Investigation on the filtration property of nonwoven geotextiles

WEI Qu-fu (Dept. of Text. & Cost. Engn., Anhui Institute of Mechanical & Electrical Engineering, Anhui Wuhu 241000, China)  
Nonwovens have 3 - dimensional structure of fiber network, which makes the ideal filtration materials in civil engineering. Nonwoven geiotextiles tend to become thinner under pressure in civil engineering and structural change of nonwoven geotextiles under pressure will affect their filtration properties. The filtration property of nonwoven geotextiles is analyzed. It has certain instructive values for development and applications of nonwoven geotextiles.
