What are the commonly used printing technologies in Print Fabrics Textile Convertings?

In the production and processing of textiles, printing technology plays a vital role. The field of Print Fabrics Textile Convertings covers a variety of printing technologies, which not only add colorful patterns and designs to textiles, but also meet the needs of different industries for the appearance and performance of textiles.

1. Screen printing
Screen printing is an ancient and classic printing technology. It uses a screen with patterns or text as a printing plate, squeezes ink onto the screen through a scraper, and then prints it on the textile through the screen. Screen printing has the characteristics of bright colors, clear patterns, washability and wear resistance, and is widely used in clothing, home furnishings, advertising and other fields.

2. Heat transfer printing
Heat transfer printing is a technology that uses heat-sensitive ink and transfer paper to transfer patterns to textiles. This technology is divided into sublimation transfer and hot melt transfer. Sublimation transfer uses the property that certain specific dyes (such as disperse dyes) will directly change from solid to gas (i.e. sublimation) when heated to a certain temperature. When these dyes are printed on transfer paper and heated to the appropriate temperature, they sublimate and transfer to the textile to form a lasting image. Sublimation transfer is usually suitable for synthetic fibers (such as polyester, nylon, etc.) because the molecular structure of these fibers allows dye molecules to penetrate and combine with them. The colors are bright, the patterns are clear, the dye molecules are durable and not easy to fade. However, it is not suitable for natural fibers (such as cotton, linen, silk, etc.) because the molecular structure of natural fibers is tight and it is difficult for dye molecules to penetrate. Hot melt transfer uses thermoplastic inks that soften and flow when heated, so that they can be transferred to textiles. Unlike sublimation transfer, hot melt transfer does not involve the sublimation process of the dye, but uses the viscosity and fluidity of the ink to achieve the transfer of the pattern. Hot melt transfer can be used for a variety of textiles, including synthetic fibers and natural fibers. It is suitable for a variety of fiber materials and is relatively simple to operate. Compared with sublimation transfer, the pattern of hot melt transfer may not be bright enough, and the washability and wear resistance may be slightly worse.

3. Digital printing
With the rapid development of digital technology, digital printing technology has gradually emerged. Digital printing uses a computer to control an inkjet printer to directly print patterns onto textiles. This technology has the advantages of high precision, high speed, and high flexibility, and can achieve personalized, mass-produced, and rapid production. Digital printing technology is not only applicable to flat textiles, but can also be applied to three-dimensional textiles and curved textiles, bringing more possibilities to textile design.

4. Lithography
Lithography is a traditional printing technology that transfers patterns to textiles by contacting patterns and texts on the printing plate with textiles and using the interaction of ink and water. Lithography has the advantages of stable color, clear patterns, and low cost, and is widely used in the printing and processing of various textiles.

5. Letterpress printing
Letterpress printing is a technology that uses raised printing plates for printing. The patterns and texts on the letterpress printing plate are raised, and the patterns are transferred to textiles through the action of pressure and ink. Letterpress printing has the characteristics of three-dimensional patterns, rich colors, and good durability, and is often used in the printing and processing of high-end textiles and gifts.
