In this scientific study, research was conducted on the comprehensive evaluation of knitted fabrics made from PAN yarn with the aim of efficient utilization of local raw materials. To determine the most optimal variant of knitted fabric, it is recommended to consider a number of factors that shape the structure and properties of the fabric, as well as to apply appropriate evaluation methods. The analysis results showed that the quality indicators of the produced samples have varying levels of priority across different variants. Consequently, the necessity arose to identify an optimal variant characterized by low raw material consumption and the best quality indicators. For this purpose, a comprehensive evaluation method was employed to compare statistical data with the experimental results obtained for PAN yarn knitted fabrics. The obtained samples were compared according to quality indicators such as bulk density, air permeability, breaking force, elongation at break, recoverable deformation, and shrinkage. PAN yarn with a linear density of 31×2 tex was used as the raw material. To integrate the quality indicators and define quality limits, a comprehensive evaluation diagram was constructed. The values of technological parameters and physical-mechanical properties of PAN yarn knitted fabrics were plotted along each axis of the comprehensive diagram. Based on the analysis of technological parameters and physical-mechanical properties of PAN yarn knitted fabrics, studies were carried out to identify variants with superior quality characteristics.
