Some properties of a thickener for preparing inkjet printing ink for nylon carpet

Abstract

The properties of a thickener for nylon carpet inkjet printing are presented in this work. A water-based ink was prepared from polyacrylate-based thickener. The physical and chemical properties of the polyacrylate-based thickener used for preparing the inkjet printing ink, as well as its printing effects on carpet, were investigated. Before printing, the properties of the ink, including its surface tension, electrolyte resistance, storage stability, and percentage removal, were investigated. After printing, the efficiency of coloration of printed carpet and the fastness of printed carpet were studied. The results concerning the surface tension and percentage removal of printing ink show that the polyacrylate-based thickener printing ink is suitable for nylon carpet inkjet printing. Meanwhile, its storage stability and electrolyte resistance make it suitable for printing. The efficiency of coloration of printed carpet and the fastness of printed carpet satisfy the requirements of application at appropriate ink concentration and viscosity.

An Overview of Carpets Printing Using Inkjet Technique

“…This line might be modified to make it more orderly. [8] Different carpet products have different parameters, thus while choosing a fiber, one must be aware of quality criteria as well as other characteristics. The three most significant criteria to consider when choosing the proper fiber staple length, are fiber microns, and luster.…”

“…As a result, the characteristics of polyacrylate-based thickeners must be investigated. [8] Experimental Printing ink formulation with various thickener concentrations Inkjet printing ink was made using various quantities of polyacrylate-based thickener (the polyacrylatebased thickener was prepared by mixing polyacrylate, triethanolamine, and surfactant in proportions of 8:0.8:0.2). A polyacrylate-based thickener liquid was mixed with deionized (DI) water in an 800 ml beaker and stirred with an SDF400 dispersion machine (Shanghai Firefly Energy Technology Co., Ltd, China) to ensure that no thickener stuck to the container wall and that the thickener dispersed evenly in the water.…”

“…Dyes and electrolytes in water are two major electrolytes in printing ink that alter the qualities of the ink. [8] In water-based ink, water quality is critical because mineral elements in the water can form complexes with the thickener, affecting the viscosity and rheological qualities of the ink. [19]…”

Preparation of an associative thickener for digital printing of nylon carpet

“…Digital textile printing has great advantages over conventional printing technologies, such as simplifying the printing operation procedures, reducing production cost, lowering effluent waste, consuming less water and energy and, especially, giving the possibility of producing innovative personalized printing articles (Karanikas et al , 2013). The digitally printed carpets in various patterns can be customized for specific customers and particular decorations (Savvidis et al , 2013; Zhou et al , 2017).…”

“…Technically, thickeners used in digital printing must be stable in the printing paste with a reasonable viscosity, but without flushing as steamed at 100°C. A qualified thickener can help avoid the presence of frostiness on the carpet and increase the brilliance and color strength of the printed patterns (Zhou et al , 2017). Generally, thickeners used for digital printing should possess good pseudoplastic behaviors, which benefit to the dye penetration and the maintenance of the printing mark (El-Wahab et al , 2010).…”
