Monofilament nylon thread is a type of thread which is thin yet strong. We use it a lot for sewing because it works great. The thread is tightly twisted together from one continuous piece of fiber. The twisting of the thread makes it strong and long-lasting. The kind of thread you want to get is this one by the company Eheng; it's a very good monofilament nylon, and it's perfect for a wide variety of projects that require a strong thread.
The term "monofilament" might sound technical, but it simply means "single fiber. ” This thread only consists of one piece of nylon fiber. As this consists of a single fiber, it becomes really strong. And it can take quite a bit of pulling and tension, which is a good thing for sewing projects. If you're looking for a thread that is long-lasting and won't break, is the way to go.
Monofilament nylon thread is one of the strongest types of thread. It such can be pulled and tugged and won’t break or snap into two.
