In this study, plain woven fabric was produced using a blend of cotton/flax /polyester (CFP). As it proposes make a textile fabric with unique properties. The purpose of the study was to examine the effect of alkaline treatments using sodium hydroxide and sodium hydroxide/ methanol via conventional and microwave irradiation techniques. Samples were dyed with reactive dye in one bath and measurements of tensile strength, abrasion tendency, air permeability, color efficiency and fastness properties of the fabric were done. The samples showed the advantages of mechanical properties, such as breaking force and elongation, color efficiency, abrasion resistance, fastness properties and air permeability.
