Common Dyeing Equipment Processes and New Dyeing Techniques – Part 4

Common Dyeing Equipment Processes and New Dyeing Techniques – Part 4

Section 1 Common Dyeing Equipment – part 4

Jig dyeing machine


1. Dyeing tank 2. Guiding roller 3. Rolling roller 4. Fabric

5-Steam pipe 6-Speed control gearbox

Features: When a regular dyeing machine is running, only one fabric roller is active, and the fabric is subjected to a large tension. Moreover, with the different size of the fabric roll, the linear speed and tension of the fabric vary. The improved constant speed dyeing machine, through the action of speed control gears, makes both fabric rollers active, and the linear speed during fabric winding is basically consistent, reducing the tension on the fabric.

Star frame dyeing machine


1. Fabric 2. Copper hook 3. Star shaped frame 4. Dyeing tank 5. Pump

Features: The star frame dyeing machine is suitable for dyeing fabrics that are not resistant to rolling and pressure (such as velvet) and fabrics that are prone to abrasion (such as silk fabrics).

Continuous pad dyeing machine

A continuous rolling and dyeing machine generally consists of several parts, including a soaking and rolling device, a drying device, a steam box, a drying box, and a water washing device.


1. Feeding frame 2. Three rollers padder 3. Infrared pre drying 4. 10. Drying cylinder drying 5. Reduction immersion rolling tank

6-Reduction steam steamer box 7,9-Flat washing tank 8-Soap steamer box 11-Cloth dropping rack

Features: Continuous dyeing equipment is suitable for dyeing and processing large quantities of fabrics, with high labor productivity. However, it consumes a large amount of dyeing and chemical materials, energy, equipment investment, and occupies a large area.

Drying method

1. Infrared drying: It uses infrared thermal radiation to penetrate the interior of the fabric, causing water to evaporate. This method uniformly heats the fabric, is not prone to dye migration, has high drying efficiency, and occupies a small area of equipment.

2. Hot air drying: It is the process of drying fabrics by spraying hot air from the nozzle. The evaporated moisture on the fabric escapes into the air, increasing the humidity of the air inside the machine. So, this type of dryer has low drying efficiency and a large footprint. Both infrared and hot air drying methods belong to non-contact drying, and the fabric is subjected to less tension.

3. Drying with a drying cylinder: It is the process of heating the surface of a metal cylinder through steam to evaporate moisture from the fabric. It has high drying efficiency, but if the temperature is not well controlled, it is easy to cause dye migration. Therefore, it is advisable to first lower and then higher the temperature during operation.
