Description

Technical Field

[0001] The invention relates to the technical field of yarn testing, in particular to a yarn testing device for the strength and elongation properties of a colored spun yarn. Background Art

[0002] Color spun yarn, also known as colored fiber spinning, is a yarn made by spinning two or more fibers of different colors after being fully mixed; strength and elongation testing is crucial to ensure the quality and durability of color spun yarn, and therefore, it is required to conduct strength and elongation performance testing during the production process of color spun yarn.

[0003] Current test device designs are generally limited to testing a single yarn at a time. This limitation significantly reduces the convenience and flexibility of the testing process, especially in scenarios where the performance of multiple yarns needs to be evaluated simultaneously. In addition, the traditional testing method usually fixes the two ends of the yarn and then performs a tensile test on both ends of the yarn.
