What is Lycra where is found or how is it prepared
Answers
Answer:
Lycra is a brand name for elastane, which is a highly elastic synthetic fabric. Despite having different names, Lycra, spandex, and elastane are all the same material, and these fabrics can stretch to 5-8 times their usual size.
This fabric was originally developed by the DuPont Corporation in the 1950s, but it would not exist if polyurethane had not been invented by IG Farben in the 1930s in Nazi Germany. Polyurethane now represents the base material for a number of different plastics, and the same basic chemical synthesis methods are used to make Lycra that are used to make other polyurethane-based plastics.
