Production technology rope ring-dyeing dark-blue weaving fabric

The invention discloses a production process of a rope ring-dyeing dark-blue weaving fabric. The production technology comprises that (1), the vehicle velocity V is 20.0-30m/min; (2), blooming and boiling are conducted for one process at the temperature of 60-90 DEG C; hot water rinsing is conducted for one process at the temperature of 60-80 DEG C; water rinsing is conducted for one process; dying is conducted by using indigo blue for 14-16 processes; water rinsing is conducted for three processes; softening is conducted for one process at the temperature of 60-80 DEG C and drying; (3), a dying groove contains 0.9-3.0g/L of indigo blue, 2.0-3.52g/L of NaOH, 0.8-2.5g/L of sodium hydrosulfite, 8-10g/L of boiled material, 80-120g/L of a softening agent, 3-10g/L of amino silicon oil and 11-12g/L of pH; the electric potential is 740-760; and (4), the padder pressure is 5.5MPa-6.5MPa. The bundle-type ring-dyeing dark-blue yarn dyed fabric is modified based on an existing Morrison beam dyeing machine, high dye-uptake of jean cloth is achieved, and the requirement of dark-blue jean cloth is met.
