  1. What type of thread is used in the bobbin?

  2. I was told by the Singer Sewing Rep that this tread (outdoor) has a coating and I can not be used safely in my home machine, that it will gum it up and damage it over time. It should only be used on an industrial machine. Is this true? They also said I could use regular upholstery thread but ONLY in the top thread, never in the bobbin. My machine is brand new so I want to do the right thing. Please let me know. Thank you

    • The outdoor thread is bonded, the coating will not come off in your sewing machine. Heavy threads are a little more difficult to use, but this thread and the upholstery thread can be used on a home machine on top and in the bobbin. Be sure to use a large needle 16 or 18 topstitching is best, lengthen the stitch and increase the upper tension.

  3. What is the tensile strength of this thread?
