具体实施方式
本发明涉及具有高耐磨性和优异的悬垂性和柔韧性的图案化非织造幅材及其制造方法。在本发明中，非织造幅材的耐磨性和悬垂性至少部分取决于用于将连续纺熔长丝、梳理纤维或长丝和纤维的组合粘合在一起的熔结图案(其中多个幅材被结合在一起)，使得得到的非织造物是耐磨的，但仍然柔软且柔韧。
在实施方式中，粘合图案可以包括具有几何形状或不规则形状的闭合图形，通过未粘合区域彼此至少部分地分开。为了本公开的目的，术语“闭合图形”旨在意指由连续或不连续的粘合线限定的未粘合纤维区域。在示例性实施方式中，粘合图案可以由网格线构成，使得在构成图案的重复图形之间不存在空隙。粘合图案还可以包括附加的粘合元件，诸如点或线。图案优选将沿着长丝和纤维纵向延伸的离散部分或区段内非织造物中的全部或几乎全部长丝或纤维粘合在一起。图案化非织造物优选耐磨的，使得非织造物在被另一种材料或穿用者磨损时不会显着降解(degrade)。本文所用的“耐磨性”是指“非织造物抵抗由与穿用者或与其他材料的平面摩擦接触引起的表面磨损的能力”。同时，非织造物保持柔软且柔韧。
使用根据本发明的粘合图案形成的非织造幅材特别适用于一次性吸收性制品。如本文所用，术语“吸收性制品”是指吸收并容纳流体和固体材料的制品。例如，吸收性制品可以靠着或靠近身体放置以吸收和容纳由身体排出的各种排出物。吸收性制品可以是穿着制品，诸如婴儿尿布、成人失禁产品和女性护理产品，或用于吸收流体和固体材料的卫生产品，诸如用于医疗行业，具体实例是一次性罩衣和夹头。非织造物还可以用于包装或包装物品，诸如吸收性制品。术语“一次性”在本文中用于描述吸收性制品，其不打算清洗或以其他方式作为吸收性制品恢复或再利用，而是打算在一次使用后丢弃，并且优选地被回收、堆肥或以环境相容的其他方式处理。
图1示出了在非织造幅材上形成的粘合图案的示例性实施方式的透视图，该非织造幅材已经被确定实现具有高耐磨性和强度，同时保持非织造物中期望的柔软性和柔韧性的非织造物。在图2中附接到吸收性制品诸如尿布的基体的非织造幅材的背景下示出了图1的粘合图案。例如，非织造幅材可以是如图2所示的尿布顶片中的层。可替代地，例如，非织造幅材可以是尿布的膜/非织造物复合底片的外层，如图3所示。
已经发现希望由布置成闭合图形的连续粘合线形成粘合图案，因为这使得非织造幅材在保持柔韧性的同时具有提高的耐磨性。不受理论约束，据信将闭合图形放置在交错位置可以最小化未粘合的松散纤维或长丝端头，从而提高耐磨性。这种闭合图形的优选实施方式是圆圈或其他圆形图形，但也可以使用其他图形，诸如多边形或形状组合。
闭合图形还可以与其他类型的粘合联用，诸如点粘合或粘合线。这些附加元件可以置于闭合图形内。此外，附加的粘合可以用于装饰或美学目的。就此而言，可以通过与用于闭合图形的粘合方法不同的粘合方法来形成附加粘合。这些元件被设计成不会显著影响非织造物的柔软度和悬垂性。在另一种替代方式中，可以使用压花来代替附加的粘合。在至少一种实施方式中，可以应用辅助图案(诸如孔的图案)，在基本上不会降低非织造物的悬垂性的情况下提供功能、装饰和/或美学效益。辅助图案可以与闭合图形的图案套准。可替代地，辅助图案可以在不套准闭合图形的图案的情况下应用。
图4是用于形成根据本发明示例性实施方案的图案化非织造幅材的系统(通常用附图标记6表示)的代表图，其中形成了纺粘、熔喷或纺粘-熔喷-纺粘复合(“SMS”)非织造物。该方法始于由本领域熟知的工艺形成的连续纤维的非织造幅材。在所示的示例性实施方式中，幅材优选是“熔纺”的，即，非织造幅材是熔喷、纺粘或其组合。在优选的实施方式中，用于形成幅材的纤维是热塑性或可纺的聚合物，其实例包括聚烯烃、聚酯、聚酰胺、其共聚物(与烯烃、酯、酰胺或其它单体)及其共混物。如本文所用，术语“共混物”包括至少两种聚合物的均匀混合物或至少两种物理上不同的聚合物的非均匀混合物，正如用于优选布置或组合成皮芯结构或并列结构的双组分纤维或长丝。优选纤维是聚烯烃，其实例包括聚乙烯、聚丙烯、其丙烯-丁烯共聚物及其共混物，包括例如乙烯/丙烯共聚物和聚乙烯/聚丙烯共混物。在甚至更优选的实施方式中，纤维是双组分或多组分纤维。根据示例性实施方式，纤维是线性质量密度在1.1至5.0旦范围内的聚丙烯纤维，并且在优选实施方式中，线性质量密度在1.1至2.5旦范围内，并且在另一种优选实施方式中，线性质量密度在1.1至1.8旦的范围内。可替代地使用线性质量密度大于或小于1.8旦的纤维。
如图4所示，根据本发明的示例性实施方式的纺熔非织造幅材10由连续长丝12制成，该连续长丝以随机分布的方式铺设在移动的传送带14上。在典型的纺熔工艺中，树脂粒料在加热下加工成熔体，然后通过喷丝头给料，以通过使用拉伸装置16产生数百根长丝12。可使用多个喷丝头或经轴以提供增加密度的纺粘纤维。尽管图4示出了使用三个经轴，但可以使用任何数量的经轴，例如两个或四个经轴。流体(诸如空气)的射流引起纤维12拉长，然后纤维12被吹送或携带到移动的多孔带14上，在那里它们铺设在多孔带上并被抽吸箱18以随机模式相对多孔带14抽吸以产生织物结构8。
典型的热粘合工段20包括具有限定粘合图案的粘合辊24的压延机22。可替代地，热粘合工段20可以具有超声装置或使用高温空气的通气粘合装置，空气的温度足够高以通过熔化熔融温度较低的聚合物组分以引起长丝和/或纤维之间在其相交部分的热粘合。
来自布置成闭合图形的粘合线的粘合图案可以在热粘合期间在工段20处使用，因为这将导致形成具有提高的耐磨性同时保持柔韧性的非织造幅材。例如，图1中所示的圆圈的示例性图案可以根据本发明在热粘合期间形成，诸如在工段20处。在优选实施方式中，图1的粘合图案100包括直径范围为5-15mm，且更优选直径为10mm的圆圈110。如果使用短的(即不连续的)纤维来形成非织造物，则纤维长度优选是构成图案的闭合图形最大直径的两倍。在该实施方式中，圆圈具有在0.3mm至1.5mm范围内，且更优选为0.4mm至0.8mm的粘合线宽度。如图7A-7C所示，图案内的相邻圆圈可以被布置成使得相邻圆圈沿公共切线彼此接触(图7A)、相邻的圆圈重叠(图7B)和/或相邻的圆圈之间间隔一些距离(图7C)。此外，如图8所示，圆圈可以布置成交错列，与相邻列内的圆圈相比一列内的圆圈具有不同的直径。不受理论约束，据信这样的布置能粘合非织造物中全部或几乎全部长丝或纤维，并且有效地将纤维的自由端连紧，由此提供耐磨性。在使用纺粘非织造物的示例性实施方式中，相邻交错圆圈之间的最小距离可以在2.0至3.5mm之间的范围内，并且更优选最小距离为3mm。此外，粘合面积的总百分比，即粘合线宽度与非粘合区域的比率，在5至30％之间，更优选在10至25％之间，并且甚至更优选地为约14％。粘合辊表面上的凸刻深度在0.2mm至1.2mm的范围内，且更优选为1mm。
如图9A和图9B所示，可以相对于孔120的辅助图案来布置圆圈110(或其他闭合的粘合线形状)。孔120可以与圆圈110套准(图9A)或者不与圆圈110套准(图9B)。孔120可以由液压、机械或通过任何其他工艺形成。
在热粘合之后，在示例性实施方式中，非织造幅材10可以进行水刺处理(hydraulically treated)，诸如经由水刺缠结(hydroentanglement)或水刺嵌入(hydroengorgement)。在优选的实施方式中，非织造幅材10经受水刺嵌入。水刺处理可以以单个步骤或以两个或更多个分开的步骤来进行。如果非织造幅材10经过水刺处理，则非织造幅材10随后进行脱水。脱水可以包括抽吸箱，当非织造幅材10在脱水线上行进时抽吸箱将水从非织造幅材10中抽出。然后，在将精加工材料在卷绕工段卷取并转化(converted)之前，将非织造幅材10送到干燥工段进行干燥。干燥可以通过将热空气吹过纤维幅材、通过IR干燥器或其他干燥技术来进行。
在转化(conversion)之前，可以对非织造幅材10进行处理，诸如电晕或等离子体处理、用任何所需类型的局部化学物质处理等。电晕或等离子体处理优选在干燥幅材上进行，而局部化学物质可以优选在幅材脱水后以水溶液通过喷雾、印刷等添加。
非织造幅材10可以并入到非织造层合物中。非织造层合物可以包括连续纤维(诸如纺粘纤维和熔喷纤维)的附加层，并且可以包括复合非织造物，诸如纺粘-熔喷-纺粘层合物。非织造层合物还可以包括短纤维(short fibers)(诸如短纤)或可以包括纸浆纤维。这些短纤维可以是固结幅材的形式，诸如梳理幅材或绵纸片，或者可以是最初未固结的。非织造层合物还可以包括以颗粒形式或纤维化形式的超吸收材料。层合物可以通过常规方法形成，包括但不限于热粘合、超声波粘合、化学粘合、粘合剂粘合和/或水刺缠结。
非织造幅材10与棉纤维层合并以形成复合幅材，棉纤维构成复合幅材的5％至30％。
在示例性实施方式中，如果构成粘合图案的圆圈内的面积为20mm2或更小，则圆圈内的面积与形成圆圈的粘合线宽度之间的比率在20至200的范围内。如果圆圈内的面积为从20mm2至100mm2，则圆圈内的面积与形成圆圈的粘和线宽度之间的比率在50至400的范围内。如果圆圈内的面积为从100mm2到1000mm2，则圆圈内的面积与形成圆圈的粘和线宽度之间的比率在100至1000的范围内。
在示例性实施方式中，如果环绕区域的直径或长丝/纤维穿过环绕区域的最大可能长度为5mm或更小，则直径或长丝/纤维的最大可能长度与粘合线宽度之间的比率在10至50的范围内。如果环绕区域的直径或长丝/纤维穿过环绕区域的最大可能长度为5mm至10mm，则直径或长丝/纤维的最大可能长度与粘合线宽度之间的比率在10至100的范围内。如果环绕区域的直径或长丝/纤维穿过环绕区域的最大可能长度为10mm至15mm，则直径或长丝/纤维的最大可能长度与粘合线宽度之间的比率在10至150的范围内
在形成圆圈的粘合线不连续的示例性实施方式中，与粘合线的总体方向一致的线中断或间隙在0.1mm至3.0mm的范围内，更优选地在0.1mm至1.0mm范围内。粘合线的未中断部分与线性间隙延伸部分之间的比率优选在5至50的范围内。
使用以下测试方法以获得本文提供的数据。
磨损测试
新型马丁代尔磨损(NuMartindale Abrasion)是对织物样品表面耐磨性的量度，并且根据ASTM D 4966-98进行，在此通过引用将其并入本文。使用马丁代尔磨损和起球试验机(Martindale Abrasion and Pilling Tester)对每个样品进行新型马丁代尔磨损测试，每个样品进行40到80次磨损循环。在完成所有磨损循环或测试样品破坏后报告测试结果。优选地，材料表面不应该有视觉变化。
对于每个样品，在新型马丁代尔磨损之后，基于1至5的视觉评定等级确定磨损等级，等级定义如下：
5＝优秀＝从结构中去除的纤维非常少至零。
4＝非常好＝少量的纤维可能以丸或脱线的形式。
3＝一般＝中等量的纤维以及大脱线或多脱线。
2＝差＝大量的松散脱线，可以很容易地去除。
1＝非常差＝显著的结构失效，洞，大的松散脱线很容易被去除。
柔软度测试
通过由Thwing Albert of West Berlin,NJ制造的织物手感测定仪(Handle-O-Meter)使用Method INDA IST 90.3-01测试方法和100mm×100mm的样品尺寸进行柔软度测试，且结果没有加倍。该装置可测量片状材料(诸如非织造幅材)的柔韧性和表面摩擦力。对每个样品在机器方向(machine direction)和横向(cross direction)两个方向进行测试。在进行测试时，可以使用6.4mm宽的槽口。捕获峰值负载并以克为单位记录。
粘合压痕的图像分析
使用能够以反射模式以至少4800dpi的分辨率扫描的平板扫描仪(适合的扫描仪是Epson Perfection V750Pro,Epson,USA)产生的图像进行面积和距离测量。使用ImageJ软件进行分析(Vs.1.43u,National Institutes of Health,USA)，并使用经NIST认证的标尺进行校准。
为了获得与吸收性制品一起使用的非织造物的样本，将吸收性制品的样品平放在工作台上，面向身体的表面向下，并测量制品的总纵向长度。标记距吸收性制品的前缘沿纵向轴33％总长度处和距吸收性制品的后缘33％总长度的第二位点。小心地从吸收性制品上移除非织造物。使用低温喷雾诸如Cyto-Freeze(得自Control Company,Houston,TX)将非织造物从下层中分离。
对于每个样本，切割80mm×80mm的片。对于从吸收性制品上移除的非织造物，以上述确认的每个位点为中心切割80mm×80mm的样本。在测试之前，将样品在约23℃±2℃和约50％±2％相对湿度下预处理2小时。
将样本放置在平板扫描仪上，分析面朝下，标尺直接与其相邻。该放置使得对应于非织造物MD的尺寸与标尺平行。将黑色衬垫放置在样本上，并关闭扫描仪的盖子。在8位灰度的反射模式下以4800dpi的分辨率获取包括非织造物和标尺的图像并保存文件。打开图像文件并使用图像化标尺进行线性校准。这些测量同样适用于其他粘合形状和重复粘合图案。
粘合面积百分比
非织造幅材上的“粘合面积百分比”是由粘合压痕占据的面积与幅材的总表面积的比率，以百分比表示，并且根据列于本文的粘合面积百分比方法测量。在美国专利No.8,841,507中描述了用于测量粘合面积百分比的方法，该专利通过引用并入本文。
以下实施例和对比例说明了本发明的优点。
实施例1
实施例1是由聚丙烯制成的与图1中所示粘合图案热粘合的21.3gsm纺粘非织造幅材，具有约14％的粘合面积百分。
对比例1
对比例1是由聚丙烯制成的并且与图5中所示开放式粘合图案热粘合的20.2gsm纺粘非织造幅材，具有约14％的粘合面积百分比。
对比例2
对比例2是由聚丙烯制成的并且与图6中所示封闭粘合图案热粘合的21.8gsm纺粘非织造幅材，具有约18％的粘合面积百分比。
表I示出了对实施例1、对比例1和对比例2进行的测试结果之间的比较。如前所述，发现实施例1具有优秀的耐磨性，但是具有类似粘合面积百分比的对比例1则没有。而对比例2也具有良好的耐磨性质，但是其具有显著低于实施例1的悬垂性。
结果显示实施例1的图案提供了优秀的耐磨性和悬垂性。因此，使用闭合粘合图案将纺粘非织造物的纤维粘合在一起是有利的。
