HEMP GROWTH AND FIBRE PROCESSING POSSIBILITIES IN LATVIA

Ilze Baltiņa, Zaiga Zamuška, Veneranda Stramkale, Guntis Strazds

Abstract


Use of hemp fibre is rapidly increasing in Europe. This tendency is related to carbon and glass fibre substitution with recycled and biodegradable raw materials for use in car production. Scientists and manufacturers work to obtain new composite materials where hemp fibre will be as reinforcement. Hemp fibres are light and with high tensile strength comparing with other technical fibres. Advantage – eco–friendly utilization possibilities. The research work to determine hemp fibre efficiency was carried out for two years at the Latgale Agricultural Research Centre. In this work different hemp fibre varieties were used. To determine the most suitable varieties for Latvian climatic conditions all the varieties were tested at the laboratories of Riga Technical University, Institute of Textile Material Technologies and Design. We are looking for new possibilities to make technical textile samples from different hemp fibre varieties. In cooperation with Laboratories of the Scientific Institute of Food Safety, Animal Health and Environment “BIOR” the amount of tetrahydrocannabinol (THC) in different variety cannabis plants were determined. It was concluded that amount of THC of different open–air cultivation varieties grown in Latvia is different but anyway this amount is much below the acceptable norm.
