Abstract
本发明涉及具有改善柔软性的薄页纸产品及其制备方法。具体地说,柔软性的改善是通过成型之前在薄页纸机的湿部将一种或多种柔软剂/去粘合剂掺入纤维配料中,然后在薄页纸幅干燥之后用一种或多种柔软剂/去粘合剂进行局部处理而实现的。结果是,所得到的薄页纸具有增加的松厚性和平滑的表面感觉,这两个性能均有利于改善柔软性特性。
Description
发明背景
在薄页纸的制造中，不断改善薄页纸的柔软度是人们一直为之努力的目标。通常，先前的各种努力一直致力于减少薄页纸结构内纤维之间的粘结，或者用改善表面手感的化学剂对薄页纸进行涂布。然而，柔软度是包括各种因素的薄页纸的感觉性能，这些因素包括松厚柔软度和表面平滑度。迄今为止，各种努力均致力于一个或另一个方面。因此，一直需要一种既能改善松厚柔软度又能改善表面柔软度的方法。
发明概要
业已发现，通过组合添加一种或多种柔软剂/去粘合剂(softener/debonder)(下面将定义)至制造薄页纸的配料中，然后再次添加一种或多种柔软剂/去粘合剂至干燥薄页纸的表面中，能改善薄页纸的柔软度。一开始向配料中添加柔软剂/去粘合剂给薄页纸提供了更好的松厚柔软度，而随后局部的施加赋予了更为平滑或光泽的表面感觉。这种组合得到了手感十分柔软的薄页纸产品。
更具体地说，本发明涉及柔软薄页纸的制备方法，该方法包括：(a)以干纤维重量计，形成包含约为0.01-约6％(重量)的一种或多种柔软剂/去粘合剂的造纸纤维的水悬浮液；(b)通过将该造纸纤维的水悬浮液沉积至成形网上而形成薄页纸幅；(c)对该纸幅进行脱水和干燥；以及(d)向该干燥的薄页纸幅局部施加约为0.01-约10％(重量)的一种或多种柔软剂/去粘合剂(以干纤维重量计)。局部施加至干燥纸幅中的柔软剂/去粘合剂可与形成薄页纸幅前添加至配料中的柔软剂/去粘合剂相同或者不同。

Z＝-CH2-CH2-CH2-O-(CH2)3-；和
n＝1-50。
最终的薄页纸产品具有增加的松厚性和平滑的表面感觉。实施例5
如实施例2所述制备双层层合的原纸，所不同的是，用含有50％有机聚二甲基硅氧烷(FTS-226)和50％季铵化合物(Mackernium KP)的含水组合物对这两层进行印刷。最终的薄页纸产品具有增加的松厚性和平滑的表面感觉。实施例6

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轴流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％。中间层构成了薄页纸剩下的30％重量，所述中间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5千克或0.5％的比例将湿强度剂(Parez 631NC)计量加入内层中。以总纤维重量计每吨纤维5.25千克(0.525％)的比例将柔软剂/去粘合剂(季咪唑啉，脂肪酸烷氧基化物和分子量为200-800的聚醚，商品名为DPSC 5299-8，得自Witco公司)加入到两个外层中。在薄页纸幅的形成，脱水和干燥之前，将各层的浓浆稀释至约0.12％的浓度。
干燥之后，仿照实施例4，用聚硅氧烷二季铵化合物(Abilquat3272)对该薄页纸进行涂布。与不进行涂布的薄页纸相比，最终的薄页纸具有更为平滑的表面感觉。
