Along with the continuous expansion of the application field of the aramid fiber, the color index of the aramid fiber is further required.
The aramid fiber is yellow, is aromatic polyamide fiber, and compared with aliphatic polyamide fiber such as polyamide 6 and polyamide 66 fiber, the aramid fiber macromolecular chain is replaced by a rigid benzene ring structure, more benzene rings are distributed on the aramid fiber macromolecular chain, the benzene rings are connected by amide bonds, and a large number of intermolecular hydrogen bonds exist, so that gaps among macromolecules are extremely small, dye is not easy to enter the inside of the molecules, and therefore the aramid fiber is difficult to dye by using a conventional method.
One of the currently available methods for dyeing aramid fibers is to mix a colorant into the polymer prior to the spinning process of the aramid fibers, however, this method can color the aramid fibers in their entirety, is costly and can contaminate the spinning equipment. The surface modification of the aramid fiber can be performed by using low-temperature plasma for treatment, but the method has higher cost and can cause the strong loss of the aramid fiber and influence the mechanical index of the aramid fiber rope. Dyeing aramid fiber with supercritical carbon dioxide fluid is also a feasible method, however, the method has high equipment requirement and cannot finish dyeing of various colors.
