Dyeing and finishing method of cotton and T400 interwoven elastic fabrics

The invention discloses a dyeing and finishing method of cotton and T400 interwoven elastic fabric, and relates to the technical field of dyeing and finishing of elastic fabrics. The dyeing and finishing method is characterized by comprising the following steps: firstly, singeing; secondly, desizing; thirdly, mercerizing; fourthly, presetting; fifthly, dyeing; sixthly, color fixing: firstly, heating 0.5 to 0.8 weight percent (owf) of color fixing agent to 40 to 50 DEG C; then putting the dyed fabric into the color fixing agent, controlling the water bath ratio at 1 to 10, carrying out color fixation for 20 to 30 minutes, taking out and then dehydrating; carrying out ultraviolet drying on the fabric at the drying temperature of 150 to 160 DEG C for 2 minutes; putting the fabric into a colorfixing agent chassis and enabling the fabric to absorb the color fixing agent again; and, after an evenness padder presses residual liquid, drying through ultraviolet rays at the drying temperature of 155 to 160 DEG C for 2
