Intrinsic Differences between Nylon 6 and Nylon 66 Industrial Fibers: Micromechanical and Molecular Analysis

摘要

In airdrop applications we noted significant performance advantages of nylon 6 over nylon 66. These advantages are noted in bending fatigue, abrasion resistance and retention of properties on repeated use. To explain this advantageous behavior of nylon 6 we carried out comprehensive morphological and micromechanical analyses. These in turn, provided a better understanding of the role of subtle structural differences between nylon 6 and nylon 66 in the performance of fabrics used in parachutes.
