Analysis of the manufacturing process of blended fine yarns with the content of flax fibres

The recent animation in the flax fibre market is mainly due to the possibil ity of processing flax in mixture with other fibres. Therefore, alongside o f conventional flax spinning techniques, other spinning techniques are more and more widely adapted to spin flax fibres. A new technology is emerging, in which an essential role is played by cotton or wool spinning machinery The reasons for this trend are: to have flax fibre processed on machines th at are more productive than conventional flax-processing machines; to impro ve working conditions; to solve the problem of utilisation of low grade fla x fibres (flax tow); and, last but not least, to improve the quality of lin en textiles by mixing flax fibre with other fibres. However, to process fla x fibre by a system other than the flax spinning system, additional operati ons have to be included in the process to adapt the fibre to the machinery. A number of methods have been developed in Poland and elsewhere for mechan ical modification of flax fibre. A process for manufacturing short flax fib re, based on Befama and Falubaz machines, has been developed at the Technic al University of Lodz. The quality parameters of short flax fibre are super ior to those of short flax fibres produced by foreign manufacturers. The fi bres have been processed with initial proportion of 50%flax/50% cotton yarn s of linear densities 25 tex, 30 tex, and 40 tex.
