Abstract

The invention belongs to the technical field of nonwoven fabrics, and particularly relates to a polypropylene nonwoven fabric modification material. The polypropylene nonwoven fabric modification material is prepared from the following components: polypropylene, lignin, dimethoxymethylphenylsilane, epoxy resin, triethyl citrate, epoxidized soybean oil, konjac glucomannan, polyvinyl alcohol, glass fibers and acetylated wood meal. The polypropylene nonwoven fabric modification material prepared by the method of the invention is light in specific weight, high in flexibility, high in tensile strength, high in breaking force, high in impact resistance, good in ultraviolet aging resistance, and simple in preparation method; and a nonwoven fabric prepared by the polypropylene nonwoven fabric modification material prepared by the invention is high in strength, good in wear resistance, capable of adsorbing harmful gas and peculiar smell, good in mold resistance, and high in dyeing fastness, and the light fastness can reach grade 6 or above.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabrics, and in particular relates to a modified polypropylene nonwoven fabric material. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. 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. At present, although non-woven fabrics have many excellent characteristics, compared with conventional fabrics, they have larger specific gravity, weak toughness, low breaking strength, weak tensile ability, low impact resistance, and low color fastness. Limit its application in industry and agriculture. Contents of the invention [0003] The object of the present invention is to provide a polypropylene non-...
