| Abstract: | PET tire cord was prepared from 1 100 dtex PET technical yarn by twisting on a direct twisting machine. The compound-twist tire cord with breaking strength higher than 145 N and the irregularity of breaking strength and elongation at break less than 1％ can be produced under the conditions of spindle speed 8 000 r/min, number of twists 440 T/m,outer yarn tension 65％ , overfeed ratio 5％ and pattern breaking angle (20±1) °. The direct twisting process yielded product quality and economic benefit much higher than second-twisting process. |
