All of these are examples of different kinds of fabrics. Denim, the material used for jeans, is made from cotton, a natural fiber.
Cotton plants grow, and the cotton is harvested from the plants.
Then it is separated from the seeds and made into threads. The threads are then woven into cloth. Denim is different from your cotton shirts in the way that it is woven, which makes it stronger and longer lasting. Before talking about Spandex and polyesters, we should talk about polymers. Polymers are a class of chemicals that are often known as plastics.
