When sourcing Silk Jacquard, the Momme weight (mm) is the primary indicator of quality; for high-end garments, a range of 16mm to 22mm is standard. You must verify the thread count and weave density, as intricate jacquard patterns require high-precision looms to prevent snagging. Ensure the fabric uses 100% Mulberry Silk rather than synthetic blends unless specified. Additionally, check the colorfastness to light and rubbing (Grade 4 or higher) to ensure the complex patterns do not fade or bleed during processing.
