D. When used, it is reduced with alkali sulphur, and then oxidized, and an insoluble dye fixed on the fiber is re-formed, and the intermolecular force is combined.

Note:

①a--Na2Co(g/L);b--x%(0.w.f);c--Na2S:dyes=2~1:1;d--Na2So4(5-10g/L);

②The dyes is applied in advance to the commendation(wetting);

③After add dyes,usually heat at 1℃/min,heating to 98-100℃,and then keep the temperature 45-60 min for dyeing.
