Process and Ballistic-resistant Buffer Effect of Cushion Composite Layer Made of Three-dimensional Crimped Hollow Fiber

摘要

This study utilized a 3D crimped hollow fiber web and high tenacity nylon-6 fiber web blended with low-melt polyester staple fibers to form a compound nonwoven fabric with a sandwich structure processed by needle punching and thermal pressing. The compound nonwoven fabric was layered with Kevlar fabric to form bullet-resistant complex fabrics. Impact properties and buffer effect were analyzed via the drop weight impact test and the bullet-shooting test. The compound nonwoven fabrics made of high-tenacity nylon-6 fiber and 3D crimped hollow fiber increased the buffer effect of ballistic resistance and decreased non-penetration damage and the layer of Kevlar fabrics. This study was expected to increase the safety of the ballistic resistant cloth and decrease its cost.
