“…Both dyes and pigments are used in the coloration of textiles [1,2]. The former substances are present in solution at some point during their application, whereas the latter colorants remain insoluble within any vehicle in which they are applied as well as within the textile material itself [3].…”

“…A useful way of grouping textile colorants into sets with very broadly similar characteristics in terms of color, usage, fastness and economy is by CI application class. The most important application classes of textile colorant are listed in Table 1 and described in more detail below [1,2,5,[7][8][9][10].…”

“…This type of anionic colorant is commonly used to dye and print natural (wool, silk) and synthetic (nylon) polyamides [2,5,[7][8][9][10]. The class is named after the acidic (pH 2-6) dyebaths used for dye application.…”

“…Members of this class are used primarily for coloration of polyacrylonitrile, either by exhaustion dyeing or during fiber production [2,5,7]. They are often referred to as cationic dyes because their molecular structures feature a positive charge as shown for example in Fig.…”

“…This class is so named because its members can be applied to cotton and other cellulosic fibers without the need for mordants [2,5,7]. The crucial molecular features of direct dyes are (a) long, linear planar geometries and (b) multiple substitution with negatively-charged sulfonic acid groups as depicted in Fig.…”

Textile colorants impart color to a textile material, usually with a high degree of permanency, as a result of their chemical binding or physical entrapment within or around the textile material. The textile material may be in one of several forms such as fiber, yarn, fabric, garment, etc. Textile colorants are supplied in both solid and liquid forms, for example, as powders, granules, solutions, or dispersions. In certain instances, precursors are applied to textile materials to generate the colorant in situ within the textile.

Biopolymeric chitosan is considered a promising encapsulating agent for textile applications due to its biocompatibility, lack of toxicity, antibacterial activity, high availability, and low cost. After cellulose, it is nature's most important organic compound. Also, chitosan has unique chemical properties due to its cationic charge in solution. Microencapsulation technologies play an important role in protecting the trapped material and in the durability of the effect, controlling the release rate. The application of chitosan microcapsules in textiles follows the current interest of industries in functionalization technologies that give different properties to products, such as aroma finish, insect repellency, antimicrobial activity, and thermal comfort. In this sense, methods of coacervation, ionic gelation, and LBL are presented for the production of chitosan-based microcapsules and methods of textile finishing that incorporate them are presented, bath exhaustion, filling, dry drying cure, spraying, immersion, and grafting chemical. Finally, current trends in the textile market are identified and guidance on future developments.
