If you are seeking out threads for sewing a few of layers or some fairly thick or stiff fabrics, our filament thread is just what you need. The filament thread for sewing is available in polyester and Nylon along with many different sizes and colors. The filament thread for sewing will not fray, unravel or break when sewing at high speeds that results in stitching evenly and smoothly. We also apply adequate lubricants to further avoid skipped stitches, breaks and damage caused by extreme temperature of needle during sewing.
