The physical-mechanical properties of double-layer knitted structures made from natural and chemical yarns were examined. Pilling resistance and stretchability were determined based on experiments conducted using GOST and BS standards. The influence of yarn composition and knitting density on these properties was identified. It was established that samples with 100% merino wool demonstrated the highest pilling resistance, achieving a mean score of 4.75 at a density of 350 courses per 10 cm. Stretchability tests revealed that blends containing 50% acrylic exhibited the greatest elongation, with a mean value of 17.67% at a density of 340 courses per 10 cm. The relationship between fiber composition, knitting density, and the resulting mechanical properties of the fabrics was clarified. The findings provide a foundation for optimizing the design of double-layer knitted fabrics to meet specific performance requirements.
