The study tries to stress that the transfer printing of polyester textiles can be done using natural colours. Turmeric, alkanet, and rhubarb were the colours utilised. Colour intensity, dye penetration percentage and rapidity characteristics were also evaluated. On polyester fabric, a nanoparticle size disperse dye was applied with an ultrasonic. The colour depth of the prints is greatly increased by nanosized dye particles without adding additional chemicals to the printing paste. The use of nanosized dye particles increases the colours of the prints considerably. San Diego has developed a biotreatment approach for polyester fabrics as a team from the University of California. By combining enzyme and inkjet pretreatment stages in one solution, the researchers achieved a time and energy reduction. They also identified a significant increase in the colours of digitally printed polyester samples. A new study shows a simple way for synthesising new thiazole colours. The dyes are used for printing polyester fabrics and are strong in colour, bright in colour and highly durable. Spectral data confirmed findings (IR,1H-NMR, 13C- and Mass spectra.
