Latest Patents
Gaines holds a patent for a "Method for preparation of cationic cellulose." This invention involves creating a fibrous, cationic cellulose pulp product through a specific process. The method entails treating a water suspension of cellulosic fiber under alkaline conditions with a condensate of epichlorohydrin and dimethylamine. Notably, up to 30 molar percent of the dimethylamine may be substituted with a crosslinking agent, such as ammonia or a lower aliphatic diamine. The process can be executed at room or elevated temperatures, and it is practical to introduce the condensate during later alkaline stages of a bleaching process. The resulting product demonstrates significantly improved retention of acid and other anionic dyes, as well as superior retention of certain pigments and latices without the need for additional cationic aids.
