Abstract
本发明提供了用于可穿着吸收制品的可重复使用的外覆盖件。
Description
发明领域
一般来讲,本公开的实施方案涉及可重复使用的吸收制品。具体地讲,本公开的实施方案涉及具有可重复使用的外覆盖件的可穿着吸收制品。
发明背景
可穿着吸收制品包括可重复使用的尿布和可重复使用的失禁内衣。可穿着吸收制品在被穿着者穿着期间可接收和容纳身体排泄物。一些可穿着吸收制品具有可重复使用的外覆盖件。可重复使用的外覆盖件可用各种材料以许多构型来制成。可重复使用的外覆盖件的设计可影响可穿着吸收制品贴合在穿着者身上的方式。遗憾的是,一些可重复使用的外覆盖件在洗涤之后性能变得较差。例如,一些可重复使用的外覆盖件在洗涤时会收缩和/或拉伸。这种尺寸和/或形状上的变化可导致可穿着吸收制品在穿着者身上松垂或下滑,从而导致可穿着吸收制品使人感觉不适、看起来不美观并且由于制品趋于渗漏而性能变得较差。又如,一些可重复使用的外覆盖件在洗涤时经历弹性上的实质变化。这些变化可能需要用更大的力来拉伸腿部开口,从而导致皮肤印记,或可导致力的损失,所述损失可导致在腿部开口处产生间隙。又如,一些可重复使用的外覆盖件经历卸荷力的减小,所述减小可导致较差的持续贴合性和渗漏。
附图概述
图1示出了可在前部扣紧的可穿着吸收制品的内侧的平面图,所述吸收制品具有可重复使用的外覆盖件。
发明详述
本公开的实施方案包括在洗涤之后性能良好的、可重复使用的外覆盖件。这些外覆盖件的设计有助于防止可穿着吸收制品在穿着者身上松垂或下滑。因此,具有本公开的可重复使用的外覆盖件的可穿着吸收制品可使人感觉舒适、看起来美观且性能良好,因为这些制品趋于在穿着者身上保持固定并且不渗漏。
吸收制品包括用于卫生防护的产品、用于卫生用途的产品等。一些吸收制品为可穿着的。可穿着吸收制品被构造成穿着在穿着者身体的下体上或穿着在下体周围。可穿着吸收制品的实例包括尿布、训练裤和失禁内衣。
可穿着吸收制品可包括吸收芯。在整个本公开中,术语吸收芯是指可穿着吸收制品的被构造成吸收身体流出物的部分,所述身体流出物从穿着者的身体被接收到制品中。吸收芯可以各种不同方式构造,如本领域的普通技术人员将会理解的那样。吸收芯可包括一种或多种吸收材料,诸如木浆和/或超吸收颗粒,并且可包括用于接收、容纳、存储和/或处理身体排泄物的一种或多种附加组合物、材料或结构,如本领域已知的那样。此外,吸收芯还可在外表面上和/或在所述组合件内包括下列一种或多种组合物:诸如洗剂、香料和感觉剂。吸收芯可被构造为斗形吸收芯、可移除吸收芯、可置换吸收芯、吸收芯插件等。吸收芯可为吸收芯组合件的一部分,所述组合件包括一个或多个层诸如液体可透过的顶片、采集层、分配层、存储层和液体不可透过的底片。吸收芯组合件还可包括下列各种结构中的一种或多种:诸如阻挡腿箍、粪便容纳隔室、润湿度指示器、用于将芯保持在制品内的扣件、废弃处理带等。在各种实施方案中,吸收芯可直接固定到外覆盖件的内表面上。
在各种实施方案中,吸收芯可如以下美国专利申请序列号中所述的那样构造:12/141,122;12/141,124;12/141,126;12/141,128;12/141,130;12/141,132;12/141,134;12/141,141;12/141,143;和12/141,146。这些专利申请中的每个均以引用方式并入本文。这些专利申请大体上描述了吸收芯构造,所述构造最小化或消除了对与超吸收颗粒组合的透气毡或其他形式的纤维素纤维的需要和包括。
可穿着吸收制品还可包括外覆盖件。在整个本公开中,术语外覆盖件是指可穿着吸收制品的形成制品外表面的一部分(有时候称作底片),所述部分延伸超过吸收芯的边缘,通常覆盖穿着者臀部的显著部分,并且一般被成型成类似于内衣的外观。外覆盖件可按各种方式来构造,如本文所述。在各种实施方案中,外覆盖件可重合于和/或限定可穿着吸收制品的底座。
一些吸收制品为一次性的。一次性吸收制品被构造成在单次使用之后即被废弃处理(例如,不旨在被再使用、复原或洗涤)。一次性吸收制品的实例包括一次性尿布、一次性训练裤、一次性失禁内衣、以及女性护理衬垫和衬里。
一些吸收制品为可重复使用的。如本文所用,术语可重复使用的是指所引用的材料、组件或吸收制品的全部被构造成被复原和/或再使用一次以上的使用循环(例如尿布更换)。在一些可重复使用的吸收制品中,制品的一部分或多部分或基本上全部或全部均可为可洗涤的或耐洗涤的,如本文所限定和描述的那样。例如,可穿着吸收制品可包括可洗涤的或耐洗涤的外覆盖件。在其他可重复使用的吸收制品中,制品的一部分或多部分或基本上全部或全部可能不是可洗涤的或可能不是耐洗涤的。例如,吸收制品可通过使用用于一次性制品诸如尿布中的材料诸如非织造材料而被构造为可重复使用的吸收制品。
在各种实施方案中,可重复使用的外覆盖件可被构造成执行各种功能,所述功能向制品的穿着者和/或穿着者的护理人员提供各种有益效果。在各种实施方案中,可重复使用的外覆盖件可被构造成提供液体不可渗透性,这可帮助吸收制品容纳身体排泄物。在各种实施方案中,可重复使用的外覆盖件可被构造成提供蒸汽渗透性(例如透气性),这可帮助穿着者保持健康的皮肤。在各种实施方案中,可重复使用的外覆盖件可被构造成在一个或多个特定方向上为可弹性延展的、不可弹性延展的和/或不可延展的。在各种实施方案中,可重复使用的外覆盖件的至少一部分诸如内层的一部分可为吸收性的以控制从吸收芯发生轻微渗漏事件。
具体地讲,可重复使用的外覆盖件的一部分或多部分或基本上全部或全部均可被构造成在以下情况下延伸并松弛至特定程度:在制品被穿用到穿着者身上期间、在制品被穿着者穿着期间、以及在制品容纳身体排泄物期间。可重复使用的外覆盖件可被构造成在制品被穿用到穿着者身上期间容易延伸以有利于穿用。可重复使用的外覆盖件还可被构造成在制品被穿着期间充分地延伸以帮助适应于穿着者的运动,同时提供适形的贴合性。可重复使用的外覆盖件还可被构造成以足够的张力适当地松弛(即收缩),以在制品被穿着期间提供持续的贴合性并帮助支撑吸收芯。预期本文所公开的任何可重复使用的外覆盖件均可用于本文所公开的可穿着吸收制品的任何实施方案。
如本文所用,术语‘可洗涤的’是指所引用的材料、组件或吸收制品的全部均被构造成耐受大数目(例如至少10,在一些实施方案中至多50,在其他实施方案中50以上)次数的机洗及烘干循环(由AATCC测试方法124-2001定义,如本文所述),而不会显著地劣化制品的外观或性能而使其变得不适用于其预期的功能性和/或用途。如本文所用,术语“洗涤”或“洗涤循环”是指机洗及烘干循环,如上所述。由于手洗及晾干通常对吸收制品的应力作用要比机洗及烘干小得多,因此预期可机洗且可烘干的材料、组件或制品应当也可手洗且可手工干燥至少同样多的循环次数。例如,可重复使用的可穿着吸收制品可包括可洗涤的外覆盖件。可洗涤的制品被设计成适于在很多次洗涤之后使用,类似于衣服类型。
如本文所用,术语耐洗涤的是指所引用的材料或组件或吸收制品的全部均被构造成耐受小数目(例如至少1次,在一些实施方案中至多5次,在其他实施方案中5次以上)的机洗及烘干循环(如AATCC测试方法124-2001所定义且如本文所述),而不会显著地劣化制品的外观或性能而使其变得不适用于其预期的功能性和/或用途。例如,可重复使用的可穿着吸收制品可包括耐洗涤的外覆盖件。耐洗涤的制品一般在少于可洗涤的制品的洗涤循环次数之后就经历劣化。例如,耐洗涤的材料可在5或10次洗涤循环之后经历外观或性能上的显著劣化。
图1示出了可在前部扣紧的可穿着吸收制品101的内侧(面向穿着者侧)的平面图。尽管本公开涉及可在前部扣紧的可穿着吸收制品,但本公开也设想可穿着吸收制品的可供选择的实施方案,如本文所述,其中可穿着吸收制品为可在后部扣紧的或可在侧部扣紧的。因此,被描述为可在前部扣紧的本公开的可穿着吸收制品的每个实施方案也可被构造成可在后部扣紧的,如本领域的普通技术人员将会理解的那样。
在图1中,纵向中心线113和横向中心线117提供用于指称可穿着吸收制品101的各部分的相对位置的参考线。当第一部分比第二部分更靠近纵向中心线113时,可认为第一部分在第二部分的横向内侧112。类似地,可认为第二部分在第一部分的横向外侧114。当第三部分比第四部分更靠近横向中心线117时,可认为第三部分在第四部分的纵向内侧116。类似地,可认为第四部分在第三部分的纵向外侧118。图1包括指示关于可穿着吸收制品101的横向内侧112、横向外侧114、纵向内侧116和纵向外侧118的相对方向的箭头。在整个本公开中,除非另外指明,对纵向尺寸、测量、线或方向的指称是指基本上或完全平行于纵向中心线113的尺寸、测量、线或方向,并且对横向尺寸、测量、线或方向的指称是指基本上或完全平行于横向中心线117的尺寸、测量、线或方向。
可穿着吸收制品101包括外覆盖件121,所述外覆盖件限定制品101的最外边缘。外覆盖件121包括内层121-A和外层121-B;在图1中,内层121-A被示出为局部破裂开的以示出外层121-B。外覆盖件121还包括前部123和后部125。预期在各种实施方案中,外覆盖件121可被构造为本文所公开的任何可重复使用的外覆盖件,所述外覆盖件包括可洗涤的外覆盖件和/或耐洗涤的外覆盖件。
前部123为当可穿着吸收制品101被穿着者穿着时可穿着吸收制品101的设置成大致邻近穿着者腹部和/或位于穿着者腹部下面的部分。取决于指称的上下文,对“前部”的指称可指前部自身、前部中的元件的一部分或多部分或基本上全部或全部、和/或在前部中的设置。后部125为当可穿着吸收制品101被穿着者穿着时可穿着吸收制品101的设置成大致邻近穿着者背部和/或位于穿着者背部下面的部分。取决于指称的上下文,对“后部”的指称可指称后部自身、后部中的元件的一部分或多部分或基本上全部或全部、和/或在后部中的设置。可穿着吸收制品101的横向中心线117在前部123和后部125之间形成边界。除非另外指明,上述的前部和后部这套术语在整个本公开中是针对可穿着吸收制品而使用的。可穿着吸收制品101也包括从前部123延伸至后部125的吸收芯127。
外覆盖件121还包括后腰边缘106和后弹性腰带107。后弹性腰带107设置成邻近后腰边缘106,并且横跨后部125的一部分横向延伸。外覆盖件121还包括前腰边缘108。在各种实施方案中,外覆盖件可包括前弹性腰带,所述前弹性腰带设置成邻近前腰边缘并且横跨前部的一部分横向延伸。外覆盖件121还包括具有腿箍部分186的纵向侧边,当制品101被穿着时所述腿箍部分至少部分地环绕穿着者的腿部。腿弹性带187设置成邻近腿箍部分186并且纵向延伸至前部123的一部分和后部125的一部分。
外覆盖件121还包括侧部152、侧耳片153和扣件154。侧部152设置在后部125中,在外覆盖件121的最窄部分的横向外侧。虽然侧部152被示出为是在纵向中心线113的右边,但外覆盖件121还包括具有相同构型的另一个侧部,其在纵向中心线113的左边。侧部152包括侧耳片153,所述侧耳片为外覆盖件121的从外覆盖件121的纵向侧边横向向外延伸的部分,如所提供的供参考的虚线所示。在各种实施方案中,侧耳片的一部分或多部分或基本上全部或全部均可由外覆盖件的一部分形成,或可由连结到外覆盖件上的独立元件形成。外覆盖件121包括作为另一侧部的一部分的第二侧耳片。侧耳片153中的每个均包括用于将后部125扣紧到前部123上的扣件154。
外覆盖件121包括总体纵向长度191,所述长度是沿纵向中心线从后腰边缘106测量至前腰边缘108。外覆盖件121还包括后腰区的总体横向宽度193,所述宽度是横跨后部125的最宽部分而测量。外覆盖件121还包括扣件之间的横向宽度195,所述宽度是沿外覆盖件121的后耳片154上的扣件154的边缘在最远横向内侧点之间测量。尺寸191,193和195为按本文所述的测试方法测量的尺寸。类似尺寸可类似地定位在用于裤型可穿着吸收制品的外覆盖件中,如本领域的技术人员将会理解的那样。
示例性可洗涤的外覆盖件
下文描述用于可在前部扣紧的可穿着吸收制品的示例性可洗涤的外覆盖件。所述示例性可洗涤的外覆盖件包括外层、内层、左侧腿围和右侧腿围、前腰带和后腰带、锚定带、着陆区、侧耳片扣件、侧耳片硬化件和吸收芯扣紧元件。
在整个本公开中,术语正面是指材料的将位于成品制品的外侧上的侧面,并且术语反面是指材料的将位于成品制品的内侧上(或在具有多个层的实施方案中,位于成品制品的各层之间)的侧面。当完成时,外层的正面将为面向衣服侧,并且内层的正面将为面向穿着者侧。
所述示例性可洗涤的外覆盖件的每个元件均由一种或多种特定材料形成。外层材料为一种由Modal与Lycra制成的柔软且可拉伸的针织织物。例如,外层材料可为95%Modal和5%Lycra。内层材料由两种材料制成。被构造成设置在制品后部中的内层材料被构造成为可横向拉伸的以提供舒适的贴合性。后部内层材料为一种由聚酯与斯潘德克斯制成的柔软且可拉伸的针织织物。例如,内层材料可为94%聚酯和6%斯潘德克斯。被构造成设置在制品的裆部和前部中的内层材料被构造成为疏水的以阻抗尿液渗透。例如,内层材料可为90%Nylon Tricot和10%斯潘德克斯。
腿围和腰带由弹性的内部材料和作为柔软的可延展织物的外部材料形成。例如,内部弹性带材料可为天然弹性的,为约10mm宽。内部弹性带材料类似于后部内层材料。外部织物带材料类似于外层材料。
锚定带材料为一条由聚酯与斯潘德克斯制成的可拉伸的针织织物。例如,所述可拉伸的针织织物可为90%聚酯和10%斯潘德克斯,为25mm宽。锚定带材料被构造成比外层材料具有更高的弹性模量和更低的弹性滞后。着陆区和侧耳片扣件分别包括具有可缝接的套环补片和吊钩补片的机械钩-环扣紧系统。耳片硬化件材料为织造的可熔界面,以帮助耳片阻抗折叠或屈曲。吸收芯扣紧元件也为被构造成与吸收芯上的吊钩扣紧的套环补片。
为了制造所述示例性可洗涤的外覆盖件,首先将每种材料切割成所期望的形状。将外层材料和内层材料切割成相同的形状,所述形状为外覆盖件的总体形状。
对于腿围,切割出两个内部弹性带材料片;将每个均切割成用于外覆盖件的左纵向侧边或右纵向侧边的可收缩腿箍部分的长度。例如,内部弹性腿围的长度可为约220mm。此外,也切出两个外部织物带材料片;将每个均切割至特定长度和宽度,使得每个外部织物腿围材料片均可在纵向上对半折叠以包封内部弹性腿围材料片。
类似地,对于腰带,切出两个内部弹性带材料片;将每个均切割至用于外覆盖件的前端或后端的可收缩腰部边缘部分的长度。例如,内部弹性腰带的长度可为约245mm。此外,还切出两个外部织物带材料片;将每个均切割至特定长度和宽度,使得每个外部织物腰带材料片均可在纵向上对半折叠以包封内部弹性腰带材料片。
将一个锚定带按定长切割以从一个后侧耳片贴合至另一个后侧耳片。将两个侧耳片扣件切割成贴合在外覆盖件后部上的侧耳片上。将一个着陆区切割成适应于侧耳片扣件并且贴合在外覆盖件前部上。将八个侧耳片硬化件切割成在侧耳片内侧贴合在外覆盖件的前部和后部中的每个侧边上。将两个吸收芯扣件元件切割成适应于吸收芯上的吊钩。
其次,将切割的材料装配在一起。将着陆区缝接到外覆盖件前部的正面上。将侧耳片硬化件中的四个熔合到外层的反面上,每个各自位于前部和后部上的左侧耳片和右侧耳片处。
将腿围缝接到内层的反面和外层的反面上,即缝接在外覆盖件的左纵向侧边和右纵向侧边上的可收缩腿箍部分处。在该缝接期间,在内层和外层基本上松弛时预拉伸所述每个腿围的中部。对于每个腿围,固定内部弹性腿围材料的端部,但中部能自由地在外部织物腿围材料的内侧移动。
类似地,将腰带缝接到内层的反面和外层的反面上,即缝接在外覆盖件的前端和后端上的可收缩腰部边缘部分处。在该缝接期间,在内层和外层基本上松弛时预拉伸所述每个腿围的中部。对于每个腰带,固定内部弹性腰带材料的端部,但中部能自由地在外部织物腰带材料的内侧移动。
将锚定带在后部侧耳片和前部侧耳片处缝接到内层的反面上。在该缝接期间,锚定带和内层均为基本上松弛的;即,当将它们在一起平坦展开时,这两个元件均不是相对于彼此为预拉伸的。锚定带的中部不缝接到内层上。将侧耳片扣件在左后侧耳片和右后侧耳片处缝接到内层的正面上。将吸收芯扣紧元件缝接到内层的前部和后部的正面上。将侧耳片硬化件中的四个熔合到内层的反面上,每个各自位于前部和后部上的左侧耳片和右侧耳片处。然后将内层和外层缝接在一起并且反转以便使正面翻出。所述示例性可洗涤的外覆盖件就完成了。在完成的外覆盖件中,锚定带的中部能自由地相对于内层和外层移动。此外,在完成的外覆盖件中,锚定带不是相对于内层或外层预拉伸的。
该示例性可洗涤的外覆盖件旨在作为一个非限制性实例,并且可按如下所述的众多方式变化。外覆盖件的任一元件均可包括一个或多个子组件;即,元件可由一个以上的材料片或一种以上的材料类型形成。外覆盖件的任一层或两层均可包括单一材料层或可包括两个或更多个层和/或两种或更多种材料。内层在横向和纵向上均可为可拉伸的。可处理内层以使其变得更具疏水性。内层可横跨其区域具有变化的拉伸性、疏水性和/或透气性。
外覆盖件也可横跨其区域具有变化的拉伸性、疏水性和/或透气性。外覆盖件可不具有锚定带或可具有任何数目的锚定带或其他锚定系统组件。例如,可洗涤的外覆盖件可被构造成包括以下专利申请中所述的锚定系统中的一个或多个元件:以代理人档案号11225M提交于2010年1月14日的题目为“Reusable Wearable Absorbent Articles with Anchoring Systems”的美国非临时性专利申请,该专利申请以引用方式并入本文。作为一个附加实例,可洗涤的外覆盖件可被构造成包括以下专利申请中所述的锚定系统中的一个或多个元件:以代理人档案号11565提交于2010年1月14日的题目为“ReusableWearable Absorbent Articles with Anchoring Subsystems”的美国非临时性专利申请,该专利申请以引用方式并入本文。
外覆盖件可包括在洗涤期间用以保护扣紧元件的结构(例如用以覆盖吊钩或覆盖邻近吊钩的可暂时固定扣件的区域的保护片)。吸收芯可通过可添加到外覆盖件和/或吸收芯上的任何种类的机构来连接到外覆盖件上,所述机构诸如口袋、箍、带、套环、钩-环型扣件或任何类型的扣件。外覆盖件可包括如本领域已知的宏观扣件或任何其他扣紧系统。腿围和腰带构造可为单一材料、层压体等。腿围和腰带可仅固定到内层上或仅固定到外层上。
在各种可供选择的实施方案中,所述示例性可洗涤的外覆盖件可按众多其他方式变化,具有附加和/或可供选择的材料、结构、构型和装配方法,如本领域的技术人员将会理解的那样。
可洗涤的外覆盖件材料可包括尿布、裤、内衣、表演服、运动服或一般衣服或纺织物领域中已知的任何天然材料或合成材料。这些材料可包括天然材料诸如棉、羊毛、竹、大麻、丝绸、人造丝等、以及这些材料与合成纤维的共混物。适用于可洗涤的外覆盖件的示例性合成材料可包括聚酯、尼龙、Lycra、斯潘德克斯或其他弹性体、可透气的防水材料诸如GORE(W.L.Gore&Associates,Inc.(Elkton,MD))、包括微囊包封的相变聚合物材料的织物诸如Outlast ComforTemp织物(Outlast Technologies(Boulder,CO)-见例如US 6,514,362和US 6,207,738)、(INVISTA(Wichita,KS))等。这些材料优选地包括至少一种纤维基材料,诸如织物或织造或非织造纤维网。然而,外覆盖件可附加地包括薄膜层,以为外覆盖件提供增强的液体渗透抗性和/或弹性性能。可通过向外覆盖件上添加其他材料来增加或增强弹性性能,所述其他材料包括弹性股线、带、稀松布等。可洗涤的材料可被成形为任何已知的编织物或织物形式,包括鸟眼织物、毛圈织物、抓绒、法兰绒、针织、拉伸针织物、颗粒绒、仿麂皮织物、微抓绒、缎、丝绒、Burley针织物、和(Polartec,LLC(Lawrence,MA))。针织纺织物(它们可比织造或非织造材料更具固有的可拉伸性和弹性)可赋予外覆盖件更好的贴合性、舒适性和/或外观。掺入斯潘德克斯纤维或其他弹性体也可增强拉伸性和弹性,从而与不包括此类弹性体纤维的纺织物相比,赋予外覆盖件更好的贴合性、舒适性和/或外观。
可洗涤的外覆盖件材料的具体适宜实例包括下列的共混物的平针针织物:人造丝(93%)和斯潘德克斯(7%)纤维;Modal(94%)和斯潘德克斯(6%)纤维;棉和斯潘德克斯纤维;以及竹和斯潘德克斯纤维。具有等于或大于约30%、或50%、或100%、或150%、或甚至200%的拉伸能力的材料可为所期望的。合适的材料实例可具有约0.09-0.15克/平方英寸/层的基重,或其他基重。
可洗涤的外覆盖件材料可被选择成赋予可穿着吸收制品所期望的舒适性、外观和性能。在一些情况下,可期望选择足够廉价的可洗涤的外覆盖件材料以允许废弃处理(如果受到大范围脏污或损坏),同时最小化成本或良知问题。
预期本文所公开的任何可洗涤的外覆盖件均可用于本文所公开的可穿着吸收制品的任何实施方案。所述示例性可洗涤的外覆盖件还可适用于裤型可穿着吸收制品。
示例性耐洗涤的外覆盖件
下文描述用于可在前部扣紧的可穿着吸收制品的示例性耐洗涤的外覆盖件。所述示例性可洗涤的外覆盖件包括三层的层压体,其包括两层可延展非织造材料和夹置在非织造材料之间的可弹性拉伸的薄膜。第一可延展非织造材料形成外覆盖件的面向衣服侧,而第二可延展非织造材料形成外覆盖件的面向穿着者侧。第一可延展的非织造材料为27gsm的HEC非织造材料,诸如得自Fiberweb/BBA的Excell Style 382D。可弹性拉伸的薄膜包括27gsm的Vistamaxx薄膜(其树脂得自Exxon-Mobil)与约5gsm的聚乙烯表皮层。第二可延展的非织造材料为22gsm的非织造材料,诸如得自Fiberweb France的Sofspan 200。
将所述薄膜和第二非织造材料挤出粘结在一起以形成双层的层压体。所述双层的层压体作为材料M18-2038C得自Clopay Corp.。将第一非织造材料通过得自Bostik的0.0006g/in2的2031螺旋粘合剂而粘结到双层的层压体的薄膜侧上,以形成三层的层压体。外覆盖件还包括设置在三层的层压体内的锚定带。锚定带为约25mm宽的弹性体薄膜条,其设置在外覆盖件的后腰区中,取向成平行于外覆盖件的横向中心线并且从外覆盖件的一个侧边上的扣件延伸至外覆盖件的另一侧边上的扣件。然后使用环轧过程将三层层压材料的外覆盖件机械活化(即,在横向上递增拉伸)。在环轧过程中,环轧齿距为0.100″,并且啮合深度为0.158″。
例如,耐洗涤的覆盖件可被构造成包括以下专利申请中所述的锚定系统中的一个或多个元件:以代理人档案号11225M提交于2010年1月14日的题目为“Reusable Wearable Absorbent Articles with Anchoring Systems”的美国非临时性专利申请,该专利申请以引用方式并入本文。作为一个附加实例,耐洗涤的覆盖件可被构造成包括以下专利申请中所述的锚定系统中的一个或多个元件:以代理人档案号11565提交于2010年1月14日的题目为“Reusable Wearable Absorbent Articles with Anchoring Subsystems”的美国非临时性专利申请,该专利申请以引用方式并入本文。
该示例性耐洗涤的外覆盖件旨在作为一个非限制性实例。在可供选择的实施方案中,所述示例性耐洗涤的外覆盖件可按众多方式变化,具有附加和/或可供选择的材料、结构、构型和装配方法,如本领域的技术人员将会理解的那样。
耐洗涤的外覆盖件可仍然为足够廉价的以允许废弃处理它们而不产生成本或良知问题(如果受到大范围脏污或损坏)。耐洗涤的外覆盖件材料可包括任何本文所述的材料,包括所设想的用于可洗涤的或一次性外覆盖件的一种或多种材料。如果选择用于可洗涤的外覆盖件的材料,则可利用通常不太昂贵的、较低品质的(例如,较低的基重、稍次的纤维品质)型式以形成耐洗涤的外覆盖件。如果选择用于一次性制品(例如一次性尿布)的材料,则较高基重和/或品质的材料可为适当的。也设想将此类材料的共混物或层压体用于耐洗涤的外覆盖件。
例如,可改进一次性可穿着吸收制品的设计以制造耐洗涤的制品。例如,可通过移除吸收芯以及改进和/或置换制品的剩余组件中的一个或多个来改进如以下专利申请所述进行构造的可穿着吸收制品以使所述制品变得更结实并因此耐洗涤:提交于2008年12月18日的题目为“Disposable AbsorbentArticle with Substantially Continuous Distributed Absorbent Particulate PolymerMaterial and Method”的美国专利申请公布号20080312617,该专利申请以引用方式并入本文。
作为另外一种选择或以组合方式,可通过如下方法来组合耐洗涤的外覆盖件的所述各种组件材料:使用劳动密集度较低的、但不太耐用的方法诸如粘合剂或机械粘结或热粘结(例如,与缝接相对)。进一步,材料的构造可影响材料的强度和其在经受洗涤循环时耐受劣化的能力。例如,材料的类型、强度和粘结度可影响材料的强度,进而可影响材料是否为可洗涤的或耐洗涤的。
就耐洗涤的外覆盖件而言,材料可包括尿布或裤领域中已知的任何天然或合成非织造纤维网和/或薄膜材料。可用来构造外覆盖件的耐洗涤的材料可包括如下纤维的非织造纤维网材料:聚丙烯和/或聚乙烯纤维、聚酯纤维、和用来形成用作一次性尿布组件的非织造纤维网材料的任何其他合成纤维、以及它们的共混物。天然纤维诸如棉、亚麻布、羊毛、竹、大麻、丝绸、人造丝等可与合成纤维共混以形成这种适用作外覆盖件的组件层的非织造纤维网。除了这些材料以外,还可在耐洗涤的外覆盖件中使用薄膜,诸如聚烯烃薄膜(微孔的或非微孔的)。
可被认为适用作耐洗涤的外覆盖件材料的纤维、非织造材料以及非织造材料和薄膜的层压体的非限制性实例可见于美国专利7,223,818;7,211,531;7,060,149;6,964,720;6,905,987;6,890,872;6,884,494;6,878,647;和5,518,801;以及美国公布的专利申请2008/0319407;2008/0045917;2007/0293111;2007/0287983;2007/0287348;2007/0249254;2007/0203301;和2005/0164587。
还可将耐洗涤的外覆盖件材料选择成赋予外覆盖件期望的舒适性、外观和性能。在一些情况下,也可期望选择足够廉价的耐洗涤的外覆盖件材料以允许废弃处理(如果受到大范围脏污或损坏),同时最小化成本或良知问题。
外覆盖件还可或附加地可包括层压的或大体上独立的薄膜层(其可为弹性的),以增强液体渗透抗性和/或弹性性能。也可通过以层、带或条形式向外覆盖件上添加其他材料来增加或增强弹性性能,所述材料包括弹性股线、带、稀松布、泡沫等。薄膜层可与可洗涤的材料或耐洗涤的材料层压在一起。薄膜层可包括基于以下材料的弹性体:KRATON(Kraton Polymers U.S.,LLC(Houston,Texas)的产品);VISTAMAXX,得自ExxonMobil ChemicalCompany(Houston,TX);FLEXAIRE、EXTRAFLEX或FABRIFLEX(TredegarFilm Products Corporation(Richmond,VA)的产品)、以及得自FulflexElastomerics Worldwide(Greenville,TN)的各种不含胶乳的弹性体片材。
作为布料或非织造层的纤维质组件或作为薄膜层的弹性体材料的利用改善了拉伸性和弹性(这可被认为有益于对穿着者的身体结构和运动的适应,诸如对穿着者的臀部和/或腰部区域周围情况的适应),并且改善了贴合性和舒适性。因此,如果可包括薄膜层,则其可赋予外覆盖件附加的液体容纳能力。薄膜层可包括基本上液体不可透过但蒸汽可透过的薄膜,以便在其被穿着期间提供透气性并且减小外覆盖件内的湿度,从而在期望有液体容纳能力的部位减小皮肤水分过多的可能性。
外覆盖件的各层或元件可通过尿布或衣服领域中已知的任何方法彼此接合,包括例如粘合剂、机械粘结、超声波粘结、缝接、缝合、包边、卷边等。
预期本文所公开的任何耐洗涤的外覆盖件均可用于本文所公开的可穿着吸收制品的任何实施方案。也可添加所述示例性耐洗涤的外覆盖件,以用于裤型可穿着吸收制品。
如果可重复使用的外覆盖件被身体流出物诸如尿液、粪便或汗液或环境污染物所脏污,则它们在重复使用之前需要洗涤。护理人员也可选择洗涤外覆盖件以使其复新、去除恶臭、添加悦人的芳香剂、或大致复原其形状、整洁度和/或外观。一般来讲,护理人员可期望更昂贵的外覆盖件可洗涤更大数目的洗涤循环次数,而不显著地劣化外覆盖件的物理特性或外观。与可洗涤的外覆盖件相比,耐洗涤的外覆盖件一般可由不太昂贵的材料制成;因此,与可洗涤的外覆盖件相比,预期随着洗涤循环次数的不断增加它们会更快速地劣化,例如,在较少次数的洗涤循环之后劣化超过有效点。
尽管外覆盖件在多次洗涤循环之后的审美外观对于一些护理人员所感知到的外覆盖件的价值来讲是重要的,但可接受的外观在很大程度上取决于个体偏好。此外,甚至具有更“穿旧”外观的外覆盖件在某些场所中(例如,在家里)或在某些使用场合中(例如,在夜间或当孩子生病诸如得了痢疾时)也是可接受而被穿着的。因此,更为关键的是,耐洗涤的外覆盖件和可洗涤的外覆盖件分别在至少一次洗涤循环和10次洗涤循环之后能够具有它们的预期用途。
外覆盖件应当在预期的最少次数的洗涤循环之后保持显著的尺寸稳定性。由于外覆盖件的尺寸显著地影响外覆盖件所将舒适地、牢固地和/或无间隙地贴合的穿着者的身材,因此希望在外覆盖件的使用寿命内,外覆盖件的尺寸变化小于约10%,更优选地小于约5%。一些可洗涤的外覆盖件可从第一次洗涤循环(即,对先前未洗涤过的外覆盖件进行初始洗涤)经历显著的一次性收缩,收缩方式类似于其他耐用可穿着制品诸如由纺织物和/或织造材料制成的衣服固有地经历收缩的方式。在这些情况下,制品或其组件可由制造商或消费者进行预洗涤,以避免在制品的第一次使用循环中产生任何潜在的贴合性问题。然而,对于确实从第一次洗涤循环经历了显著的一次性收缩的可洗涤的外覆盖件来讲,希望在第一次洗涤之后外覆盖件的尺寸变化小于约10%,更优选地小于约5%。作为另外一种选择,可洗涤的制品可由耐收缩材料制成。另一方面,就耐洗涤的制品而言,由于此类制品的预期产品使用寿命较短,因此希望它们在一次洗涤循环之后保持尺寸稳定性。
在洗涤之后,外覆盖件应当还保持其拉伸能力,尤其是在腰区中的拉伸能力,以便能够适应于范围更广泛的穿着者的身材和/或运动。给定的期望延伸量(即,用于尺寸调整或舒适的运动自由度)应当以外加应力来获得,所述应力在由穿着者施加到制品上的典型力的范围内。尽管进行了洗涤,但获得期望的延伸所需的力例如全产品后部延伸力在制品的使用寿命期间应当保持相对恒定,以便保持相同的贴合性范围和容纳性能。如果给定延伸下的全产品后部延伸力随着重复的洗涤循环而显著地增大,则产品尺寸范围可减小,因而产品可变得太紧,从而导致皮肤印记。如果全产品后部延伸力随着重复的洗涤循环而显著地减小,则产品可能会贴合得太松散,从而导致松垂、间隙和增加的身体流出物渗漏。在制品的预期使用寿命期间,给定延伸下的全产品后部延伸力在重复的洗涤循环之后的变化应当不超过约25%,且更优选地10%。如同尺寸稳定性的情况一样,可洗涤的外覆盖件在第一次洗涤循环之后可经历大于该值的特性上的变化,但之后保持此类相对稳定的全产品后部延伸力。
另外,在洗涤之后,外覆盖件应当在制品被拉伸且能够恢复之后在腰区中保持张力。如果给定延伸下的全产品后部延伸卸荷力减小得太多,则产品可具有显著松垂、间隙和由于持续贴合性不足而渗漏的风险。在制品的预期使用寿命期间,给定延伸下的全产品后部延伸卸荷力在重复的洗涤循环之后的减小应当不超过约25%,且更优选地10%。在制品的预期使用寿命期间,25%延伸下的绝对全产品后部延伸卸荷力在重复的洗涤循环之后应当保持大于约0.5N,优选大于约0.75N和1.0N。
此外,尽管经受了洗涤循环,但外覆盖件的腿围中的弹性力在制品的使用寿命期间应当也保持相对恒定,以便保持相同的贴合性范围和容纳性能。如果当外覆盖件经受洗涤循环时,腿围中的弹性力显著地增加,则产品尺寸范围可减小,因而产品可变得太紧,从而导致皮肤印记。如果当外覆盖件经受洗涤循环时,腿围中的弹性力显著地减小,则产品可能会贴合得太松散,从而导致松垂、间隙和增加的身体流出物渗漏。在制品的预期使用寿命期间,给定延伸下的腿围中的弹性力的变化在重复的洗涤循环之后应当不超过约25%,且更优选地10%。如同尺寸稳定性的情况一样,可洗涤的外覆盖件在第一次洗涤循环之后可经历大于该值的特性上的变化,但之后在腿围中保持此类相对稳定的弹性力。
在洗涤之前和在一次或多次洗涤循环之后,各自评测了上述的示例性可洗涤的外覆盖件的三个样本和示例性耐洗涤的外覆盖件的三个样本。在各种次数的洗涤循环之后,在这些处在平坦展开取向的外覆盖件上测量了若干个重要尺寸,包括:(1)外覆盖件的总体纵向长度,其是沿纵向中心线从外覆盖件的一端测量至另一端;(2)外覆盖件的后腰区的总体横向宽度,其是在耳片上的横向最外侧点之间横跨后腰区的最宽部分而测量;和(3)沿外覆盖件后耳片上的扣紧元件的边缘在最远横向内侧点之间的横向宽度。所有这些尺寸均是根据本文所述的测量准则而测量的。另外,根据本文所述的测试方法,外覆盖件的弹性腿围中的弹性力是在85%的延伸下测量的。最后,根据本文所述的测试方法,在25%应变(第一次延伸循环)下,横跨外覆盖件的后部,从一个扣紧元件上的第一点至定位成与第一点横向相对且处在另一个扣紧元件上的第二点测量了全产品后部延伸力。源自该测试的数据提供于下表中作为所述三个样本的平均值。
表1
如表1所示,所述示例性耐洗涤的外覆盖件的尺寸在一次洗涤循环之后保持相对不变,并且仍然有效,但在5次或10次洗涤循环之后减小了约10%。另一方面,所述示例性可洗涤的外覆盖件的尺寸在一次洗涤循环之后经历了5至7%的一次性收缩,但随后在至少10次洗涤循环中保持相对恒定。
如表1所示,所述示例性耐洗涤的外覆盖件的在85%应变下的腿部力在5次洗涤循环之后增加了60-70%。所述示例性可洗涤的外覆盖件的在85%应变下的腿部力在第一10次洗涤循环中保持相对恒定。
如表1所示,所述示例性耐洗涤的外覆盖件的在25%应变(第1载荷和第一卸荷)下的全产品后部延伸力在5次洗涤循环之后经历了显著劣化。所述示例性可洗涤的外覆盖件的在25%应变(第1载荷和第一卸荷)下的全产品后部延伸力在第一次洗涤初始收缩之后保持相对恒定。所述示例性耐洗涤的外覆盖件的全产品后部延伸卸荷力在5至10次洗涤循环之后减小了50%或更多,达到显著地低于1.0N的水平,而所述示例性可洗涤的外覆盖件的全产品后部延伸卸荷力在第一次洗涤初始收缩之后保持相对恒定并且高于1.0N。
在洗涤循环中,吸收制品的组件诸如外覆盖件是根据源自AATCC(美国纺织品染化师协会)测试方法124-2001的规程进行机洗和烘干,其中所选择的参数和变型在下文中列出。
