Tera 80

When sewing clothing, especially from technical and dense materials, it’s important to choose threads that provide not only strength and reliability, but also stability at high speed. Tera 80 from Gütermann is just that—a strong, thin, industrial-grade synthetic thread designed for a wide range of sewing operations, from seaming to finishing.

Tera 80 is a versatile textured thread made of 100% polyester, characterized by high abrasion resistance, uniformity, and optimal thickness for sewing garments from a wide range of fabrics. This is one of the most sought-after threads in the Gütermann Tera line due to its balanced strength and elasticity.

Advantages

1. High strength with a thin thread

These threads ensure a secure connection between garment elements, even under intense use. At the same time, they remain thin enough not to overload the seam or deform the fabric, ensuring a neat and smooth appearance.

2. Ideal Thread Structure

The threads are produced using modern twisting and heat treatment technologies, ensuring high uniformity along the entire length and the absence of thickening, delamination, and lint.

3. Versatility

Tera 80 is suitable for use on all types of industrial equipment, including straight-stitch, overlock, and coverlock machines. Thanks to its good elasticity, the thread does not break even at high sewing speeds.

4. Wear and Chemical Resistance

The thread is resistant to repeated washing, abrasion, chemical exposure, UV light, and ironing. This makes it ideal for casual and professional wear.

5. Wide Color Palette

Gutermann offers a wide range of shades for Tera 80, making it easy to match any fabric and achieve a precise color match.

These threads are resistant to aggressive environments and are often used in the production of workwear, uniforms, medical clothing, and service clothing. They cope well with the stresses of use and washing.

• Technical textiles and accessories

Thanks to its strength and durability, Tera 80 is suitable for sewing technical textiles such as linings, bags, backpacks, belts, gloves, and covers.

• Seam finishing in underwear and underwear

Can be used for joining seams in thin garments without creating stiff areas and ensuring comfort during wear.

Recommended Use

To achieve the best seam quality, it’s important to use the correct thread for the task and equipment.

Needle Selection

Recommended needle sizes: 70-90. For heavy fabrics, use needles with reinforced points; for knits, use ball-point needles.

Sewing Machine Settings

Works reliably at speeds up to 6,000 stitches per minute. A medium tension setting is recommended to ensure a smooth seam without puckering or skipping.

Using as Bottom and Top Thread

Tera 80 can be used as both the top thread and the bobbin thread. This is especially important when sewing dense fabrics, where even stress distribution across the entire seam is required.

Color Matching

A wide range of colors allows you to achieve a perfectly invisible seam. Match the shade to the fabric or create decorative contrasts.

Proper Storage

Store spools in a dry place, avoiding direct sunlight. It is not recommended to leave the threads in direct sunlight to prevent fading.
