In order to study the reaction of vinyl monomers onto the silk fibers, some reactive dyes, such as C.I.Reactive Blue 19, C.I.Reactive Red 6, and C.I.Reactive Red 120 were applied to silk dyeing. The dyed silk fiber was grafted with MAA(Methacrylamide)...
In order to study the reaction of vinyl monomers onto the silk fibers, some reactive dyes, such as C.I.Reactive Blue 19, C.I.Reactive Red 6, and C.I.Reactive Red 120 were applied to silk dyeing. The dyed silk fiber was grafted with MAA(Methacrylamide) and HEMA(2-Hydroxyethyl-methacrylate).
The grafting yield was evaluated by weighting and the change of dyeing property is investigated by shade variation. The results obtained are as follows;
1. In the MAA graft polymerization the weight increase of dyed silk samples indicated the presence of less polymer than un-dyed silk samples.
However, the dyed silk samples with Reactive Blue 19 was not shown the homogeneous distribution of polymer onto the fiber.
2. In the HEMA graft polymerization the weight increase of dyed silk samples with Reactive Red 6 was higher value, the Reactive Red 120 nearly same value, and the Reactive Blue 19 was less value than that of undyed silk samples.
3. In the processing of graft polymerization the desorption of dyes from fiber was not observed and the shade variation was nearly not observed in accordance with the graft polymerization.
