Abstract

The invention relates to a flame-retardant fiber non-woven fabric. The flame-retardant fiber non-woven fabric comprises a middle layer, and an upper surface layer and a lower surface layer which are located at two sides of the middle layer, wherein the middle layer is prepared from the following raw materials in parts by weight: 35 to 55 parts of modified cocoanut husk fiber, 5 to 8 parts of chrysotile, 10 to 15 parts of flame-retardant fiber, 3 to 5 parts of modified nano-sized pyrophyllite, 15 to 25 parts of an algae extract and 3 to 5 parts of zinc borate. The composite material non-woven fabric provided by the invention has the following advantages: normal production can be totally realized according to an original production process; and the non-woven fabric has good filtering performance and spinnability, no pulp dripping, good coloring performance, uniform lapping, normal gram weight, high tensile strength, good softening property, bacterium resistance, flame retardancy, good waterproof effect, no toxicity, no stimulation, non-directional strength, and similar vertical and horizontal strength.

Description

technical field [0001] The invention relates to a non-woven fabric, in particular to a flame-retardant fiber non-woven fabric which is antibacterial, environmentally friendly, and has good flame-retardant and waterproof effects. Background technique [0002] Non-woven fabrics (English name: Non Wowen), also known as non-woven fabrics, are composed of directional or random fibers, and are moisture-proof, breathable, flexible, light in weight, non-combustible, non-toxic, non-irritating, rich in color, and low in price. Low cost, recyclable and so on. For example, polypropylene pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because it has the appearance and certain properties of cloth. [0003] Non-woven fabrics are widely used in artificial leather, furniture, chemicals, printing, decoration, packaging, automobiles, building materials servi...
