Zusammenfassung: | The invention relates to the technical field of printing and dyeing, in particular to a method for reducing the salt dosage of long-vehicle active short-process dyeing. Comprising the following steps: (1) preparing a fabric, and sewing and guiding the fabric front and back; (2) padding the fabric in reactive dye liquor of industrial salt; (3) padding the dyed fabric in a color fixing solution, and carrying out color fixing in a steaming box at the steaming temperature of 100 DEG C; and (4) washing the steamed fabric with water, washing the fabric with cold water at 25 DEG C once, washing the fabric with hot water at 95 DEG C twice, washing the fabric with warm water at 85 DEG C once, washing the fabric with cold water at 25 DEG C twice, and finally drying the fabric in a drying cylinder. According to the method, the salt is added in the liquefied material dyeing process, the use amount of the salt in the color fixing liquid is reduced, salt waste caused by the solubility problem is solved, the drying process |
