The invention relates to a method for
dyeing a
yarn containing
cellulose fiber by
reactive dye. In the method, the following processes are carried out on the
yarn which is warped into a beam by a continuous pad
dyeing mode: padding with cationic modified solution,
drying, padding with
staining solution,
drying, baking, washing and
drying, wherein, a drying cylinder is adopted in the baking process for baking in a contact manner, and the
yarn is directly contacted with a high-temperature outer wall of the drying cylinder. By means of the method, continuous pad
dyeing of the yarn containing
cellulose fiber can be carried out by the
reactive dye; the dyeing process has the advantages of relatively low baking temperature, simple baking mode and less broken yarns which are easily handled by an operator; and the adopted dye has the advantages of being free from restriction of K-type
reactive dye, comprehensive color spectrum, wide selection range, simple auxiliaries without salt,
urea and the like, less dye
hydrolysis consumption, low
wastewater chromaticity and stable dyeing quality, and deep, medium and light color can be dyed.
