Abstract
A sewing thread comprising a first yarn that is a filament yarn made or a fire resistant polymer and a second yarn that is a synthetic and/or natural yarn. The sewing thread may also contain a third yarn that is a synthetic and/or natural yarn. The first, second, and third yarns each have a first twist in the same direction. The first, second, and third yarns are then combined to form the sewing thread using a second twist which is in the opposite direction of the first twist. No bonding agent is used in the sewable, fire resistant thread.
