In the current work, synthetic polyamide nylon fibers were modified via the strategy of surface molecular imprinting to develop enantio-selective adsorbent fabrics for chiral recognition of D-phenyllactic acid (D-PhLA). The nylon fibers were first modified by grafting of polyacrylamide and then the incorporated amide groups were converted into functional amino groups via treatment with NaOCl (Hofmann degradation). The amino-functionalized nylon fibers (Ny-NH 2 ) were interacted with the targeted D-PhLA enantiomer before crosslinking the amino-containing grafted chains with glutaraldehyde crosslinker followed by leashing the template D-PhLA out of the formed surface polymeric matrix by lowering the pH to 1 to finally produce the desired enantio-selective adsorbent fibers DP-Ny. Different instrumental methods such as elemental analysis, Fourier transform infrared spectroscopy, XRD and TGA were employed to examine all the synthetic procedures. SEM was also utilized to observe the morphological appearances of both native and modified nylon fibers. Moreover, the optimum extraction of D-PhLA was found to occur at pH 7. Isotherm studies of the prepared DP-Ny fibers obeyed the common Langmuir linear equation with q m values 130 ± 2 and 75 ± 1 mg g −1 in the case of D-PhLA and L-PhLA, respectively. Furthermore, the enantiomeric resolution of (±)-PhLA racemate was successfully carried out by a column technique with enantiomeric excess reaching approximately 78%.

“…Radiation-induced graft polymerization (RIGP) is an advanced technique that is mainly used for the surface modification of traditional polymers. − In recent studies, nonconjugated and AIE-based polyethylene/polypropylene nonwoven fabric (PE/PP NWF) was prepared via RIGP. Herein, for the first time, ACQ-based pyrene (Py) units were covalently connected to the surface of PE/PP NWF via RIGP followed by chemical modification.…”

Conventional aromatic compounds tend to exhibit the formation of sandwich-shaped excimers and exciplexes between their excited and ground states at high concentrations or in their aggregated states, causing their fluorescence to weaken or disappear due to the aggregation-caused quenching (ACQ) effect. This limits their applications in concentrated solutions or solid materials. Herein, for the first time, ACQ-based pyrene (Py) units are covalently connected to the surface of polyethylene/polypropylene nonwoven fabric (PE/PP NWF) via electron beam preradiation-induced graft polymerization followed by chemical modification. The matrix can be considered a solid solvent and Py units as a solid solute, such that the amount of Py units can be controlled by varying the reaction time. The obtained fluorescent fabric not only exhibits remarkable fluorescence properties with high fluorescence intensity, high quantum yield (>90%), and excellent fluorescence stability after laundering or in harsh chemical environments, but the fluorescence color and intensity, quantum yield, and lifetime can also be regulated by employing the ACQ effect. Additionally, the as-prepared fluorescent fabric can effectively distinguish common monocyclic aromatic hydrocarbons via a simple fluorescence response test.

“…Antibacterial polyamide fiber can be produced using two ways: the addition of inorganic antibacterial agents (e.g., silver and zinc oxide nanoparticles) into polyamide during fiber spinning [7,8], and the treatment of polyamide fiber using antibacterial agents in wet processing [9,10,11,12,13]. Because of the processing convenience, the latter is most often adopted.…”

“…Because of the processing convenience, the latter is most often adopted. The antibacterial agents used in wet processing include cationic non-surfactant and surfactant agents (e.g., chlorhexidine, cetylpyridinium chloride) [9,10], chitosan [11], silver nanoparticles [12], and metal salts [13]. However, the aforementioned antibacterial agents cannot impart antioxidant properties to polyamide fiber.…”

Polyamide fiber has the requirements for antioxidant and antibacterial properties when applied to produce functional textiles for heath care purposes. In this work, three natural flavonoids (baicalin, quercetin, and rutin) were used to simultaneously impart antioxidant and antibacterial functions to polyamide fiber using an adsorption technology. The relations of the chemical structures of flavonoids with their adsorption capability, adsorption mechanisms, and antioxidant and antibacterial activities were discussed. The Langmuir–Nernst adsorption model fitted the adsorption isotherms of the three flavonoids well. The adsorption kinetics of the three flavonoids conformed to the pseudo second-order kinetic model. Quercetin exhibited the highest affinity and adsorption capability, and imparted the highest antioxidant and antibacterial activities to polyamide fiber; and moreover, its antioxidant and antibacterial functions had good washing durability. This study demonstrates that the treatment using natural flavonoids is an effective way to exhance the health care functions of polyamide fiber.
