Embodiment 1

[0021] A composite material non-woven fabric, comprising a middle layer, an upper surface layer and a lower surface layer respectively located on both sides of the middle layer, the upper surface layer is a polyethylene foamed cotton layer, and the lower surface layer is a skin-core composite fiber layer. The skin-core composite fiber layer includes nano-scale vanadium dioxide, and the content of nano-scale vanadium dioxide is 3% of the skin-core composite fiber layer; the intermediate layer is prepared from the following raw materials by weight: 35 parts of bamboo charcoal fiber, 10 10 parts corn fiber, 10 parts sisal fiber, 3 parts modified nano dickite, 15 parts algae extract and 3 parts witch hazel extract. The upper surface layer accounts for 40% of the total mass of the nonwoven fabric, the middle layer accounts for 30% of the total mass of the nonwoven fabric, and the lower surface layer accounts for 30% of the total mass of the nonwoven fabric.

Abstract

The invention relates to composite material non-woven fabrics. The non-woven fabrics comprise an interface layer, an upper surface layer placed on one side of the interface layer, and a lower surface layer placed on the other side of the interface layer. The interface layer is prepared from the following raw materials: by weight, 35-55 parts of bamboo-carbon fiber, 10-15 parts of corn fiber, 10-15 parts of sisal fiber, 3-5 parts of modified nano-dickite, 15-25 parts of algae extract, and 3-6 parts of witch hazel extract. The composite material non-woven fabrics prepared by the invention can be normally prepared according to the original production technology, has good filtration property, spinnability, pigmenting property, softening property, antimicrobial effect, flame retardant effect, and waterproof effect, does not drop the slurry, has uniform laying net, has normal gram weight and high tensile strength, is non-toxic and non-stimulating, has non-directional strength, and has similar strength in longitudinal and lateral directions.

Description

technical field [0001] The invention relates to a non-woven fabric, in particular to a composite material 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 services...
