Tex 135 Bonded Nylon Thread for Leather, Bags & Upholstery
Tex 135 (#138) bonded nylon 6.6 thread is a medium-heavy sewing thread for projects that need a stronger, more visible stitch. It is well suited to leather goods, bags, upholstery and other applications where seam strength and stitch definition matter..
How Tex 135 Bonded Nylon 6.6 Performs
Tex 135 bonded nylon 6.6 combines high tensile strength, abrasion resistance and controlled flexibility for demanding sewing applications. The bonded construction helps reduce fraying and improves thread handling during sewing, while the heavier Tex 135 size creates a stronger, more visible stitch for leather goods, bags, upholstery and similar projects.
Best Applications for Tex 135 Bonded Nylon Thread
Leather Goods: Suitable for bags, wallets, belts and heavier leather projects where a strong, visible stitch is preferred.
Upholstery: A practical choice for furniture, automotive interiors and other seams that need higher thread strength.
Footwear: Works well for shoes and boots that require durable stitching through thicker materials.
Canvas & Bags: Suitable for canvas bags, covers and other medium-heavy fabric assemblies.
Outdoor Gear: Can be used for backpacks and equipment where abrasion resistance and seam durability are important.
How to Use Tex 135 Bonded Nylon Thread
Machine Setup: Use a heavy-duty or industrial sewing machine that can handle Tex 135 thread and thicker materials.
Needle Size: Start with a needle around 130/21 to 140/22, then adjust based on the material, machine and stitch result.
Thread Tension: Adjust upper and bobbin tension gradually until the stitch is balanced and consistent.
Material Testing: Test the thread, needle and tension on scrap material before starting the final project.
- Stitch Testing: Test the machine, needle size and thread tension on a sample of the actual material before starting production.
Why Choose Tex 135 Bonded Nylon Thread
Medium-Heavy Thread Size: Tex 135 provides a stronger and more visible stitch than lighter thread sizes, making it suitable for thicker materials and more demanding seams.
Bonded Nylon 6.6 Construction: The bonded construction helps improve thread handling and reduce fraying during machine sewing.
Abrasion Resistance: Suitable for projects where seams are exposed to repeated friction, including leather goods, bags and upholstery.
Balanced Strength and Flexibility: Provides the strength needed for durable seams while maintaining enough flexibility for many leather, upholstery and bag-making applications.
