LFY-234A Fabric Anti-Wrinkle and Anti-Stain (Washable and Wearable) Testing Instrument

Main application
This instrument is used to measure the anti-wrinkle and anti-stretch properties of fabrics after they are soaked in water (i.e., the washable wearability). It is used to evaluate the anti-wrinkle finishing effect of fabrics.
Test principle
Take a sample of a certain size, immerse it in a specific solution, then fix it on the clamp of this instrument, twist it, keep it stretched, dry it in the required light, and compare it with the standard sample for rating by human eyes. This method is practical and has good reproducibility (using five-level sample ratings, the best anti-stretch property is level five, and the worst is level one).
