Challenges in Wool Fiber Dyeing

Abstract

This paper reviews the analysis of some properties of wool fiber and its dyeing challenges that can influence the outcomes of dyeing. It is relatively intricate to acquire the true color and the main source of a given problem is even more challenging. Its complexity is demonstrated by the different important chemical groups it has and the intermolecular forces of attraction between the linkages, the environmental demands on dyeing process, varied application areas, different important chemical groups present in the chain, fiber damage and permanent setting, presence of non-keratinous Proteins and due to the preparatory pretreatment process .Some approaches that could lead to progress in wool dyeing are discussed in this review and some alternative strategies are also proposed.
