Preparation of antibacterial cotton fabric using chitosan-silver nanoparticles

Abstract

The aim of this study was to prepare antibacterial cotton fabric using chitosan-silver nanoparticles (CS-AgNPs). CS-AgNPs were used as finishing agent for 100 % pure cotton fabric. AgNPs were prepared by Turkevich method. CSAgNPs were synthesized by mixing chitosan solution with silver nanoparticles. Fourier transform infrared (FTIR) spectrometer technique supported the formulation of CS-AgNPs. Cs-AgNPs crystalline peaks were in perfect agreement with JCPDS card no. 89-3722. Two gram negative bacteria Escherichia coli, Pseudomonas aeruginosa and two gram positive bacteria Bacillus cereus, Staphylococcus aureus were used to test the bacterial efficacy of synthesized AgNPs and CSAgNPs. Scanning electron micrograph of cotton fabric revealed the presence of CS-AgNPs on the surface of cotton fabric. The presence of small amount of silver nanoparticles in the composite was enough to enhance antibacterial activity significantly compared to pure chitosan.

TEXTILE FINISHING WITH CHITOSAN AND SILVER NANOPARTICLES AGAINST Escherichia coli ATCC 8739

“…Table 1 shows the distribution by weight of C, O and nano-Ag particles on the fabric surface. In previous studies, the % by weight of nano-Ag particles deposited on the fabric surface was recorded as 0.006% (Gharibshahi et al 2017) and 0.10% (Arif et al 2015). In our study, the weight of nano-Ag on the surface of the fabric was 0.046% in the coating with shrimp chitosan and 0.06% in the coating with crayfish chitosan.…”

“…The authors concluded that as well as the homogenously and well distribution of nano-Ag particles in the chitosan matrix, also synergistic effects of chitosan and nano-Ag particles caused Ag/chitosan composites to exhibit higher antibacterial activity. Arif et al (2015) measured the antibacterial activity of fabric samples coated with chitosan+nano-Ag particles against S. aureus and E. coli and they found the bacterial reduction rates to be around 98-99%. The authors stated that there was only a slight reduction in antibacterial activity even after 20 washes.…”

Synthesis and Characterization of Freeze Dryer Chitosan Nano particles as Multi functional Eco-Friendly Finish for Fabricating Easy Care and Antibacterial Cotton Textiles

“…These products consist of antimicrobial agents such as silver, quaternary ammonium chloride, and chitosan, and showed anti-bacterial activity against a widespread range of microorganisms [31]. Chitosan is one such poly-cationic biopolymer with high antimicrobial activity and possess distinctive properties such as biodegradability, non-toxicity, cationic nature, wound healing and antimicrobial [4]. For all the above advantages, we have used our previously prepared chitosan nanoparticles (60-100 nm) together with CA as a crosslinking agent to produce multi finished cotton fabrics as detailed in the forgoing sections.…”

“…Chitosan is one of the most attractive highly reactive biopolymers mainly due to the presence of amino and hydroxyl functional groups on its backbone structure, such groups embrace also chemical linking of chitosan to organic and inorganic reinforcing network in hybrid preparation. Chitosan is a natural biopolymer and possess distinctive properties such as biodegradability, non-toxicity, natural abundance, cationic nature, and antimicrobial activity that allow it to be an evocative material for textile industry persistent eco-friendly processes [3,4]. To obtain more benefits of chitosan, new studies have been focused on nanosized chitosan particles.…”

Durable antibacterial cotton modified by silver nanoparticles and chitosan derivative binder

“…Recently, silver nanoparticles (AgNPs), including silver metal and silver oxide (Ag 2 O), have shown great promise in the antimicrobial applications due to their high specific surface area, high activity against a wide range of pathogens, low toxicity for human beings, and low cost [11][12][13][14][15][16][17][18][19][20][21][22]. However, these applications of the AgNPs were also troubled by environmental issues, which is mainly caused by the leaching of Ag ions from the antimicrobial textiles [23,24].…”
