Abstract
Description
本発明は天然素材を用いた撚りロープ、撚り紐、縄（以下撚りロープと総称する）に関し、樹木等の雪吊りや添え木の結び等の農林業の分野、あるいは漁網等の水産業の分野等に適用するのに好適である。 The present invention relates to a twisted rope, a twisted string, and a rope (hereinafter collectively referred to as a twisted rope) using natural materials, such as the field of agriculture and forestry such as snow hanging of trees and knotting, or the field of fishery such as fishing nets. It is suitable to apply to.
現在例えば、底曳き網等にはポリエチレン糸、刺網や定置網等にはポリアミド糸等、それぞれの漁法に応じて各種合成繊維糸が使用されている。
富山湾等では、古くから定置網による漁法が行われ、漁網の網糸として古くから稲わらからなるわら縄が使用されてきたが、多くの定置網では耐久性に優れた合成繊維糸に置き換えられている。
しかし、合成繊維糸からなる漁網は耐久性に優れるものの、使用後の廃材処理が大変であり、近年においては環境への負荷も大きな問題になっている。
特に富山湾で、ホタルイカ漁に用いられる定置網は、ホタルイカの漁獲時期が４〜６月と短期間に限られていることもあり、現在も稲わらからなるわら縄を網糸に用いられている。
これは、わら縄が天然素材であり、ホタルイカの漁獲に使用後にそのまま、海に沈めることができるからである。
わら縄は、海中で菌により分解され、栄養源ともなる。
しかし、近年稲作の機械化が進展し、はさ掛け等による天日干しも殆ど消滅したために稲わらを確保するのが困難になりつつある。
そこで本発明者らは、わら縄に替わるロープ材を検討した結果、本発明に至った。
At present, various synthetic fiber yarns are used according to each fishing method, for example, polyethylene yarns for bottom nets and polyamide yarns for stabbed nets and stationary nets.
In Toyama Bay, etc., fishing methods using stationary nets have been used for a long time, and straw ropes made of rice straw have long been used as fishing nets. Yes.
However, although fishing nets made of synthetic fiber yarns are excellent in durability, disposal of waste materials after use is difficult, and in recent years, the burden on the environment has become a major problem.
Especially in Toyama Bay, stationary nets used for firefly squid fishing are limited to a short period of April-June, and the straw rope made of rice straw is still used for the net yarn. .
This is because straw rope is a natural material and can be submerged in the sea as it is after being used for catching firefly squid.
Straw rope is decomposed by fungi in the sea and becomes a nutrient source.
However, in recent years, the mechanization of rice cultivation has progressed, and the sun-drying due to the hook has almost disappeared, so it is becoming difficult to secure rice straw.
Then, the present inventors came to this invention as a result of examining the rope material replaced with a straw rope.
例えば特許文献１には、紙製の園芸用ロープを開示するが、これは樹木を移植先に根付かせるのが目的であり、強度も弱く、わら縄の代替になるものではない。 For example, Patent Document 1 discloses a paper gardening rope, which is intended to root a tree at a transplant destination, has low strength, and is not a substitute for a straw rope.
本発明は、従来のわら縄の代替品として使用可能であり、さらにはわら縄以上に柔軟性及び耐久性に優れた撚りロープの提供を目的とする。 An object of the present invention is to provide a twisted rope that can be used as a substitute for a conventional straw rope and is more flexible and durable than a straw rope.
本発明に係る撚りロープは、天然繊維からなる芯糸に、帯状の表層紙を一部が重なるように順次ずらしながら巻き付けた子紐を、複数本撚り合せたことを特徴とする。
ここで、前記芯糸と表層紙との中に、表層紙よりも軟質の帯状の中間紙を一部が重なるように順次ずらしながら巻き付けた子紐を用いてもよい。
The twisted rope according to the present invention is characterized by twisting a plurality of cords wound around a core yarn made of natural fibers while sequentially shifting a belt-shaped surface layer paper so as to partially overlap.
Here, a cord that is wound around the core yarn and the surface layer paper while being sequentially shifted so as to partially overlap a belt-shaped intermediate paper that is softer than the surface layer paper may be used.
芯糸は、天然素材であれば麻糸、綿糸、絹糸等各種材質を用いることができるが、強度及び入手のしやすさからすれば麻糸がよい。
麻糸は、繊維を単に束ねたものでも撚糸にしたものでもよく、ロープの太さ、強度に応じて本数を増す。
本発明において、中間紙は撚りロープの取扱い時のソフト感と結び等における柔軟性が必要な場合に巻き付けるものであり、比較的細い撚りロープの場合には中間紙がなくてもよい。
中間紙は、このような目的で用いるものであり、古新聞等古紙を再生したパルプ素材でよく、ソフト感の高い軟質のものでよい。
また、強度的にも表層紙よりも弱いものでよい。
表層紙はパルプ等の天然素材を用いたものであれば、耐水処理、撥水処理したものがよい。
ホタルイカ漁の漁網等として使用する場合には、３〜４ヶ月の使用期間であり、使用後には海中に沈めることを考慮し、表層紙の強度設計を行う。
なお、表層紙はパルプを主に使用したものであれば、古紙とバージンパルプを混合したものでもよく、耐水剤、撥水剤の添加のみでは、耐久性が不充分の場合には表面に樹脂フィルムを積層したものを用いても良い。
As the core yarn, various materials such as hemp yarn, cotton yarn, and silk yarn can be used as long as they are natural materials, but hemp yarn is preferable from the viewpoint of strength and availability.
The hemp yarn may be simply a bundle of fibers or a twisted yarn, and the number increases according to the thickness and strength of the rope.
In the present invention, the intermediate paper is wound when a soft feeling at the time of handling of the twisted rope and flexibility such as tying are required, and in the case of a relatively thin twisted rope, the intermediate paper may be omitted.
The intermediate paper is used for such a purpose, and may be a pulp material obtained by recycling old paper such as an old newspaper, and may be soft and soft.
Further, the strength may be weaker than the surface layer paper.
If the surface paper is made of a natural material such as pulp, it should be water-resistant and water-repellent.
When used as a fishing net for firefly squid fishing, etc., it is used for 3 to 4 months, and the strength of the surface paper is designed in consideration of being submerged in the sea after use.
In addition, as long as the surface paper is mainly made of pulp, it may be a mixture of waste paper and virgin pulp. You may use what laminated | stacked the film.
本発明は、麻糸等の天然素材からなる芯糸にパルプを原料にした紙からなる中間紙及び表層紙を巻き付けたものを子紐とした撚りロープにしたので、強度と柔軟性を兼ね備えることができ、従来のわら縄の代替品として使用できるのみならず、わら縄以上の強度、耐久性、及び結び等の取扱性に優れる。
よって、林業における樹木の雪吊り、結び、漁業における定置漁等多くの分野にて使用できる。
Since the present invention is a twisted rope that uses a core thread made of a natural material such as hemp yarn and a paper made of pulp as a raw material and a surface layer paper wrapped around the core, it has both strength and flexibility. In addition to being able to be used as a substitute for a conventional straw rope, it is superior in strength, durability, and handling properties such as knots.
Therefore, it can be used in many fields such as snow hanging and tying of trees in forestry and stationary fishing in fishery.
本発明に係る撚りロープは、わら縄の代替、撚り紐、網糸等と各種ロープ材として使用できる。
図１に基本的な構造例を示す。
撚りロープ１０は麻糸１１を複数本束ね芯糸とする。
本実施例では、麻糸１１を２本にした例で麻糸１１を９本にした例を図３に示す。
麻糸１１からなる芯糸の周囲に古新聞紙から得られた軟質の再生紙を中間紙として、帯状にしたものを一部重ねながら、渦巻状に巻き付ける。
その上から、表層紙１３を中間紙１２と同じ方向に巻き付ける。
このようにして得られた子紐１４を複数本、本実施例では２本の子紐を子紐の巻き方向とは逆方向に撚り合せて撚りロープ１０を製作した。
このときのＡ−Ａ線断面図を図２に示す。
本実施例に用いた表層紙は、古紙とバージンのパルプを使用し、紙厚７０〜１００μｍ、引張り強度縦方向６ｋｇｆ以上、横方向１ｋｇｆ以上、引裂き強度縦方向３５ｋｇｆ以上、横方向７０ｋｇｆ以上、伸度４％以下のものを用いた。
これを網糸としてホタルイカの漁網を網み、海中で使用したところ、従来のわら縄以上の耐久性があった。
The twisted rope according to the present invention can be used as various rope materials such as a straw rope substitute, a twisted string, a mesh thread and the like.
