  • Properties of Leno Fabric as Stab Resistant Clothing Material

抄録

<p>Protective clothing is an indispensable equipment for guards, police officers and so on. Although in Japan, the Firearms and Swords Control Law is strictly enforced, nails, ice picks, and such daily goods with sharp tips are not subjected to the law. Ordinally stab proof vests were comprised by metals, thus they are very heavy and poor at air ventilation. Recently, textile materials made of high performance fibers attract attentions. Nevertheless, during stabbing, the interlace points of warps and wefts slide off from their positions without yarn breakage. Hence, we cannot obtain products with high performance as we expected from raw material’s properties. In this paper, we discussed a leno fabric. Traditionally, they have been considered to be a thin, light, and sheer fabric for summer clothing. We have noticed that leno fabrics have a level of strength even though their lightness and high air ventilation. In leno fabrics, the intersection points of warps and wefts are locked by crossing of the paired warps. Such locking structure makes leno fabrics durable. In the experiment, air ventilation and stab resistance was tested and compared with an ordinally fabric. The results show that the air ventilation performance of the leno fabric is much higher than the ordinally fabric of similar weight. Additionally, stab properties of the leno fabric are not inferior in comparison with the ordinally fabric. Thus, we conclude that leno structure is a possible technique to design stab proof fabrics for protective clothing.</p>
