Building block structure, suit for different weight fabric and different processing.High liquid supply system can increase pick-up of liquid quantity, it makes the fabric suck the chemicals equally and fully.The upper guide rollers of combination steamer are adjusted by frequency conversion transmission. It reduces crinkles due to changes of tension and meets thw requirement of high-density poplin.The fabric is heated enough before folding to insure the chemicals penetrate evenly,This structure makes the saturated steam easy to penetrate and keeps temperature and humidity of the fabric so that it ensures the consistency of the scouring & bleaching.It is not easy to get crinkles Roller width: 1800-3600mmMachine speed: 15-80m/minDrive: PLC, AC motor with inverter
