“…The most important methods or techniques for conferring antibacterial activity to textiles may be broadly classified (Vigo, 1994;Mao and Murphy, 2001;Wallace, 2001;Lee et al, 2003;Zhang et al, 2003;Lim and Hudson, 2004;Mahltig et al, 2004;Purwar and Joshi, 2004;Mahltig et al, 2005;Williams et al, 2005;Höfer, 2006;Gao and Cranston, 2008;Dastjerdi and Montazer, 2010;Ibrahim et al, 2010a) as follows: (i) by incorporation of proper bio-active agents into the polymer melts before extrusion; (ii) by surface application (e.g., chemical grafting); (iii) by exhaustion and/or pad-dry-cure for natural substrates (e.g., resin treatment); (iv) by coating technology; (v) by chemical or physical modification of substrate and/or the active agent for chemical bonding; (vi) by spraying or foaming technique; or (v) by using sol-gel or encapsulation in sol-gel particles. Selection of the most appropriate physicochemical (e.g., coating, plasma, or laser surface treatment, microencapsulation) and/or chemical (e.g., grafting, cross-linking, covalent bonding, chelation) methods or techniques is governed by the chemical nature of the active agent, the fiber type, the fabric structure, the available equipment, and the demanded performance properties.…”
