When evaluating raw cotton, focus on Thread Count (TPI) and GSM (Grams per Square Meter) to determine fabric density and weight. For high-quality apparel, look for Combed Cotton which removes short fibers for a smoother finish, or Carded Cotton for a more natural, textured feel. Ensure the Yarn Count (e.g., 30s, 40s, 60s) aligns with your end-use; higher numbers indicate finer, softer yarns. Additionally, verify the Shrinkage Rate, which should ideally be below 3-5% for pre-shrunk or sanforized fabrics.
