With the continuous development of new processes and technologies in textile printing and dyeing, dyeing and finishing equipment is constantly being upgraded. In the industry today, new machines for pretreatment, dyeing, printing and finishing appear continuously. In particular, variable-frequency drive and microcomputer technology have greatly improved machine synchronization. As IT gradually enters the textile dyeing industry, CAD/CAM technology and digital information technology are bringing a new revolution.

Printing and dyeing is a key industry for deep processing, fine processing and added value of textiles, and a comprehensive reflection of the level of the textile industry. It is one of China's traditional industries and an important part of export earnings. However, outdated process technology has resulted in low product grades and added value, which has become a key factor restricting exports.

In current domestic dyeing plants, the factors that most affect dyeing quality include unstable pretreatment, imprecise dosing and uncontrolled dyeing curves. An automatic dye dosing system improves accuracy and repeatability:

1. Dye and auxiliary chemicals are weighed and dosed precisely by the system, eliminating human error.

2. Dosing programs follow a set curve, so the dye uptake rate is stable and level dyeing is achieved.

3. Real-time monitoring records every batch, making quality traceable and reproducible.

For jigger dyeing, connecting the automatic dosing system with the machine PLC keeps liquor ratio, temperature and dosing in sync, which is the key to one-pass success in dyeing.
