nonwoven geotextile

Introduction

      Non woven geotextile is a kind of new building materials,the raw material is polyester, polypropylene, acrylic, nylon and other synthetic polymers. According to the manufacturing methods are divided into: woven geotextile and non-woven geotextile two types.General engineering mainly use the non-woven geotextile .  

     Geotextile is impervious, filter, drainage, isolation, reinforcement and protection, sealing and other functions, it compared with the conventional masonry and concrete materials anti-seepage effect, low investment, simple construction technology, short time limit, good anti-seepage effect, channel high effective utilization coefficient, etc 

Characteristics
     1. High strength, due to the use of plastic fiber, in the wet state can keep sufficient strength and elongation.
     2. Corrosion resistance, can in different ph value of soil and water corrosion for long.
     3. Good permeability Have a gap between the fibre, therefore has the good porous.
     4. The microbial resistance is good On microbe, bug eat by moth.
     5. Construction is convenient, because the material is qualitative light, soft, transporting, laying, construction is   

         convenient.

     6. Complete specifications, width can be up to 9 m.Is the present domestic the most wide products, mass per unit 

         area: 100-1000 g /sq.m.

Role Play
1. Isolation 

     Use of polyester staple fiber nonwoven fabric with different physical properties (particle size, distribution, consistency and density, etc.) of the building materials (such as soil and sand, soil and concrete, etc.) in isolation.Make no loss between two or more materials, not mixed, maintains the whole structure and function of material, to reinforce structure load bearing capacity. 

2. Filteration
     When water flows into coarse material composed of fine soil soil layer, the use of polyester staple fiber geotextile acupuncture good air permeability and water permeability, make the water flow through, and effectively current-carrying soil particles, sand, small stones, etc., to maintain the stability of soil and water conservation project. 

3. Drainage
     Polyester staple fiber geotextile acupuncture has good conductivity performance, it can be formed within soil drainage channel, excess liquid and gas discharge of the soil structure.
