Fabric Dyeing and Printing
Published in Tom Cassidy, Parikshit Goswami, Textile and Clothing Design Technology, 2017
The process of making a pattern or design on the fabric surface by using some kinds of dyes or pigments, which causes localized dyeing, is called textile printing. In other words, textile printing is the process of applying color to selected portions of the fabric as per definite patterns or designs. In printed fabrics the color should be physically or chemically bonded with the textile fiber, so that the colors can withstand washing and rubbing. The mechanism of textile printing is similar to dyeing but, in dyeing the target is uniform penetration or spreading of a single color in all directions of the fabric, whereas in printing one or more colors are applied in selected parts of the fabric in sharply defined patterns.
Dyes and their application
Published in Michael Hann, Textile Design, 2020
The major advantages of digital printing compared, for example, to rotary screen printing, include design flexibility (with the ability, for example, to produce large repeat sizes), suitability to short runs, the short time required to switch from one design to another, lower water usage, lower power consumption and lower space requirements. By the end of the second decade of the twenty-first century, the major disadvantage continued to be the relatively high installation price (compared to other textile-printing techniques) and the relatively low speed of output compared to rotary screen-printing methods.

Textile printing is the process of applying color to fabric in definite patterns or designs. In properly printed fabrics the color is bonded with the fiber, so as to resist washing and friction. Textile printing is related to dyeing but in dyeing the whole fabric is uniformly covered with one color, whereas in printing one or more colors are applied in certain parts only, and in sharply defined patterns.
Synthesis of salt-resistant hyperbranched waterborne polyurethane associative thickener and its application in textile printing
Published in The Journal of The Textile Institute, 2023
Textile printing is a method of patterning paints or dyes on the fabrics. To prevent the pattern from bleeding when the printing paste is diluted, it is necessary to use the thickeners to increase the viscosity of printing paste and endow printing paste with stickiness and plasticity (Faisal et al., 2019). Therefore, thickeners are critical to the quality of printed textiles. Because of the necessity of salts (e.g. sodium sulfate, sodium carbonate, sodium bicarbonate, etc.) in many textile printing processes (Yuen et al., 2004), the salt-resistance of the thickeners is of great importance. Before the advent of synthetic thickeners, natural thickeners and modified natural thickeners were widely used in fabric printing (Madhu & Patel, 2016). With the progress of polymer chemistry, anionic polyacrylic acid thickener (APAT) emerged, which is an unsaturated polymer containing carboxyl groups. Generally, APAT is synthesized with acrylic monomers and crosslinking agents using emulsion polymerization, inverse emulsion polymerization or precipitation polymerization (Jassal et al., 2002; Ma et al., 2014). When APAT is not neutralized, the molecular chains of APAT are curly. When APAT is neutralized with alkalis, the molecular chains of APAT are fully extended by electrostatic repulsion and hydrogen bonding. Thereby, a large number of the water molecules are locked, resulting in a significant increase in the viscosity (Hou et al., 2005). APAT possesses excellent thickening ability. However, the development of APAT was hindered due to its poor salt-resistance (Zhu et al., 2014).
The effects of CO2 laser treatment on a digital velvet printing

To choose colorant type, fiber content and the fabric’s ultimate use should be considered, along with which pretreatment is compatible with the fabric and colorant. Textile printing inks are of five main types: reactive dyes, acid dyes, disperse dyes, pigments, and latex inks. They are formulated for compatibility with the inkjet process. Inks must be matched to fabrics considering fabric structure or use and fiber content (Cie, 2015). Reactive dyes inks can be utilized on the widest variety of fiber contents, including cellulosic, protein, and synthetic nylon. They are most efficient for printing on fabrics that are derived from plants and are cellulose-based, like cotton, linen, rayon, hemp, or jute, in which they create bright shades with remarkable colorfastness to washing and light. Pretreatment of fabrics is required before they are printed and steaming, washing, and drying are needed after printing (Lee, 2018).
Digital printing cotton golf apparel for junior girls: a study of prototype development
Published in International Journal of Fashion Design, Technology and Education, 2018
According to Fibre2Fashion (n.d.), today’s consumers appear to be more demanding with specific choices in style, design and colour combinations, and digital fabric printing enables designers to meet consumers’ needs for variety, uniqueness and availability. Digital textile printing allows for more customisation and personalisation in terms of the design and colour flexibility (Savastano, 2016). Dupont stated that cotton is most commonly used for digital printing followed by blends of cotton and polyester because cotton is normally used for good washability (Fibre2Fashion, n.d.). Digital printing technology was used for this study to better meet customers’ aesthetic needs (e.g. junior girls’ preferred colours, patterns, designs) as they interrelate with the expressive needs (e.g. age appropriateness and identity) of female junior golfers.
