In this research work , the dyeability of acrylic fabric with direct dyes and copper sulfate and evaluation of their antistatic property was investigated . On the acrylic fabrics , pre-mordanting ,dyeing and post-mordanting treatments was carried out . The effect of different factors that may affect the dye affinity of acrylic fabrics such as composition of copper sulfate with Rongalite , Lodigol , acid and time-temperature conditions in pre-mordanting stage and the effect of dyeing PH range , water hardness , using DMF on the acrylic fabric before dyeing , time boiling in dyeing stage ,…was studied . In last , washing fastness of post-mordanted acrylic fabric and fixed by Fixanol PN and antistatic property of untreated , pre-mordanted , dyed and post-mordanted was measured . It was shown that in pre-mordanting stage , the effect of using Rongalite , Lodigol and acid accompanied by copper sulfate and in dyeing stage the, changes of PH , hardness water , boiling time from one direct dye to other direct dye is different . Using DMF on pre-mordanted acrylic fabric before dyeing decrease dye affinity . Different percentage of copper sulfate on dyed acrylic fabric were used to increase washing
