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:

Abstract

The invention relates to the technical field of textile products, in particular to a comfortable flame-retardant fabric and a processing technology thereof. The comfortable flame-retardant fabric is prepared from the following raw materials in percentage by mass: 40 to 60 percent of flame-retardant cotton fibers, 15 to 30 percent of flame-retardant polyester fibers and 10 to 45 percent of flame-retardant acrylic fibers. The flame-retardant fabric has the characteristics of flame retardance, soft hand feel, more comfortability and the like; moreover, the developed three modified flame-retardantfibers are beneficial to further improvement of the flame retardance performance and the comfort hand feel of the fabrics.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a comfortable flame-retardant cloth and a processing technology thereof. Background technique [0002] In my country, textiles are the main cause of fires or the spread of fires, so the development of textile fabrics with fire and flame retardant properties is of great significance for fire prevention and rescue. However, most of the currently developed flame-retardant textile fabrics are used for special operations, and 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 textile fabrics, making such fabrics Flame-retardant textile fabrics for special operations are not only expensive, but also lack comfort. They are difficult to be used in people's daily clothing and are not universal. Contents of the invention [0003] The purpose of the present invention is to provide a c...
