Acting mechanism of carrier Cindye Dnk on aramid fibers

In order to reveal the mechanism of carrier Cindye Dnk on aramid fibers, the influence of carrier Cindye Dnk on the structure and properties of aramid fibers was studied with modern analytical methods such as TGA, XRD, FTIR, SEM, OM and etc. The results showed that the carrier Cindye Dnk didn’t affect the surface morphology and chemical structure of aramid fibers. The chemical structure of carrier Cindye Dnk was similar to that of aramid fibers, thus it conformed to the rule of like dissolves like, and the carrier Cindye Dnk had a good swelling effect on aramid fibers, making the thermal and physical properties of aramid fibers enhanced slightly without affecting their internal crystal structure and flame retardant property. Moreover, Cindye Dnk improved significantly the dyeability of aramid fibers, and increased the diameter, cross sectional area, and porosity.
