Development of multifunctional cellulose-containing fabrics has been highly demanded both by the textile finisher and the textile consumer. Herein, proper finishing formulations comprise the following ingredients individually and in combination: a reactant crosslinker (Fixapret ECO), hydrolysed 3-glycidyl-oxypropyltrimethoxysilane (GPTMS), as a cocrosslinker and fixing agent, a flurochemical water/oil repellent agent (Asahi Guard® AG-925), silver nanoparticles dispersion (AgNPs), as antibacterial agent along with metal salt catalyst, especially AlCl

, were applied to various cellulose containing fabrics, using a pad-coating impregnation method, to add new multifunctional properties like anti-crease, water/oil repellent, antibacterial functionality as well as thermal stability. The degree of improvement in the imparted functions is governed by type of substrate, extent of modification and/or crosslinking, amount/location/distribution as well as fixation of the added active ingredients. Also, the obtained results clearly demonstrated that the created multifunctional properties are not seriously decreased even after 15 washing cycles. Various characterization techniques were used, and the possible interactions among the nominated components and the treated substrates were also suggested.
