Research Project: Innovative Methods for Cotton Harvest and Lint Cleaning -Midsouth Studies

Location: Cotton Ginning Laboratory(Stoneville, MS)

2011 Annual Report

1a.Objectives (from AD-416)
The objective of this project is to determine the impact of differences in fiber maturity on ginning and textile processing performance. This research will contribute to a better understanding of the impact of immature fibers on cotton's textile performance. If issues are found, it will demonstrate the need to search for ginning methods to reduce these fibers during the ginning process.

Optimize energy use and management of the entire ginning system including module protection and hauling, seed cotton drying and moisture restoration, seed cotton and lint cleaning, fiber removal, baling, bale handling and protection, seed handling and use, and byproduct production and use.

1b.Approach (from AD-416)
The control treatment will be to harvest, gin, and mill-clean the fiber approximating commercial processing as closely as possible with research equipment. The experimental treatments will use less mature cotton and both more and fewer saw-type lint cleaners at the gin. Conclusions will be based on analysis of advanced fiber information system (AFIS) data of samples taken from the different material streams.

3.Progress Report

To date two cultivars of cotton were grown with half of the cotton defoliated early to obtain cottons with the same planting date and genetics but different maturity levels. Considerable rain occurred just before harvest so the cotton may not have been typical, but the immature cotton showed more damage and lower quality at the mill as expected. Harvest conditions were good the second year but less significant differences were obtained in maturity. Data from the second year has been collected but not yet analyzed. In the third year it appears that significant differences will be obtained in maturity but the cotton has not yet been harvested. This project will document the importance of maturity when mills choose cotton for spinning which will help all producers in more appropriate usage of the available cotton. But the study will more significantly benefit producers with more mature cotton because of the documented advantage of spinning more mature cotton.
