The invention discloses a dyeing process for suspender processing, which comprises the following steps: S1, soaking in clear water, sequentially adding a penetrant, caustic soda, an emulsifier, a whitening agent and hydrogen peroxide for soaking, discharging a mixed solution, cooling, and cleaning with clear water; s2, the sling treated in the step S1 is subjected to water removal in an extrusion drainage mode and then is heated; s3, a high-temperature and high-pressure overflow jet dyeing machine and alkaline dye liquor are adopted for dyeing the suspender treated in the step S2, the suspender is cleaned and refined before dyeing, impurities left on the suspender are cleaned away, meanwhile, the suspender is bleached and deoiled, the follow-up dyeing success rate is increased, meanwhile, curing is conducted after dyeing is finished, and therefore the suspender is obtained. And after drying and shaping, the suspender is soaked in hot water, and the situation that part of dye falls off in the drying process, a
