Put the boiled wax liquid into the heat preservation wax disc, pass the wax liquid into the concave surface of the flower roll with the wax suction roller, heat the inner diameter of the flower roll for heat preservation, and remove the excess wax with a scraper to prevent the printing defects. Pressure wax printing on the back of the cloth first, and then print the front half a week later. At the same time, control the printing, wax printing temperature (145 C), small environment temperature (70 C) of the head of the wax printing machine, and wax printing pressure on the back and front. After printing, refrigerate or water-cooled to normal temperature in time, control the drop of cloth 1000m per box, pad the wooden frame layer to prevent sticking wax, and send dyeing in time.
Because the wax printing method is to print the opposite side first and then the front side, under the action of positive pressure, the wax film on the reverse side extends. In the main pattern anti-printing and dyeing, there are slight differences between the positive and negative sides. After wax removal, the three-dimensional and vivid effect of the main pattern is produced, and then special processing of the wax film will make the main pattern more vivid and full of three-dimensional sense. This is machine printing wax prevention. The charm and value of flower cloth. Nafto dye is used to print the cloth at the designated position according to the design intention to produce wax patterns of different colours. Reactive dyes can also be used, but the colour is slightly lighter. It should be noted that the former is not resistant to reducing gases in the steaming machine, therefore, anti-dyeing salt S should be added to the color paste, while the latter is not resistant to acid gases produced by the Nafto dye and sodium bicarbonate should be added to the color paste. When printing with Nafto/reactive dyes, the first step is to print the chromophore pulp, then cover the chromophore pulp, then print the reactive dyes, and then dry them in time with infrared ray to cool down the fabric. In addition, temperature and humidity should be controlled when long-ring evaporator is used to evaporate, so that the reactive dyes can be fully colored without causing wax sticky cloth and guide rollers.
