Abstract

The invention relates to a multifunctional non-woven fabric. The multifunctional non-woven fabric comprises a middle layer, an upper surface layer and a lower surface layer, wherein the upper surface layer and the lower surface layer are located on the two sides of the middle layer respectively. The middle layer is prepared from, by weight, 35-55 parts of modified bamboo charcoal fibers, 15-20 parts of jute fibers, 10-15 parts of coconut fibers, 3-5 parts of modified nano-pyrophyllite, 15-25 parts of algae extract and 3-5 parts of chitin fibers. The composite non-woven fabric can be normally produced completely according to an original production technology; the non-woven fabric is environmentally friendly, degradable, good in filtering performance, spinnability, coloring performance and softness, free of size dripping, uniform in lapping, normal in gram weight and high in tensile strength; the anti-bacterial, flame-retardant and waterproof effects are good; toxicity and irritation are avoided, strength is non-directional, and the longitudinal strength and the transverse strength are approximate.

Description

technical field [0001] The invention relates to a nonwoven fabric, in particular to a multifunctional nonwoven fabric which is antibacterial, environmentally friendly, degradable, 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 s...
