Soft and strong cellulose-based fibrous web, comprises n a) cellulosic fibres having a freeness value of more than 26° SR measured according to DIN-ISO 5267/1 (March 1999), n b) a water-soluble cationic polymer, n c) a water-soluble anionic polymer, and n d) a cationic surfactant-based softener. n The webs are prepared by n refining cellulosic fibres to a degree of freeness of more than 26° SR measured according to DIN-ISO 5267/1, n adding at least one water-soluble anionic polymer and water-soluble cationic polymer to the refined cellulosic fibres, n adding a cationic surfactant-based softener to the cellulosic fibres obtained thereby, and n wet-laying and dewatering the celulosic fibres obtained thereby. |
