Embodiment 1

[0020] A production method of polyester industrial yarn for marine cables according to the present invention, which includes extrusion melting, metering, slow cooling, side blowing cooling, first oiling, five pairs of rollers stretching and setting, second oiling, winding forming;

[0021] The extrusion melting: using high-viscosity slices with a viscosity of 1.05, heating and extrusion melting through six screw zones, the heating temperature of each zone of the screw is 312°C in the first zone, 308°C in the second zone, 302°C in the third zone, and 294°C in the fourth zone. The fifth zone is 293°C, the sixth zone is 292°C, the temperature is lowered zone by zone, and then heated;

[0022] The metering: use a 30cc / rpm metering pump to control the outlet melt temperature to 300°C;

[0023] The slow cooling: the metering pump sends the melt quantitatively to each spinning assembly, sprays it out through the spinneret holes, and then heats and cools slowly at a temperature of 31...

Abstract

The invention relates to a production method of polyester industrial yarn for marine cables. The production method comprises the steps of extruding and melting, metering, slow cooling, lateral blowingand cooling, primary oil applying, stretching and shaping of five pairs of rollers, secondary oil applying, and winding and molding. The finished product produced by the production method provided bythe invention is high in strength, light in weight, soft and good in sea water corrosion resistance and wear resistance.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a production method of polyester industrial yarn. Background technique [0002] Traditional marine cables are generally steel wire ropes, which have poor corrosion resistance and are prone to rust in seawater environments. In recent years, with the rapid development of marine economy, the application of marine textiles in the market has increased rapidly, making the market prospect of industrial yarn for marine cables more and more broad. Ordinary high-strength polyester industrial yarn is easily aged and has a short service life due to the influence of light, salt, bacteria and other factors in the seawater environment. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to overcome the deficiencies in the prior art and provide a production method of polyester industrial yarn for marine cables with high strength, light wei...
