A novel optimization approach for bio-design of therapeutic compression stockings with pressure fit

Personalized compression therapeutic textiles: digital design, development, and biomechanical evaluation

“…Thus, the stocking dimensions could achieve the basic size fitness for each subject ( Wang et al, 2022 ). Third, for the mechanical tensile behaviors, through the physical mechanisms of Laplace’s law, the generated compression magnitudes were fundamentally determined by the textile tensions and Young’s moduli along the fabric circumferential stretched directions ( Shi et al, 2024 ). Therefore, the measured E c values varied for material mechanical requirements caused by the designed loop length settings and applied yarn combinations.…”

“…Furthermore, the curvature radii ( r 1 , r 2 ,., r n ) and curvatures ( ) of each slice were obtained by applying the Inline function, and dimensional circumferences ( Cir Leg ) of the subject’s lower limbs were calculated through ( Figure 2A ). In our previous study ( Shi et al, 2024 ), the insufficient pressure supply caused by biological irregular shape diversities was optimized by the redistribution development guidance. In detail, based on the characterized standard deviations of curvature ( SDC ) values of each slice, the profile irregularities of leg cross-sections could be classified by our clustered irregular (IR) levels.…”

“…In addition, the sizing motor settings could control the loop lengths of knitted loops to vary fabric mechanical tensile behaviors ( Shi et al, 2023 ). To effectively design the yarn and machinery variables, the quantitative relationships between the fabric circumferences ( Cir f ; cm) and pressure values ( P RQ ; mmHg) were fitted by our previous explorations through Eqs 1 , 2 , respectively ( Shi et al, 2024 ). Thus, the specific applied yarn material combinations and machinery parameters for each customized CTs could be digitally determined.…”
