Spandex yarn, also known as 'elastic yarn,' is an indispensable component of diapers due to its elastic nature. There are numerous applications for spandex fibers. Firstly, they can be stretched repeatedly and almost fully recover to their original size and shape. Secondly, they are lightweight, soft, and smooth. Additionally, they are easily dyed. They also possess strong elasticity due to their resistance to wear and tear, body oils, sweat, and the harmful effects of cleaning agents. They are compatible with other materials and can be spun together with other types of fibers to create unique fabrics that combine the characteristics of both fibers.
