Problems solved by technology

[0002] Polyester fabrics can be dyed into various conventional dark fabrics according to the existing dyeing process, but if you want to dye special black varieties that can meet the requirements of Arab countries, it is still difficult to use the current conventional dyeing process technology, although people have done it Many attempts have been made such as adjusting the dyeing formula, increasing the dyeing temperature, prolonging the holding time, choosing mixed disperse dyes or increasing the amount of dyes, etc., but the improvement of the blackness of polyester fabrics is still very limited. After dyeing, the fabric is not black and the color is reddish. , looks relatively low-grade, and some black fabrics of composite silk give people a "white" visual effect. Even if the amount of dye is increased to more than 10% of the fabric weight during dyeing, there is no obvious effect. Decrease in fastness and increase in cost

Abstract

The invention discloses a dyeing method of a special black polyester fabric. The dyeing method comprises the following steps: (1) unwinding and sewing; (2) refining and wrinkling, wherein the shrinkage rate of the fabric is 30%-35%; (3) dehydrating and drying; (4) pre-sizing at 250 DEG C for 15 seconds; (5) performing alkali deweighting by alkali rolling and steaming, wherein the alkali deweighting rate of the polyester fabric is 30%; (6) washing; (7) dyeing, namely adding 1 g/L of ricinoleic acid ester sodium sulfate, 1 g/L of hydroxypropyl methyl cellulose, 25 g/L of dispersion black, 3 g/L of disperse turquoise blue, 3 g/L of acetic acid and 4 g/L of accelerating agent composed of dioctyl terephthalate, diethylene glycol dibenzoate, dimethyl terephthalate and ethyl benzoate, which are mixed together, regulating the pH value of the dyeing liquor to 4, dyeing for 2 hours at a temperature of 105 DEG C, and washing the dyed polyester fabric through 3 g/L of acidic reducing agent at 45 DEG C; (8) dehydrating and performing infrared drying; and (9) sizing. The dyeing method disclosed by the invention can be used for dyeing black polyester fabrics with good depth and full colored light.
