(3) dyeing and finishing
Singeing: selecting a gas singeing machine, and treating the woven fabric in a positive-negative mode at the flame temperature of 800-900 ℃ and the vehicle speed of 80-90 m/min;
dissolving: dissolving in a dye vat, wherein the concentration of sodium hydroxide in the dissolving solution is 15g/L, the temperature is 95 ℃, the dissolving time is 60min, after the dissolving is finished, washing for 2 times by hot water at the temperature of 90-95 ℃, and then drying, wherein the drying temperature is 140-150 ℃;
tentering and setting: setting temperature is 180 ℃, and vehicle speed is 20-55 m/min;
(4) air soft finishing
After the finished fabric is finished by the air soft flapping finishing machine, the bulk acrylic yarn is filled in the interlayer of the fabric in a loose fiber state, and the technological parameters of the air soft flapping finishing machine are as follows: the temperature is 90-95 ℃; the vehicle speed is 20-35 m/min; the upper air volume is 80% and the lower air volume is 65%.
