What is the raw material of filament geotextile? What is the filament geotextile made of?

1. Filament geotextile is a kind of geosynthetics, which is called polyester filament needle-punched nonwoven geotextile. The raw material is polyester chips, without chemical additives and without heat treatment. It is a green building material.

2. The advantage of filament geotextile is that it has excellent durability and environmental resistance in the absence of illumination, and it will not degrade for hundreds of years under suitable use environment. Disadvantages: I am afraid that the ability of light to absorb ultraviolet rays is poor, and it will decompose in 2-3 years under direct sunlight. Polyester filament cloth is a kind of unclassified material. High-quality domestic chips are made into cloth by high-temperature hot melt-blown yarn at 230 degrees Celsius.

3. The filament geotextile has high cost performance and wide application range, such as the reconstruction of old roads in expressway, the reinforcement of runways in expressway and airports, and the prevention of foundation cracking. Strengthen the slope protection on both sides of expressway to prevent soil erosion. Its products are moisture-proof, waterproof and resistant to high and low temperatures.
