  • Patent number: 12071490
    Abstract: The present invention is a process to produce Z-Chitosan to provide consistent and long-lasting antimicrobial, antiviral, antibacterial, antifungal, anti-spore, and anti-odor characteristics, the process comprises steps of preparing a liquid active agent comprising 50 ppm to 5,000 ppm aqueous solution of each of a Chitosan group, a herbal extract group, and a catalyst group using an emulsion crosslinking method for 24 to 144 hours at normal room conditions; preparing a powder form of the active agent by drying the liquid active agent; encapsulating the powder form of the active agent within a plastic, a polymer, a fabric to make a masterbatch of the product, and finally blending 1 to 10 percent of the masterbatch with a batch of plastic, polymer, or fabric to make an antimicrobial product, whereby the product shows antimicrobial and self-sanitizing efficacy for contact time between 2 hours to 24 hours and maintains its antimicrobial efficacy in the scale of years in different environment conditions.

  • Patent number: 9915031
    Abstract: A method for producing antimicrobial paper pulp is provided. The method includes steps of obtaining paper pulp, reducing water content and temperature of the paper pulp, and refining the paper pulp having reduced water content and temperature to improve properties of the paper pulp. The refining may be performed using a refiner with rotating and stationary cutters. The nanocomposite suspension may be added to the refined paper pulp to produce antimicrobial paper pulp. The antimicrobial paper pulp may be drained and pressed to produce paper by applying oil to reduce moisture content of the paper. The paper may be dried without using vapor.
