摘要： A process for manufacturing paper is characterized by the fact that there is introduced into the fibrous composition constituting the starting or raw material, at two or several points, particularly in the wet end, separately from one another, one (or several) cationic starch(es) and one (or several) anionic starch(es) other than a starch phosphate.

摘要： The present invention relates to an aqueous dispersion of pigment(s) and/or filler(s) containing, as an additive, a saccharide composition containing at least 30% of hydrogentated monosaccharide(s) and/or disaccharide(s). The saccharide composition contains at least 75% of such saccharides, in particular sorbitol, mannitol and/or maltitol. The optimum introduction rate is somewhere between 1 and 3%, in dry weight in relation to the dry weight of pigment(s) and filler(s) of the dispersion. The dispersion according to the invention presents a Brookfield viscosity (20° C., 20 rpm) of between 100 and 4000 mPa.s and a viscosity instability index lower than 35%. The dispersion according to the invention can present a very high level of solid matter, for example from 72 to 80% and be used advantageously in numerous industries such as those connected with paper, paint and varnishes, inks, adhesives, detergents, textile materials and leathers, etc. The dispersion can contain various pigments or fillers such as clays (kaolins, smectites), calcium carbonates, talc, titanium dioxide, calcium or barium sulphates or sulfoaluminates.

摘要： This invention relates to a novel composition for the production of planar structures, whereby said composition is based on a cationic amylaceous material and a sulphonated amylaceous such as sulphocarboxylate. The composition can exist in the form of a pulverulent solid mixture or an aqueous suspension in which both amylaceous materials take the form of granules which are swollen or unswollen. Said composition can also exist in the form of an adhesive which can or cannot contain granular structures which are swollen or unswollen and/or complexes which associate both amylaceous materials. Said complexes flocculate and precipitate generally during the solubilization stage which can advantageously consist of a continuous or discontinuous curing stage. The use of said compositions and flocculated/precipitated complexes that they can contain allows planar structures, especially structures made of paper, cardboard or films, to be provided with physical characteristics that meet the needs of current usage in every way. Said compositions can be introduced into a fibrous mass either on one occasion or on a number of occasions at a rate of 2-12 wt. % (sec/sec) for internal treatment of paper.
