The present invention relates to a process for application of chemicals on textile materials for removing surface chemicals and finishes from textile materials which comprises the following steps: reducing the textile materials to an appropriate size; applying a first catalyzed vapor to the textile materials at a predetermined temperature; penetrating the textile materials at a predetermined temperature; applying a second catalyzed vapor to the textile materials; blending the textile materials; applying a third catalyzed vapor to the textile materials in the one or more blending boxes and dwelling the fabric at a predetermined temperature for a predetermined period of time; and applying a blast of cool air to the one or more blending boxes to stop chemical actions in the textile materials and then transporting the textile materials to next station for further deconstruction processing.

A process for treatment of cellulosic material, for example, knitted or woven cotton fabric or yarn, comprises treating cellulosic material with a pectinase and a surfactant.
