发明名称 METHOD OF MAKING SOFT PAPER
摘要 Soft paper from cellulose fibres is manufactured by wet-forming a first fibre layer. Thereafter air-borne dry fibres are deposited directly on one or both sides of the wet-formed layer while this is still wet, so that a second and possibly a third fibre layer are formed on the first one. Fibre bindings thereby arise between the layers. The wet-formed fibre layer gives the soft paper its strength, while the dry-formed fibres give a soft surface.
