Properties of Woven Geotextiles

There are many kinds of geotextiles, which can be divided into knitted geotextiles, non-woven geotextiles and woven geotextiles according to the production method. Among them, the woven geotextile is a fabric woven by two groups of filaments or flat strips. ) and woven impermeable cloth. The development of woven geotextiles in my country is more than ten years later than that of non-woven geotextiles, and the current production technology is still in its infancy. The raw materials of woven geotextiles are mainly polypropylene flat woven fabrics, supplemented by high-strength nylon woven fabrics, with a width of more than 3800mm and a specification of 120-150g/m2. Choose 200-500g/m2 fabric.

Characteristics of woven geotextiles

Woven geotextiles have advantages in high-strength applications such as reinforcement, reinforcement, and erosion resistance. It is mainly used for the treatment of diseased sections of highways and railways, the improvement of soft soil sections, the reinforcement of slope protection in river embankments, dams, seaports, etc., as well as the construction of airport runways and artificial islands, etc., and its application range is quite extensive. The product has the following characteristics.

(1) The tensile strength and modulus of the woven geotextile are large, and the elongation at break is small, and it has a better stress-strain relationship.

(2) The warp and weft yarns in the woven geotextile are squeezed against each other, preventing the deformation of the fabric when it is subjected to external forces, so the structure of the woven geotextile is generally relatively stable.
