Abstract
The filament polypropylene composite water-guiding geotextile is formed by connecting an upper polyester filament layer with a lower polypropylene staple layer through a plurality of knitting threads, wherein the knitting threads are arranged on the surface of the geotextile body. According to the utility model, the polyester filament layer and the polypropylene staple fiber layer are connected up and down in a composite way, the polyester filament layer endows the geotextile with higher strength, the polypropylene staple fiber endows the geotextile with better acid and alkali resistance, meanwhile, the cost of the polypropylene staple fiber is low, the production cost of the composite geotextile can be effectively reduced, and in addition, the water diversion grooves formed on the surface of the cloth body by the woven wires can guide and discharge rainwater on the surface of the geotextile, so that the formation of accumulated water is prevented.
Description
Technical Field
The utility model relates to the technical field of geotextile production, in particular to filament polypropylene composite water-guiding geotextile.
Background
Geotextile, also called geotextile, is a water permeable geosynthetic material formed by needling or braiding synthetic fibers, and the finished product is cloth-like, and has a general width of 4-6 m and a length of 50-100 m. Geotextiles are classified into woven geotextiles and non-woven geotextiles. Most geotextile in the market at present is polyester filament spun-bonded needle-punched geotextile, polyester filament strength is high, but polyester material chemical stability is poor, acid and alkali resistance is not achieved, the geotextile can be broken after long-time use, influence is easily caused on engineering, polypropylene filament geotextile is adopted to replace polyester filament geotextile in the industry in order to solve the problem that the polyester filament geotextile is poor in corrosion resistance, although the polypropylene filament geotextile is acid and alkali resistant, production cost is high, geotextile cost is high, market popularization of geotextile is affected, corrosion resistance published by the existing graph is improved, production cost of geotextile can not be increased, and the geotextile is the subject of important research in the industry.
Disclosure of Invention
The utility model provides a filament polypropylene composite water-guiding geotextile, which aims to solve the problems that the polyester filament geotextile in the prior art is not corrosion-resistant and the cost of the polypropylene filament geotextile is high.
The technical scheme adopted for solving the technical problems is as follows:
the composite water-guiding geotextile is formed by connecting an upper polyester filament layer with a lower polypropylene staple layer through a plurality of knitting threads, wherein the knitting threads are arranged on the surface of the geotextile body, and a plurality of water-guiding grooves are formed in the surface of the geotextile body.
According to the utility model, the polyester filament layer and the polypropylene staple fiber layer are connected up and down in a composite way, the polyester filament layer endows the geotextile with higher strength, the polypropylene staple fiber endows the geotextile with better acid and alkali resistance, meanwhile, the cost of the polypropylene staple fiber is low, the production cost of the composite geotextile can be effectively reduced, and in addition, the water diversion grooves formed on the surface of the cloth body by the woven wires can guide and discharge rainwater on the surface of the geotextile, so that the formation of accumulated water is prevented.
Drawings
The utility model will be further described with reference to the drawings and examples.
Fig. 1 is a schematic structural view of the geotextile of the present utility model.
In the figure, a polyester filament layer 1, a polypropylene staple fiber layer 2 and a knitting yarn 3 are adopted.
Detailed Description
As shown in the figure, the filament polypropylene composite water-guiding geotextile is formed by connecting an upper polyester filament layer 1 with a lower polypropylene staple layer 2 through a plurality of knitting threads 3, wherein the knitting threads 3 are arranged on the surface of the geotextile body.
According to the utility model, the polyester filament layer and the polypropylene staple fiber layer are connected up and down in a composite way, the polyester filament layer endows the geotextile with higher strength, the polypropylene staple fiber endows the geotextile with better acid and alkali resistance, meanwhile, the cost of the polypropylene staple fiber is low, the production cost of the composite geotextile can be effectively reduced, and in addition, the water diversion grooves formed on the surface of the cloth body by the woven wires can guide and discharge rainwater on the surface of the geotextile, so that the formation of accumulated water is prevented.
