  • The purpose of this study is to investigate the dyeability of crabyon fiber contained cotton towels after dyeing with gallut. In this study, the colorants of gallnut were extracted with boiling water at 60℃ and 60min. Crabyon, composite fiber of Chitin/Chitosan and cellulose, is manufactured by uniformly blending Chitin/Chitosan and cellulose viscose and extruding the blended viscose into spin-bath. Cotton towels with crabyon fiber dyed with extracted solution from gallnut according to concentration, temperature and time. Crabyon fiber contained cotton towels dyed using gallnut were pre of post-mordanted using Al, Cu, and Fe. The dyeability(K/S) and color characteristics(L*, a*, b*, C, and h(color angle)) of dyed crabyon fiber contained cotton towels were measured by computer color matching machine and photographs. The crabyon fiber composition of cotton towels was conformed by amide peak(-CONH-) of chitin or chitosan of FT-IR spectroscopy. The results obtained were as follows; The amide peak of crabyon fiber contained cotton towels appeared at about 1652 cm−1. The dyeability of crabyon fiber contained cotton towel was increased gradually with increasing concentration of gallnut dyeing solution and saturated at about 150%(o.w.f). The optimum dyeing temperature and dyeing time were 90~100℃ and 80minutes expectively. The crabyon fiber contained cotton towels were dyed reddish yellow by non, Al, and Cu mordanting, reddish blue by Fe mordanting, respectively. The fastness to washing according to concentration of gallnut in and mordanting method indicated good grade result as more than 3~4 degree in all conditions.
