Problems solved by technology

Among them, the parachute rope is a very important link. The parachute is related to the safety of the parachute, and even the life safety of the user. Therefore, the material for the parachute rope must have a compact structure, high strength, softness, good elasticity, and no elongation. The uniform rate is small, and the parachute and parachute ropes used at home and abroad are all made of ordinary chemical fibers, which has potential safety hazards to a certain extent.

preparation example Construction

[0018] The preparation method of this high-performance parachute parachute is realized through the following steps:

[0019] 1. Material selection: select multiple ultra-high molecular weight polyethylene fiber filaments with surface treatment specifications of 1000D-3000D;

[0020] 2. Paralleling: 6 ultra-high molecular weight polyethylene fibers are combined into one strand;

[0021] 3. Twisted yarn: The UHMWPE filaments after paralleling 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 rotational speed and twist are measured regularly , the twist depends on the size of the rope strands;

[0022] 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;

[0023] 5. Rope formation: Put the pre-woven bobbin on t...

Abstract

The invention discloses a high-performance parachute rope and a production method thereof and relates to the field of ropes. The high-performance parachute rope comprises a shell (1) and a rope core (2). The shell (1) is made by weaving half S-directionally-twisted and half Z-directionally-twisted ultra-high molecular weight polyethylene fiber strands. The rope core (2) is disposed inside the shell (1). The rope core (2) is a thermally-set combination of triple strands of high-strength high-elasticity nylon fiber. The high-performance parachute rope is compactly knitted, is high in strength modulus, fine in impact resistance, cutting resistance, bending performance, light resistance, abrasion resistance and chemical corrosion endurance, and is widely applicable to the field of aerospace as lifesaving parachutes, paratrooper's parachutes, drag parachutes, aerial bomb parachutes, cargo parachutes, recovery parachutes and the like.

Description

technical field [0001] The invention relates to the field of ropes, in particular to a high-performance parachute umbrella rope and a manufacturing method thereof. Background technique [0002] A parachute is an aviation tool that uses air resistance and relies on an expandable aerodynamic reducer that is inflated and deployed relative to air movement to safely land people or objects from the air to the ground. Mainly made of flexible fabric. It is the equipment and equipment for airborne combat and training, lifesaving and training for aerospace personnel, parachute jumpers for training, competitions and performances, airdrops, and recovery of aircraft. Among them, the parachute rope is a very important link. The parachute is related to the safety of the parachute, and even the life safety of the user. Therefore, the material for the parachute rope must have a compact structure, high strength, softness, good elasticity, and no elongation. The uniform rate is small, and th...
