Experimental investigation on stab-resistant properties of co-woven-knitted fabric

Using glass fiber and polyester fiber as raw materials, stab-resistant properties of co-woven-knitted fabric are explored in this paper. A quasi-static stab-resistant performance test was conducted to study the stab-resistant characteristic of co-woven-knitted fabric pierced by a knife according to the puncture, displacement of puncture and puncture strength, and other parameters, recorded during the experiment. Three angles, 0°, 45°, and 90°, were chosen to explore the relationship between angles and puncture strength. Results indicate that the continuous shear resistance of multiple fibers in woven fabric and the weft-knitted yarns gathered after the locking effect in knitted fabrics work together during the experiment. It shows an increase of anti-shear effect of the fabric and an improvement of the anti-puncture ability. The puncture angles influence the puncture strength, and 45° shows the largest puncture force.
