Abstract

The invention discloses a dyeing method of white bamboo charcoal polyester fiber. The dyeing method comprises a desizing step, a dyeing step, an alkali deweighting step, a reducing and cleaning step and a drying step, wherein the desizing step comprises the steps of preparing a sodium carbonate solution in the concentration of 0.5%-1.2%, adding a detergent in the concentration of 0.5%-1.5%, desizing at the temperature of 80 DEG C-110 DEG C for 30-60 minutes with the bath ratio of 1: 30 and further taking out the fiber and fabric; the dyeing step comprises the step of putting the fiber after desizing into a dyeing jar, wherein the mixture ratio of a dyeing solution is as follows: the mass fraction of a reactive dye is 1%-7%, the mass fraction of glauber salt is 2%-5% and the mass fracture of ammonium sulfate is 0.1%-0.5%. According to the dyeing method of the white bamboo charcoal polyester fiber, disclosed by the invention, the impacts of a dyeing and finishing process on a health care function of bamboo charcoal can be reduced, rate of dye-uptake, color fastness and soft performance of hand feeling are increased, and the defect that the ordinary bamboo charcoal fiber is of gray and black and can not be suitable for demands of market segmentation can be effectively solved.

Description

technical field [0001] The invention relates to a fiber dyeing method, in particular to a white bamboo charcoal polyester fiber dyeing method. 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 products. ...
