Automation Solutions Enhancing Efficiency in the Fiber Dyeing Industry

The textile dyeing industry is one of the sectors with complex production chains and high technological requirements. However, up to 50% of machinery and equipment in the textile dyeing industry in Vietnam are technologically outdated by about 15 – 20 years compared to Thailand and China, and 25 – 50 years compared to the world. Therefore, optimizing machinery and equipment, and improving technology should be the top priority for textile dyeing enterprises today because this investment will help reduce input material losses, increase productivity, and enhance the value of goods in the export market.

Some successful solutions applied in many fiber dyeing factories include:

  1. Solution: Installing variable frequency drives (VFDs) to control motor speeds to improve technology, optimize performance, and save energy:

With the ability to change the frequency of current, thus altering motor speeds, VFDs are widely used in electrical and automation systems. The textile dyeing industry is no exception. By installing VFDs to control motor speeds, dyeing factories can increase productivity and save energy.

Machines that can use VFD installation solutions in the dyeing industry include:

  1. Solution: Energy-saving and technological improvement for industrial boiler systems

Boilers are essential equipment in textile dyeing factories, using fuels such as coal, wood, rice husks, and waste paper to boil water and generate steam for various processes in the factory.

Old-style boiler systems often use pressure relay methods to directly control the opening/closing of exhaust and blower fans for air supply and smoke discharge. Motor control for blower and exhaust fan start-up is achieved through star-delta starting circuits.

Challenges faced by factories using the old operating method:

  • Unstable steam flow and pressure.
  • Unsmooth start-up, causing mechanical shock, frequent mechanical and engine checks and maintenance.
  • Motors always run at full capacity, wasting electricity.
  • The system requires many electrical devices such as timers, relays…
  • The system generates a lot of exhaust gas and sudden increases in the concentration of harmful substances, affecting health and the environment.

The solution is to use the INVT GD200A new-generation multi-purpose variable frequency drive to control the blower motor, exhaust fan motor, and feed conveyor motor of the boiler system to stabilize steam flow and pressure, saving electricity and increasing the motor’s service life. At the same time, upgrading the system to achieve higher production efficiency.

  1. Solution: Stable control and energy saving for multi-pump systems

Water pumps and multi-pump systems are widely used in fiber dyeing and water treatment areas.

The old-style pump control method uses 3-phase motors started in star-delta or direct connection to the grid. When operating, the pumps always run at full load until the tank/reservoir is full or the pumps have enough water, then the pumps are shut off.

Challenges faced by factories using the old operating method:

  • Pumps have high start/stop frequency, reducing pump life.
  • Pumps always operate at full power even when demand is low, wasting energy.
  • Voltage drop in the electrical system due to simultaneous starting of many pumps.
  • Cost and space required for building water towers (for water distribution stations).
  • Unstable water pressure and flow rate affecting other systems and causing pipe breakage, valve damage…
  • Some pumps work too much or too little, causing damage and corrosion to components.
  • Increased operating, maintenance, and repair costs.

The solution is to use the INVT GD300-16 dedicated HVAC variable frequency drive to control the pressure-regulating and alternating operation of the pump system, solving all the above problems completely. INVT inverters GD300-16 integrates many smart functions, including pressure regulation, alternating and soft start-up control when adding or reducing pumps (expandable up to 11 pumps), operating time balancing (anti-rust) for pumps, monitoring and controlling water supply levels to prevent pump idling, real-time control (peak and off-peak hours) to optimize electricity savings.
