The treated samples were dyed with three different vinylsulphone reactive dyes. The dyeing was evaluated by <i><span style="font-size:11.0pt;line-height:115%;font-family:" calibri","sans-serif";="" mso-ascii-theme-font:minor-latin;mso-fareast-font-family:"times="" new="" roman";="" mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:minor-latin;="" mso-bidi-font-family:arial;mso-ansi-language:en-us;mso-fareast-language:en-us;="" mso-bidi-language:ar-sa"="">K/S </span></i><span style="font-size:11.0pt; line-height:115%;font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;="" mso-fareast-font-family:"times="" new="" roman";mso-fareast-theme-font:minor-fareast;="" mso-hansi-theme-font:minor-latin;mso-bidi-font-family:"times="" roman";="" mso-ansi-language:en-us;mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">values and fastness ratings while the strength properties were observed in terms of tensile and tear strengths. It has been observed that the dyeability of the crosslinked (resinfinished) fabric substantially increases in presence of PEG 600. The best results are obtained at the optimum resin conc. of 100 gpl, PEG 600 conc. of 140 gpl, curing temperature of 160°C and curing period of 3 min.</span></span>
