The application of aloe vera in textile processing is gaining worldwide detection as one of the hopeful approaches to pollution issues and cost reduction. Aloe vera gel possesses some biological activities and unique properties such as colorless, transparent, and viscosity which meet the using as a printing thickener, mordant, antimicrobial for different fabrics and dyes. Aloe vera is used in pre-treatment such as scouring, desizing, softening, and printing due to its succulent enzymatic and gummy characteristics. Aloe vera gel also contains a salty substance that allows its use in natural, eco-friendly dyeing. Aloe vera gel also is an alternative to synthetic antimicrobial agents.This state of art highlights the novel approaches of application of aloe vera in the textile coloration and industry covering both current types of research and pilot application.

“…The advantages of using biofunctional textiles are a high area of contact with the skin, drug loading capacity, ease of application, low price, release by stimulation, biocompatibility and being non-allergic and non-toxic, among other properties [ 13 , 14 , 15 ]. Thus, the choice of the active principle is of importance to the desired effect of the fabric.…”

In recent years, textile industries have focused their attention on the development of functional finishing that presents durability and, consequently, controlled release. However, in the case of methyl salicylate microcapsules supported on a textile matrix, studies indicate only the interactions between substrate and microcapsules and the drug delivery system, not applying the release equations. This study reports the mechanism and kinetics of controlled release of microcapsules of gelatin and gum Arabic containing methyl salicylate as active ingredient incorporated into textile matrices. According to the results presented, it was possible to verify that the wall materials participated in the coacervation process, resulting in microcapsules with well-defined geometry, besides promoting the increase of the thermal stability of the active principle. The samples (100% cotton, CO, and 100% polyamide, PA) functionalized with microcapsules released methyl salicylate in a controlled manner, based on the adjustment made by the Korsmeyer–Peppas model, indicating a Fickian mechanism. The influence of temperature was noticeable when the samples were subjected to washing, since with higher temperature (50 °C), the release was more pronounced than when subjected to lower temperature (37 °C). The results presented in this study indicate that the mechanism of backbone release is influenced by the textile matrix and by the durability of the microcapsule during the wash cycles.

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.
