Embodiment Construction
[0030] Below in conjunction with embodiment the present invention is described in further detail.
[0031] Color knitted denim coating dyeing process in the present embodiment comprises the following steps:
[0032] A, carry out pretreatment to dyed fabric: comprise the main processes such as singeing, boiling and bleaching;
[0033] B. Coloring: Use a foam generator to beat the dyeing agent into dyed foam and apply it to the colored surface of the open-width traveling fabric, control the amount of foam supply and cloth speed, so that the amount of liquid in the fabric is 8-15%, and then pass through several groups, Seven groups are preferred, and the drying cylinders at different temperatures are dried step by step at a constant temperature of 70°C to 120°C;
[0034] C. Color fixation: Use a foam generator to beat the color-fixing agent into a color-fixing foam and apply it to the colored surface of step B of the open-width traveling fabric, and control the amount of foam su...
