Hi all. This is my first post on these forums and it's a generic questions/advice thread that applies to anybody who sweats a lot. Please let me know if I should be posting this elsewhere.
I like costumes but I’m not always a fan of wearing them, because I’m a highly exothermic person and I HATE the feeling of sweat drenched clothing. I’m also an enthusiastic dancer and just a few minutes of partying will make me sweat like crazy. Usually I will choose a costume that is pretty skimpy but that really limits my creativity and you can only show up to so many parties without a shirt before you become known as that guy.
One of the costumes I want to wear involves a fur coat (a modified version of the Malkavian costume from "Vampires: Bloodlines"), which is guaranteed to make me sweat in almost any situation. I want to apply some technology to this coat so that the heat doesn’t totally overwhelm me and I can party in relative comfort. After a bit of research I think the best way to do this would be to install battery powered fans into the jacket or to install cooling ice packs (or other phase change materials).
Ice packs and phase change materials (PCM) are an interesting concept that are used for pain management, mascot costumes and industrial workers. It helps if you have a basic understanding of the science behind phase changes: basically most compounds will require a decent amount of thermal energy before they undergo a phase change but this thermal energy does not contribute to temperature change. This is really useful because you can keep a material at the same temperature for long periods of time while absorbing/emitting significant amounts of thermal energy. Water itself is one of the best phase change materials because it has a very high energy requirement for phase change (also known as the “latent heat of fusion/vaporization”). (Phase Changes) The one thing about water that is not ideal is that it has a phase change temperature at 0 degree and 100 degrees (Celsius), and for the sake of comfort you would probably want to maintain a temperature around 10-15 degrees. There are phase change materials that change phases in this temperature range but it does not seems like there aren’t any materials that can retain as much thermal energy as water (ie their latent energy of fusion is smaller).
Most cooling packs last between 1-4 hours but the most promising one I’ve found claims to last 8 hours. https://www.amazon.com/CryoMAX-Cold...p/B001QFZL1G?ref_=bl_dp_s_web_3023415011&th=1. I believe this is a water based material because it freezes close to 0 degrees. I would prefer a product that freezes at 14 degrees but these products seem to only last half as long (which is counter-intuitive because a warmer object loses heat more slowly, but water has an exceptional thermal capacity). Does anybody here have any experience with cooling packs and integrating them into their costumes?
The next concept is to add fans to the clothing items. There are some products on the market made for this but most of those outfits are partially sealed, ie the jacket forms a seal around the waist and all the air escapes out through the collar. (Amazon.com: Customer reviews: Makita DFJ201ZL 18V LXT Lithium-Ion Cordless Fan Jacket, Large) I was wondering if it’s really necessary to have a tight fitting jacket to do this or if I could still get decent cooling from having a fan installed to a loose fitting jacket (such as the fur coat without elastics). I've found a few small battery powered fans on Amazon that appear to be good candidates to be attached to clothing:
I've used these handheld fans before and they're pretty effective but I’m not sure how well they would work when attached to the inside of my jacket. I would put some perforations in the jacket for the air intake but I’m not sure how much would be needed to get decent air flow. There are some kits made for installing fans into your jacket but they are FAAAAR more expensive than just buying the hand-held fans that I linked above. Does anybody have any experience installing fans into their jackets?
