Description

包括耐用亲水性芯部包裹物的一次性吸收制品
发明领域
本发明涉及包括耐用亲水性芯部包裹物的一次性吸收制品以及生产上述制品的方法。
发明背景
诸如尿布和成人失禁用品之类的一次性吸收制品已为本领域所熟知。这样的一次性制品收集和保留穿着者沉积在其上的尿液和粪便。
由合成纤维和/或天然纤维制成的无纺织物一般用于吸收制品,例如作为顶片材料或作为芯部包裹物来包封吸收芯的存储层。这样的无纺织物通常是疏水的。然而,对于卫生制品中的许多应用,需要使用亲水性无纺材料。因此,必须对无纺织物进行相应的处理。
一次性吸收制品的一个典型组分是芯部包裹物。芯部包裹物典型地为设计用来包含储藏层并在储藏层润湿或干燥时提供结构完整性的无纺材料。它们可以为薄纸包裹物,或更典型地它们为被赋予亲水性的无纺材料。
使无纺织物亲水的常用方法是用亲水表面活性剂涂敷无纺材料的表面。由于这种涂敷不会在无纺材料和表面活性剂之间产生牢固的化学键,因此在使用期间吸收制品被润湿后,表面活性剂可能会被冲洗掉。当无纺材料涂敷有表面活性剂时,减少液体透湿时间是所期望获得的效果。液体透湿是指液体通过无纺织物,其中液体透湿时间是指一定量的液体透过无纺材料所花费的时间。然而,由于当涂敷过的无纺织物暴露于液体时表面活性剂被冲洗掉,因此下一次涌流的透湿时间增加。这导致包括这种无纺织物的尿布或其它制品使用期间的性能下降。此外,由于使用了表面活性剂,在液体透湿时间减少的同时,与无纺织物接触的液体的表面张力减小。这种减小是不可取的,因为它会使尿布中尿液的渗漏增加。
使无纺织物亲水的另一种常用方法是采用电晕处理和/或等离子处理。等离子是电离态的气体,可以通过电离气体或液体介质获得。等离子被广泛用于有机材料和无机材料的处理,来促进多种材料间的粘合。具有低表面能的化学惰性表面的聚合物不能够用结合剂和粘合剂良好地涂敷。因此,将这些表面进行处理,以使它们能够与其它基质、涂层、粘合剂和印刷油墨结合。
然而,电晕处理和等离子处理导致处理过的材料在存储后涂层耐久性低,即亲水性随时间下降。
因此,需要一种无纺材料的亲水涂层,该涂层在存储时耐久、润湿时不易被冲洗掉,并且使无纺材料在多次暴露于液体时达到液体快速透湿。

发明详述
本文所用术语“涂层”包括完全覆盖表面或部分表面的涂层(例如,连续涂层,包括在表面上形成薄膜的那些),也包括只可以部分覆盖表面的涂层,诸如干燥后在表面上的覆盖区内留下缝隙的那些涂层(例如,不连续涂层)。后一种类的涂层可包括,但不限于,表面上覆盖和未覆盖的部分及分布的纳米颗粒的网状物,该表面在纳米颗粒间可具有空隙。在一些实施方案中,涂层优选在被涂敷的表面上至少形成一层纳米颗粒,并且是充分均匀的。然而,当本发明所描述的涂层被描述为应用到表面时,应当理解这些涂层不必应用到或覆盖整个表面。例如,即使应用涂层只是对部分表面进行改性,该涂层也会被视为应用到表面。
术语“亲水的”形容纤维或纤维表面可以被沉积在这些纤维上的含水流体(例如含水体液)所润湿。亲水性和润湿性典型地根据流体的接触角和透湿时间(例如穿过无纺织物)所限定。在Robert F.Gould编著的题为“Contactangle,wettability and adhesion”(版权1964)的American Chemical Society的出版物中对此进行了详细的讨论。当流体与纤维(或其表面)间的接触角小于90°,或是流体趋于沿纤维表面自发铺开时(这两种条件通常共存),可以说纤维或纤维表面会被流体润湿(即亲水的)。相反,如果接触角大于90℃并且流体不能沿纤维表面自发铺开,则纤维或纤维表面被认为是疏水的。
本文所用术语“亲水性增强”是指当被涂敷在芯部包裹物基质以制造耐用、亲水性、流体可透过的芯部包裹物时,组合物能够产生耐用、亲水性、流体可透过的芯部包裹物。当依照“测试方法”部分的“透湿测试”和本文进一步所述进行测试时,该包裹物对于第一涌流的液体透湿时间少于或等于约6秒,更优选少于或等于约4秒,并且对于测试液体第五涌流的液体透湿时间优选少于或等于约6秒,更优选少于或等于约4秒。
本文所用术语“包括”是指多种组分、成分或步骤可结合应用于实施本发明。因此,术语“包括”为可扩充的并且包括限制性更强的术语“基本上由...组成”和“由...组成”。
本发明的一次性吸收制品包括吸收芯,至少部分该吸收芯被耐用、亲水性、流体可透过的芯部包裹物所围绕。示例性一次性吸收制品的实施例包括,但不限于,尿布、成人失禁制品、训练短裤、女性卫生垫、紧身短裤衬里等。耐用、亲水性、流体可透过的芯部包裹物包括芯部包裹物基质,该基质被亲水性增强组合物所涂敷。该基质和亲水性增强组合物都将在本文更详细地示例说明。
图1为一次性吸收制品(具体地讲,为尿布20)的平面图,该尿布是依照本发明吸收制品的优选实施方案。尿布以其平展未收缩状态(即,没有弹性引起的收缩)显示。部分结构被切掉以显示尿布20的底层结构,尤其是吸收芯10。尿布20的接触穿着者的部分面向观察者。图1中尿布20的底座22包括尿布20的主体。底座22包括外覆盖件,该外覆盖件包括液体可透过的顶片24和/或液体不可透过的底片26。底座还可以包括包封在顶片24和底片26之间的吸收芯10的大部分或全部。
对于一体的吸收制品,底座22包括添加其它部件以形成复合尿布结构的尿布的主结构。虽然顶片24、底片26和吸收芯10可以多种熟知的构型组装,优选的尿布构型通常描述于1996年10月29日授予Buell等人的题为“Disposable Pull-On Pant”的美国专利5,569,234,以及1999年12月21日授予Robles等人的题为“Absorbent Article With Multi-DirectionalExtensible Side Panels”的美国专利6,004,306。
图1中的顶片24可以是完全或部分弹性化的,或者可以缩短以在顶片24和吸收芯10之间提供空隙空间。包括弹性化的或缩短的顶片的示例性结构更详细地描述于下列文献:1991年8月6日授予Allen等人的题为“Disposable Absorbent Article Having Elastically Extensible Topsheet”的美国专利5,037,416,以及1993年12月14日授予Freeland等人的题为“Trisection Topsheets for Disposable Absorbent Articles and DisposableAbsorbent Articles Having Such Trisection Topsheets”的美国专利5,269,775。

图1中的吸收芯10通常设置在顶片24和底片26之间。吸收芯10包括本文更加详述的耐用、亲水性、流体可透过的芯部包裹物42(本文也称为耐用亲水性芯部包裹物或芯部包裹物)和如图2所示的存储层60。存储层60可以包括通常可压缩的、适形的、对穿着者的皮肤无刺激性,并且能够吸收和保留液体诸如尿液和其它某些身体排泄物的任何吸收材料。存储层60可包括各种各样的通常用于一次性尿布和其它吸收制品的液体吸收材料,诸如粉碎的木浆,这种木浆一般被称为透气毡或软毛。其它合适的吸收材料的实施例包括绉纱纤维素填料、熔喷聚合物(包括共成型的);化学硬化的、改性的或交联的纤维素纤维;薄纸(包括薄纸包裹物和薄纸层压材料)、吸收泡沫、吸收海绵、超吸收聚合物(诸如超吸收纤维)、吸收胶凝材料、或任何其它已知的吸收材料,或材料的混合物。合适的吸收材料的某些组合的实施例为:含有吸收剂胶凝材料和/或超吸收聚合物,以及吸收剂胶凝材料和超吸收纤维等等的软毛。在一个任选的实施方案中,存储层为无透气毡的,即,它不包含透气毡。存储层还可包括少量(典型地少于10%)的非液体吸收材料,诸如粘合剂、蜡、油,等等。
用作吸收组件的示例性吸收结构描述于1989年5月30日授予Alemany等人的题为“High Density Absorbent Members Having LowerDensity and Lower Basis Weight Acquisition Zones”的美国专利4,834,735和1997年7月22日授予DesMarais等人的题为“Absorbent Foam Materials ForAqueous Fluids Made From High Internal Phase Emulsions Having Very HighWater-To-Oil Ratios”的美国专利5,625,222。
图2为沿2-2的剖面图,显示图1的尿布的吸收芯10的一个可供选择的实施方案的部分。在图2中,存储层60被芯部包裹物42以C-折叠方式包裹。芯部包裹物42包括基质,该基质被包含纳米颗粒75的亲水性增强组合物所涂敷。基质可以为无纺材料、聚合物薄膜或它们的组合。基质、亲水性增强组合物、无纺材料和多孔聚合物薄膜均在本文更加详细地示例说明。
本发明的耐用亲水性芯部包裹物提供了具有延长储藏期限和穿着寿命的基质。之前的高能处理往往具有较短的储藏期限。即,在消费者购买后至最终使用和丢弃的这段时间,基质会趋向于失去它的亲水性。在另一方面,表面活性剂处理(诸如现有技术的那些)经常使基质具有足够的储藏期限,但并不具有足够的穿着期限。即,在与身体流体诸如尿液接触后,基质会立即开始失去它的亲水属性。这甚至可能导致表面排斥身体流体,即使吸收制品还没有达到它的全部吸收容量,而该表面是被设计来吸收身体流体的。
当用本发明的亲水性增强组合物处理基质后,本发明的亲水的芯部包裹物不再受到这些限制,它将具有长期的储藏期限和长期的穿着寿命,即芯部包裹物的亲水属性不会随时间或在与身体流体比如尿液接触后充分失去。
在本发明的一个任选的实施方案中,当按照“测试方法”部分的“表面张力的测定试验”和本文的进一步描述进行测试时,亲水性芯部包裹物具有的冲掉表面张力大于约65mN/m。
在本发明的一个任选实施方案中,吸收芯除了包括存储层和耐用亲水性芯部包裹物之外,还包括采集体系,该体系包括上部采集层(面向穿着者)和下部采集层。在一个优选的实施方案中,上部采集层包括无纺织物,而下部采集层优选地包括化学硬化的、加捻的和卷曲的纤维,高表面积纤维和热塑性粘合纤维的混合物。在另一个优选的实施方案中,两个采集层均由优选为亲水的无纺材料来提供。采集层优选与存储层直接接触。此外,存储层或它的部分,诸如上部采集层,可任选地被亲水性增强组合物所涂敷。
图3为沿2-2的剖面图,显示图1的尿布的吸收芯10的一个可供选择的实施方案的部分。在图3中,存储层60被芯部包裹物42所围绕或包裹。芯部包裹物42包括基质,该基质被亲水性增强组合物所涂敷,两者均在本文更加详细地示例说明。
图4为沿2-2的剖面图,显示图1的尿布的吸收芯10的一个可供选择的实施方案的部分。在图3中,存储层60被芯部包裹物42所围绕或包裹。芯部包裹物42包括流体接收顶层70和底层80。流体接收顶层70和底层80可以相同或不同。即,它们可以为被相同的亲水性增强组合物所涂敷的相同基质、被相同的亲水性增强组合物所涂敷的不同基质、或被不同的亲水性增强组合物所涂敷的不同基质,等等。
在本发明的一个任选实施方案中,顶层70和底层80可以包括无纺材料。一种优选的材料为包括纺粘层、熔喷层和另一纺粘层的所谓的SMS材料。顶层70和底层80可由两个或多个分开的无纺材料片来提供,或者它们可以可供选择地由一体的材料片来提供。SMS材料在本文更加详细地示例说明。
在本发明的一个可供选择的实施方案中,只有部分基质被亲水性增强组合物所涂敷。该任选实施方案图示说明于图5和图6。图5为沿2-2的剖面图,显示图1的尿布的吸收芯10的部分。在图5中,存储层60被芯部包裹物42以C-折叠方式包裹。芯部包裹物42包括两部分:被亲水性增强组合物所涂敷的部分,或涂敷部分90,以及未被亲水性增强组合物所涂敷的部分,或未涂敷部分30。
对于图5中所图示说明的可供选择的实施方案存在于图6。图6为沿2-2的剖面图,显示图1的尿布的吸收芯10的一个可供选择的实施方案的部分。在图6中,存储层60被芯部包裹物42所围绕或包裹。芯部包裹物42包括被亲水性增强组合物所涂敷的顶层70,形成涂敷部分90;以及未被亲水性增强组合物所涂敷的底层80,形成未涂敷部分30。
在另一个可供选择的实施方案中,未涂敷部分30可以任选被不同的组合物所涂敷,以赋予它与涂敷部分90不同的物理属性。例如,未涂敷部分30可以被组合物所涂敷,以使得它更加亲水,或它被异于用来涂敷涂敷部分90的亲水性增强组合物所涂敷。
本发明的耐用亲水性芯部包裹物将优选具有的定量在约1克/每平方米(或gsm)和约100gsm之间,更优选在约2gsm和约50gsm之间,甚至更优选在约5gsm和约30gsm之间。
芯部包裹物基质-本发明的耐用亲水性芯部包裹物包括芯部包裹物其质(基质),该基质被亲水性增强组合物所涂敷。本文所关心的基质可包括任何已知类型的基质,包括但不限于,织物、衣服、纺织品和薄膜。在某些实施方案中,基质可包括一种或多种纤维。纤维被定义为动物的、植物的、矿物的或合成来源的纤细的结构。市售纤维具有的直径在小于约0.001mm(约0.00004in)至大于约0.2mm(约0.008in)的范围内变化,并且它们表现为几种不同的形式:短纤维(称为化学短纤维或短切纤维)、连续单纤维(长丝或单丝)、未加捻的连续长丝束(丝束)和加捻的连续长丝束(纱)。
基质可包括由自然产生的纤维(天然纤维)、由人制成的纤维(合成的或人造的纤维)或它们的组合。天然纤维的实施例包括但不限于:诸如羊毛、蚕丝、皮毛和毛发之类的动物纤维;诸如纤维素、棉花、亚麻、亚麻布和大麻之类的植物纤维;以及某些天然存在的矿物纤维。合成纤维可衍生自天然纤维或非天然纤维。例如,衍生自天然纤维的合成纤维的实施例包括,但不限于,人造丝和溶剂法纤维素短纤维,这两种纤维均衍生自纤维素。非衍生自天然纤维的合成纤维可衍生自其它天然来源或衍生自矿物来源。衍生自天然来源的示例性合成纤维包括但不限于诸如淀粉之类的多糖。衍生自矿物来源的示例性纤维包括,但不限于,衍生自石油的诸如聚丙烯、聚乙烯纤维之类的聚烯烃纤维,以及诸如玻璃和石棉之类的硅酸盐纤维。当可能时,合成纤维通常由流体处理方法(例如挤出、拉出或旋转诸如树脂或溶液的流体)形成。合成纤维也可以通过固体处理尺寸减小方法(例如,机械切割较大物体诸如整料、薄膜或织物)形成。
可包括全部或部分本发明芯部包裹物基质的合适合成纤维的实施例包括,但不限于,尼龙(聚酰胺)、丙烯酸类(聚丙烯腈)、芳族聚酰胺(芳族聚酰胺)、聚烯烃(聚乙烯和聚丙烯)、聚酯、丁二烯-苯乙烯嵌段共聚物、天然橡胶、胶乳、氨纶(聚氨酯)以及它们的组合。
包含多于一种重复单元的合成纤维可通过在每个高分子串内(共聚物)、在高分子串间(共混均聚物)或它们的组合(共混共聚物),在分子水平合并重复单元产生;或者它们可以通过在较高规模水平:清晰的纳米状态、用显微镜可见的状态或肉眼可见的状态,合并重复单元产生(例如多组分纤维)。多组分纤维的每一组分可包含均聚物、共聚物或它们的共混物。双组分纤维为多组分纤维的常见形式。共聚物中的两种或多种重复单元可以被随意排列,或每种以交互嵌段形式排列。不同种类重复单元的嵌段可以在它们各自的末端互相接合(嵌段共聚物),或在至少一个嵌段的各端之间互相接合(接枝共聚物)。
无纺材料为典型地由纤维制成的呈纤维网型式的一种织物类型。无纺材料描述于1999年Butler I、Batra SK等人所著的Association of theNonwoven Fabrics Industry出版的“Nonwovens Fabrics Handbook”,和Vaughn EA所著的Association of the Nonwoven Fabrics Industry出版的“Nonwoven Fabric Sampler and Technology Reference”。
包括无纺材料的基质可通过直接挤出法形成,期间纤维和无纺材料在约同一时间点形成;或者通过预成形纤维法形成,在纤维成形之后纤维可在明显的随后时间点被铺进无纺材料中。示例性的直接挤出方法包括,但不限于:典型地形成多层的纺粘法、熔喷法、溶液纺丝、静电纺纱以及它们的组合。示例性“铺网法”包括湿法成网和干法成网。示例性干法成网方法包括但不限于典型地形成多层的气流成网、粗梳法以及它们的组合。以上方法的组合生产出一般称为混合物或复合物的无纺材料。示例性组合包括但不限于典型地呈层状的纺粘-熔喷-纺粘(SMS)、纺粘-梳理(SC)、纺粘-气流(SA)、熔喷-气流(MA)以及它们的组合。包括直接挤出在内的组合可在与直接挤出法大致同一时间点进行结合(例如,SA和MA的纺丝成型和共成型),或者在随后的时间点进行结合。在以上的实施例中,可通过每种方法产生一个或多个单层。例如,SMS可能意味着三层的“sms”无纺材料、五层的“ssmms”无纺材料,或者它们的任何合理的变化,其中小写字母表示单个层,大写字母表示类似的相邻各层的堆积。
无纺材料中的纤维典型地在某些重叠接合处被接合到一个或多个相邻的纤维。这包括在每一层内接合纤维,以及存在一层以上时在各层之间接合纤维。纤维可通过机械缠结、通过化学键合或者通过它们的组合而接合。
纤维和无纺材料可在形成后经受附加处理。对于无纺材料,附加处理通常在纤维彼此接合之后进行(后处理)。附加处理的实施例包括但不限于机械应力、化学添加剂或它们的组合。
也包括在本发明范围内的术语“芯部包裹物基质”,包括两个或多个基质或网的层压材料。市售层压材料或意图制造的层压材料也将在本发明的范围内。此外,基质可以为平坦的或具有纹理的。有纹理的基质和层压材料的不构成本发明的部分。下列讨论是为了制剂的方便,但不旨在限定本文所用的这类基质。
在本发明的一个任选实施方案中,用高能表面处理对基质进行处理。这种高能处理可以在基质用亲水性增强组合物涂敷之前或同时进行。高能处理可以为用于提高基质亲水性的任何合适的高能处理。合适的高能处理包括,但不限于,电晕放电处理、等离子处理、紫外线辐射、离子束处理、电子束处理以及它们的组合。
提高表面能量的高能表面处理在以下方面有用:与纳米颗粒联合它们可以为表面提供长久亲水属性。依次,提高的表面能可以提高基质的可湿性,不用在分散体中使用表面活性剂来达到润湿。不使用表面活性剂是有益的,理由如前文所讨论。在一个非限制性实施例中,电晕处理将瞬时电荷置于含纤维的热塑性表面上。如前面所讨论,部分或全部电荷随时间而耗散,而且在含纤维的热塑性表面上维持部分或全部电荷具有普遍的局限性。然而,据发现电晕处理与纳米颗粒联合可以用来将持久的电荷置于材料上,使得随时间的消逝水持续被吸收入材料。与高能表面处理一起使用纳米颗粒可以将此处理的瞬时属性转化为更加持久的属性。在一个非限制性实施例中,电晕处理13克/每平方米的疏水的SMS聚丙烯无纺材料,随后用亲水性增强组合物进行处理并且干燥,显示可以始终如一地快速透过随后多次涌流或排泄物。不希望受到理论的约束,电晕处理提高了纤维的表面能。不使用表面活性剂,在电荷消散之前,亲水性增强组合物被带入与纤维表面接触。较高的表面能使得分散体能够润湿纤维表面,比不经电晕处理的可能情况更好。在已润湿的表面上,纳米颗粒会结合表面上的部分或全部电荷,否则该电荷将会瞬时消逝。此结合可以采用范德华交互作用的形式或某种其它交互作用或键合的形式。纳米颗粒足够小,使得该联合足够强以经受住多次透湿。纳米颗粒足够大,以大体上阻止从氧气旋转进入聚合物或阻止散失。
纤维的机械缠结和通过化学键合,以及另外的对无纺材料的处理(诸如高能处理)的其它说明性的,但非限制性的资料,可见于共同未决的美国公布的专利申请2002/0151634(申请号:10/060,708),提交于2002年1月30日,公布于2002年10月17日,P&G档案号8408M;美国公布的专利申请2002/0192366(中请号:10/060,694),提交于2002年1月30日,公布于2002年12月19日,P&G档案号8837Q;美国公布的专利申请2002/0150678(申请号:10/060582),提交于2002年1月30日,公布于2002年10月17日,P&G档案号8838Q;美国专利申请10/338,603,提交于2003年1月8日,P&G档案号8857;以及美国专利申请10/338,610,提交于2003年1月8日,P&G档案号8858。
因为它们与基质有关的公开内容,以下专利可能被参考:1975年1月28日公布的美国专利3,862,472、1976年9月28日公布的美国专利3,982,302、1977年1月25日公布的美国专利4,004,323、1977年11月8日公布的美国专利4,057,669、1978年7月4日公布的美国专利4,097,965、1979年12月4日公布的美国专利4,176,427、1978年12月26日公布的美国专利4,130,915、1979年1月16日公布的美国专利4,135,024、1980年2月26日公布的美国专利4,189,896、1980年6月10日公布的美国专利4,207,367、1981年10月20日公布的美国专利4,296,161、1982年1月25日公布的美国专利4,309,469、1987年7月28日公布的美国专利4,682,942、以及美国专利4,637,859、5,223,096、5,240,562、5,556,509和5,580,423。
亲水性增强组合物-本发明的亲水性增强组合物包含亲水性增强量的纳米颗粒。所谓亲水性增强量意指存在于亲水性增强组合物中的纳米颗粒的量足以制造更加亲水的基质。这些量很容易由本领域的普通技术人员确定,并且基于许多因素来确定。这些因素包括但不限于所用的基质、所用的纳米颗粒、耐用亲水性芯部包裹物所需的亲水性、该吸收芯所用于的消费品等。优选地,纳米颗粒存在于亲水性增强组合物的含量按所述组合物的重量计为约0.0001%至约20%,优选约0.001%至约15%,并且更优选约0.001%至约10%。
典型地,存在于芯部包裹物基质上的亲水性增强组合物的量将随许多因素而变化。这些因素包括,但不限于,所用的基质、所用的纳米颗粒、耐用亲水性芯部包裹物所需的亲水性、该吸收芯所用于的消费品,等等。优选地,本发明芯部包裹物基质上的亲水性增强组合物的量将在约0.01克亲水性增强组合物每平方米基质(或gsm基质)和约30gsm基质之间,更优选在约0.01gsm基质和约20gsm基质之间,甚至更优选在约0.1gsm基质和约10gsm基质之间。在本发明的一个优选的实施方案中,纳米颗粒作为载体中的分散体应用到基质。
纳米颗粒为具有的粒度(即直径)为纳米大小级别的颗粒。即,纳米颗粒具有的粒度在约1纳米至约750纳米的范围内变化。这些颗粒具有重要科技意义,因为它们用来产生耐用亲水性芯部包裹物,由于它们的颗粒组分具有很小的尺寸,该芯部包裹物具有新型和有用的属性。粒度在约2纳米至约750纳米范围内变化的纳米颗粒可以经济地生产。纳米颗粒粒度分布的非限制性实施例为属于下列范围的那些:约2纳米至小于约750纳米,可供选择地约2纳米至小于约200纳米,并且可供选择地约2纳米至小于约150纳米。
纳米颗粒的粒度为纳米颗粒的最大直径。
多种纳米颗粒的平均粒度可以与纳米颗粒的颗粒粒度分布不同。例如,分层的合成硅酸盐可以具有的平均粒度为约25纳米,而它的粒度分布通常可以在约10纳米至约40纳米之间变化。(应当理解,本文所述粒度是针对分散于含水介质中的颗粒而言,并且平均粒度基于颗粒数目分布的平均值。纳米颗粒的非限制性实施例可以包括结晶的或非晶形的颗粒,这些颗粒具有的粒度为约2纳米至约750纳米。勃姆石氧化铝可以具有的平均粒度分布为约2纳米至750纳米。)
当亲水性增强组合物存在于基质上时,它将典型地为充分均匀的涂层。当亲水性增强组合物干燥时,例如任何水分蒸发掉,纳米颗粒会在基质上聚集在一起形成较大的颗粒或甚至出现薄膜的样子,这取决于所用的观测方法。在任何情况下,包括纳米颗粒的亲水性增强组合物的应用都为基质提供均匀的涂层。
有机的或无机的纳米颗粒都可用于本发明的亲水性增强组合物。合适的有机纳米颗粒包括但不限于纳米胶乳。本发明所用的“纳米胶乳”为粒度小于或等于约750纳米的胶乳。“胶乳”为水不溶性的聚合物颗粒的胶态分散体,通常呈球状。纳米胶乳可通过乳液聚合作用来形成。“乳液聚合作用”为利用表面活性剂将胶乳分散进水中以形成稳定的乳液,并继之进行聚合反应的一种方法。所产生颗粒的尺寸范围为约2纳米至约600纳米。
虽然有机纳米颗粒在本发明的范围内,但是无机纳米颗粒是优选的。无机纳米颗粒通常作为氧化物、硅酸盐、碳酸盐和氢氧化物存在。某些分层的粘土矿物和无机金属氧化物可以为纳米颗粒的实施例。适用于本发明的层状粘土矿物包括在绿土、高岭土、伊利石、亚氯酸、绿坡缕石和混合的层粘土的地质类别中的那些矿物。属于这些种类的具体粘土的典型实施例为绿土、高岭土、伊利石、亚氯酸、绿坡缕石和混合的层粘土。例如,绿土包括蒙脱石、膨润土、叶蜡石、锂蒙脱石、滑石粉、锌蒙脱石、囊脱石、滑石、贝得石、铬高岭石和蛭石。高岭土包括高岭石、地开石、珍珠陶土、叶蛇纹石、蠕陶土、多水高岭土、indellite和温石绒。伊利石包括漂云母、白云母、钠云母、金云母和黑云母。亚氯酸包括绿泥间蛭石、叶绿泥石、片硅铝石、须藤石、叶绿泥石和斜绿泥石。绿坡缕石包括海泡石和polygorskyte。混合的层粘土包括钠板石和黑云母蛭石。这些层状粘土矿物的变体和同构取代体提供了独特的应用。
层状粘土矿物可以是天然存在的或是合成的。涂层组合物的一个非限制性实施方案的实施例使用天然的或合成的锂蒙脱石、蒙脱石和膨润土。另一个实施方案使用市售的锂蒙脱石粘土,并且商业锂蒙脱石的典型来源为购自Southern Clay Products,Inc.,U.S.A的LAPONITEsTM、购自R.T.Vanderbilt,U.S.A的Veegum Pro and Veegum F和购自Baroid Division,National Read Comp.U.S.A的Barasyms、Macaloids和Propaloids。
在本发明的一个优选的实施方案中,纳米颗粒包括合成的锂蒙脱石,硅酸锂镁。一个这样合适的硅酸锂镁为LAPONITETM,它具有以下化学式:
               [MgwLixSi8O20OH4-yFy]z-
其中w=3至6,x=0至3,y=0至4,z=12-2w-x,并且总的负点阵电荷通过抗衡离子进行平衡;并且其中抗衡离子选自精选的Na+、K+、NH4 +、Cs+、Li+、Mg++、Ca++、Ba++、N(CH3)4 +,以及它们的混合物。(如果LAPONITETM用阳离子有机化合物进行“改性”,那么“抗衡离子”会被看作是任何阳离子有机基团(R))。
其它合适的合成锂蒙脱石包括但不限于同晶形取代的LAPONITETM,诸如LAPONITE BTM、LAPONITE STM、LAPONITE XLSTM、LAPONITE RDTM、LAPONITE XLGTM和LAPONITE RDSTM
纳米颗粒也可以为其它无机材料,包括无机氧化物,例如,但不限于,氧化钛、二氧化硅、氧化锆、氧化铝、氧化镁,以及它们的组合。其它合适的无机氧化物包括氧化铝和二氧化硅的多种无机氧化物。

典型使用在本组合物中的任选成分(当存在时)的含量按所述组合物的重量计为约0.001%至约99.9%,优选约0.01%至约98%,更优选约0.1%至约96%。
合适的载体包括液体、固体和气体。一个优选的载体为水,所述水可以为蒸馏水、去离子水或自来水。由于水的低成本、实用性、安全性和相容性等特点,水是有用的。
任选地,除了水之外或代替水,载体也可以包括低分子量有机溶剂。优选地,该溶剂高度可溶于水,例如乙醇、甲醇、丙酮、乙二醇、丙醇、异丙醇等以及它们的混合物。低分子量醇可以减小纳米颗粒分布的表面张力,以提高基质的可润湿性。当基质为疏水基质时尤其有用。低分子量醇也可以有助于使处理过的基质更快干燥。任选的水溶性低分子量溶剂可以任何合适的含量使用。载体可包括任何合适量的组合物,所述合适量按重量计包括但不限于约10%至约99%,可供选择地约30%至约95%的所述涂层组合物。
在本发明的某些实施方案中,表面活性剂为一个任选成分。表面活性剂在涂层组合物尤其适用作润湿剂,以促进纳米颗粒在基质上的分散。当涂层组合物用于处理疏水基质时,优选包括表面活性剂。
合适的表面添加剂可选自以下物质,包括阴离子表面活性剂、阳离子表面活性剂、非离子表面活性剂、两性表面活性剂、两性的表面活性剂、两性离子表面活性剂以及它们的混合物。用于本发明组合物的表面活性剂的非限制性实施例公开于Allured Publishing Corporation出版的McCutcheon的“Detergents and Emulsifiers”,North American edition(1986);McCutcheon的“Functional Materials”,North American Edition(1992);和美国专利5,707,950和5,576,282;和1975年12月30日公布的授予Laughlin等人的美国专利3,929,678。
当将表面活性剂用于涂层组合物时,它可按有效量添加以促进涂层组合物的应用。典型使用在本组合物中的表面活性剂(当存在时)的含量按所述组合物的重量计为约0.0001%至约60%,优选约0.001%至约35%,更优选约0.001%至约25%。
表面活性剂(包括优选的非离子表面活性剂,典型用于本文的含量按重量计为约0.001%至约60%)的非限制性实施例,包括非离子表面活性剂和两性表面活性剂,例如包括称为窄峰烷基乙氧基化物C12-C18烷基乙氧基化物(“AE”)和C6-C12烷基酚烷氧基化物(尤其是乙氧基化和混合的乙氧基/丙氧基)、C12-C18甜菜碱和磺基甜菜碱(“磺基甜菜碱”)、C10-C18氧化胺,等等。
另一类有用的表面活性剂为硅氧烷表面活性剂和/或硅氧烷。它们可单独使用和/或可供选择地与本文所述的烷基乙氧基化物表面活性剂联合使用。硅氧烷表面活性剂的非限制性实施例为具有二甲基聚硅氧烷疏水部分和一个或多个亲水聚亚烷基侧链的聚亚烷基氧化物聚硅氧烷,并具有如下通式:
R1-(CH3)2SiO-[(CH3)2SiO]a-[(CH3)(R1)SiO]b-Si(CH3)2-R1
其中a+b为约1至约50,并且每个R1是相同的或不同的,并且选自甲基和具有以下通式的聚(环氧乙烷/氧化丙烯)共聚物基团:-(CH2)nO(C2H4O)c(C3H6O)dR2,其中n为3或4;全部c(对于所有聚亚烷基氧侧基团)具有1至约100的值,可供选择地约6至约100;全部d为0至约14;可供选择地d为0;全部c+d具有约5至约150的值,可供选择地约9至约100,并且每个R2是相同的或不同的,并且选自氢、含有1个至4个碳原子的烷基,及乙酰基,可供选择地为氢和甲基。每个聚环氧烷聚硅氧烷具有至少一个为聚(环氧乙烷/氧化丙烯))共聚物基团的R1基团。硅氧烷超润湿剂作为硅氧烷乙二醇共聚物(例如,Q2-5211和Q2-5212)购自Dow Corning。
使用表面活性剂的混合物也在本发明的范围内。
辅助成分-组合物可以包含其它任选辅助成分,包括但不限于加工助剂、抗微生物的防腐剂、抗氧化剂、抗静电剂、螯合剂、着色剂、染料、填充剂盐、杀真菌剂、除昆虫和蛀虫剂、杀菌剂、水溶助长剂、金属盐。这些任选成分可以任何所需的含量被包括,但典型加入的含量按所述组合物的重量计为约0.0001%至约99.99%。
将亲水性增强组合物应用至基质-亲水性增强组合物可以任何适当的方式应用至基质。亲水性增强组合物可以在基质至少部分浸没在组合物浴中时应用至基质(浸没方法),或者不用将基质浸没在涂层组合物中时应用至基质(非浸没方法)。
在本发明的一个实施方案中,亲水性增强组合物通过轻触辊式涂敷来应用。在轻触辊式涂敷中,组合物被放在合适的浴中。一个适于此方法的滚筒或任何其它装置至少用其表面的一部分接触组合物。这样,组合物被涂敷在滚筒的表面上。在滚筒表面已经涂敷有组合物时,使基质与滚筒接触。在这个方法中,可以容易地控制应用到基质上的组合物的量,并且可能避免基质被组合物浸透。
相对于轻触辊式涂敷,组合物也可被可供选择地喷射在多个纤维的表面上。象轻触辊式涂敷一样,喷射能够降低并且容易控制水溶液的添加含量,其在本发明中为优选的。其它可供选择的方法包括,但不限于,印刷,例如旋转印刷、凹版印刷、柔性版印刷、喷墨印刷、槽式涂敷印刷等。
制造一次性吸收制品的方法-图7图示说明生产一次性吸收制品的一个任选的实施方案,更具体地讲,生产吸收芯的步骤。耐用亲水性芯部包裹物42从分配辊110分配到输送带120上。耐用亲水性芯部包裹物42预先通过用亲水性增强组合物涂敷基质来形成。耐用亲水性芯部包裹物42沿输送带120移动至点130,在该点存储层60的组分从料斗140和150分配。从料斗150分配的透气毡160,在沉积到亲水的芯部包裹物42上之前,在点130与吸收剂胶凝材料170混合。
在170阶段,部分存储层60被耐用亲水性芯部包裹物42所围绕。围绕存储层60的实施例,例如胶囊包封或包裹,这可以在本文所述的关于图2至6的内容中找到。最后,在阶段180,耐用亲水性芯部包裹物42的末端被密封。合适的密封方法包括,但不限于,粘合、加热、超声波以及它们的组合。然后形成的吸收芯可以被进一步加工,以将它并入一次性吸收制品,例如位于一次性尿布的顶片和底片之间。

测试方法-除非另外声明,所有试验均在标准实验室条件(50%湿度和在23℃(73°F))下进行。
接触角-采用First Ten Angstroms,USA制造的FTA200动态接触角分析器测量动态接触角。在样本基质上滴一滴测试溶液。当该液滴沿着底物表面铺开时进行数字视频记录,并且FTA200软件测量作为时间函数的液体与底物的接触角。
表面张力的测定-表面张力(单位:mN/m)根据下列试验进行测定。装置:设备:德国Krüss GmbH或同类公司提供的K10张力计。容器升高速度应该为4毫米/分钟。当使用板或环时,应该自动地感测液面高度。设备必须能够自动地将样本位置调节到正确的高度。测试的精度应为+/-0.1mN/m。
过程(i)校准:将40mL的盐水(0.9%重量的NaCl去离子水溶液)倒入一个干净的烧杯中。使用设备说明中所述的方法,用铂环或铂板测试盐水的表面张力。在20℃下,表面张力应为71mN/m至72mN/m。
(ii)方法:用去离子水和异丙醇清洗烧杯,包括用煤气灶灼烧几秒。等待,直到达到烧杯温度平衡至室温。将十片60×60mm的测试无纺材料放入清洗过的烧杯中。无纺材料应该具有的定量至少为约10克/每平方米(或gsm)。加入40mL盐水(0.9%重量的NaCl去离子水溶液),并且用清洁的无表面活性剂的塑性棒手动搅拌10秒。让装有无纺材料的溶液静置5分钟。再手动搅拌10秒。用一根干净的无表面活性剂的塑料棒从盐水中取出无纺材料。让溶液静置十分钟。然后使用设备说明中所述的方法,用铂环或铂板测试液体的表面张力。所测的表面张力为冲掉表面张力。
液体透湿试验-使用Lenzing AG,Austria制造的Lister型透湿仪器测量液体透湿时间。试验过程基于标准的EDANA(European DisposablesAnd Nonwovens Association)方法150.3-96,将测试样本放置在由十层滤纸(从Empirical Manufacturing Co.,Inc.USA购买的Ahlstrom Grade 632或者等价物)构成的吸收垫上。在一个典型的实验中,不用换吸收垫,以一分钟的间隔将三次连续涌出的5ml测试液体(0.9%盐水溶液)应用到无纺材料样本上,并且记录下各自的透湿时间。
除了按Edana Method所述测定第一涌流的透湿时间之外,下述试验不仅测定第一涌流,而且测定随后的几次涌流,尤其是第五涌流。
装置-Lister透湿设备-(i)装有电磁阀的漏斗:排放速率为3.5(±0.25)秒内排放25mL;(ii)透湿板:制作25mm厚的丙烯酸玻璃。板的总重必须为500g。电极应为抗蚀材料。将电极嵌入在板的底部切削出的截面为(4.0mm×7.0mm)的凹槽中,并且用快干环氧树脂固定。图8、9和10图示说明包含电极210的透湿板200。图8为透湿板200的顶视图,而图9为图8的透湿板200沿9-9的剖面图。图10为图8的透湿板200沿10-10的剖面透视图;(iii)基板:大约125mm×125mm的正方形丙烯酸玻璃;(iv)支撑漏斗的环架;(v)测量至0.01秒的电子定时器;(vi)50mL容量的滴定管;和(vii)Ahlstrm Grade 989的芯滤纸或等价物(平均透湿时间1.7s+-0.3s,尺寸:10×10cm)。
步骤:(1)仅在样本边缘接触样本,小心地切割所需数量的12.5cm×12.5cm的样本。(2)取10层芯滤纸,在基板上将一个样本放在这套10层滤纸上。样本应该以这样一种方式放置在滤纸上:用来朝向使用者皮肤的无纺材料侧(当应用于吸收制品时)在最上面。(3)将透湿板放在顶部,使板的中心位于试样中心的上方。使滴定管和漏斗在板上方居中。(4)确保电极与定时器连接,接通定时器并且将时钟设定为零。(5)用盐水溶液(0.9%重量的NaCl去离子水溶液)装满滴定管。(6)保持漏斗的排出阀关闭,并且从滴定管滴入漏斗5.0mL液体(等于一次涌流)。(7)打开漏斗的电磁阀,排出5.0mL的液体。初始液体流将接通电路并启动定时器。它将在液体已经渗入垫并降到透湿板中电极的平面之下时停止。(8)记录电子定时器上所显示的时间。(9)等待60秒并且重复步骤(4)和(6)至(9),进行第二次、第三次涌流和任何随后的涌流,其中每次涌流包括5ml液体。(例如,5ml进入漏斗,打开电磁阀,等等)用秒记录第1第2和任何随后涌流的时间。
