Fiber Shrinkage Tester
INTRODUCTION
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 3000C to run tests independent of each other.
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.
An extremely flexible WindowsT based FST Software package automates all calculations for Shrinkage Force and Shrinkage % based on temperature and time parameters. This feature allows the operator to predict optimum temperature settings for runability 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. At the end of the test, the results are automatically saved and can be viewed at any time.
