A ribbon digital printing process and system

Abstract

The invention provides a webbing digital printing process and system. The method that an integrated continuous ageing dyeing machine is used in the industry for processing is abandoned, and a non-continuous ageing closed ageing machine is used for ageing of ribbons, so that color brightness and color fastness of the ribbons are greatly improved, and color differences are avoided; the ageing machine is closed, so that the problem that condensed water drops and reduces the quality of the ribbons is reduced, and the production efficiency is greatly improved. Besides, a digital textile printer is improved, and the fading and inconvenient cleaning problems caused due to contact of rollers and printing surfaces of the ribbons are avoided. The invention further provides a matched hanger and a creel device. The staining problem caused by stacking of the ribbons is avoided, the tightness of the ribbons can be adjusted, and the ageing procedure is optimized.

Description

Technical field [0001] The invention relates to a digital printing process and system, in particular to a webbing digital printing process and system. Background technique [0002] The digital printing process of webbing in the prior art usually includes the following steps: bleaching and dyeing → printing slurry → printing machine for digital printing → unwinding → steaming and washing in an integrated continuous steaming, washing, and drying dyeing machine Water, drying. Continuous steaming means that the webbing enters at the beginning of the equipment, is steamed while being transported, and is finally output from the end. The steaming equipment is connected to the outside world. The dyeing machine specifically includes a steaming machine for steaming, an alkali agent tank, a hot water tank for washing water, a fixing oil tank for color fixation, and a dryer. The above-mentioned equipment is connected in sequence, and the webbing is in these equipments. Steaming, washing an...

AI Technical Summary

Problems solved by technology

Since the printing surface of the webbing 10 is in direct contact with the pressure roller and the stationary shaft 04, the color of the printing surface will fade, and the pressure roller and the stationary shaft 04 will be stained, which is difficult to clean, and it is easy to pollute the next batch of webbing, reducing the printing of the webbing pattern definition

[0005] 2. Usually after digital printing, the ribbons are packed into boxes, and the ribbons will inevitably have mutual staining problems due to mutual stacking

[0006] 3. Since the length of the steaming machine is generally only 60 meters, and the steaming time needs at least 20 minutes to make the printing ink show the best effect, and in order to ensure that the steaming time of the webbing in the steaming machine reaches 20 minutes, it needs at least 20 minutes. Set the dyeing machine speed to 3 m / min, but the production efficiency is very low

[0007] 4. Since the speed of the webbing in the steaming machine is only 3 m / min, it is inevitable that condensation water droplets will be generated in the steaming machine. Once the water drops on the webbing, the patterns will bloom and become defects.

[0008] 5. The color intensity of continuous steaming is low and the color fastness is not good; the continuous steaming machine is connected to the outside world, and the temperature / air pressure of the steaming machine is not constant, resulting in color difference between the ribbons
