Problems solved by technology

[0002] At present, there are various kinds of woven geotextiles on the market, but most of them have a relatively single structure layer, which cannot meet the requirements of long-term continuous use. In the actual use process, many problems are prone to occur.
The geotextiles currently used have low strength, low elongation, poor acid and alkali corrosion resistance, and cannot meet the requirements of sea reclamation, land reclamation, siltation promotion, port, wharf, airport, dock, waterway management, etc. Moreover, the production process of ordinary geotextiles is relatively general, and the quality of the products produced is relatively average. There is no needling structure level, and the overall instability. Therefore, ordinary geotextiles can no longer meet the actual use needs.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 Shown, a kind of high-strength polypropylene geotextile of the present invention, it comprises singeing layer 1, is provided with non-woven fabric layer 2 under described singeing layer 1, is provided with under described non-woven fabric layer 2 Water-repellent layer 3, below described water-repellent layer 3 is provided with ironing layer 4, and they are closely combined with each other; The width is between 4.2-8m; the non-woven fabric layer 2 is a needle-punched non-woven fabric layer. In the present invention, after scalding treatment, the water-repellent layer is firmly fixed on the surface layer of the non-woven fabric, and forms a smooth surface, so that it can be better combined with polyurethane glue during the construction of the high-speed rail sliding layer in the later stage. The invention shrinks the fiber fleece...

Abstract

The invention relates to high-intensity polypropylene geotechnical cloth which comprises a singeing layer, wherein a non-woven cloth layer is arranged on the lower surface of the singeing layer; a water-repellency layer is arranged on the lower surface of the non-woven cloth layer; a finishing layer is arranged on the lower surface of the water-repellency layer; the singeing layer, the non-woven cloth layer, the water-repellency layer and the finishing layer are tightly combined. The high-intensity polypropylene geotechnical cloth is high in quality, long in service life, higher in intensity, higher in ductility, acid-proof, alkaline-proof and anti-corrosion.

Description

technical field [0001] The invention relates to a geotextile, in particular to a polypropylene geotextile. Background technique [0002] At present, there are various kinds of woven geotextiles on the market, but most of them have a relatively single structure layer, which cannot meet the requirements of long-term continuous use. In the actual use process, many problems are prone to occur. The geotextiles currently used have low strength, low elongation, poor acid and alkali corrosion resistance, and cannot meet the requirements of sea reclamation, land reclamation, siltation promotion, port, wharf, airport, dock, waterway management and other projects. Moreover, the production process of ordinary geotextiles is relatively general, and the quality of the products produced is relatively average. There is no needling structure level, and the overall instability. Therefore, ordinary geotextiles can no longer meet the actual use needs. Contents of the invention [0003] Purpo...
