Definitions
- the present invention relates to a synthetic fiber rope, in particular, a synthetic fiber rope formed by twisting or combining a plurality of strands.
- a conventional synthetic fiber rope is generally a yarn assembly in which a plurality of yarns are produced through a twisting process once or twice, and twisted while aligning a plurality of yarns. And a plurality of the strands are twisted or combined. Generally, three ropes made by twisting three strands are hit, and eight ropes combining eight strands are called eight hits, and there are ropes that combine even numbers of strands such as 12, 16, and so on. (See Patent Documents 1 and 2) Moreover, as the above-mentioned strand, there is a strand in which a large number of synthetic fibers are used as a core material and are bundled by a cylindrical outer layer formed in a braid shape, and there is a rope obtained by twisting these strands. (See Patent Document 3)
- the present invention has been made in order to solve the above-mentioned problems.
- the object of the present invention is to provide a cylindrical woven fabric composed of warps and wefts of synthetic fibers, and synthetic fibers converged in the cylindrical woven fabric.
- An object of the present invention is to provide a synthetic fiber rope comprising a bundle of core materials and a plurality of strands formed by twisting or combining the strands.
- the synthetic fiber rope of the present invention is composed of a woven fabric composed of warps and wefts of synthetic fibers as a strand and these are twisted or combined, the following effects are obtained. 1) Since the warp and core material of the cylindrical woven fabric are oriented in the longitudinal direction of the rope, it is possible to provide a rope with high tensile strength and a small elongation rate. And the elongation rate substantially the same as that of the synthetic fiber used can be ensured. 2) Since the core material is restrained by the tubular woven fabric, the shape of the rope can be easily kept stable, and the rope lead (one twist of the strand) can be freely set. 3) Suitable for manufacturing ropes with a large nominal thickness (diameter).
- reference numeral 1 denotes a synthetic fiber rope, which is formed by twisting a plurality of strands 2 (12 in this embodiment). In this twisting, it is preferable not to twist each strand 2 in order to reduce the elongation, but in the present invention, twisting is not excluded. In order to prevent twisting of the strands, different lines of color may be inserted into a part of the warp yarn of the cylindrical fabric of each strand.
- the number of strands of the strand 2 is not limited to 12 in the present embodiment, but is appropriately determined according to the use in the marine product field, the ship field, the land field, and the type and thickness of the synthetic fiber to be used. To do. Moreover, you may put the center material which consists of a synthetic fiber, a metal wire, etc. in the center part of the synthetic fiber rope 1.
- FIG. 1 denotes a synthetic fiber rope, which is formed by twisting a plurality of strands 2 (12 in this embodiment). In this twisting, it is preferable not to twist each strand
- the strand 2 is composed of a cylindrical fabric 3 made of synthetic fiber warps and wefts, and a core 4 made of a synthetic fiber bundle focused in the cylindrical fabric 3. Composed.
- the synthetic fibers include polyamide fibers such as nylon, polyester fibers, polyacrylonitrile fibers, polyvinyl alcohol fibers such as vinylon, polypropylene fibers, polyvinyl chloride fibers, polyethylene fibers, and polyvinylidene chloride fibers.
- Fibers and polyurethane fibers can be mentioned, but from the viewpoint of strength and elongation that can withstand high tensile forces, polyester fibers, ultrahigh molecular weight polyethylene, aramid fibers, polyarylate fibers, carbon fibers, metal wires, etc. However, a synthetic fiber having a low elongation is preferred. Moreover, what is necessary is just to select suitably the woven structure which can be woven into a cylindrical shape, such as a plain weave and a twill weave, for example.
- FIG. 3 shows another embodiment in which the loop R is formed at the end of the rope by the satin processing S, and the strand of the present invention having a woven fabric structure of warp and weft is less likely to stretch than a strand having a conventional braid structure. Therefore, it is difficult to slip and a strong loop R can be formed.
- FIG. 4 shows another embodiment of a synthetic fiber rope provided with a coating 5.
- a synthetic resin thin film As the coating 5, a synthetic resin thin film, a plurality of synthetic fiber yarns knitted into a braided structure, or the above-mentioned tube Any of the same woven structures as the woven fabric may be used.
- Table 2 shows examples of existing technologies with respect to the above specific examples of the present invention.
- the synthetic fiber rope of the new technology has a same nominal thickness (diameter) of 36 mm, the same number of strands of 8 and a strong utilization factor of 2 compared to the conventional technology. .12 times (69.4% / 32.7%), and the tensile strength was proved to be excellent at 1.84 times. Further, it has been found that the synthetic fiber rope of the new technology (the present invention) can achieve a weight reduction of about 8% at the same nominal thickness (diameter) as compared with the conventional technology.
- the strand of the present invention has a good shape retaining property because it is composed of a cylindrical fabric composed of warps and wefts of synthetic fibers, and a core material composed of a bundle of synthetic fibers focused in the tubular fabric. . Therefore, even if the lead is lengthened, the utility is not lost.
- Table 4 shows test data such as changes in rope breaking strength and strength utilization ratio due to differences in rope leads.
- the rope leads are 3.00, 3.78, 4.58, 5.64 and 6.64.
- the breaking strength (kN) is 236, 305, 352, 376 and 366, respectively
- the strength utilization (%) is 46.3, 59.8, 69.0, 73.7 and 71, respectively. .8.
- the rope lead when the rope lead is stretched as in the present invention, the shape of the strand is not maintained, and there are cases where there is a problem in practical use, such as a decrease in wear resistance.
- the rope lead is determined to be 3.5 times or less in the JIS standard.
- the core material is concentrated in the tubular woven fabric, the shape of the strand can be maintained, and the rope lead can be extended more than 3.5 times.
- Table 4 if the rope lead is optimized, a high strength utilization rate of 73.7% can be obtained.
- the structure of the tubular woven fabric 3 composed of warp and weft may be any of conventionally known structures such as plain weave and twill weave.
- twill weave has less warp restraint, high tensile strength, and flexible strands.
- the tubular woven fabric 3 may be woven with any of a shuttle loom, a needle loom, or a circular loom.
- the plain looms such as the shuttle loom and needle loom interweave the plain fabric through the weft with the shuttle or needle between the warp yarns that alternately open and close, and sew both ends of the plain fabric with different yarns, or the weft yarn of the needle To form a cylinder.
- a circular loom is a circular loom, which is a loom in which warp yarns are supplied radially from the outer periphery of the loom, and the weft yarn is woven while rotating in the circumferential direction.
- the tubular fabric woven with the loom does not have a binding ear, not only the strength of the tubular fabric in the circumferential direction can be increased, but also there are the following advantages. That is, (1) since there are no binding ears (unevenness), the structure of the cylindrical fabric becomes uniform and wear resistance is improved. (2) Since there are no binding ears, bending in all directions becomes flexible and there is no bending habit. (3) Since there are no binding ears, the elongation in the length direction of the strands is uniform and the strength is improved.
- the strand 2 having a small twist is identified by weaving a sense line in which a part of the warp of the tubular woven fabric 3 has a color different from that of the other warp.
- a sense line in which a part of the warp of the tubular woven fabric 3 has a color different from that of the other warp.
- the synthetic fiber rope of the present invention has a high tension and has an elongation rate almost equal to that of the synthetic fiber, and is used as an alternative rope in the marine, marine or land fields where conventional wire ropes have been used. There is a possibility of use.

Abstract
Description
また、上記ストランドとして、多数の合成繊維を芯材として、これを組紐状に構成した筒状の外層により集束したものがあり、これらのストランドを撚り合わせたロープもある。(特許文献3参照)
1)筒状織物の経糸および芯材が、ロープの長手方向に配向されているので、高張力で伸び率の小さいロープを提供することができ、合成繊維の引張り強さの強力利用率を飛躍的に向上させることができると共に、使用される合成繊維の伸び率とほぼ同一の伸び率を確保することができる。
2)筒状織物で芯材を拘束するため、ロープの形状を安定的に保ち易く、ロープリード(ストランドの1回の撚り程)を自由に設定することができる。
3)称呼太さ(直径)の大きいロープの製造に適している。
図1において、1は合成繊維ロープであって、複数本(本実施例では12本)のストランド2を撚り合わせて構成されている。この撚り合わせに際して、各ストランド2は捻らないことが、伸び率を小さくするために好ましいが、本発明において捻りを排除するものではない。ストランドの捻りがはいらないよう、各ストランドの筒状織物のタテ糸の一部に色の異なる識線を入れてもよい。上記ストランド2の撚り合わせ本数は、本実施例の12本に限定するものではなく、水産分野、船舶分野、陸上分野等の用途や、使用する合成繊維の種類や太さ等に応じて適宜決定する。また、合成繊維ロープ1の中心部に合成繊維や金属線などから成る中心材を入れても良い。
次に、本発明の具体例について、表1を参照しながら説明する。
本発明の上記具体例に対して、既存技術例を表2に示す。
続いて、上記既存技術と本発明技術を比較して、本発明の利点について説明する。
表4は、ロープリードの違いによるロープの破断強力および強力利用率の変化等の試験データを示すもので、ロープリードが、3.00、3.78、4.58、5.64および6.39の場合、破断強力(kN)は、それぞれ236、305、352、376および366であり、強力利用率(%)は、それぞれ46.3、59.8、69.0、73.7および71.8であった。上記ロープリードと強力利用率(%)の関係をグラフにしたものが、図5のグラフであって、ロープリードが5.6倍程度で強力利用率(%)が極大となることが判った。通常のストランドを用いた場合では、強力利用率は30~40%くらいであるので、データの73.7%は、かなり高い強力利用率である。
一方、本発明では、筒状織物内に芯材を集束しているため、ストランドの形状を保持することができ、ロープリードを3.5倍超に伸ばすことができる。これにより、表4に示すように、ロープリードを最適化すれば、73.7%と高い強力利用率を得ることができる。
