18 (a) Scanning electron photomicrograph of a wool fibre. The scales on the surface of the fibre make it easier for it to move in one direction than the other in the yarn structure, leading to felting on washing.


(b) Scanning electron photomicrograph of a wool fivre after coating with Hercosett 57. The scales on the surface of the fibre are masked by the resin, which swells in water preventing preferential fibre movement and hence shrinkage.
