A discussion of common problems and solutions for fabric shrinkage testing

Fabric shrinkage is the degree to which a fabric shrinks in overall size during washing or dry cleaning as the fibres move towards each other and shorten. It is important for production and manufacturers to understand fabric shrinkage as it can affect the size, quality and appearance of the product. The following are common problems in fabric shrinkage testing and their solutions:
 

Problem 1: Inaccurate test results.

 

Solution: Inaccurate test results can be caused by errors in the test instrument or incorrect operation during the test. To obtain accurate test results, you should use a calibrated test instrument and follow the instructions for the test method to ensure accuracy.

 

 

Solution: Different types of fabric correspond to different test methods. If an unsuitable test method is used, the test results may be inaccurate. Therefore, before testing fabric shrinkage, you should know the type of fabric being tested and choose the appropriate test method.

 

 

Solution: The size of the test sample should be large enough to ensure the accuracy of the test results. Typically, the test sample size should be somewhat larger than the fabric being produced. If the test sample is not large enough, other more appropriate testing methods can be chosen, such as using a large test instrument or averaging the test using multiple test samples.

 

 

Solution: The temperature, humidity and air pressure of the test environment can affect the test results. Therefore, before conducting the test, you should ensure that the test environment meets the test requirements and make the necessary adjustments to the test environment to ensure the accuracy of the test results.
 

In summary, common problems in fabric shrinkage testing include inaccurate test results, inappropriate test methods, test samples that are not large enough and unsuitable test environments. In order to obtain accurate test results, a suitable test method should be selected, using a calibrated

fabric shrinkage tester and ensure that the sample size is large enough and that the test environment meets the test requirements.
