Description

可冲洗和可分散的干的化学粘合非织造物
                     技术领域
本发明涉及制备干的粘合可再分散非制造网的方法。
                     背景技术
产品的可处理性问题对非织造物工业有很大关系。不同类型的可处理性非织造物中有预湿的非织造物，其易于分散在大量的水或液体中，还有吸收性可处理非织造物，其能够用作抹布而且要求在接触液体后具有高水平的强度。
近年来，提出了大量的抹布和擦拭产品，声称它们在使用后能够被冲洗。大部分这些产品是基于尺寸可冲洗的；即，抹布或擦拭物较小足以通过马桶底部的开口并在理想条件下通过卫生管道和污水管道。这些产品通常基于在冲洗过程中不会破碎的水力缠结非织造网。这些产品在若干情形下能够危及污水或排水管道。如果大于推荐量的抹布被冲洗(例如被儿童冲洗)，这些抹布可能卡在弯管中，成为堵塞物，其妨碍水的流通并造成了阻塞。这些抹布还可能缠住有时伸入污水管道的树根造成堵塞和阻塞。非常需要这些非织造抹布或擦拭物分散使纤维网破碎成单独的纤维素纤维，这些纤维能够更容易地通过在污水和排水管道中碰到的障碍物。
对于可分散非织造物，该产品可以被制成干材料，如薄纸或抹布，当沉积在大量的水或水溶液中时，其将是真正可冲洗和可分散的。该薄纸或抹布必须在轻度搅动下解体在水中，而无需增加温度或添加化学制品。
水溶性或可再分散的聚合物粘合剂已用于制备非织造基材而且它们通常由聚(乙烯醇)(PVOH)、PVOH-稳定的乙酸乙烯酯或基于乙酸乙烯酯的聚合物例如乙酸乙烯酯-乙烯(VAE)乳液聚合物组成。处理的干非织造网需要具有足够的湿强度以使它们在使用中不会解体但将解体在过量的水中如马桶中的水。目前的许多商业非织造网不是不具有湿强度就是具有大的永久湿强度。前者不适于用在如女用卫生产品的产品中，这是因为它们会损伤破裂。后者不能在没有堵塞管道的危险下安全地丢弃在马桶中。
已提出几种方法，旨在使用过程中干的非织造产品的解体。一种方法采用向含水洗剂组合物添加硼酸或衍生物，将该含水洗剂组合物施加到非织造基材上以便保持非织造基质的完整性。以下专利阐明了该工艺的现有技术：
US 4,245,744公开了用基于含PVOH的乙酸乙烯酯的聚合物浸渍的非织造纤维片材，其中非织造片材保持与PVOH的沉淀剂或胶凝剂，如硼酸，的稀水溶液接触。
US 5,252,332公开了包含用与含硼酸离子和碳酸氢根离子的水溶液接触的PVOH或含PVOH的粘合剂浸渍的非织造纤维片材的封装小毛巾。
US 5,629,081公开了预湿、可分散和生物可降解的湿抹布，其包含与含PVOH的粘合剂接触的非织造纤维网。该粘合剂接触的纤维网还包含含水洗剂溶液，其包含基于洗剂重量0.1-0.9wt％的硼酸和5-8wt％的碱金属碳酸氢盐。
US 5,384,189公开了可水分解的非织造织物，其中纤维用水溶性粘合剂彼此粘合，该水溶性粘合剂包含不饱和羧酸/不饱和羧酸酯共聚物，其中来自于羧酸的1-60摩尔％的重复单元是盐的形式。该粘合剂溶于自来水但不溶于含有不小于0.5wt％的包含单价离子的中性无机盐的水溶液。
US 5,972,805公开了用于制备非织造网的水溶性聚合物粘合剂组合物，其包含25-90wt％的不饱和羧酸/不饱和羧酸酯/酯共聚物、10-75wt％的二价离子抑制剂和0-10wt％的增塑剂。该水溶性粘合剂组合物溶于具有小于约50ppm的二价离子浓度和小于约0.5wt％的单价离子浓度的含水环境。
US 5,256,417公开了可处理的并包含用粘合剂例如PVOH或含有PVOH作为保护胶体的含水聚合物乳液浸渍的非织造纤维片材的封装小毛巾。通过接触非水洗剂组合物将该非织造纤维片材保存在包装内的湿环境中，上述非水洗剂组合物是作为PVOH的非溶剂的液体有机化合物。
US 5,976,694、US 6,121,170和US 6,495,080公开了可冲洗的可处理产品。该可冲洗产品的特征是它对于它的预期使用具有充足的湿强度，但是一与大量的水接触就丧失了它的结构完整性。用于形成该可处理产品的组合物包含自至少一种水敏性聚合物以及至少一种选自聚交酯、用极性基如马来酸接枝的聚烯烃和其它脂族聚酯的聚合物的共混物。可分散性取决于水溶液中单价或多价离子的量。
WO 00/39378公开了含有热敏和离子灵敏粘合剂材料的水分散性非织造织物，其用于制造可冲洗个人护理产品。
添加剂如硼酸和单价或多价离子在工业中典型地称作触发剂(trigger)。这些触发剂与水溶性粘合剂相互作用以增加纤维网的湿抗张强度。这使纤维网用水溶性粘合剂和触发剂的组合粘合，以便在需要纤维网在使用条件下保持其完整性的应用中起作用，如湿抹布中。当纤维网置于过量水中(即马桶中)时，这些触发剂的浓度被稀释，破坏了粘合剂和触发剂之间的相互作用并引起了湿抗张强度的下降。当纤维网的湿抗张强度减小时，它能够在搅动下破碎并分离成较小的片，其能够更容易地通过排水和污水管道。
对于预湿产品，气流法纤维网能够用水溶性粘合剂制造，而且触发剂可以被添加到洗剂中产生相互作用。
在工业中需要改进的和经济的方法将触发剂引入到干非织造产品中。该方法将产生一种如下产品，该产品当变得潮湿或湿润时能保持它的完整性，但是能够完全分散在大量的如马桶中的水或含水液体中。
                     发明内容
本发明涉及将触发剂如硼酸、硼酸盐、硫酸钠或其它有机或无机盐引入到干的非织造网中的方法。在一个方法中，触发剂是干粉状的并在用水可再分散粘合剂处理纤维之前添加到非织造纤维中。这可以通过在具有含水粘合剂的单线(single line)中或具有含水粘合剂的可选择线(alternative lines)中混合干粉触发剂和纤维来完成。这一技术通常用于将超吸收粉末(SAP)定量给料到非织造织物中。用水可再分散粘合剂处理之后，加热处理过的非织造纤维网以粘合纤维并干燥纤维网。
添加触发剂的另一种方法是用触发剂水溶液喷淋干的粘合非织造网或将干的粘合非织造网浸泡在触发剂的水溶液中，然后干燥饱和的纤维网。
添加触发剂的另一种方法是将触发剂水溶液施加到纤维网上，接着将可再分散的含水粘合剂施加到该纤维网上，然后加热并干燥该纤维网。
使用一种将触发剂引入非织造网基材的上述方法得到了当在使用期间变得潮湿或湿润时具有良好的完整性，但是当经受大量的如马桶中的水或液体时将解体的干非织造产品。
对于可冲洗预湿抹布，触发剂被用于润湿抹布的洗剂携带。在本发明中，不需要为了将触发剂引入到干非织造网中而将洗剂施加到非织造网中。
                   具体实施方案
在用水可再分散粘合剂粘合纤维网之前或之后，可以将触发剂引入到非织造纤维网中。触发剂的例子是硼酸、四硼酸纳和其它硼酸盐、硫酸钠、柠檬酸钠和其它有机或无机盐。盐用作水粘合化合物而且可以添加到含水组合物中以参与防止水溶性聚合物粘合剂的溶解。水粘合材料和/或触发剂的量可以为含水固体的3wt％到约100wt％，优选5-95wt％，最优选20-90wt％，含水固体即除水之外的构成含水组合物的成分。水粘合化合物包括无机和有机酸的铵、单价和多价金属盐。适宜的金属包括碱金属如锂、钠和钾，和碱土金属如镁和钙。适宜的酸部分包括有机酸如碳酸、柠檬酸、乙酸和琥珀酸，和无机酸如磷酸、硫酸和盐酸。典型的盐包括氯化钠、硫酸钠、乙酸钠、柠檬酸钠、碳酸钠、碳酸氢钠、十二烷基硫酸钠、月桂基醚(laureth)磺基丁二酸二钠、月桂基醚硫酸钠、壬基苯酚乙氧基化物硫酸钠、磷酸二钠、碳酸钠、和它们的铵或钾对应物。
如果在用粘合剂粘合纤维网之后将触发剂施加到纤维网，用触发剂水溶液浸泡或喷淋该粘合的纤维网。然后干燥该纤维网，保留嵌入在纤维网中的触发剂。
如果在用粘合剂粘合纤维网之前施加触发剂，当浆粕离开锤磨机时或在浆粕移出锤磨机之后的一些地方，通过将其以干燥形式添加到浆粕中引入触发剂。例如，通过将其从移动毛毡上方滴加到浆粕上可以将触发剂添加到一个、一些或所有流浆箱中的浆粕中。通过在两个或多个流浆箱之间的自由下落或任何目前使用的或已知的将超吸收粉末添加到非织造网的方法也可以添加触发剂。如果作为干触发剂添加，它应当是粉末或颗粒形式。通常，粒径应当较小足以使颗粒落入纤维间的空间并且足以使表面积和与粘合剂的相互作用最大化。粒径，即平均颗粒直径，可以为大约50到2000微米；典型地大约200到750微米。
添加到非织造网的干触发剂量可以为最终纤维网重量的1-50％。该量取决于所用触发剂的类型和对最终纤维网的应用。触发剂典型的量为最终纤维网的5-40wt％和10-30wt％。然而该范围可以为1-50wt％的任何组合。
在施加粘合剂之前添加触发剂的另一个方法是用触发剂的水溶液喷淋或浸透未粘合纤维网，然后施加含水粘合剂。根据处理过的纤维网的性能目标，可以超过一次的进行该工序以增加触发剂和/或粘合剂的水平。
用于可分散非织造产品的水可再分散乳胶聚合物粘合剂通常是非交联的，即，它不包含交联到聚合物变成相对不可再分散程度的聚合的NMA单元。外来交联剂的添加还不是合乎需要的。这些网络结构或者可以表面活性剂保护或者用保护胶体如PVOH或HEC稳定。最理想的是，水可再分散乳胶聚合物包含在用水乳液聚合制备中作为稳定系统组分的PVOH保护胶体。PVOH稳定的乙酸乙烯酯和基于乙酸乙烯酯的聚合物，例如VAE聚合物乳液由于它们容易的水可分散性而成为优选的。PVOH或表面活性剂保护的丙烯酸类聚合物、丙烯酸系共聚物和苯乙烯丁二烯共聚物也适于该应用。
用于非织造网的水可分散粘合剂还可以是如上所述的乳胶和PVOH的共混物。这些乳胶/PVOH共混物还可以包含添加剂如聚(丙烯酸)、淀粉、和各种润湿剂或具有羟基或羧基官能团的添加剂。配方的PVOH部分可以有70-100％的任何水解。PVOH共聚物，如磺化物料或聚(乙烯醇/乙烯胺)，或不同分子量和/或水解的PVOH的共混物也可以用在乳胶共混物中。此外，粘合剂可以是公开在US6,815,502和US 6,599,848，和其所引用的参考文献中的离子灵敏水分散性聚合物系列的成员。商业粘合剂的例子是VINAC911和VINAC912乙酸乙烯酯-聚(乙烯醇)聚合物乳液。
可以使用的水可再分散性乳胶聚合物粘合剂包括但不限于基于乙酸乙烯酯的聚合物，例如，用PVOH稳定并具有-45℃到50℃的Tg的乙酸乙烯酯均聚物或VAE聚合物。还可以有低水平的其它单体聚合到VAE聚合物主链上。这些单体可以包括(甲基)丙烯酸、巴豆酸、烷基为C1-C12的直链或支链的(甲基)丙烯酸烷基酯、烷基为C1-C12的直链或支链的二或单烷基马来酸酯、(甲基)丙烯酰胺、烷基为C1-C12的直链或支链的二或单烷基取代的(甲基)丙烯酰胺、烷基为C1-C12的直链或支链的链烷酸乙烯酯、丙烯、氯乙烯和乙烯基乙烯碳酸酯。
用作共混物成分的PVOH可以具有75-96摩尔％的水解度，优选87-89摩尔％。它还可以具有大于96摩尔％的水解度。优选使用的PVOH具有高分子量；600到2500或更高的聚合度(DPn)。增加水解度的PVOH易于产生再分散更慢的纤维网。该性质不会阻碍该分散体作为适宜的粘合剂，但是它们在一些应用中是不太理想的。PVOH产品从Celanese Chemical Company商业可得而且具有Celvol注册商标。
术语聚(丙烯酸)是指在聚合物主链中具有主要部分(例如，至少50％)和优选至少90％的聚合丙烯酸单元的聚合物。通常聚(丙烯酸)由聚(丙烯酰胺)的水解形成并因此残留的丙烯酰胺能够存在于聚合物中。该聚合物还可以具有任何分子量，但聚(丙烯酸)的优选数均分子量范围是100,000到500,000道尔顿。商业上适宜的聚(丙烯酸)的例子包括从Rohm & Haas可得的Acumer1540和Acumer 1510、从Cytec Industries，Inc.可得的CyanamerA-15、Cyanamer A-100L、Cyanamer P-21、CyanamerA-370、从Alco Chemical可得的Alcosperse 124、Alcosperse 404、Alcosperse 406、Alcosperse 459、Alcosperse 602A和Alcosperse 747和从Aldrich Chemical Company可得的几种等级的聚(丙烯酸)。
将该共混物以至少足以将纤维粘合在一起形成自持纤维网的量施加到纤维网。折干计算，在非织造网形成中，以通常大约5-50wt％，优选15-30wt％的量将该共混物施加到起始纤维网。以含水形式施加共混物后，将浸渍的纤维网加热到足够粘合和干燥纤维网的温度。用于干燥和粘合的温度范围可以为190到350(88到177℃)；典型地200到275(93到135℃)。然后，通过将纤维网浸泡在触发剂水溶液中或用触发剂水溶液喷淋纤维网可以将触发剂施加到粘合的纤维网。然后干燥该纤维网以形成干的可再分散非织造网。
通过喷淋、起泡沫、饱和浸轧或本领域已知的其它方法将粘合剂施加到纤维网。存在在最终纤维网上的粘合剂量可以为最终纤维网重量的5％到30％。
可分散非织造网由非织造纤维材料组成。纤维材料主要由纤维素木浆纤维组成，典型地具有添加量的织物纤维以增强湿和干强度。典型地，木浆纤维占非织造基材的大约75-100wt％和织物纤维占非织造基材的大约0-25wt％。优选的织物纤维包括粘胶纤维、棉、羊毛、乙酸纤维或天丝纤维(tencel fiber)。
木浆(单独或与天然或合成纤维混合)可以用干法成网工艺(气流、梳理、无规(rando))或湿法成网工艺加工以生产非织造网。由于与湿法成网非织造物相比，在最终产品中最少的纤维氢键键合，因此由气流成网工艺生产的非织造网是优选的。气流成网工艺少量地或没有赋予纤维网固有的完整性，该纤维网的完整性必须用搅动来克服以达到纤维网的完全解体。
在形成可分散非织造网的一个方法中，首先用水溶性或水可再分散粘合剂涂覆或浸渍该纤维网。这可以通过(1)将纤维网或运行长度的纤维网浸渍在水可再分散乳胶聚合物粘合剂的含水组合物中，尤其是用作为保护胶体的PVOH稳定的含水聚合物乳液中或(2)通过喷淋、浸轧、辊或本领域已知的其它施加类型将水溶性或可再分散聚合物粘合剂施加到非织造纤维网表面上实施。
形成干的可分散非织造网的另一个方法是当纤维网或浆粕离开锤磨机时或在从锤磨机移出纤维网或浆粕后的一些地方将触发剂以干粉形式施加到非织造网纤维。与将超吸收粉末(SAP)添加到气流成网纤维网的方法相似，粉末状的触发剂可以在纤维网形成过程中添加。例如，在纤维网形成过程中，干触发剂可以通过SAP定量给料法添加到在流浆箱中的纤维混合料上。还可以将其添加到漏斗中并通过流浆箱后面或之间的振荡筛网“喷洒”到纤维网上。后面的方法通常用于将粉末粘合剂施加到非织造网。当通过本领域已知的任何其它方法用移动带输送纤维网时，该触发剂还可以被滴加到纤维网上。干粉状触发剂的施用能使触发剂颗粒均匀地分散到纤维网中并最大化触发剂和粘合剂间的相互作用。然后用上述方法将水可分散粘合剂施加到含有触发剂的纤维网。然后粘合并干燥该纤维网纤维。
用于形成干的可分散非织造网的第三个方法是将触发剂水溶液施加到非织造纤维网，如上所述，然后将可再分散粘合剂的水分散体施加到非织造纤维网，如上所述。然后加热以粘合纤维并干燥纤维网。
以下实施例用于阐明本发明的各种实施方案但并不限制其范围。
                      实施例
下面的表1说明了非织造网的性能，该非织造网用可分散的粘合剂粘合，然后用两种盐溶液浸透。用于粘合纤维网，然后用盐或硼酸溶液浸透纤维网的工序如下：用300％纤维网重量的触发剂水溶液处理用水溶性粘合剂粘合的纤维网。盐溶液的浓度根据所需的添加量在5-15％变化。硼酸浓度为4.4％。所用的粘合剂是VINAC 911聚(乙酸乙烯酯)和含有大约80wt％乙酸乙烯酯和大约20wt％乙烯并具有约0℃Tg的VAE聚合物乳液。该粘合剂还包含聚(乙烯醇)作为稳定剂。
张力数据以每英寸负载克数为单位(g/in)。测试方法是TAPPIT494。
使用上述Intron测试方法获得洗净后(lotionized)抗张强度。在测试之前和以300％的纤维网重量粘合之后，用含有10％硫酸钠或4.4％硼酸的洗剂洗涤样品。
通过用1.6加仑水/次冲洗冲洗在美国标准马桶中的测试样品评估可冲洗性。将被评估的样品置于马桶15秒以使样品被马桶水均匀润湿。然后将该样品冲下马桶，其通过在马桶出口的90°角管子并收集在网筛上。用纤维网完整性作为要素主观评估可分散性以确定样品是否被分散。如果样品仍为整体，它将被再次冲洗并重新评估。如果该样品在5次冲洗后仍为整体，停止测试并确定该样品是不可冲洗的。

上述表中的样品1-4代表用VAE或聚(乙酸乙烯酯)聚合物乳液粘合剂粘合的气流成网纤维网。对于两种粘合剂，纤维网基重为90和135克每平方米(gsm)。如由数据所见，每种粘合剂都向非织造网提供了高度的干抗张强度。然而当测量湿抗张强度时，丧失了超过95％的抗张强度。例如，如果这些纤维网被洗成湿抹布，通过向洗剂添加硼酸或硫酸钠，湿强度提高了5-10倍。当冲洗这些洗后的抹布时，它们在2-4次冲洗中完全分散。样品5-12说明了通过将水溶性粘合剂和触发剂的组合施加到纤维网，然后干燥并粘合该纤维网制备的干纤维网的性能。纤维网的重量为90和135gsm。触发剂是硫酸钠和硼酸。数据显示这些粘合剂与没有触发剂的粘合剂相比，干抗张强度不相上下。然而在纤维网中具有触发剂(样品5-12)的纤维网比不具有触发剂(样品1-4)的增加了3-10倍的湿抗张强度。水溶性粘合剂加触发剂系统的湿抗张强度与样品1-4中粘合剂的洗后抗张强度具有可比性。这些产品在3-5次冲洗中分散。
下面的表2说明了如下制备的纤维网的性能：将粘合剂以10％的添加量施加到55gsm纤维网并干燥。评估的粘合剂是表1中的VINAC 911聚(乙酸乙烯酯)和VAE聚合物乳液，以及70/30的AIRFLEX 400乙酸乙烯酯聚合物乳液粘合剂和CELVOL523聚(乙烯醇)的干混物。将Acumer 1540聚(丙烯酸)添加到VINAC 911聚(乙酸乙烯酯)以确定聚(丙烯酸)对抗张强度的影响。在不含触发剂时，评估每个纤维网的干抗张强度和湿抗张强度。然后以每个样品纤维网重量的300％、400％和600％的水平添加触发剂作为洗剂并干燥以便将干触发剂引入到每个纤维中。施加的触发剂溶液是7.5％Na2SO4和4.4％硼酸。评估用水溶性粘合剂和触发剂的组合粘合的纤维网的可冲洗性和湿抗张强度。数据显示向每个粘合剂添加触发剂导致纤维网的湿抗张强度2到5倍的增加。如在少于5次的冲洗中完全分散所示，确定所有纤维网是可冲洗和可分散的。聚(丙烯酸)增加了VINAC 911和AIRFLEX 400-CELVOL 523系统的湿抗张强度。然而，基于该结果，利用聚(丙烯酸)达到所需的性能水平不是必须的。
