“…The classical textile pre-treatment processes of desizing, scouring and bleaching, which are crucial for making textiles suitable for adsorption of microcapsules, textile auxiliaries, dyes and pigments, need to be changed towards the use of environmentally friendly chemicals such as amylases, pectinases and hydrogen peroxide [205,206]. Functionalization of textiles can be achieved using classical finishing agents and methods without or with microcapsules to provide water and oil repellent, flame retardant or antimicrobial properties.…”

Microencapsulation for Functional Textile Coatings with Emphasis on Biodegradability—A Systematic Review

2021

View full text Add to dashboard Cite

The review provides an overview of research findings on microencapsulation for functional textile coatings. Methods for the preparation of microcapsules in textiles include in situ and interfacial polymerization, simple and complex coacervation, molecular inclusion and solvent evaporation from emulsions. Binders play a crucial role in coating formulations. Acrylic and polyurethane binders are commonly used in textile finishing, while organic acids and catalysts can be used for chemical grafting as crosslinkers between microcapsules and cotton fibres. Most of the conventional coating processes can be used for microcapsule-containing coatings, provided that the properties of the microcapsules are appropriate. There are standardised test methods available to evaluate the characteristics and washfastness of coated textiles. Among the functional textiles, the field of environmentally friendly biodegradable textiles with microcapsules is still at an early stage of development. So far, some physicochemical and physical microencapsulation methods using natural polymers or biodegradable synthetic polymers have been applied to produce environmentally friendly antimicrobial, anti-inflammatory or fragranced textiles. Standardised test methods for evaluating the biodegradability of textile materials are available. The stability of biodegradable microcapsules and the durability of coatings during the use and care of textiles still present several challenges that offer many opportunities for further research.

“…In that regard, biotechnology emerges as a tool capable of increasing food security and productivity by occupying less area. In addition, it reduces greenhouse gas emissions through more sustainable technologies for energy and food production, biofuel production, and bioremediation, among others [ 7 , 8 , 9 , 10 , 11 , 12 ]. This way, biotechnology is considered a meaningful way to revert the current environmental crisis scenario [ 13 , 14 ].…”

Human population growth, industrialization, and globalization have caused several pressures on the planet’s natural resources, culminating in the severe climate and environmental crisis which we are facing. Aiming to remedy and mitigate the impact of human activities on the environment, the use of lignocellulolytic enzymes for biofuel production, food, bioremediation, and other various industries, is presented as a more sustainable alternative. These enzymes are characterized as a group of enzymes capable of breaking down lignocellulosic biomass into its different monomer units, making it accessible for bioconversion into various products and applications in the most diverse industries. Among all the organisms that produce lignocellulolytic enzymes, microorganisms are seen as the primary sources for obtaining them. Therefore, this review proposes to discuss the fundamental aspects of the enzymes forming lignocellulolytic systems and the main microorganisms used to obtain them. In addition, different possible industrial applications for these enzymes will be discussed, as well as information about their production modes and considerations about recent advances and future perspectives in research in pursuit of expanding lignocellulolytic enzyme uses at an industrial scale.

“…Carboxylesterases are prevalent in nature [ 4 ]. Of all sources, bacterial carboxylesterase is the main biocatalyst used in practical applications, such as in the production of detergent, textile, paper and the synthesis of optically purified compounds [ 5 , 6 , 7 , 8 ]. Despite this versatility, the applied free enzyme generally displays poor stability against high temperature, pH, and some chemical reactions, such that environmental circumstances can alter its conformation, leading to either reversible or irreversible deactivation.…”

Carboxylesterase has much to offer in the context of environmentally friendly and sustainable alternatives. However, due to the unstable properties of the enzyme in its free state, its application is severely limited. The present study aimed to immobilize hyperthermostable carboxylesterase from Anoxybacillus geothermalis D9 with improved stability and reusability. In this study, Seplite LX120 was chosen as the matrix for immobilizing EstD9 by adsorption. Fourier-transform infrared (FT-IR) spectroscopy verified the binding of EstD9 to the support. According to SEM imaging, the support surface was densely covered with the enzyme, indicating successful enzyme immobilization. BET analysis of the adsorption isotherm revealed reduction of the total surface area and pore volume of the Seplite LX120 after immobilization. The immobilized EstD9 showed broad thermal stability (10–100 °C) and pH tolerance (pH 6–9), with optimal temperature and pH of 80 °C and pH 7, respectively. Additionally, the immobilized EstD9 demonstrated improved stability towards a variety of 25% (v/v) organic solvents, with acetonitrile exhibiting the highest relative activity (281.04%). The bound enzyme exhibited better storage stability than the free enzyme, with more than 70% of residual activity being maintained over 11 weeks. Through immobilization, EstD9 can be reused for up to seven cycles. This study demonstrates the improvement of the operational stability and properties of the immobilized enzyme for better practical applications.
