preparation example Construction

[0015] The preparation method of polyethersulfone fiber core-spun rope comprises the following steps:

[0016] (1) Material selection: polyethersulfone fiber filaments are selected, and their specifications are 210D-1050D; the processing technology of the polyethersulfone fiber filaments is as follows: the polyethersulfone resin is dried by blowing, put into a twin-screw extruder Heating and melting at a temperature of 300-400°C, and then melting and extruding the filament through a spinning assembly with a temperature resistance temperature of at least 500°C. The extrusion temperature is 310-390°C to obtain surface-treated polyethersulfone fiber filaments, so that The fiber has excellent heat resistance, physical and mechanical properties, and insulation properties;

[0017] (2) Doubling: 3-6 polyethersulfone fiber filaments are combined into one strand for doubling;

[0018] (3) Twisting: After paralleling, the polyethersulfone fiber filaments are twisted into strands throu...

Embodiment 1

[0022] 1. Select raw materials: The selected raw materials are surface-treated polyethersulfone fiber filaments, and their specifications are 210D;

[0023] 2. Paralleling: 3 polyethersulfone fiber filaments are combined into one strand for paralleling;

[0024] 3. Twisting: After paralleling, the polyethersulfone fiber filaments are twisted through a twisting machine, and the transmission belt of the twisting machine is tight and tight. Each filament must be controlled by a tension regulator, and its speed and twist are measured regularly. Depending on the size of the rope strands;

[0025] 4. Pre-weaving: The strands twisted by the twisting machine are pre-woven on the automatic pre-looming machine into a bobbin that meets the spindle size of the high-speed weaving machine for weaving;

[0026] 5. Rope formation: Put the pre-woven bobbin on the spindle, and drive the spindle to rotate at high speed by starting the motor of the high-speed braiding machine. The rope sheath 1 ...

Embodiment 2

[0028] 1. Select raw materials: The selected raw materials are surface-treated polyethersulfone fiber filaments, and their specifications are 420D;

[0029] 2. Parallel line: 5 polyethersulfone fibers are combined into one strand for parallel line;

[0030] 3. Twisting: After paralleling, the polyethersulfone fiber filaments are twisted through a twisting machine, and the transmission belt of the twisting machine is tight and tight. Each filament must be controlled by a tension regulator, and its speed and twist are measured regularly. Depending on the size of the rope strands;

[0031] 4. Pre-weaving: The strands twisted by the twisting machine are pre-woven on the automatic pre-looming machine into a bobbin that meets the spindle size of the high-speed weaving machine for weaving;

Abstract

The invention discloses a polyether sulfone fiber compound rope and a preparation method thereof. The polyether sulfone fiber compound rope comprises a rope cover and a rope core, wherein the rope cover is formed by knitting part of polyether sulfone fiber strands in an S twisting direction and another part in a Z twisting direction; the rope cover is an outer sleeve body knitted from a plurality of polyether sulfone fiber strands which are formed by twisting a plurality of polyether sulfone fiber filaments subjected to surface treatment; the rope core is arranged in the rope cover and structured as an integrated body of the polyether sulfone fiber filaments. The polyether sulfone fiber compound rope is compact in knitting, reasonable in process, outstanding in heat resistance, physical and mechanical performances and insulation performance, and suitable for being applied to the site with high humidity and high temperature.

Description

technical field [0001] The invention belongs to the technical field of ropes, in particular to a polyethersulfone fiber core-spun rope and a preparation method thereof. Background technique [0002] The core-spun rope is widely used due to its good properties of the inner and outer materials. Therefore, the core-spun rope is an important daily necessities. In the existing core-spun rope, although it has other high performance, However, the heat resistance, physical and mechanical properties, and insulation properties are not high, and it is not suitable for high humidity and high temperature environments. Contents of the invention [0003] The object of the present invention is to provide a polyethersulfone fiber cored rope with excellent heat resistance and insulation performance and a preparation method thereof. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a polyethersulfone fiber core-spun rope, which includ...
