The addition of nonion surfactants into dyebath decreases both the affinity of disperse dyes to polyester microfiber , and the absolute values of entropy and heatofdyeing;
To ensure the dyeing quality process of heating, heat preservation, watering and draining should be controlled strictly.
为了保证漂染质量，需对漂染过程中的升温、保温、加水、排水等过程进行严格的控制。
