The distinction between short geotextile and filament geotextile

Short-staple geotextile is a kind of non-woven and industrial fabric. It is made of synthetic fiber through the process of opening, combing, messing, laying, acupuncture and other production processes of non-woven production equipment. It is applied to the reinforcement of railway subgrade, the maintenance of highway pavement, the protection of sports halls, dams, the isolation of hydraulic structures, burrowing, beach coating, cofferdams, environmental protection and other projects. The filament geotextile is a polyester filament needle-punched non-woven geotextile. It is a new environmentally friendly material that does not contain chemical additives and is not heat treated. The filament geotextile has good mechanical properties, good water permeability and corrosion resistance. , anti-aging, with isolation, filtration, drainage, protection, stability, reinforcement and other functions, can adapt to the uneven base layer, can resist the damage of construction external forces, creep is small, can still maintain the original function under long-term load.

The strength of filament geotextile is the same as that of other needle-punched nonwoven fabrics under the same strength and weight; the anti-ultraviolet light has high UV resistance; the high temperature resistance is up to 230 °C, and the temperature is still high. Maintain structural integrity and original physical properties; Permeability and flat drainage geotextiles are thick and needle-punched, with good flat drainage and vertical water permeability, and can maintain this performance after many years.
