Title (EN) A SOFT, BULKY ABSORBENT PAPER CONTAINING CHEMITHERMOMECHANICAL PULP
(FR) PAPIER ABSORBANT DOUX, AYANT DU CORPS ET CONTENANT DE LA PULPE CHIMIOTHERMOMECANIQUE
Abstract:
(EN) Soft, bulky, absorbent paper containing at least 20 percent by weight of a high-temperature chemithermomechanical pulp (HT-CTMP), calculated on the total fibre weight. The paper also contains at least 10 percent by weight pulp that exhibits good strength properties, such as chemical pulp and/or recycled fibre pulp, and has a bulk of at least 5.5 cm3/g. The bulk, absorption and liquid-dispersion properties of the paper are enhanced by admixing HT-CTMP with the paper pulp.
(FR) Ce papier absorbant doux et ayant du corps contient au moins 20 % en poids, du poids total des fibres, d'une pâte chimiothermomécanique haute température. Ce papier contient également au moins 10 % en poids d'une pâte présentant de bonnes propriétés de résistance, telle qu'une pâte chimique et/ou une pâte de fibres recyclées, et son bouffant est d'au moins 5,5 cm3/g. On augmente les propriétés de bouffant, d'absorption et de dispersion des liquides de ce papier en ajoutant à la pâte à papier une pâte chimiothermomécanique haute température.
