non-woven geotextile

Stable Fiber Needle-punched non-woven Geotextiles are made from PET/PP fibres that are tangled together by a needle-punching process. The fibres that achieve their strength by interlocking. Needle-punched non-woven Geotextiles have excellent water flow rates and are used for filtration of soil fines for drainage applications including trench drains, as a wrapping for perforated pipe, for erosion protection, and combined with three-dimensional structures to create prefabricated drains.

Short fiber geotextiles are non-woven and need punched geotextiles and belong to a kind of industrial fabrics. Short fiber geotextiles are made from high-quality polyester short fiber as raw material. Through the production process of combing, interweaving, need punching and other processing, polyester short fiber is made into geotextiles. Short fiber geotextile has excellent water permeability, filtration, durability, creep resistance and corrosion resistance, etc.

There are many types of geotextile products, including short fiber needle-punched nonwoven geotextile, long fiber needle-punched geotextile, split-film woven geotextile, and filament woven geotextile. Long fiber geotextile is a new type of construction material used in civil engineering, mainly including filtration, water filtration and reinforcement, and the raw materials include polyester, synthetic fibers of high molecular weight polymers such as polypropylene. Long fiber geotextile has a good adaptability for deformation and the ability of plane drainage, owns soft surface, good friction coefficient and can increase the adhesion ability of soil particles and other particles. It can also prevent the loss of fine particles.

Nonwoven geotextile is a kind of new material used for engineering projects, and the raw material is generally polyester synthetic fibers made from high molecular polymers, such as polypropylene. Nonwoven geotextile is divided into short-fiber or long-fiber geotextile, both of which have a good adaptability for deformation and the ability of plane drainage, owns soft surface and good friction coefficient, and can increase the adhesion ability of soil particles and other particles, and also prevent the loss of fine particles.
