The invention discloses a kind of chemical fibre color method, including pre-treatment, pre-setting, coloring, wash, soap, fixation, soft treatment, drying, sizing, winding.Present invention employs staged heat-tinting method, and heating rate of temperature fall is strictly controlled, and coloration time so that fabric firm coloration degree height, uniform coloring, retention of color are good；Reservehao S is added in process is coloured, potential aldehyde radical can largely be improved in cellulosic molecule in chemical-fibres filaments to the destructiveness of dyestuff by adding reservehao S, so that color-tinted product pure color light, the color distortion of coloring is avoided, the reappearance and stability of coloring are more preferable.The chemical-fibres filaments that final production of the present invention goes out its uniform colorings, stably, reappearance is strong, elasticity, soft, degree of staining is firm. |
