The traditional printing methods used in printing and dyeing industry are reactive dyes, disperse dyes, acid dyes and coating direct printing; among them, reactive dyes, disperse dyes and acid dyes printing are commonly used by the majority of printing and dyeing manufacturers because of their printing patterns with bright colors, full colors, soft fabric feel and clear pattern outline; many foreign trade orders also add some special requirements, such as chlorine bleaching resistance, oxygen bleaching resistance, dry cleaning resistance, etc.. Therefore, we must use the latest technical means to adapt to the requirements of the market, otherwise a very passive situation will be formed and the development of the industry will be hindered. In this case, people will naturally think of non-polluting or less polluting printing method a coating printing.

In order to combine the traditional Chinese tie-dye technique with digital printing technology for textile and clothing, and to design modern digital printing patterns that match the corresponding characteristics of tie-dye, the advantages, disadvantages and the need to combine tie-dye and digital printing are analysed. The advantages, disadvantages and necessity of combining tie-dye and digital printing at this stage are analysed, as well as the significance and development prospects of combining the two techniques. The innovative combination of digital printing and traditional tie-dye techniques is used in apparel, home textiles and fabrics. This combination will, to a certain extent, open up a new aesthetic market and promote the development of digital printing and traditional tie-dye techniques, providing a reference for innovative product development.

Las tintas de transferencia de calor son un elemento clave en el campo de la tecnología de transferencia de calor. Para que la tecnología de transferencia de calor sea compatible con diferentes tejidos, se debe estudiar la adaptabilidad reológica y de impresión de las tintas aplicadas a la superficie de la base del papel. La transferencia de tintas que se pueden transferir a tejidos de fibras naturales y químicas sobre papel de transferencia y luego sobre el tejido correspondiente. Se analizaron las propiedades reológicas de las tintas de transferencia térmica y se determinó la relación entre la tinta y la imprimibilidad midiendo la densidad de la tinta y el papel de transferencia.

The digital transfer printing technology and equipment is now available everywhere, and the market for nylon fabric printing mainly uses screen printing, cold transfer printing, digital direct spray printing and several other methods. Flat or circular screen printing is difficult for complex and delicate colour patterns, and there is a lot of effluent in the printing process. Cold transfer printing, which involves wetting the fabric and transferring it at room temperature, is sensitive to the degree of wetness of the fabric during the transfer process and once the degree of wetness changes during the transfer process, the colour difference is often intolerable. Digital direct-jet printing is the direction in which industry colleagues are working. This is done by ink-jet printing acidic inks on sized fabrics, followed by steam evaporation and washing and drying.

The textile printing market is rapidly going digital and is receiving great attention. Because this is a world in high demand for digital printing, printing can also become pictures of local Chinese producers, and the number is not large. In addition, digital printing can greatly increase water consumption, so many companies use digital printing technology to recycle digital Printing Technology.

Textile digital printing is developing rapidly in China, many textile digital printing machine manufacturers are transformed from the advertising industry, but textile printing is very different from advertising printing, machine manufacturers lack printing and dyeing technology, and many machines are difficult to sell. The ink of digital printing is different from dyes, and there are more factors affecting the quality of textile digital fabrics than traditional printing, which will also bring difficulties to the promotion of ink.

A digital printing equipment company first of all to understand is to do what kind of products, and then determine the process, and then select the printhead, and then according to the process and the characteristics of the printhead design and manufacturing equipment, after 50,000-100,000 meters of actual production tests, so that the equipment is the digital printing equipment to withstand the scrutiny.

As people’s material living standards continue to improve, the pursuit of a comfortable and elegant home environment has become a fashion. The increasing diversity and individuality of home decoration requires more colourful decorative fabrics, and heat transfer printing products can meet this demand. The introduction of printing to the textile industry has played a very important role. Heat transfer printing is an extension of printing technology in the textile industry. The uneven surface of the fabric, with its numerous pores, makes it difficult to achieve a high level of detail compared to paper printing. Heat transfer printing is therefore a process whereby ink is printed on paper and the fabric is then subjected to a certain temperature and pressure and the dye on the paper is pressurised, heated and sublimated to transfer the pattern from the paper to the fabric. This is a revolutionary change in the textile industry, reducing costs, saving energy and achieving a green, low-carbon production process.

This paper briefly introduces the basic structure, use and maintenance of digital printing machine, the principle of digital printing, the method of image processing, the selection of printing paste and the preparation requirements of fabric, the selection of printing process, the operation technology of printing, and the post-treatment method of fabric after printing. The printing process for cotton, silk, nylon and polyester fabrics is introduced.

El estudio se llevó a cabo para abordar los problemas de los procesos de impresión complejos, el alto consumo de agua en el postratamiento, la alta descarga de aguas residuales, la mala solidez del color y la mala resistencia a la llama de las telas estampadas decorativas de poliéster/nylon.
