When evaluating silk chiffon, the most critical technical metric is the Momme weight (mm), which typically ranges from 6mm to 12mm for chiffon; a higher momme indicates a denser, more durable weave. You must also verify the fabric construction (e.g., 20/22D grade 6A silk) to ensure a smooth, lustrous finish. For printing, inquire about the printing method (Digital Inkjet vs. Screen Printing)—digital printing offers higher precision for complex patterns and lower MOQs, while screen printing is more cost-effective for large-scale production with high color saturation.
