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. This polyester thread very seldom frays at the needle eye, and the consistent bonded finish minimizes the need for continual machine tension adjustments. Perfect for use on sails, tents, boat covers, awnings, outdoor canvas covers, and tarps.

Use this Tex 90 thread with a #18 or #20 needle on 6–10-oz. fabrics (including all Sunbrella^® fabrics). We recommend a #20 needle when sewing with the Sailrite^® Ultrafeed^® Sewing Machine.

Sailmaker's thread should pull up off the top of the cone for a smoother feed to the sewing machine and to add an extra twist in the thread. The extra twist increases thread strength, helps keep the thread from unlaying, and eases tension problems.

• Good seam strength
• UV resistant
• Non-wick treatment to limit moisture migration
