DB212 Series High Temperature High Pressure Package Dyeing Machine

In today’s textile manufacturing industry, productivity, consistency, and energy efficiency have become the key indicators of competitiveness. As market demand continues to shift toward higher quality dyed yarn, shorter delivery cycles, and lower production costs, traditional dyeing equipment is no longer able to fully meet modern production requirements.

This is why more textile manufacturers are upgrading to high-performance package yarn dyeing machines—equipment designed not only for precise dye penetration and color consistency, but also for smarter resource management and greater operational flexibility.

With advanced circulation systems, intelligent automation, low liquor ratio technology, and compact structural design, the new generation of package dyeing machines is transforming how yarn dyeing is performed across cotton, polyester, nylon, wool, blended yarns, and specialty textile applications.

Designed for Multiple Dyeing Processes

One of the most important advantages of modern package dyeing machines is process adaptability. Different yarn materials and dyeing recipes require different liquor circulation methods to achieve the best dyeing results.

This machine supports two primary dyeing modes:

Air Pad Type

Ideal for precision liquor level control, the air pad system uses accurate pressure sensors to maintain stable dye liquor levels during the dyeing cycle. This design improves process consistency while reducing liquor fluctuation.

Full Flood Type

For applications requiring complete liquor immersion, the full flood system ensures maximum yarn penetration and uniform color development, especially suitable for dense packages or specialty fibers.

By offering both systems, textile mills can easily adapt production according to fiber type, color requirements, and process parameters.

Compact Design That Saves Valuable Factory Space

Factory floor space is a critical production resource. Traditional dyeing systems often require external circulation pipelines and additional auxiliary equipment, increasing installation complexity and occupying valuable production areas.

This package dyeing machine adopts a patented integrated design that combines:

• High-efficiency DBNP circulation pump

• Compact shell-and-tube heat exchanger

• Internal liquor circulation system

Without external circulation piping, the machine can reduce installation footprint by approximately 25%, allowing manufacturers to optimize workshop layout and improve production efficiency.

For factories planning capacity expansion, this compact design provides significant operational flexibility.

Intelligent Heat Exchange for Faster Production Cycles

Heating and cooling efficiency directly impacts dyeing cycle time and production output.

This machine is equipped with a specially designed compact calandria heat exchanger installed externally, delivering highly efficient thermal transfer during both heating and cooling stages.

Under standard operating conditions:

Heating Performance

• From 20°C to 130°C in approximately 30 minutes

• Steam pressure: 0.7 MPa

Cooling Performance

• From 130°C to 80°C in approximately 20 minutes

• Cooling water pressure: 0.3 MPa

Faster thermal response significantly shortens dyeing cycles, increases machine utilization, and improves daily production output.

Variable Frequency Pump Control for Energy Savings

Energy consumption is one of the largest operational costs in dyeing facilities.

The main circulation pump is controlled by an advanced inverter system, allowing:

• Stepless flow regulation

• Process-specific liquor circulation adjustment

• Reduced starting current

• Lower energy consumption during partial loading

By automatically adjusting pump output according to dyeing requirements, manufacturers can achieve stable dyeing quality while reducing electricity consumption.

Continuous Liquor Direction Change Without Pump Shutdown

Uniform dye penetration is essential for high-quality package dyeing. Traditional systems often require pump interruption during flow direction changes, which can create uneven dyeing.

This machine features a patented steady commutation system that allows liquor flow direction to change continuously without stopping the main pump.

Benefits include:

• Increased liquor circulation frequency

• Improved dye penetration

• Better level dyeing performance

• Reduced risk of shade variation

This technology is particularly valuable when dyeing high-density yarn packages.

Low Liquor Ratio for Lower Production Costs

Water and chemical consumption have become major cost considerations in textile processing.

This package dyeing machine operates at an ultra-low liquor ratio of 1:6, delivering significant resource savings.

Operational Benefits:

• Reduced water consumption

• Lower dye and chemical usage

• Reduced steam consumption

• Lower wastewater discharge

• Improved environmental compliance

For large-scale dye houses, these savings can significantly reduce operational costs over time.

lntelligent Automation Simplifies Operation

Modern textile production increasingly demands automation and process consistency.

This machine integrates:

• PLC control system

• Multi-function intelligent computer

• Automatic water filling

• Automatic draining

• Automatic temperature control

• Automatic internal and external circulation switching

• Automatic pressure adjustment

Operators can manage complex dyeing recipes with minimal manual intervention, improving consistency while reducing labor intensity.

Pressure Dewatering Improves Post-Dyeing Efficiency

After dyeing, excess water content in yarn packages often increases drying time and energy consumption.

The optional pressure dewatering system helps:

• Reduce residual moisture content

• Shorten drying cycles

• Improve post-processing efficiency

• Lower drying energy consumption

This is particularly beneficial for large-volume production lines.

Durable Stainless Steel Construction

All metal components in contact with dye liquor are manufactured from high-quality anti-corrosion stainless steel.

This ensures:

• Excellent chemical resistance

• Long service life

• Stable performance at high temperatures

• Easy cleaning and maintenance

Combined with mechanical seal pump systems, the machine offers reliable long-term performance even under continuous industrial operation.

Flexible Capacity for Different Production Needs

This package dyeing machine is available in multiple configurations to suit different factory capacities.

Production capacities range from:

Small and Medium Production

• 24kg

• 36kg

• 54kg

• 108kg

Large Industrial Production

• 486kg

• 810kg

• 1080kg

• 1500kg

• 2010kg

Whether for specialty yarn dyeing or mass textile production, manufacturers can select the configuration that best matches their production goals.

Optional Accessories for Expanded Applications

To meet diverse textile processing requirements, the machine supports various optional configurations:

• Auxiliary heating vessels

• Progressive dosing systems

• Secondary water feeding systems

• Hot draining systems

• Loose fiber carriers

• Hank yarn carriers

• Yarn beam accessories

• Automatic unloading systems

These options provide greater flexibility for different yarn structures and production processes.

The Future of Efficient Yarn Dyeing

As textile manufacturing becomes increasingly focused on sustainability, efficiency, and automation, advanced package yarn dyeing machines are becoming essential production assets.

With features such as:

• Dual dyeing modes

• Low liquor ratio

• Intelligent automation

• Energy-saving inverter control

• Compact installation design

• High-speed thermal exchange

This next-generation package dyeing machine offers textile manufacturers a reliable path toward higher productivity, lower operational costs, and consistent dyeing quality.

For mills aiming to remain competitive in global textile markets, investing in smarter dyeing technology is no longer optional—it is a strategic necessity.
