Changes in Cotton Fiber Surfaces Due to Washing

Abstract

Several "washing" procedures have been applied to harvested cotton fibers in at tempts to remove byssinogenic agents before processing. These procedures included washing at various temperatures, scouring, and bleaching. Microscopical examination, by both transmission electron microscopy and scanning electron microscopy, of cotton fiber surfaces showed a reduction in the number of loose surface particles present. Changes were also observed in the nature of the coatings on the fiber surfaces. Natural coatings appeared to have been removed in some cases, and heavier deposits were found on some surfaces. The nature of these deposits could not be determined since finishes had been added in the final bath of all washing processes.
