Multi-Finishing of Polyester and Polyester Cotton Blend Fabrics Activated by Enzymatic Treatment and Loaded with Zinc Oxide Nanoparticles

Abstract

The present work discusses the possibility of applying enzymatic treatments for fabric surface activation that can facilitate the loading of zinc oxide nanoparticles (ZnO NPs) onto polyester (PET) and polyester cotton blend (PET/C) fabrics prepared by sol-gel method. Activated polyester fabrics loaded by ZnO NPs were investigated by the use of scanning electron microscopy (SEM), electron dispersion emission X-ray (EDX) and Fourier transformed infrared spectroscopy (FT-IR). The functionality of activated polyester fabrics loaded by ZnO NPs was evaluated by analyzing its antimicrobial activity and UV protection efficiency. Antimicrobial activity of activated polyester fabrics and loaded by ZnO NPs was tested against Gram-positive (Bacillus mycoides), Gram-negative (Escherichia coli), and nonfilamentous fungus (Candida albicans). The level of UV protection was verified by the UV protection factor (UPF) of polyester fabrics. Activated post-treated polyester fabrics exhibited outstanding antimicrobial and UV protection efficiency. The achieved antimicrobial function and UV protection on the polyester fabrics are durable with repeated laundering processes even after five washing cycles.

Ag nanoparticles-based antimicrobial polycotton fabrics to prevent the transmission and spread of SARS-CoV-2

“…[46] It is observed for the modified polycotton in relation to the non-treated polycotton the displacement of the band located at 1338 cm -1 , as well as the decrease of the band located around 647 cm -1 , referent to in-plane bending of O-H mode from the glycosidic units and deformation of the OH, respectively. [48,49] These shifts, as well as the appearance of new bands in the FTIR spectra of the modified polycotton are due to interactions between polycotton and Ag-based antimicrobial additives. [50][51][52] To observe morphological changes in polycotton fibers, FE-SEM measurements were performed (Figure 3).…”

“…The UPF values were calculated according to the Australian/New Zealand Standard (AS/NZS-4399-1996). UPF values were calculated, and the protection category is classified as follows: (0-10) non-ratable, (15-20) good, (25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) very good, and (40-50, +50) excellent protection categories [37].…”

“…New functional performance can be achieved by enzymatic treatment that modifies the treated cloth's surface properties by increasing the amount of free hydroxyl and carboxylic groups [22,23,24]. Furthermore, more hydroxyl and carboxyl groups facilitate the nanoparticles' ability to stick firmly to the textile surface [25].It is thought that this technology's use is straightforward and safe for the environment, opening the door to the direct use of fibre waste to create intelligent, functional textiles for a range of cutting-edge uses. The functional fabrics created by this bio-nanotechnology are anticipated to have benefits for the biosensor, packaging, and wastewater treatment industries.…”
