Example Embodiment

[0032] The invention relates to a method for preparing a nano-breathing multifunctional fabric. It uses a polyester/nylon fiber base fabric as the cloth surface, and is functionally obtained through nano-material pre-treatment, nano-microporous coating reaction and nano-material post-treatment For the 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-double phobic mother liquor with water- and oil-proof functions, stir for 5-10 minutes to prepare solution A, ready for use,
[0035] b. Dip the polyester/nylon base cloth into solution A at 4kg/cm 2 The pressure is squeezed by the rollers, and the rolling residue is controlled at 60-70%. It is dried in an oven at a temperature of 130-150℃ and a speed of 25-30m/min, and cooled to obtain cloth surface B.
[0036] Step 2: Nano-microporous coating reaction
[0037] a. Add 500kg of solvent dimethylformamide into the reactor, add 50kg of nanometer anti-far infrared masterbatch 2-hydroxy-4-n-octyloxybenzophenone while stirring, stir at high speed for 10 minutes, add colorant and stir 2 Then add 50kg of 2-hydroxy-4-n-octyloxybenzophenone nanometer anti-far-infrared masterbatch, and stir at high speed for 10 minutes; add 500kg of polyurethane and stir for 10 minutes, then add the anti-fat Diluent fluorine compound high fluorinated butyl 5kg, nano-microporous hair penetrating agent alkylated diphenylamine 20kg, cell adjustment assistant coconut oil acid diethanolamide 40kg, each reactant is added while stirring separately, after adding After stirring and reacting for 5 minutes, another reactant can be added, stirring at high speed for 40 minutes, vacuuming to -0.8Mpa, and maintaining pressure and stirring for 1 hour, filtering and standing still to make nano coating material C;
[0038] b. Coat the nano-coating material C on the surface of cloth B, and then enter the solvent dimethylformamide aqueous solution to react, the solvent dimethylformamide concentration is controlled at 3 to 5%, and the temperature is controlled at 30±2℃; After 6 minutes of reaction, squeeze to dry, enter 50-60 ℃ clean water for reaction; after 6 minutes of reaction and 4 to 5 times of squeezing, squeeze dry to 40-60%, enter the oven for drying, at a temperature of 120-140 ℃ Dry for 1.5 to 2 minutes to obtain a semi-finished fabric D.
[0039] Step 3: Post-processing of nanomaterials
[0040] a, take H 2 O 200kg into the reaction kettle, while stirring, add nano-material waterproof and oil repellent 2,5-di-tert-butyl hydroquinone 10kg, fatty amide and modified polysiloxane compound 1.6kg, double ( 2,2,6,6-Tetramethylpiperidinyl) sebacate 5kg, nano silver ion antibacterial agent 10kg, cell finishing agent azodicarbonamide 0.2kg, stir for 5-10 minutes to obtain solution E, where The weight ratio of the fatty amide to the modified polysiloxane compound is 1:0.8-1.2,
[0041] b. The semi-finished fabric D is completely reacted in the solution E, squeezed by a roller, the remaining 70-80% is rolled, and dried at 150-170°C for 2 minutes to obtain the finished fabric.
