Embodiment Construction

[0009] The device of the present invention has a stainless steel dye vat 1, 8-12 transducers 2 are arranged on the bottom surface in the stainless steel dye vat 1, all transducers 2 are connected in parallel by wires, and ultrasonic generator 4 is connected with the transducers 2 by wires 3.

[0010] Step 1: select the warp yarn with cotton content of 60%-70% and fineness of 80tex in the wetting solution with a temperature of 80°C, a concentration of caustic soda of 1.2g / L, and a concentration of penetrant of 1.8g / L Wetting treatment. Next, the wetted warp is washed in water at a temperature of 40°C to 45°C.

[0011] Step 2: first add 70% of its volume of water into the 1500L chemical tank, start the agitator, add caustic soda, penetrant, alcohol and indigo dye in turn, stir for 1 hour, wait for caustic soda, penetrant and indigo dye After fully melting, control the temperature to 40°C, then add sodium hydrosulfite while continuing to stir, and regularly heat to 50°C±1°C for ...

Abstract

The invention relates to a technique for using nanometer material and ultrasonic wave to dye warp yarn into indigo blue, which comprises: wetting, dying, cleaning and drying the warp yarn, the technique is characterized in that the dying process is carried out under the ultrasonic wave effect and under the condition that the nanometer material is added into dyeing solution. A device which is used to execute the technique is provided with a stainless dye vat, wherein 8-12 energy transducers are arranged on the bottom inside the stainless dye vat, and all energy transducers are connected in parallel through a guiding wire and connected with an ultrasonic generator through the guiding wire. The technique of the invention utilizes the chemical activity and the surface effect of the nanometer material to increase the dyeing rate of dye greatly. The cavitation effect of the ultrasonic wave and the peptization of the nanometer material eliminate the aggregate ability of the nanometer material, the dying efficiency and the color fastness are greatly increased, 5-7 dye vats in traditional dying procedures are also saved, thereby the energy is greatly saved, and the pollution is reduced.

Description

technical field [0001] The invention relates to a textile dyeing process, in particular to a process for indigo dyeing of warp yarns with nanomaterials and ultrasonic waves and the device used. Background technique [0002] Traditional indigo dyeing of warp yarn is affected by many factors such as the surface properties of the cloth and the dyeing performance of the dye to the cloth. Since indigo dye is insoluble in water and has no affinity for fibers, it cannot be directly used for dyeing. It must be reduced to a soluble leuco with a reducing agent in an alkaline solution, and then oxidized to an insoluble indigo lake and attached to the yarn. The purpose of dyeing is achieved online. The dyeing process of the leuco indigo is that the leuco is firstly adsorbed on the surface of the fiber, and then diffuses to the inside. The carbonyl group in the dye molecule and the hydroxyl group in the fiber molecule form a hydrogen bond and fix on the fiber. Leuco indigo has low affi...
