Specifications and Applications of Staple Fiber Needle Punched Geotextiles

The main specifications of non-woven geotextiles are: 100g/㎡，150g/㎡，200g/㎡，250g/㎡，300g/㎡，350g/㎡，400g/㎡，450g/㎡，500g/㎡，600g/㎡，800g/㎡

Geotextile fabrics can be classified into four categories based on their engineering application parts and functions:

◆Polypropylene staple fiber needled nonwoven geotextile for roadbed reinforcement.

It is used in subgrade engineering to enhance the strength of the foundation, reduce its deformation, and achieve the purposes of stabilizing the soil and reducing uneven settlement of the subgrade.

◆Polypropylene staple fiber needled nonwoven geotextile for subgrade drainage.

It is used in subgrade engineering and drainage engineering to protect the stability of different geotechnical structures and their functions, effectively prevent the damage of the soil body caused by the loss of soil particles, and at the same time allow water or gas to freely pass through high-strength geotextiles and be discharged, avoiding the increase in water pressure from endangering the safety of geotechnical structures, etc.

◆Polypropylene staple fiber needled nonwoven geotextile for tunnel waterproofing and drainage. It is used in the protective drainage projects of various highway tunnels, playing a role in protecting the anti-seepage membrane from damage during construction and use, and also has a certain drainage function.

◆Polypropylene short-fiber needled nonwoven geotextile for slope protection. In flexible environmental protection slope protection projects, high-strength geotextiles are used to make environmental protection ecological bags to form slope protection and can meet the requirements of environmental protection greening and plant growth. Its durability requirements are relatively high, and it should be able to ensure the effect of engineering use under alkaline conditions.
