3 Common Mistakes to Avoid in Fabric Tensile Testing

 

 

1. too tight or too loose:

The strain applied to the fabric during testing should be uniform and consistent; excessive stretching or relaxation can lead to inaccurate test results. When installing the fixture, make sure it holds the fabric securely, but do not use excessive force that could twist or deform the fabric and result in uneven strain.

 

2. Unstable test speed:

Test speeds that are too fast or too slow can lead to inaccurate test results. The test speed should be stable to avoid inconsistent test results due to changes in strain rate. Tests should be conducted in accordance with standard test requirements, including parameters such as test speed and strain rate.

 

3. Presence of defects:

Prior to performing a tensile test, the fabric needs to be inspected for the presence of imperfections such as wrinkles, pinholes and tears. These imperfections can affect the accuracy of the test results as they usually disrupt the physical structure of the fabric. In addition, free movement between the fabric and the fixture should be avoided during the test, as this can also lead to erroneous test results.

 

By avoiding these three common mistakes, you can ensure the accuracy and reliability of your fabric stretch tests and reduce errors in your test results. For example, you should choose the proper jaws when selecting fixtures, select the proper test speed and maintain the test equipment regularly, among other things. It is also important to check the quality of the fabric information, the production process, etc. to help ensure that accurate information and data are obtained from the test.
