The Relative Importance of Fiber Friction and Torsional and Bending Rigidities in Cotton Sliver, Roving, and Yarn

In each stage of cotton processing from carding through yarn, the importance of cotton fiber properties and the interaction of fiber on fiber are complex and not fully understood. This work compares how select fiber and fiber interaction properties of raw stock cotton are altered as temperature and humidity are changed independently. Such comparisons provide the key for determining how fiber-to-fiber friction, fiber rigidities, and fiber breaking tenacity and elongation enter into the cohesive forces of cotton sliver, roving, and yarn.
