Description

具有通道的吸收性制品及用于所述吸收性制品的相关方法
技术领域
本申请总体涉及一次性吸收性产品或制品。更具体地，本申请涉及具有吸收性芯体设计和包括通道的构型的垫料。
背景技术
采用吸收性制品以收集和/或吸收体液排放物，诸如，血液、月经、尿、水质体液、粘液、以及细胞残骸。吸收性制品包括例如一次性尿布、成人失禁垫、卫生棉、局部衬垫等等，它们一般由婴儿和/或成人与衣服一起穿着且紧靠身体表面布置。吸收性制品也可以是适于与患者寝具一起使用的垫料，例如，放置在患者身下的一次性垫料。
发明内容
在此公开的制品通过利用构造为吸收流失的多层顶部片材和/或吸收性芯体构型而减少泄漏，并且通过协助流体排放物的分散而提供改进的吸收性能。
根据本申请的吸收性制品包括流体可渗透顶部片材、流体不可渗透底部片材、以及定位在流体可渗透顶部片材和流体不可渗透底部片材之间的吸收性芯体。吸收性芯体是包括多个隔开的超强吸收性区段的非连续层，所述多个隔开的超强吸收性区段在其间限定通道。通道可以沿吸收性芯体的长度直线地延伸。在另外的实施方式中，所述通道沿吸收性芯体的整个纵向和/或横向长度延伸。
超强吸收性区段具有包括超强吸收性聚合物颗粒的第一分布的内区域和包括超强吸收性聚合物颗粒的第二分布的外区域。超强吸收性聚合物颗粒的第一分布可以比超强吸收性聚合物颗粒的第二分布大。内区域可以包括大约70％的超强吸收性聚合物颗粒且外区域包括大约30％的超强吸收性聚合物颗粒。在一些实施方式中，内外区域沿吸收性芯体的纵向长度直线地延伸且排列于通道，其中内区域靠近通道。在一些其他实施方式中，内区域围绕通道径向延伸且外区域围绕内区域径向延伸。
吸收性制品可以包括附加层。吸收性制品可以包括布置在顶部片材和吸收性芯体之间的非纺织条、和/或布置在底部片材和吸收性芯体之间的吸收性层。吸收性层可以延伸遍及吸收性芯体的整个长度和宽度，同时在一些实施方式中，吸收性层可以仅仅覆盖由吸收性芯体形成的通道的长度和宽度。吸收性层可以包括穿过吸收性层的均匀分布的绒毛纤维，或替换性地，吸收性层可以具有包括绒毛纤维的第一分布的内区域和包括绒毛纤维的第二分布的外区域。绒毛纤维的第一分布可以比绒毛纤维的第二分布大。内区域可以包括大约60％的绒毛纤维且外区域包括大约40％的绒毛纤维。
根据本申请的另一方面，吸收性制品包括流体可渗透顶部片材、流体不可渗透底部片材、以及定位在流体可渗透顶部片材和流体不可渗透底部片材之间的吸收性芯体。吸收性芯体是由超强吸收性材料制造的连续层，并且在吸收性芯体的中央部分周围限定通道。通道从顶部片材延伸到底部片材。吸收性芯体可以包括围绕通道延伸的内区域和围绕内区域延伸的外区域。内区域可以包括比外区域高的超强吸收性材料分布。
本申请的一个或多个方面涉及吸收性制品，其包括流体可渗透顶部片材、流体不可渗透底部片材、以及定位在顶部片材和底部片材之间的吸收性芯体，所述吸收性芯体包括多个超强吸收性区段，所述多个超强吸收性区段在其间限定至少一个通道，在一些构造中，所述至少一个通道尺寸定为沿吸收性芯体的长度直线地延伸。所述至少一个通道可以尺寸定为沿吸收性芯体的纵向长度和横向长度延伸。所述多个超强吸收性区段可以设置为在其间限定通道网格。吸收性芯体的超强吸收性区段可以包括超强吸收性聚合物颗粒。所述多个超强吸收性区段中的至少一个可以限定包括第一含量的超强吸收性聚合物颗粒的第一区域，并且所述多个超强吸收性区段中的至少另一个限定包括第二含量的超强吸收性聚合物颗粒的第二区域，超强吸收性聚合物颗粒的第一含量比超强吸收性聚合物颗粒的第二含量大。第一区域可以包括大约至少大约70wt％的超强吸收性聚合物颗粒和小于大约30wt％的绒毛纤维。第一区域和第二区域可以尺寸定为沿吸收性芯体的纵向长度直线地延伸。吸收性制品还可以包括布置在底部片材和吸收性芯体之间的吸收性材料的层。吸收性层包括绒毛纤维的基体。所述至少一个通道可以具有大约0.1mm到大约10mm的宽度。所述至少一个通道可以包括具有第一宽度的第一部分、具有第二宽度的第二部分、以及在第一和第二部分之间的第三部分，第三部分具有比第一和第二宽度大的第三宽度。第一宽度可以与第二宽度大约相同。在其间限定所述至少一个通道的所述多个吸收性区段可以限定沿吸收性芯体的长度延伸的纵向通道和至少一个横向通道，所述至少一个横向通道中的每个沿吸收性芯体的宽度延伸。纵向通道可以在吸收性芯体的大约中央处布置，并且所述至少一个横向通道中的每个流体连接到纵向通道。吸收性制品还可以包括布置在顶部片材和吸收性芯体之间的非纺织条。
本申请的一个或多个方面涉及制造吸收性制品的方法。所述方法可以包括提供流体可渗透顶部片材、提供流体不可渗透底部片材、以及将吸收性芯体定位在顶部片材和底部片材之间，所述吸收性芯体包括多个超强吸收性区段，所述多个超强吸收性区段在其间限定至少一个通道。定位吸收性芯体的步骤可以包括提供包括超强吸收性颗粒和绒毛纤维的混合物的所述多个超强吸收性区段。

具体实施方式
以下讨论包括对根据本申请原理的本公开的吸收性制品的说明。吸收性制品可以包括基底，流体排放物(例如，液体排泄物)可能被施加且吸收到所述基底上和基底内。为了讨论的目的，将就病人护理垫料方面讨论吸收性制品；然而，本公开的吸收性制品可以是任何吸收性产品，诸如，例如，幼儿尿布和训练裤、女性月经垫、成人失禁产品、宠物训练垫、以及用以吸收流体的其他一次性产品。吸收性制品典型地包括三层设计，所述三层设计具有用于接合身体表面的流体可渗透顶部片材、用于防止流体通过所述制品泄漏的流体不可渗透背部片材、以及被支撑在流体可渗透顶部片材和流体不可渗透背部片材之间的吸收性芯体。吸收性芯体通常包括面向身体表面的液体保持材料。吸收性芯体可以包括用于获取和存储流体排放物的松散成形的纤维素纤维、超强吸收性纤维、超强吸收性颗粒、或呈连续或压印模式的它们的组合物。流体排放物泄漏可能由于吸收性芯体的过度饱和和/或由于淤积流体流失而产生。例如，在流体排放(诸如，排泄)期间，沉积在顶部片材上的尿在尿渗入吸收性芯体之前淤积是常见的。如果淤积发生，则尿将不被吸收且可能发生流体流失，从而导致从吸收性制品过早泄漏。
现在将参考附图详细地说明本公开的吸收性制品的实施方式，其中，同样的附图标记指代多个附图中的每个中的类似或相同的元件。在讨论中，术语"近侧"或"身体侧"将指示吸收性制品的更靠近使用者的部分，而术语"远侧"或"固定部件侧"将指示吸收性制品的远离使用者的部分。术语"身体侧"不应该被解释为必然地指示与使用者的身体接触，而是简单地意味着面向使用者的身体的一侧，不管吸收性制品是否实际上被使用、且不管是否存在或可能有在吸收性制品和使用者的身体之间的中间层。同样地，术语"固定部件侧"不应该被解释为意味着被贴到物件(例如衣服、寝具、床、椅子、轮椅)，而是简单地意味着背向使用者的身体的一侧，并且因此朝向使用者正在利用的任何固定部件，不管是否存在或可能有在吸收性制品和固定部件之间的中间层。
现在参照视图，其中，在多个附图中自始至终相同的构件被相同的附图标记指代，图1示出垫料10的一部分的横截面，作为根据本申请的吸收性制品的实施例，所述垫料包括顶部片材20、底部或背部片材30、以及布置在顶部片材20和底部片材30之间的吸收性芯体40。由为吸收性制品选定的设计和用途来决定顶部片材、底部片材、以及吸收性芯体的尺寸和形状。底部片材30的边缘部分可以在顶部片材20的一部分之上折叠以形成不透流体的折叠式边缘密封。
顶部片材20是流体可渗透层，以允许液体(例如，月经或尿)快速地渗过顶部片材的厚度。顶部片材20对于接触而言可以是柔顺和/或柔软的，以使得顶部片材不会刺激皮肤。顶部片材20可以由大范围材料制造，诸如，纺织和非纺织材料，例如，纤维的非纺织网；聚合材料，诸如具有孔的热塑膜、具有孔的塑料膜、以及液压成形的热塑膜；多孔泡沫；网状泡沫；网状热塑膜；以及热塑沙罩。可以用以构造纺织和非纺织材料的合适纤维例如包括例如木或棉纤维的天然纤维、例如聚合纤维(诸如，聚酯、聚丙烯、或聚乙烯纤维)的合成纤维、以及自然和合成纤维的组合物。在顶部片材20是非纺织网的实施方式中，所述网可以被纺粘、梳理、湿法铺置、熔喷、液压缠绕、或利用适于形成非纺织网的任何方法形成。
底部片材30可以是流体不可渗透层，以防止吸收且容纳在吸收性芯体40中的液体浸湿接触垫料的物件，诸如但并非限于内衣、裤子、睡衣、以及床单。底部片材30可以是：纺织材料；非纺织材料；液体不可渗透织物；纤维素膜；聚合膜，诸如聚乙烯或聚丙烯的热塑膜；防流体浸透纸；复合材料，例如，多层(诸如，覆膜)非纺织材料；或它们的组合物。底部片材30或至少其部分可以被压印或可以被糙面精整以提供类布料外观、和/或被上色以用于容易识别。底部片材30可以是透气的，以允许至少一些蒸气从吸收性芯体40离开或经过，同时防止流体排放物从吸收性芯体穿过。
底部片材30可以是可附连的、或配置成可移除地附连到物件或固定部件(未明确示出)，诸如内衣或另一件衣物、椅子、床或寝具、轮椅或患者可能使用一次性吸收性垫料所需的任何其他合适的固定部件。底部片材30可以包括一个或多个附连装置(未示出)，诸如，例如，一个或多个粘附块或粘附条、一个或多个钩环型连接器、一个或多个附连系带、一个或多个夹具连接器、它们的组合物、或用于将垫料10保持在物件或固定部件上的其他合适的连接器。附连装置(未示出)可以被贴到底部片材30的固定部件侧32，并且可以沿垫料10的一部分或整个长度和/或宽度延伸。
吸收性芯体40典型地包括由示例性吸收性材料制成的流体吸收材料或合成物，诸如但并非限于：泡沫；非纺织型复合织物；水凝胶；纤维素织物；超强吸收性聚合物；纺织织物；棉纸，纸；固有亲水性泡沫，例如，粘胶泡沫；自然或合成泡沫型聚合材料，例如，聚氨酯、聚醚、或已经被赋予亲水性或快速可湿性的苯乙烯/聚丁橡胶泡沫；粉碎型木质纸浆；任何等级的棉绒和棉木；人造丝纤维；原棉；漂白或未漂白绉纱棉纸；以及它们的组合物和合成物。
吸收性芯体40的厚度可以变化而包括较厚和/或较薄区域，从而优化吸收性制品的性能。
吸收性芯体40可以包括木纤维或木浆绒毛的含纤维基体。在一些实施方式中，吸收性芯体40包括绒毛纤维的含纤维基体，超强吸收性聚合物(SAP)颗粒分散在所述含纤维基体中或所述含纤维基体上。SAP颗粒可以以均匀的方式或以穿过吸收性芯体形成SAP颗粒的分布梯度的方式连续地或非连续地穿过吸收性芯体40分布。
现在结合图1A参照图1B和1C，吸收性芯体40示例性地示出为在垫料10的大约中央布置(相对于底部片材30示出)，并且由多个隔开的超强吸收性区段50构成，所述多个隔开的超强吸收性区段在其间限定通道42。超强吸收性区段50包括SAP颗粒。通道42允许流体排放物被吸收性芯体40的排列的超强吸收性区段50吸收，同时也防止流体排放物流到垫料10的外侧。通道42沿纵向轴线"A"(例如，沿机器方向)、沿整个吸收性芯体的长度40延伸。第一超强吸收性区段50a和第二超强吸收性区段50b定位在通道42的对立侧上，以使得纵向延伸侧52a和52b限定通道42的宽度"W"。通道42的宽度"W"是可以是大约0.1mm到大约10mm，并且在另外的实施方式中，从大约0.25mm到大约8mm，并且在一些实施方式中，从大约1mm到大约5mm。通道42也包括整体延伸穿过吸收性芯体40的高度"H"。替换性地，通道42的高度"H"可以延伸穿过仅仅吸收性芯体40的一部分，如以下将进一步详细描述的。通道42的宽度"W"和高度"H"可以依据使用吸收性制品的应用变化。
第一和第二超强吸收性区段50a和50b包括邻近于通道42定位的内区域54，所述内区域包括比外区域56高的SAP颗粒分布。第一和第二超强吸收性区段50a和50b的内区域54分别包括相对于吸收性制品中的SAP总量的至少一半(如果不是SAP颗粒的大部分)。内区域54可以包括SAP颗粒的大约50％到大约90％，并且在一些实施方式中，SAP颗粒的大约70％在超强吸收性区段50的内区域54中分布。
虽然第一和第二超强吸收性区段的内外区域在图1B中示出为沿吸收性芯体40的长度直线地延伸，但是替换性地，如图1D所示，内区域54'可以在超强吸收性区段50的中央部分中提供，同时外区域56'围绕内区域的周边提供以形成径向分布模式。
界面51(图1B中以虚线示出)或界间(interphase)53(图1D中以虚线示出)可以存在于超强吸收性区段的内外区域之间。在此使用的术语"界面"意味着一表面，所述表面形成位于两个区域之间(在这种情况下例如内外区域之间)的边界。所述界面提供从一个区域到另一区域的急剧过渡或边界。在此使用的术语"界间"意味着在内外区域之间的体积特征之间的区域。界间提供从一个区域到另一区域的逐渐过渡或梯度。
使用中，垫料10被放置在使用者的正下方，以使得垫料10的中央定位成接收来自使用者的流体排放物。当垫料10接收来自使用者的流体排放物(诸如，流体排泄物)时，大部分流体穿过顶部片材20且被吸收性芯体40吸收。超强吸收性区段50和通道42的排列、以及SAP颗粒在超强吸收性区段50内的分布模式允许流体排放物快速迁移和/或芯吸到吸收性芯体40中。此外，通道42可以允许垫料10围绕其中央容易折叠。垫料典型地在一次排泄之后被丢弃。
图2A和2B示出根据本申请的垫料110的另一实施方式。垫料110包括顶部片材(未示出)、底部片材130、以及布置在顶部片材和底部片材之间的吸收性芯体140。图2A的垫料类似于图1B和1D的垫料，并且将仅仅对于它们之间的不同之处进行描述。
吸收性芯体140包括布置在超强吸收性区段150和底部片材130之间的吸收性层160。因此，通道142的高度"H"仅仅沿吸收性芯体的一部分延伸，如图2B所示，沿吸收性芯体140的大部分延伸。
吸收性层160包括绒毛纤维的基体。吸收性层160的内区域162包括比外区域164多的绒毛纤维分布。内区域162可以包括大约60％的绒毛纤维而外区域包括大约40％的绒毛纤维。内外区域162和164可以以沿纵向轴线"A"延伸的纵向模式提供(如所示)或可以以如以上相对于图1D的超强吸收性区段所述的径向模式提供。与上述超强吸收性区段一样，界面或界间可以存在于吸收性层160的内外区域162和164之间。
图3示出吸收性制品210的实施方式包括顶部片材(未示出)、底部片材230、以及吸收性芯体240，所述吸收性芯体包括多个连续超强吸收性区段250，所述多个连续超强吸收性区段限定沿纵向轴线"A"延伸的多个通道242。超强吸收性区段250、并且因此通道242平行或基本平行于彼此地设置或布置，并且可以穿过吸收性芯体240均匀地隔开。在超强吸收性区段250之间的间隔可以变化以限定变化宽度的通道。超强吸收性区段250均可以包括内区域254和外区域256，内区域254包括与在外区域256中不同(例如，更大)的相对比率的SAP颗粒。内区域254可以包括大约70％的SAP颗粒且外区域包括大约30％的SAP颗粒。在一些实施方式中，SAP颗粒从内区域254延伸到外区域256的外边缘258，以使得内区域254包括大约70％的SAP颗粒，外区域256包括大约30％的SAP颗粒，其中10％的SAP颗粒围绕外边缘258分布。
图4示出吸收性制品310包括可选的顶部片材(未示出)、底部片材330、以及以类网格模式相继隔开的多个超强吸收性区段350，由此限定沿纵向轴线"A"延伸的第一通道342a和沿纵向轴线"B"横向延伸的第二通道342b。第一和第二通道342a和342b在吸收性芯体340的大约中央交叉。超强吸收性区段350均包括内区域354，所述内区域包括比外区域356高比率的SAP颗粒。内区域354可以包括大约70的％SAP颗粒且外区域356包括大约30％的SAP颗粒。在一些实施方式中，SAP颗粒从内区域354延伸到外区域356的外边缘358，以使得内区域354包括大约70％的SAP颗粒，外区域356包括大约30％的SAP颗粒，其中10％的SAP颗粒围绕外边缘358分布。
替换性地，如在图5中示例性所示，吸收性制品310'可以在超强吸收性区段350的大约中央部分处具有带有内区域354'的芯体340，而外区域356'可以围绕内区域周边提供以形成SAP颗粒的径向分布模式。
通道442无需延伸吸收性芯体440的整个长度，而是可以在吸收性芯体440的大约中央部分处至少局部地定位。如图6所示，通道442可以限定在形成吸收性芯体的单一超强吸收性区段450内，或替换性地，如虚线所示，两个超强吸收性区段可以形成通道442。超强吸收性区段450可以包括内区域454和外区域456。
所述构造可以包括一个或多个附加层，诸如：例如，配置成管理和/或分配来自使用者的流体排放物的涌入的获取、吸入、或单向层；附连层；或其他合适的层，包括但并非限于传递层、芯吸层、存储层、流体处理层、再湿屏障、以及用于增强吸收性制品的性能和/或舒适性的其他层。
在根据本申请的一个或多个方面的一些实施方式中，非纺织条70可以放置在垫料10'的顶部片材20和吸收性芯体40之间，以覆盖通道42，由此形成防止累积SAP颗粒迁移的更好屏障，如图7所示。绒毛层80可以被施加到底部片材30，从而覆盖通道42的长度和宽度，因此形成防止流体排放物迁移出垫料10"的屏障，如图8所示。任何附加层可以通过粘附剂(诸如，热熔)或通过其他技术固定地紧固，所述其他技术例如包括且不限于超声结合、热压密封、以及热风刀结合。
虽然以上说明包含许多特例，但是这些特例不应该被解读为对本申请范围的限制，而是仅仅作为本发明的实施方式的举例。可以构思的是，在不偏离于本申请的范围的情况下结合一个示例性实施方式示出或描述的元件和特征可以与另一示例性实施方式的元件和特征结合，并且这些修改和变化也旨在包括在本申请的范围内。例如，根据这些修改和变化的一个或多个方面，吸收性制品可以包括流体可渗透顶部片材、流体不可渗透底部片材、以及定位在顶部片材和底部片材之间的非连续吸收性芯体，其中，吸收性芯体限定高度且包括多个超强吸收性区段，所述多个超强吸收性区段在其间限定至少一个通道，并且其中，所述多个超强吸收性区段中的至少一个限定第一区域和第二区域，所述第一区域可以延伸贯穿吸收性芯体的高度且包括第一含量的超强吸收性材料，并且第二区域延伸贯穿吸收性芯体的高度且包括第二含量的超强吸收性材料，并且其中，超强吸收性材料的第一含量比超强吸收性材料的第二含量大。在本发明的其他方面，制造吸收性制品的方法可以包括提供流体可渗透顶部片材、提供流体不可渗透底部片材、以及提供或定位非连续吸收性芯体，所述非连续吸收性芯体定位在顶部片材和底部片材之间，其中，吸收性芯体限定高度且包括多个超强吸收性区段，所述多个超强吸收性区段限定在其间的至少一个通道，并且其中，所述多个超强吸收性区段中的至少一个限定第一区域和第二区域，所述第一区域可以延伸贯穿吸收性芯体的高度且包括第一含量的超强吸收性材料，并且第二区域延伸贯穿吸收性芯体的高度且包括第二含量的超强吸收性材料，并且其中，超强吸收性材料的第一含量比超强吸收性材料的第二含量大。本领域技术人员将构思到在本申请的范围和精神内的许多其他可能的变化。例如，在对本申请的变型中，吸收性芯体可以包括超强吸收性颗粒和绒毛纤维的混合物；第一和第二区域可以靠近彼此，其中，第一和第二区域中的一个邻近于所述至少一个通道，并且第一和第二区域中的另一个与所述至少一个通道侧向隔开；第一区域可以在所述至少一个超强吸收性区段的中央部分中布置，并且第二区域可以围绕第一区域的周边定位；第一和第二含量的超强吸收性材料可以穿过第一和第二区域均匀地分布。
