Interpretive Summary: A manufacturer’s modification for saw type lint cleaners was examined for impact on bale quality. The modification to the lint cleaner replaced the grid bars with a wire brush in order to retain more lint during cleaning which would in-turn increase profits for the cotton producers. A study was conducted to determine if the wire brush reduced the quality of the lint in the bale. Yarns were produced from cotton processed on a conventional lint cleaner as well as the modified lint cleaner in order to determine if the modifications affected textile processing of the lint. Although the wire brush retained more non-lint content it also retained more lint than the conventional design. The additional material did not have a detrimental effect on the textile performance of the lint. The new design retained an average of 3.5lbs of lint per bale, providing approximately $2 more value per bale of lint to the producer.

Technical Abstract: Saw type lint cleaners are commonly used to improve the overall quality of ginned lint through the removal of non-lint material and short fibers. A standard saw type lint cleaner is made up of several components: the feed works, saws, and grid bars. Slover Manufacturing (Lamesa, TX) has designed and built a wire brush replacement for the conventional grid bar to improve the efficiency of saw type lint cleaners. A study was conducted to determine the effect of the wire brush on the efficiency of the lint cleaner as well as on the fiber properties of the cleaned lint. Yarns were produced from cottons processed on both a traditional lint cleaner and a lint cleaner equipped with the wire brushes. The effect of the lint by the lint cleaner on yarn quality was also examined.
