Nanocellulose-Based Sustainable Dyeing of Cotton Textiles with Minimized Water Pollution.

ABSTRACT: This research aims at minimizing environmental pollution by effluents discharged from current textile dyeing processes. The reduction of pollution is approached with a nanofibrillated cellulose (NFC) dyeing method. In the commonly used exhaust reactive dye bath cotton dyeing process, water effluents are contaminated with unreacted dyes and dyeing formulation auxiliaries amid the consumption of 20 weight units of water per weight unit of colored textile products. It was recently demonstrated that using reactive dye-colored NFC hydrogels-an aqueous dispersion of the NFC pigment-a sustainable dye carrier-results in 6-fold reduction in consumption of water and auxiliaries. Here, we report further developments of this technology. Cotton fabrics and NFC hydrogels inherit a fraction of soluble po
