Details of woven fabric 1:

The woven fabric is made of polypropylene and polypropylene fiber flat yarn. It is composed of two groups of parallel yarns (the shape of which is flat thread). One group is called warp yarn along the longitudinal direction of the loom, and the other group is called weft yarn. The warp and weft are interwoven into cloth shape by different knitting equipment and technology, which can be woven into different thickness and density according to different application range. Generally, woven geotextile is thin and has strong tensile strength (longitude is greater than latitude) in both vertical and horizontal directions, and has good stability. It can maintain sufficient strength and elongation under dry and wet conditions. Woven fabrics are also known as textile geotextiles and woven geotextiles.

Product performance:

1. Reinforcement: used in highway, railway, airport, stone dam, breakwater, retaining wall backfill, side slope and other rock engineering, to disperse soil stress, increase soil modulus, limit soil slip and improve stability.

2. Protection function: prevent the bank from being scoured by wind, wave, tide and rain, and be used for bank protection, slope protection, bottom protection and soil erosion prevention.

3. Filter action: it is used for the filter layer of dike, dam, river and coastal stone, soil slope and retaining wall to prevent sand particles from passing through, while allowing water or air to pass freely.
