Nanosilver coating on hemp/cotton blended woven fabrics mediated from mammoth pine bark with improved coloration and mechanical properties

Abstract

A novel approach has been adopted for synthesizing green silver nanoparticles (AgNPs) over hemp/cotton blended woven fabrics. The nanosilvers were synthesized from the bark of mammoth pines (Sequoiadendron giganteum) through ensuring in situ synthesis protocol. The synthesized AgNPs displayed brilliant color appearances on the surfaces of fabrics due to LSPR (localized surface plasmon resonance) effects. The deposited AgNPs were quantified by X-ray fluorescence (XRF) tests for the solid samples and found significant presence of metallic silvers on the surfaces. The control and colored materials were characterized in terms of scanning electron microscopy (SEM) analysis, SEM-deployed EDX (energy-disruptive X-ray) and associated elemental mapping investigations and provided the explicit signal of AgNPs presence in the coated materials. The colorimetric data of the developed products were also investigated for the confirmation of developed color in the fabric samples. The perceived colorimetric data also shown the brilliant, bright, and stable coloration effects on nanosilver incorporated specimens. Moreover, the color fastness results also demonstrates a stable coloration effects on the fabrics due to the strong binding of AgNPs with the cellulosic materials. Statistically, coefficient of variations (R²) for all the colorimetric data also investigated to identify their relationship with nanosilver concentrations and found they are significant. Overall, this current research is going to report a novel, innovative, and sustainable coloration approach on hemp/cotton blended woven fabrics, which would facilitate the dyeing industries significantly.
