This is a smooth, bonded polyester outdoor thread that is perfect for sail and canvaswork. Bonded Ultra Dee polyester thread has high strength and stretch control, stability in sunlight (UVR), and resistance to needle heat, abrasion, saltwater and mildew. Our polyester thread very seldom frays at the needle eye, and the consistent bonded finish minimizes the need for continual machine tension adjustments. Use this Tex 70 thread with a #16 or #18 needle. Perfect for use on sails, tents, boat covers, awnings, outdoor canvas covers and tarps.

When using sailmaker's thread, make sure to pull the thread up off the top of the cone. This will add an extra twist in the thread which increases the thread strength, helps keep the thread from unlaying, and eases tension problems.

Features:

• Improved resistance to strength loss from UV exposure over standard polyester filament thread
• Good seam strength
• UV resistant
• Non-wick treatment to limit moisture migration
• Consistent diameter and excellent ply
