Problems solved by technology

However, high-temperature dyeing not only consumes a lot of energy and increases the cost, but also makes the wool suffer from heat and chemicals, which destroys the excellent natural quality of wool.
The specific manifestations are: (1) weight loss of wool; (2) many disadvantages to downstream processing such as carding, spinning and weaving, such as loose wool dyeing damage will cause reduction in carding output, increase in short fibers, increase in the number of spinning ends, Spinning output decreases, weaving breakage increases, and strength decreases; (3) The product feels rough and yellow

Abstract

The invention relates to a method of low-temperature dyeing for wool, which is characterized by comprising the following steps: adding fully-dissolved acidic dye for wool, acetum with the concentration of 99% and Univadine in an ultrasonic oscillator, and adding distilled water according to the bath ratio of 1:20-80; wetting wool fiber in the distilled water under the temperature of 40 DEG C, wiping, pouring into the ultrasonic oscillator, boosting the temperature at 40-60 DEG C at the speed of 1 DEG C / min, and dyeing for 45-60min, wherein the ultrasonic frequency is 20-50kHz, and the ultrasonic strength is 0.08-1.0W / cm<2> in the dyeing process; taking the wool fiber out after dyeing, washing by cold water and parching. The invention belongs to low-temperature dyeing, does not need additional heat energy in dye bath, can use no or less aid, and is favor of environment protection.

Description

technical field [0001] The invention relates to a low-temperature dyeing method for wool, belonging to the technical field of textile printing and dyeing. Background technique [0002] During the dyeing process of wool, because there is a dense hydrophobic scale layer on the surface of the wool fiber, which hinders the adsorption of the dye to the wool fiber and the diffusion into the interior, the wool is generally dyed at a high temperature of 98°C, which can increase the diffusion rate of the dye. However, high-temperature dyeing not only consumes a lot of energy and increases the cost, but also makes the wool suffer from heat and chemicals, which destroys the excellent natural quality of the wool. The specific manifestations are: (1) weight loss of wool; (2) many disadvantages to downstream processing such as carding, spinning and weaving, such as loose wool dyeing damage will cause reduction in carding output, increase in short fibers, increase in the number of spinning...
