Cotton Yarn: How It's Made Cotton yarn (youtube.com)

The process of turning cotton into yarn is a 48-hour process that involves many machines and techniques. Turning protein fibers into yarn has been a method used for many years, however, over the years there have been new inventions and mechanisms to get the job done. First the cotton comes to the manufacturing place in huge bales that have leaves and twigs still scattered throughout the yarn. A system rolls over the bales of cotton and removes five millimeters of cotton and sends it through a shaft that then into a system that blends the cotton and cleans the cotton. Once the cotton is sent through a second time, the cotton become clean and is ready for production. The cotton then goes through a carting machine that combs out the fibers to make them smooth and less tangled, this machine also discards any fibers that are too short to be used. The fibers then get processed through a coiler that turns the fibers into the first stage yarn called the sliver, which is a thick yarn. The sliver is then run through the drawing machine which lines up the yarn six at a time and stretches it out to form the second stage yarn. The yarn is placed through the roving machine that stretches it and makes the fibers tougher and more durable. The third stage yarn called the roving yarn gets placed onto small spindle then onto industrial spindles with the finalized product that is 13 to 16 times smaller than sliver yarn. 


Reflection:

I did not know that there were so many techniques, machines, and processes that goes into making cotton yarn. The yarn produced to sell to make textiles is held at a high standard and is produced with the intention of being durable and clean for people to use. There are so many innovations today when it comes to producing textiles and shows us how far we come from when we first started using protein fibers to create yarn centuries ago.
