Functional nonwoven products have superiority such as quick mass-production, short processing time, wide sources for raw material, low cost and high output etc. They have been widely studied and promoted in advanced countries. However, comparing with selvedge processing, they brings considerable burden to environment. So in this paper, we chose low cost polyester (LPE) and low melting point fiber (LMPE) respectively blending by 50 wt% through the process of mixing, blowing, carding, laying, and needle punching etc. to form nonwoven fabric in which the needle density was adjusted. Finally it is found that 103 needles/cm2 was optimal after mechanical testing. And then different proportions of PP selvedges were placed in the middle of two optimal nonwoven layers by sandwich structure, and mechanical properties of PET/LMPET/PP fabric produced after thermo bonding and cooling was tested. According to the optimal production evaluation for functionality, these products may apply to reinforced interlayer in general protective clothing, protective glove, reinforcement in simple building structure and stiffening geotextiles in the future.
