Quality of Cotton and cotton/elastane Single Jersey Knitted Fabrics before and after Softening and <i>in Situ</i> Synthesis of Cu-based Nanoparticles

The quality of cotton and cotton/elastane single jersey knitted fabrics before after softening was evaluated through their mechanical properties, pilling, volume electrical resistivity. Elastane-containing have higher bursting elongation stiffness, lower strength, the same or pilling grade, 23–27% resistivities compared to 100% due increased compactness that enables better contact between loops, easier flow charge them. Softening does not affect slightly improves fabric (up 1000 cycles); it decreases fabrics’ stiffness increases strength resistivities. last one significantly decreased in situ synthesis Cu-based nanoparticles on surfaces. Namely, were first treated with sodium alginate whose carboxylate groups crosslinked Cu2+-ions (from CuSO4 solution) further reduced ascorbic acid. In (detected by FESEM) obtaining multifunctional having 3.4–9.6 times resistivities, which are line content Cu reduction (determined using ICP-OES), up 2.5 antioxidant activity provided maximum microbial for E. Coli, S. aureus, C. albicans.
