[0055] The dyeing conditions are: the bath ratio is 1:45, the initial dyeing temperature is adjusted to 40°C, then the temperature is raised to 130°C at a rate of 1°C / min, kept for 40 minutes, and then cooled to 70°C at a rate of 3°C / min.

[0056] Wherein, the leveling agent is obtained as follows:

[0057] (1) N, N-dimethylethanolamine, N-phenyl-2-naphthylamine, triethanolamine, triphenylmethane tri...

Embodiment 3

[0065] Step 1. Desizing the white bamboo charcoal polyester fiber with a desizing enzyme concentration of 5 g / L, a steaming temperature of 110° C., and a steaming time of 55 minutes.

[0066] Step 2, drop the white bamboo charcoal polyester fiber after the desizing treatment in the dyeing solution that contains leveling agent and carry out dyeing process, wherein, the dyeing solution includes that the concentration of reactive dye is 5%, the concentration of sodium sulfate is 2%, and the concentration of ammonium sulfate is 5%. 0.2%, the dispersant concentration is 0.1%, and the pH value is adjusted to 6.0;

[0067] The dyeing conditions are: the bath ratio is 1:50, the initial dyeing temperature is adjusted to 50°C, then the temperature is raised to 140°C at a rate of 2°C / min, kept for 60 minutes, and then cooled to 80°C at a rate of 3°C / min.

[0068] Wherein, the leveling agent is obtained as follows:

[0069] (1) N, N-dimethylethanolamine, N-phenyl-2-naphthylamine, trietha...

Abstract

The invention discloses a white bamboo charcoal fiber dyeing method which includes the steps: (1) desizing white bamboo charcoal polyester fibers by a pad steaming one-bath process; (2) placing the desized white bamboo charcoal polyester fibers into dyeing solution containing leveling agents and dyeing the desized white bamboo charcoal polyester fibers; (3) placing the dyed white bamboo charcoal polyester fibers into alkali-minimization solution for alkali-minimization treatment; (4) placing the white bamboo charcoal polyester fibers after alkali-minimization treatment into reduction cleaningsolution for reduction cleaning treatment and drying. The white bamboo charcoal fiber dyeing method has the advantages that the influence of a dyeing and finishing process on healthcare functions of bamboo charcoals can be decreased, dye-uptake, color fastness and soft hand feel performances are improved, and various dyes can be adopted to obtain fibers and fabrics in different colors.

Description

technical field [0001] The invention belongs to the technical field of dyeing, in particular to a method for dyeing white bamboo charcoal fibers. Background technique [0002] Bamboo charcoal has a loose and porous structure, its molecules are fine and porous, its texture is hard, and it has strong adsorption capacity. It can purify the air, eliminate odors, absorb moisture, prevent mildew, inhibit bacteria and repel insects. It can dehumidify and absorb sweat when in contact with the human body, and promote blood circulation in the human body. And metabolism, relieve fatigue. [0003] In recent years, nano-scale bamboo charcoal powder (bamboo charcoal micropowder) has been selected, added to the slice melt or spinning solution through a special process, and then spun near the spinneret to form a new fiber variety. Due to its high strength, good elasticity, heat resistance, corrosion resistance and low manufacturing cost, polyester fiber is an important variety of synthetic...
