ABSTRACTNomex fabric is irradiated by an Xe 2 * excimer UV lamp (172 nm). The influence of different irradiating times and atmospheres (nitrogen and air) on the properties of Nomex fabric has been studied. The results show that the wettability of Nomex fabrics greatly improves when irradiated for 2 minutes. The scanning electron microscope (SEM) photos denote that the surface of the irradiated Nomex fiber is etched and the degree of etching in nitrogen is more severe than that in air. The XPS measurement proves that the surface of the Nomex fibers, which is irradiated in nitrogen and in air, generates carboxyl and hydroxyl groups. The results also show that the adhesive strength of the Nomex/polyethylene composite is reinforced by the irradiation.

Optimization of high performance m‐aramid fiber with disperse dye containing high color strength

“…Due to these excellent properties, m‐aramid is widely used in aerospace and firefighting suits . M‐aramid fibers are also used in protective garments that are worn in antistatic working condition, racing wear, heat‐resistant clothes, gloves, sportswear, smelting, and oil refineries . In addition to these, it has many other applications in filter bags for the filtration of hot gas and home textiles like carpets, curtains and floor coverings …”

An Investigation Into the Effect of Different Parameters on the Dyeing of High-Performance M-Aramid Fiber and Its Optimization

“…M-aramid belongs to the aromatic polyamide family that contains high-performance characteristics such as high melting point, high strength, resistance to organic solvents, and high flame retardancy. These characteristics make this fiber well suited for high-performance protective and technical textiles (Preston & Hofferbert, 1979; Xie, Yang, Yan, & Yao, 2010). M-aramid, due to its nonflammable chemical structure, has many applications in the area of thermally resistant and fire-retardant textiles (Baeva, Manyukov, Sadova, Konovalova, & Negodyaeva, 2007; Hearle, 2001).…”
