The document summarizes the pre-spinning carding process. It discusses that carding is used to convert tufted fiber material into a single fiber web by passing it between wire points or saw teeth. The objectives of carding are to open fibers individually, remove impurities and dust, disentangle neps, blend and orient fibers, and form slivers. It also describes the basic components and working of a carding machine, which uses cylinders and flats to open fibers that are then formed into slivers.
