Large scaled strategy for natural/synthetic fabrics functionalization via immediate assembly of AgNPs

Multi-functionalization of textile to protect against environmental factors and/or add fashionable characters is newly an enjoyable and interested field. One of the most challenges faces such process, is functionalization of natural and synthetic fabrics using the same technique/method. The current study focused on utilization of one applicable technique to functionalize both of natural and synthetic fabrics including linen, silk, nylon and PET. Silver nanoparticles (AgNPs) were in-situ deposited onto fabrics using sodium citrate as reducing agent. Fabrics macromolecules were stabilized the produced AgNPs which were inserted in fabric structure. Functions of the treated fabrics were tested against coloration and UV transmission radiation. The maximum and lowest Ag contents on fabrics were recorded for silk (12.05 g/kg) and nylon (2.65 g/kg), respectively. Except PET, fabrics macromolecules could be shared in the reduction process of Ag ions. Under electron microscope, crystalline - cupic AgNPs was seen on silk surface, while, agglomerated particles were formed on PET surface. Fabrics were acquired yellowish color with good fastness after AgNPs incorporation. UV transmission radiation through fabrics was reduced for all fabrics after treatment and PET showed highest UPF of 30.4. AgNPs-fabrics exhibited antimicrobial properties and followed the order of silk > linen > nylon > PET. (C) 2016 Elsevier Ltd. All rights reserved.
