An eco-friendly route to develop cellulose-based multifunctional finished linen fabric using ZnO NPs and CS network

The study aims to develop a multifunctional finished linen fabric by using an environment-benign, green and sustainable route. The cellulose-based linen fabric has been functionally modified by amino polysaccharide (chitosan, CS), zinc oxide nanoparticles (ZnO NPs), and flower extract of medicinal plant, Bombax ceiba. The NPs were stabilized by the extract on chitosan polymeric layer, which was bound on the fabric through citric acid. Thus, developed finished fabric, at three different pH values, was examined for bending length, tensile strength, crease recovery, UV-protection, antibacterial, and antioxidant activity. The embedded ZnO NPs have been confirmed through FT-IR, Energy dispersive X-Ray spectroscopy (EDX), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results showed effective crease recovery angle (CRA) and hiked UV protection factor (UPR) with splendid percent antibacterial activity against Escherichia coli and Staphylococcus aureus (>90%) and high free radical scavenging ability (80-90%) for the modified fabrics. The durability of the multifunctional properties has also been determined by several launderings. (c) 2021 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.

Automated summary

The study developed a multifunctional finished linen fabric using an environment-friendly approach by modifying cellulose-based linen fabric with amino polysaccharide, zinc oxide nanoparticles, and flower extract. The modified fabric exhibited effective crease recovery, increased UV protection factor, excellent antibacterial activity, and high free radical scavenging ability. The durability of the multifunctional properties was also confirmed after several launderings.
