Abstract
A method for the finishing treatment of a fibrous web, includes applying on the fibrous web a polymer adhesive composition including a combination of optionally hydrogenated saccharides, having a low monosaccharide and disaccharide content, a limited polysaccharide content but a sufficiently high oligosaccharide content between DP 3 and DP 9. The invention also concerns a resulting paper or flat cardboard with enhanced physical, mechanical and/or optical properties.
Claims25
A method for the finishing treatment of a fibrous web, wherein an adhesive composition formed of polymer(s) comprising a combination of optionally partially or completely hydrogenated saccharides is applied to said web, said combination of saccharidees having a glucide spectrum exhibiting:
- a content of monosaccharides and disaccharides of less than or equal to 30%,
- a content of oligosaccharides with degrees of polymerization (DP) of between 3 and 9 of greater than or equal to 30%,
- a content of polysaccharides with a DP at least equal to 10 of less than or equal to 70%,
- these percentages being expressed as dry weight with respect to the dry weight of the whole of the combination of saccharides.

- a content of monosaccharides and disaccharides (DP of 1 or 2) of less than or equal to 30%,
- a content of oligosaccharides with a DP of between 3 and 9 of greater than or equal to 30%,
- a content of polysaccharides with a DP at least equal to 10 of less than 70%,
- these percentages being expressed as dry weight with respect to the dry weight of the whole of said combination of saccharides.
