step two: opening the water inlet pipe (2), introducing clean water into the water washing tank (1), stopping introducing the clean water when the liquid level of the clean water is close to the water inlet pipe (2), starting the water suction pump (7), operating the water suction pump (7) to pump out the clean water from the water washing tank (1) through the water suction pipe (21) and conveying the clean water to the water storage tank (8), adding desizing enzyme into the water storage tank (8) from the feeding port (9), and uniformly stirring;
step three: starting a first heating layer (17), heating clear water in a water washing tank (1) to 70-85 ℃ by heat emitted by a heating wire, starting a lifting cylinder (29), enabling a movable rod of the lifting cylinder (29) to extend upwards to push a mounting plate (28) to rise, pushing all first guide mechanisms (18) to move upwards through a rotating shaft, driving a fabric (100) to be dyed to move out of a liquid level by the first guide mechanisms (18), rising to be flush with a conveying roller (22), conveying the clear water containing desizing enzyme in a water storage tank (8) to a liquid diversion tank (19), and spraying the fabric (100) to be dyed from a spray head (20);
step four: after spraying is finished, the lifting cylinder (29) contracts to drive the first guide mechanism (18) to move downwards to drive the fabric (100) to be dyed to enter clear water, the lifting cylinder (29) continuously moves to drive the fabric (100) to be dyed to circularly reciprocate to enter and leave the clear water, and stains and impurities on the fabric (100) to be dyed are washed off in the process that the fabric (100) to be dyed moves up and down;
step five: after washing for 10-15min, moving the fabric (100) to be dyed out of the liquid level, draining for 5min, starting a first motor (6) and a second motor (15), wherein the first motor (6) is operated to drive a conveying roller (22) to rotate through a rotating shaft, so that the fabric (100) to be dyed is driven to move forwards, the second motor (15) is operated to drive a main belt pulley (14) to rotate, a belt drives an auxiliary belt pulley (12) to rotate so as to drive a rolling roller (11) to rotate, the fabric (100) to be dyed is rolled, and the fabric (100) to be dyed is pulled to move forwards;
step six: in the process that the fabric (100) to be dyed moves forwards, when the fabric (100) to be dyed passes through the first guide mechanism (18) and the second guide mechanism (23), water is extruded out by the upper guide roller (30) and the lower guide roller (31); starting the second heating layer (25), heating the inner cavity of the pre-shaping box (10) to 140-;
step seven: when the fabric (100) to be dyed is output from the fabric outlet (26), the washed fabric (100) to be dyed is completely wound onto the winding roller (11), the first motor (6) and the second motor (15) are stopped, and the steps are repeated to wash the next fabric (100) to be dyed.
