We report on the characteristics of two sorts of neps from wet and dry air-jet textured yams and the effects of process variables on their formation. We discuss structural configurations and opening forces using both machine and videographic methods. Wet texturing produces fewer neps at all pressures, but yet counL does increase with increasing pressure, whether the process is wet or dry.
