[0051] S1. Preprocessing

[0052] a. Firstly, the raw materials for preparing the degradable fibers 18 are pretreated to obtain the degradable fibers 18, and then the degradable fibers 18 are selected for mixed weaving to form cloth;

[0053] b. Then cut the edge of the cloth and remove the hair on the surface of the cloth to remove the excess hair on the surface of the cloth;

[0054] c. Then wash the cloth with water for 5 to 8 times to ensure that the remaining hair and dust on the cloth are cleaned up, and dehydrate it to remove the excess water in the cloth;

[0055] d. Finally, the dehydrated cloth is dried and placed in an oven at a drying temperature of 150°-200° for 60-80 seconds to complete the preliminary shaping.

[0056] S2, putting the pre-treated cloth into the processing device for further processing.

[0057] S3, antibacterial impregnation, select a suitable antibacterial agent, dissolve the antibacterial agent in water to form an antibacterial impregnation liquid, and place the antibacterial impregnation liquid in the impregnation area 20, increase the temperature of the antibacterial impregnation liquid to a required temperature, fully immerse the cloth in the antibacterial impregnation liquid, immerse for 5-10 minutes, take out the cloth, and then press the antibacterial impregnation liquid out of the cloth by rolling, and then convey the cloth to the drying area 30;

[0058] S4, drying and shaping, the antibacterial impregnation liquid remaining in the cloth is dried in the drying area 30, and after the drying is completed, the cloth is transferred to the coating area 40;

[0060] S6, pre-shrinking, after the cloth is processed by the processing device, it is finally pre-shrunk by the pre-shrinking machine.

[0061] The present invention uses the above-mentioned method steps to weave cloth through degradable fibers 18. After the cloth is pretreated, the cloth is subjected to antibacterial impregnation, and then a nano-coating 19 is coated on the surface of the cloth. When the cloth is sewn to form protective clothing, the antibacterial impregnation can increase the ability of the protective clothing to inhibit the growth of bacteria and viruses, and the nano-coating 19 can prevent liquids and dust from adhering to the surface of the protective clothing, reduce stain adhesion, and extend the service life.

[0062] like Figures 3 to 11 As shown, it is a schematic diagram of the structure of the processing device in the present invention, and the processing device includes an impregnation area 20, a drying area 30 and a coating area 40. The cloth first passes through the impregnation area 20, where the cloth is immersed in an antibacterial impregnation liquid to increase the antibacterial property of the cloth, and then passes through the drying area 30 to dry it, and finally passes through the coating area 40 to perform dust prevention treatment on the surface of the cloth.
