    摘要： A cationic cellulosic fibre containing between 1 and 30 cationic groups and between 0.1 and 20 aldehyde groups per 100 anhydroglucose units is a suitable basis for producing paper and tissue products without the necessity of using non-biodegradable cationic polymers as wet strength additives. The cationic cellulosic fibre can be obtained by oxidation of the fibre to introduce aldehyde groups, followed by reaction of part of the aldehyde groups with a nitrogen-containing reagent such as betaine hydrazide hydrochloride. The fibre is advantageously combined with an anionic polymer such as monoaldehyde carboxyl-starch or with anionic cyclodextrin.

    摘要： Electrophotographic paper and a method for its production, according to which method a cellulose pulp is slushed, a filler is mixed with the slush, and the slush is formed in the paper machine into a web, which is dried. According to the invention, bivalent or trivalent cations in an amount of at least 0.1% of the dry weight of the pulp are attached to the acid groups of the cellulose pulp before the forming of the web. Thereby a paper web is obtained the surface charge of which is at least approximately 600 V when relative humidity is 40%. The surface charge of the paper according to the invention remains stable within a wide humidity range. For this reason, when the paper according to the invention is used, the need for drying the paper in the printing press is significantly reduced.

    摘要： The invention is a fibrous, cationic cellulose pulp product and the method for preparing it. A water suspension of cellulosic fiber is treated under alkaline conditions with a condensate of epichlorohydrin and dimethylamine. Up to 30 molar percent of the DMA may be replaced by a crosslinking agent such as ammonia or a lower aliphatic diamine. The process may be carried out at room or elevated temperatures. It is practical to add the condensate at one of the later alkaline stages of a bleaching process; e.g., an alkaline extraction or peroxide stage. This is most preferably done later than any chlorination or hypochlorite stages. The product shows greatly improved retention of acid and other anionic dyes. It also shows superior retention of some pigments and latices without the need for other cationic aids. In some cases a small amount of alum appears to have a synergistic retention effect with the cationic pulp product when used with titanium dioxide and certain anionic latices.

    摘要翻译： 本发明是纤维状阳离子纤维素纸浆制品及其制备方法。 在碱性条件下用表氯醇和二甲胺的缩合物处理纤维素纤维的水悬浮液。 高达30摩尔％的DMA可以由交联剂如氨或低级脂族二胺代替。 该方法可以在室温或高温下进行。 在漂白过程的后期碱性阶段添加冷凝物是实用的; 例如碱性提取或过氧化物阶段。 这最好比任何氯化或次氯酸盐阶段晚。 该产品显着改善了酸和其他阴离子染料的保留性。 它还显示出一些颜料和胶乳的优异保留性，而不需要其它阳离子助剂。 在一些情况下，当与二氧化钛和某些阴离子胶乳一起使用时，少量的明矾似乎与阳离子纸浆产品具有协同的保留效果。
