Abstract:	In this study, high-resilience bonding polyester/Poly-paraphenylene terephthalamid intra-ply hybrid nonwovens with various fiber blending ratios and thermal treatment conditions were prepared through needle-punching and thermal bonding. The mechanical characteristics including tensile strength, tear strength, puncture resistance and bursting strength were investigated. The results showed that the addition of Kevlar fibers enhanced the mechanical properties of hybrid nonwovens. The tensile strength, puncture resistance and bursting strength also improved with the increase in thermal treatment duration and temperature while the tear strength had lower strength when treated at 180°C than at 170°C. The reason was thermal bonding points restricted the slippage of the fibers leading the fibers to break in sequence instead of sustaining the tension together.
