Abstract

The utility model provides a rope with a three-layer skin-core structure, which comprises an inner core, an inner surface skin and an outer surface skin from inside to outside in sequence; the inner skin is directly woven and formed on the surface of the inner core. The utility model comprises an inner skin and an outer skin, which are respectively wrapped on the inner core and the inner skin, so as to wrap the inner core into a whole and protect the inner core and the inner skin at the same time, thereby avoiding friction damage; the outer skin is in a plain weave structure, so that the fiber length of the inner core rope can be ensured to be consistent, the fracture non-uniformity is avoided, and the service life of the whole body is obviously prolonged; the leather core can be effectively prevented from slipping during movement, and the use safety is improved; make rope length want longer than ordinary rope, improve antifriction performance and cut resistance, the practicality is stronger.

Description

Rope with three-layer skin-core structure

Technical Field

The utility model belongs to weave the rope field, concretely relates to three-layer skin core structure rope.

Background

The rope of current skin-core structure comprises core rope and overcoat two-layer more, and the core rope is twisted into a thigh back by many parallel long filaments or spun yarn usually, weaves into various types of ropes with each strand yarn again and constitutes, and the overcoat is woven by the yarn that the sub-thigh constitutes more and is formed, protects inside core rope through the overcoat, prevents its wearing and tearing destruction, plays certain pleasing to the eye effect simultaneously, improves the intensity of rope through the core rope in the overcoat. According to the rope with the sheath-core structure, when the core rope is of a parallel structure, the advancing speed of parallel filaments or yarns in the core rope can be different during weaving, so that the lengths of the filaments or yarns in the woven core rope are different, when the rope is stressed, fibers in the core rope can lose effectiveness due to different fracture, and the service life of the rope is shortened; in addition, when the rope with the sheath-core structure is stressed, the outer sleeve and the core rope are easy to slip.

Therefore, it is an urgent need to solve the above problems by those skilled in the art to develop a safer sheath-core rope.

Disclosure of Invention

In order to solve the problem, the utility model discloses a three-layer skin core structure rope.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

a rope with a three-layer skin-core structure sequentially comprises an inner core, an inner surface skin and an outer surface skin from inside to outside; the inner skin is directly woven and formed on the surface of the inner core.

Furthermore, the inner core consists of a plurality of parallel inner core tows; the inner surface skin is formed by weaving a plurality of strands of inner surface skin yarns; the outer skin is formed by weaving a plurality of strands of outer skin yarns.

Further, the inner core tow consists of two sub-strands.

Further, the inner skin yarn is composed of two interwoven inner skin system yarns.

Further, the feeding angles of the two strands of the inner skin system yarns are 45 ° and 135 °, respectively, and each strand of the inner skin system yarn is composed of two sub-strands.

Furthermore, the outer skin yarn is formed by interweaving two strands of outer skin system yarns in a warp-weft mode; the outer skin is of a plain structure.

Further, the warp of the outer skin system yarn consists of two spun yarns; the spun yarn is composed of three strands of sub-yarns; the weft of the outer sheath system yarn consists of three sub-yarns.

The invention has the beneficial effects that:

1. the inner core and the inner skin are wrapped into a whole, and the inner core and the inner skin are protected to avoid friction damage;

2. the outer skin is in a plain weave structure, so that the fiber length of the inner core rope can be ensured to be consistent, the fracture non-uniformity is avoided, and the service life of the whole body is obviously prolonged;

3. the leather core can be effectively prevented from slipping during movement, and the use safety is improved;

4. make rope length want longer than ordinary rope, improve antifriction performance and cut resistance, the practicality is stronger.

As shown in fig. 1-3, the utility model relates to a rope with a three-layer sheath-core structure, which comprises an inner core 1, an inner surface skin 2 and an outer surface skin 3 from inside to outside in sequence.

The inner core 1 consists of a plurality of parallel inner core tows, and the inner core tows consist of two sub-yarns.

The inner surface skin 2 is directly woven and formed on the surface of the inner core 1, and the inner surface skin 2 is woven and formed by a plurality of strands of inner surface skin yarns; the inner skin yarn is formed by interweaving two strands of inner skin system yarns; the feeding angles of the two strands of inner skin system yarns are 45 degrees and 135 degrees respectively, and each strand of inner skin system yarn is composed of two sub-yarns.

The outer skin 3 is an outer skin with a plain structure and is formed by weaving a plurality of strands of outer skin yarns, and the outer skin yarns are formed by interweaving two strands of outer skin system yarns; the warp of the outer skin system yarn consists of two spun yarns; the spun yarn is composed of three strands of sub-yarns; the weft of the outer sheath system yarn consists of three sub-yarns.

It should be noted that the above-mentioned contents only illustrate the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and it is obvious to those skilled in the art that several modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations fall within the protection scope of the claims of the present invention.
