Oh god. This is a tricky one.

Non-metallic is easy.

The loop side has fibers twisted an/or woven in, just loosely. So I guess that counts.

The hook side, well, if the hooks are made of heavy fibers, it depends all on how they are attached to the backing. If they are woven in, then it's all good.

Either, way, you'll need to find double-sided Velcro or sew two strips back-to-back.
