Novel Mock-Knitted Structures for Seamless Medical Compression Garments: Advancing Health Management with Thermal Comfort
摘要
Knitted compression garments are an area of increasing interest in several medical applications, including venous thrombosis, lymphoedema, gynecomastia, and more. Knitting technology offering better stretch, compression, and thermal comfort attributes provides great flexibility in engineering seamless medical compression garments. However, knitted structural alteration is a vast area that has remained unattended by researchers. Hence, this study focused on developing seamless knitted compression garments using a novel mock knitting technique. Various structures were developed using different elastomeric yarn counts [40/70, 40/120, and 40/170 denier (D)] to mimic rib (1 × 1, 2 × 2, and 1 × 3) and pique structures. These mock-knitted structures, having tailored float lengths and porosities, not only enhanced interface pressure but also influenced thermal comfort properties. Air permeability and thermal conductivity characterization proved that mock structures having coarser elastomeric yarns and longer floats are viable for the transmission of dry fluids and conducting body heat. Statistical data analysis provided evidence of the trend with p-values < 0.05. Moisture management, on the other hand, entailed a combined effect of structural porosity and material bulk contribution in making moisture channels through compression garments. Pilling Resistance also exhibited a similar parabolic trend with input variables. Statistically plotted 3D surface plots revealed unique trends of interface pressure at different measurement points providing deeper insights for designing compression stockings for specific body area.
