The objective of this investigation was to obtain jute fabrics with enhanced sorption properties (by using simple and cost-effective alkali and oxidative modifications) and a long life cycle. The applied alkali modifications lead to hemicellulose removal and decreased the fibers’ crystallinity, both contributing to enhanced fibers’ sorption properties, i.e., water retention power and degree of fibers’ swelling up to 49 % and 70 %, respectively. A connection between cellulose polymorphs’ (cellulose I and cellulose II) contents (determined by XRD), fibers’ surface morphology (verified by FESEM), fabrics’ crimp, and capillarity of jute fabrics modified with 17.5 % NaOH was established. During the oxidative modifications, significant changes in jute fibers’ chemical composition and structure (i.e., lignin removal and more homogeneous middle lamellae) occurred which further resulted in enhanced jute fabrics’ water retention power and capillarity as well as fibers’ swelling up to 80 %, 75 %,... and 54 %, compared to the raw jute, respectively. In order to move towards a circular economy and to ensure the recycling and re-use of recycled fabrics, the jute fabrics with enhanced sorption properties were evaluated as biosorbents for anthraquinone dye C. I. Acid Blue 111. The obtained results revealed that the jute fabrics’ maximum biosorption capacities for this dye ranged from 12.94 to 18.97 mg/g, while the equilibrium adsorption data were highly consistent with the Langmuir isotherm model. Moreover, based on the predicted dye pKa values, the fabric zeta potential, content of carboxyl and aldehyde groups as well as hydrogen bond intensity (determined by ATR-FTIR), a possible mechanism of the dye biosorption onto jute fabric waste was proposed.
