Title (EN) DISSOLVED AIR DE-BONDING OF A TISSUE SHEET
(FR) DÉLIAGE À L'AIR DISSOUS D'UNE FEUILLE DE SOIE
Abstract:
(EN) Tissue papers and methods of making are disclosed herein. In one aspect, a tissue paper is substantially free of a chemical debonder and has a geometric mean tensile (GMT) in a range between about 500 and about 5,000 g/3 inches (g/3 in.) and a caliper in a range between about 50 and about 350 mils/8 sheets.
(FR) L'invention concerne des papiers de soie et des procédés de fabrication. Dans un mode de réalisation, un papier de soie est pratiquement exempt d'un délieur chimique et présente une traction moyenne géométrique (GMT) dans une plage comprise entre environ 500 et environ 5 000 g/3 pouces (g/3 po) et un calibre compris entre environ 50 mils et environ 350 mils/8 feuilles.
