The textile industry uses the infrared sample dyeing machine. It is for dyeing fabric samples. It uses the principle of infrared radiation. This provides a controlled and efficient way to dye small batches of fabric. Here’s an overview of its working principle:
Components and Structure:
Infrared Heating System:
Utilizes infrared lamps to generate heat.
Provides consistent and uniform heating.
Sample Dyeing Vessels:
Small containers or beakers that hold the fabric samples and dye solution.
They are usually made of stainless steel. This is a material resistant to chemicals and high temperatures.
Temperature Control System:
Monitors and controls the temperature precisely.
It ensures that dyeing occurs at the best temperature. This temperature is best for the specific dye and fabric.
Stirring Mechanism:
Ensures an even distribution of dye and heat within the vessel.
Prevents fabric from settling and ensures uniform dyeing.
Timing Mechanism:
Controls the duration of the dyeing process.
You can adjust it based on the type of dye and fabric.
Working Principle:
Preparation:
We prepare fabric samples and place them in the dyeing vessels along with the dye solution.
To prevent evaporation and contamination, we seal vessels.
Heating:
The infrared heating system activates.
Infrared lamps emit radiation. The vessels absorb it, causing them to heat up.
The heat is transferred to the dye solution and fabric.
Temperature Control:
The temperature control system tracks vessel temperatures in real time.
We make adjustments to keep the desired temperature. This ensures the dyeing process is optimal.
Stirring:
The mechanism shakes the dye solution in regular intervals.
The dye distributes uniformly throughout. It stops uneven dyeing or hotspots.
Dyeing Process:
The fabric absorbs the dye from the solution as it is being dyed.
The process continues for a predetermined duration, controlled by the timing mechanism.
Cooling and rinsing.
After completing the dyeing process, turn off the heating system.
Allow the samples to cool.
The fabric samples are then removed from the vessels, rinsed, and dried.
Advantages:
Uniform Heating: Infrared radiation provides consistent and uniform heating, ensuring even dyeing.We control temperature and time precisely to produce consistent outcomes.
Efficiency: Rapid heating and cooling cycles make the process efficient and time-saving.
Versatility: Suitable for a wide range of dyes and fabrics.

Q1: Why should I choose an Infrared Sample Dyeing Machine instead of a Glycerin Sample Dyeing Machine?
A1:
The Consistency and Reproducibility of Dyeing
Infrared Sample Dyeing Machine can provide higher sample consistency and experimental reproducibility due to its uniform heating and precise temperature control. Glycerin dyeing sample machines are not uniformly heated, which can lead to inconsistent dyeing results from batch to batch.
Save time and efficiency
Infrared dyeing prototypes use infrared heating technology to reach the desired dyeing temperature more quickly, shortening the time required for heating up and cooling down. Glycerin dyeing machines, on the other hand, the heating and cooling speeds are slow, making the experiment less efficient.
Besides, infrared heating is more energy efficient than glycerin heating. Glycerin can evaporate or leak, potentially contaminating equipment and the experimental environment and increasing the frequency of cleaning and maintenance.
Infrared Lab Dyeing Machine is safer. Glycerin is dangerous at high temperatures and can cause safety hazards such as oil leakage or overheating. The IR Dye Machine is safer to operate because it uses non-contact heating and there is no risk of spillage or leakage of the medium.
Q2: Why should I choose ChiuVention InfraDye Sample Dyeing Machine?
A2: Our infrared Sample Dyeing Machine in addition to the common advantages: such as temperature calibration, uniform dyeing effect, but also can be connected to smartphone and enterprise ERP or LIMS system through the IoT technology. So you can remotely master the sample dyeing test situation, and you can enter the fabric sample dyeing effect report into the system, then it can directly be sent to the relevant staff or departments. ChiuVention InfraDye Dyeing Lab Equipment is a true digital intelligent instrument, effectively improve work efficiency!
Q3: How to ensure the dyeing effect of fabric sample?
A3:
Precise control of temperature and time
The core advantage of infrared dyeing machine lies in the accuracy of temperature control, so the temperature and dyeing time should be set reasonably:
Temperature rise rate: Make sure the temperature rise rate matches the dye type and fabric, different dyes may have different sensitivity to temperature. Different dyes may have different temperature sensitivities. Setting the right temperature profile will help the dye adhere more evenly to the fabric.
Constant temperature time: ensure that the constant temperature during the dyeing process is sufficient to ensure that the dyestuff can fully penetrate and fix into the fabric fibers.
Cooling rate: control the cooling rate of sample dyeing, too fast cooling may lead to uneven fixation of dyes, affecting the final color effect.
Evenly placed samples
Sample placement will directly affect the uniformity of dyeing. To avoid uneven dyeing or color differences:
Sample Distribution: Ensure that samples are evenly distributed within the dye bath, avoiding stacking or overlapping to ensure that each section receives uniform infrared heating and dye action.
Stirring or turning: If supported by the lab dyeing equipment, use the automatic stirring function or turn the samples periodically during the manual dyeing process to ensure that the dye is evenly distributed in the dye bath.
Optimize dye formulation
Different dyestuffs interact with different fibers in their own way, so the dye formulation should be optimized according to the dyeing needs:
Dye concentration: Reasonable configuration of dye concentration to avoid too much or too little dye, which will affect the color saturation and uniformity.
Auxiliary addition: According to the type of dye and fiber characteristics, add appropriate dyeing auxiliaries (such as wetting agents, dispersants, pH adjusters, etc.) to help the dye adsorb more uniformly onto the fibers.
Use of appropriate dyeing process
Different fibers and dyestuffs require different dyeing processes, so choosing the right process parameters is crucial:
Dye type selection: Ensure that the dye matched to the fiber is used (e.g. reactive dyes, acid dyes, disperse dyes, etc.), as different fibers have different affinities for dyes.
Dyeing bath ratio: Ensure that the ratio of dyeing liquid to sample is reasonable. Insufficient amount of dyeing liquid may lead to uneven distribution of dyes and affect the dyeing effect.
Regular cleaning and maintenance of equipment
The IR dyeing sample machine needs regular cleaning and maintenance to ensure its heating efficiency and uniformity:
Clean the dye residue: After dyeing, clean the inside of the lab dyeing equipment in time to prevent the dye residue from affecting the next dyeing.
Check the infrared lamps: Check the performance of the infrared lamps regularly to make sure that the heating is even and not damaged to avoid uneven dyeing caused by equipment failure.
Pre-treatment and post-treatment
In order to further improve the sample dyeing effect, you can also pay attention to the pre-treatment and post-treatment of the samples:
Pre-treatment: Ensure that the fabric has been adequately pre-treated before dyeing, such as desizing, bleaching and other steps to improve the adsorption capacity of the fiber to the dye. Post-treatment: The treatment such as fixing and washing after dyeing can improve the durability and fastness of dyeing and prevent fading or dye loss.
Experimental records and optimization
Record the temperature, time, dye formula and other parameters of each dyeing, and continuously adjust and optimize according to the experimental results to find the best process combination, so as to ensure the consistency and stability of the dyeing effect.
