Description

改进的紧固带
技术领域
本发明涉及包括紧固元件的紧固带领域，其可以用于例如卫生产品(hygieneproducts)领域或健康和医疗产品(health and medical products)领域以及其他可能的应用。
背景技术
紧固带或钩带(hook tape，粘扣带)通常包括由非织造材料，例如纺粘非织造材料(spunbond nonwoven material)制成的基材层。该基材的一面设置有聚丙烯涂层，另一面设置有硅涂层。在聚丙烯涂层的一部分上设置有粘合剂层，并且在该粘合剂层的一部分上设有钩元件。聚丙烯涂层旨在保护粘合剂层免受硅涂层可能迁移而通过非织造材料的影响。
然而，添加此类聚丙烯涂层存在多个缺点。首先，提供聚丙烯涂层的成本很高，并且必须对聚丙烯层进行电晕处理(corona treatment)，以确保粘合剂层的附着力。此外，聚丙烯增加了带的刚度并且影响了产品的外观，这两种情况都应该避免。
因此，本发明旨在为这些问题至少提供部分解决方案。
发明内容
为了至少部分地解决上述问题，本发明涉及一种紧固带，包括：
基材层，其包括非织造层，所述非织造层具有限定所述基材层的第一外面和第二外面的两个相对的面；以及
至少一个紧固元件，被设置在所述基材层的第一外面上，
所述紧固带的特征在于，按照ISO 9237，在200Pa压力下，对于具有8mm直径的受测区域(相当于50.27mm2的圆形表面)的样本而言，所述基材具有高于0且低于30l.m-2.s-1，或低于25l.m-2.s-1，或低于15l.m-2.s-1，或低于12.8l.m-2.s-1的透气性(air permeability，透气率)，或者，按照ISO 9237，在200Pa压力下，对于具有20cm2面积的受测区域的样本而言，所述基材具有高于0且低于1200l.m-2.s-1，或低于1000l.m-2.s-1，或低于600l.m-2.s-1，或低于509l.m-2.s-1的透气性。因此，由于这些特征，所述紧固带具有使空气不渗透的特性，该特性足以使得紧固带能够在例如用于婴儿尿布和/或成人失禁尿布的装配/生产线上被抓取。
根据示例实施例，按照ISO 9237，在200Pa压力下，对于具有8mm直径的受测区域(相当于50.27mm2的圆形表面)的样本而言，所述基材具有高于0.1且低于10l.m-2.s-1的透气性，或者，按照ISO 9237，在200Pa压力下，对于具有20cm2面积的受测区域的样本而言，所述基材具有高于4且低于398l.m-2.s-1的透气性。
根据示例实施例，所述非织造层包括直径小于0.02mm，或优选地小于0.01mm，更具体地小于0.005mm的纤维和/或细丝。
根据示例实施例，按照ISO 9237，在200Pa压力下，对于具有8mm直径的受测区域的样本而言，所述基材层的渗透性与所述非织造层的表面重量之间的乘积小于1800g.l.m- 4.s-1，或小于1500g.l.m-4.s-1，或小于800g.l.m-4.s-1，特别地小于400g.l.m-4.s-1。所述基材层的渗透性与所述非织造层的重量之间的乘积通常也高于零。
根据示例实施例，所述非织造层包括至少一层熔喷材料和/或至少一层纺粘材料。另外，所述非织造层可以包括至少一层被布置在至少两层纺粘材料之间的熔喷材料。
根据示例实施例，所述基材层的第二外面包括硅酮涂层(silicone coating，有机硅涂层)。
根据示例实施例，在所述基材层的第一外面上设置有粘合剂层。
根据示例实施例，所述紧固元件至少包括钩和/或杆，特别是多个钩和/或多个杆。
根据示例实施例，保持元件的高度介于5与5000微米之间，更具体地介于5与2000微米之间，或更具体地介于20与800微米之间，在与基部的上表面垂直的方向上测量该高度。
根据示例实施例，所述紧固元件通过直接层叠(direct lamination)被结合到所述基材层的第一外面。根据示例，所述紧固元件可以包括基部和至少从基部的一个面突出的钩和/或杆，特别是多个钩和/或多个杆。基材层的作为非织造物的纤维和/或细丝的某些部分可以被封装到基部和/或直接从基部的另一(相对的)面延伸出来的一些纤维和/或细丝中。
根据示例实施例，紧固元件如文献WO2017187096 A1中所述，该文献通过引用并入本文，并且在考虑本公开时可以被参考。
根据示例实施例，所述基材层的基重介于5gsm与100gsm之间，特别地介于25gsm与65gsm之间。

在所有附图中，共同的元件由相同的附图标记来表示。
具体实施方式
根据本公开的示例实施例的紧固带在图1中被示出。
图1中所示的紧固带1包括：基材层2；以及至少一个紧固元件3，该紧固元件设置在基材层2的一个外表面上。
基材层2例如由呈带状的非织造层制成，并且具有限定第一外面2A和第二外面2B的两个相对的面。在图1所示的示例中，紧固元件3被布置在基材层2的第一外面2A上。
紧固元件3可以例如包括基部31和至少一个诸如钩和/或杆(stem)的保持元件32，或者包括从基部延伸的杆的更一般的元件，和布置在该杆的顶部上的头部，该头部被配置为与另一类似的保持元件32和/或环和/或非织造材料配合，来限定能释放的紧固。
非织造物(nonwoven)是一种通过将已经固结的纤维和/或细丝(filament)形成网而获得的产品。固结(consolidation)可以是机械的、化学的或热导的，并导致纤维和/或细丝之间存在结合(bond)。这种固结可以是直接的，即通过熔接(welding，焊接)直接在纤维和/或细丝之间进行，或者其也可以是间接的，即通过纤维和/或细丝之间的中间层，例如粘合剂层或粘结剂层(binder layer)。术语非织造物是指以不均匀、不规则或随机的方式交织(intertwine)的纤维和/或细丝的带状结构或网。非织造物可以具有单层结构或多层结构。非织造布也可以与另一种材料组合形成层压材料(laminate)。非织造物可以由不同的合成和/或天然材料制成。天然材料的示例为诸如棉(cotton)、黄麻(jute)、亚麻(flax)等纤维素纤维(cellulose fibres)，并且还可以包括诸如人造纤维(rayon)或粘胶纤维(viscose)等再生纤维素纤维。用于非织造材料(non-woven material)的天然纤维可以采用各种工艺，诸如梳理(carding)制备。合成材料的示例包括但不限于合成塑料聚合物，已知其被用于形成纤维，这些纤维包括但不限于：聚烯烃，例如聚乙烯、聚丙烯、聚丁烯及类似物；聚酰胺，例如聚酰胺6、聚酰胺6.6、聚酰胺10、聚酰胺12及类似物；聚酯，例如聚对苯二甲酸乙二醇酯、聚对苯二甲酸丁二醇酯、聚乳酸及类似物、聚碳酸酯、聚苯乙烯、热塑性弹性体、聚合乙烯基、聚氨酯及其混合物和共聚物。例如，非织造物可以是诸如纺粘(Spunbond)、纺熔(Spunmelt)、热粘合梳理(thermally bonded carded)、SMS、SMMS、SS、SSS、SSMMS、SSMMS、SSMMMS、热风(Air through，热风法)非织造物或其他的非织造物。给出这些示例但不限于此。我们也可以使用具有纳米纤维层(nanofibers layer)的非织造物，该纳米纤维层例如通过熔喷技术(meltblown technology)或静电纺丝技术(electrospinningtechnology)的工艺而生产。
按照1995年8月出版的法国和欧洲法规NF EN ISO 9237(ISSN0335-3931)中定义的测量方法，具有一测量表面，该测量表面具有直径为8mm和压力为200Pa的圆盘形状，基材层2具有高于0且低于30l.m-2.s-1，或更精确地低于25l.m-2.s-1，或例如低于15l.m-2.s-1，或更精确地低于12.8l.m-2.s-1的透气性。
由于紧固带1的一些预期应用(例如应用在尿布上)，这将导致紧固带1的部分尺寸小，因此受测面积减小到8mm直径的圆盘(即面积约为0.50cm2)。图4和图5示出了适配器100的示例，以在具有8mm直径的受测区域的样本上进行法国和欧洲法规NF EN ISO 9237中所定义的测量。
所示适配器100包括两个部分：上部110和下部120，其通过铰链(hinge，合页)130连接。上部110具有内面110i和外面110o。下部120具有内面120i和外面120o。当适配器闭合时，上部的内面110i适于与下部120的内面120i接触。上部110和下部120各自具有贯穿开口，分别为112和122。开口112和122各自具有8mm直径的圆形形状，并且彼此对齐，以允许空气或流体流过适配器100。下部120的开口被密封环124包围，该密封环被布置在下部120的面向上部110的面上，即，在下部120的内面120i上。当上部110与适配器100的下部120接触时，该密封环124确保气密密封。待测试的样本产品被定位在适配器100的上部110与下部120之间、位于它们各自的开口112和122之前，然后在下部120上闭合上部110。
可以理解的是，代替或除了围绕下部120中形成的开口、在内面120i上设置的密封环，密封环124可以围绕上部110中形成的开口112被布置在上部的内面上。
下部120的外面120o可以设置有密封环126，其可以例如有助于测量流经适配器100的流量，即流经待测产品的流量。
如果基材层2设置有粘合剂层和/或硅层(参见下文描述的实施例)，则在测量基材层2的透气性之前，例如通过使用丙酮(acetone)或乙酸乙酯(ethyl acetate)来移除这些层。
当根据欧洲法规NF EN ISO 9237进行测量时，按照该法规的建议参数，受测区域的面积为20cm2，压力为200Pa，则基材层2具有高于0且低于1200l.m-2.s-1，或低于1000l.m-2.s-1，或低于600l.m-2.s-1，或通常低于500l.m-2.s-1的透气性。申请人已确定8mm直径的受测区域和具有20cm2表面的受测区域所获得的结果之间存在线性关系，因此两种测试方法是等效的。
因此，所示的基材层2具有高于零但在有限范围内的透气性。虽然这不能完全防止空气通过基材层2，但在该范围内的透气性的值能够防止诸如涂层等材料的迁移，该涂层将被设置在基材层2的一侧上，以迁移通过基材层2到达基材层2的另一侧。
基材层2的透气性特性通过基材层2的结构获得，而无需添加诸如附加涂层的补充层。因此，这抑制了已知物品的缺点，这些已知物品包括设置在布置有紧固元件3的基材层2的面上的诸如聚丙烯涂层的涂层，以保护紧固元件3免受设置在基材层2的相对侧的涂层材料迁移的影响。因此，紧固带1可以防止涂层材料的迁移，同时仍具有高于零的透气性，而无需添加诸如聚丙烯涂层的补充层，添加补充层会降低紧固带1的柔性，并且实现起来成本高且复杂。
基材层2可以由包括直径小于0.02mm，或更具体地小于0.01mm，或更具体地小于0.005mm的纤维和/或细丝的非织造材料制成。
在示例实施例中，非织造层2可以包括至少一层熔喷和/或纺粘材料。然后，非织造层2可以选择性地包括至少一层被布置在至少两层纺粘材料之间的熔喷材料。通过使用作为外层的纺粘非织造层，我们可以获得比具有以熔喷层作为外层的非织造层更柔软的非织造层。通过使用作为外层的纺粘非织造层，我们可以获得在非织造物的两个面上具有改进了锚定能力(anchoring capacity)的非织造层，例如，用于紧固件的基部与作为非织造物的基材之间的更好的锚定。此外，随着熔喷材料层数的增加，产品的渗透性降低。
根据图2中所示的本发明的示例实施例，基材层可以具有：两层纺粘层，其中，两层纺粘层中的一层的纤维/细丝的直径尺寸可以介于1微米与20微米之间或例如介于12微米与19微米之间；以及熔喷层，其纤维/细丝的直径尺寸可以介于1微米与10微米之间或例如介于1微米与5微米之间。基材层还可以具有多(N)层纳米纤维层，其纤维/细丝的直径尺寸小于1微米，在某种情况下介于0.05微米与1微米之间(通常严格小于1微米)。
根据图2中所示的本公开的示例实施例，基材层可以选自以下列表：纺粘、纺熔、SMS、SMMS、SS、SSS、SSMMS、SSMMS、SSMMMS，或者纺粘(S)和熔喷(M)层的另一组合，或SMNMS，或者纺粘(S)和熔喷(M)和纳米纤维(N)的另一组合。
根据图2中所示的本公开的示例实施例，基材层可以是子层的组合，例如具有两个、三个、四个、五个、六个或七个子层(例如纺粘子层)，这些子层的不同之处在于纤维/细丝密度、和/或纤维/细丝直径、和/或子层厚度、和/或纤维/细丝原材料、和/或纤维/细丝种类(并排、偏心、芯/套(core/sheath))和/或纤维/细丝重量。具体地，基材层仅包括纺粘子层。
根据图2所示的本公开的示例实施例，基材层2的第二相对面2B(或更一般地，未设置有紧固元件3的基材层2的面)可以设置有硅酮涂层4，从而形成基材层2的释放涂层(release coating)。
在示例实施例中，基材层2的基重(basis weight)在5gsm到100gsm的范围内，基重为在基材层2上添加其他元件(诸如紧固元件3或可选的涂层或层)之前的基材层2的重量。
在示例实施例中，基材层2的渗透性与基材层的表面重量之间的乘积(product)小于1800g.l.m-4.s-1，特别是小于1500g.l.m-4.s-1，或例如小于800g.l.m-4.s-1，特别是小于400g.l.m-4.s-1，按照ISO 9237，在200Pa的压力下，对具有8mm直径的受测区域的样本的透气性进行测量。基材层的渗透性与基材层的重量之间的乘积通常也高于零。
因此，基材层2的透气性的降低值可以防止这种硅酮涂层4的硅酮迁移通过基材层2到达包括紧固元件3的基材层2的相对侧。
根据如图3所示的示例实施例，基材层2的第一外面2A可以设置有粘合剂层5，该粘合剂层随后被设置在基材层2的第一外面2A与紧固元件3之间，并确保紧固元件3结合到基材层2。
因此，在这样的实施例中，基材层2的透气性的降低值防止可选的硅酮涂层4的硅酮迁移通过基材层2到达位于基材层2的相对侧上的粘合剂层5。
在替代实施例中，紧固元件3可以通过直接层叠被结合到基材层2。在这样的实施例中，粘合剂层5(如果有)可以被设置在基材层2的区域上，这些区域不同于布置有紧固元件3的区域。
以下表1提供了根据ISO 9237而受测的样本的不同示例，并示出了根据本公开可以用于提供紧固带的基材的示例。
