If an industrial sewing machine operator is sewing with excessive tension, it can literally stretch the thread as it’s being sewn and weaken the seam, which compromises the integrity of the product that’s being sewn.
Continually sewing with this high of tension also adds wear and tear to sewing machine parts, which can abrade or damage the thread even further, taking away a good amount of its tensile strength.
In our latest quick tip video, I explain how sewing tension involves the stretch or elongation of a thread and affects the strength of a seam. Too much thread tension can also damage the machine, so I explain what to do if you’re troubleshooting an issue with seam quality.
