Classic geotextiles

The classic geotextiles are fabricated in two steps, i.e. the production of fibres, filaments, slit films (tapes), or yams followed by converting these constituent materials into a fabric. The constituent materials required for the manufacture of geotextiles are produced using various techniques, as discussed below."... 

The above linear elements, namely filaments, fibres, slit films, or yams, can be converted into several types of classic geotextiles, as briefly discussed below. 

Giroud (1996) started firom the classical Kozeny—Carman equation for the hydraulic conductivity of porous media and obtained the following equation (Eq. [8.12]) to theoretically evaluate the permeability of nonwoven geotextiles ... 

Besides the classic fields of application of clothing (pullover, underwear, stockings, sportswear, bathing suit fashions) and home textiles (net curtains, bedspreads, awnings, tablecloths, covers for furniture), knitwear is also used for technical textiles, including for helmet structures, medical textiles, geotextiles for dike and road construction, filter materials, material for insulation, and nets.
