How to judge the quality of geotextile?

Frist, We used to see the appearance of the short filament

geotextile,especially experienced procurement and inspection personnel, they usually use eyes to see to some extent can judge of nonwoven fabric quality.The same quality standard short silks, the color is pure white means quality good.

Second,about the compactness of the geotextile,we need to take a look at it and feel the compactness of the geotextile.Generally, the quality of the compactness is larger means the quality is better, and the density of geotextile obviously affects the quality of geotextile.

Third method,laboratory tests: take a piece of short filament geotextile samples sent to the laboratory for testing is accurate and convenient method, laboratory test can clear short filament geotextile product breaking strength, elongation, CBR bursting strength index of geotextile related parameters and so on.Customers can compare their engineering construction parameters from these parameters, and it is obvious that the geotextiles are qualified or not.
