Interpretive Summary:

Technical Abstract: Experiments were conducted to evaluate the performance of a prototype sawless lint cleaner, named the Multibar Sawless Lint Cleaner (MBSLC), to clean lint from a saw-type gin stand processing upland cotton. The MBSLC varies from a conventional saw-type lint cleaner in that it has pins or spiked-teeth instead of saw teeth wrapped around the lint cleaner cylinder. Initial studies showed promising results of the MBSLC creating less lint waste without adversely impacting fiber quality. Based upon the initial findings, an evaluation into various pin configurations and densities was performed to determine the top design(s) in regards to fiber quality, bale value, and lint waste compared to a conventional saw-type lint cleaner. This study was performed using three varieties of upland cotton that were stripper harvested. One variety was harvested without the use of a field cleaner while the other two varieties were harvested using a field cleaner. The study compared nine different spiked-tooth configurations of the MBSLC to a conventional lint cleaner. Preliminary results indicate there to be several spiked-tooth patterns to be equal to or better than the conventional saw-type lint cleaners in regards to fiber quality and bale value. All spiked-tooth treatments evaluated produced less fiber waste than the saw-type lint cleaner. Data from spinning the fiber into yarn is still being gathered. Once all the data is collected and analyzed, the spiked-tooth designs showing the most promising results will be analyzed in greater depth to determine the optimal design for cleaning upland cotton that has been saw ginned.
