XL-2 Yarn Tensile Tester

   Introduction

      The XL-2 Yarn Tensile Tester is a function-extended type of the XL-1A apparatus. Besides the normal tensile test, it can implement a series of yarn tensile tests, such as the elasticity at specified elongation, circulating elasticity at specified elongation, elasticity at specified load, circulating elasticity at specified load, relaxation, and creep tests etc., It can be applied to the tensile test of elastic yarns.
