Coated Needles Needles may be available with a special non-stick coating that will reduce heat buildup and allow the needle eye to remain clear of thread or garment fibers. These needles are referred to as Teflon coated or Cool Sew, depending upon the manufacturer. Their ability to reduce friction makes them ideal for synthetics like cordura and nylon. Thread Breakage Needles can contribute to thread breaks in the following ways: Using a needle with an eye that is too small in relationship to the thickness of the thread. A burr in the needle eye or along the front of the blade. High temperature caused by friction during the sewing process. Rule of Thumb If a needle is too thick, it breaks the fabric's threads. If a needle is too thin, it causes skipped stitches. www.hsi.us care@hsi.us 181
