From the descriptions in Chapter 2, it should be clear that opened and cleaned or scoured materials arrive at the carding stage in the form of small tufts composed of entangled fibers. We learned in Chapter 1 that the purpose of the carding stage is to disentangle these tufts into a collection of individual fibers, the collection being in the form of a web of fibers, and then to consolidate this collection into a sliver or slubbing of the required count. Cotton or wool tufts fed to the carding stage still contain impurities, which would not be the case for man-made fiber tufts. However, the disentangling of fibers facilitates removal of the impurities.
