The invention discloses a pretreatment method of a novel wet-process flower basket. The pretreatment method comprises the following steps: (a), generating ozone by an ozone generator, enabling the generated ozone to enter an ozone and hydrochloric acid tank through an ultrapure water pipeline, and controlling the concentration of the ozone at 1-100ppm; (b), controlling the concentration of hydrochloric acid at 0.01-10mol/L, controlling the temperature of a chemical liquid in the ozone and hydrochloric acid tank at 20-50 DEG C, and uniformly mixing the ozone and the hydrochloric acid in the ozone and hydrochloric acid tank in a bubbling manner; (c), immersing the novel wet-process flower basket in the chemical liquid in the ozone and hydrochloric acid tank, soaking for more than 24h. By thepretreatment method, pretreatment of the novel wet-process flower basket through the existing lye tank can be replaced, a production enterprise can be helped to make full use of the conventional tank-type texturing machine, the utilization efficiency of the tank-type texturing machine is improved, the production progress is accelerated, and the economic benefits of the production enterprise are increased.
