about five times their original length. At this point, the polymer is ready to be formed into threads. The next step in the process is to create threads from the polymer. This is done using one of two spinning processes: filament or spun. The filament spinning process involves twisting the long fibers together to create thread, while the spun process combines shorter lengths of the fiber together. Either of these processes can also combine other materials like cotton or wool to make the mixed media fabric that designers choose to make the clothes that many big-name retailers put on the shelves in stores today.

Machines use polymers to create threads, which are then woven into fabric.
