Working with technical fabrics, especially elements like slings, requires not just strong but ultra-strong threads capable of withstanding extreme loads, abrasion, UV exposure, and temperature fluctuations. Gutermann Tera 20 threads were developed specifically for these tasks—high-tenacity polyester threads ideal for sewing slings, seat belts, tactical gear, rescue equipment, and technical textiles.
Gutermann, a world leader in thread production, uses innovative Micro Core Technology®, providing unrivaled strength and stability. Tera 20 threads guarantee a reliable seam, even in the most complex and demanding applications.
Advantages
1. Extreme Strength
Tera 20 is one of the strongest threads in the Gütermann line. It is designed to withstand high mechanical loads, tension, and friction. This makes it the ideal choice for applications where safety and functionality in critical situations depend.
2. Ideal for heavy technical fabrics
These threads are specially designed for working with dense, rigid, and multi-layer materials: slings, cordura, reinforced fabrics, PVC materials, tarpaulins, synthetic belts, and technical textiles.
3. High resistance to external factors
Tera 20 is resistant to UV, moisture, aggressive chemicals, oils, and salts. Even under intensive use, it Outdoors, in the rain, in seawater, or in extreme heat, the seam remains secure and maintains its integrity.
4. Compatibility with industrial sewing equipment
The thread is designed for industrial use: Columnar, coverstitch, sleeve, and heavy-duty sewing machines easily handle the Tera 20 without breakage or failure. This speeds up the production process and avoids defects.
5. Smooth and stable stitches
Thanks to Micro Core Technology®, the thread has a perfectly smooth surface and a uniform structure along its entire length. This allows for the creation of clear, aesthetically pleasing seams, which is important even in technical products where appearance is also important.

Recommended Use
To get the most out of your Gütermann Tera 20 thread, follow these professional recommendations:
Needles
For machine stitching, use #120-140 needles with reinforced points (e.g., LR, S, DI, or TRI needles). They ensure precise stitching through heavy fabrics and prevent skipped stitches.
Equipment Settings
Adjust the upper and lower thread tensions according to the fabric thickness. The Tera 20 requires a higher tension, but with the correct settings, it produces a perfect, distortion-free seam.
Sewing Speed
Work at medium to high speeds, provided your machine has sufficient power. Tera 20 is suitable for industrial applications and can withstand high speeds without overheating.
Color Selection
Although this is an industrial thread, the manufacturer offers a wide range of shades. You can choose a color that matches the material or use a contrasting color for a decorative effect.
Storage
Store spools in a dry place, away from sunlight and extreme temperatures. This will preserve the thread’s properties throughout its entire shelf life.
