The GBM beam dyeing machine for elastic fabric supports both unidirectional and bidirectional flow modes to meet diverse fabric processing requirements, offering flexible process adaptability. This equipment provides high-quality dyeing treatment for various high-end fabrics, achieving advanced dyeing standards.
Working Principle
Main autoclave tank
Integral 316L stainless steel pressure vessel, air cushion pressurization design to stabilize internal pressure during elastic fabric dyeing.
Circulation pump with frequency inverter
Stepless adjust liquor flow according to fabric stretch degree, adapt soft thin elastic cloth and thick heavy stretch fabrics separately.
High-efficiency external heat exchanger
Indirect steam/electric heating, rapid temperature rise, uniform temperature distribution without local overheating damaging spandex.
Auxiliary chemical tank with agitator
Automatic dissolving & metering injection of dyes, acid, alkali, leveling agents specially for elastic fiber dyeing.
Safety interlock system
Pneumatic sealed door, over-temperature, over-pressure, low-liquid level interlock protection for safe continuous operation.
Mobile beam trolley
Quick loading/unloading of single/double beams, flexible for small batch trial production and mass bulk orders.
Advantage
1. The beam dyeing machine for elastic fabric features a complete cylindrical container structure and is equipped with a high-efficiency shell-and-tube heat exchanger.
2. Its efficient shaft-driven main pump achieves internal to external circulation of the dye liquor. The equipment can adapt to flexible changes in fabric roll diameter and width.
3. The temperature regulation range covers 0 to 140 degrees Celsius, with a design operating pressure of 5.2 bar. For heating, based on 7 bar dry saturated steam conditions, the average rate of heating from 25 degrees Celsius to 130 degrees Celsius is 4.5 degrees Celsius per minute; for cooling, based on 3 bar pressure and 25 degrees Celsius cooling water conditions, the average rate of cooling from 130 degrees Celsius to 80 degrees Celsius is 3 degrees Celsius per minute.
4. The equipment supports low liquor ratio operation, ranging from 1:3 to 1:6.
Purchase Recommendations
1. Check Elasticity Content: For high spandex content (>15%), a low-tension control system is recommended.
2. Temperature Control Accuracy: Within ±1°C to prevent color variations.
3. Circulation Pump Flow Rate: Must match the fabric's permeation resistance.
4. Automation Level: Automatic feeding and online detection improve repeatability.
