AI Technical Summary
Existing technologies for testing yarn elasticity are limited and cannot accurately measure the elastic strength of yarn, especially since the differences between longitudinal and transverse tensile directions are not fully considered.
A yarn elastic strength testing device was designed, which adopts longitudinal and transverse tensioning components. The yarn is driven to stretch longitudinally by a lead screw and a geared motor, and the longitudinal elastic strength is measured by a pressure sensor. The yarn is stretched transversely by the elastic force of a spring, and the transverse elastic strength is measured by a second pressure sensor.
It enables diversified testing of yarn in both the longitudinal and transverse directions, resulting in more accurate results that comprehensively reflect the elastic properties of the yarn.
