Description
Technical Field
The invention relates to a method for improving adhesiveness of MXene-based printing ink on wool fabric, belonging to the technical field of textile printing and dyeing.
Background
The electronic intelligent textile mainly comprises textile materials, electronic components, conductive circuits, a power supply and the like. Wool is used as a natural fiber with good performance, and fabrics made from the wool have many excellent performances such as warmth retention, softness, strong elasticity and the like. However, wool fabrics are insulators and cannot effectively interconnect electronic components, so that the conductivity of the wool fabrics needs to be enhanced for use in the field of electronic intelligent textiles.
Applying conductive ink to the surface of a fleece fabric by screen printing or the like is an effective method for enhancing its conductivity. The MXene has a single-layer or multi-layer sheet structure, shows the conductivity of the metalloid, and can be used as a conductive material in printing ink. In addition, a certain amount of adhesive is added into the conductive printing ink to firmly attach the conductive material to the surface of the wool fabric so as to better meet the use requirement.
The ultraviolet curing adhesive has the advantages of high curing speed, energy conservation, environmental friendliness and the like, and the use of the ultraviolet curing adhesive is attracting more and more attention. The ultraviolet light cured adhesive has the main component of resin prepolymer containing active functional group, such as epoxy acrylate, polyurethane acrylate, polyester acrylate, polyether acrylate, etc. and may be polymerized with photosensitizer to produce water insoluble film. The film forming property of the ultraviolet curing agent is improved, so that the adhesive capability of the conductive printing ink to textiles is enhanced, and the conductive printing ink is always the target of industry researchers.
Disclosure of Invention
The invention adopts tri (2-carboxyethyl) phosphine hydrochloride (TCEP) to modify wool fabric, and prepares conductive printing ink by MXene, ultraviolet light curing resin and the like to print on the modified wool fabric, thereby improving the adhesiveness of the printing ink and the wool fabric and reducing the variation degree of the resistance of the fabric after various treatments.
The invention comprises the following processes: (1) Dissolving TCEP in a mixed solution of ethanol and deionized water in a volume ratio of 1:1 to prepare 40 mmol/L solution, and regulating the pH value to 7; (2) Immersing wool fabric in the prepared TCEP solution, treating the wool fabric at the bath ratio of 1:50 and the temperature of 25 ℃ for 4 h, and drying the wool fabric at the temperature of 60 ℃ after cleaning to obtain modified wool fabric; (3) Mixing MXene and deionized water, performing ultrasonic dispersion for 30min, adding ultraviolet curing resin, a thickener and a photoinitiator, wherein the mass concentration of the substances in a system is respectively 10%, 5%, 6% and 0.4%, and stirring for 10min to obtain conductive printing ink; (4) The conductive ink is applied to the modified wool fabric by adopting a silk screen printing method, then is cured for 20 seconds under an ultraviolet lamp, and finally the fabric is thoroughly dried.
In the modification of wool fabrics, 40 mmol/L TCEP solution is prepared by using ethanol and water in a volume ratio of 1:1, and the pH value of the solution is adjusted to 7. Wool fabric was placed therein and modified by treatment at 25℃with a bath ratio of 1:50, 4 h. TCEP is a kind of high-efficiency mild thiol reducing agent, which can reduce disulfide bonds on wool protein molecular chains into reactive sulfhydryl groups, and has the capability of reacting with light-cured resin under certain conditions. After the modification is completed, the wool fabric is washed and dried at 60 ℃ for standby. Then, the conductive printing ink is prepared by MXene, ultraviolet curing resin, thickener and photoinitiator together. The ultraviolet light curing resin is polyurethane acrylic ester resin sold in the market, the thickener has the function of adjusting the viscosity and rheological property of the printing ink, the printing coating can be finer, and the photoinitiator has the function of initiating the resin to polymerize. Finally, the conductive printing ink is applied to the modified wool fabric by adopting a silk screen printing method, and is cured for 20 seconds under an ultraviolet lamp, mercapto groups on the modified wool participate in film forming reaction of carbon-carbon double bonds in photo-curing resin under the excitation condition of a photoinitiator, so that effective connection between a film layer and the fabric is enhanced, MXene is more tightly and firmly attached, and performances such as moisture resistance, stretching resistance and bending resistance are improved.
Description of the embodiments
The invention is further illustrated by the following examples and comparative examples.
Example 1
(1) Dissolving TCEP in a mixed solution of ethanol and deionized water in a volume ratio of 1:1 to prepare 40 mmol/L solution, and regulating the pH value to 7;
(2) Immersing wool fabric in the prepared TCEP solution, treating the wool fabric at the bath ratio of 1:50 and the temperature of 25 ℃ for 4 h, and drying the wool fabric at the temperature of 60 ℃ after cleaning to obtain modified wool fabric;
(3) Mixing MXene and deionized water, performing ultrasonic dispersion for 30min, adding ultraviolet curing resin, a thickener and a photoinitiator, wherein the mass concentration of the substances in a system is respectively 10%, 5%, 6% and 0.4%, and stirring for 10min to obtain conductive printing ink;
(4) The conductive ink is applied to the modified wool fabric by adopting a silk screen printing method, then is cured for 20 seconds under an ultraviolet lamp, and finally the fabric is thoroughly dried.
Comparative example 1
(1) Mixing MXene and deionized water, performing ultrasonic dispersion for 30min, adding ultraviolet curing resin, a thickener and a photoinitiator, wherein the mass concentration of the substances in a system is respectively 10%, 5%, 6% and 0.4%, and stirring for 10min to obtain conductive printing ink;
(2) The conductive ink was applied to an unmodified wool fabric by screen printing, then cured under uv light for 20s, and finally the fabric was thoroughly dried.
The wool fabrics obtained in examples and comparative examples were subjected to water treatment, acid treatment, alkali treatment, stretching and bending treatment, respectively, and then the fabric resistance was measured, and the change rate of the resistance before the relative treatment was calculated, and the results are shown in table 1 below. The conductive wool fabric obtained by the embodiment of the invention has obviously lower resistance change rate than that of the comparative example, which shows that the method of the invention can effectively improve the adhesion firmness between the MXene-based conductive printing ink and the wool fabric.
