Embodiment 1

[0076] The lightweight wear-resistant multifunctional composite power single rope disclosed in Example 1 is made by the following method:

[0077] (1) The composite rope core is made of polyamide fiber and high-strength low-elongation fiber, including:

[0078] (1-1) Select 8 polyamide fibers with a specification of 840D, and first twist to obtain the first rope core first twist strand, and the initial twist twist is set to 200 twists / meter; Retwisting, obtaining the first rope core retwisting strand, the retwisting direction is opposite to the initial twisting direction, and the retwisting twist is set to 160 twists / meter;

[0079] (1-2) Select 8 high-strength and low-elongation fibers with a specification of 840D, and first twist to obtain the first-twisted strands of the second rope core; the initial twist twist is set to 200 twists / meter; The strands are retwisted to obtain the second rope core retwisted strands, the retwisting direction is opposite to the initial twistin...

Embodiment 2

[0088] The lightweight wear-resistant multifunctional composite power single rope disclosed in Example 2 is made by the following method:

[0089] (1) The composite rope core is made of polyamide fiber and high-strength low-elongation fiber, including:

[0090] (1-1) Take 8 polyamide fibers whose specification is 1260D, and the initial twist is the first rope core strand, and the initial twist twist is set to 150 twists / meter;

[0091] (1-2) Take 8 high-strength and low-elongation fibers with a specification of 1260D, and the initial twist is the second core rope strand, and the initial twist twist is set to 150 twists / meter;

[0092] (1-3) pre-weaving the first core rope strand and the second core rope strand respectively on the pre-loom to obtain strands corresponding to the capacity of the bobbins;

[0093] (1-4) Putting the pre-woven bobbin on a braiding machine for braiding to obtain a braided composite rope core.

[0094] (2) The composite rope core is heat-set, the he...

Abstract

The embodiment of the present application discloses a light-weight and wear-resistant multifunctional composite power single rope. The rope core fiber is composited, and the rope sheath is composed of the first rope sheath and the second rope sheath arranged at intervals along the axial direction of the power single rope, wherein: the first rope core fiber is polyamide fiber, and the second rope core fiber is high Low-strength extension fiber, the first rope core fiber and the second rope core fiber are parallel-strand composited or braided to obtain a composite rope core; the rope sheath is woven from composite fiber strands, and the pitch is 25-30mm to form the second rope. The first rope sheath is braided at a pitch of 32-40mm to form the second rope sheath; the composite fiber strands are composed of polyamide fibers with a ratio of 4:1 and high-strength and low-elongation fibers; high-strength and low-elongation fibers include super One or a combination of high molecular weight polyethylene fibers, Vectran fibers, aramid fibers, carbon fibers, and glass fibers.

Description

technical field [0001] The application belongs to the technical field of special ropes, and in particular relates to a lightweight and wear-resistant multifunctional composite power single rope and a manufacturing method thereof. Background technique [0002] Power rope climbing rope is divided into single rope, half rope and double rope. A single rope is a power climbing rope that can be used alone. It is used alone and is stressed separately to prevent climbers from falling. It is the most common type of rope. In use, a rope is hung into a protection point. When the climbing route is not very tortuous , mostly use this kind of rope. The single rope is not suitable for multi-stage descent, and is mostly used for sports climbing. It can be tightened when the rock climber falls. Because of its high extensibility, it can reduce the impact force of the falling person and improve the cushioning performance, thereby ensuring their personal safety. [0003] Static A-type rope ca...
