Synthetic fibres are chemical fibres made from synthetic, linear polymers of suitable molecular weight and soluble (or fusible) properties, which are spun and shaped and post-treated. In contrast to natural and man-made fibres, the production of synthetic fibres is not restricted by natural conditions. In addition to the general superior performance of chemical fibres, such as high strength, light weight, easy to wash and dry, good elasticity, not afraid of mould and moth, etc., different varieties of synthetic fibres have certain unique properties.

Users are now demanding more and more from digital direct printing, including its versatility, resistance to friction and high colour fastness. The degree of fading of digital direct printing when subjected to external factors (squeezing, rubbing, washing, rain, exposure, impregnation, etc.), such as good colour fastness, makes the textile less likely to lose colour during use.

clothing printing mainly refers to t-shirts, sweatshirts, casual clothing, knitted

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.

Heat transfer inks are a key element in the field of heat transfer technology. In order for heat transfer technology to be compatible with different fabrics, the rheological and printing adaptability of the inks applied to the surface of the paper base must be studied. The transfer of inks that can be transferred to chemical and natural fibre fabrics onto transfer paper and then onto the corresponding fabric. The rheological properties of the thermal transfer inks were analysed and the relationship between the ink and the printability was determined by measuring the ink density and the transfer paper.

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.
