Interpretive Summary:

Technical Abstract: The study aimed to compare the effectiveness of two lint cleaners for processing saw-ginned Pima cotton. One was a conventional lint cleaner, while the other was an experimental pneumatic lint cleaner. The study assessed the impact of both cleaners on foreign matter removal and the quality of lint produced. The pneumatic cleaner was tested under different conditions, including varying levels of lint moisture content (5-16%, w.b.), line pressure (40-80 psi), and residence time (15-45 sec). The conventional lint cleaner was operated per the manufacturer's specifications with a lint moisture content of 5% w.b. The quality of lint produced by both cleaners was assessed using the HVI method. The results showed that the pneumatic cleaner's lint quality was mainly affected by the lint moisture content, followed by residence time and pressure. On the other hand, foreign matter removal was more influenced by line pressure and lint moisture. Compared to the conventional lint cleaner, some conditions tested using the pneumatic cleaner yielded better-quality lint in terms of upper half mean length, uniformity index, micronaire, strength, and trash content.
