It entirely depends on the brand and model being spoken of. Hook and loop fastener comes in many different flavors.

You see, this is why I am entirely dissatisfied with the current ruling. At best, the rule allows team that manages to find a brand of velcro that is constructed a certain way (or convince their regional inspector that it is so) to have a wildly different functionality available to them than one that cannot.

At worst, the rule allows velcro to only those teams that can somehow manage to manufacture their own velcro.

I understand the GDC's desire not to provide input on certain mechanisms, but there comes a point where in the interest of fairness they must do so.

Re: Help me find evidence to support the use of hook and loop

How about this for the Loop side:

knitted loop material
http://www.rehabmart.com/product/vel...loop-7945.html


Anyone go down to a local fabric store and ask what fabric is easily caught by the Velcro hooks?

"Our problem with Velcro is that its hooks easily grab onto articles of clothing that they were NOT intended for - especially, for example, knit fabrics used for nordic ski suits, and cycling kits. When the hooks brush against the synthetic fibers of polyester, they agitate and pull at them. Even very slight contact with Velcro causes yarn breakage or what we call fabric picking - a process that results in fiber ends that have pulled away from the fabric surface. Ouch!"

Re: Help me find evidence to support the use of hook and loop

Have you tested whether you actually need to add that extra "loopiness" or "hookiness" to the rope side of things? We've been quite surprised at what one can accomplish just on the roller side...

If they were, I suspect that Velcro strap would come apart a lot easier than it does. Pending specific evidence, 3946 is working based on the assumption that those fibers are fused together, so Velcro is out as part of the ROPE. Your assumptions and evidence may vary.
