Abstract

本发明包括由在薄页纸外层中存在的去粘合剂/柔软剂以及在“封闭的”凹槽的条件下的起皱所得到的柔软、松厚的薄页纸产品。去粘合剂/柔软剂属于包括若干种咪唑啉季铵化合物的有机化学剂类。这些化学剂与绝大多数化学剂不一样,它们不会对薄页纸机的干燥表面的粘附力产生不利的影响。因此,它们可添加至与烘缸表面接触的薄页纸的外层中并改善皱纹。然后可使用封闭的凹槽从干燥表面上起皱并剥下该薄页纸,所述的凹槽角小于80度。封闭的凹槽起皱通常将产生更厚的、密度更小的但带有粗糙皱纹的薄页纸。可以预期,封闭的凹槽起皱以及在烘缸一侧的层中存在的大多数去粘合剂还将产生粗糙的皱纹结构。然而,本发明去粘合剂的性能和粘合剂的性能相互作用和封闭的凹槽起皱条件产生了松厚的薄页纸,该薄页纸具有足够细小的皱纹结构,这将使之具有很高的整体柔软度。

Description

利用封闭的起皱凹槽对包含柔软剂的薄页纸幅的起皱方法
发明背景
在工业实践中,在搽面纸和浴巾纸中使用去粘合剂/柔软剂是常见的。业已发现,向薄页纸机的湿部添加所述的化学剂将降低对干燥表面的粘附力。Soerens等人在US4,795,530中指出,在干燥和起皱之前,季铵类对通常在干燥和起皱过程之前用来达到适宜粘着力的粘合剂/去粘合剂的组合效应具有干扰作用。Oriaran等人在US5,399,241中指出,同样是这些化学剂,因不断在白水体系中循环而造成种种运行问题。上述两篇专利均指出,在纸幅成形并部分干燥之后将所述的化学剂喷涂至纸页上是避免上述这些问题的一种方法。我们的经验是,柔软剂通过干扰纤维与纤维间的结合而起柔软作用。另外,我们还有这样的经验,与Soerens和Oriaran所述的一样,绝大多数柔软剂确实能降低对烘缸的粘附力。降低的粘附力将导致纸页不太有效的破裂(break-up)和更为粗糙的起皱。这种表现更为粗糙的皱纹的纸页破裂的降低,将使薄页纸的柔软性总体上变差。这与添加柔软剂的目的是相矛盾的。
另外已证明,细皱纹且柔软的薄页纸是由80-90度的起皱凹槽角所产生的。US4,300,981(Carstens)在其实施例中表明了所述的凹槽角。小于80度的角度被认为是“封闭的(closed)”,并且如果不增加粘附力的话,据知将降低纸页的破裂。这同样也将产生粗糙的皱纹。
发明概要
业已发现,如果使用适当的柔软剂,采用封闭的起皱凹槽能生产出特别柔软的薄页纸。更具体地说,本发明允许在湿部添加特定的柔软剂,所述的柔软剂不会对薄页纸与涂有起皱粘结剂的干燥表面之间的粘附力产生不利的作用。由于在本发明中所使用的柔软剂的化学性质所致,可获得低密度和表面平滑度相结合的起皱薄页纸。低密度是由于封闭的凹槽起皱所致的,而表面平滑度是由对干燥表面的充分粘附力所产生的。
因此,一方面,本发明涉及干燥薄页纸幅的起皱方法,该方法包括:(a)将起皱粘结剂喷涂至旋转的起皱烘缸(扬克式烘缸)的表面上,所述起皱粘结剂包含含水聚酰胺树脂和阳离子低聚物如季铵化的聚酰氨基胺的混合物;(b)将薄页纸幅粘附至起皱烘缸的表面上,所述薄页纸幅含有具有下述结构式的咪唑啉季铵化合物:
Figure A9619686500051
式中x=甲基硫酸根或其它相容的阴离子;和
R=脂族、直链、饱和或不饱和的C8-C22;和
(c)通过与刮刀接触从起皱烘缸上取下薄页纸幅,所述刮刀被调整成紧抵起皱烘缸表面且与纸幅呈一起皱凹槽角,该角度约为78度或更小,更准确地说约为70-78度,再准确地说约为75-78度,在与刮刀相接触之前,所述薄页纸的含水量约为2.5%(重量)或更少。
另一方面,本发明涉及通过上述方法制得的薄页纸。
用于本发明目的的起皱粘结剂包含含水聚酰胺树脂与阳离子低聚物如季铵化的聚酰氨基胺的混合物。在起皱粘结剂配方中,聚酰胺树脂的用量约为10-约80%(干重),更特别的是约为20-约40%(干重)。在起皱粘结剂配方中,阳离子低聚物的用量约为5-约50%(干重),更特别是约为10-约30%(干重)。任选地,起皱粘结剂还可以包含聚乙烯醇,其合适的用量约为20-约80%(干重),更特别的是约为40-约60%(干重)。
合适的含水聚酰胺树脂是,如在US4,528,316(1985年7月9日授于Soerens,题目为“包含聚乙烯醇和阳离子聚酰胺树脂的起皱粘结剂”)中描述的热固性阳离子聚酰胺树脂,在此引入该文献作为参考。所述起皱粘结剂的聚酰胺树脂组分包含,由表卤醇,优选表氯醇,与含有由聚亚烷基聚胺和含约3-约10个碳原子的、饱和族脂二元羧酸衍生得到的仲胺基的水溶性聚酰胺的水溶性聚合反应产物。所述水溶性聚酰胺反应剂包含如下式的重复基团:
            -NH(CnH2nHN)x--CORCO--
式中n和x分别为2或更大,R是二元羧酸的二价烃基。所得到的阳离子聚酰胺树脂的主要特性在于,在起皱粘结剂中它们与聚乙烯醇是相兼容的;即它们不会在含水聚乙烯醇的存在下发生相分离。
在US2,926,116(1960年2月23日授于Gerald I.Keim)和US3,058,873(1962年10月16日授于Gerald I.Keim)中更详细地描述了用于本发明的聚酰胺树脂组分的制备方法,在此引入这两篇文献作为参考。尽管上述两篇专利均只指出了使用表氯醇作为反应剂与聚酰胺反应,但是,在适当的pH条件下,当与聚酰胺的仲胺基反应时,既然所有的表卤醇均能导致生成阳离子形式的聚酰胺树脂,因此,据信所有的表卤醇均能用于本发明的目的。
合适的、市售含水聚酰胺树脂包括,Kymene 557 LX(Hercules公司),Quacoat A252(Quaker Chemical),Unisoft 803(HoughtonInternational),Crepeplus 97(Hercules公司),和Cascamid(Borden)。
合适的、市售季铵化聚酰氨基胺包括,Quaker 2008M(QuakerChemical)。
虽然可在起皱刮刀之前任一位置将咪唑啉季铵化合物添加至薄页纸制造过程中,但优选在湿部添加,最优选在形成纸幅之前添加至造纸纤维水悬浮液的浓度约为2%或更大的浓浆中。可将咪唑啉季铵化合物添加至混合(不分层的)薄页纸或分层的薄页纸的造纸纤维悬浮液中。如果是分层的薄页纸,优选将咪唑啉季铵化合物添加至最终将接触起皱烘缸表面的该层的配料中。在大多数场合,该层也是与消费者接触的、最终薄页纸产品的面朝外的层。
在薄页纸幅中咪唑啉季铵化合物的用量可以是任意的,更具体地说,以最终产品中纤维的干重为基准,其用量约为0.05-约0.5%干重。其用量越少,在提供足够柔软性方面的效果就越小。其用量越多,在经济上就越没有吸引力。
合适的咪唑啉季铵化合物包括,Varisoft 3690(由Witco公司供应)和DPSC 5299-8(Witco公司),该化合物是与脂肪酸烷氧基化物和分子量为200-300的聚醚混合的季咪唑啉。
除了咪唑啉季铵化合物以外,还可将非离子表面活性剂在薄页纸抄造过程的湿部添加至薄页纸中,以进一步增加最终产品的柔软性。可使用的非离子表面活性剂类的例子包括,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,伯烷基或仲烷基);脂肪酸烷氧基化物类(脂肪酸可以是饱和的或不饱和的);脂肪醇烷氧基化物类;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类;包括烷基聚苷类的烷基多糖;和脂肪酸酰胺表面活性剂类。特别有用的非离子表面活性剂是具有下面结构式的聚硅氧烷二醇类:
Figure A9619686500071
式中R=C1-C8烷基;
R1=乙酸酯或羟基;
x=1-1000;
y=1-50;
m=1-30;和
n=1-30。
在湿部添加的聚硅氧烷二醇的用量可以是任何能增加薄页纸柔软度的有效量,更具体地说,以最终薄页纸中纤维的量为基准,约为0.0005-约3%干重,更优选约为0.005-约1%(干重)。
配合聚硅氧烷二醇和其它非离子表面活性剂,另外还可有利地包括多羟基化合物。有用的多羟基化合物的例子包括甘油和重均分子量约为200-约4000,优选约为200-约1000,最优选约为200-约600的聚乙二醇和聚丙二醇。尤其优选的是重均分子量约为200-约600的聚乙二醇。
在与刮刀接触之前,干燥薄页纸幅的含水量为约2.5%或更少,更具体地约为2.0%或更少,更优选地约为2.0-2.5%。准备根据本发明的起皱方法进行起皱的薄页纸幅可以是温压或穿透空气干燥的薄页纸幅。在这两种情况下,起皱烘缸优选是扬克式烘缸,在起皱之前,该烘缸将纸幅的含水量最终干燥至所希望的量。
在本发明的范围内也可以使用湿强度和干强度添加剂。合适的干强度剂包括但并不限于,聚丙烯酰胺树脂和羧甲基纤维素。合适的湿强度添加剂包括,暂时和永久的湿强度添加剂。合适的湿强度添加剂包括但并不限于,脲-甲醛树脂,蜜胺-甲醛树脂,环氧树脂,聚胺-聚酰胺-表氯醇树脂,乙二醛化(glyoxalated)的聚丙烯酰胺树脂,聚乙烯亚胺(polyethylent imene)树脂,双醛淀粉,阳离子醛淀粉,黄原酸纤维素,合成胶乳,乙二醛,丙烯酸乳液,和两性淀粉硅氧烷。

附图详述
图1是说明多层结构成形程序的多层结构成形过程的简图。该图示出了包含网前箱分层垫板2的双层网前箱1,所述垫板将第一浆层(较低或底层)与第二浆层(较上或顶层)分开。两个浆层各自由造纸纤维的稀释水悬浮液组成,其纤维浓度可以不同。所述浆层的浓度一般约为0.04-1%。由辊4和5适当支撑并驱动的、无端运行的成形网3接受从网前箱中送出的层状纸浆并将纤维截留在该网上,与此同时,使部分水份如箭头6所示排出。实际上,水份是通过重力,离心力,和真空抽吸力排除的,取决于成形构形。如图所示,第一浆层是第一个与成形网接触的浆层。第二浆层(以及如果使用多于一个垫板的网前箱的话,任何后续的浆层)是第二个形成的层,并且形成在第一层的上面。如图所示,第二浆层从不与成形网接触。因此,为了让水分通过成形网从纸幅中除去,第二层和任何后续的层中的水份必须穿过第一层。由于所有附加的水份均沉积在第一浆层上面,因此,这种情形也许被认为对第一层的形成是破坏性的,但业已发现,将第二浆层和后续的浆层稀释至低于第一浆层的浓度,对第二浆层和后续的浆层的成形,提供了实质性的改进,同时对第一层的成形也不会产生有害的影响。柔软剂通常是在浆料稀释前添加至浓浆中。添加柔软剂的浆层通常是与干燥表面接触的浆层。
图2是传统薄页纸抄造过程的流程简图。所示出的具体成形方式通常被称之为新月形成形器。图中示出了多层网前箱21,成形网22,成形辊23,造纸毛毯24,压辊25,扬克式烘缸26,和起皱刮刀27。另外在该示意图中还画出但未标出数字代号的、限定成形网运行路径用的各种惰轮或张紧辊,它们在实践中可以有所不同。如图所示,多层网前箱21连续地将层状浆射流沉积在成形网22和毛毯24之间,所述毛毯部分地缠绕在成形辊23上。随着新形成的纸幅不断通过成形辊的圆弧部分,水分借助离心力通过成形网从浆料的水悬浮中除去。当成形网和毛毯分开时,湿纸幅留在毛毯上并传送至扬克式烘缸26上。
在扬克式烘缸上,将水溶液形式的起皱化学剂连续地施加至起皱后残留的粘结剂的表面上。所述溶液通过任何方便的手段进行施加,优选使用将起皱粘结剂溶液均匀喷至烘缸表面的喷雾吊杆。施加位置在紧随起皱刮刀27之后,这样能使新鲜的粘结剂膜的分布和干燥有足够的时间。
借助每平方英寸约200磅(psi)压力的压辊,将湿纸幅送至烘缸的表面上。在到达压辊处,湿纸幅的名义浓度约为10%(约为8-20%之间)。在压榨或脱水步骤之后,纸幅的浓度约为30%或更大。然后将足够的扬克式蒸汽能量和烘缸罩干燥能力施加至该纸幅上,以达到最终约3%或更低,优选2.5%或更低的含水量。恰好在起皱刮刀之前的纸页或纸幅的温度优选约235°F,该温度是通过辐射系数约0.95的红外温度传感器测量的。
图3是说明起皱几何构形的起皱操作的简图。起皱凹槽,或凹槽角是由扬克式烘缸在接触刮刀处的切线与冲击低幅的那一刮刀表面之间的夹角形成的。该起皱凹槽角由双箭头示出,并且通常为80-90度。角度越小,对传输至薄页纸幅/粘结剂夹层上的能量就越大。然而,除非有足够的粘附力,否则增加的能量将使纸幅/粘结剂界面处出问题,将导致纸页折叠(表现为粗糙起皱),而不是能得到更低密度的、因而是更为柔软的纸页的压缩脱粘合。令人意想不到的是,由本发明得到的足够的粘附力使得由封闭的凹槽起皱产生的增加的能量造成粘结剂层本身破碎。这使得纸页能进行压缩脱粘合,得到更低密度,更柔软的纸页。
由本发明所产生的皱纹不象常见的利用封闭凹槽起皱得到的皱纹那样粗糙。然而,这种皱纹也不象如通过表面外形仪测量的、在现有技术中描述的那样细。事实上,本发明的皱纹结构是粗糙和细致结构的组合。当对本发明产品进行观察时,所看到的是,叠置在下层粗糙皱纹结构上的细致皱纹结构。因此,该细致的结构证实了纸页有效的破裂,而下层粗糙的结构增强了该薄页纸的质感。通过现有技术的表面外形仪对本发明产品进行测量,将把本发明的产品排除在细小皱纹的范围之外,并且预计它将不是柔软薄页纸。
图4示出了光学表面皱纹测量的结果,该图表明了该结果与表面外形有关,并进一步证实了本发明实施例(下文将描述)与如在将述Carstens的专利中描述的薄页纸之间的区别。该光学表面皱纹测试提供了皱纹折痕高度的数值以及两皱纹谷之间的距离。该测试所得到的数据是平均皱纹高度和皱纹谷之间的平均距离。所得数据还示出了不同大小范围数值的分布。在图4中示出的峰高度大于68.29微米总数。令人惊奇的是,通过消费者视觉和手感分析表明,赞成实施例1的薄页纸更柔软的人与赞成先有技术2的薄页纸更柔软的人数之比为63%∶37%,与现有技术2的薄页纸相比,实施例1的薄页纸是优选的。在95%或更高置信度下这种差别是显著的。显然,细小皱纹并不是柔软薄页纸的先决条件。
图5是如下所述的用来测量皱纹结构的装置的简图。其中示出了以与目标平面成30度角射出光线的平行光源(幻灯放映机)。将制得的薄页纸试样平放在试验台上,其中皱纹图案相对于光源以90度对准,结果产生了如通过虚线表示的皱折投射出的阴影。通过50mm透镜的Quantimet照相机对反射光进行观察并分析。
为了用图5所示的装置测定光学表面皱纹,通过用SCOTCH带在四个角处粘附薄页纸,并在柔和的张力下拉伸薄页纸,而将无皱纹的薄页纸试样固定在10×12英寸的玻璃板上。单层薄页纸用作浴巾纸;双层薄页纸(多层)用作搽面纸。使用高质量的毛刷并只在一个方向刷,对5×5英寸的薄页纸涂覆PENTEL改正液和异丙醇2/3∶1/3的混合物。足够的干燥时间为20分钟。
在50mmEI-Nikkor透镜的光轴下,将带有涂布薄页纸的玻璃板置于Cambridge Quantimet 900图像分析系统的automacrostage(DCI12×12英寸)上。以与幻灯放映机成30度角照射试样,以形成阴影。运行软件子程序“OCREP5”(内容见下面所列),以便进行分析。首先进行精确的黑点校正和系统校准。通过在对15个一厘米的皱折图进行分析以后得到两份柱状图表的打印输出。第一个柱状图表测量峰的高度。第二个柱状图表测量谷的距离。
