In the textile and garment manufacturing, dyeing is an inseparable process. To achieve the desired shade of clothes in the dyeing process, you need to conduct testing (Sample dyeing) instead of going for a bulk production directly. In this post, we have covered a few lab dyeing machines by Testex.
What is a lab dyeing machine?
A lab dyeing machine is widely used in textile dyeing factories to stimulate the actual dyeing production process, to improve the relevance of the dyeing formula between lab specimen dyeing results and mass production textile dyeing performance.Why use a lab dyeing machine?
Without lab dyeing machines, manufacturers will risk their business by depending on their experience only to get a specific dyeing effect, equipped with lab dyeing machines; they can repeat their dyeing test until they get a wright dyeing formula at a controlled cost.
Few common types of lab dyeing machines and their application.
1. Infrared(IR) Lab Dyeing Machine
IR Lab Dyeing Machine is suitable for all fibers and substrates dyeing. The infrared lab dyeing machine produces accurate laboratory sample dyeing with level and reproducible results and accommodates up to 24 positions with a low liquor ratio for synthetic and natural fibers. The fabric sample dyeing machine is commonly used in the laboratory.

Features of this machine
Three-dimensional turning, clockwise and anti-clockwise running makes level dyeing results. Beakers are made of quality SUS316 stainless steel, heating fast and level, specially pressure-tested beakers offer maximum safety for atmospheric and high-temperature dyeing. Infrared heating continuously (non-off-type) by durable life infrared heaters which 360-degree ring-shape, direct heating of steel cup, to let dyeing equably and saving 50% electricity. The programmable computer system controls process can save up to 99 kinds of process, LCD displays temperature, time, process No. and temperature curve, imported high-precision PT-100 temperature probe monitoring the actual temperature of dyeing liquor directly, to let heating and cooling automatically.
Specifications
- Temperature range: 30-140 °C
- Heating or cooling speed: 0.5 – 3.5 °C / min
- Temp. Control accuracy: 1 °C
- Rotation speed: 0 – 30 rpm (adjustable)
- Dyeing Beaker: 24 pots / 300ml
- Liquor Ratio: 1:5 ~ 1:100
Options: The chemical adding system, specially designed chemadd lid (dyepot cap) and chemadd pot (for chemical powder or solution additions) to add chemical without opening dyepot ensures temperature stability during the dyeing.
2. High Temp Lab Dyeing Machine

- High quality spring hold dyeing beakers exactly without inclination dyeing beakers
- High quality motor could adjust speed according to customer’s requirement.
- Easy adding auxiliary during the dyeing process
4. Lab Jig Dyeing Machine
Application
Lab Jig Dyeing Machine is used to adjust the dye formula before batch production for dyeing factories, for the dyeing testing of cotton, linen, fiber gum and artificial fiber, and can realize the bleaching and dyeing of low bath ratio, and simulate the production process of large capacity dyeing machine.
This jig dyeing machine simulates the actual production process of velocity, temperature, pre-tension, the ambient pressure parameters, etc. Jig dyeing machines are small size, less the amount of dye, change the formula flexible, short test process in a short period of time to make up an exact dye formula.
