| 摘要 |
<p>The present invention relates to a soft and strong cellulose-based fibrous web, in particular tissue paper, comprising a) cellulosic fibres having a freeness value of more than 26 DEG SR measured according to DIN-ISO 5267/1 (March 1999), b) a water-soluble cationic polymer, c) a water-soluble anionic polymer, and d) a cationic surfactant-based softener, as well as a process for the preparation of these webs which comprises the steps of refining cellulosic fibres to a degree of freeness of more than 26 DEG SR, preferably at least 27 DEG SR, measured according to DIN-ISO 5267/1, adding at least one water-soluble anionic polymer and water-soluble cationic polymer to the refined cellulosic fibres, adding a cationic surfactant-based softener to the cellulosic fibres obtained thereby, and wet-laying and dewatering the cellulosic fibres obtained thereby.The webs obtained are distinguished by a high wet-strength and a suitable balance of other properties such as softness, dry strength and absorbency.</p> |
