LFY-218B Nail Hammer Wire Gripping Testing Instrument
Main application
The LFY-218B nail hammer wire drawing tester suspends a nail hammer on a chain and passes it around the guide rod to be placed on the surface of the sample wrapped around the rotating drum. When the drum rotates at a constant speed, the nail hammer randomly flips and jumps on the sample surface, causing the sample to be wire-drawn. It is used to evaluate the wire-drawing degree of outerwear knitted fabrics and other fabrics prone to wire-drawing. It is particularly suitable for synthetic fiber long fibers and their deformed yarn fabrics. The instrument has 4 working positions and can simultaneously test 4 samples. Each position has an independent switch.
