Comprehensive characterization and performance mapping of knitted architectures for active sportswear applications

Advanced engineering of athletic apparel requires an intricate understanding of mechanical, structural, and thermo-physiological behavior under conditions of intense activity and regular maintenance cycles. This study presents an exhaustive experimental mapping and characterization of 26 separate knitted fabric specimens manufactured from a cross-section of primary apparel materials, including natural cotton, virgin polyester (PES), recycled polyester (REC PES), and elastane (EA) blends across multiple stitch arrangements (single jersey, three-yarn fleece, mesh, rib, piqué, interlock, and spacer configurations). The experimental framework comprised the full 16-stage testing pipeline: atmospheric conditioning, fabric mass, stitch density profiling, pneumatic bursting pressure, ball burst strength, Martindale abrasion failure cycles, pilling evaluation, multi-axial extension and elastic recovery, strip-tensile breaking strength, washing dimensional shrinkage, loop spirality deformation, air permeability, vertical capillary moisture wicking, washing color fastness, dry/wet crocking fastness, perspiration fastness under acidic/alkaline media, and phenolic yellowing storage risks. The empirical findings demonstrated that while 100% cotton specimens provide exceptional initial soft touch and moisture intake, they fail core industrial durability metrics, yielding severe lengthwise washing contraction up to -13.3% and loop spirality up to 5.8%. In contrast, dense double-knit structures, notably 100% PES Interlock variants, exhibited supreme structural locking and an unprecedented ball burst resistance of 981.0 N. Recycled synthetic variants achieved technical and performance parity with virgin counterparts across all mechanical and fastness parameters. Based on this multidimensional data pool, a localized zoning structural matrix (body mapping layout) is proposed for engineered athletic jersey optimization.
