2021 China New Design Staple Fibers Geotextiles - staple fibers needle punched geotextile – Taixi
2021 China New Design Staple Fibers Geotextiles - staple fibers needle punched geotextile – Taixi Detail:
Product Description
The short fiber geotextile has good water conductivity, and the short fiber needle-punched non-woven geotextile can create a safe channel for drainage pipes in the internal structure of the soil, and discharge excess liquid and waste gas in the soil structure; the use of geotextiles to improve the soil quality. Compressive strength and anti-deformation level, improve the stability of building structure, and improve soil quality; Efficiently diffuse, transmit or dissolve concentrated stress to avoid soil damage due to external forces; Avoid upper and lower layers of sand, gravel, soil It is doped between the body and cement; the mesh tissue formed by the amorphous connective tissue has strain and autonomous movement, so the pores are not easy to block; it has high water permeability and can still maintain good under the pressure of soil and water Water permeability; with polypropylene cloth or polyester and other chemical fibers as the main raw materials, it is corrosion-resistant, non-erosive, non-insect-resistant, and has anti-oxidation specifications and models: the width can reach 6 meters. It is the widest commodity in China, the utilization factor quality: 100-600g/㎡;
Staple fibers needle punched non-woven geotextile is made of PP or PET staple fibers and processed by on carding cross-laying equipment and needle punched equipment. It has the functions of isolation, filtration, drainage, reinforcement, protection and maintenance.
