How to judge whether the shrinkage rate of the fabric meets the standard?
The standards for fabric shrinkage are usually formulated by relevant international or industry organizations, such as ISO, ASTM, AATCC, etc. Different fabric types and uses may have different shrinkage standards. Therefore, judging whether the shrinkage rate of the fabric meets the standard needs to first determine the type and use of the tested fabric, and then consult the relevant standards.
After determining the applicable standard, the following steps can be used to judge whether the shrinkage rate of the fabric meets the standard:
1. First, compare the shrinkage of the tested fabric with the applicable standard.
2. If the shrinkage rate obtained from the test is lower than the maximum shrinkage rate specified in the standard, the fabric can be considered to meet the standard.
3. If the shrinkage rate obtained by the test is higher than the maximum shrinkage rate specified in the standard, the fabric is considered not to meet the standard.
It should be noted that different standards may have different testing methods and requirements, so when judging whether the fabric meets the standards, it is necessary to carefully read the specific requirements of the standards, and conduct tests and judgments according to the standards.
