Weaving is an ancient textile art that involves placing two threads, one over, one under, (weft and warp) on a loom and turning them, creating a cloth. Nylon the miracle fiber was patented and introduced to the world in 1938. The first completely new synthetic fiber made by man. It was created by a brilliant scientist, inventor and scholar named Wallace Carothers. In 1931, he left Harvard and was hired by the DuPont Company to work in their research laboratory for the development of artificial materials. They were hoping to replace silk (to compete with China) and gave Carothers the task. He started by mixing three chemicals to form a new fiber, he then created the process of distilling water from the main components in order to remove it from the process, making for stronger fibers. This is how nylon was created. This stimulated ensuing discoveries of an entire new world of manufactured fibers. Soon after textile manufacturers could purchase the fiber for half the price of raw silk. Metallic thread is made from copper, gold or silver.
