    Abstract: Disclosed is a process for preparing a paper web. The paper web is prepared from a low-grade furnish, which contains low-grade pulps, such as recycled pulp and/or groundwood pulp, and which, in one preferred embodiment, is a newsprint furnish. In accordance with the disclosed process, a pre-flocculated filler is added to the furnish prior to forming the paper web from the furnish. Filler will be retained in the web, and retention of undesired components of the furnish in the web will be reduced as compared with newsprint in which a filler is incorporated via conventional processes. Another embodiment contemplates the incorporation of a pre-flocculated coated broke slurry into a paper furnish prior to paper formation. The paper web formed via the process of the invention will have improved properties as a result of the incorporation of the pre-flocculated filler or treated broke into the web.

    Abstract: A process whereby a gelatinized starch having a cationic reagent chemically bound to the starch backbone and a reduced viscosity is prepared by (1) gelatinizing starch and substantially simultaneous with gelatinization reacting said treated starch with an alkyl or alkenyl amine and a water soluble oxidant or (2) simultaneously reacting an alkyl or alkenyl amine and a water soluble oxidant with a gelatinized starch. The process is conducive to the on-site preparation of a thinned cationic starch derivative which can be utilized without additional treatment as a papermaking additive, textile size, waste water treatment, tailing flocculent, etc.

    Abstract: A process for preparing a cationic starch dispersion wherein an alkaline, gelatinized starch is reacted with a cationic reagent either concurrently with, or subsequently to, the cooking process resulting in a product in which the cationic reagent is chemically bound to the starch molecule. The process is conducive to on-site preparation of a cationic starch derivative which can be utilized without additional treatment as a papermaking adjunct, textile size, waste-water treatment or tailings flocculent, etc.
