Controlling fabric shrinkage is vital for textile factories. It ensures that the fabric meets the buyer’s needs and is of high quality. So, this Fabric Shrinkage Test Machine is a wise choice. For more information, such as the test method and formula, do not hesitate to contact us! We also provide colour fastness to washing machines.
The SmartShrink Fabric Shrinkage Rate Tester is able to quickly measure the dimensional changes of fabrics under washing, soaking or high temperature conditions accurately, helping factories to quickly get the shrinkage performance of fabrics in use. With the fabric shrinkage data, factories can adjust their production processes to ensure fabric stability, resulting in improved product quality, fewer customer complaints and more orders.
Taking as little as 5 seconds to measure a piece of fabric, saves laboratories a great deal of time in fabric shrinkage testing. The shrinkage test results are much more reliable.
The fabric shrinkage rate test reports can be generated automatically, which is convenient for fabric factories or laboratories to select qualified fabrics.
The SmartShrink Fabric Shrinkage Rate Tester can be applied to various types of fabrics, such as cotton, polyester, blended, and knitted fabrics.
1. Preparation
Environmental requirements: Ensure that the temperature and humidity of the test environment meet the standard conditions for textile testing (typically 20°C to 25°C and 65% ± 5% humidity).
Calibration samples: Use standard calibration samples of known dimensions, usually of accurately calibrated textile material, for comparison of test results.
Measuring tools check: Ensure that the tools used for measurement (e.g., straightedge, tape measure, etc.) have been calibrated regularly to provide accurate dimensional data.
2. Calibration steps
Pre-calibration check: Ensure that the fabric shrinkage rate tester’s sensors, optics, electronics, and display system are in good working order and free from external damage or malfunction.
Pre-measurement marking: Place the calibration sample (usually a standard-sized textile) flat on the measurement area and mark multiple fixed points (e.g., corners and center points) on the sample as required for measuring dimensions in different directions.
Initial measurements: The initial length and width of the sample are measured by using the fabric shrinkage tester and the dimensional data are recorded.
Perform Standard Tests: Shrinkage tests are performed according to standard operating procedures (usually including washing, drying, or other environmental simulations) and experimental data are recorded.
Final Measurement: Measure the final length and width of the sample using the shrinkage tester again to ensure that the tester’s measurements match the actual dimensional changes of the sample.
3. Data Comparison
Compare the initial and final dimensional data measured by the tester with the known shrinkage data of the standard sample. If the test results deviate within the allowable range, the calibration is complete; if outside the allowable range, further adjustments are required.
4. Software and firmware updates
Software calibration: Some Smart Shrinkage Testers are equipped with calibration software or firmware updates (You can contact us for ChiuVention Shrinkage Rate Tester Cloud Calibration.) During the calibration process, use the instrument’s dedicated software to automatically adjust the device’s internal settings according to the values of standard samples to ensure its accuracy.
Firmware update: Check regularly with the manufacturer for device firmware updates, upgrades may correct potential measurement bias issues.
5. Verifying Calibration
After completing the calibration, test the tester using a series of samples of different sizes and materials to ensure that the shrinkage measurements of different samples are within the standard range and to validate the calibration of the tester.
6. Periodic Maintenance and Recalibration
It is recommended to carry out regular maintenance and recalibration according to the frequency of use, especially after a long period of use, or after the equipment has been moved or repaired, in order to ensure the measurement accuracy and stability of the instrument.
7. Record keeping
Retain the data, deviation correction values, and calibration dates from each calibration process for subsequent inspection or audit. This is part of the quality control of the assurance equipment.
