Neps of immature cotton fiber appear as light or white specks in dyed fabric. A pretreatment based on the use of chitosan was investigated with the aim of covering neps. The addition of salt after sorption of chitosan, followed b rinsing, enabled the use of direct or reactive dyes by exhaust dyeing in the same bath. With direct dyes, neps were completely covered, color yield was improved, and deeper shades were obtained. Reactive dyes were not as effective in covering neps. The effects of various aftertreatments on the colorfastness properties of the direct dyed fabrics were also examined. 5 refs.
