Nano Surface Finishing on Aramid High Performance Fabric to Improve Its Anti UV Degradation Property
Nomex, developed by Du Pont in the early 1960s, is a flame resistant meta-aramid material. Its molecular structure composed of the aromatic rings and the conjugated amide bonds is particularly strong and resistant to chemical attack. At least 85％ of the amide linkages are attached directly to two aromatic rings, which provide a high degree of heat resistance to the polymer backbone1. Nomex material is widely used in industry, military and firefighting circumstance for its excellent performance in tenacity, modulus, dimensional stability and heat resistance. But Nomex fibres degrade severely under ultraviolet radiation both from natural and artificial light. The tensile strength of Nomex fibre retained 65％ after 96 hours continuous exposure to light of 360nm wavelength 2. Discoloration of Nomex fibre occurred with the strength loss. The strength loss caused by UV degradation may restrict the practical application of Nomex material. The purpose of this study is to search an effective method to protect the aramid high performance fabric from UV degradation.
