  • Method for stonewashing fabrics using cellulase
    Patent number: 8198068
    Abstract: A method of forming localized variation of color density in the surface of a dyed cellulosic fabric with reducing back staining, with a composition comprising a cellulose having the amino acid sequence of SEQ ID NO: 2 or an amino acid sequence having at least 75% sequence identity with SEQ ID NO: 2 is provided. A method for biopolishing a cellulose-containing fabric by using the new endoglucanase is also provided.
