step S5: carrying out high-temperature high-pressure spray fumigation treatment on the bulked real silk fabric; and (3) drying the real silk fabric subjected to fumigation treatment in a drying chamber, and drying in the drying chamber.
2. The method for soft finishing silk fabrics according to claim 1, wherein the softening agent in the step S1 comprises the following components in parts by weight: 5-10 parts of pyridine quaternary ammonium salt derivative, 1-4 parts of acrylamide, 2-9 parts of thickening agent, 10-20 parts of nonionic surfactant and 66 parts of water.
3. The real silk fabric soft finishing method according to claim 2, characterized in that the preparation process of the softening agent in the step S1 is as follows: cooling water to below 40 ℃, adding a pyridine quaternary ammonium salt derivative into the cold water below 40 ℃, dissolving the pyridine quaternary ammonium salt derivative to obtain a solution A, adding acrylamide and a thickening agent into the solution A, stirring while adding, and finally adding a proper amount of a nonionic surfactant; filtering, standing and purifying to obtain the finished product of the softening agent.
4. The method for soft finishing real silk fabrics as claimed in claim 3, wherein the method for heat setting finishing in the step S3 is as follows: establishing a heat setting process model of the real silk fabric according to the relation among the parameters, the heat setting quality indexes and the process parameters of the real silk fabric; obtaining a heat setting quality index according to the heat setting process model by taking real silk fabric parameters and heat setting process parameters as initial conditions; placing the real silk fabric in a setting machine, heating to 150-200 ℃, and setting at a speed of 15-25 m/min.
5. The method for softening and finishing silk fabrics according to claim 4, wherein the drying treatment in the step S5 is as follows: preheating and drying air in a drying chamber, then reheating and heating the preheated and dried air, injecting the preheated and dried air into a drying barrel, removing moisture of a drying agent in the drying barrel, and conveying the dried and heated air to the surface of the silk fabric through a pressurizing module.
6. The soft finishing method for silk fabrics according to claim 5, characterized in that the nonionic surfactant comprises: alkylphenol ethoxylates, fatty acid polyoxyethylene esters, and the like.
