Hemp fibre nonwovens are developed in the research work with a goal to the materials surface modification applying metal and metal oxide nanoparticles. It is planned to investigate the electrical properties of nonwovens to determine their ability to serve as radiation insulation. Fibres were cut into 5 cm long, some of them passed through Laroche Cadette equipment twice that opens the fibres and part manually combed before making nonwovens. Carded webs were formed from prepared fibres by parallel-laid carding method. The fibres were opened by using Laroche Cadette equipment, web was formed web only by mixing hemp fibres with 15% Tencel fibres. Clean hemp fibres webs were created from manually combed fibres. Hemp fibres nonwovens were created by using hydroentanglement method.
