Interpretive Summary: Research to develop a process for coating cotton seeds to make them free flowing revealed that gin-run cottonseed contains a significant amount of unginned lint. This paper gives the essential details of a new powered paddle roll saw-type gin stand technology developed that is capable of getting 25 to 40 more pounds of lint from the seed cotton required for a standard bale. This higher lint turnout is produced because of devices added for better control of loading the gin saws and cleaning of the seeds. The new development gives a much higher ginning rate and also about a one half staple length increase compared to a modern high-capacity gin stand. The increased lint turnout gives $13.00 to $25.00 more return per bale for the producer. The average staple length improvement adds an additional $7.50 to the bale value. With an average 17 million bale crop, this adds 350 to 550 million dollars more annual income for US cotton producers.

Technical Abstract: The USDA Agricultural Research Service ginning laboratory in Lubbock, Texas, has an extensive research program underway to develop new saw gin stand technology that promises to substantially benefit cotton producers. Ginning test results show that the experimental gin stand can be configured and operated to produce more lint from seed cotton compared to a conventional high-capacity saw gin stand. Results from fiber tests also have shown that the experimental gin will give better staple length and less short fiber. The changes to the gin stand that make up the powered paddle roll design must be done together or the performance and fiber quality results may be lower than with a conventional saw gin stand.
