The Dynamic Modulus Tester is a complete system that measures Sonic Velocity through materials. Physical properties derived from sonic velocity include modulus of elasticity, material anisotropy, molecular orientation in fibers and films as well as orientation of fibers in a web.

DMT SONIC VELOCITY AND MODULUS TESTER

LH-551, LH-552 DMT

  • Digital display of the transit time through material

  • User friendly software program that calculates the sonic velocity automatically

  • Fiber Scanner option for yarn and Planar Mount option for sheet material testing

FST SIMULTANEOUS SHRINKAGE% AND SHRINKAGE FORCE TESTER

LH-610 FST

FST, Force Shrinkage Tester measures the Shrinkage % and Shrinkage Force on the yarn simultaneously. The system is a closed unit, which maintains a controlled atmosphere as the test is progressing.

​

The system uses a high temperature heater to measure in Shrinkage % and Shrinkage Force. The heaters can be individually programmed up to 300˚C to run tests independent of each other. (Optional High Temp Heaters up to 450˚C).

​

The FST is equipped with 2 clamps. Different clamp designs are available to accommodate yarn types from tire cords to elastomeric yarns.

The standard load cell is 200g. Also available are load cells from 10g to 2000 g, depending on the yarn type to be tested.

​

FST Software automates all calculations for Shrinkage Force and Shrinkage % based on temperature and time parameters. In addition, built in temperature ramp feature allows the user to test the yarn against increasing temperature levels. This feature allows the operator to predict optimum temperature settings for run ability of individual yarns packages.

​

The test process is automated. A yarn sample is clamped and the test button is activated. Automatically the yarn is inserted into the closed heater chamber for testing. The software plots the shrinkage % or shrinkage force data in real time. Statistical analysis is made at the end of each test.

  • Automated testing system for simultaneous measurement of Shrinkage % and Shrinkage Force of the yarn

  • Complies with ASTM D4974, ASTM D5591, EN 13844

  • Enclosed system that maintains a draft-free environment during test

  • Dual, non-contact heaters individually programmable to run tests under constant or temperature ramp mode with 5 settings from ambient to 300˚C (Optional High Temp Heaters up to 450˚C)

  • 10g, 200g or 2000g load cell available to meet the required force measurement precision

  • Light duty or heavy duty clamp designs available to provide non-slip grip for different yarn types from elastomeric yarns to tire cords

  • Friction free pulley to measure the Shrinkage % with ± 0.1% precision

  • Five programmable temperature settings allow temperature ramp and soak interval

  • Windows based, easy-to-use software features
