Abstract

本发明提供一种防漏片。提供一种具有针对尿的良好的憎水性和针对软便的良好的疏油性的一次性吸收性物品。一次性尿布具有吸收要素(40)、透液性的表面片(50)以及防漏片(55)。防漏片具有由纤维的平均直径是0.5μm～10μm的无纺布构成的憎水层(56)。憎水层具有在纤维的表面附着有微粒组的憎水区域。微粒组具有：第1微粒，其平均粒径是1μm～20μm；以及第2微粒，其附着于第1微粒上，且平均粒径是5nm～100nm。

Description

防漏片
本申请是申请日为2017.12.19、申请号为201780084575.8、发明名称为“一次性吸收性物品”的申请的分案申请。
技术领域
本发明涉及一种具有防漏片的一次性吸收性物品。
背景技术
以往，公知有包括以疏水性表面涂敷进行了处理的无纺布的一次性吸收性物品(例如参照专利文献1)。
现有技术文献
专利文献
专利文献1：日本特表2012-518495
发明内容
在专利文献1的疏水性表面涂敷中含有至少两种有机硅聚合物。一般而言，有机硅(日文：シリコン)的表面张力(表面自由能)是16mN/m～30mN/m，水的表面张力是73mN/m，油的表面张力成为25mN/m～30mN/m。在此，具有如下特征：两者间的表面张力之差越大，憎水性越大(即，良好地疏水)。
因而，在专利文献1所公开的一次性吸收性物品中使用的无纺布针对尿具有良好的憎水性，但针对含有油分的软便不具有良好的疏油性。因此，在专利文献1的一次性吸收性物品中存在如下问题点：软便透过无纺布，软便渗出。
因此，本发明的目的在于提供一种具有针对尿的良好的憎水性和针对软便的良好的疏油性的一次性吸收性物品。

附图说明
图1是本实施方式的一次性尿布的展开俯视图。
图2是图1所示的A-A线的剖视图。
图3是示意性地表示防漏片的截面的剖视图。
图4是示意性地表示微粒组和纤维的构造的图。
具体实施方式
根据本说明书和附图的记载，至少明确以下的事项。
一种一次性吸收性物品，其具有：
相互正交的前后方向和宽度方向；
厚度方向，其向穿着者的肌肤相对面侧和非肌肤相对面侧延伸；
吸收要素；
透液性的表面片，其配置于比所述吸收要素靠所述肌肤相对面侧的位置；以及
防漏片，其配置于比所述吸收要素靠所述厚度方向的外侧的位置和比所述吸收要素靠所述宽度方向的外侧的位置中的至少任一者，该一次性吸收性物品的特征在于，
所述防漏片具有由纤维的平均直径是0.5μm～10μm的无纺布构成的憎水层，
所述憎水层具有在所述纤维的表面附着有微粒组的憎水区域，
所述微粒组具有：第1微粒，其平均粒径是1μm～20μm；以及第2微粒，其附着于所述第1微粒上，且平均粒径是5nm～100nm。
防漏片的憎水层由纤维的平均直径是0.5μm～10μm的无纺布构成。纤维的平均直径是0.5μm～10μm，从而纤维易于致密地配置，尿、软便难以经由纤维间的空隙透过。另外，憎水层具有在纤维的表面附着有微粒组的憎水区域。微粒组具有：第1微粒，其平均粒径是1μm～20μm；以及第2微粒，其附着于第1微粒上，且平均粒径是5nm～100nm。因而，在憎水层的纤维的表面上形成有由第1微粒构成的凹凸形状，且在该第1微粒上形成有由第2微粒构成的凹凸形状。利用粒径不同的微粒形成两级凹凸形状，欲在纤维间通过的尿和软便与附着于纤维的表面的微粒组接触，难以通过微粒组纤维间的空隙。因而，能够利用防漏片发挥针对尿的良好的憎水性和针对软便的良好的疏油性。
在该吸收性物品中，期望的是，
所述防漏片具有配置于比所述憎水层靠所述厚度方向的外侧的位置的保护层，
所述保护层由纤维的平均直径是10μm以上的无纺布构成。
根据这样的吸收性物品，能够利用保护层保护憎水层的厚度方向的外侧的面，易于维持憎水层内的微粒组的形状。因而，即使是在流通时、使用时防漏片的表面被蹭到的情况下，也能够维持憎水层的憎水性能，发挥针对尿的良好的憎水性和针对软便的良好的疏油性。另外，构成保护层的纤维的平均粒径是10μm以上，比憎水层的纤维的平均粒径高。因而，保护层的纤维比憎水层的纤维易于稀疏地配置。保护层的缓冲性比憎水层的缓冲性高，易于利用保护层保护憎水层的微粒组的构造。另外，保护层的纤维比憎水层的纤维稀疏地配置，因此，易于引入尿、软便。根据如此构成的防漏片，能够利用保护层迅速地引入尿、软便，利用憎水层使所引入的体液难以透过，且使所引入的体液保持在憎水层内。能够提高体液的引入性，同时抑制体液的泄漏，能够提高穿戴感。
在该吸收性物品中，期望的是，
所述憎水区域的至少一部分配置于在所述厚度方向上将所述憎水层三等分而位于所述厚度方向的中央的中央区域。
根据这样的吸收性物品，能够利用比中央区域靠厚度方向的外侧的区域保护中央区域的厚度方向的外侧的面，易于维持中央区域内的微粒组的形状。因而，即使是在流通时、使用时憎水层的表面被蹭到的情况下，也能够维持憎水层的中央区域的憎水性能，发挥针对尿的良好的憎水性和针对软便的良好的疏油性。
在该吸收性物品中，
在所述表面片和配置于比所述吸收要素靠非肌肤相对面侧的位置的背面片中的至少任一者设有凹凸区域，该凹凸区域具有向所述肌肤相对面侧突出的凸部和设于所述凸部之间的凹部，
所述凹凸区域在所述厚度方向上与所述憎水区域重叠地配置。
根据这样的吸收性物品，在外力作用到吸收性物品之际，凹凸区域的凹部和凹部变形，能够抑制该外力向防漏片传递。凹凸区域以与憎水区域重叠的方式配置，因此，易于维持憎水区域的微粒组的形状。因而，能够利用防漏片发挥针对尿的良好的憎水性和针对软便的良好的疏油性。
在该吸收性物品中，期望的是，
设有所述凹凸区域的所述表面片和所述背面片以非连续的方式与所述防漏片接合。
根据这样的吸收性物品，设有如下部分：设有凹凸区域的片与防漏片接合起来的部分；设有凹凸区域的片与防漏片未接合的部分。设有凹凸区域的片与防漏片未接合的部分比接合起来的部分易于变形。因而，在外力作用到吸收性物品之际，能够利用设有凹凸区域的片与防漏片未接合的部分吸收外力，抑制该外力向防漏片传递。因而，易于维持憎水层的微粒组的形状，能够发挥针对尿的良好的憎水性和针对软便的良好的疏油性。
在该吸收性物品中，
所述憎水区域在比所述吸收要素靠所述非肌肤相对面侧的位置处以覆盖所述吸收要素的整个区域的方式配置为佳。
根据这样的吸收性物品，憎水区域以覆盖吸收要素的非肌肤相对面侧的整个面的方式配置，能够利用该憎水区域发挥吸收要素的非肌肤相对面侧的憎水性。能够提供一种利用防漏片确保吸收要素的非肌肤相对面侧的憎水性且不具有背面片的吸收性物品。一般而言，吸收性物品的背面片由膜构成，与由无纺布构成的防漏片相比较，柔软性较低，有时在变形时产生不适感或产生磨擦的声音。根据不具有背面片的吸收性物品，能够减少变形时的不适感、变形时的声音，提高穿戴感。
在该吸收性物品中，
所述憎水区域在比所述吸收要素靠所述非肌肤相对面侧的位置处以覆盖吸收要素的位于比所述一次性吸收性物品的所述前后方向的中心靠后侧的部分的方式配置。
比前后方向的中心靠后侧的区域是与比身体的下裆靠后侧的位置抵接且便排出的区域。根据这样的吸收性物品，憎水区域以覆盖吸收要素的位于比前后方向的中心靠后侧的部分方式配置，能够利用该憎水区域发挥针对便的防漏性。能够提供一种利用防漏片确保吸收要素的非肌肤相对面侧的防漏性且不具有背面片的吸收性物品。一般而言，背面片由膜构成，与由无纺布构成的防漏片相比较，柔软性较低，有时在变形时产生不适感或产生磨擦的声音。根据不具有背面片的吸收性物品，能够减少变形时的不适感、变形时的声音，提高穿戴感。
在该吸收性物品中，期望的是，
所述憎水层的所述微粒组的克重比所述保护层的所述微粒组的克重高。
根据这样的吸收性物品，憎水层的微粒组的克重较高，因此，在由保护层保护的憎水层内维持很多微粒组的形状，该憎水层具有良好的憎水性和疏油性。
在该吸收性物品中，期望的是，
所述憎水层中的所述纤维的纤维间距离是50μm以下。
根据这样的吸收性物品，尿、软便难以经由纤维间的空隙透过。因而，能够利用防漏片提高防漏性。
在该吸收性物品中，期望的是，
所述憎水层相对于水和油的接触角比135°大。
根据这样的吸收性物品，憎水层相对于水和油的接触角比135°大，具有良好的憎水性和疏油性。
在该吸收性物品中，期望的是，
所述憎水层的表面张力是30mN/m以下。
根据这样的吸收性物品，憎水层的表面张力与水的表面张力之差较大，且憎水层的表面张力与油的表面张力之差较大，因此，能够针对尿和软便发挥良好的防漏性。
在该吸收性物品中，期望的是，
所述防漏片构成立体褶裥和腿部褶裥中的至少任一者。
根据这样的吸收性物品，不利用具有防漏性的膜构成立体褶裥和腿部褶裥，而是利用无纺布构成立体褶裥和腿部褶裥，能够利用该无纺布发挥针对尿、软便的防漏性。立体褶裥和腿部褶裥以与穿着者的肌肤接触的方式配置，通过由无纺布构成，能够缓和与肌肤的触碰，提高穿着者的穿戴感。
＝＝＝关于本实施方式的一次性吸收性物品＝＝＝
接着，一边参照附图一边对作为本发明的一次性吸收性物品的一次性尿布10的实施方式进行说明。此外，本发明的一次性吸收性物品并不限定于一次性尿布，是包括能够安装固定于内衣或尿布的吸收垫的一次性吸收性物品。另外，在以下的附图的记载中，对相同或类似的部分标注相同或类似的附图标记。不过，附图是示意性的，应该留意各尺寸的比率等与现实的各尺寸的比率等不同。因而，具体的尺寸等应该参考以下的说明而判断。另外，在附图相互间也可能包含彼此的尺寸的关系、比率不同的部分。
(1)一次性尿布的整体概略结构
图1是本实施方式的一次性尿布10的展开俯视图。图1所示的展开俯视图是使立体褶裥的伸缩部分伸长到构成一次性尿布的表面片50、侧片70等没有形成褶皱的状态的伸长状态的图。图2是沿着图1所示的A-A线的剖视图。
一次性尿布10具有前腰围区域20、下裆区域25以及后腰围区域30。前腰围区域20是与穿着者的前腰围部(腹部分)接触的部分。另外，后腰围区域30是与穿着者的后腰围部(背部分)接触的部分。下裆区域25位于前腰围区域20与后腰围区域30之间。此外，在本实施方式中，将从前腰围区域20朝向后腰围区域30的方向称为前后方向L，将与前后方向L正交的方向称为宽度方向W，将向穿着者的肌肤相对面侧T1和非肌肤相对面侧T2延伸的方向称为厚度方向T。
一次性尿布10具有吸收要素40。吸收要素40跨下裆区域25，且向前腰围区域20和后腰围区域30中的至少任一者延伸。本实施方式的吸收要素40跨前腰围区域20、下裆区域25以及后腰围区域30地配置。吸收要素40具有含有浆粕和SAP等吸收材料的吸收芯。
在吸收要素40的肌肤相对面侧T1设有透液性的表面片50。表面片50构成一次性尿布10的肌肤抵接面，与穿着者接触。表面片50跨前腰围区域20、下裆区域25以及后腰围区域30地配置。表面片50具有纤维，具体而言，能够由无纺布构成。
表面片50具有引入区域R13。引入区域R13是与周围的区域相比软便向吸收要素侧的引入性较高的区域。具体而言，引入区域R13能够例示形成有沿着厚度方向T贯通的开口的区域、交替地形成有向肌肤相对面侧突出的凸部和设于凸部之间的凹部的区域。具有开口的引入区域R13能够将表面片的肌肤相对面上的软便经由开口向表面片的非肌肤相对面侧引入。另外，形成有凸部和凹部的引入区域利用凸部间的凹部保持软便，能够将凹部内的软便向非肌肤相对面侧迅速地引导。另外，凸部形成为格子状的引入区域利用格子状的凸部包围凹部，能够抑制软便向周围扩散，将凹部内的软便向非肌肤相对面侧迅速地引导。该引入区域以在厚度方向上与后述的憎水区域重叠的方式配置。引入区域配置于比吸收性物品的前后方向的中心靠后侧的位置，更详细而言，配置于后腰围区域。引入区域设于便排出的区域。
在吸收要素40的非肌肤相对面侧配置有防漏片55。防漏片55构成一次性尿布的非肌肤相对面。防漏片55具有憎水性和疏油性。在后述中详细地说明防漏片55的结构。
在一次性尿布10的比宽度方向的中心靠宽度方向的两外侧的位置配置有一对立体褶裥80。立体褶裥80由侧片70和作为弹性构件的侧弹性构件71构成。
侧片70覆盖表面片的外侧缘。在侧片70的内侧缘侧配置有沿着前后方向伸缩的侧弹性构件71。立体褶裥80具有可利用沿着前后方向伸缩的侧弹性构件71向穿着者侧立起的立起部。立体褶裥80在吸收要素40的外侧缘形成向肌肤侧立起的壁，防止排泄物的侧漏。
在一次性尿布10的外侧缘形成有配置于穿着者的腿围的腿部褶裥90。腿部褶裥90由侧片70、腿部弹性构件92、防漏片55构成。腿部弹性构件92以沿着前后方向伸长了的状态配置于侧片70与防漏片55之间。腿部褶裥90在吸收要素40的外侧缘与腿围密合，防止排泄物的侧漏。
(2)防漏片的详细结构
接下来，对防漏片55进行说明。图3是示意性地表示防漏片的剖视图。防漏片55配置于比吸收要素40靠厚度方向T的外侧即非肌肤相对面侧T2的位置。此外，防漏片55既可以配置于比吸收要素40靠肌肤相对面侧T1的位置，也可以配置于比吸收要素40靠宽度方向W的外侧的位置。
如图3所示，防漏片55由憎水层56和配置在憎水层56的肌肤相对面侧T1和非肌肤相对面侧T2的保护层57这3层构成。防漏片55由SMS无纺布构成，憎水层56由熔喷无纺布构成，保护层57由纺粘无纺布构成。
憎水层56位于防漏片55的厚度方向T上的中央。憎水层56的纤维由含有聚丙烯、聚对苯二甲酸乙二醇酯中的至少任一者的纤维构成。憎水层56的纤维的克重是12gsm，纤维的平均直径是0.5μm～10μm。憎水层56的纤维间距离是50μm以下。
憎水层56具有在纤维的表面附着有微粒组60的憎水区域。本实施方式的憎水区域在俯视时设于憎水层56的整个区域。此外，优选憎水区域设于与吸收要素40重叠的区域，既可以不设于一次性尿布10的外侧缘，也可以不设于一次性尿布10的前端缘和后端缘。另外，憎水区域也可以在比吸收要素40靠非肌肤相对面侧T2的位置处以覆盖吸收要素40的位于比吸收性物品的前后方向的中心靠后侧的位置的部分的方式配置。憎水区域也可以配置于与表面片50的引入区域R13重叠的区域。
如图4所示，微粒组60具有：第1微粒61，其平均粒径是1μm～20μm；以及第2微粒62，其附着于第1微粒61上，且平均粒径是5nm～100nm。作为第1微粒61，能够例示由烯烃系树脂构成的树脂粒子。另外，作为第2微粒62，能够例示氧化物微粒。在第1微粒61的表面分散附着有第2微粒。在构成憎水层56的纤维的表面形成有由第1微粒61构成的微小的凹凸，在该微小的凹凸的表面还形成有由第2微粒62构成的微细的凹凸。利用这样的表面形状提高表面的憎水性和疏油性。
此外，能够利用扫描型电子显微镜(FE-SEM)实施微粒的平均粒径的测定，在扫描型电子显微镜的分辨率较低的情况下，也可以同时使用透过型电子显微镜等其他电子显微镜而实施。具体而言，在粒子形状是球状的情况下是其直径，在非球状的情况下，将其最长径与最短径的平均值视作直径，将通过由扫描型电子显微镜等进行的观察而任意选择的20个粒子的直径的平均值设为一次粒子平均径。
使第1微粒61和第2微粒62附着于纤维的表面的方法并没有特别限定。例如，能够通过将使第1微粒61和第2微粒62分散于溶剂中而成的涂料涂敷于无纺布并进行干燥，从而将第1微粒61形成为膜状，并且，使第2微粒62分散附着于该膜状的表面。
保护层57位于憎水层56的厚度方向T上的两外侧。保护层57的纤维由含有聚丙烯、聚对苯二甲酸乙二醇酯中的至少任一者的纤维构成。保护层57的纤维的克重是6gsm，纤维的平均直径是12μm～22μm。优选的是，保护层57的纤维的平均直径比10μm大，且比憎水层56的纤维的平均直径大。在构成憎水层56的纤维的表面也附着有微粒组60。微粒组60的结构与憎水层56的微粒组的结构同样。
憎水层56的微粒组60的克重比保护层57的微粒组60的克重高。本实施方式的憎水层56的微粒组60的克重是2gsm，保护层57的微粒组的克重是1gsm。
优选憎水层56的表面张力和包括保护层57在内的防漏片55的表面张力分别是30mN/m以下，更优选是20mN/m以下为佳。此外，能够使用Automatic Surface TensiometerCBVP-Z(协和界面科学株式会社制)，在25℃的条件下测定表面张力。另外，优选憎水层56相对于水和油的接触角比135°大，包括保护层57在内的防漏片55的接触角也可以比135°大。此外，对于接触角，能够将配置于非肌肤相对面侧的面设为试验面，使用接触角测定装置(固液界面分析装置“Drop Master 300”协和界面化学会社制)，测定相对于纯水的接触角和相对于油的接触角。
(3)其他实施方式
上述的实施方式的防漏片具有保护层，但本发明的防漏片也可以不具有保护层。在不具有保护层的防漏片中，优选的是，憎水区域的至少一部分配置于在厚度方向上将憎水层三等分而位于厚度方向的中央的中央区域。
吸收性物品也可以在防漏片的非肌肤相对面侧具有背面片。背面片包括吸收性物品的非肌肤相对面，位于吸收要素和防漏片的非肌肤相对面侧。背面片也可以设有凹凸区域。另外，设有凹凸区域的背面片以非连续的方式与防漏片接合为佳。具体而言，在防漏片与背面片之间交替地配置有相互接合的区域和未相互接合的区域为佳。另外，在设有凹凸区域的表面片和防漏片在厚度方向上重叠的结构中，表面片和防漏片非连续地接合为佳。
如上述这样，通过本发明的实施方式公开了本发明的内容，但不应该理解为构成该公开的一部分的论述和附图用于限定本发明。根据该公开，各种代替实施方式、实施例以及运用技术对本领域技术人员来说是显而易见的。因而，本发明的保护范围仅由根据上述的说明合理概括出的权利要求书的特定技术特征确定。
