The invention relates to the technical field of dyeing and finishing processes, in particular to a dyeing and finishing process for solving waterproof defects. The dyeing and finishing process comprises the following steps: immersing a fabric in water, adding a refining agent, caustic soda flakes and a cylinder cleaning agent, refining for 30-40 minutes at the temperature of 80-90 DEG C, then cooling to 60-70 DEG C, pressurizing and draining water, and dyeing, and immersing the dyed fabric in water, adding caustic soda flakes, a cylinder cleaning agent and a chelating dispersant, and soaping at 65-75 DEG C for 30-40 minutes. The dyeing and finishing process comprises the step of preventing waterproof defects by adjusting a dyeing and finishing formula and parameters. 本发明涉及染整工艺技术领域，具体涉及一种解决防水疵点的染整工艺。该染整工艺，包括以下步骤：将织物浸入水中，加入精炼剂、片碱和清缸剂，在80～90℃的温度下精炼30～40min，然后降温到60～70℃时进行加压排水，再进行染色处理；将染色处理后的织物浸入水中，加入片碱、清缸剂和螯合分散剂，在65～75℃的温度下皂洗30～40min。该染整工艺包括通过对染整配方和参数的调整防止防水疵点的产生。
