Infrared Lab Dyeing Machine: GESTER GT-D22A vs FYI RHS-24

Introduction

An infrared lab sample is used in the fabric dyeing lab before bulk production.  An infrared lab dyeing machine is crucial equipment for dyeing knit fabrics. It is used to develop laboratory dyeing recipes before bulk production. This article compares two infrared lab dyeing machines: the GESTER GT-D22A and the Fanyuan RHS-24.  Both machines are developed for laboratory use in textile dyeing lab. The basic purposes of these machines are the same. But the question is: are they the same? Which machine offers better performance for laboratory dyeing? Thought they have similar basic functions, but there are some differences in their temperature range, rotation speed, and power supply. Let’s compare their specification and practical dyeing performance.

GESTER GT-D22A

The GT-D22 is an infrared laboratory sample dyeing machine developed by GESTER. It is designed for high-temperature sample dyeing and washing fastness tests, for example, knitted fabric, woven fabric, yarn, cotton, zippers, and scattered fiber. The machine uses infrared heating system to heat the dyeing cups. It also has an air-cooling system to reduce the temperature after the dyeing process. The machine supports a programmable dyeing process. According to GESTER’s published specification, The GT-D22 series is available in 12-cup and 24-cup.

Main features of GESTER GT-D22

• Heating System: Infrared heating system
• No. of dyeing pots: 12-24 pcs steel pots
• Power source: AC 220 V, single phase
• Maxi. Dyeing temperature: 140⁰ C
• Liquor ratio: 1:5-1:100           
• Heating power: 4(6)×1.2 Kw, blows motor power 25 W
• Heating medium: Oil bath heater transfer
• Driving motor power: 370 W
• Rotation: 0-60 RPM
• Air cooling motor power: 200 w

Fanyuan RHS-24

The RHS-24 is an infrared lab dyeing machine developed by Fanyuan Instrument Co. Ltd. It is also designed for laboratory-scale dyeing of textile materials. The machine uses infrared heating with oil conduction. This heating system helps to transfer heat to the dyeing cups.

Main features of Fanyuan RHS-24

• Heating System: Infrared heating system with oil conduction
• No. of dyeing pots: 24 steel pots
• Power source: AC 3800 V, 3 phase
• Maxi. Dyeing temperature: 135⁰ C
• Liquor ratio: 1:5-1:100           
• Heating power: 4(6)×1.2 Kw, blows motor power 25 W
• Driving motor power: 370 W
• Rotation: 0-50 RPM
• Air cooling motor power: 200 w

Main Differences Between Two Infrared Lab Dyeing Machines

Although both machines have almost the same features, they have some small differences

• RPM: RPM, or the rotation speed, is an important feature in dyeing machines. Because it influences the dye take-up from the liquor. RHS-24 offers a rotation speed of 0-50 RPM. But GT-D22 gives a maximum rotation speed of 60 RPM. It depends on the version.
• Power supply: The power supply is another important parameter. The Fanyuan RHS-24 is listed with a 380 V, three-phase power supply. The GESTER GT-D22A is listed with a 220 V single-phase power supply.
• Temperature range: The published maximum temperature of the Fanyuan RHS-24  is 135°C, while the GESTER GT-D22  has a maximum temperature of 140°C.

Practical Dyeing Test

Although technical specifications are important, actual dyeing performance is also important. To compare the two machines, I carried out a dyeing test using knitted fabric. I used same dyeing recipe, time and temperature. I didn’t observe any significant differences between the two dyed samples.

Conclusion

GESTER GT-D22 and Fanyuan RHS-24 are two infrared lab dyeing machines designed for textile dyeing. Their technical specifications are almost the same. There is no universal answer to which machine is better. If you have any point, leave them in the comment box below.
