Abstract: Card slivers were produced from two Indian cottons of micronaire values 2.7 and 3.1 in a 4th generation card using flat tops of five different wire point densities and spun into 80s and 100s combed yarns. Card sliver neps as well as imperfections in the corresponding yarn samples produced using those slivers were estimated. Conducting trials were also carried out using cylinder wires, flat tops and combing segments of variable density. Cylinder wires of variable density in card reduce sliver and yarn nep content by about 35%. Combing segments with 4 partitions in comber produce slivers and yarns with about 25% lower neps as compared to combing segments of 2 partitions.
