construction material geotextile fabrics
Introduction:
Short fiber kniitting geotextile takes the polypropylene fiber or polyester fiber short fiber as the primary material,after blooms the
pine,to comb,disorderly,craft productions and so on shop net,acupuncture to become.
Feature:
1.net holes are easy for blockage,since net structure formed by indefinite fiber has variable and motility.
2.it has high permeation and can keep good permeation under the pressure of the earthwork.
3.it has corrosion resistance,uses chemical fiber such aspolypropylene or daron as raw material,has acid and alkali
resistance,hasn't corrosion or moth-eaten and has ocidation resistance.
4.it has conveninent construction,light weight and convenient uses.
