and then by forming the leakage preventing walls 6,6 wick 3 is bent around the outside. 为了构成上述防漏壁6,6而折起的上述侧片5,5与上述表面层10的左右两侧部上面接合。 It said side plate in order to form the leakage preventing wall 6,6 and 5,5 is engaged with the folded upper portion of the left and right sides of the surface layer 10.

在上述防漏壁6,6上分别接合有沿纵向(Y方向)延伸的弹性件7。 On the leakage preventing wall elastic members 6, 6 are joined along a longitudinal direction (Y direction) of 7. 借助于该弹性件7的收缩力使生理用卫生巾1朝纵向形成弯曲形状。 By means of which the elastic member 7 of the contractile force of the physiologically longitudinal curved shape towards the sanitary napkin 1. 结果可以使防漏壁6从生理用卫生巾1的受液侧表面立起。 Results from the leakage preventing walls 6 raised by the physiological liquid receiving side surface of the sanitary napkin 1.

上述表面层10由无纺布形成。 The surface layer 10 formed of a nonwoven fabric. 如图2和图3所示,上述表面层10由表面片11和衬里片12重叠形成。 2 and 3, the surface layer 10 is formed by the surface sheet 11 and backing sheet 12 overlap. 表面片11和衬里片12至少在局部接合。 The topsheet 11 and backing sheet 12 at least partially engaged.

在该表面层10上形成贯通表面片11和衬里片12的多个导液孔13。 Forming a plurality of liquid guiding through the surface sheet 11 and the holes 13 in the backing sheet 12 on the surface layer 10. 在图2和图4所示的吸收性物品中,上述孔13排列成直线状,在图4中用L1、L2表示上述孔13的排列线。 In the absorbent article shown in FIGS. 2 and 4, the hole 13 are linearly arranged in FIG. 4 by L1, L2 represents a line of the holes 13 are arranged. 在此排列线L1、L2是指通过排列成直线状的孔13的中心线的假想线。 In this arrangement lines L1, L2 refers to the imaginary line through the center line of the linearly arranged holes 13. 并且在孔13不配置成一列,而是在所规定宽度的带状范围内排列成多数列或随机排列时,L1、L2是指通过孔13排列的上述带状范围的宽度方向中心的假想线。 And when the hole 13 is not disposed in a row, but the majority are arranged in columns within the range of the width of the strip in the predetermined or random arrangement, L1, L2 refers to the imaginary line is the center of the strip width direction by a range of holes 13 arranged .

按照图2和图4所示的实施方式,上述排列线L1和L2分别与纵向(Y方向)形成有角度地延伸,被排列线L1和排列线L2包围的分隔区15是菱形,但本发明不限于菱形,也可以是平行四边形、长方形、正方形,甚至是五边形和六边形等。 According to the embodiment shown in FIG. 2 and FIG. 4, the arrangement lines L1 and L2 are respectively formed in the longitudinal (Y-direction) extending angularly, the row line L1 and line L2 are arranged separating region 15 is surrounded by a diamond, but the present invention is It is not limited to diamond-shaped, but may be a parallelogram, rectangle, square, pentagon and hexagon, etc. or even.

如图4所示,上述菱形的分隔区15的锐角朝向纵向(Y方向)。 4, the above-described diamond-shaped spacer acute zone 15 toward the longitudinal (Y-direction). 于是,在上述分隔区15内,形成有上述表面片11和里面片12一起朝向从吸液芯3上分离的表面方向隆起的隆起部16。 Thus, in the above-described spacer region 15, there is formed the topsheet 11 and the backsheet 12 with the raised section raised toward the direction away from the surface 3 on the wick 16. 上述隆起部16作为平面图形看到的形状是与上述分隔区15的菱形相似的形状,具体地说是在菱形的角部带有圆弧状的形状。 The shape of the protuberance 16 is a planar pattern with a diamond saw the partition region 15 of similar shape, particularly in the corner portion having an arc diamond shape.

上述隆起部16的周围被凹槽部17包围,通过上述凹槽部17使各隆起部16互相独立地被划分。 Around the raised portion 16 is surrounded by the recess portion 17, the groove portion 17 via the ridge portion 16 each independently of each other is divided. 按照图2和图4所示的实施方式,上述凹槽部17具有规定的宽度Wa并形成为直线形状,上述孔13和上述排列线L1和L2位于上述凹槽17宽度方向的中心,且位于凹槽17的底部。 According to the embodiment shown in FIG. 2 and FIG. 4, the groove portion 17 having the above-described predetermined width Wa is formed in a linear shape and the holes 13 and the arrangement lines L1 and L2 located at the center of the width direction groove 17, and is located the bottom of the groove 17.

如图3所示,表面层10的上述隆起部16的上面(表面)16a几乎是平坦的表面,从凹槽17的底部到上述上表面16a形成平缓的曲面。 3, the upper surface of the raised portion 16 of the surface layer 10 (surface) 16a almost flat surface, from the bottom of the groove 17 to the upper surface 16a forms a gentle curved surface. 如图3所示,在上述隆起部16的里侧还形成空间18。 As shown in FIG. 3, the space 18 is also formed on the back side of the raised portion 16.

表面层10上形成有上述隆起部16和上述凹槽部17的断面图是凹凸状的,但上述凹凸形状如图1所示,由覆盖吸液芯3的区域(宽度W内和纵向长度L范围内的区域)形成。 The protuberance 16 is formed with a sectional view and said recess portion 17 is uneven, but the embossed pattern shown in Figure 1, the area covered by the wick 3 in (width W and a longitudinal length L of the surface layer 10 range region) is formed. 但上述凹凸形状即可以只在覆盖上述吸液芯3的区域且只在比被上述宽度W和纵向长度L包围的区域窄的中央部上形成。 However, i.e., the embossed pattern may cover the area of ​​the absorbent core 3 and is formed only in the region surrounded narrower than the width W and the length L of the longitudinal central portion only. 上述凹凸部也可以在扩展到上述吸液芯3的轮廓外侧的广大的区域上形成。 The uneven portion may be extended to the majority of the area outside the contour of the liquid-absorbent core 3 is formed. 也可以在上述表面层10的整个区域上形成上述凹凸部。 The uneven portion may be formed on the entire surface region of the layer 10.

如图2和图3所示,上述里衬片12主要只配置在形成有上述凹凸形状的区域内,而在其它的区域上只在上述表面片11上形成表面层。 2 and 3, the liner sheet 12 is mainly arranged only in the region of the concave-convex shape is formed, and a surface layer formed on the other areas only on the surface of the sheet 11.

另外,按照一个优选的实施方式,在表面片11和里衬片12重叠的状态下对上述凹凸形状进行加热加压,结果使凹槽部17底部的纤维密度比隆起部16上表面16a的纤维密度高。 Further fiber density, according to a preferred embodiment, in the state of the surface sheet 11 and the liner sheet 12 overlapped on the embossed pattern is heated and pressed, with the result that the bottom of the groove portion 17 than the upper surface of the raised portion 16a of the fiber 16 high density.

采用该表面层10的生理卫生巾,虽然也可以使落到该表面层10上的液体透过表面层11和里衬层片12,但上述液体在上述分划的区域15内从隆起部16的上表面16a导入环绕其周围的凹槽部17中。 The use of the napkin surface layer 10 from the raised portion 16 15, although it is also possible to fall on the liquid surface 10 of the layer 12, but the liquid above the partition region 11 through the surface layer and the back liner sheet introducing around the upper surface 16a of the recess portion 17 therearound. 特别是在凹槽部17的纤维密度比隆起部16的纤维密度高时,通过凹槽部17的毛细管作用而使落在隆起部16上的液体迅速流入凹槽部17,特别是因每个的隆起部16都被凹槽部17环绕。 Particularly when the fiber density of the groove portion 17 is higher than the fiber density of the raised portion 16 by capillary action of the groove portion 17 falls on the raised portion 16 of the groove portion 17 flows into the liquid rapidly, particularly because each the raised portions 16 are surrounded by the recess portion 17. 所以使落到隆起部16上的液体非常迅速地导入到其周围的凹槽部17中。 So that the liquid falls on the raised portion 16 is rapidly introduced into the groove portion 17 therearound.

虽然导入在上述凹槽部17内的液体可以在凹槽部17中传送,但因该凹槽部17相对纵向和横向斜着形成。 Although introduced in said recess portion 17 may be transmitted to the liquid in the groove portion 17, but the recess portion 17 is formed obliquely relative to the longitudinal and transverse directions. 而在液体在上述凹槽部17传送后沿纵横两方向散开。 In the transfer liquid spread in the groove 17 in the vertical and horizontal portions of the two directions. 因在上述凹槽部17内加开有孔13,所以使要在凹槽部17传送的液体直接透过孔13被吸液芯3吸收。 Inga having a hole 13 in said recess portion 17, so that the liquid to be absorbed in the 3 transmission 17 directly from the groove portion 13 is wick hole. 由于液体在凹槽部17内传送,凹槽部17内的液体不容易饱和,从而可以进一步限制孔13及其周围的液体的滞留,可以使液体迅速地从孔部13供给吸液芯3。 Since the liquid 17 within the transfer, the liquid in the groove portion 17 is not easily saturated recess portion can be further restricted fluid retention and around the hole 13, the liquid can be quickly supplied to the wick 3 from the hole portion 13.

并且因上述凹槽部17环绕每个隆起部16形成。 And each of the ridge portion 16 is formed a recess portion 17 surrounded by the above-described. 而凹槽部17中的液体引导方向不会波及到多方向,并使液体不容易发生在纵向和横向的大范围内扩大的现象。 The liquid guide direction groove portion 17 is not spread to multiple directions, and the expansion of the liquid does not easily occur in the vertical and horizontal large-scale phenomenon.

另外,因隆起部16具有规定面积而且彼此独立,在其里面侧形成空间18,而使每个隆起部16受到皮肤的压力后可以柔软变形。 Further, because the raised portion 16 having a predetermined area and independently of each other, a space 18 is formed on its back side, each of the ridge portion 16 can be modified after pressure soft skin. 因此富有膨松感,不容易引起对穿用者皮肤的压迫感。 So rich fullness, not prone to oppressive feeling to the wearer's skin. 另外因每个隆起部16被凹槽部17区分而互相分立,所以隆起部16的变形不会传送给其它的隆起部16。 Further, because the groove portion 17 distinguishing each raised portion 16 and separate from each other, so that deformation of the raised portion 16 is not transmitted to other portions of the ridges 16. 从而可以使表面层10跟踪穿用者皮肤的凹凸形状进行变形,并且不仅柔软地跟踪表面层10的厚度方向的压力,还柔软地跟踪纵向和横向压力,所以具有很好的穿着感。 So that the surface layer 10 can track the wearer's skin uneven shape is deformed, and not only in the thickness direction flexibly tracking the pressure surface layer 10 is further flexibly tracking vertical and horizontal pressure, and they have good wearing feeling. 另外,因各隆起部16沿X方向和Y方向相互不同,而当穿用者皮肤的压力将隆起部16压坏或压倒时,相邻的隆起部也不容易互相重叠,从而不容易对皮肤产生压力刺激。 Further, because each of the raised portions 16 in the X and Y directions different from each other, and when the pressure is raised to the wearer's skin portion or crushing overwhelm 16 adjacent the raised portion is not easily overlap each other, so that the skin is not easily a pressure stimulation.

上述表面片11和里衬片12可以使用把通过梳理法成形的纤维网用热压花和热风接合成片状的空气泡沫无纺布,把连续的长纤维层叠后使纤维间接合成片的纺粘无纺布,使梳理法形成的纤维网的纤维之间通过水流交织的纺粘网无纺布等。 The topsheet 11 and the lining sheet 12 may be formed by using the carding method webs joined by hot embossing a sheet-like hot air foam and the nonwoven fabric, the fibers after continuous long sheet laminated synthetic fibers spun indirect spunbonded nonwoven fabric hydroentanglement bonding between the nonwoven fabric and the like by the carding method and a fiber web formed. 这些无纺布以膨松的且纤维密度低、在厚度方向富有弹性恢复力的气穿式无纺布为最优选,这种透气无纺布是将通过梳理法形成的纤维网,用热风吸入使纤维间接合起来而形成的。 The bulky nonwoven fabric and low in fiber density in the thickness direction of the elastic restoring force of the air-through nonwoven fabric is most preferable, which is air-permeable nonwoven fibrous web formed by the carding method, a hot air suction indirect together the fibers formed.

使用于无纺布材料的纤维可以使用外鞘部分的熔点比PE(聚乙烯)/PP(聚丙烯)、PE/PET、EVOH(聚乙烯乙二醇共聚体)/PET、PP/PP、PET(聚对苯二甲酸、乙二醇酯)/PET等芯部分融点低的树脂构成的芯鞘结构、偏芯芯鞘结构的复合刚性纤维或上述树脂组合的并置结构的复合合成纤维的热融性纤维。 The nonwoven material used in the fibers may be used than the melting point of the sheath portion PE (polyethylene) / PP (polypropylene), PE / PET, EVOH (polyethylene glycol copolymer) / PET, PP / PP, PET compound (polyethylene terephthalate, polyethylene terephthalate) core-sheath structure of low / PET core portion and the like of a resin melting point, eccentric core-sheath structure composite fiber or a rigid resin composition of the above-described structure of the synthetic fibers juxtaposed heat fusible fibers.

最好根据需要为了变成白色而使上述纤维中含有例如0.1~10%重量配比的二氧化钛等无机填充剂,由于含有上述无机填充剂而可使表面片11和里衬片12变成白色,从而能在视觉上遮盖被吸液芯3吸收的经血等液体的颜色。 To the best white into said fiber contains 0.1 to 10% by weight proportion of inorganic fillers such as titanium oxide as needed, because it contains the inorganic filler can be surface sheet 11 and the liner sheet 12 becomes white, so that it can cover the color is absorbed by the wick of a liquid such as menstrual blood visually.

上述表面片11和里衬片12的无纺布由上述疏水性合成纤维制成。 The topsheet 11 and the liner 12 is a nonwoven fabric sheet made of the above-described hydrophobic synthetic fibers. 也可以在上述疏水性合成纤维中混入粘胶人造丝、醋酸人造丝等再生纤维素纤维和天然纤维素纤维等亲水性纤维。 It may be mixed viscose rayon, acetate rayon and the like in the above-described hydrophobic synthetic fibers and regenerated cellulose fibers and other natural cellulosic fibers hydrophilic fibers.

或者,位于穿用者皮肤一侧的上述表面片11可以为疏水纤维为主体地构成的疏水性无纺布,也可以用上述疏水性纤维和上述亲水性纤维混合的无纺布片形成上述里衬片12。 Alternatively, the hydrophobic nonwoven fabric sheet is located above the surface of the wearer's skin side of the main body 11 may be made of hydrophobic fibers, a nonwoven fabric sheet can be used the hydrophobic fibers and the hydrophilic fibers forming the mixed lining piece 12. 或者,也可以对构成里衬片12的疏水性合成纤维进行涂敷亲水油剂等进行亲水处理。 Alternatively, the hydrophilic oil solution may be coated on the hydrophobic synthetic fibers, etc. constituting the lining sheet 12 of hydrophilic treatment. 这样一来,因使里衬片12的亲水性能比表面片11高,并设定亲水率梯度,而把落到表面片11上的液体中的没有透过孔13的那部分吸引到里衬片12中,从而可使其透过表面片11,由此可以减少表面层10的表面湿润度。 Thus, due to the hydrophilic properties of the specific surface so that the lining sheet 12 of the sheet 11 high, and set the ratio of hydrophilic gradient, and not attracted to the hole 13 through the portion of the liquid 11 falls on the surface of the sheet lining sheet 12, thereby making it permeable surface sheet 11, thereby reducing the wet surface of the surface layer 10.

另外,作为表面片11和里衬片12,在疏水性合成纤维中混合亲水纤维的情况下,为了在保持吸湿性能的同时不损害无纺布的弹性最好使上述亲水纤维采用2-30%的重量配比。 Further, as the surface sheet 11 and the lining sheet 12, in the case of hydrophobic synthetic fibers of hydrophilic fibers mixed in, in order not to damage the elastic nonwoven fabric while maintaining moisture absorption is preferable that the hydrophilic fibers using 2- 30% weight ratio.

作为表面片11的无纺布材料的特性保持膨松性和弹性是重要的,因此表面片11的厚度优选在0.3~2.0mm的范围内,最好在0.3~1.0mm的范围内,为了不产生纹理不均匀而最好使用纤度在1.1~4.4登尼尔范围和纤维织物面密度在20~150g/m2的无纺布。 As the surface of the material properties of the nonwoven fabric sheet 11 and the elastic retaining bulkiness is important, the thickness of the surface sheet 11 is preferably in the range of 0.3 ~ 2.0mm, preferably in the range of 0.3 ~ 1.0mm in order not texturing a non-uniform fineness is preferably used in the range of 1.1 to 4.4 denier and a fiber density of the nonwoven fabric surface of fabric 20 ~ 150g / m2 of. 另外为了得到膨松性和弹性而最好使在隆起部16形成孔13前的状态的无纺布在宽度为一英寸、夹头间距100mm,拉伸速度100mm/分的条件下拉伸时的纵向(Y方向)的拉断强度优选在6.8N以上,更优选的是11.7~24.5N的范围,而横向(X方向)的拉断强度优选在0.9N以上,更优选在1.4~2.5N的范围。 Further in order to obtain bulkiness and elasticity of the nonwoven fabric is preferred that the raised portion 16 is formed in a state before a hole 13 in one inch width, distance between chucks 100mm, when stretched under a tensile speed of 100mm / min. longitudinal direction (Y direction) tensile strength at break is preferably at least 6.8N, more preferably in the range of 11.7 ~ 24.5N, tensile breaking strength and lateral (X direction) is preferably at least 0.9N, more preferably 1.4 ~ 2.5N of range.
