The dyeing rate of nylon with dyeing machine is fast and exhaustion rate is high, but it is also easy to have defects such as uneven dyeing, color mismatch and poor dyeing fastness.

According to the process test of small sample dyeing machine in the laboratory, the dye series with similar dye uptake curve and affinity, good compatibility and suitable for the production machine are selected. Nylon dyeing has high process requirements. The process conditions are the important factors affecting the color light and levelness of the dyed products. The reasonable process should be formulated from the aspects of temperature, bath ratio, pH value, selection and dosage of leveler Control the initial dyeing temperature and heating rate, determine the appropriate bath ratio, determine the appropriate bath ratio, control the pH value, pay attention to the selection and dosage of levelling agent.

Unreasonable technology is easy to produce defects such as poor level dyeing, color flower, color willow, color difference and poor fastness. Through standard proofing, color matching and other operations, reduce the differences between large and small samples, and improve the rate of superior products.
