Abstract

L'invention concerne des procédés d'adoucissement de la pâte cellulosique faisant appel à des agents adoucissants chimiques ou des agents défaisant des liaisons. Ces procédés comprennent des compositions contenant des esters d'acide alkyle inférieurs ou des esters cycliques de composés polyhydroxylés, et n'affectent pas la capacité d'absorption des produits en fibre cellulosique et des produits correspondants. Le procédé décrit dans l'invention peut également être utilisé avec des agents plastifiants de cellulose, tels que le glycérol, les mono- et di-saccharides, le glycol et les oligomères correspondants. Ce procédé utilise de la fibre cellulosique qui est plus facile à deserrer (redéfibrer) et qui permet donc de densifier les coussins d'air formés par les fibres individualisées résultantes, sans affecter la capacité d'absorption.
