Silk fabric is lightweight, delicate, and prone to slipping, so special attention must be paid to machine settings and sewing techniques. First, select round-point needles in size 70/10 or 80/12 to prevent snagging caused by overly thick needle tips, and adjust the stitch length to 2–2.5 mm to reduce fabric stretching. For thread selection, it is recommended to use 60-count high-density polyester thread or thread specifically designed for silk, and ensure that thread tension is set to a medium-low level to avoid puckering caused by overly tight stitches.
During operation, both the feed dog height and presser foot pressure should be appropriately reduced. Using a silicone presser foot or placing a thin sheet of stabilizing paper underneath can improve fabric control and prevent slipping. If stitch lines appear distorted, check the timing between the hook and needle to ensure precise loop catching. For curling edges, pre-press the fabric with a low-temperature iron for shaping or use a rolled-hem presser foot to assist with stitching. After finishing the sewing process, promptly clean out lint accumulated on the needle plate to prevent residual fibers from affecting subsequent operations.
