LFY-218A Drum-type Fabric Wire-Weaving Testing Instrument

Instrument Usage
This instrument is used to measure the wire formation and fraying of fabrics, especially synthetic fiber fabrics and knitted fabrics.
Instrument Features
1. The wire formation test is conducted using the needle cylinder method. A strip sample is fixed on the rotating cylinder, with one end being free. When the cylinder rotates periodically and rubs against a needle cylinder with certain resistance, the sample undergoes wire formation.
2. The frictional resistance torque of the needle cylinder is provided by an elastic resistance device, which can be adjusted. The contact condition between the sample and the needle tip can be changed by adjusting the adjusting rod above the needle cylinder.
3. The fabric clamping cylinder uses a worm gear and worm transmission. It generally does not require oiling and is convenient for maintenance.
4. The number of needle cylinder rotations is digitally displayed. The number of rotations can be preset, and the rotation stops when the preset number is reached. Technical indicators
