Abstract: The evolution of a new class of PVD having sheath of braided yarns encasing a large number of core yarns is described. The flexibility and simplicity of the production process leading to the possibility of controlled variation in dimensional, mechanical and hydraulic properties of the product have been highlighted. A limited comparative evaluation of some typical variants of this drain made of jute sheath and coir yarns as core with three other commercial PVDs has been reported. The hygroscopic nature of jute and coir plays a significant role in altering the thickness, pore size, permeability and discharge capacity of the drain in the wet state under confining pressure.
