[0002] The spinning machine twists together many animal and plant fibers to make threads or yarns, which can be used to weave cloth. The earliest spinning machine was very simple and was used in the 14th century. After the 18th century, people invented better spinning machines, which made the textile industry the largest industry. All spinning machines only do two things: first, they aggregate a large number of short fibers into loose cotton threads, and then they pull out the cotton threads little by little and twist them into fine cotton threads. The cotton threads become longer after twisting.
