Anotācija This article presents development of hemp fibers non-woven materials for insulation applications in building industry, obtained with two different technologies – thermal bonding and needle punching. Two types of dew-retted hemp fibres harvested in year 2010 – a local dioecious variety “Purini” and an EU registered monoecious industrial hemp variety “Bialobrzeskie” grown in Latvia, were used and their end-product properties compared. The resulting thermal bonded and needle punched hemp nonwoven materials with a different structures and thicknesses are characterized to determine their physical properties such as thickness, weight per unit area, water vapour transition, porosity, thermal resistance and thermal conductivity to evaluate their suitability as alternative insulation materials. The samples properties between both used technologies were compared. The influence of hemp variety on fabric properties was also estimated. Keywords: Hemp fibres, nonwoven materials, needle punched, thermo bonded nonwovens.
