Antibacterial ilver containing materials can be applied in medicine for f infections on the burn treatment [2,3], prevention of onization on catheters [4,5] and elimination of micron the textile fabrics [6,7] as well as disinfection in water 8]. Polyethylene glycol (PEG) is frequently used in polyproduction to improve the biocompatibility of its film ide range of molecular weights, excellent solubility in dium, low toxicity, chain flexibility and biocompatibiles [9] PEG was able to act both as reducing and stabilizer ral research studies [11,12] researchers proposed that n of PEG exhibits high reducing activity and provides ility in forming AgNPs. These can effectively prevent ion of AgNPs. The reducing reactivity of PEG is very its molecular weight. l reduction method is widely used to synthesize AgNPs ts readiness to generate AgNPs under gentle conditions ity to synthesize AgNPs on a large scale [13].

AgNPs by green synthesis approach has advantages over physical and chemical approaches as it is environment-friendly and cost effective in addition to the fact that the conditions of high temperature, pressure, energy and toxic chemicals are not required in the synthesis protocol [14].

Current work is undertaken with a view to establish a green strategy for synthesis of AgNPs which are suitable for functionalization of cotton fabrics. The strategy is based on utilization of sugar as reductant and PEG as stabilizer. Variation in the formation of AgNPs as well as in their size, shape and size distribution by

PEG molecular weight and concentration of both AgNO3 and sugar – were assessed using UV–vis and TEM. Application of AgNPs colloidal solution to cotton fabrics in presence of BTCA crosslinking agent and SHP catalyst is made and, functionalization of the fabrics brought about by such application is determined using SEM, crease recovery angle, tensile strength and antimicrobial activity. 2.
