LFY-204 Fabric Elasticity Testing Instrument

【Scope of Application】 
This machine is mainly used for measuring the elastic elongation and residual elongation of elastic woven fabrics under the specified elongation conditions. 
【Test Principle】 
According to the test principle of ASTM D 3107-2007, under the specified load, the length increase of the sample after a certain number of stretching cycles is measured. After the load is released, the length of the sample is re-measured after a certain time interval. The elongation of the fabric is based on the length before stretching, and the increase in length under the load. The instantaneous residual elongation is based on the length before stretching, and the difference in length after the brief (30 seconds) recovery after the load is released. 
【Instrument Characteristics】 
The all-stainless-steel frame design is elegant and stylish. 
2. It is capable of conducting tests at any single workstation at any time, or simultaneously for two workstations. 
3. The instrument is equipped with a standard stainless steel ruler (with 1mm markings) 
4. 2 sets of 4lb standard load weights 
【Technical Specifications】
