Process for producing dyed and wrinkled base paper by fourdrinier vat paper machine

The invention belongs to the technical field of papermaking, and particularly relates to a process for producing dyed and wrinkled base paper by a fourdrinier vat paper machine. The production process comprises the following steps of: conveying a pulp board, a chain plate, a pulper, a discharging pool, a pulping machine, a pulp forming pool, a machine chest, a slushing pump, a pressurized screen, a headbox, a net part, a pressing part, a large cylinder, a coiling part, rewinding, packaging and warehousing. The aluminum sulfate and rosin size acidic sizing agent and the food-grade wet strength agent used in the invention maintain good wet strength in the process of the paper sheet passing through the dye, the water absorption amount of the dye meets the use requirements, the moisture entering the wrinkling drying cylinder and the moisture exiting the wrinkling drying cylinder are controlled in place through the raw paper, repeated debugging by a user is avoided, the generation of exposed folds is completely er
