Abstract 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
-abstractable photoinitiator respectively. A UV energy of 35J/cm2 and a photoinitiator concentration of ten percent or more
with respect to the monomer in the formulation was required for optimal photografting. Grafting yield increased with higher
monomer application level. Surface analysis indicated significant alterations in the atomic composition of the photografted
fabric surface and the fabric surface was covered with the grafted polymers. While the pristine para-aramid fabrics showed
no appreciable dyeability to the α-bromoacrylamide reactive dyes, the grafted para-aramid fabrics enhanced the dyeability to
the reactive dyes substantially. In case of C.I. Reactive Blue 50, a K/S value of 8.7 can be obtained with the grafted
para-aramid fabrics with a grafting yield of 2.3 %. Also the color fastness properties of the dyed fabrics was excellent in
the conditions of washing, rubbing and light irradiation. |
