“…Using the special composition of coagulation bath in the wetspinning technique, one can obtain a range of different alginate fibers incorporating copper, sodium, or calcium or fibers made of alginic acid. Currently, alginate fibers are widely applied in medicine, primarily as dressing materials [6][7][8][9][10][11][12]. Due to their swelling and gelling properties, such dressings do not adhere to the wound and can easily be removed.…”

The results of studies assessing the influence of the addition of carbon nanofillers, such as multiwalled carbon nanotubes (MWCNTs) and graphene oxide (GO) that differ in size and structure, on the molecular and supramolecular structure and properties of alginate fibers that might be prospective precursors for carbon fiber (PCF) industry are presented in this article. The investigation was carried out by Fourier transform infrared (FTIR) spectroscopy, wide-angle X-ray diffraction (WAXD), and tension testing. In the frame of the current study, two types of alginate fibers were examined and compared: alginic acid and calcium alginate fibers. Alginic acid fibers were formed by chemical treatment of calcium alginate fibers with hydrochloric acid due to the fact that Ca2+ ions presented in the fibers were expected to adversely affect the prospective carbonization process. This investigation brought important conclusions about the influence of nanofillers on the physical properties of the final material. Understanding the link between the incorporation of carbon nanostructures and a possible influence on the formation of ordered carbon structures in the precursor fibers brings an important opportunity to get insights into the application of alginate fibers as a prospective base material for obtaining cost-efficient carbon fibers.

“…One of the goals of the modification is to improve the properties of functional clothing parameters, affecting the safety of a selected group of users working in extremal environmental conditions like firefighters, rescuers, steel workers [ 26 , 27 , 28 , 29 , 30 ] as well as soldiers and policemen [ 31 , 32 , 33 , 34 , 35 , 36 ]. Surface modification is also commonly used in garments with healing properties [ 37 , 38 , 39 , 40 , 41 , 42 ] as well as smart clothing textiles that monitor the user’s life processes [ 43 , 44 , 45 , 46 , 47 , 48 ]. Surface modification is also commonly used for decorative clothing purposes [ 49 , 50 , 51 , 52 , 53 ].…”

This article presents research on the assessment of the impact of surface modification of cotton and polyester fabrics using four techniques (flocking, layer by layer, screen printing and thermal-transfer printing) on their structural, mechanical, biophysical, and sensory properties. Depending on geometry and raw materials of the fabrics, the clothing made of them it is characterized by certain biophysical properties which are intended to protect the human body against external factors, but also against excessive sweating and overheating or cooling down. The aforementioned properties of the modified textiles were determined with: optical microscopy, microcomputed tomography, a tensile testing machine, sweating guarded-hotplate, air permeability tester, and the Kawabata evaluation system. Based on analysis of obtained results, it can be concluded that flocking reduces air permeability the most (−77% for cotton fabric and −99.7% for polyester fabric), and total hand value (−58% and −57%) and increases water vapor resistance the most (+769% and +612%) while the screen printing increases the thermal resistance the most (+119% and +156%) compared to unmodified textiles. It can be concluded that, when modifying textile substrates, the area of modification and their size on clothing products should be carefully selected so as not to adversely affect the feelings of potential wearers.

“…Exceeding the range of the 10% concentration results in a significant increase in the apparent dynamic viscosity, which results in an unstable spinning process. In order to obtain a spinning Materials 2022, 15, 4321 2 of 12 solution of the desired physicochemical properties, the apparent dynamic viscosity should maintained between 30 and 60 Pa•s, which ensures stable fibre formation [18,19]. Viscosity is also related to temperature-an increase of one degree Celsius causes a decrease in viscosity of up to 2.5%.…”

The Interphase Gas-Solid Synthesis of Ammonium Alginate—The Comparison of Two Synthesis Methods and the Effect of Low Molecular Weight Electrolyte Presence

This paper presents a method for the synthesis of ammonium alginate by interphase gas-solid reaction. It was confirmed by FTIR ATR spectroscopy analysis that a full substitution of acid groups by ammonium groups on the surface of powdered alginic acid was performed. Comparative studies on the properties of ammonium alginate solutions obtained by interphase reaction with those prepared by the classical method of dissolving alginic acid in an ammonia solution showed that the rheological properties of the solutions from these two derivatives do not differ significantly. Moreover, it was shown that aqueous solutions of ammonium alginate are more stable over time than solutions of sodium alginate. It was confirmed that ammonium alginate and sodium alginate are typical polyelectrolytes, as the addition of a low molecular weight electrolyte to their solutions resulted in a decrease in viscosity.
