Dyeing and finishing technology of textile fabric

The invention relates to the technical field of dyeing and finishing of textile fabrics and in particular relates to a dyeing and finishing technology of the textile fabric. The dyeing and finishing technology comprises the following specific steps: S1: washing; S2: refining a fabric; S3: carrying out singeing; S4: dyeing; S5: removing formaldehyde; S6: printing; S7: finishing; S8: drying. According to the technical scheme provided by the invention, an early-period washing technology is adopted, so that on one hand, dust in textiles can be cleaned; the textiles are treated through a temperature rising manner through changes of washing temperature, and the textiles are subjected to thermal expansion, so that spinning gaps and holes between the textiles can become loose and the dust is easyto clean; an alkaline washing agent is used, so that the textiles are cleaned and have relatively good clean water performance; different auxiliary agents are used so that the dyed and finished textiles can have good color fi
