  • Alkaline enzyme scouring of cotton textiles
    Publication number: 20030165674
    Abstract: The invention relates to a process for treatment of cellulosic material, as for example, knitted or woven cotton fabric, comprising the steps of preparing an aqueous enzyme solution comprising pectinase, treating the cellulosic material with an effective amount of the aqueous enzyme solution under alkaline scouring conditions; e.g., pH of 9 or above and a temperature of 50° C. or above, in a low calcium or calcium-free environment, yielding a modification of the cellulosic material such that exhibits an enhanced respond to a subsequent chemical treatment.
    Type: Application
    Filed: February 20, 2003
    Publication date: September 4, 2003
    Applicant: Novozymes North America, Inc.
    Inventors: Carl Andrew Miller, Steen Skjold Jorgensen, Eric W. Otto, Niels K. Lange, Brian Condon, Jiyin Liu
