1、Product introduction
Geotextile is a kind of nonwoven and industrial cloth, which is made of polyester crimped staple fiber with fiber density of 6-12 denier and length of 54-64mm.
Through the non-woven production equipment opening, combing, clutter (short fibers interwoven together), laying nets (standardized entanglement fixed), acupuncture and other production processes to make cloth. It is used in railway roadbed reinforcement, highway pavement maintenance, sports hall, dam protection, hydraulic construction isolation, tunnel, coastal beaches, reclamation, environmental protection and other projects.
2、How is staple fiber non-woven geotextile produced?
(1) Raw material unpacking: After unpacking, observe the appearance of raw materials and whether there are other debris.
(2) Raw material loosening: The role of loosening is to change the raw material from large pieces to small pieces or fiber bundles.
(3) Cotton feeding box: The fiber is fully opened and mixed into uniform 筳 cotton fed to the carder.
(4) Fiber carding: The role of the carding machine is to process the fibers through the opening process into a thin fiber net, and after laying and crossing into a net, for the acupuncture machine reinforcement.
(5) Mesh laying: The single-layer fiber net output by the carding machine needs to be repeatedly stacked through the mesh laying mechanism to achieve the product's required unit area quality and width.
(6) Acupuncture: The role of the acupuncture machine is to initially wind and finalize the fiber net formed by combing and laying the net to meet certain technological requirements, reduce the drafting of the formed fiber net as much as possible, and ensure that the direction of the fiber net of the fibril net is unchanged to achieve the best result of the product.
(7) Trimming and winding and finished product packaging.

6、Staple fiber non-woven geotextile features and applications:
(1) High strength and durability: excellent tensile strength and durability, able to resist external pressure and maintain long-term stability.
(2) Good filtration and isolation performance: allow water to pass through, while effectively preventing the flow of soil particles, helping to separate the soil and prevent erosion.
(3) Excellent drainage performance: promote water discharge, contribute to groundwater and surface water management, reduce hydrological pressure and soil infiltration.
(4) Easy to install and handle: light and flexible, easy to cut and install, to adapt to different terrain or building structures.
(5) chemical corrosion resistance: It has certain chemical stability and can resist acid and alkali corrosion, which is conducive to long-term use.
Because non-woven geotextile has the above functions, it can be widely used in railway, highway, sports stadium, dam, hydraulic construction, tunnel, along the beach, reclamation, environmental protection and other projects.
