Abstract:

The paper discusses the optimisation of some of the working parameters in the processes of extracting and manufacturing unretted flax fibres to eliminate impurities and attain a certain degree of fibre fineness and mean length in the flax yarns obtained. Unretted flax yarn is obtained by a new wet spinning system with a twister tube. This yarn has a new structure, and so its fibres are located parallel to the yarn axis. Yarn strength is determined by recovering the link substances after drying. Their low strength recommends these yarns for woven fabrics processed on machines with medium weaving speed.
