<span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" calibri;mso-fareast-theme-font:minor-latin;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"="">Direct dyeing and anticrease finishing of jute fabrics were carried out in a single-step process under acidic conditions with a view to economized dyeing and finishing. The properties of the finished fabric, viz. colour strength, crease recovery and wash fastness were comparable to those of the fabrics dyed and finished by the conventional double-step process. Work on optimizing the process parameters viz. catalyst concentration and curing temperature, was also carried out. The duration of curing was kept constant in all the experiments. Incorporation of acrylamide in the padding bath of single-step process improved the colour yield.</span>
