Shearing is a kind of mechanical finish in which the appearance of the fabric is enhanced by cutting the loops or raised surface to a uniform and even height. The machine may have a spiral blade similar to a grass cutting machine.[1][2] A shearing machine can cut the loop or the pile to a desired level.[3] Shearing was most commonly used to make woollens and worsted materials. It was a part of dry finishing of woollen and worsted goods. Previously, shearing was also a component of gigging or napping; when partially produced goods were exposed to shear in order to improve the impact of gigging or napping, the process was referred to as "cropping".[4][2][5]
