Description
Tex 70 combines a finer 210D/3 thread profile with measured tensile performance for footwear, leather goods and other professional machine-sewn applications.
Tex 70 (#69 / 210D/3) Bonded Nylon 6.6 Thread
Tex 70 (#69 / 210D/3) bonded nylon 6.6 is a lighter thread size in the NEXUS bonded nylon range. It is especially useful for footwear and other projects where a cleaner, less bulky machine-sewn stitch is preferred over heavier thread sizes.
How Tex 70 (210D/3) Bonded Nylon 6.6 Performs
Tex 70 (210D/3) bonded nylon 6.6 provides a balanced combination of measured tensile strength, flexibility and a finer thread profile for professional machine sewing. Its bonded construction supports stable thread handling, while the smaller thread size helps create a cleaner stitch in footwear, leather goods and similar applications.


Best Applications for Tex 70 Bonded Nylon Thread
- Footwear: A strong choice for shoe uppers, boots and related footwear components where a clean, controlled machine-sewn stitch is important.
- Leather Goods: Suitable for wallets, small leather goods and lighter leather assemblies where heavier thread may look oversized.
- Bags & Accessories: Works well for handbags, pouches, backpacks and similar sewn products that need visible but moderate stitching.
- Automotive & Interior Upholstery: Suitable for many interior upholstery and trim applications where Tex 70 provides the desired stitch size.
- Detailed Machine Sewing: Useful when stitch definition matters but Tex 90 or Tex 135 would create more bulk than the project requires.
How to Use Tex 70 Bonded Nylon Thread
- Machine Setup: Use a machine that can properly handle Tex 70 thread and the material being sewn.
- Needle Size: Start around Size 16–18 / Metric 100–110, then adjust according to the material, machine and stitch result.
- Thread Tension: Adjust upper and bobbin tension gradually until the stitch is balanced and the thread feeds consistently.
- Material Testing: Test the thread, needle and tension on scrap material before sewing the final product.
- Stitch Appearance: Check stitch length and spacing on the actual material, especially when sewing visible footwear or leather seams.


Why Choose Tex 70 Bonded Nylon Thread
- Footwear-Friendly Thread Size: A practical thread profile for shoe construction and visible footwear stitching.
- Cleaner Stitch Appearance: Produces a finer and less bulky seam than heavier Tex sizes.
- Versatile Professional Use: Suitable for footwear, leather goods, bags and upholstery applications.
- Step Below Tex 90: A useful choice when Tex 90 provides more thread bulk than the project requires.
- Measured Performance: NEXUS tensile testing provides real strength, tenacity and elongation data for evaluating Tex 70 performance.
