Scutching

Scutching is a step in the processing of cotton or the dressing of flax or hemp in preparation for spinning. The scutching process separates the impurities from the raw material, such as the seeds from raw cotton or the straw and woody stem from flax fibers.^[1][2] Scutching can be done by hand or by a machine known as a scutcher. Hand scutching of flax is done with a wooden scutching knife and a small iron scraper. The end products of scutching flax are the long finer flax fibers called line, short coarser fibers called tow, and waste woody matter called shives.^[3]

In the early days of the cotton industry, the raw material was manually beaten with sticks after being placed on a mesh, a process known as willowing or batting. The task was mechanised by the development of machines known as willowers. Scutching machines were introduced in the early 19th century. These processed the raw material into a continuous sheet of cotton wadding known as a lap.^{[citation needed]}
