S2: Make flame-retardant fabrics by placing warp Nomex fiber, modified glass fiber and weft polyimide 2080 fiber in a loom for weaving to obtain a heat-insulating flame-retardant fabric;

S3: Apply the material and apply the flame-retardant compound to one side of the flame-retardant fabric woven in S2 to obtain a new heat-insulating flame-retardant fabric;

S4: Make breathable fabrics by placing warp silk fibers, antibacterial fibers and weft cotton fibers in a loom for weaving to obtain silk antibacterial breathable fabrics;

S5: Make a base fabric. Put the warp modified ramie fiber and weft polyester fiber into a loom for weaving to obtain a base fabric. This invention uses modified ramie fiber with good air permeability as the main fiber to ensure the air permeability of the base fabric. For heat dissipation performance, the shape retention of the base fabric is improved by adding polyester fiber, and the ramie fiber is modified to improve its elasticity, cohesion and spinnability;

S6: Base fabric treatment. The base fabric in S6 is bleached and dyed, wrinkled, and dried in a dryer to obtain the treated base fabric;

S7: Apply adhesive, place the heat-insulating and flame-retardant fabric in S3 and the base fabric in S6 in the rubber roller, and apply the adhesive on the surface of the heat-insulating and flame-retardant fabric and base fabric;

S8: Bonding, with heat-insulating and flame-retardant fabric as the surface layer, silk antibacterial and breathable fabric as the middle layer, and base fabric as the bottom layer. Use an embossing machine to heat-press to obtain flame-retardant and breathable fabric. The surface layer of heat-insulating and flame-retardant fabric and smearing The flame-retardant compound on its surface forms a double flame-retardant protection mechanism, which greatly increases the flame-retardant performance of the fabric. At the same time, the silk antibacterial and breathable fabric is woven from natural cocoon silk and has good breathability, which makes it have good flame retardancy. performance and breathability;

S9: Rolling, the heat-pressed flame-retardant breathable fabric in S8 is air-cooled, trimmed, and rolled.
