生产皱纸的方法
摘要：
本发明涉及通过借助粘合剂将纸幅粘合到起皱圆筒上制备皱纸的方法。所述粘合剂包括：(i)摩尔质量Mw为50,000-2,000,000的聚乙烯亚胺，(ii)由摩尔质量Mw为500-1,000,000的聚乙烯亚胺与至少一种C14-C22烷基双烯酮、一元羧酸、一元羧酸的酯或一元羧酸的酰氯形成的反应产物，和/或(iii)由摩尔质量Mw为300-1,000,000的聚亚烷基多胺与至少一种双氯醇醚或摩尔质量MN为300-3000的聚亚烷基二醇的双缩水甘油基醚形成的反应产物。然后压缩所述纸并且除去起皱的纸。本发明还涉及粘合剂(i)-(iii)在起皱方法中作为起皱助剂的用途。
摘要（英）：

The invention relates to a method for producing creped paper by gluing a paper web to a creping cylinder with the aid of an adhesive. Said adhesive consists of: (i) a polyethylene imine with a molar mass Mw of between 50,000 and 2 million, (ii) products of a reaction between polyethylene imine with a molar mass Mw of between 500 and 1 million and at least one C14 to C22 alkyldiketene, a monocarboxylic acid, a monocarboxylic acid ester or a monocarboxylic acid chloride and/or (iii) products of a reaction between polyalkylene polyamines with a molar mass of between 300 and 1 million and at least one dichlorohydrin ether or diglycidyl ether of a polyalkylene glycol with a molar weight MN of between 300 and 3000. The paper is then compressed and the creped paper is removed. The invention also relates to the use of the adhesives (i) to (iii) as auxiliary agents in the creping process.
