Abstract
By 0 1-0.5% hydrochloric acid scouring, which has been shown to prevent the dis coloration of the amidoximates of partially cyanoethylated cotton fabrics in the previous paper, it was found that the amidoximate hydrochloride salt might be formed. In com parison with unscoured amidoximates, the scoured matertal, even when formaldehyde- cured under noncatalyzed neutral conditions, with or without tension, had exceedingly improved crease resistance without much loss in tensile strength, elongation, and tear strength. The softness of cotton was retained. It was deduced that the amidoximate hydrochloride might presumably split off hydrochloric acid and act as a self-catalyst in the formaldehyde-curing.
