It is difficult for consumers who don't know much about geotextile products to understand the difference between woven geotextile and nonwoven geotextile.

The biggest difference between nonwoven geotextile and woven geotextile lies in the different production process. Nonwoven geotextile is woven with filament and short fiber through needle punching and other production processes with the help of mechanical equipment. Geotextile is composed of at least two groups of silk threads in the direction of longitude and latitude.

The difference of production technology makes nonwoven geotextile and spinning geotextile show anisotropic influence on product characteristics. Although nonwoven geotextile has good deformation effect, its deformation effect is not as good as woven geotextile. Geotextile has a considerable tensile strength effect on Chinese fir in the horizontal direction, which is more practical in the reinforcement effect.

The filtration and drainage of geotextile need to have permeability, so it must have good permeability. At present, most of the geotextile materials are polymer materials, among which polypropylene (including fiber) is the most widely used material, accounting for about 50% of the total geotextile, and the United States has accounted for more than 80%. Polyester raw materials (including polyester) account for 15% - 30%, ranking the second place, and are widely used in Japan. Polyethylene and polyamide fibers are less used, and vinylon is also used in China. Polypropylene raw materials are mostly used, and the price is an important factor, but polypropylene mainly has excellent acid and alkali resistance, corrosion resistance, mildew resistance, no bacterial erosion; it has good core pulling effect and water permeability. Its mechanical properties are also very good, especially in recent years, China has developed high-strength polypropylene filament, the strength can reach 8g / D, the production of high-strength polypropylene woven geotextile and bag fabric is very suitable.
