RE: Scent-Lok Science Site
OK, I watched this whole thing. As someone said, science can inject a test to obtain desired results. Yes it may work "SOME" but in view of the fact these suits don't have a solid wall of carbon, they're mostly little dots between layers with open spaces between. My problem with their test, and they had to do it this way, is they used a very pure, very volitile substance to obtain their results. The things that were not involved that would be in day to day use that contaminate suits and make them loose their effectiveness. What are these things, NON-Volitile substances given off by the body. Fatty acids(the real stink in body odors)and body oils. They are not volitile enough to be purged from the carbon in any dryer. You'd have to almost catch the fabric on fire to purge fatty acids. They only used one substance and he himself said it's great for testing as it's a very volitile gas. That's why they can get such magical reactivation. Throw in other non-volitile substance, and oil base odor gases, come in contact with bacon cooking or something like that. You aren't going to purge these things with a dryer. They're non volitile, you can't get them out of the carbon, so with each used it would become less effective. Hunt on a couple hot summer or early fall days with high temps, it gets more.
So yes, we've known about carbon for decades. We use it in the drycleaning industry. Carbon holds a lot of junk. We try to purge the carbon in filters of drycleaning fluid to reduce hazardous waste. We'd strip them live steam forced through the filters from inside to out for hours. We would reduce the amount of drycleaning fluid about 50 percent by weight. Each filter contained POUNDS of carbon, not a few grams found in a scent lok type garment. There, I'm done, professor Davidmil is finished. Imonitored months of solvent recovery test from carbon filters at IFI(International Fabricare Institute) Thechemical company I worked for had an affliation with DARCO brand activated carbon.(the worlds best) Maybe if you put on a nice newsuit like these people in the opening video do every month or so you'd be alright. But for the general public, buying a $200 suit every year or so get's expensive. And another bone, scent lok in boots. Give me a break. That's blown the second time you wear them and sweat. I'm not putting a pair of $200 Danner boots in a dryer.
One other point......gases take the path of least resistance just like everything else including us. To assure the carbon works in filtration etc, it is forced through a sealed filter under pressure from the outside in. Much like your oil filter in yourcar works. First the filtered solvents are forced through a paper membrane to filter out solids, then through 2 inches of packed activated carbon. This is usually done with pumps running 20-40 pounds of pressure, not just air waving or the surface. You have an opening in the garment a lot of stink gets out just like it does between the dots of carbon. In drycleaning you also usually had a separate bank of all carbon filters that were packed from top to bottom with nothing but carbon. You needed that as a dye remover boost. And folks, these filters aren't small and depending on the solvent flow required you used any number of them. I've seen machines with 42 filters on them and each filter about the size of a mid size waste basket.
