A Novel Coloration of Polyester Fabric through Green Silver Nanoparticles (G-AgNPs@PET)

Abstract

This paper reports a novel route for the coloration of polyester fabric with green synthesized silver nanoparticles (G-AgNPs@PET) using chitosan as a natural eco-friendly reductant. The formation of AgNPs was confirmed by UV-visible spectroscopy. The morphologies and average particles size of G-AgNPs was investigated by transmission electron microscope (TEM) analysis. The uniform deposition of G-AgNPs on the PET fabric surface was confirmed with scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectroscopy. The thermal properties were investigated using a thermogravimetric analyzer (TGA). The coloration and fastness properties of fabric were found to be significantly improved, a result related to the surface plasmon resonance of G-AgNPs. The antibacterial properties of fabric were also found to be excellent as more than 80% bacterial reduction was noticed even after 10 washing cycles. Overall, the proposed coating process using green nanoparticles can contribute to low-cost production of sustainable textiles.

Electrospun Polyethylene Terephthalate Nanofibers Loaded with Silver Nanoparticles: Novel Approach in Anti-Infective Therapy

“…Furthermore, green synthesis methods could also be applied for the production of silver nanoparticles, thus avoiding the use of potentially toxic reducing agents. Examples of such agents can be found in the literature, most commonly involving chitosan [60] and other polysaccharides, plant extracts [61,62,63], or microbial extracts [64], all exhibiting enhanced antibacterial properties. In the present study, the investigated biomaterials proved to be efficient against the three types of bacteria, both in the planktonic and attached states, thus confirming their potential in anti-infective applications.…”

A state-of-the-art review on coir fiber-reinforced biocomposites

“…Natural ber-reinforced composite materials have received continuous attention due to their industrial application potential. Natural bers are comparatively cheap, renewable, completely/partially recyclable, biodegradable, and ecofriendly, [1][2][3][4][5][6] and synthetic products [7][8][9][10][11][12] are continuously being replaced by natural products. [13][14][15][16] The lignocellulosic ber materials including ax, hemp, ramie, kenaf, jute, coir, hard and sowood materials, and rice husk are the biggest sources of biocomposite ller materials.…”

In-vitro anticancer activity against Caco-2 cell line of colloidal nano silver synthesized using aqueous extract of Eucalyptus Camaldulensis leaves

“…Silver nanoparticles are widely used in many fields especially at medical and health fields [ 5 ] because of their unique physicochemical, and biological therapeutic properties as antibacterial [ 6 , 7 , 8 ] antiviral [ 9 ], antifungal [ 10 ], anti-inflammatory [ 11 , 12 ] and anticancer [ 13 , 14 ]. Silver nanoparticles have been extensively carried out biomedical areas as treatment of wounds [ 15 ] and burns [ 16 ], water purification [ 17 , 18 ], air filter [ 19 ], textile industry [ 20 , 21 ] and healthcare products. In recent years, many eco-friendly methods [ 22 , 23 ] have been employed in the synthesis of silver nanoparticles using biological materials like bacteria [ 24 , 25 ], fungi [ 26 , 27 ] and plant extracts.…”
