## 1 Introduction
Currently, basalt fibers are produced in the form of filaments that are not harmful to humans

The modification of basalt fabrics for use in protective gloves was conducted by the Central Institute for Labor Protection--National Research Institute in cooperation with the Lodz University of Technology. A project called \"Baglo\" was conducted, which involved developing and finding a new solution for protective gloves made of basalt fibers intended for use in hot workplaces. The developed protective gloves were made of basalt fabric and were intended for protection in a hot work environment. As a result of the tests, only one fabric was resistant to contact heat at a contact temperature of 250 \({}^{\circ}\)C. It was a fabric made of basalt fibers and aluminized on one side, with a thickness of 2.13 mm and a mass per unit area of 1307 g\(\cdot\)m\({}^{-2}\). This fabric was too thick for use in the palm part of the protective glove. In addition, the aluminum layer abraded and cracked at the seams during the fabrication process [2,16]. The subject and goal of the research presented in the current article were two composites with potential use in metallurgical gloves, which were developed on the basis of basalt fabric covered with two previously unused types of coatings (parylene C, TiO\({}_{2}\)-ZrO\({}_{2}\)-Al) in order to increase the insulation of the palm part of the gloves against contact heat at a contact temperature of 250 \({}^{\circ}\)C while maintaining high insulation against radiant heat. The first of the composites produced contained a coating of parylene C, the mer of which is shown in Figure 2.  
Parylene is the name used for the xylylene polymer family. These are polymers formed on the surface of the substrate by vacuum deposition polymerization. The advantages of parylene layers are low solubility, very good mechanical properties, high chemical resistance, and low permeability to gases and ions [20]. Parylene coatings provide maximum barrier protection due to their high cohesion [21]. The parylene coating reproduces the surface texture of the base material very well [22]. Moreover, the polymer based on poly-para-xylylene has a very low thermal conductivity [23]. Due to its availability and physicochemical properties, parylene C is the most frequently used (over 80%) type of parylene [24, 25, 26, 27, 28]. Parylene C is an organic coating without plasticizers, solvents, or catalysts with a controlled deposition layer thickness [20]. Additionally, it is characterized by specific properties for medical applications, e.g., low water absorption, low friction coefficient, high dielectric constant, and moderate elongation at break [21]. The variety of parylene C coatings makes them suitable for a wide range of applications. Parylene C also shows high biocompatibility, biostability, and the ability to produce a thin, continuous, and inert coating [22, 29]. In order to produce a second composite with ZrO\({}_{2}\)-TiO\({}_{2}\)-Al coatings deposited on its selected components using the physical vapor deposition (PVD) process, a mixture of zirconium dioxide (ZrO\({}_{2}\)), titanium dioxide (TiO\({}_{2}\)), and Al was used. ZrO\({}_{2}\) and TiO\({}_{2}\) were used because both ceramic materials belong to the group of thermal insulating coatings. Such coatings are primarily characterized by low thermal conductivity, a lack of transformation phase between the working temperature and room temperature, as well as good adhesion to the metallic substrate and chemical inertia. Titanium dioxide is mainly used in optics but also in cosmetics in the form of a mineral sunscreen filter, reflecting UV radiation, and in tissue engineering.
