Hello, this is Kayaba from the ApparelX Insight editorial team.
Today, we would like to introduce sewing threads for leather products in response to customer inquiries.
Bonded Threads for Leather Products
Bonded thread is a commonly used sewing thread for leather products. It undergoes a bonding process, in which the thread is coated with resin, enhancing its heat resistance, abrasion resistance, durability, and weather resistance. The resin bonds the twisted fibers together, preventing fraying and ensuring clean stitches even when sewing thick fabrics or rubber-based materials.
One standout product is Vinymo MBT, which features core bonding technology to prevent fraying. Unlike traditional bonded threads, which may cause machine clogging due to resin peeling, this thread minimizes such issues while maintaining smooth performance. Additionally, its non-fraying nature makes it easier to thread through the needle.
Thanks to its strong hold and minimal fraying, Vinymo MBT ensures beautiful, clean stitches with reduced risk of unraveling or thread slippage after sewing. Even with the complex movements of computerized sewing machines, it maintains high-quality stitching without fraying.
Sewing Threads for Leather Products Available on ApparelX
From here, we will introduce sewing threads for leather products that you can purchase on ApparelX. These threads are specially designed to ensure strong, durable, and high-quality stitching for leather applications.
Stay tuned as we showcase some of the best options available!
KING Polyester Threads (Size #30, #40)

Fujix does not offer bonded threads, but you can use KING Polyester #40 or #30 for sewing leather. These are industrial sewing threads that provide a glossy finish.
While they do not have bonded processing like Vinymo MBT, they offer a wider range of colors, making them a great option for projects requiring color variety and a polished look.
KING Leather Sewing Thread

In addition to KING Polyester, you can also sew leather with KING Leather Sewing Thread.
The main differences between KING Leather Sewing Thread and KING Polyester are:
- KING Leather Sewing Thread is designed for household sewing machines, making it a great option for DIY leather projects.
- It has more fibers and fuzziness compared to KING Span Thread, allowing it to blend better with fabric and create a softer, more natural finish.
If you’re looking for a thread that works well on a domestic sewing machine and provides a natural texture, KING Leather Sewing Thread is a great choice.
Conclusion
We hope this guide has helped you understand the unique features of each sewing thread for leather products.
In addition to sewing threads, we also offer various leather product accessories and parts. Be sure to check out ApparelX for more options!
