Fiber Crimp Elasticity Tester
Introduction
Fiber Crimp Tester is the latest developed high precision testing apparatus. It is used to automatically measure the crimp ratio, crimp elastic recovery percentage, and number of crimps of the fiber. It adopts the image processing technology to automatically count the number of crimps within the length of 25mm on the fiber sample when the fiber bears the light load, thus it eliminates the uncertainty of manually counted results. With the force sensor the apparatus measures the values of the light load and heavy load that stretch the fiber sample, and measures the fiber lengths when the fiber is under the light load and heavy load respectively, then it calculates the crimp ratio automatically. It also measures the fiber length after the fiber have burdened the heavy load and got relaxed, and then calculates the crimp elastic recovery percentage of the fiber.
Application
It can be used to test the crimp properties of single natural and man-made fiber. Therefore, it is widely used in chemical fiber and textiles manufactories, fiber-testing inspection bureaus, and scientific research institutions, etc.
