Problems solved by technology

The traditional method is to wash with a lot of water, wasting time and a lot of water and electricity resources, and the effect is not good
On the other hand, because the positive charge of the cotton fabric treated with the cationic modifier has an electrostatic attraction effect on the dye anion, during the dyeing process, the anion of the paint can quickly combine with the modified cotton fabric, resulting in a relatively small dyeing effect in the early stage of dyeing. High dyeing rate, fast-absorbed coating anions cannot be evenly combined with cotton fabrics, resulting in uneven dyeing

Abstract

The invention provides a pigment dyeing method for improving the leveling property and the cloth cover effect. The pigment dyeing method comprises the following steps of pretreatment scouring and bleaching, neutral cellulase polishing, dust removal and wool washing, cationization modification treatment, water washing, pigment dyeing, water washing, fixation, dewatering, drying and setting. The process formula of dust removal and wool washing comprises the following steps of selecting 2-5 g/L of 550, heating to 70-80 DEG C at a heating speed of 2-3 DEG C/min according to a bath ratio of 1: (8-10), keeping the temperature for 20-30 minutes, and then washing with water. The process formula of the cationization modification treatment comprises the following steps of selecting 2 g/L of a modifier DM-2019, performing dyeing at room temperature, heating to 60-70 DEG C at a heating speed of 1-2 DEG C/min according to a test bath ratio is 1: (20-30), keeping the temperature for 20-30 minutes, performing normal-temperature water washing, and performing pigment dyeing. A fabric is uniform in dyeing, bright in color, clear in cloth cover texture, high in fastness, short in process and good in fabric comfort, and a processing technology is reasonable and easy to operate.
