Description

Environment-friendly efficient flame-retardant non-woven fabric Technical Field The invention belongs to the technical field of non-woven fabrics, and particularly relates to an environment-friendly high-efficiency flame-retardant non-woven fabric. Background The non-woven fabric is also called non-woven fabric, needled cotton, needled non-woven fabric and the like, has the characteristics of moisture resistance, ventilation, flexibility, thinness, flame retardance, no toxicity, no smell, low price, recycling and the like, can be used in different industries such as sound insulation, heat insulation, electric heating sheets, masks, clothing, medical use, filling materials and the like, and is prepared from chemical fibers, plant fibers and the like on a wet or dry paper machine under the condition of taking water or air as a suspension medium. The existing non-woven fabrics have wide application fields, but sometimes require flame-proof and flame-retardant effects when being used in partial building or industrial scenes, and have single functionality, and the non-woven fabrics are simply compounded together to have the additional effect, but are difficult to extinguish when being burnt. Based on the above mentioned conditions, we find that the non-woven fabrics in the prior art are difficult to simultaneously avoid the problems, so we propose an environment-friendly high-school flame-retardant non-woven fabric which can remarkably improve flame retardant efficiency, has strong functionality and reduces personnel fire extinguishing difficulty Disclosure of Invention The invention aims at the existing environment-friendly high-efficiency flame-retardant non-woven fabric, and has the advantages of remarkably improving flame-retardant efficiency, being strong in functionality and reducing personnel fire-extinguishing difficulty. The technical aim of the invention is achieved by the following technical scheme that the environment-friendly high-efficiency flame-retardant non-woven fabric comprises an inner layer, wherein an intermediate layer is arranged on the outer side of the inner layer, an outer layer is arranged on the outer side of the intermediate layer, a filler cylinder is arranged on the inner side of the intermediate layer, flame-retardant filler is filled in the filler cylinder, and the intermediate layer is in wave-shaped arrangement and wraps the filler cylinder; The outer layer comprises a strength layer, wherein a matching layer is arranged on the inner side of the strength layer, an elastic layer is arranged on the inner side of the matching layer, and a flame-retardant layer is arranged on the inner side of the elastic layer; The inner layer comprises an antistatic layer, the inner side of the antistatic layer is provided with a breathable layer, and the inner side of the breathable layer is provided with a tearing-resistant layer.
