The invention discloses a cotton knitted fabric short-process
dyeing and finishing process which comprises the steps of pre-
processing,
dyeing, and
softening after-finishing. The step of pre-
processing comprises the process of placing a cotton knitted fabric into pre-
processing finishing liquor with the bath ratio being 1:8 at
room temperature, raising the temperature to 100 DEG C at a rate being2 DEG C / min, and preserving heat for 30 to 45min; the step of
dyeing comprises the process of feeding the fabric at
room temperature, adding a leveling agent after 5min, adding a
reactive dye after 10min, raising the temperature to 60 DEG C at a rate being 1 DEG C / min, adding 1 / 2 the total use amount of
anhydrous sodium sulphate, preserving heat for 15min, then adding 1 / 2 the total use amount of
anhydrous sodium sulphate again, continuing to preserve heat for 15min, adding
sodium carbonate, continuing to perform dying for 30 to 60min, and performing cooling and
water washing; the step of soaping is carried out under the conditions that the bath ratio is 1:8, the concentration of a soaping agent is 2g / L, the temperature is 95 DEG C, and the time is 10min; and the step of
softening and setting comprises the process of padding the soaped cotton knitted fabric in 15 to 30g / L
silicone oil
softening agent finishing liquor, and performing stentering and
drying through a setting
machine at thetemperature
ranging from 180 to 190 DEG C and at the speed
ranging from 20 to 35m / min.
