Description

可冲刷掉的湿擦拭物或卫生用纸
技术领域
本发明涉及湿擦拭物(moist wipe)或卫生用纸(hygiene tissue)，其包括用润湿组合物浸渍的水力缠结的非织造材料。尤其是涉及湿的卫生纸和其它的擦拭物(wipe)或卫生用纸，目的是能在下水管道中冲刷掉。
背景技术
预润湿擦拭物或卫生用纸通常用于清洁人体的不同部位。特定应用的实例为婴儿护理、擦手、女性护理及用作卫生纸或与卫生纸配合使用。
由于从预润湿擦拭物制造时起到使用时止经常要过去很长的时间，因此在此期间预润湿擦拭物必须有足够的结构完整性，以保持其预期的擦拭功能。向擦拭物加入湿强剂可提供这类润湿完整性。然而，尤其是在用作卫生纸时，强烈要求擦拭物或手纸可以在下水管道中冲刷走，不会引起堵塞管道和滤网的问题。有很高湿强度的擦拭物或薄纸在传统的家庭厕所系统中冲刷时不会碎裂或分裂成小的纤维块，这可能会引起排水系统的堵塞。
例如根据美国专利US 3,554,788，以前知道使用含有水溶性组分的粘合剂，作为在水可分散的非织造材料中的粘结剂。据说该材料有良好的干强度，却很容易分散在水中，并且是可冲刷掉的。该非织造材料是在干燥条件下包装的，其所能保持的足够的结构完整性不会比湿擦拭物所要求的时间更长。
水力缠结的三层夹心结构制造的湿擦拭物通过美国专利US 6,110,848已为人所知，所述夹心结构包括合成纤维的外层和纤维素纤维的中间层。
目前市场上的大部分润湿的可冲刷的预润湿卫生纸是由于其尺寸小而可冲刷。它们可以沿排水和污水管移动，但不能轻易分散，因此可能会引起堵塞管道和滤网的问题。
US 2004/0112783公开了干的棉纸(tissue paper)和为此的贮片箱，其中棉纸在纵向和横向方向有规定的拉伸强度，从而防止其从箱中取出时被撕破。在干燥的条件下，纵向拉伸强度高于横向拉伸强度2.5～3.5倍。
JP-A-2006181764公开了使用水合纸张形成的具有多层结构的水可降解的擦拭物。该水可降解的擦拭物用含碱金属离子的金属离子的水性洗涤剂浸渍。它纵向的与横向的湿强度之比为1.0～3.5，并且横向的湿强度低于0.5N/25mm。
发明内容
本发明的目的是提供用来能在下水管道中冲刷掉的湿擦拭物或卫生用纸。本发明目的的解决是通过以下事实：湿擦拭物或卫生用纸，其包括用润湿的组合物浸渍的水力缠结的非织造材料，所述非织造材料含有以纤维重量计至少70％的纸浆纤维和余量的长度为至少6mm的人造纤维和/或天然纤维，并且所述湿擦拭物或卫生用纸有纵向长度和横向宽度，其中长度超过宽度至少25％，并且其中所述湿擦拭物或卫生用纸的纵向湿强度至少高于横向湿强度3倍，其中横向湿强度为50～200N/m。
纵向湿强度可以高于横向湿强度至少4倍，并且优选至少5倍。
纵向湿强度可以高于横向湿强度至多10倍。
所述人造纤维或天然纤维的纤维长度可以长达15mm。
湿擦拭物或卫生用纸以干重计算可含有不超过0.1重量％的湿强剂。
湿擦拭物或卫生用纸纵向的长度可以超过横向的宽度至少50％。
湿擦拭物或卫生用纸可以是湿的卫生纸。
湿擦拭物或卫生用纸的定量(basis weight)可以是40～100g/m2。
湿擦拭物或卫生用纸的横向湿强度可以是60～160N/m。
湿擦拭物或卫生用纸以纤维重量计可以含有至少5％的长度至少6mm的人造纤维和/或天然纤维。
具体实施方式
根据本发明的预润湿的擦拭物或卫生用纸包括用润湿组合物浸渍的水力缠结的非织造材料。润湿组合物可以含有主要比例的水和取决于应用目的的其它成分。用于湿擦拭物和卫生用纸的润湿组合物在本领域中为公知。
水力缠结法或水刺法是1970年代期间引入的形成非织造网的技术，例如参见CA 841938。该方法涉及形成纤维网，可以是干法成网或湿法成网，在成网后纤维通过非常细的水喷流在高压下缠结。几排水喷流导向活动的多孔支撑或穿孔鼓支撑的纤维网。在该方法中纤维相互缠结，为纤维网提供足够的粘合强度，无需使用化学粘结剂。然后干燥缠结的纤维网。用于所述材料的纤维可以是天然纤维，尤其是纤维素类纸浆纤维、短纤维(staple fiber)，以及纸浆纤维和短纤维的混合物。水刺材料可以以合理的成本高质量生产，并且它们有很高的吸水能力。
用于根据本发明的湿擦拭物或卫生用纸的纤维以纤维重量计为至少70％的纸浆纤维，并且其余为长度为至少6mm的人造纤维和/或天然纤维。优选湿擦拭物或卫生用纸以纤维重量计含有至少5％的长度为至少6mm的人造纤维和/或天然纤维。人造纤维可以是合成的，例如聚酯、聚酰胺、聚乙烯、聚丙烯、聚交酯以及其共聚物，或再生纤维素的短纤维，如粘胶丝、人造丝、莱赛尔(lyocell)纤维等。纤维长度为至少6mm的天然纤维可以是棉纤维、剑麻、大麻、苎麻、和亚麻等。
纤维素纸浆纤维可以选自任何类型的纸浆以及其共混物。优选地纸浆的特点为全天然的纤维素纤维，并且可以包括木质纤维和棉。优选纸浆纤维为软木造纸纸浆，虽然也可使用硬木纸浆和非木质纸浆，如大麻和剑麻。纸浆纤维的长度可以变化，从低于1mm的硬木纸浆和再循环纸浆到高达6mm的某些类型的软木纸浆。优选使用纸浆纤维，因为它们不贵、现成并且有吸收能力。
然而短的纸浆纤维在水力缠结期间互相缠绕和缠结的能力相当差，因此通常要与更长的纤维混合，以产生有足够强度的水力缠结的网。这些平均纤维长度为至少6mm的更长的纤维可以是如上所述的人造纤维和/或天然纤维。优选地所述更长纤维的纤维长度不超过15mm。更长的纤维的细度可以在0.3dtex～6dtex之间变化。
将纤维混合并形成纤维网。纤维网可以干法成网或湿法成网。在湿法成网方法中将纤维分散在液体中，通常为水，其方法类似于造纸方法中的，稀释的纤维分散体沉积在多孔支撑部件上，在此脱水以形成连续的网状材料。纤维分散体可以稀释成典型地用于传统造纸方法中的任何稠度。泡沫成形方法是湿法成网法的变例，将表面活性剂加入发泡的纤维分散体中，发泡的纤维分散体沉积在多孔的支撑上。在泡沫成形方法中可以实现非常均匀的纤维分布，并且还可以使用比传统的湿法成网方法中更长的纤维。
形成的纤维网然后经受几排喷嘴的水力缠结，高压水喷流从喷嘴冲向纤维网，而纤维网由多孔支撑件支撑。将纤维网在吸水箱(suction box)上排水。由此，水喷流完成纤维网的水力缠结，即纤维缠绕。水力缠结喷嘴中的压力可适当调节，以适应纤维材料、纤维网的克数等。来自水力缠结喷嘴的水通过吸水箱除去，并且泵送到水净化厂，然后循环回水力缠结工段。
对于水力缠结或如也称为水刺的进一步说明可参见例如CA 841938。
水力缠结可以发生在一个或几个步骤，并且可在网的一面或其两面上。所述网可以在随后的两个水力缠结步骤间转移到另外的多孔支撑上。
使缠结材料脱水，并且进入干燥阶段，以在成品材料卷起并转变之前干燥。可以通过向纤维网吹热空气、用红外干燥器或其它的非简易干燥技术进行干燥。
缠结的网被转变成适当尺寸的擦拭物或卫生用纸，其中擦拭物或卫生用纸应该具有网的纵向长度和网布的横向宽度，其中所述长度超过宽度至少25％。擦拭物或卫生用纸的形状可以是长方形或任何其它的可选形状，只要长度/宽度的关系如以上所述。如果长度和/或宽度沿着擦拭物或卫生用纸变化，所指的是纵向的最大长度和横向的最大宽度。
可冲刷掉的擦拭物或卫生用纸的合适尺寸为：长度9～25cm且宽度7cm～15cm。
擦拭物或卫生用纸的湿强度纵向比横向应该高至少3倍，优选至少4倍，并且进一步优选至少5倍。纵向的湿强度可以高于横向的至多10倍。
横向湿强度应该为50～200N/m。
湿强度根据测试方法SS-EN IS012625-5：2005用水测定。
不包括润湿组合物，以纤维材料的干重计算，擦拭物或卫生用纸的定量优选为40～100g/m2。
所述湿强度性能使得擦拭物或卫生用纸在通常用于擦拭的方向，即产品的长度方向强固。这可降低使用期间破裂和戳破的风险。宽度方向进一步相对较弱，这一方向通常在擦拭期间处于较低的应力，并可使擦拭物能在使用后在下水道中破碎和分散。
通过控制水力缠结的工艺，例如水力缠结喷嘴中的压力和/或通过该工艺的成网速度，可以实现相对较低的横向强度。因此通过降低水力缠结喷嘴的压力和/或提高工艺速度，水力缠结网的强度性能通常会降低，尤其是横向强度。由于纤维取向以及纵向强度受水力缠结工艺影响的程度不如横向强度，纵向强度总是会更高。还知道可以通过控制来自引入箱(inlet box)的纤维分散体相对于网线(wire)形成速度的喷射速度，在纤维网形成期间进行纵向方向的纤维取向。
擦拭物或卫生用纸可以进行起绉、压花或经其它纹理处理，以提高产品的柔软性。通常，处理网提高柔软性会倾向于降低网的湿强度。
擦拭物或卫生用纸用润湿组合物浸渍，所述润湿组合物含有取决于产品应用目的的成分。润湿组合物的主要比例通常为水。其它成分可以包括清洁剂、护肤剂、灭细菌剂、杀真菌剂、润肤剂、香精、防腐剂等，取决于应用目的。
根据本发明的擦拭物或卫生用纸的一个用途是作为湿的卫生纸。作为实例，湿卫生纸中的合适的润湿组合物可以是水基的，并且可以含有如以下的成分：丙二醇、苯氧基乙醇、可可葡糖苷(coco-glycoside)、聚氨基丙基二胍、脱氢乙酸、香精、可可氨基丙基甜菜碱、德国洋甘菊(chamomillarecutita)、红没药醇、柠檬酸、戊基肉桂醛(amylcinnamal)、香茅醇、己基肉桂醛(hexylcinnamaldehyd)、和丁基苯基甲基propional等。
擦拭物或卫生用纸可以不含或含非常少量的湿强剂。“少量”在此定义为以擦拭物或卫生用纸的干重计算，湿强度剂至多0.1重量％。多量的湿强度剂会使擦拭物的可冲刷性变差，并且使其更难以在下水管道中破碎和分散。
湿擦拭物或卫生用纸或者单独地包装在可由使用者撕开的密封包装中，或包装在含有许多擦拭物或棉纸的分装物中，可以通过分装物中的分装开口分配。
