Relax Dryer

The relaxed-drying machine utilizes an innovative three-channel mesh belt conveying system, allowing fabrics to be fully relaxed, dried, and pre-shrunk in a completely tension-free, “wavy” state.
Whether it’s delicate knit fabrics, high-stretch fabrics, or special fabrics such as towels, velvet, and coral fleece, it delivers unparalleled fluffy texture, stable weight, and extremely low residual shrinkage, making it the ideal choice for improving fabric quality and winning over high-end markets.

Relax Dryder Working Principle

The relax  dryer carries the fabric on a conveyor belt, allowing it to pass through the drying chamber in a completely relaxed state, utilizing a hot air circulation system for even drying.

1. Feeding and Spreading: The fabric is fed through a fabric feeding device and relaxed guide rollers, and then smoothly spread onto a continuously moving conveyor belt (usually made of polyester or metal mesh).

2. Relaxed Transport: The conveyor belt carries the fabric steadily through the high-temperature drying chamber. Because the fabric “rests” on the conveyor belt, it is not subjected to any longitudinal tension and remains in a relaxed state.

3. Hot Air Drying: Heaters (electric, steam, gas, or thermal oil) in the drying chamber heat the air, and powerful circulating fans force the hot air vertically through the fabric and conveyor belt from top to bottom or bottom to top. This through-flow heating is highly efficient and ensures even heating.

4. Cooling and Output: After drying, the fabric is cooled in a cooling zone and then neatly folded or wound up by a fabric output device.

Your Benifits Of Our Relax Dryer

Revolutionary technology integration for optimal performance

1

Achieve truly tension-free relaxation.

Core technology

Dual feed structure + pneumatic tension control + infrared automatic alignment

  • Three-layer Teflon mesh belt, extending the fabric’s dwell time in the oven by 2 times.
  • Moisture evaporates evenly from the inside out. The fabric completely releases internal stress in a “large wave” dynamic motion.
  • Optional mechanical vibration device to enhance the relaxation effect.
  • 8%-10% ultimate shrinkage rate: The secondary overfeed structure ensures that the fabric enters without any tension, creating the premise for high shrinkage.
  • Pneumatic constant tension control, automatic belt tension, extending service life.
  • Overload rate – 20% to + 80% adjustable accuracy, completely eliminating fabric tension.
  • Compatible with open-width and tubular fabrics, seamless switching.

Stable control of shrinkage rate

The fabric shrinkage rate is precisely controlled at 8-10%.

Suitable fabrics

Fabric quality has improved by 40%.

Technical Specifications & Configuration

Comprehensive technical parameters and optional configurations

1. Intelligent Tensionless Infeed Unit

Core Drive & Control:

  • Variable Frequency Overfeed System: Utilizes a frequency inverter for precise control of the overfeed roller, ensuring a stable and reliable overfeed rate. This guarantees fabric quality consistency right from the source.
  • Independent Variable Frequency Mesh Belts: Each layer of the mesh belt is driven by an independent variable frequency motor, allowing for individual speed adjustment. This enables easy configuration of the fabric’s “wave-like” circulation pattern inside the drying chamber, offering superior flexibility for process adjustments.

Tension & Alignment System:

  • Pneumatic Constant Tension System: The mesh belts are automatically tensioned pneumatically to maintain constant tension without manual intervention. The system automatically releases tension during machine stops, significantly extending the service life of the mesh belts.
  • High-Precision Pneumatic Alignment System: A robust pneumatic alignment system ensures the mesh belts remain on their correct path even during high-speed operation, guaranteeing stable and reliable performance.

2. High-Efficiency & Energy-Saving Drying Unit

Hot Air Circulation System:

  • High-Power Centrifugal Fans: Each drying section is equipped as standard with two 11KW high-power fans, paired with high-strength centrifugal impellers, which increases hot air circulation efficiency by 15-30%.
  • Krantz-Structure Nozzles: Inspired by the German Krantz nozzle design and manufactured with CNC precision, these nozzles ensure uniform airflow penetrates the fabric, enhancing both drying efficiency and fabric hand-feel.
  • Convenient Maintenance Design: The fan motor and impeller can be extracted as a single unit, allowing maintenance and repairs to be performed without entering the high-temperature drying chamber, ensuring safety and convenience.
