Abstract

This article examines the production technology of polypropylene-based synthetic yarns used in carpet weaving and methods for improving their fire resistance. Despite the excellent physical and mechanical properties of polypropylene fibers, particularly their wear resistance and strength, as well as their cost effectiveness, one of their major drawbacks is flammability. Therefore, modifying the fiber composition with flame retardant additives and optimizing process parameters is discussed. During the study, carbon-, silicon dioxide-, and aluminum oxide-based flame retardants were added to the polypropylene melt, producing threads of varying densities. Thread quality was determined separately at the extrusion, stretching, texturing, and heat-setting stages. Based on the experimental results, patterns in the change in combustion time and temperature with increasing thread density were determined. Sample No. 4, containing 92.7% polypropylene, 3% carbon, 0.3% SiO₂, 1% Al₂O₃, 1% plasticizer, and 2% dye, was found to be the most effective flame-retardant material. The proposed technology improves the fire resistance of carpet threads and enhances their operational safety. Furthermore, the proposed technological composition and stable production process improve the quality of the finished product. These results will serve as the basis for the production of safe, durable, and competitive products in the carpet industry.
