| Summary: | In various working conditions and some hazardous situations, people may be subjected to assaults by sharp objects. Therefore, protective clothing is utilized to defend the human body against dangers and damages caused by these threats. In this study several metal-reinforced fabrics were designed and prepared through a weft-backed weaving system and their protection performance was assessed. To prepare the fabric samples, different metal threads having various diameters and weave ratios were used. The designed fabric’s resistance to bending and penetration of sharp objects was measured and the outcomes showed that using metal threads in fabric structure increased the fabric resistance against bending and penetration of sharp objects in general. The impact of metal threads diameter and weave ratio was also investigated. Thicker metal threads resulted in further increasing of the fabric resistance to penetration and bending. In fabrics reinforced with metal thread that have similar diameters, the samples with lower weave ratio need considerably greater force and energy for penetration. It was also observed that the impact of weave ratio is more significant than the impact of diameter of metal threads on fabric resistance to penetration. However, in terms of fabric resistance to bending, the impact of diameter of metal threads was higher compared to number of metal threads. |
