The K/S value of naturally colored green and brown cotton fibers increased after one washing and decreased after additional washings. Scouring increased color depth. Green and brown cotton had poor fastness to hypochlorite reducing agents decreased K/S values. Potassium dichromate reducing agents yielded a reddish tonal effect. Potassium permanganate converted green cotton to a mustard color and brown cotton to a dark coffee brown color. Mordanting did not affect fiber strength or elongation but altered the abrasion resistance of brown cotton fibers and improved the colorfastness of green and brown cotton. 5 refs.
