Every once in a while you'll get a piece of webbing where you are just not sure what it is.
There are 3 tests you can perform in-house to help you identify what your webbing sample is.
The best part is they are easy, quick and free.
The Float Test
Take a piece of the webbing in question and place it in a container of water.
Polypropylene – floats
Nylon – sinks
Polyester – sinks
The Burn Test
Light a piece of the webbing on fire (carefully!). While in flame observe for the following signs:
Nylon – White Smoke
Polyester – Blackish Smoke
Polypropylene – Shrinks and burns
The Smoke Smell Test
After extinguishing the webbing smell the smoke.
Nylon – Celery-like, fishy odor
Polyester – Oily sooty odor faintly sweet, like sealing wax
Polypropylene – Burning asphalt or paraffin wax
These test are easy to perform and will allow you to identify or at least narrow down your webbing search.
If you need more technical information such as break strength DirecTex has an on-site lab to perform more in-depth tests.
If after performing these simple test you still unsure or need assistance you can always submit a sample of the webbing to DirecTex and we will be glad to identify for you.
