In this way, we began to study new imitation cotton fibers to replace cotton. This paper is to investigate the influence of the dyeing properties of imitation cotton FDY. It can be concluded from the experiment that the concentration has different effects on the dyeing performance. As the concentration increases from 2 % to 5 %, its dyeing effect will become better and better. The temperature also has an impact on its dyeing performance. This experiment discusses how its dyeing rate will change at temperatures of 85 °C, 90 °C, 95 °C and 100 °C. The experiment shows that the dyeing rate will increase with the increase of temperature. Over time, its dyeing rate will become higher and higher, but when it reaches a certain balance, the dyeing rate will remain constant to a certain value, or even decrease.
