Title: PROCESS FOR PROVIDING ANTIMICROBIAL TREATMENT TO NOV-WOVEN FABRICS
Abstract:
An apparatus and process for disinfecting, and, optionally, sterilizing, fibers and non-woven materials produced from the fibers is disclosed, as well as processes for converting fibers into disinfected and/or sterilized non-woven materials. The process involves contacting the fibers and/or non-woven materials with high temperature steam, and then with UV light, which is preferably UV-C light, or another disinfectant process, such as ozone treatment. The process can also involve process steps such as blending fibers, applying fibers to an air card, subjecting the fibers to one or more carding steps, subjecting the carded fibers to non-woven process steps, and chemically treating the fibers and/or non-woven materials. The resulting non-woven materials can be used, for example, in personal care, baby care (including baby wipes), cosmetic applications, household cleaning, automotive, industrial cleaning applications, industrial uses, and the like.
