CHANGES IN THE QUALITY INDICATORS OF YARNS OBTAINED FROM A MIXTURE OF COTTON AND SECONDARY FIBERS WITH DIFFERENT COMPOSITION

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