摘要： A flame retardant fabric is directly woven from flame retardant viscose fiber added with inorganic silicon for covering the outside of flammable articles, wherein the flame retardant viscose fiber having denier, strength and flame retardant effect which use silicic acid as the flame retardant, and coating a layer of organic material, melamine flame retardant resin on the surface of silicic acid, and then preparing the flame retardant viscose fiber into an nano-sized particles. The flame retardant fabric has a fineness of 1.11 to 2.78 dtex, and a strength of ≥2.0 cN/dtex, which meets the production requirements of spinning, and does not need to be blended with other high-strength fibers when spinning, and the woven fabric from the flame retardant viscose fiber does not need to be flame retardant, so that the flame retardant fabric has a good flame retardant effect and saves costs through simply the production process.

摘要： The flame retardant yarn of the present invention is made by blending flame retardant viscose fiber and at least one high tenacity flame retarding fiber, the at least one high tenacity flame retarding fiber is flame retardant polyester or flame retardant finishing viscose fiber, wherein the flame retardant viscose fiber is 40˜90% by weight of the flame retardant yarn. The flame retardant yarn takes advantage of the superior flame retardance of the flame retardant viscose fiber, and takes the flame retardant viscose fiber to blend with other good tenacity and spinnability fiber by adjusting amount of raw materials in reasonable balance and avoiding disadvantages of the raw materials to optimize advantages of the flame retardant viscose fiber such as flame retardancy and tenacity so as to provide the flame retardant viscose fiber with high flame retardancy, long lasting flame retardancy effect, strength and elongation performance and good abrasion resistance. Fabric made by the flame retardant yarn not only has good flame retardancy, but also has good elasticity due to high tenacity of the flame retardant yarn.
