Abstract
Present requirements of the modern man impose the realization of textile products with an increased comfort that should provide, besides their basic functions, the conditions of easy motion, aesthetic aspect, easy maintenance etc. These requirements are conferred by the textile products containing elastomer. The development of elastomer fibers and filaments based on polyurethanes, as well as the progress in textile mechanical and chemical technologies, offer the possibility to obtain textile products with increased elasticity. Wool-types yarns with different torsion degree (twist factor 72÷128) and elastomer content between 4.5 and 11.5% have been realized. This work studies the influence of torsion degree and the elastomer content on yarn characteristics.
Keywords: torsion degree; twist factor; elastomer; yarn; characteristics
