The micro-elastic double-braided rope comprises a rope skin layer and a rope core layer which are sleeved, wherein the rope core layer is formed by surrounding a central twisted wire by a plurality of braided twisted wires. The braided twisted wires of the rope core layer formed by the micro-elastic double-braided rope designed by the utility model are of multi-strand twisted wire structure, so that the rope skin and the rope core are more attached, the sliding of the rope core layer relative to the rope skin can be effectively reduced during application, and the elongation of the rope is increased.
Description
Technical Field
The utility model relates to the technical field of ropes, in particular to a micro-elastic double-braided rope.
Background
The micro-elastic double-braided rope has very wide application in social life, the double-braided rope is a rope with a rope skin and a rope core both adopting braided structures, the rope core of the traditional double-braided rope is formed by braiding single stranded twisted wires, the gap between the rope skin and the rope core of the micro-elastic double-braided rope braided by the mode is large, the attaching degree is poor, and the rope is easy to form a hollow and is not round enough. The relative sliding of the rope skin and the rope core of the rope is large in the application process, the braided wires of the rope are easy to wear and break, the elongation is low, and the slow elasticity is poor.
Disclosure of Invention
In order to solve the problems in the prior art, the utility model designs a micro-elastic double-braided rope to solve the problems of large relative sliding and easy abrasion between the rope skin and the rope core of the existing double-braided rope.
The technical scheme adopted by the utility model is as follows: the micro-elastic double-braided rope comprises a rope skin layer and a rope core layer which are sleeved, wherein the rope core layer is formed by surrounding a central strand by a plurality of braided twisted wires.
Further, the braided twisted wires of the rope core layer are braided by three strands of twisted wires.
Further, the central strand of the rope core layer is a single strand twisted wire or a 3 strand twisted wire.
Further, the structure of the braided twisted wire of the rope core layer is 12 or 16 braiding.
Further, the rope cortex is a sheath structure formed by braiding a plurality of strands of twisted wires, the braiding structure of the rope cortex is 16 braiding, 24 braiding or 32 braiding, and the number of the S-twist and the Z-twist twisted wires in the plurality of strands of twisted wires for braiding is half.
Compared with the prior art, the micro-elastic double-braided rope designed by the utility model has the advantages that: the rope core layer of the double-braided rope adopts a three-strand twisted yarn braiding structure, so that the rope core layer is more abundant, the gap between the rope skin and the rope core is reduced, and the rope skin and the rope core are more attached, thereby reducing the relative sliding of the rope skin and the rope core of the rope in the application process and reducing the abrasion; meanwhile, a single stranded twisted wire or three stranded twisted wires are added to the center of the rope core formed by braiding, so that the rope core layer formed by braiding is more round and smooth, and the whole hand feeling of the formed rope is more full; in addition, the central strand of the rope core layer adopts three strands of twisted yarns to have higher elongation than single strands of twisted yarns, so that the micro-buffering elasticity of the rope can be further improved.

The rope core layer 2 is formed by surrounding a central strand 3 by three strands of braided twisted yarns 4, the braiding structure of the braided twisted yarns 4 can be selected from 12 braiding or 16 braiding, and the central strand 3 adopts 3 strands of twisted yarns.
The utility model discloses a manufacturing method of a micro-elastic double-braided rope, which comprises the following steps:
step one: rope skin twisting: selecting 4 nylon fibers, and setting the twist degree to 80 twists/m through a twisting machine to obtain S-twisted and Z-twisted rope cortex strands;
step two: rope skin twisting pre-weaving: pre-weaving the rope cortex strand wires in the first step onto a 140-32 yarn cop tube through a full-automatic doubling machine;
step three: manufacturing rope core strand wires: 6 nylon fibers are selected to form single-stranded twisted yarns through primary twisting, three identical single-stranded twisted yarns are selected to obtain three-stranded braided twisted yarns through secondary twisting, the primary twisting is set to 120 twists/meter, and the secondary twisting is set to 80 twists/meter;
step four: pre-weaving the three-strand woven twisted yarns in the third step onto a 168-16 yarn-weaving tube through a full-automatic doubling machine;
step five: braided rope core layer: placing the yarn tube pre-woven in the fourth step on a weaving machine, arranging three single twisted yarns prepared in the third step in the middle of the yarn tube as a central line strand, and weaving to form a rope core layer;
step six: braiding into ropes: and (3) placing the yarn tube pre-woven in the step two on a weaving machine, adding a rope core layer in the middle, and weaving the rope skin layer strand around the rope core layer to form a double-woven rope.
The foregoing is merely illustrative of the present utility model and is not intended to limit the scope of the utility model, i.e., all such modifications and variations are within the scope of the utility model as defined in the appended claims and their equivalents.
