Nonwoven geotextiles from short staple fibres

The dimension of the fibre, yam or filament has a direct impact on the mechanical and hydraulic properties of the geotextile. Fibre dimension is expressed according to its diameter, described in deniers or dtex, depending on the measuring system used (American or International System). Thread dimension is generally defined by its yam density. In the case of nonwoven geotextiles made from short staple fibres, fibre dimension is completed by the length of the cut fibres.
