The invention belongs to the field of technical equipment in the fabric pre-treatment procedure in the printing and dyeing industry, and in particular relates to a rope-shaped desizing, scouring and bleaching combination machine. The rope-shaped desizing, scouring and bleaching combination machine comprises water washing tanks, rolling washing machines, scouring tanks, a J-shaped tank after acid rolling, and a J-shaped tank after hypochlorous acid rolling. The rope-shaped desizing, scouring and bleaching combination machine is characterized by being formed by connecting the water washing tank I, the rolling washing machine I, the scouring tank I, the scouring tank II, the water washing tank II, the water washing tank III, the water washing tank IV, the washing tank V, the rolling washing machine II, the J-shaped tank after the acid rolling, the water washing tank VI, the rolling washing machine III, the J-shaped tank after the hypochlorous acid rolling, the water washing tank VII and the water washing tank VIII in sequence. According to the rope-shaped desizing, scouring and bleaching combination machine, technical flow steps are simple, the operation is reliable, the maintenance is convenient, 3 persons are saved, the energy consumption is reduced by one time, the desizing effect is good, the damage to cloth is lightened, and the operation efficiency is improved by 2.5 times.
