Looking for 100% Nylon Rope? Find Out If Your Rope is Really 100% Nylon

Is Your Rope 100% Nylon?

When you’re readying your supplies for a job, you want to make sure that you have high quality materials at hand. Moreover, you want to make sure that the supplies you’ve purchased actually are what the company says they are. Unfortunately, it is common for retailers to label rope nylon when it is in fact a blend or different fibers. The next time you’re looking for nylon rope for a project, make sure that it really is 100% nylon rope.

Is your rope 100% nylon? Here’s how you can be sure:

Your rope might not be 100% nylon

Believe it or not, the rope you’re using may not be 100% nylon. That’s right - many rope companies sell rope marketed as nylon when they are actually a blend of nylon and other fibers, or they may be composed of another material entirely.

The problem is not just that these companies are misrepresenting the product; they are also potentially compromising their customers’ projects. When you purchase a rope that’s labeled nylon, more often than not, it’s because the task at hand requires a rope that’s 100% nylon.

Don’t be misled by product labels, find out if the rope you’re using really is 100% nylon:

The muriatic acid test

The most reliable method for determining if the rope you have is 100% nylon is the muriatic acid test. Here’s how it works:

Muriatic acid, a corrosive hydrochloric acid, will dissolve nylon, but leave other fibers, like polyester or polypropylene, unaffected.

The test is simple. Submerge the rope in question in muriatic acid. Within just a few minutes, if the rope is truly 100% nylon, it will start to dissolve and become discolored. Other ropes will bear no visible changes from the muriatic acid.

If you want to complete this test yourself, remember that muriatic acid is corrosive, and use caution. Use the proper safety gear, in a very well ventilated area and contact your local waste removal company to appropriately dispose of the muriatic acid.

If you don’t want to get your hands dirty by doing the muriatic acid test yourself, no worries. In this video, QNR does it for you, demonstrating that their 100% nylon rope is aptly named and exposing generic ropes for being misleading.

The float test

For a test that’s a little quicker and easier than the muriatic acid test, try the float test.

If the rope in question floats in water, then it is not 100% nylon, as nylon does not float in water. (If the rope does float, this may indicate that it is polypropylene, as that is the fiber’s expected behavior.)

Unfortunately, the float test is not full-proof. While the rope may not float, it is not safe to automatically assume that it is 100% nylon. For instance, the rope could be polyester, as that material also doesn’t float in water. If the rope doesn’t float, there’s also a chance that it is a blend of different fibers and is, therefore, not 100% nylon.

(By the way, for rope enthusiasts who are now wondering if they should also take pains to test if their rope is 100% polypropylene - save your time and effort. Polypropylene is an inexpensive material, so companies rarely misrepresent a rope as 100% polypropylene.)
