The optimal technological condition is that the concentration of the modifying agent is 4 g/l, and NaOH is 6 g/l at liquor ratio of 1∶30 for 60 min. at 85℃.Dyeability include uptake rate and color fastness. Dye-uptake of the modified flax is twice more than that of the unmodified. And their color fastness doesnt fall and some of them raise 0.51 level.展开更多
