Wool Shrinkage Tester
Category：Other
Introduction
Product Introduction
The Wool Shrinkage Tester is a precision instrument designed for determining the length change of wool fabrics, towels, and other textile samples under standard tension.
The instrument operates based on a constant load tensile method and adopts a Constant Rate of Elongation (CRE) detection mechanism to ensure the sample is stretched uniformly during testing.
Equipped with microcomputer control, a large LCD screen, automatic data processing, and an integrated printing function, the tester provides fast, accurate, and user-friendly operation, making it ideal for textile laboratories and quality inspection departments.

FAQ
1. What type of fabrics can be tested with this instrument?
The tester is mainly designed for wool fabrics, wool-blend textiles, and towels, but it can also be used for other lightweight fabrics requiring elongation and shrinkage evaluation under standard tension.
2. What is the purpose of using the CRE elongation mechanism?
The Constant Rate of Elongation mechanism ensures a uniform stretching speed, which improves test repeatability and reduces mechanical fluctuations during measurement.
3. Does the machine require external software?
No. The instrument includes a microcomputer control system and automatic data processing. All operations and results can be performed and viewed directly on the built-in system.
4. Can test data be printed directly?
Yes. The instrument is equipped with an integrated micro printer that allows immediate printing of test reports for documentation and quality control.
5. How is the force calibration performed?
The tester supports calibration with optional standard weights (50–200 cN). This ensures long-term measurement accuracy and compliance with testing standards.
