La invención del nailon

The video discusses the evolution of textile fibers, starting with natural fibers like wool, cotton, and silk, which were valued for their properties but had limitations. In 1939, nylon, the first synthetic fiber, was introduced at the World's Fair, revolutionizing fashion with its affordability and durability. Invented by Wallace Carothers, nylon was developed by studying long polymers from petroleum products. Its strength comes from amide groups in its molecular chain, making it ideal for various applications, including parachutes and ropes during World War II, and continues to be used in products like backpacks and bulletproof vests.
