“…In recent years, there has been a surge in industry interest in using microencapsulation processes to develop innovative materials. Microencapsulation has various benefits and advantages since active substances, such as vitamins, scents, essential oils, biocides, and drugs, may be encapsulated to preserve them from environmental factors, increase their temperature resistance, control the release rate of the additive encapsulated, or make liquids compatible with solids [ 1 , 2 , 3 , 4 ]. In the textile sector, microencapsulation offers many opportunities to improve the properties of textiles and provide new functionalities.…”

The development of capsules with additives that can be added to polymers during extrusion processing can lead to advances in the manufacturing of textile fabrics with improved and durable properties. In this work, caffeine (CAF), which has anti-cellulite properties, has been encapsulated by liquid-assisted milling in zirconium-based metal–organic frameworks (MOFs) with different textural properties and chemical functionalization: commercial UiO-66, UiO-66 synthesized without solvents, and UiO-66-NH2 synthesized in ethanol. The CAF@MOF capsules obtained through the grinding procedure have been added during the extrusion process to recycled polyamide 6 (PA6) and to a biopolymer based on polylactic acid (PLA) to obtain a load of approximately 2.5 wt% of caffeine. The materials have been characterized by various techniques (XRD, NMR, TGA, FTIR, nitrogen sorption, UV–vis, SEM, and TEM) that confirm the caffeine encapsulation, the preservation of caffeine during the extrusion process, and the good contact between the polymer and the MOF. Studies of the capsules and PA6 polymer+capsules composites have shown that release is slower when caffeine is encapsulated than when it is free, and the textural properties of UiO-66 influence the release more prominently than the NH2 group. However, an interaction is established between the biopolymer PLA and caffeine that delays the release of the additive.

“…In microencapsulation processes with alginate as a polymer, gel formation occurs immediately after contact with the receiving ion solution, and the process itself is therefore simple, carried out in mild and nontoxic conditions, and does not require complicated devices, which is why alginate is widely used for microencapsulation methods [ 5 ]. In addition to alginate, other biopolymers such as chitosan, gelatin, or cellulose can be used [ 6 , 7 ] and their choice depends on their adsorption and desorption properties for a given molecule, as well as their behavior during gelation.…”

The aim of this work was to analyze and compare the adsorption and desorption processes of carbohydrates (glucose as a model molecule), polyphenols (gallic acid as a model molecule), and proteins (bovine serum albumin, BSA as a model molecule) on alginate microcapsules. The adsorption and desorption processes were described by mathematical models (pseudo-first-order, pseudo-second-order, and Weber–Morris intraparticle diffusion model for adsorption, and first-order, Korsmeyer–Peppas, and the Higuchi model for desorption) in order to determine the dominant mechanisms responsible for both processes. By comparing the values of adsorption rate (k2) and initial adsorption rate (h0) based on the pseudo-first-order model, the lowest values were recorded for BSA (k1 = 0.124 ± 0.030 min−1), followed by glucose (k1 = 0.203 ± 0.041 min−1), while the model-obtained values for gallic acid were not considered significant at p < 0.05. For glucose and gallic acid, the limiting step of the adsorption process is the chemical sorption of substances, and the rate of adsorption does not depend on the adsorbate concentration, but depends on the capacity of the hydrogel adsorbent. Based on the desorption rates determined by the Korsmeyer–Peppas model (k), the highest values were recorded for gallic acid (k = 3.66236 ± 0.20776 g beads/mg gallic acid per min), followed by glucose (k = 2.55760 ± 0.16960 g beads/mg glucose per min) and BSA (k = 0.78881 ± 0.11872 g beads/mg BSA per min). The desorption process from alginate hydrogel microcapsules is characterized by the pseudo Fickian diffusion mechanism.

The key to achieving sustainable development lies in reducing waste, valorizing waste, and adopting conscious consumption. This study aimed to evaluate the potential of two by-products from the cork industry as natural dyes for textiles. Specifically, cork-cooking wastewater and expanded black cork condensate were tested as eco-friendly coloring agents to dye cotton (both organic and with a surface treatment) and wool. After dyeing, the colored fabric samples were subjected to washing with hot and cold water, as well as natural light exposure, to assess color fastness. The color assessment at the end was performed using ΔE*, which is a parameter that quantifies the magnitude of a color difference, comparing the L*a*b* color coordinates from the CIELAB system of the dyed samples with those of the control sample. The magnitude of ΔE* (>5) showed that, in all cases, the fabric samples exhibited a different color from the controls. However, the best coloring performance was achieved with expanded black cork condensate in wool samples, resulting in a uniform dark brown color (ΔE* = 42.48 ± 0.19). Additionally, the cationized cotton samples showed an interesting brownish-grey hue (ΔE * = 35.02 ± 0.42), indicating that the surface treatment promoted dye fixation, since the organic cotton achieved only a light brown color (ΔE * = 14.52 ± 0.39) and was less resistant to light exposure. Natural dyeing using cork extract presents a sustainable, eco-friendly, and non-toxic alternative for textile dyeing. Furthermore, the observed bacteriostatic effect indicates the potential for producing functionalized colored textiles with great interest in medical applications. The process results in unique and earthy tones while promoting the sustainable use of natural resources and preserving the environment.
