The heat-bonded nonwovens (NW) are used for geotextile production due to the simple production cycle and low processing cost. To create the geotextile with desirable properties the mix of fibres and additional reinforcing methods are used. The series of NW composites for experiments are made from natural and synthetic fibres mix by compressing method. Hemp fibres, pretreated with sodium hydroxide, recycled polyethylene terephthalate fibres and polypropylene fibres are utilized for NW webs production on laboratory carding machine 337A MESDAN. Additionally the NW webs are reinforced with thermoplastic sieve from one and both sides. The NW composites are produced on laboratory press (LP-S-50/S ASTM) with pressure 26±2 kN at 140± 2 ºC temperature. The produced NW composites samples surface parameters are calculated according LVS EN ISO 139:2005. For testing of NW mechanical properties, according LVS EN ISO 13934-1-2001, Zwick universal testing machine is used. For determination of NW resistance to water penetration hydrostatic pressure test according LVS EN ISO 9073-16:2009 and air permeability EN ISO 9237:1998 are applied. The comparison of obtained results with industrial prototype is performed.
