When evaluating embroidery fabric, you must focus on the Base Fabric Composition (e.g., 100% Cotton, Mesh, Organza, or Tulle) and the Thread Type (Rayon, Polyester, or Metallic). Pay close attention to the Stitch Density; a higher stitch count generally indicates a more premium and durable design. Additionally, verify the Fabric Weight (GSM) and Width (Effective Embroidery Width vs. Total Width) to ensure it meets your production requirements. For high-end garments, ensure the Colorfastness to Washing and Light meets Grade 4 or above.
