Catering to the distinct process requirements of different fabrics, the Hthp Beam Dyeing Machine supports both unidirectional and bidirectional liquid flow operations. Its reliable performance and precise control make it an ideal choice for fulfilling the high-end dyeing needs of a broad spectrum of high-quality fabrics.
Product Features
Included are a complete cylinder container structure, a high-efficiency shell-and-tube heat exchanger, and a high-efficiency warp main pump that circulates liquid from inside to outside. It adapts to variable cloth winding diameters and widths, with temperature control spanning 0-140℃ and a design pressure of 5.2bar. The heating rate from 25℃ to 130℃ averages 4.5℃ per minute (using 7bar dry saturated steam), while cooling from 130℃ to 80℃ averages 3℃ per minute (with 3bar, 25℃ cooling water). It operates at a low liquor ratio of approximately 1:3 to 1:6.
Component Functions
Perforated beam
Secures the fabric roll and allows dye liquor to circulate.
Pressure vessel
A stainless steel chamber (compliant with ASME standards) for high-temperature/high-pressure dyeing.
High-pressure pump
Forces the dye liquor to penetrate the fabric evenly.
Heat exchanger
Maintains precise temperature control.
Expansion tank
Compensates for thermal expansion of the dye liquor.
PLC automation system
Controls temperature, pressure, flow, and cycle time.
Safety system
Includes a pressure relief valve, emergency cooling, and an alarm.
Dye filtration system
Removes impurities to prevent fabric defects.
How it works
Fabric is tightly wound onto a perforated beam, which is then loaded into the machine's sealed, pressure-resistant cylinder. Dye liquor is pumped through the beam, flowing from the interior to the exterior of the fabric roll. Under high temperature and pressure, dye molecules are efficiently absorbed by the fibers, with the heat exchanger maintaining stable temperature levels throughout the cycle. After the dyeing process, the system cools rapidly, and excess dye is rinsed away, resulting in uniformly dyed fabric with excellent color fastness.
Maintenance and Precautions
1.Regularly clean the nozzle (to prevent clogging), check the high-pressure pump for leaks, and calibrate the temperature control system.
2.Pre-treat the fabric (e.g., scouring and bleaching) to prevent impurities from affecting the dyeing results.
3.Strictly follow safety regulations during operation (e.g., high-pressure pump protection and electrical equipment grounding).
