"DACRON" POLYESTER FIBER

"Dacron" is a man-made fiber, used extensively in apparel and home furnishings.  Some of you might be wearing garments made of "Dacron" right now.  In the space suit, four layers of strong yet flexible "Daron" polyester are alternated with five layers of "Mylar" as a kind of insulating "sandwich" to protect the spacemen against heat and cold.
