Artificial fibres are made by extruding a polymer through a spinneret into a medium where it hardens. All these fibres will be of great length, often kilometers long. With the exception spinning process in textile pdf silk, each of these fibres is short, being only centimetres in length, and each has a rough surface that enables it to bond with similar staples. Artificial fibres can be processed as long fibres or batched and cut so they can be processed like a natural fibre.

In long staple spinning, the process may start with stretch-break of tow, a continuous “rope” of synthetic fiber. In open-end and air-jet spinning, the roving operation is eliminated. The spinning frame winds yarn around a bobbin. Generally, after this step the yarn is wound to a cone for knitting or weaving. The yarn is twisted through the spinning of the bobbin as the carriage moves out, and is rolled onto a cop as the carriage returns. Mule spinning produces a finer thread than ring spinning. Spinning by the mule machine is an intermittent process as the frame advances and returns.

1769 and creates yarn in a continuous process. Ring spinning is slow due to the distance the thread must pass around the ring.

A coat of wire slips were placed around a card, which was then wrapped around a cylinder. Bourn produced a similar patent in the same year. Without the tedious toil of needless hands.
