Embodiment Construction
[0032] The invention relates to a preparation method of a nano-breathable multi-functional fabric, which uses polyester / nylon fiber base cloth as the cloth surface, and undergoes nano-material pretreatment, nano-micropore coating reaction and nano-material post-treatment. Fabric, the specific process steps are as follows:
[0033] Step 1. Pretreatment of nanomaterials
[0034] a. Add H to the reactor 2 O 200kg, 6kg of nano-fluorine compound nano amphiphobic mother liquor with waterproof and oil-proof functions, stirred for 5-10 minutes, made solution A, and set aside,
[0035] b. Immerse the polyester / nylon base cloth in solution A at a rate of 4kg / cm 2 The pressure is extruded by rollers, and the excess is controlled at 60-70%. It is dried in an oven at a temperature of 130-150°C and a speed of 25-30m / min, and the cloth surface B is obtained after cooling.
[0036] Step 2. Nanoporous coating reaction
[0037] a, 500kg of solvent dimethylformamide is added to the reaction ...
