The present invention relates to a textile adhesive production method, which comprises: adding water to vinyl acetate, butyl acrylate and acrylic acid, and carrying out stirring mixing; carrying out a dropwise adding reaction on the raw material after an emulsification reaction, placing into a constant temperature box, and carrying out constant temperature storage; weighing degumming fibroin fiber, adding a calcium chloride solution with a mass concentration of 50%, carrying out mixing dissolving, filtering, and purifying; taking a new reaction container, adding soybean protein and a sodium hydroxide solution, uniformly mixing, and stirring at a room temperature to prepare a soybean protein slurry; and mixing the prepared solutions, adding a curing agent and an antioxidant, uniformly stirring, standing for 20 min, washing, and filtering so as to prepare the adhesive. According to the present invention, the textile adhesive preparation process is simple and perfect, and has the low cost, the textile adhesive is rich in the natural protein fiber so as to provide good affinity to natural fibers, and the soybean protein has good affinity to natural fibers, such that the softness of flocking fabric is substantially improved.
