Laboratory dyeing or lab dyeing is critical in ensuring color accuracy in polyester fabric dyeing within textile factories. It involves precise sampling, proper equipment usage, and accurate dye preparation. Key equipment includes High-Temperature High-Pressure Lab Dyeing Machines, Glycerin Lab Dyeing Machines, and Infrared Lab Dyeing Machines, each with unique features and usage points.

• High-Temperature High-Pressure Machines: Suitable for polyester dyeing at up to 130°C, requiring careful bath ratio and maintenance for accurate results.
• Glycerin Machines: Operate at high temperatures with larger capacities, emphasizing bath ratio management and glycerol recovery to maintain efficiency.
• Infrared Machines: High automation and consistent temperature control allow for precise and efficient sample dyeing. Proper maintenance, including liquid level checks and component calibration, is essential.

Advantages of Infrared Lab Dyeing Machines:

1. High Automation: Infrared machines allow pre-programming for various dyeing processes, including heating rate, maximum temperature, and holding time, ensuring consistency and precision.
2. Efficiency: They enable simultaneous dyeing of multiple samples (available in 12-cup, 24-cup, and 36-cup models), reducing processing time while maintaining accuracy.
3. Consistent Heating Control: Infrared technology provides even and stable temperature distribution, ensuring uniform dyeing and preventing color variations.
4. Versatility: Capable of accommodating diverse dye types and processes, including custom programming for specialized dyeing requirements.
5. Clean and Safe Operation: The design minimizes spillage and leakage, maintaining a tidy workspace.
6. Durability: High-quality components, multi-cup separation, and safety features enhance the machine’s lifespan and reliability.
7. Improved Dyeing Accuracy: Cup rotation promotes better interaction between the fabric and dye solution, aiding in even color application.
8. Reduced Maintenance Needs: Intelligent temperature control algorithms and advanced designs lower maintenance efforts compared to traditional machines.

Overall, infrared machines are cost-effective in the long term due to their precision, efficiency, and reduced waste, making them ideal for laboratory sample dyeing.
