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.

Краски для термопереноса являются ключевым элементом в области технологий теплопередачи. Чтобы технология теплопереноса была совместима с различными тканями, необходимо изучить реологическую и печатную технологичность красок, наносимых на поверхность бумажной основы. Перенос чернил, которые можно переносить с тканей из химических и натуральных волокон, на копировальную бумагу, а затем на соответствующую ткань. Были проанализированы реологические свойства красок для термопереноса, и связь между красками и печатными свойствами была определена путем измерения плотности чернил и бумаги для переноса.

Технологии и оборудование для цифровой трансферной печати теперь доступны повсюду, а на рынке печати на нейлоновых тканях в основном используются трафаретная печать, холодная трансферная печать, цифровая прямая печать распылением и некоторые другие методы. Плоская или круговая трафаретная печать сложна для сложных и деликатных цветных рисунков, и в процессе печати возникает много отходов. Холодная трансферная печать, при которой ткань смачивается и переносится при комнатной температуре, чувствительна к степени влажности ткани во время процесса переноса, и как только степень влажности изменяется во время процесса переноса, разница в цвете часто становится невыносимой. Цифровая прямая струйная печать — направление, в котором работают коллеги по отрасли. Это делается путем струйной печати кислотными красками на проклеенных тканях с последующим испарением паром, стиркой и сушкой.

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.

The study was carried out to address the problems of complex printing processes, high water consumption in post-treatment, high wastewater discharge, poor colour fastness and poor flame retardancy of polyester/nylon decorative printed fabrics.
