Analysis on the Technical Processing when Sublimation Printing
Drying temperature After printing the drying process is the key to the printing process if the dryer poor effect, and even appear to take color and osmosis, resulting in blurred contours, and if over dryer will make part of the excessive carbonization of carbonized, carbonized Fiber adhesion in the polyester filament caused by dark spots difficult to remove, affecting the shade of shiny color in the post-processing when the white fabric can still be slightly oxygen bleaching solution, but not on the stained ground, so after the printing machine Drying room temperature control at 85 ℃ -90 ℃, according to the drying effect of drying room to achieve drying and not to the printing of carbonization as well, timely regulation of temperature.
Re-drying process in order to make the printing part of the carbonization of uniform, taking into account the flat screen printing gap production and processing of printed defects can easily lead to drying after drying room varying degrees. Therefore, to reduce the temperature after the drying room in the rolling mill on the re-charcoal to the impact of rotten cotton charcoal effect to determine the speed of speed, to achieve the purpose of uniform carbonization, stable product quality. Burnt-out steamed at 105 ° C and disperse the dye to be baked at 175 ° C to 180 ° C. If the baking process is used, the burnt part will be excessively carbonized to cause whiteness and darkness. In order to deal with this contradiction, we use the printing process to test and found that the dispersion of the dye can also be solid up to 110 ℃ steam for 6 minutes the best conditions for the process.
