Item Description

Tenara® Lifetime Guaranteed Thread features unique fluoropolymer fiber construction that extends the life of fabric seams and ultimately the products in which it is used. GORE™ Tenara has high strength and durability that for over ten years has proven to be unaffected by exposure to UV rays, cleaning agents, pollution, saltwater, air, rain, and snow.

Great for outdoor, awning, and marine applications, Tenara thread will not rot if left outside all year round. Remains colorfast even in extreme temperatures and frost. Although more expensive, Tenara is a greater value than other polyester threads when considering life span and re-stitching costs. Choose Tenara thread to improve the performance of outdoor fabrics where seam life and integrity are of the utmost importance.

Tenara M1000 is similar in weight to V-92. Use a smaller than normal needle (#16 or #14) to hold thread in proper loop and to create smaller holes that prevent fabric leakage. Tenara sews very well and does not require as much upper tension as normal polyester thread.

Sailrite's Hints for Sewing with Tenara Thread

Sewing with Tenara/Gore-Tex thread can be difficult and frustrating at times, but issues can easily be fixed by making a few adjustments. Here are a few tips for working with Tenara and how to adjust an Ultrafeed™ machine to better sew with the thread.

Tenara thread is very slippery. Using a smaller needle can reduce slipping issues. We recommend using a #16 or #14 needle and for Ultrafeeds, Serv7 needles work well. When a needle is too large, the shaft of the needle won’t hold the slippery thread firmly enough against the fabric to create a proper loop, therefore the hook cannot catch the loop and form a stitch.

When using an Ultrafeed Sewing Machine, if reducing the needle size and using a Serv7 needle doesn’t work and stitches are still being skipped, try one or more of the following:

  • Lower the needle bar slightly. Doing so has a tendancy to increase the size of the loop and make it easier to be caught by the hook to form a stitch.
  • Slightly rotate the needle in a counterclockwise direction. The long vertical groove in the needle normally faces to the left when you are facing the front of the machine. Now it will be angled slightly toward you.

On Ultrafeed machines, if the material puckers, stitch knots are pulled to the upper side of the material, or the thread is breaking try:

  • Increasing the bobbin case tension by approximately half a turn
  • Decreasing upper tension by approximately half a turn

Thread breakage can also be a result of thread “kinking” as it comes off the cone. Kinks cause tension and inconsistency. Remove the kinks before they get to the machine. Try moving the thread stand farther away from the machine or suspending the cone horizontally to remove kinks as you sew.

Feel free to experiment with these adjustments in order to fine-tune stitch quality on Ultrafeed and other sewing machines as well.
