Superior's Bonded Nylon #277
Bonded Nylon #277 (also known as Tex 270 or 4-cord) is a heavy-duty thread used for a variety of applications including stitching on leather, tarps, canvas, and other types of thick material when a bold, visible stitch is wanted. Many upholsterers who work with leather furniture, saddles, and apparel choose to stitch with Bonded Nylon #277 as it has excellent strength and binds materials together in a well-formed lockstitch.
Our Bonded Nylon #277 is available in many colors wound onto 1 lb. cones. Along with standard black and white colors, which are the most commonly-used colors of bonded nylon #277, we offer a selection of bold and bright colors. Purple, blue, pink, orange, green and other hues make for fun contrasting stitches and command attention when used appropriately. It is widely popular to use contrasting threads to achieve a designer look for leather goods. Because Bonded Nylon #277 is a thick thread, the contrasting colors of the upholstery fabric and the thread make for a very appealing combination.
Saddle makers, boot makers, and other western-wear producers like sewing with Superior’s Bonded Nylon #277 because of the it's high strength (also known as high tenacity) qualities and ability to keep a strong, sturdy stitch, even when sewn through many layers of webbing, canvas, or leather. Bonded nylon #277 has a breaking strength of about 45 lbs.
We recommend using a size #24 or #26 needle when sewing with bonded nylon #277. It's a thick thread and should be paired with a larger-eye needle to reduce thread breakage or uneven tension. The larger the needle size, the larger the eye of the needle.
The bonding agent that coats our bonded nylon threads increases its breaking strength and helps reduce friction that develops at the needle. Commercial sewing machines and industrial sewing machines have a much higher stitch-per-minute rate than home sewing machines, so the bonding agent mitigates thread breaks and acts as a barrier between the thread and the heat from friction as the thread passes through the needle.
