US Patent 10214858 Cellulosic material with antimicrobial and defiberization properties

The present invention relates to specialty pulp products produced using bifunctional reagents composed of polymeric chain and end caps. The polymeric chain is preferably a polyalkylene glycol based polymer and the end caps are preferably a cationic quaternary ammonium. The bifunctional reagents are especially useful in making specialty fluff with dual functional properties—easy defiberization and antimicrobial properties. The specialty fluff of the present invention prevents odor by inhibiting bacteria growth and production of organic matters, especially when used in an absorbent article intended for body waste management such as baby diapers and adult incontinence device.
