    Abstract: This invention is directed to methods for the treatment of cellulose-containing fibers and yarn to provide protection to the cellulose from attack by enzymes. The method comprises the steps of exposing cellulose-containing fibers and yarn to an aqueous solution of an enzyme-repelling chemical to give the fibers or yarn a protective coating, and using the protectively coated fibers and yarn to prepare cloth or fabric. In another embodiment, the method of the invention comprises the step of exposing a fabric comprising cellulose-containing yarn to an aqueous solution of an enzyme-repelling chemical to give the fabric a protective coating. The invention also encompasses cellulose-containing fibers and yarn, including cotton, having a protective enzyme-repelling coating. The invention is further directed to denim fabric comprising cotton fill yarn having a protective enzyme-repelling coating. Such denim fabric, and any garments made therefrom, will exhibit greater strength and durability following the stonewashing procedure as compared to denim made from uncoated yarn.

    Abstract translation: 本发明涉及用于处理含纤维素的纤维和纱线的方法,以保护纤维素免受酶的侵蚀。 该方法包括以下步骤:将含纤维素的纤维和纱线暴露于抗驱虫化学品的水溶液中,以使纤维或纱线成为保护涂层,并使用保护性涂覆的纤维和纱线来制备布或织物。 在另一个实施方案中,本发明的方法包括将包含含纤维素纱线的织物暴露于排斥斥酸化学品的水溶液的步骤,以给予织物保护涂层。 本发明还包括含有纤维素的纤维和包含棉花的纱线,其具有保护性的防止排斥涂层。 本发明进一步针对包括具有防护性驱蚊涂层的棉纱线的牛仔布织物。 与由未涂布的纱线制成的牛仔布相比,这种牛仔布以及由其制成的任何衣服将在石膏洗涤程序之后表现出更大的强度和耐久性。
