Abstract

The invention provides a multi-layer non-woven geotextile and a preparation method thereof. The multi-layer non-woven geotextile comprises a base cloth layer, the base cloth layer is formed by weavingwarp and weft yarns in a crossed mode, an edge covering layer is sewn on the outer side of the base cloth layer through nylon threads, a reinforcing layer is sewn at the bottom of the base cloth layer, and the reinforcing layer comprises a cotton-linen textile layer, a woven silk screen layer, a wear-resistant coating layer, polyester yarns, high-strength fiber yarns and aramid fiber yarns. According to the invention, the cotton-linen textile layer, the woven silk screen layer and the wear-resistant coating layer are matched, the overall reinforcing effect of the base cloth layer is enhanced,the extrusion pressure at the bottom of the base cloth layer can be effectively released, the base cloth layer is prevented from being torn and damaged by sharp stones and convex blocks, and the overall material strength of the warp yarns and the weft yarns is enhanced through cooperation of the polyester yarns, the high-strength fiber yarns and the aramid yarns, so that the overall tearing strength of the base cloth layer is directly enhanced, the stress buffer effect of the base cloth layer is further enhanced, and the overall service life of the base cloth layer is prolonged.

Description

technical field [0001] The invention relates to the field of non-woven geotextiles, in particular to a preparation method of multi-layer non-woven geotextiles. Background technique [0002] Non-woven geotextiles (polyester geotextiles, non-woven geotextiles), also known as geotextiles, are water-permeable geosynthetic materials made of synthetic fibers through needle punching or weaving. The finished product is cloth-like, with a general width of 4-6 meters. , the length is 50-100m. [0003] When users use it to strengthen the weak foundation, they need to use non-woven geotextiles for laying protection. However, during the use of traditional non-woven geotextiles, sharp stones and bumps are easily distributed on the surface of the roadbed, which is easy to cause no The woven geotextile is torn and damaged by force, thereby reducing the tear strength of the non-woven geotextile and shortening the normal service life of the non-woven geotextile. [0004] Therefore, it is ne...
