Experiments were conducted at two commercial gins to study the characteristics and efficiency of flow-through air-type lint cleaners operating under standard field conditions. Overall, one air lint cleaner gave a cleaning efficiency of 12 percent compared to 28 percent for one saw lint cleaner. However, the air-type cleaners caused less fiber damage than the saw-type cleaners. Although textile mills prefer that ginned lint be cleaned at gins with only one saw-type lint cleaner, many gins use two stages of saw lint cleaning to obtain higher grades. The results indicate that air-type lint cleaners may better supplement lint cleaning with only one saw-cylinder lint cleaner and ensure acceptable market return.
