Precision Textiles Meet Athletic Engineering
SURLINX masters every fiber and stitch – from proprietary yarn engineering to laser-cut components and performance embossing – crafting uppers engineered for court dominance.
Upper Production Process
Yarn to Performance Fabric
Yarn Processing: Convert high-tenacity nylon/polyester yarns into base fabric through warp knitting at our in-house microfiber mill.
Coating Treatment: Apply dual-layer wet PU impregnation—waterproof membrane (base) + micro-porous breathable layer (surface)
Laser Cutting & Positioning
Digital Nesting: AI nesting software optimizes pattern layout (↑18% material utilization).
Laser Projection: Project registration crosses/cutting lines onto fabric rolls.
High-Frequency (HF) Embossing
Precision Positioning: Secure cut pieces in IR-guided embossing slots.
Energy Activation: Apply 27.12MHz HF field to activate PVC/TPU molecules.
3D Texturing: Press at 10MPa to form brand logos/functional textures (depth: 0.5mm±0.1)
Stitching & Assembly Computerized Stitching
Auto-recognition of positioning holes for lockstitch assembly (12 stitches/cm).
Speed reduction to 600rpm at curves for uniform stitch density.
