Problems solved by technology

[0005] Aiming at the problem of the low amount of ink carried by the aforementioned unit color ribbon, the purpose of the present invention is to provide a method for dyeing ink on a nylon belt used in a dot matrix printer. The color ribbon processed by the method can not only increase the amount of ink carried by the unit color ribbon, but also Can still maintain the original physical characteristics of the ribbon

Embodiment 1

[0016] Below in conjunction with accompanying drawing 1, describe in detail the specific implementation process of the nylon tape dyeing ink method of the dot matrix printer of the present invention.

[0017] The main component of the blank nylon belt used in the experiment is PA66. According to the records on page 60 of the "Engineering Plastics Handbook" first published by Machinery Industry Press in October 2004, PA66 is a semi-crystalline polymer material with a relatively high melting point. As long as it is lower than its melting temperature, it It can maintain sufficient rigidity. Compared with ordinary thermoplastic resins, it has a higher service temperature, higher toughness, and excellent heat resistance, but it has high water absorption. The moisture absorption of pure PA66 reaches 8.5% in saturated state. Equilibrium moisture absorption at 5% RH is 2.5%.

[0018] The black ink is used in the experiment, and its components are pigments such as carbon black, anil...

Embodiment 2

[0022] As shown in Figure 2, this embodiment adds a process step on the basis of Embodiment 1, which is to carry the surface of the printing and dyeing roller 108 before the blank nylon belt 101 passes through the gap between the two printing and dyeing rollers 107 and 108. The temperature of the ink 109 is raised to 30°C to 60°C. When specifically heating up, the ink tank 110 that is filled with ink 109 is floated in the tank 113 that has a certain amount of tap water, and the ink 109 is heated to a predetermined value by means of water bath heating, so that the ink 109 passes through the ink delivery 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] As shown in Figure 3 (the ordinate in the figure represents the reflectivity of printed writing. The reflectivity refers to the ratio of the reflectivity of an object to light to the reflectivity of a standard sa...

Abstract

The invention relates to an ink painting method of a needle printer used nylon band, the corresponding nylon band composition adopts PA66, and the paint particle diameter and the viscosity of the ink are respectively 5 to 15 micrometers and 600 to 900 cps. The ink painting method comprises the following steps: firstly the nylon band is heated to 100 to 250 DEG C; then the ink is printed and dyed on the nylon band. The temperature of the ink can also be increased by 30 to 60 DEG C before the nylon band is printed and dyed. The service life of the color band produced through the ink painting method can be remarkably increased.

Description

technical field [0001] The invention relates to an ink dyeing method for a nylon ribbon used in a dot matrix printer, in particular to a dyeing ink method for a nylon ribbon used as a dot matrix printer ribbon substrate. Background technique [0002] Ribbon is a common printing consumable. It is an indispensable printing component of dot matrix printers. From the earliest mechanical impact English printers to later computer dot matrix printers, the coloring carriers used are ribbons. The working principle of the ribbon is to use the dot matrix striker in the head of the dot matrix printer or the letter striker in the English typewriter to hit the ribbon, attach the ink carried on the ribbon to the paper, and finally produce ink on the printing paper. Visually visible printed pattern. The quality of the ribbon has a great influence on the quality of the printed pattern and the service life of the ribbon, and is directly related to the service life of the printing needle. ...
