When sharp objects go through the fibers, cause textil`damage. in additionaly they may hurt the body. Nowadays protecting against sharp objects specially knives is crucial. The purpose of this project is increasing of a nonwoven` resistance against sharp sharp objects. So for reaching this purpose, ceramics should be used. This ceramics were silicon carbide, kaolin and nano silica.The ubstrate was polypropylene nonwoven that was treated with the ceramics. The treatment was done with two methods: blade coating and deep coating. In coating methods, binder, thickener agent and ceramics. They came on our substrate like a resistant layer. In deep coating methods, poly etylene glycol in ethanol is used but in this project, we used crosslinking agent by replacing ethanol to water. With catalysis and proper conditions, the layers were treated. Two tests was done on treatment nonwoven`s layers: Static and dynamic tests. Static test was done with needle but in dynamic test, the test was done with throwing the knife. In both test, impact energy was important. In the other hand, ability of nonwoven layers for dissipating this energy was important. Moreover, the effect of material and process variables such as weight and punching densities of layers, kind and amount of ceramics, fiber denier, make layer more resistant and crosslinking agent in deep coating method was studied. The result of this study showed that by increasing the weight and punching densities of layers, the amount of ceramics, make layer more resistant , resistance of nonwoven against sharp object increase. crosslinking agent that was used in deep coating methods, had good results in resistance of layers. The effect of fiber denier and kind of ceramics in blade coating and deep coating methods were different. In deep coating methods, increasing of fiber denier made layer more resistant against sharp objects but in blade coating methods the result was opposite. Results showed that in both methods, silicon carbide made layers the most resistant against sharp objects. In deep coating methods, kaolin was better than nano silica and in blade coating methods, the result was opposite
