Automatic Long Filament Curl Shrinkage Tester
Category：textile Functional tester
Introduction
The automatic long filament curl shrinkage tester is designed for measuring boiling water shrinkage rate, dry heat shrinkage rate, curl shrinkage rate, curl modulus, and curl stability of synthetic fibers (polyester, nylon, polypropylene). Features include automatic load adjustment, auto-loading, timing, length measurement, and zero calibration during testing. Results are calculated and printed automatically.
Applicable Standards

GB/T 6505 – Test method for thermal shrinkage rate of chemical fiber filaments (post-treatment)
System Composition
Main unit
Two yarn frames
Lenvovo brand computer
Printer
Special constant-temperature oven (for dry heat/curl shrinkage tests)
Special constant-temperature water tank (for boiling water shrinkage tests)
