Saw Gin Modifications to Reduce Seedcoat Fragments

S. E. Hughs


 
ABSTRACT

Seed loss and seedcoat-fragment generation and contamination of ginned lint during the ginning process can be a problem with newer, small-seeded cotton varieties. Excessive seed loss means a loss of a valuable gin product. Also, seedcoats in ginned fiber cause textile quality problems during the spinning and weaving process. Tests were conducted on a method of holding the gin saws in the middle of the gap between the ginning ribs and its effect on seed damage and seedcoat-fragment generation. Results indicated that the experimental saw guides significantly reduced seed damage. The guides also decreased the level of seedcoats in the ginned fiber, as indicated by significantly higher quality yarn for the experimental method. Other benefits of the guides included a higher gin turnout and longer fiber. Further tests will be done to further improve and understand the somewhat complex interaction of gin saws, saw guides, and cottonseed at the ginning point.
