Popis:	In drainage applications, smart geotextiles containing polypropylene and polyester staple fibers, along with other synthetic waste fibers (20–1000 denier) prepared by a special needle-punching mechanism, have been used as filling materials. A three-layer non-woven/drainage layer/non-woven structure was adopted in the manufacture of these smart geotextiles. Typical two or three-dimensional structured geonet composites having a similar thickness to the smart geotextiles were used as reference materials to compare the drainage properties. The variation of thickness, in-plane permeability, and transmissivity with compressive stress were evaluated, and the differences and similarities between the smart geotextiles and geonet composites were interpreted.
