Abstract: The article describes research studies in the laboratories of the departments of “Spinning Technology” and “Silk Technology”. For this purpose were taken samples of cotton fiber and silk waste from the carding machine in the spinning process, 100% cotton fiber waste, 50% cotton fiber, 30% silk, 20% mulberry bark fiber, 70% cotton fiber, 15% silk, 15% mulberry bark fiber, non-woven fabrics were produced from 75% cotton fiber 10% silk 15% mulberry bark fiber blends. The single-period elongation deformation of the obtained non-woven fabrics was determined using the device “Stoyka”.
Keywords: Total deformation composition, elastic, plastic deformations, relaxation process, middle square value, coefficient of variation, significant or insignificant indicators
