Learn how GSM affects opacity, durability, drape and shrinkage in activewear — avoid common mistakes and choose the right fabric weight by garment and climate.

AI-driven color forecasting improves accuracy and feasibility for activewear, reducing sampling waste and aligning trend palettes with production-ready fabrics.

Martindale testing measures fabric abrasion using a figure‑eight motion to count rub cycles and assess pilling, mass loss, and durability for activewear.

Practical checklist to vet Chinese factories, build precise tech packs, enforce multi-stage quality control, diversify suppliers, and manage customs and delivery.

Create detailed tech packs for Chinese activewear factories: flat sketches, size charts, BOMs, bilingual files, sampling timelines and clear communication.

Step-by-step QC for high-volume activewear: tech packs, pre-production samples, inline inspections, fabric and trim testing, and AQL final audits.
