Dyeing Behaviour of Unmodified and Modified Polyamide 6.6 Fibers of Different Levels of Fineness

Abstract:
In present study, the dyeing behaviour of unmodified and modified polyamide 6.6 fibers of different levels of fineness was investigated. The color strength of all the dyeings as well as their color fastness properties were studied. The obtained results revealed that with the use of acid or disperse dyes, color strength of dyeings decreased for microfibers compared to conventional fibers. Thus, the unmodified microfibers appeared to be more accessible to dyes than conventional ones, especially when small dye molecules were used. Both microfibers and conventional polyamide 6.6 fibers were modified with acrylic acid monomer using the free radical polymerization method. The dyeability of both modified fibers with basic dyes was significantly improved due to the incorporation of carboxylic groups. The consequences were an increase of color strength and an improvement of light fastness properties of basic dyeings by increasing the percent of graftings.
