| titleOfInvention | Polyester industrial yarn for cable and preparation method therefor |
| abstract | The present invention relates to a polyester industrial yarn for a cable and a preparation method therefor. The method comprises subjecting a modified polyester to solid-phase polycondensation and tackifying, followed by spinning and winding same and subjecting same to a coordination treatment to obtain the polyester industrial yarn, wherein the coordination treatment involves soaking the wound fiber into an aqueous solution of a coordination agent, wherein the aqueous solution of a coordination agent has a concentration of 0.1-0.2 mol/L, the conditions of the coordination treatment are at 80-100°C for 60-72 h, and the coordination agent is NiCl 2 . Polyester chain segments of the prepared polyester industrial yarn for a cable comprise a terephthalic acid chain segment, an oxalic acid chain segment and a 2,2-bipyridine-4,4-dicarboxylic acid chain segment, and 2,2-bipyridine-4,4-dicarboxylic acid chain segments of different polyester chain segments are coordinated by means of Ni 2+ . The molar ratio of the terephthalic acid chain segment to the 2,2-bipyridine-4,4-dicarboxylic acid chain segment is 1 : 0.03-0.05, and the N atom on the pyridine and the O atom on the carbonyl in the 2,2-bipyridine -4,4-dicarboxylic acid chain segment participate in coordination. In the present invention, by means of Ni(II)-pyridine coordination, the adhesive force of the contact surface caused by mutual diffusion generated by molecular chain sliding in the friction process of polyester is reduced, such that the friction resistance of the polyester industrial yarn is improved. |
