Description

Technical Field

[0001] The utility model relates to the technical field of textile testing, in particular to a textile resilience testing device. Background Art

[0002] With the continuous development of the textile industry and the continuous improvement of people's living standards, consumers are paying more and more attention to the functionality of clothing fabrics.

[0003] Due to the explosive development of elastic fabrics at this stage, a large number of fabric manufacturers have also transformed to process and produce elastic fabrics. However, due to the uneven equipment and technical capabilities of manufacturers, the quality of the fabrics produced also varies greatly. As a result, the final consumers also buy clothing of uneven quality, which has a great impact on consumer interests. How to accurately and quickly provide elastic fabric stretch testing for major manufacturers is the top priority for the development of third-party testing agencies.

[0004] There are two main aspects of elastic fabric assessment: the first is the "stretching" of the fabric, and the second is the "shrinking" of the fabric. In simple terms, it is how much the fabric can stretch after applying external force, and whether the fabric can return to its original state after stretching. The assessment of the two aspects can accurately evaluate the quality of the fabric. There are also many testing methods for elastic fabrics at home and abroad, such as EN 14704-1 <Fabric Elasticity Test-Strip Sample Strength Test> in Europe, FZ / T 70006-2017 <Knitted Fabric Stretch Elastic Recovery Rate Test Method> in China, and ASTM D4964 <Elastic Fabric Recovery Rate Test Method> in the United States. At present, there are great differences in the selection and operation methods of fabric elastic recovery tests among major testing institutions, and some manufacturers also have their own testing methods, which leads to great differences in test results. In the resilience test, it is necessary to apply external force to the tested textile, and then obtain the elongation and recovery of the textile under the applied external force. Therefore, the key to the test is that the applied external force acts evenly on a certain width of textile. Utility Model Content
