Antimicrobial activity of AgCl embedded in a silica matrix on cotton fabric

Triclosan Modified Stable Melamine Resin as Long-Lasting Antimicrobial Agent.

“…During the process silver nanoparticles leached from the surface, which as a result after few washing surface, becomes inactive and antimicrobial efficiency is reduced. An excellent method was developed by inserting AgCl in silica matrix but this method had also limitation as well because antimicrobial property was lost after several washing [29]. An AATCC Atlas Launder-O-Meter was used for to determine the washing characteristics of currently used method.…”

“…Antimicrobial Activity:-Branched polymers, including star-shaped, dendritic and hyper-branched architectures, have attracted attention as potential antimicrobial agents [28].AATCC 100 standard method was used to evaluate the antimicrobial activity [29].Bacterial strains like Escherichia coli(Gram negative) and Staphylococcus(Gram positive) were used as testing bacterial strains. Untreated control, triclosan treated and functionalized melamine resin treated swatches of cotton fabrics were inoculated with 1-2 × 10 5 CFU (each experiment was performed for separate bacterial strain) of bacteria and 1.0 ml of broth culture of nutrients were incubated for 2 h at 37 o C, then shaked in neutral solution for separating bacteria from cotton swatches.…”

Modification of cotton fabric with graphene and reduced graphene oxide using sol–gel method

“…This ensures retaining of the original ''textile'' character and appearance of coated textiles. At the same time, the silica matrices can be filled with nanoparticles (Abidi et al 2009;Klemenčič et al 2013;Kowalczyk et al 2015a;Tarimala et al 2006;Tomšič et al 2009). Binding the thin coatings prepared by the sol-gel method to the fiber surface can be significantly improved by using to preparation of film-forming sols the proper organo-silicon precursors, having active functional groups capable of physical or chemical interactions with functional groups on fibers surfaces (Textor and Mahltig 2008), mainly hydroxyl groups in the case of cellulose and polyester fibers.…”

Multifunctional Textiles – Modification by Plasma, Dyeing and Nanoparticles

“…Also the use of salt (NaCl) improved a uniform distribution of silver particles on the fibers' surface which consequently improved antimicrobial effectiveness of fabrics. A difference between pad-dry-cure and exhaustion method on adhesion and antimicrobial activity of fabrics was performed with commercial silver nanoparticles and a reactive organic-inorganic binder [45]. Results revealed that using the same initial concentration of silver, the pad-dry-cure method resulted in a much lower quantity of adsorbed silver nanoparticles in comparison to the exhaust method.…”

“…Textile materials with an antimicrobial effectiveness are used for medical, military and technical textiles, textiles for sports and leisure and bedding. At nanotechnology researches in textiles, different forms of silver were used, such as metal silver nanoparticles, silver chloride (AgCl) and composite particles of silver and titanium dioxide (Ag-TiO 2 ) [3,24,25,27,[38][39][40][41][42][43][44][45][46][47]. In the case of antimicrobial efficiency, the surface coating of nanosilver on titanium dioxide maximizes the number of particles per unit area in comparison with the use of an equal mass fraction of pure silver [48,49].…”
