Reactive Dyeing of Photografted para-Aramid Fabrics

open access: yesTextile Coloration and Finishing, 2011
para-Aramid has limited dyeability because of its highly crystalline structure and compactness. To improve the dyeability of the para-aramid to reactive dyes of bright color in deep shade, the fabrics were photografted under continuous UV irradiation with dimethylaminopropyl methacrylamide and 4-benzoyl benzoic acid as a monomer and a hydrogen ...

Ozone Effect On the Properties of Aramid Fabric [PDF]

open access: yesAutex Research Journal, 2017
Abstract The limitation of aramid fiber is its surface property, which results in its very poor interfacial adhesion to most of commercial resins. In order to improve the surface property of the aramid fiber, ozone treatment was carried out in this work.
