arsenic acid, the principal chemical desiccant used to prepare cotton for harvesting by stripping, is applied to one to two million acres annually in texas and oklahoma. the fate of arsenic residues is of concern to textile processors. cottons containing arsenic were processed into yarn to determine the effects of mechanical processing on residual arsenic content. yarns were wet processed to determine the ease of arsenic removal. arsenic content of yarn was not significantly different from that of the raw stock from which it was produced. arsenic was removed completely from yarn by mild wet treatments indicating that scouring procedures normally used in wet processing would effectively remove residual arsenic.
