I’ve found Polygiene a bit hit and miss. I have a mostly white, OR Echo ls shirt with polygiene treatment, and it doesn’t seem to be as effective as some of the other stuff that i have with it. Also, there is the factor that body oils can seep into synthetic fabrics, reducing the effectiveness of such treatments, because the oils can eventually start to cover over the ionic layer. Think a longer, continuous hike, or using a shirt or what not often and not washing ideally.
All synthetics, but especially polyproplyene, polyester, Polygiene, and EPIC type treated fabrics, need to be occasionally “degreased” and you can do this with high ph materials that also alter water tension (Washing Soda etc). This may however, possibly shorten the life of a Polygiene treatment?
If you are a DIY’er type, you can do a Polygiene like home treatment, and if you use copper instead of silver, and use an AC to DC electrical converter, it becomes extremely economical.
What you do is, take a very well cleaned and rinsed piece of clothing, preferably white. Take an AC to DC converter plug that you don’t particularly need (9 to 15 volt output), cut off the plug end, and separate the two connected wires some (half a foot or so). Strip them down some (about an inch). Take some thicker, bare solid copper wire and connect it to the wiring. Tape a little electrical tape over where you connected it.
Get some deionized or preferably distilled water and put it in a large glass jar. Depending on the size of the jar and how much clothing you want to treat, adjust the amount of water and as pure sodium chloride you can get (non iodized etc). If i treat say 2 liters of water, i’ll use about a tablespoon of salt (you want the water to taste noticeably salty, but not overpoweringly so). You probably should pre warm up the water a bit and dissolve the salt in very well before putting it in the jar.
Take the solid copper pieces connected to the wiring, and put them in the water on opposite sides of the jar, making sure they don’t touch the sides or bottom (or each other!). Use some plastic or wood clips to secure the wiring part to the jar. Plug it in to your AC electrical source. Go do other stuff, and depending on how much water and salt you’re treating and how much voltage you’re using (the temp of the water also affects the speed, warmer equals faster), it can take anywhere from a couple hours to half a day to treat.
You’ve just created copper chloride ions. If you used silver, you would have made silver chloride ions. Both are quite antimicrobial and generally safe for contact with the skin.
Get some iDye Poly synthetic dye packets from Joann’s, online, etc. Follow the instructions on the packet to dye your clothes, but use your copper or silver chloride ion infused water for the main water source to dye.
If you dye it right, the copper or silver chloride ions will have bonded with the dye to the surface of the fibers of the clothing you treated. It may not be, and probably isn’t, quite as effective or durable as a true Polygiene treatment, but it will be better and more durable than a lot of the other kinds of treatments out there that add a finish or coating.
Note: Can NOT be used on Polypropylene based fabrics. These don’t accept regular dyes, because the surface energy is too low. You could dip it into the water with the copper/silver chloride, wring it out and let it air dry, and have a very temporary treatment, but key phrase-very temporary.
Unless you know how to do plasma treatment. You could plasma treat the surface of the polypropylene and then dye etc like the above, but that’s way more work and expense than i want to get in.
Doing polyester and nylon the above way i outlined earlier is quite easy, cheap, and really just takes a little time–most of which you can do other things while waiting for the electrolysis process to happen. If using copper and an AC to DC converter, if you dye treat a few articles of clothing at a time, we’re talking cost about a dollar for each piece. Most of the expense is the deionized or distilled water and the few dollars per Dye packet. The copper (or silver) will last a long time before you need to replace it.
Surprisingly, i’ve gotten very little interest here from talking about this DIY home treatment. I would have thought that at least some of the MYOG type folks here would have been all over this, but mostly resounding silence. Perhaps if i sent a piece of treated fabric to Richard N. to have it analyzed, people might become more interested? One could potentially save a lot of money, if having antimicrobial treated, synthetic clothes is important to them. I may make a separate thread about this in the MYOG section.
