Sizing Agents

Compared with conventional surface sizing agents, polymers surface size agents are good film and printing quality. In this work, different types of SMA (Styrene Maleic Anhydride) from the United States Hercules and Sartomer companies were investigated. Firstly, each of SMA sizing agents was studied respectively for choosing the optimized SMA depending on the improvement of physical and ink-jet printing properties, and then the effects of different formulation surface size agents containing the optimum SMA and cationic starch on paper and ink-jet printing properties were also studied in order to analyzing the synergism effects of the two surface size agents. The results show that S520 was better than several other SMA surface sizing agents in the improvement of physical properties and ink-jet printing performance of paper. S520 could produce good film property which could reduce the paper permeability, improve smoothness have less loss whiteness and opacity. It could also enhance the color density, expand the scope of the dark tone and improve dots clarity degree of printed paper.

The era of environmental protection and personalization has become increasingly prominent, and people not only focus on the beauty of the design, but also pay more attention to the quality of the clothing. For inkjet printing, the viscosity and surface tension of ink are major factors that affect the quality of ink-jet printing. In order to obtain a better print quality, the samples of five different viscosity and surface tension of ink were prepared respectively by changing the content of the resin and the surface active agent. Using these samples to print on the fabric by Epson printer, and to discuss the influence of the ink in different viscosity and surface tension on the ink-jet printing quality, such as apparent color depth (K / S), color parameters (L, C), permeability, clarity. The results showed that: with the increase of the ink viscosity, the apparent depth of color yield increased gradually and became darker in color. L value decreased gradually and had a increasing trend, and tends to be stable. C value increased and vividness of the color was improved. And it also had a certain impact on the infiltration resistance and clarity. Surface tension also had a significant impact on the depth of the apparent color, vividness of the color and directly affected the ink permeability and clarity.

With many years of research, color ink-jet printing technology has reached the requirements of color ink-jet printing. The significance of this experiment is to find a suitable method to improve the quality of color ink-jet printing paper. In this work, the dispersion effect and types of sodium polyacrylate (PAAS) on nano-SiO2 solution are discussed, and the most suitable PAAS dosage is selected. When the dosage of PAAS is 8%, the dispersibility of nano-SiO2 solution is much better, with an average color density of 1.60, a gloss of 59% and an ink absorption value of 10.2 cm. Adhesives also have a great influence on color ink-jet printing paper. When the amount of PVA is 30% of nano-SiO2, the average color density is 1.62. Glossiness and ink absorption are also the best.

Fluorescent whitening agent is relatively small dosage in the coating, but it has great influence on the properties of the coating and ink-jet printing qualities. With the increase of fluorescent whitening agent dosage, the PH of the coating rose but the viscosity was hardly to change. The brightness of coated ink-jet printing paper and color density of the printing image firstly presented the trend of increasing then decreasing. What’s more, when the brightness of the coated paper achieved to the maximum, color density and contact angle properties were the largest. Chromatic aberration property of the image reduced from 1.87 to 1.75, when the addition of fluorescent whitening agent rose from 0.1% to 0.5%. While the dosage was rose to 0.9%, chromatic aberration increased to 2.15. The gloss of coated paper decreased with the dosage of fluorescent whitening agent increasing. In sum, fluorescent whitening agent can enhance the brightness of the coated paper as well as the printing properties. The results show that the best brightness and printing qualities of coated ink-jet printing paper are obtained, when the fluorescent whitening agent is 0.5%( relative to pigment).

This paper investigates the possibility of reproducing Braille by UV ink-jet printing on self-adhesive labels, previously printed by flexo printing technol- ogy. The aim was to determine whether it is possible to reproduce Braille, the degree of quality of created Braille dots (cells), the legibility of Braille text, and how many layers of varnish are necessary for quality reproduc- tion. The Braille letter was applied to the previously printed label (design) using 8, 10, 12, 14 and 16 layers of varnish. It has been found that it is possible to reproduce a quality and legible Braille. With the increase in the number of layers, the assessment of legibility and quality of reproduction by the respondents also increased. Samples reproduced with 12 layers of varnish received a very good grade of legibility and good grade for quality of Braille. Samples reproduced with 8 and 10 layers received bad grades for legibility, and even worse for quality, while samples with a higher number of layers of varnish, 14 and 16, received even better grades. The threshold for quality reproduction would therefore be the use of 12 layers of varnish, where a good ratio of workmanship and economy is obtained.

The Way

Piezoelectric Inkjet Printing is the main ink-jet printing at present, and drop state will have great influence to ink-jet printing quality, so the ink-jet drop state of edible ink is researched based on piezoelectric inkjet printing. The viscosity of the ink is adjusted by the way of adding different levels of resin, and then the samples which have different viscosity are got. Drop state is observed through drops observatory which installs Spectra Polaris nozzle (35pl), then the speed, volume, tail length and roundness of the drops are measured at certain moment in order to evaluate the influence of viscosity to ink-jet drop state. The result shows that viscosity has big influence to ink-jet drop state, when the viscosity becomes larger, the speed of drops becomes smaller, the variation of volume is not so obvious, the tail length of drops becomes smaller and roundness becomes larger accordingly, until the viscosity is 10mPa•s, the tail length is the smallest and roundness is the biggest, the drop state is the best , when viscosity is bigger than 10mPa•s, the tail length will become bigger and roundness smaller.

Dye Solutions

Digital inkjet printing has been widely used in textile industry. The quality of dye solutions and ink-jet droplets limits the ink-jet printing performance, which is very important for obtaining high-quality ink-jet printing images on fabrics. In this paper, we introduced diethylene glycol (DEG) into the dye solutions of Reactive Blue 49 and Reactive Orange 13, respectively, and investigated the interaction between dye chromophores and DEG molecules. Results indicated that the dye chromophores were featured in the aggregation. Adding DEG into the dye solution could effectively disaggregate clusters of reactive dyes, and eliminate satellite ink droplets, thus improving the resolution of the ink-jet printing image on fabrics. Under the same DEG concentration, the disaggregation effect was more obvious in Orange 13 than in Reactive Blue 49. Higher DEG concentration was required in Reactive Orange 13 solution for creating complete and stable ink drops. The surface tension and viscosity of the dye solutions were measured, and printing performance on cotton fabrics was evaluated. The interaction mechanism between dye chromophores and DEG molecules was also investigated. Results from this work are useful for high-quality ink-jet printing images on fabrics.
