Description

This review examines hybrid technologies combining dielectric barrier discharge (DBD) plasma treatment and sol-gel nanocomposite coatings to improve the performance of military textiles. The paper examines cotton/polyester (CO/PES) blended fabrics that exhibit good physicomechanical and comfort properties but limited thermal resistance. The reviewed literature identifies DBD plasma as an effective surface activation method that improves textile adhesion and chemical reactivity through the formation of active functional groups. The sol-gel silica matrix serves as a stable carrier for halogen-free phosphorus-nitrogen refractory systems and functional additives, contributing to improved limiting oxygen index (LOI) values and increased coating wash durability. In addition to fire protection, the reviewed studies demonstrate the potential for controlling spectral reflectance in the near-infrared (NIR) region by incorporating selected pigments, carbon-based materials, and metal oxide additives into the hybrid coating system. Such modifications can reduce the optical detectability of military textiles while maintaining the flexibility and comfort of the fabric. Based on the reviewed studies, the paper proposes a conceptual technological model for multifunctional military textiles with controlled spectral properties and improved thermomechanical performance. The review also outlines key performance indicators and future experimental directions for validating the proposed hybrid plasma-sol-gel concept on CO/PES military fabrics.
