Experimental apparatus is extracted to flexible fabric yarn line

Experimental apparatus is extracted to flexible fabric yarn line belongs to flexible fabric yarn line and extracts the technical field of evaluation. The device is including rigidity frame, centre gripping fixture, slide rail, slider, pretightning force applying mechanism and plug. The fabric test piece is by centre gripping fixture centre gripping, presss from both sides tightly through clamp bolt, and the centre gripping fixture remove the end and link to each other through slide rail and rigidity frame. It is vice that the fabric clamping face of centre gripping fixture is fixed with the friction, guarantees that it can not take place the slippage to extract the in -process fabric at the yarn. The centre gripping fixture remove the end and the slider is installed together on the rigidity frame, remove along the slide rail direction to apply the pretightning force to the fabric, and guarantee that fabric test piece atress is even. Flexible fabric test piece can be added pretightningforce in the section by t
