I'm going to do some experimenting in the near future.
Just read the tags on the clothes I could find, and the shirt my son is wearing like a coat is 100% polyester. The shirt I have on in the pic is 100% cotton.
Various fabrics, all washed in the same detergent, and varying results in "reflectivity" of the IR light. Must be more than just fabric type or detergent brand that is involved????????????
I might add that the fabric texture varies, too. The shirt he has on is a soft fleece and mine is corduroy.
The fleece shirt is white looking, the fleece fanny pack isn't. His cotton t-shirt still looks camo and my cotton jeans aren't reflecting light as bad as my cotton shirt.
I don't have an answer as to why it looks the way it does, but I suspect the answer might be something other than than fabric type or detergent type.
Maybe the manufacturers in China are adding lead to our clothing.
