What are the differences between nonwoven and woven geotextiles?
Nonwoven geotextiles are made of directionally or randomly orientated fibres, filaments or other elements, mechanically and/or thermally and/or adhesively bonded
Woven geotextiles are produced by interlacing two or more sets of yarns, fibres, filaments, tapes or other elements
Which role does the polymer play in the properties of the geotextile?
Different polymers are used for the production of geotextiles. The selection of a polymer depends mainly on properties like melting point, density, melt flow index etc that influence the different production processes.
Usually the polymer is modified using additives and stabilizers in order to improve the characteristics. It is the final manufactured product that is of primary interest to the end user.
What is the difference between geotextiles and geosynthetics?
Geosynthetics is the generic term for products where at least one component is made from a synthetic or natural polymer used in contact with soil and/or other materials in geotechnical and civil engineering applications
Geotextiles are planar, permeable, polymeric textile products and are one type of geosynthetics.
