Background
Modern protective articles abandon traditional fabrics represented by polyester fabrics and replace high-strength, flame-retardant, antistatic and other high polymer materials, and the high polymer materials endow the fabrics with special functions of high-strength flame retardance and the like, however, the high polymer materials with the special functions have the defects that the macromolecular structures have high crystallinity and high degree of substitution, and the high polymer materials are difficult to dye or print by the traditional method, and are difficult to endow certain colors, so that the application performance of the high polymer materials with the special functions is limited, and the high polymer materials are particularly used for purposes such as outdoor protection stealth and the like. It can be found that there are very few patents on the printing method of the functional high-strength flame-retardant fabric. Currently available articles such as printing on aramid fabrics only use cationic dyes, wherein the color fastness of the aramid printed with cationic dyes is very low and cannot be adapted to outdoor environments. Therefore, a special printing technology needs to be developed to enable the functional high-strength flame-retardant aramid fiber fabric to be capable of printing dark colors, and the color fastness reaches the national standard so as to be used for outdoor protection.
Disclosure of Invention
The invention aims to provide a printing method for improving the color fastness of aramid high-strength flame-retardant fabric, so that the printed aramid high-strength flame-retardant fabric has good color fastness and can be applied to outdoor protection.
The invention adopts the technical scheme that a printing method for improving the color fastness of aramid high-strength flame-retardant fabric comprises the following specific implementation modes:
step 1, color paste preparation;
step 2, printing patterns on the aramid high-strength flame-retardant fabric by using the color paste prepared in the step 1, and then sequentially drying in a drying room, baking for color development and washing;
and 3, performing functional finishing on the aramid high-strength flame-retardant fabric printed in the step 2.
The present invention is also characterized in that,
the specific implementation of step 1 is as follows:
step 1.1, weighing the following raw materials in percentage by mass: 1-3% of emulsion thickening agent, 1-4% of ink pigment, 0.5-1.5% of penetrating agent, 3-10% of emulsion resin and the balance of water, wherein the sum of the mass percentages of the components is 100%;
step 1.2, preparing color paste by using the raw materials weighed in the step 1.1 according to the following sequence: firstly, mixing an emulsion thickener with emulsion resin, and uniformly stirring to obtain a mixed solution A; then, mixing the ink pigment and the penetrating agent, adding a part of water weighed in the step 1.1 to obtain a mixed solution B, and adding the mixed solution B into the mixed solution A to obtain a mixed solution C; and finally, adding the rest water into the mixed solution C to obtain the color paste.
In the step 1.2, the viscosity of the color paste is 6000-7500 mpa.s.
In step 1.1, the emulsifying thickener is a mixture of any two of synthetic gum, etherified cellulose and polyacrylate in any ratio.
In step 1.1, the ink pigment is a water-soluble pigment with a particle size of 0.2 to 0.5 μm.
In step 1.1, the penetrating agent is any one of hexanediol, glycerol and sodium lauryl sulfate.
In step 1.1, the emulsion resin is a mixture of any two of polyacrylate, organic silicon methacrylate and epoxy resin crosslinking agent in any ratio.
In the step 2, the color paste prepared in the step 1 is adopted to print the pattern of the aramid high-strength flame-retardant fabric on a magnetic rod flat screen printing machine, and after printing, drying in a drying room, baking for color development and washing are sequentially carried out; wherein the drying temperature of the drying room is 90-100 ℃, and the drying time is 3-5 min; baking and coloring at the temperature of 140-160 ℃ for 3-5 min; and the water washing temperature is normal temperature, and the water washing time is 1-3 min.

The printing method has the beneficial effects that the printing method can ensure that the aramid high-strength flame-retardant fabric obtains the printing effects of deep color, high color fastness, soft hand feeling and fresh patterns. The main factor for obtaining the effect is that the network interpenetration effect is generated among the emulsifying thickening agents adopted by the invention, so that the viscosity of the emulsifying thickening agents is reduced by the extrusion of magnetic bars in the printing process, and the emulsifying thickening agents smoothly enter the surface of the fabric; the emulsion particles of the emulsion resin are mutually dispersed in minutes by the action of capillary pressure, so that the minutes are entangled with each other, and the adjacent particles are finally integrated to form a film with an understood structure, thereby firmly adhering the pigment to the surface of the fiber. The high-strength flame-retardant fabric printed by the invention meets the color fastness standard requirement of national standard printed fabrics through the inspection of an inspection mechanism.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention relates to a printing method for improving the color fastness of aramid high-strength flame-retardant fabric, which comprises the following specific implementation modes:
step 1, color paste preparation;
the specific implementation of step 1 is as follows:
step 1.1, weighing the following raw materials in percentage by mass: 1-3% of emulsion thickening agent, 1-4% of ink pigment, 0.5-1.5% of penetrating agent, 3-10% of emulsion resin and the balance of water, wherein the sum of the mass percentages of the components is 100%;
in step 1.1, the emulsifying thickener is a mixture of any two of synthetic gum, etherified cellulose and polyacrylate in any ratio.
In step 1.1, the ink pigment is a water-soluble pigment with a particle size of 0.2 to 0.5 μm.
In step 1.1, the penetrant is any one of hexanediol, glycerin and sodium lauryl sulfate.
In the step 1.1, the emulsion resin is a mixture of any two of triethylamine polyacrylate, organic silicon methacrylate and epoxy resin in any ratio.
Step 1.2, preparing color paste by using the raw materials weighed in the step 1.1 according to the following sequence: firstly, mixing an emulsion thickener with emulsion resin, and uniformly stirring to obtain a mixed solution A; then, mixing the ink pigment and the penetrating agent, adding a part of water weighed in the step 1.1 to obtain a mixed solution B, and adding the mixed solution B into the mixed solution A to obtain a mixed solution C; and finally, adding the rest water into the mixed solution C to obtain the color paste.
In the step 1.2, the viscosity of the color paste is 6000-7500 mpa.s.
In the step 2, the color paste prepared in the step 1 is adopted to print the pattern of the aramid high-strength flame-retardant fabric on a magnetic rod flat screen printing machine, and after printing, drying in a drying room, baking for color development and washing are sequentially carried out; wherein the drying temperature of the drying room is 90-100 ℃, and the drying time is 3-5 min; baking and coloring at the temperature of 140-160 ℃ for 3-5 min; and the water washing temperature is normal temperature, and the water washing time is 1-3 min.
Step 3, performing functional finishing on the aramid high-strength flame-retardant fabric printed in the step 2, and performing soft finishing limit according to requirements, wherein the specific parameter requirements are as follows: the softener is an organic silicon softener, the dosage is 1-3 g/L, and the liquid carrying rate is 60-75%.
The color fastness of the printed fabric is detected according to the color fastness detection standard of the national standard GB/T printing and dyeing cloth.
The high-strength flame-retardant fabric has a compact molecular structure, cannot be combined with fibers by using a conventional printing method, is basically separated from the fibers after being washed, is printed by adopting auxiliary agents such as pigments, emulsion thickeners and the like under a certain using amount and a certain condition, can firmly combine the pigments with the fibers, has color fastness of more than 3-4 levels, and meets the application requirements of the printed fabric.
The rheological property of the color paste is usually expressed by viscosity, and the quality of the rheological property influences the clearness, hand feeling, color depth, color fastness and the like of printed patterns of the fabric. When the color paste is printed, the viscosity of the color paste is reduced under the shearing action of the magnetic rod, which is beneficial for the pigment to be printed on the fabric through the screen printing, so that the viscosity of the color paste needs to be well controlled, as shown in figure 1, and figure 1 shows the influence of the viscosity on the rheological property.
As can be seen from figure 1, the color paste is reduced under the action of shearing force, the shearing force of the viscosity C (10000mpa.s) is reduced, the viscosity B (6000mpa.s) and the viscosity A (7500 mpa.s) are not large, the rheological property of the viscosity C is lower than that of the viscosity A and the viscosity B, the color paste is not easy to print exquisite patterns through a screen with high mesh number, and therefore the viscosity of the color paste selected by the invention is 6000-7500 mpa.s.
The ink pigment is an important component in the printing paste, the fineness and the uniformity of ink pigment particles play an important role in the stability, the level-dyeing property, the tinting strength, the chromatic light and the like of the printing paste, and tables 1 and 2 show that the particle size and the dosage of the ink pigment have influence on the printing color depth and the color fastness.
TABLE 1 influence of ink pigment particle size on printing color depth and color fastness
As can be seen in Table 1, as the particle size increases, the color fastness gradually decreases and the color depth increases. The particle size is preferably 0.2 to 0.5 μm for the reason of analysis. Too large particle size, poor hiding power, poor abrasion resistance, shift of the colored reflected light wavelength to the long direction, reddish color, and dull hue. Generally, the smaller the particle size, the stronger the tinting strength, the too fine particle size, the scattering of incident light, the reduced brilliance and the tendency to penetrate deeply into the fiber, which results in a reduced color yield and the tendency of the coating to agglomerate.
TABLE 2 influence of ink pigment amount on printing color fastness and color depth
Table 2 shows that the increase of the amount of the ink pigment has a certain effect on the color fastness, and the color fastness is reduced with the increase of the amount of the ink pigment, because the color depth of the fabric is not increased even if the amount of the ink pigment is increased after the adsorption of the fabric to the ink pigment is saturated, and the fabric is only adsorbed on the surface of the fabric, when the fabric is rubbed by external force, the adhesive force is broken, and the ink pigment particles are peeled off from the surface of the fabric, so that the color fastness is reduced.
The emulsifying thickener belongs to a high molecular compound, contains a large amount of carboxylic acid groups in molecules, has better water solubility and dispersibility, can form a linear polymer network structure through crosslinking among compounds, can adsorb more free water to achieve the thickening effect, but after the dosage of the emulsifying thickener exceeds a certain value, the viscosity of the emulsion is reduced along with the increase of the dosage of the emulsifying thickener, so the dosage of the emulsifying thickener needs to be proper. Table 3 shows the effect of the amount of emulsifying thickener on the color fastness of printing.
TABLE 3 influence of the amount of emulsion thickener on the color fastness and the color depth of the prints
Table 3 shows that the increase of the amount of the emulsion thickener improves the rubbing fastness, but the increase of the amount decreases the viscosity of the emulsion, and the color fastness does not increase with the increase of the amount, so that the amount of the flower thickener is preferably 1-2%.
Emulsion resins are high molecular polymers, and polymer molecules are entangled with each other and dispersed in a solvent in a molecular state, and the polymer molecules are further entangled with evaporation of the solvent to form a film, which is physically bonded to fibers. Table 4 shows the effect of the amount of emulsion resin on the color fastness of printing.
TABLE 4 influence of emulsion resin dosage on printing color fastness and color depth
The green color in the table is modified, and the previous data is forgotten to be modified when being pasted, and the data is checked and found. Table 4 shows that the color fastness starts to increase and gradually decreases with an increase in the amount of the emulsion resin, because polymer molecules are deposited on the surface of the fibers, resulting in an increase in the thickness of the formed film, and the ability to physically bind to the fibers is reduced, resulting in a decrease in the color fastness. Therefore, the amount of the emulsion resin is preferably about 5%. The reason for the influence of the dosage of the emulsion resin on the color depth value is the same as the previous reason.
After the color paste is printed, in the process of forming the film by the emulsion resin in the color paste, low molecular substances such as an emulsifier and the like migrate to the surface of the emulsion film along with the evaporation of water, and in the process of forming the film by the emulsion resin, the lowest temperature is lower than the temperature, so that emulsion particles lose elasticity, and meanwhile, the emulsion particles have enough hardness to prevent the emulsion resin from forming the film, so that the temperature is very important for the film formation of the emulsion resin. TABLE 5 influence of baking temperature on the print fastnesses
TABLE 5 influence of baking temperature on the color fastness and color depth of the prints
Table 5 shows that the baking temperature is increased, the film forming capability of the emulsion resin is enhanced, the color fastness is increased, the color depth value is also increased, the color fastness and the color depth value are both greatly improved when the baking temperature is higher than 150 ℃, the temperature is continuously increased, the color fastness and the color depth value tend to be stable, and the baking temperature is 160 ℃ for saving energy.
The emulsion resin has a film-forming time, and when the film-forming time is reached, the water evaporation particles deform to start film formation, so that the baking time is also an important parameter for determining the film formation of the emulsion resin. Table 6 shows the effect of the baking time on the fastness of the prints.
TABLE 6 influence of baking time on the color fastness and color depth of the prints
Table 6 shows that when the baking time is increased, both the color fastness and the color depth value are increased, and when a certain time is reached, the color fastness and the color depth value tend to be stable, so that the baking time can be determined to be 3-5 min.
