Basic composition for the manufacture of a flexible and porous product

The invention relates to a sheet obtained by a papermaking process and usable as a product that can be substituted for conventional products referred to as impregnated glass covering products. The sheet essentially contains cellulose fibers, non-cellulose fibers, a thermoplastic powder of specified grain size, and a binder. It is optionally covered with a layer of plasticizer for the thermoplastic powder. Its resistance to traction-delamination increases with grain size. It is applicable as a backing, in particular to floor or wall coverings.

Sheet prepared by wet means and usable as a backing for a covering

The process for producing a tridimensional piece from an aqueous suspension containing at least a thermoplastic resin and reinforcing fibers, comprises the following steps:

The invention relates to a paper sheet obtained essentially from (parts by dry weight)

Paper sheet, process for preparing same and applications thereof

The invention relates to a treatment process for improving the dimensional stability of a fibrous sheet obtained by papermaking process, and of which at least part of the fibers are cellulosic fibers, said process consisting in impregnating the sheet with a chemical composition containing at least one wetting agent and one binder.

Process for the treatment of a fibrous sheet obtained by papermaking

100 parts by dry weight of latex, approximately, are used for about 45 to 140 parts by dry weight of fibrous mixture. Manufacture particularly by double flocculation (addition of each flocculating agent partly before and partly after the addition of latex). Very good properties, particularly breakage strength and delamination resistance.
