Embodiment 1

[0025] A white bamboo charcoal polyester fiber dyeing process includes the following steps: desizing→dyeing→alkali weight reduction→reduction cleaning→taking out and drying.

[0026] In the desizing process, it is made into a sodium carbonate solution with a concentration of 0.8% to obtain a desizing solution; in order to obtain a better desizing effect, add detergent 209 to a concentration of 0.5%, certainly those skilled in the art can clearly know that the net Lotion is not necessary here; adjust the bath ratio to be 1:30, and at a desizing temperature of 80°C, use the desizing solution to process the white bamboo charcoal polyester fiber or fabric for 30 minutes, take out the fiber or fabric, and put it into Dye in the dyeing vat containing the prepared dyeing solution.

[0027] Those skilled in the art should understand that the "concentration" mentioned above and below refers to mass concentration for solids and volume concentration for liquids.

Embodiment 2

[0033] In the desizing process, it is made into a sodium carbonate solution with a concentration of 0.5% to obtain a desizing solution. In order to obtain a better desizing effect, add detergent 207 to a concentration of 0.8%. Of course, those skilled in the art can clearly know that the net Lotion is not necessary here; adjust the bath ratio to be 1:30, and at a desizing temperature of 100°C, use the desizing solution to process the white bamboo charcoal polyester fiber or fabric for 60 minutes, take out the fiber or fabric, and put it into Dye in the dyeing vat containing the prepared dyeing solution.

[0034] Described dyeing solution is the aqueous solution that contains the active red B-2BF dyestuff of concentration 5%, the sodium sulfate of concentration 3%, the ammonium sulfate of concentration 0.1%, the dispersant NNO of concentration 0.1%; Adjust the pH value of dyeing solution to be 5.5, Dyeing was carried out at a temperature of 80° C. for 100 minutes.

Embodiment 3

[0038] In the desizing process, a sodium bicarbonate solution with a concentration of 1% is prepared to obtain a desizing solution, and detergent 209 is added to a concentration of 1.5%; the bath ratio is adjusted to 1:30, and the desizing temperature is 90° C. After the white bamboo charcoal polyester fiber or fiber fabric was treated with the desizing solution for 40 minutes, the fiber or fiber fabric was taken out and put into a dyeing vat equipped with a prepared dyeing solution for dyeing.

[0039] Described dyeing solution is the aqueous solution that contains the reactive yellow B-6GLN dyestuff of concentration 7%, the sodium sulfate of concentration 5%, the ammonium sulfate of concentration 0.3%, the dispersant NNO of concentration 0.2%; Adjust the pH value of dyeing solution to be 6.0, Dyeing was carried out at a temperature of 120° C. for 100 minutes.

[0040] Put the dyed fiber or fabric into the alkali weight reduction tank filled with the prepared alkali weight re...

Abstract

The invention discloses a dyeing method of white bamboo charcoal terylene fiber, and is used for optimizing the dyeing pretreatment, dyeing and soft finishing processes of the terylene fiber. The method comprises the steps as follows: desizing with a desizing solution; feeding to a dyeing solution for dyeing; feeding to an alkali weight reduction solution for alkali weight reduction treatment; feeding to a reduction cleaning solution for reduction cleaning treatment; and taking out, and drying. According to the invention, the white bamboo charcoal terylene fiber has different color systems, the bamboo charcoal function is simultaneously kept, and the hand feeling and the softness of the white bamboo charcoal terylene fiber are better.

Description

technical field [0001] The invention relates to a textile dyeing process, in particular to a dyeing method of white bamboo charcoal polyester fibers. Background technique [0002] Bamboo charcoal fiber is a new type of fiber that is made of nano-scale bamboo charcoal powder (bamboo charcoal micropowder), which is added to the slice melt or spinning solution through a special process, and then spun near the spinneret. Bamboo charcoal fiber and its fabrics have the functions and effects of adsorption and deodorization, antibacterial and anti-mildew, emission of far infrared, negative ions, etc., and are widely favored. At present, bamboo charcoal viscose fiber, bamboo charcoal polyester, bamboo charcoal nylon, bamboo charcoal magnetic fiber, etc. have been developed. However, the natural color of bamboo charcoal in bamboo charcoal fiber is black or gray-black, which makes the bamboo charcoal fiber products appear gray or black, which greatly limits the variety of finished pro...
