The FTC requires generic fiber names on most textile products. Manufactured fibers must use those names, not a trademark standing alone. Fibers at 5 percent or more by weight are named in order of predominance. The care tag is a different label. Use both when they exist.
All-purpose polyester holds a garment seam. Quilting thread has two jobs of its own: piecing, and quilting that is meant to show. Weight and fiber decide whether the seam disappears. Computerized versus mechanical machines is a third comparison, not the first door.
Longer lectures: fiber ID, all-purpose vs quilting thread, all three comparisons.
