Examples
preparation example 1
[0064] Preparation Example 1 Flame Retardant Cotton Fiber
[0065] Use potassium hydroxide with a mass fraction of 9% and urea with a mass fraction of 9% as a mixed solution, soak ordinary cotton fibers for 6 hours, take them out, wash with water until neutral, and dry;
[0066] The dried cotton fiber is dipped in zinc oxide colloid, then subjected to gel aging and supercritical drying to obtain flame-retardant cotton fiber loaded with nano-zinc oxide, and in terms of mass percentage, the loading amount of nano-zinc oxide is 14 %. Among them, the aging time of the gel is 2-10 hours, and the conditions for ultra-close drying are 50-60°C and 20 MPa.
preparation example 2
[0067] Preparation example two flame retardant polyester fiber
[0068] Preparation of liquid containing flame retardant: take nano talc powder and disperse evenly in the mixed liquid of aminoorganosilicon quaternary ammonium salt, ethanol and water. Wherein, in terms of mass percentage, talcum powder is 25%, quaternary ammonium salt is 25%, ethanol is 10%, and water is 40%.
[0069] Immerse ordinary polyester fibers in the above-mentioned flame retardant-containing liquid, take them out after soaking, and dry to obtain a composite material of nano talc powder and polyester, which is a flame-retardant polyester fiber.
preparation example 3
[0070] Preparation Example 3 Flame-retardant acrylic fiber
[0071] Using anhydrous DMF as a solvent, add acryloyl chloride dropwise to nano-silica containing hydroxyl groups on the surface under ice bath conditions, and centrifugally purify to obtain an intermediate product;
[0072] Acrylonitrile, methyl acrylate, sodium allyl sulfonate, and intermediate products are used as monomers (the mass ratio of materials in monomers is 92:3.5:0.5:4), AIBN is used as an initiator, and sodium thiocyanate is used The aqueous solution is used as a solvent, thiourea dioxide is used as a light coloring agent, isopropanol is used as a regulator, and a 55% sodium thiocyanate aqueous solution is used as a solvent to react to obtain modified polyacrylonitrile, and the modified polyacrylonitrile is wetted. Spinning method to obtain flame retardant acrylic fiber.
[0073] Wherein, the mass percent of each feed intake is:
