A blackout curtain sewing machine features powerful motors, sharp cutting needles, and strong feed dogs to stop fabric slippage during sewing as it is made for dense heavy materials that block light and noise. Other machine parts that further enhance sewing effectiveness include coatings that lessen fabric cling, thick-thread plugs,’ bespoke anti-static covers, seamless covers, glue lap joints, and intricate shut seams that withstand bending forces and thick gauge stitching. In commercial settings, some machines are designed to professionally finish blackout curtain for home theater, bedroom, or other places.
