Textile Engineering: Spinning has been apart of human development starting thousands of years before the Middle Ages. Back then it was very slow and required a lot of work. Then in 1828 Thorp created Ring Spinning. In 1967, Commercial rotor spinning was created. And then in the 1970”s Air-jet and Friction spinning was made popular. Ring-Spinning is one of the oldest methods how making yarn. Yarn is fed through the front dating rolls bby the pigtail guide to the ring. The ring is twirling around the bobbin, so that that yarn is wrapped around the bobbin. The Spindle rail then moves up and down so that the yarn wraps around the bobbin evenly. Rotor-spinning is mostly used for cotton and is up to ten times faster than Ring-spinning. Material is feed through the feed and the open roller individualizes the strands. It is then fed to to the yarn arm through the Fibre Transportation Tube. The Rotor then spins the Yarn around the rolling yarn arm creating yarn. Air-Jet spinning was the next advancement in spinning technology. Material is fed through the spinners to individualize the strands up to the spinning head. Air jets spin the yarn by creating air pressure through a spinning vortex. This weaved yarn is then fed through the spinning head to the winding stage. The winding stage is similar to rotor spinning were the yarn is wound around a yarn arm.
 * 1) Yarn Engineering is most important in the Textile industry, where yarn engineers work with textile engineers and machinery to create the most efficient mill as possible. With the advancement of technology, looms, have become much faster. With this increase in speed engineers must consider the type of yarn they can use. It must be able to withhold higher velocity and acceleration, higher frequency of shed opening and more energetic weaving motions. Also looms are now automatic, so the yarn should minimize the potential machine stoppage that would stop the loom. One way to stop stoppages is weaving in a more ideal condition with  low humidity and temperature.
