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 out, wash with water until neutral, and dry;

[0066] The dried cotton fiber is dipped in the zinc oxide colloid, and then gel aging and supercritical drying are carried out to obtain the flame-retardant cotton fiber loaded with nano-zinc oxide, and the loading amount of nano-zinc oxide is 14% by mass. %. Among them, the aging time of the gel is 2-10 hours, and the super-near drying conditions are 50-60°C and 20 MPa.

preparation example 2

[0067] Preparation Example 2 Flame Retardant Polyester Fiber

[0068] Preparation of liquid containing flame retardant: take nano-talc powder and evenly disperse it in the mixed liquid of amino organosilicon quaternary ammonium salt, ethanol and water. Among them, in terms of mass percentage, talc is 25%, quaternary ammonium salt is 25%, ethanol is 10%, and water is 40%.

[0069] The ordinary polyester fiber is immersed in the above-mentioned liquid containing the flame retardant, and after soaking, it is taken out and dried to obtain a composite material of nano-talc 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, under ice bath conditions, add acryloyl chloride dropwise to the nano-silica containing hydroxyl groups on the surface, and purify by centrifugation to obtain an intermediate product;

[0072] Take acrylonitrile, methyl acrylate, sodium allyl sulfonate and intermediate products as monomers (the mass ratio of materials in the monomers is 92:3.5:0.5:4), use AIBN as initiator, and use sodium thiocyanate as the The aqueous solution is used as a solvent, thiourea dioxide is used as a light coloring agent, isopropanol is used as a modifier, and an aqueous solution of sodium thiocyanate with a concentration of 55% is used as a solvent to react to obtain modified polyacrylonitrile, and the modified polyacrylonitrile is wetted. Method spinning to obtain flame retardant acrylic fiber.

[0073] Among them, the mass percentage of each feeding is:

Abstract

The invention relates to the technical field of textiles, in particular to comfortable flame-retardant cloth and a processing technique thereof. The comfortable flame-retardant cloth comprises, by mass, 40-60% of flame-retardant cotton fiber, 15-30% of flame-retardant polyester fiber, and 10-45% of flame-retardant acrylic fiber. The comfortable flame-retardant cloth has the advantages of good flame retardance, good handfeel, good comfort and the like; the three modified flame-retardant fibers developed herein help further improve the flame retardance and handfeel of the cloth herein.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a comfortable flame-retardant fabric and a processing technology thereof. Background technique [0002] In my country, textiles are the main cause of fires or the spread of fires. Therefore, the development of textile fabrics with fire-retardant and flame-retardant properties is of great significance for fire prevention and rescue. However, most of the flame-retardant textile fabrics currently developed are used for special operations. The flame-retardant effect is mainly achieved by adding flame retardants to the fabrics. However, the addition of flame retardants will affect the feel of the textile fabrics, making such Flame-retardant textile fabrics for special operations are not only expensive, but also lack comfort, so they are difficult to use in people's daily clothing and are not universal. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to pr...
