Bonded Ultra Dee polyester thread has set an industry standard because of its high strength and controlled stretch, its stability in sunlight and its resistance to needle heat, abrasion, salt-water and mildew. It will very seldom fray at the needle eye, and its bonded finish is so consistent that machine tension does not have to be continually adjusted.

Sailmaker's thread needs to be pulled up off the top of the tube. This puts an extra twist in the thread which contributes to its strength and helps to keep the thread from unlaying. It also enables a smooth feed off the top of the cone which eases tension problems.
