Eheng: 138 Bonded Nylon Thread. This is the strongest bonded nylon thread available in stores. It is very strong and made to last a long time, so it is excellent for heavy-duty sewing projects. The thread comes with a special coat to make it strong. That means that when you sew with this thread, the coating makes the thread stick and hold up well under pressure.
Eheng's bonded nylon thread #138 is literally the strongest store bought thread available. This ensures that it is suitable for heavy-duty sewing projects that need a tough and dependable thread. It is treated with a coating so that the thread will not fray easily. As you sew with the needle with this thread, heat from the sewing process activates the coating, which then makes the bond created by the stitch even stronger, locking everything in place.
The 138 bonded nylon thread is also one of the best qualities that can handle very rough conditions. It is very resistant to wear, so it does not breakdown easily even with heavy usage. This thread is also resistant to chemicals, making it an ideal choice for sewing items such as clothing, bags, or luggage that see heavy use. If you’re doing things that may contact harsh chemicals, or even water, this thread will continue to be strong. It is built to weather these challenges so that your projects remain unbroken and functional.
This thread is awesome for heavy-duty sewing projects with materials such as leather, canvas, and denim. These kinds of fabrics can be hard to sew because they can be thick. You are limited to using heavy bonded threads with low needle numbers, but the 138-bonded nylon is strong enough to penetrate a variety of thick cloths without trouble. Things like bags or backpacks or something else that you want to hold up to the rigors of life, need a thread that isn’t going to just break on you. Made of 138 bonded nylon thread, Eheng is just the right thing for those kinds of important jobs — to make sure that everything is stitched together, nothing will fall out.
Eheng 138 bonded nylon thread is super durable. For all these reasons, it is made to withstand breaking or fraying, which makes it suitable for all sorts of sewing applications. You are pulling the thread or twisting it too much during sewing, this thread is stronger and will not give way. Not only is the special coating an aid to strength, but it also extends the life of the thread, so you don’t have to worry about it wearing out and not lasting as long as you thought it would. This allows for you to “set it and forget it” so that you can sew as much as you need without stopping to add additional thread constantly.
Eheng provides 138 bonded nylon thread in many colors and sizes. The great thing about this is that no matter what your sewing project is, you can find the right color, right size where you should go to. Whether your color choice is bright and eye-catching or more neutral and can be a sleeve but Eheng offers a lot of variety in the thread. Further, the thread offers size options, meaning it can be used as a sewing machine thread for smaller projects as well as large-scale projects.
