ADVANCED RESEARCH OF RUCO-FLAME SCO AS A VOGNEZOHIS COMPONENT IN ENVIRONMENTALLY ORIENTED TECHNOLOGIES FOR THE PRODUCTION OF HEMP TISSUE

Abstract

This study provides a theoretical substantiation for using the environmentally friendly phosphorus-nitrogen preparation RUCO-FLAME SCO to impart flame retardant properties to cellulose-containing hemp fiber. The relevance of this research is driven by increasing interest in the use of natural fibers and ensuring human life safety, as well as limited literature on the use of modern flame-retardant systems for textile materials made from hemp fibers. In contrast to conventional flame-retardant treatments, which often result in poor adhesion, reduced strength, and environmental restrictions, the use of RUCO-FLAME SCO provides a gentle, technologically compatible, and environmentally safe finishing process. The conducted studies have established that RUCO-FLAME SCO is an effective flame retardant for treating cellulose hemp fabrics for footwear. Finishing fabrics with RUCO-FLAME SCO during vertical combustion tests ensures self-extinguishing of hemp textiles, limiting flame spread, as evidenced by a reduction in char length and the absence of smoldering and afterglow. The flame-retardant effect remains wash-resistant due to the hydrogen and ion-dipole interactions of the flame retardant with the hydroxyl groups of cellulose and physical immobilization in the amorphous zones of the fiber. The addition of β-cyclodextrin and Neoprint PNA/S acrylic aqueous dispersion to the finishing bath further enhances the stability of the flame-retardant effect and improves the physical and mechanical properties of hemp fabric intended for footwear. The obtained results demonstrate the effectiveness of using RUCO-FLAME SCO as a basic flame-retardant component in environmentally oriented technologies for treating hemp fabrics with flame-retardant compounds and confirm the potential for further research aimed at optimizing its fixation mechanisms and increasing the resistance of the finish to physical and chemical influences, which will expand the range of functional hemp materials for special protective footwear.
