Saw-Type Lint Cleaner Damage by Machinery Components

Abstract.. Saw-type lint cleaners are commonly used to improve the overall quality of ginned lint by removing foreign matter and less desirable short fiber after ginning. Saw-type lint cleaners discard a certain amount of good lint while removing trash and short fiber from the ginned lint; however the saw-type lint cleaners also inflict damage on some of the remaining lint. Removal of foreign matter improves the leaf grade of the lint and removal of short fibers improves the mean length and overall fiber length distribution of the ginned lint which increases the value and improves the textile processing of the lint. The influence of various components of the saw-type lint cleaner on damage is not clearly understood. This paper describes a lint cleaner which has been modified to allow the effects of individual components to be studied. The effects of the feed works and grid bars have been isolated and studied. A method to quantify the quality of the lint ejected by the lint cleaner has also been examined.
