Introducing the 1oz spool of Bound Tex 135 Black Polyester Thread, the professional’s choice for heavy-duty outdoor and marine applications. This premium bonded polyester thread, Tex 135, is engineered for superior performance and durability. The smooth, consistent bonded finish ensures excellent sewability, minimizing frustrating fraying and reducing the need for continuous machine tension adjustments. It boasts exceptional high strength, reliable stretch control, and a left-twist structure optimized for powerful industrial and professional sewing machines.

Engineered as a Tex 135 UV-resistant marine Thread, it maintains reliable stability and strength when exposed to harsh sunlight, preventing premature strength loss. As a highly abrasion-resistant marine sewing thread, it efficiently handles friction from repeated use and movement. Furthermore, the specialized finish provides superior anti-wicking outdoor thread performance, preventing moisture migration through critical seams—an essential feature for durable sewing thread for boat covers and canvas, large awnings, and tarps.

This size is designed for industrial sewing machines and is too large for home machines. For optimal results, use this Tex 135 thread with a #20 or #22 needle when working with fabrics weighing more than 10 oz. per square yard. Choose this durable thread size for maximum longevity in challenging environments.
