The factors of dyeing technology for PET knit fabrics using liquid flow dyeing machine include the dye exhaustion property of PET fiber and liquid flow parameters in the dyeing machine. This article is focused on: 1. The relationship between the concentration of disperse dyes and critical temperature zone, 2. The effect of pump flow on fabric running speed and even dyeing. As the results proved 1, the concentration of disperse dyes in the PET dyeing got lower with lower critical temperature zone 2. In the adjustment of dyeing pump flow and nozzle pressure, the running speed of pump at the same nozzle pressure did affect the dyeing flow with the differential rate of ± 10% while the fabric running rate with lower rate 3. The application of fabric running speed and nozzle pressure was influenced by the flow rate. Therefore, the optimization of dyeing process should combine the three components of fabrics, dyes and dyeing machine, in order to achieve the aims of energy saving and quality improvement.
