Abstract: the invention relates to a flame-retardant fabric, in particular to a flame-retardant high elastic fiber non-woven fabric and a manufacturing method thereof. At present, a kind of flame-retardant single and porous hollow three-dimensional crimped polyester staple fiber with high phosphorus content, which has achieved industrial production, has good flame-retardant effect and is widely used. However, the condensation reaction between hollow three-dimensional crimped polyester staple fiber and flame retardant meets the experiments of large and full-size samples, which affects the resilience of the original hollow three-dimensional crimped polyester staple fiber. The invention provides a flame-retardant high elastic fiber non-woven fabric and a manufacturing method thereof, which is characterized in that it includes flame-retardant single and porous (single hole, four hole, seven hole and nine hole) hollow three-dimensional crimped polyester staple fiber, high elastic cotton and tensile cotton with high phosphorus content, wherein the weight percentage of flame-retardant single and porous (single hole, four hole, seven hole and nine hole) hollow three-dimensional crimped polyester staple fiber with high phosphorus content is 75% - 65%, The weight percentage of high elastic cotton is 15% - 5%, and the weight percentage of tensile cotton is 25% - 15%; The above three mixed fibers are combined into non-woven fabrics through interpenetration, which not only retains the original flame retardant performance, but also has high elastic performance

sovereignty item: a kind of flame-retardant high elastic fiber non-woven fabric, which is characterized by: including flame-retardant single and porous (single hole, four hole, seven hole, nine hole) hollow three-dimensional crimped polyester staple fiber, high elastic cotton, tensile cotton with high phosphorus content, in which the weight percentage of flame-retardant single and multi hole (single hole, four hole, seven hole, nine hole) hollow three-dimensional crimped polyester staple fiber with high phosphorus content is 75% - 65%, The weight percentage of high elastic cotton is 15% "we are cooperating with our partners and customers to ~ 5%, and the weight percentage of tensile cotton is 25% - 15%. The above three kinds of mixed fibers are combined into non-woven fabrics through mutual wear.
