Functionalization of cotton fabric with ZnO nanoparticles and cellulose nanofibrils for ultraviolet protection

Abstract

A simple impregnation method was employed to obtain functional cotton fabric based on a zinc oxide (ZnO) and cellulose nanocomposite. The cellulose nanofibril suspension was utilized to reduce the agglomeration of ZnO nanoparticles (ZnO NPs) and bind them to the surface of the fiber. Scanning electron microscopy and inductively coupled plasma mass spectrometry were used to confirm the presence of ZnO NPs on the surface of the fiber. The treated cotton fabrics exhibited high ultraviolet protection factor values, which were still higher than 50 even after 30 standard washing cycles. Furthermore, the treated samples showed a modest antibacterial effect due to the presence of ZnO NPs. Meanwhile, the treated cotton fabrics showed a decrease (less than 30%) in air permeability.

Transforming textile waste into nanocellulose for a circular future

“…Moreover, the structural similarity between CNFs and cotton fabric facilitates intermolecular hydrogen interactions, enhancing the adhesion of ZnONPs to cotton fabrics and potentially preventing NP leaching during laundering. 130 The evolution of self-cleaning textiles, from earlier superhydrophobic materials to more recent photocatalytic ones, has garnered increasing interest. Photocatalytic activity relies on lightinduced reactions of oxidation and reduction, leading to the breakdown of dirt.…”

Polysaccharides and Metal Nanoparticles for Functional Textiles: A Review

“…Thus, the negative charges of the hydroxyl and carbonyl groups present on CNFs interact with Zn through electrostatic interactions, reducing NP aggregation. Additionally, due to their structural similarity, CNFs and cotton fabric create intermolecular hydrogen interactions, strengthening the adhesion of ZnONPs to cotton fabrics, potentially avoiding NP leaching during the laundering process [ 129 ]. From the earlier superhydrophobic to the more recent photocatalytic materials, self-cleaning textiles have gained increasing interest.…”
