The aim of this study was to determine feasibility of utilizing greige (non-bleached) cotton comber noils in the development of hydroentangled cotton fabrics for certain end-use products and thereby to promote an economically and environmentally efficient utilization of cotton in sustainable textile products. The data from the feasibility study show that greige comber noils can be efficiently processed into nonwoven fabrics using an air-laid system for preparing a fibrous batt to feed a down-stream hydroentangling system. Furthermore, the study has shown that, for certain specific end-use applications where bleaching is required, the hydroentangled greige cotton fabric can be efficiently bleached without the customary costly and time consuming cotton scouring process. The elimination of the scouring process was made possible by the removal of cotton's natural hydrophobic contaminants (waxes) by optimizing the hydraulic pressure/energy metrics of the hydroentanglement process of producing nonwoven fabrics.
