Abstract:

We present the results of tests on rotor-spun blended yarns, made with a high proportion of flax, and rotor-spun all-cotton yarns. Of special concern was the method of preparing the fibres and sliver. The flax/cotton sliver was made up of medium-long cotton, and the flax fibre was shortened and reduced in diameter by mechanical cottonising. The basic composition of the flax/cotton sliver was 30% cotton and 70% mechanically cottonised flax. The optimum linear density of the yarns was 40 tex. The experiments enabled the optimum values of twist and linear density to be found, at which the quality parameters of the yarns produced were acceptable. In addition, a comparative analysis of the produced cotton yarn and flax/cotton yarn was made. The flax/cotton yarn with a high proportion of flax is suitable for both weaving and knitting.
