What are the general classification of geotextiles


What are the general classification of geotextiles? Geotextile is a single water-permeable material made from polymer as raw material, through non-woven process, weaving process, weaving process and wet-laid process. It is widely used in road, railway, water conservancy and water transport. Infrastructure, airport, environmental protection and other infrastructure construction, in the project to play the role of filtration, drainage, protection, isolation and crack prevention. What are the general classifications of geotextiles? 


What are the general classification of geotextiles? Geotextiles are classified into woven geotextiles (with spinning), non-woven geotextiles (non-woven), composite geotextiles, and wet-laid geotextiles according to different manufacturing methods. Among them: 


1. Weaving geotextile (with spinning) is made of synthetic fiber filament (polypropylene, polyester, nylon, vinylon, ethylene, etc.) or plastic flat wire, plastic split film wire arranged in a certain direction of woven geotextile; 


2. Non-woven geotextile (non-woven) fabric made of short fibers or filaments arranged in a random arrangement or orientation, mechanically bonded, heat-bonded or viscous; 


3, wet-laid geotextile The chopped polyester fiber and the glass fiber are produced by dispersing the raw material in water, and are produced by a process of copying, dehydrating, sizing, drying, etc.;


Main products: geotextile, geomembrane, filament geotextile, short geotextile, woven geotextile, composite geotextile, composite geomembrane, geogrid,

geotextile


4. Composite geotextile: a filament woven geotextile or a split-filament woven geotextile (woven geotextile) made of polymer as raw material and a stapled needle-punched non-woven geotextile Geotextile. It has the functions of protection and reinforcement, and is mainly used in engineering fields such as reinforcement of soft soil foundation and reinforcement of embankment foundation. 

According to the product structure, it is divided into two-layer composite and three-layer composite. Geotextiles can be divided into 


1. Polyester staple fiber needle-punched nonwoven geotextiles according to different raw materials; 


2. Polypropylene staple fiber needle-punched nonwoven geotextile


3. Polyester filament spunbonded needle-punched nonwoven geotextile; 


4, polypropylene filament woven geotextile; 


5, polyester filament woven geotextile; 


6, basalt fiber woven geotextile; 


7, polypropylene split film woven geotextile; 


8, plastic flat woven geotextile; 


9. Polyester glass fiber wet non-woven geotextile.



Main products: geotextile, geomembrane, filament geotextile, short geotextile, woven geotextile, composite geotextile, composite geomembrane, geogrid,

nonwovengeotextile


Geotextiles can be divided into drainage anti-filter geotextiles, wrapped geotextiles, isolated geotextiles and reinforced geotextiles according to different functions.
