Sewing thread construction

Not all sewing threads are equal, because every sewing application requires the appropriate raw material in combination with the corresponding sewing thread construction. This is why there are various sewing thread technologies available – each sewing application requires a suitable sewing thread. We have had a significant influence on the production of many sewing threads.

Micro Core Technology®

Micro Core Technology® (MCT)

The Micro Core Technology manufacturing process developed by Gütermann is not comparable to any existing sewing thread design. It is the first core spinning process based on microfilament polyester, making threads of the highest quality which also offer optimum process reliability. The result: Extremely uniform and smooth seams with an exceptionally fine thread cross-section and silk-like shine. The textile surface character of our MCT threads is formed by loops known as micro-loops. MCT threads also have a high mechanical load capacity and are absolutely safe for use with all sewing machines.

Smoother, finer, shiner –
Micro Core Technology® advantages at a glance
