SUMMARY:

Compression knitted fabrics are functional textiles widely used in medical, sports, and rehabilitation applications due to their ability to exert controlled pressure on the body, promoting venous return, muscular support, and tissue recovery. In this context, the present study aimed to evaluate the mechanical behavior of compression knitted fabrics produced under laboratory conditions and to discuss the expansion of their potential applications using accessible experimental methods.
Seven jersey-structured knitted samples were produced using a laboratory-scale circular knitting machine, with different proportions of polyamide and elastane and variations in the loop length factor (LFA). The samples were subjected to hysteresis and elasticity tests according to ASTM D4964, immediate and long-term recovery tests, microstructural analysis using optical microscopy, and interface pressure measurements using an adapted experimental system based on a pneumatic chamber and a clinical sphygmomanometer. The obtained data were analyzed using descriptive statistics.
The results indicated that the proportion of elastane significantly influences the mechanical behavior of the knitted fabrics. The samples exhibited interface pressures ranging from 2.8 to 17.4 mmHg, allowing their classification within low and moderate compression ranges. Formulations with intermediate elastane proportions presented the best balance between elasticity, dimensional recovery, and mechanical stability, whereas higher elastane contents did not lead to proportional performance improvements. Recovery analyses also indicated a high dimensional recovery capacity over 72 hours, suggesting the predominance of reversible deformations. Overall, the results demonstrate that simplified experimental approaches can provide relevant information for the mechanical characterization of compression knitted fabrics and support the development of alternative materials for academic and industrial contexts.
