  • Title: Botanical trash present in cotton before and after saw-type lint cleaning.
    Author: Morey PR, Bethea RM, Wakelyn PJ, Kirk IW, Kopetzky MT.
    Journal: Am Ind Hyg Assoc J; 1976 Jun; 37(6):321-8. PubMed ID: 937170.
    Abstract:
    The % by weight content of leaf-like, stem, boll, seed, and weed materials sifted (3360 mum greater than particle size greater than or equal to 595 mum) from visible wastes of the Shirley Analyzer was determined for a lint sample taken after ginning but before cleaning and for a second lint sample taken after one stage of saw-type cleaning. The % by weight content for bract and leaf increased with decreasing trash particle size. The content of cotton seed coat fragments decreased with reduction in trash particle size. Approximately 1/4 of the botanical wastes consisted of weed materials, including grass particles. Lint cleaning was ineffective in reducing the % by weight content of leaf-like trash. Some selective removal of stem trash occurred as a function of lint cleaning.
