PAPER-MAKING OR NON PAPER-MAKING USE OF A STARCHY COMPOSITION CONTAINING A SELECTED CATIONIC STARCHY MATERIAL

摘要

The present invention relates to the use as at least one cationic starch of the composition containing the starch material, paper manufacture other than standard mass additives or additive water treatment additives. Fixed nitrogen rate of the composition in this invention is 2% or more, preferably 0.1 to 1.9%, and (wherein the% is expressed as a dry weight for the composition dry weight), a viscosity, determined according to the test A is 1600 mPa. s or more, and preferably characterized in that the 5 ~ 1500 mPa.s. Selected on the basis of the viscosity of the starch composition are also fixed to free nitrogen, a number of other applications, specifically, are useful as additives in papermaking mass. ; Fixed nitrogen, cationic starch materials, the starch composition, papermaking additives, water treatment additives for industrial use
