Interpretive Summary: Opening and carding of fibers is the first processing step for the conversion of cotton and other fibers into finished textile goods. The role of opening and carding is well understood in traditional textile processing for the production of spun yarns and subsequent woven or knitted goods. The impact of these operations is no less important for the nonwovens industry, although it is less well understood by the industry. This report is focused at relating how a traditional opening and carding line can be best utilized by the nonwovens industry. The role of novel carding systems, designed specifically for the nonwoven industry is also discussed, as is the consideration of final product and application in choosing the appropriate opening and carding processes.

Technical Abstract: The opening and carding of fibers is well understood for yarn production. The same operations may also serve a role in nonwoven applications. The presentation is intended as an overview of the options and parameters involved in the opening, cleaning, and carding of fibers, particularly cotton, for those involved in nonwovens production. The proper opening and cleaning of fibers is an essential step in processing. The objective during these stages of processing is to sufficiently prepare the fibers while imparting minimal damage and providing maximum removal of non-lint content. Various parameters such as type and number of opening and cleaning machines, type of carding machine, and environmental conditions all serve a role in determining the final properties of the fiber for further processing into nonwoven materials.
