Plant trash in linters and willowed picker: materials used in the cotton garnetting industry

First cut linters and willowed picker, used in cotton garnetting, were examined for content of cotton bract an other plant trash. Bract was found to be a minimal contaminant of the trash of first cut linters. A significant amount of bract (about 9% of the trash) was present in willowed picker. Cotton seed hulls, a valuable oil mill by product, contained an insignificant amount of bract trash.
