Gutermann Bulky Lock 80 Overlocker Thread 968 - 1000 Metres

No, Gutermann Bulky Lock 80 is specifically designed for overlocker and coverlock machines due to its construction and elasticity. Using it on a standard sewing machine can lead to performance issues.

It is ideal for knit fabrics, stretch materials, and any project where seam softness and flexibility are important, such as activewear, lingerie, and children's clothing.

High bulk construction creates a thicker, softer thread that provides excellent coverage and a cushion-like feel to the seam, making it more comfortable against the skin and visually appealing.

Yes, while soft, it is a high-quality Gutermann thread designed for durability in stretch applications. Its excellent recovery prevents seam damage during regular wear and washing.

The number '80' typically refers to the thread's thickness or tex value, indicating a medium-fine bulk suitable for overlocking. Lower numbers generally mean thicker threads.

While primarily intended for overlocker loopers, its softness might be desirable for decorative topstitching on certain knit projects if your machine can handle its thickness. However, it's not its primary intended use.

Check machine tension settings, ensure thread path is clear of snags, and verify that the thread is correctly seated in the looper guides.

Ensure the correct needle is being used for your fabric type and that the needle is inserted correctly and is not bent. Check looper timing.

Adjust looper tensions. Increase tension slightly if seams are too loose or wavy; decrease if too tight. Ensure consistent speed while sewing.

Ensure the thread is correctly placed in the looper(s) responsible for covering the edge. You may need to slightly increase the tension on the relevant looper.
