Changes in the Quality Indicators of Yarns Obtained From a Mixture of Cotton and Secondary Fibers with Different Composition

In the article, the physical and mechanical properties of yarns obtained by a pneumomechanical spinning machine from fibers of different composition are studied, in which the composition of fibers in the yarn is: 25% secondary fiber + 75% cotton fiber, 20% secondary fiber + 80% cotton fiber, 30% secondary fiber + 70 The effect of twists of 400 br/m, 500 br/m, 600 br/m on the properties of yarns made of % cotton fiber, 15% secondary fiber + 85% cotton fiber was determined.
