LAYER
3 "Lyrca," invented by Du Pont, is a man-made fiber that has all the elastic qualities of natural rubber. It is stronger than natural elastic thread, but weighs one-third less and wears much longer. "Lycra's" flexibility and strength made it a good choice for a material to hold the cooling tubes close to the astronaut's body. You will find it most often in women's swim suits and undergarments. Taken from a 1970s DuPont poster. |
