Description
Technical Field
The invention belongs to the technical field of yarn processing, and particularly relates to a dyeing process of conductive yarns.
Background
The conductive yarn is used for manufacturing functional textiles with antistatic, electromagnetic shielding and artificial intelligence performances by applying the conductive function of the conductive yarn. The conductive yarn is a functional fiber with conductive performance which is manufactured by the technical means of blending, combining, twisting and the like of conductive fibers and conventional textile fibers.
In the textile field, polyester fiber is a common textile material and has the advantages of high strength, good elasticity, high heat resistance, wear resistance, high light resistance and the like, but polyester fiber fabrics are poor in hygroscopicity, are extremely easy to generate static electricity, are difficult to dissipate, directly influence the production, processing and application of the polyester fiber fabrics, and even cause serious static disasters. To eliminate the static hazard of polyester fibers and fabrics thereof, the fibers are usually required to be treated, for example, a conductive agent is added in the preparation process or blended with metal fibers to improve the conductivity of the fibers or fabrics. However, the polyester fiber is poor in solubility, dyeing property and hygroscopicity, so that the requirements of different fields are difficult to meet.
Disclosure of Invention
The invention aims to provide a dyeing process of conductive yarns, which aims to solve the problem of poor dyeing property of polyester conductive yarns.
The aim of the invention can be achieved by the following technical scheme:
a dyeing process of conductive yarn, comprising the steps of:
firstly, placing conductive yarns into an acrylamide aqueous solution, soaking, taking out, performing argon plasma treatment, and then washing to obtain pretreated conductive yarns;
mixing sodium dodecyl sulfate, aniline and hydrochloric acid solution, adding ethanol aqueous solution for dilution, adding pretreated conductive yarn, then dropwise adding ammonium persulfate aqueous solution, stirring for 5-6h, and washing with alkene sodium hydroxide aqueous solution after stirring to obtain conductive yarn to be dyed; in the prior art, the polyaniline lacks sufficient chemical bond connection with the fiber, so that the fragile polyaniline is easy to fall off from the surface of the fiber, and the defect can be well overcome after the treatment of the method in the invention by treating the fiber surface with argon plasma to induce the grafting of the acrylamide.
Thirdly, treating the conductive yarn to be dyed with 2.5-3% sodium hydroxide aqueous solution for 30min, neutralizing with 3% acetic acid, adding into dye dispersion liquid after neutralizing, and dyeing: dyeing temperature is 85-90 ℃ and dyeing time is 45min.
Further, during the dyeing process: the dye dispersion liquid comprises 2g/L of dye and 1g/L of dispersing agent; the bath ratio is 1:100.
further, the dye is one of disperse blue 2BLN, disperse red 3B and Fu Long Huang SE-2 GL; the dispersing agent is dispersing agent NNO.
Further, the soaking treatment time in the first step is 5-6h, and the soaking temperature is 50-60 ℃.
Further, the mass fraction of the acrylamide solution in the first step is 20-30%.
Further, in the first step, the power is 100-150W, the treatment time is 180-300s, and the discharge pressure is 30Pa in the argon plasma treatment process.
Further, in the second step, the concentration of the hydrochloric acid solution is 2mol/L, and the concentration of the ammonium sulfate aqueous solution is 1mol/L; the dosage ratio of the sodium dodecyl sulfonate, the aniline, the hydrochloric acid solution, the ethanol water solution and the ammonium persulfate is 1g:0.1mol:10mL:100mL:0.1mol.
Further, the conductive yarn is woven from white conductive polyester fibers.
Further, the white conductive polyester fiber is prepared by the following steps:
mixing the amination ATO conductive powder and ammonium polyphosphate aqueous solution, stirring for 2 hours at the temperature of 75 ℃, and cooling to room temperature to obtain flame-retardant conductive powder; the surface of the conductive powder is coated with a layer of ammonium polyphosphate, so that the dispersibility and the flame retardance are improved, a synergistic flame retardant effect can be formed with polyaniline on the surface of the conductive polyester fiber, and the flame retardant requirement is further met;
mixing the flame-retardant conductive powder and the PET slices, setting the temperature to 285 ℃, reacting for 4 hours to obtain conductive master batches, mixing the conductive master batches and the PET slices, carrying out melt spinning, stretching for 5 times at 80 ℃, and carrying out heat setting at 100 ℃ to obtain the white conductive polyester fiber. In order to further improve and enhance the performance of the conductive yarn, the flame-retardant effect of the conductive yarn is enhanced by carrying out flame-retardant treatment on the conductive powder in the conductive polyester fiber, and the treatment is carried out on the premise of not affecting the conductive performance of the conductive yarn.
Further, the mass fraction of the ammonium polyphosphate aqueous solution is 30%, and the dosage mass ratio of the amination ATO conductive powder to the ammonium polyphosphate is 1:2; the mass fraction of the conductive powder in the white conductive polyester fiber is 10-11%.
The invention has the beneficial effects that:
the invention provides a dyeing process of conductive yarn, which is characterized in that acrylamide is induced to graft on the surface of a fiber through argon plasma treatment, then a polyaniline conductive protective layer is formed on the surface of the fiber, and the conductivity of the fiber can be maintained after dyeing. From the molecular composition of terylene, it is composed of short aliphatic hydrocarbon chain, ester group, benzene ring and terminal alcohol hydroxyl. The polyester fiber has extremely poor hydrophilicity because the polyester fiber has no other polar groups except two terminal alcohol hydroxyl groups, and the plasma treatment (improving the hydrophilicity) forms a polyaniline protective layer (maintaining the conductivity) so as to improve the dye-uptake of the conductive yarn and solve the problem of poor dyeing property of the polyester conductive yarn.
In the specific application process of the conductive yarn, the conductive function is primary, the aesthetic property is secondary, the primary function cannot be ensured, and other properties lose the meaning of selecting the conductive yarn, so that the conductive yarn maintains better conductive property and can better exert the service performance of the conductive yarn on the premise of meeting the dyeing property through adjusting the process.

To further determine whether the second treatment would have an effect on the dye uptake and color fastness of the conductive yarn, the following test was performed: wherein, the residual liquid method is adopted to measure the dye-uptake; soaping fastness is referred to GB/T3921.1-1997 "washing fastness for textile color fastness test": run 1; the test results are shown in table 2 below:
TABLE 2
From the results recorded in table 2, the dyeing process of the invention has good dye uptake, probably because polyaniline has a certain adsorptivity, can better adsorb dye molecules, and can better improve dyeing effect by matching with conductive yarn after plasma treatment, and the obtained product has high soaping fastness.
Example 3
