Embodiment 1
[0016] Attached below figure 1 As shown, the specific implementation process of the nylon belt dyeing method for the needle printer of the present invention is described in detail.
[0017] The main component of the blank nylon tape used in the experiment is PA66. According to the record on page 60 of "Engineering Plastics Handbook" first published by Machinery Industry Press in October 2004, PA66 is a semi-crystalline polymer material with a higher melting point. As long as it is lower than its melting temperature, it It can maintain sufficient rigidity. Compared with general thermoplastic resins, it has a higher operating temperature, higher toughness, and excellent heat resistance, but it has high water absorption. Pure PA66 has a moisture absorption of 8.5% in a saturated state. The equilibrium moisture absorption under 5% RH is 2.5%.
[0018] The experiment uses black ink, its ingredients are carbon black, aniline ink and other pigments and other additives. The pigment par...
Embodiment 2
[0022] Attached figure 2 As shown, this embodiment adds a process step on the basis of the first embodiment, that is, before the blank nylon tape 101 passes through the gap between the two printing rollers 107 and 108, the ink 109 carried on the surface of the printing roller 108 is heated to 30℃~60℃. When the temperature is increased, the ink tank 110 containing the ink 109 is floated in a water tank 113 with a certain amount of tap water, and the ink 109 is heated to a predetermined value by a water bath heating method, so that the ink 109 passes through the ink feed roller 111 and the transfer roller 112 After the two-stage transmission reaches the printing and dyeing roller 108, it still has a temperature of 30°C to 60°C.
[0023] Such as image 3 As shown (the ordinate in the figure represents the reflectivity of printed writing. Reflectivity refers to the ratio of the reflectivity of the object to light and the reflectivity of the standard sample. The abscissa represents t...
