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.
