Thread Weight or TEX?

Posted by on September 6, 2017

When using different threads in the needle and bobbin we stand by the rule of using the same or lighter weight thread in the bobbin as is being used in the needle.  Following this rule helps the quilter achieve the best tension.  Since a 40-weight cotton thread has more drag because of the exposed fibers than a 40-weight poly thread I like to refer to the drag a thread has rather than just the weight.  So, a 40-weight cotton thread in the bobbin combined with a 40-weight poly thread in the needle would make good tension more difficult.  It is good to be aware of the fibers in the thread being used as well as the thread weight.

The most common weight of thread is determined by how much thread it takes to weigh a gram.  So, the finer the thread, the larger the number since it will take more fine thread to weigh a gram than a heavier thread.    The thread weight will be noted on the label with a # or wt. followed by its weight, such as #40 or 40 wt.

The TEX system of thread weight askes the question, “How much does 1000 meters of thread weigh?”  So, the heavier the thread, the higher the number.  This is the exact opposite of the weight measurement.  This will be noted on the label as TEX 30, or whatever the TEX measurement happens to be.  TEX 30 and 40 wt. are nearly the same.  TEX measurement is most often used on industrial thread labels.  Some companies note both measurements.

For best tension, consider the drag and the weight of the thread being used in the needle and bobbin.  Happy Quilting!

    I just bought a tinlixxie 18. First time to work with machine. It will not pick up the bobbin thread. I thought that coming from factory I would not have any issues
