The details of your problem are rather meager, so if you could comeback with more details about the problem you might get better responses.
I would give RelTek a call to get their recommendations. You might also look at Scotch-Seal Urethane products.
One thing to remember is that is is extremely hard to get a high strength flexible bond on Nylon, that is why you always see components stitched together.
I absolutely agree with Syd...with my experience in bonding and Nylon...thermally fuse or stitch...I usually do both.
Nylon does not bond well, straps will soak it up and if you got something to do the first two, you would bond well but it might tear. Perhaps some sika flex or clear silicone may work, but you need the toughened stuff.
