Description

Technical Field

[0001] The utility model relates to the technical field of fiber tensile performance testing, in particular to a fiber tensile performance testing clamp. Background Art

[0002] Since naturally grown animal hair fibers are affected by multiple factors during their growth process, the coefficient of variation of their single fiber strength is over 30%. Therefore, the standard currently promoted by the International Organization for Standardization is: the most commonly used breaking strength test method for natural fibers (especially wool and wool bunches) is the bundle fiber method.

[0003] During testing, accurate data is obtained only when the clamped test material does not slip or become damaged in the gripper. Currently, electronic single-fiber strength testers are commonly used to test the breaking strength and elongation of natural plush fibers. Because the clamping surfaces at the jaws of these machines are relatively fixed, the grippers have high requirements for the regularity of the test material. If the clamping force is too weak, the relatively fixed clamping surfaces can cause some of the test material to slip and break away. If the clamping force is too strong, some of the test material can be easily broken, making existing grippers unsuitable for testing bundled fibers. Utility Model Content
