Abstract
在形成薄页纸幅之前，通过在薄页纸机湿部添加一种或多种造纸纤维的柔软剂/去粘合剂和聚硅氧烷二醇共聚物，可制得具有改善松厚性和柔软度的薄页纸产品。合适的柔软剂/去粘合剂包括：有机活性聚硅氧烷，季铵化合物，季铵化蛋白质化合物，磷脂，和聚硅氧烷季铵类。
Description
发明背景
在搽面纸和浴巾纸领域中，为了给消费者提供更好的产品，人们一直在进行各种各样的努力，以便改进薄页纸的各种性能。在这些性能中，一直想进行改善的是柔软度。
因此，需要增加薄页纸产品柔软度的新方法。
发明概要
业已发现，通过将聚硅氧烷二醇和一种或多种柔软剂/去粘合剂(softener/debonder)的混合物掺入到薄页纸中，可同时赋予该薄页纸以松厚性和优越的柔软度。在本发明中所使用的“柔软剂/去粘合剂”是选自季铵化合物类，季铵化蛋白质化合物类，磷脂类，聚硅氧烷季铵类和有机活性的聚硅氧烷类的化合物，所有这些物质均将在后面进行进一步描述。更具体地说，业已发现，其中存在有季柔软剂/去粘合剂，通过增加聚硅氧烷在纤维上的留着率，可增强聚硅氧烷二醇的有效性。
因此，一方面本发明涉及柔软的薄页纸，所述薄页纸含有：造纸纤维以及以纤维重量计为约0.01-约6％的、一种或多种柔软剂/去粘合剂的活性物质，和以纤维重量计为约0.0001-约3％的、聚硅氧烷二醇的活性物质；所述柔软剂/去粘合剂选自：季铵化合物类，季铵化蛋白质化合物类，磷脂类，聚硅氧烷季铵类和有机活性的聚硅氧烷类。更具体地说，以纤维重量计，柔软剂/去粘合剂的用量可为约0.1-约3％的活性物质；以纤维重量计，聚硅氧烷二醇的用量可为约0.005-约1％的活性物质。
另一方面，本发明涉及柔软薄页纸的制备方法，该方法包括：(a)将一种或多种柔软剂/去粘合剂和聚硅氧烷二醇或者单独地或者以复合的水混合物形式添加至造纸纤维的水悬浮液中，其中，柔软剂/去粘合剂的用量以纤维重量计为约0.01-约6％的活性物质，更具体地说为约0.1-约3％的活性物质；和聚硅氧烷二醇的用量以纤维重量计为约0.0001-约3％的活性物质，更具体地说为约0.005-约1％的活性物质；(b)将该造纸纤维的水悬浮液沉积在成形网上，形成一薄页纸幅；(c)对该纸幅进行脱水和干燥。所添加的聚硅氧烷二醇和柔软剂/去粘合剂的量主要取决于被纤维留着而不和水一起穿过该体系的聚硅氧烷二醇和柔软剂/去粘合剂的量，以及所述材料的成本。
合适的聚硅氧烷二醇包括但不局限于具有下面结构式的那些物质：
式中R＝C1-C6烷基；

除聚硅氧烷二醇以外，还可向薄页纸中添加其它的非离子表面活性剂。可使用的非离子表面活性剂系列的例子包括，烷基酚乙氧基化物类；脂族醇乙氧基化物类(脂族醇的烷基链可以是直链或支链的，伯或仲烷基)；脂肪酸乙氧基化物类(脂肪酸可以是饱和或不饱和的)；脂肪醇乙氧基化物类；环氧乙烷和环氧丙烷的嵌段共聚物类；环氧乙烷和由环氧丙烷与乙二胺反应得到的产物的缩合产物；环氧丙烷和由环氧乙烷与乙二胺反应得到的产物的缩合产物；包括水溶性氧化胺类的半极性非离子表面活性剂；包括烷基聚苷类的烷基多糖类；脂肪酸酰胺表面活性剂类。
另外除聚硅氧烷二醇和其它的非离子表面活性剂以外，还可有利地包括有多羟基化合物。有用的多羟基化合物的例子包括：甘油，和重均分子量为约200-4000，优选为约200-1000，最佳为约200-600的聚乙二醇和聚丙二醇，尤其优选的是重均分子量为约200-600的聚乙二醇。

实施例
实施例1
使用多层网前箱制备单层、未起皱、穿透空气干燥的薄页纸。两个外层包含以约34％的浓度和约184°F的温度通过输入功率为80kw的Maule轴式分散器的漂白的桉树阔叶木硫酸盐浆粕。两个外层占薄页纸纤维重量的70％。剩下的30％重量的薄页纸构成了内层，所述内层由北方针叶木硫酸盐浆粕组成。该薄页纸的总定量为33.9克/平方米风干薄页纸。对内层浆进行精制，以便在最终产品中得到足够的干强度。以每吨纤维5千克活性物质的量将湿强度剂，Parez 631NC(得自CytecIndustries，Inc.的乙醛酸酯化的聚丙烯酰胺)加入内层中。对包含4％重量的季铵化合物(甲基-1-油基酰氨基乙基-2-油基咪唑啉甲基硫酸盐)(Varisoft 3690，得自Witco公司，90％活性物质)和1％重量得自道康宁公司的聚硅氧烷二醇(Dow Corning 190)的柔软剂的水混合物进行预混，并添加至以浓浆(2％浓度)方式的外层中。在形成薄页纸幅之前，将各层的浓浆稀释至约0.12％的浓度。最终配料包含5.25千克Varisoft3690/吨(0.525％干重)和1.32千克Dow Corning 190/吨(0.132％干重)。与只利用季化合物而没有聚硅氧烷二醇制得的类似的薄页纸相比，最终的薄页纸具有更好的接触柔软度。
实施例2
