Description

Technical Field

[0001] The present application relates to the technical field of yarn testing, and in particular to a yarn elasticity testing device. Background Art

[0002] Yarn plays an important role in many fields such as clothing, textiles and industrial applications. The quality of yarn will directly affect the performance of the final product. The elasticity of yarn is one of the key factors to measure the quality of yarn. In related technologies, the elasticity of yarn needs to be tested when processing yarn into textiles. When testing the elasticity of yarn, one end of the yarn needs to be fixed on the winding pole, and the other end of the yarn needs to be connected to a weight structure such as a weight. The elastic performance of the yarn is tested by measuring the tensile length and recovery length of the yarn.

[0003] Regarding the above-mentioned related technologies, there are the following defects: in actual applications, the yarn is not only subjected to vertical downward force, but also to twisting and forces in different directions. Testing the elasticity of the yarn only by vertical downward force will reduce the testing accuracy of the yarn. At the same time, in the related technology, when testing different types of yarns, they need to be tested one by one, which will lead to a decrease in the testing efficiency of the yarn.
