[0002] Dyeing, also known as dyeing and finishing, is not a single operation process, but a comprehensive processing method covering a series of complex processes such as pretreatment, dyeing, printing, finishing and washing. In the textile industry, when various types of textile fabrics are developed for printing and dyeing, printing and dyeing equipment plays an indispensable key role, and its performance directly affects the quality and production efficiency of the final product.

[0003] In the specific dyeing operation link, if the dyeing of nylon fabric is involved, many difficult problems will be encountered. Due to the chemical structure and physical properties of nylon fabric, it is more difficult to color than other ordinary textile fabrics in the dyeing process.
