The Capillary Flow Pore Size Test provides a more precise representation of the openness of all pore sizes within a fabric.
Geotube marine technology has protected shorelines, rebuilt beaches, and reclaimed land from the sea for more than 45 years. Geotube containment technology is a proven, cost-effective method for a variety of shoreline protection and marine construction applications.
TenCate, manufacturer of Geotube materials, is the world's leading provider of industrial fabrics. Armed with an extensive background and knowledge of marine textiles, the company examined and analyzed many fabric testing methods and data measurements to better identify the 'openness' oftheirwoven Geotube fabrics. TenCate determined that other criteria, beyond the traditional AOS value, should be taken into account when selecting a textile for a marine application. One of those key factors was the pore size of a fabric.
'We've identified a potentially better way of looking at a fabric,' said Mark Gunzenhauser, Vice President Sales, TenCate'' Industrial Fabrics. 'Rather than relying only on AOS, we strongly recommend that pore size be inspected. It plays a major role with issues of containment and structural integrity for a marine application.'
TenCate develops and produces materials that function to increase performance, reduce cost, and deliver measurable results by working with our customers to provide advanced solutions.
Geotextile Testing 101
The hydraulic properties (those directly related to filtration and drainage functions) of geotextiles are governed by the pore size, pore size distribution, and the porosity of the fabric. An optimum fabric must have a small enough pore size to retain the soil, while also being permeable enough to allow for water to escape freely from the soil. The testing and measurement of a fabric's porometry is inherently challenging due to the size and magnitude of pores within a textile.
