In order to improve the dye uptake of acid dyes on dark dyeing of nylon fabrics,the nylon fabrics were dyed in one bath with acid dye and dyeing lifting agent L230.The influences of the amount of lifting agent L230,dyeing temperature,dyeing time,dye amount and dyeing pH value on the dyeing property of nylon fabrics were investigated.The dyeing fastness of dyed nylon fabrics was tested.The results show that the effect of pH value on the dyeing of nylon fabric is weakened after the addition of lifting agent,and the effect of lifting agent L230 on the dyeing of nylon fabric is obvious.When the dosage of lifting agent is 1.0 g/L,the dye uptake of nylon fabric is significantly increased.The dye uptake and K/S value of weakly acidic deep-blue 5R and neutral black BL on nylon fabrics increases with the increasing of dyeing time and temperature.The addition of lifting agent has no effect on the dyeing fastness of nylon fabrics.
