Interpretive Summary: The responses of many of the fiber quality characteristics of various cottons to gin machinery have been adequately reported. However, as gin machines change the fiber characteristics they remove fibrous waste material which includes some good fiber. This negative response of cotton has not been adequately quantified as a function of different varieties of cotton and growth locations. This study considered the fiber loss from over 25 cottons grown in different years in different locations in the Mississippi Delta. Results of one study indicated that wastes removed by the gin stand from similar cottons ranged from 5 to 18 pounds per bale. Similar values were 6 to 20 pounds for a saw-type lint cleaner. Loss of marketable fiber in the waste reduces profits for farmers. Results clearly indicate a major economic impact that should be investigated further to ascertain the reasons behind such diversity in fiber waste.

Technical Abstract: The material removed by saw-type gin stands and saw-type lint cleaners was investigated in three studies. For Study 1, gin stand waste varied from 5.5 to 17.7 pounds per 500-pound bale whereas lint cleaner waste ranged from 6.4 to 19.3 pounds. For Study 2, gin stand waste ranged from a low of 4.9 pounds for Deltapine 5409 to 11.2 pounds for Suregrow 125. Lint cleaner waste ranged from 11.4 pounds for NuCotn 33 to 18.7 pounds for Deltapine 5409. For Study 3, which included 25 varieties at two growth locations, gin stand waste averaged 4.9 and 7.6 pounds across all varieties. Lint cleaner waste was 18.4 and 18.9 pounds for the two growth locations. The factors that govern the fibrous waste in cotton should be investigated further to determine methods to control factors that cause cotton to produce fibrous waste material.
