When evaluating polyester silk (silk-like) scarves, focus on the fabric weight (measured in GSM - grams per square meter); a range of 50-70 GSM is ideal for a premium hand-feel. Pay close attention to the weaving technique, such as satin, twill, or chiffon weaves, which dictate the luster and drape. Ensure the printing method (Digital Printing vs. Screen Printing) provides a high color penetration so the design is visible on both sides, and verify that the hemming quality (Hand-rolled vs. Machine-stitched) meets your target market's luxury or mass-market positioning.
