Summary: Ionic liquids offer alternative methods for the processing of natural biopolymers like chitosan. In this study, 1-butyl-3-methylimidazolium acetate (BmimOAc) was used as a solvent to manufacture pure chitosan-based monofilaments through a wet spinning process. The study provides valuable knowledge for the development of wet spinning process and manufacturing of pure chitosan fibers.

Summary: Cellulose, the most abundant and green biomass resource on earth, has gained significant attention as an alternative to traditional chemical and petroleum resources. This review discusses the various solvents used in industrial processes, including traditional solvents, non-derivative organic solvents, and aqueous solution systems, as well as their dissolution mechanisms and advancements in fiber-spinning processes. The challenges associated with industrial production of viscose fibers and cuprammonium fibers are also addressed. The focus of this paper is on the research status of regenerated cellulose fibers (RCFs) prepared using environmentally friendly and non-polluting aqueous solutions, and it provides strategies and methods for improving the mechanical strength of RCFs and facilitating industrial production. Finally, the current developments of RCFs are summarized and future research directions are proposed, serving as a guide for the future trends in RCFs.

Summary: In this study, spectrally selective fabrics for all-day low-temperature cooling were developed using a simple wet-spinning technique. The fabrics exhibited high reflectivity in the solar window and high infrared emissivity within the atmospheric transparency window, making them suitable for effective radiative cooling. Additionally, the fabrics showed great cloth comfort due to their physical properties.

Summary: In this study, Mn-Fe LDH/CS composite was successfully prepared and used for the simultaneous removal of IC and SY dyes. The first order derivative spectrophotometric method was applied to measure IC and SY simultaneously, and the pseudo second order model was found to be the best fitting model under the optimum conditions. The adsorption isotherm of dyes followed the Langmuir isotherm model.

Summary: CS fibers with enhanced mechanical properties and a hierarchical structure were successfully prepared through wet spinning of CS/SNFs composite fibers. The addition of SNFs significantly improved the mechanical properties of CS fibers, with the tensile strength and modulus increased by 2.9 times and 3.5 times, respectively, when 100% SNF was added. The enhancement of mechanical properties was attributed to the hydrogen bonding between SNF filaments and CS.

Summary: In this study, monofilaments were produced from the cell wall of Rhizopus delemar, a zygomycete fungus grown on bread waste. The monofilaments contained chitosan, chitin, and other carbohydrates, and showed significant antimicrobial activity against both Gram+ and Gram- bacteria. Furthermore, the monofilaments exhibited no cytotoxicity. These findings suggest that the fungal monofilaments could be utilized as sustainable biomedical textiles using abundant food waste.

Summary: The study found that the formation of PPy layers on chitosan fibers can improve electrical conductivity, and the performance of these layers depends on the polymerization conditions. Biocompatibility tests showed that chitosan-PPy composite films contain more viable cells compared to films made from pure chitosan solutions.
