Tissue paper having an enhanced bulk softness comprises from 0.01 to 5 % of a water soluble polyhydroxy compound, e.g. glycerol, based on the dry fiber weight of the paper. These nonionic polyhydroxy compounds have high rates of retention when applied (120) to the wet-laid tissue web (88) at a fiber consistency of from 10 to 80 % on a papermaking machine (80), followed by drying (100, 108, 110) and creping (111) the web. The tissue paper may further comprise additives such as starch to increase paper strength.
Papier de soie ayant une douceur de parties à haute densité de volume améliorée comprenant entre 0,01 et 5 % d'un composé polyhydroxylé soluble dans l'eau, par exemple du glycérol, sur la base du poids des fibres sèches du papier. Ces composés polyhydroxylés non ioniques présentent des taux élevés de rétention lorsqu'ils sont appliqués (120) sur la feuille continue de papier de soie (88) obtenue par voie humide, à une densité de fibres comprise entre 10 et 80 %, sur une machine à papier (80), avant le séchage (100, 108, 110) et le crêpage (111) de la feuille continue. Le papier de soie peut également comprendre des additifs, tels que l'amidon, pour en renforcer la résistance.
