Experimental samples of knitted cords from new promising types of polyester yarns are obtained and their properties are investigated. Knitted cords made by rib interlooping on three or four needles and satin (tubular) stitches are chosen as the objects of the investigation. A distinctive feature of the cords from the new types of yarns is increased number of filaments. The investigations demonstrated that the cords made by satin stitch interlooping have a more uniform, filled, and smooth surface. The diameter of the cords knitted from various yarns of several plies, but of identical total linear density depends on the total number of filaments, i.e., the more the filaments, the greater the diameter. The linear density and breaking load of the cords made from various yarns with identical total linear density, but different number of filaments depends on the number of plies of the yarn rather than on the number of filaments. The parameters increase with the number of plies, whereupon breaking elongation also increases. It is recommended to use the obtained results for designing and knitting cords.
