In this study, we laid the spread polyester filament on the pre-punching polyamide web with low melted polyester staple fibers to form sandwich structure by the covering of another web. After the bonding of needle punching and thermal calendar, we got the compound nonwoven fabrics. The original cushion material of the bulletproof vest was replaced with the compound nonwoven fabrics. We evaluated the buffer effect of the compound nonwoven fabrics in the bulletproof complex fabrics by the deformation of the backing material in the shooting test of bullet. We changed the content of low melted polyester staple fibers, needle punching density and the content of polyester filament to discuss the influences of these parameters on the buffer effect of the compound nonwoven fabrics in bulletproof complex fabrics. We expected that the compound nonwoven fabrics were superior to original cushion material of bulletproof vest in cushion effect.
