Description

本考案は2種類以上の糸素材からなる複合糸に関するもので、更に詳しくは、熱可塑性エラストマーからなる芯糸に、他の被覆糸をカバリングした高強力伸縮性極太カバードヤーンに関するものである。   The present invention relates to a composite yarn composed of two or more types of yarn materials, and more specifically to a high-strength stretchable extra-thick covered yarn in which a core yarn made of a thermoplastic elastomer is covered with another coated yarn.

従来のカバードヤーンは、単糸繊度が3デニール程度、総繊度が10〜40デニール程度の、ウレタン結合を有する熱可塑性ポリウレタンや、エステル結合、エーテル結合を有する熱可塑性エラストマー等の弾性繊維を芯糸とし、5〜30デニールのナイロンやポリエステルフィラメント等の合成繊維を巻回糸としたシングルカバードヤーンやダブルカバードヤーンがあり、これらはソックス、ストッキング、タイツ、肌着、伸縮性を有するパンツなどの衣料に使用されている。これらのカバードヤーンに関しては、例えば、下記特許文献1〜4に開示されている。   Conventional covered yarns are made of elastic fibers such as thermoplastic polyurethanes having urethane bonds and thermoplastic elastomers having ester bonds and ether bonds having a single yarn fineness of about 3 denier and a total fineness of about 10 to 40 deniers. There are single-covered yarn and double-covered yarn with 5-30 denier nylon or polyester filament wound as synthetic yarn, and these are suitable for clothing such as socks, stockings, tights, underwear, elastic pants, etc. in use. These covered yarns are disclosed in, for example, the following Patent Documents 1 to 4.

従来のカバードヤーンは衣料用途であるため、一般的に細いヤーンが普通である。また編み立てや製織工程を通すためにも細いヤーンでなければならず、通常15〜30デニール程度で、太くても100デニール程度である。衣料用途以外のカバードヤーンに関しては、例えば、下記特許文献5〜6に開示されている。これらのカバードヤーンも衣料用途と同様に、単糸3デニール程度のポリウレタン等の弾性繊維を芯糸とし、ナイロンやポリエステルフィラメント等の合成繊維を巻回糸としたシングルカバードヤーンやダブルカバードヤーンであって、太いものでも500デニール程度である。   Since conventional covered yarns are used for clothing, thin yarns are generally common. In order to pass through the knitting and weaving process, the yarn must be thin, usually about 15 to 30 denier and even about 100 denier. Covered yarns other than those used for clothing are disclosed in, for example, Patent Documents 5 to 6 below. Like covered clothing, these covered yarns are single covered yarns and double covered yarns using elastic fibers such as polyurethane with a single yarn of about 3 denier as the core yarn and synthetic fibers such as nylon and polyester filaments as wound yarns. Even a thick one is about 500 denier.

従来公知のカバードヤーンは、ヤーン一本の引張り破断強力は高くても3000gf未満で、3000gf以上の大きな引張り破断強力が要求される産業資材分野の用途に展開することは困難とされていた。本考案は上記の様な事情に着目してなされたものであって、本考案は産業資材分野の用途に展開が可能であり、伸縮性を有し、且つ、ヤーン一本の引張り破断強力が3000gf以上の大きな破断強力を有し且つ従来に見ない高強力で伸縮性を有する極太の新規なカバードヤーンを提供することにある。   A conventionally known covered yarn has a tensile strength of less than 3000 gf even if the single yarn has a high tensile breaking strength, and it has been difficult to develop it in an industrial material field where a large tensile breaking strength of 3000 gf or more is required. The present invention has been made by paying attention to the circumstances as described above. The present invention can be applied to industrial materials, has elasticity, and has a tensile breaking strength of a single yarn. An object of the present invention is to provide a novel thick covered yarn having a large breaking strength of 3000 gf or more and a high strength and stretchability not seen in the past.

本考案者らは、前記課題を解決するために鋭意研究を重ねた結果、ヤーン一本の引張り破断強力が3000gf以上であり、且つ、従来に見ない極太の新規なカバードヤーンを見出し、本考案を完成するに至った。すなわち本考案のカバードヤーンは、芯糸に他の被覆糸として紡績糸あるいはフィラメント糸を巻き回した複合糸であり、前記芯糸として、直径0.15〜1.5mmの熱可塑性エラストマー線材を用いたことを特徴とする高強力伸縮性極太カバードヤーンである。   As a result of intensive studies to solve the above-mentioned problems, the inventors have found a novel covered yarn that has a tensile breaking strength of 3000 gf or more and that is not seen in the past. It came to complete. That is, the covered yarn of the present invention is a composite yarn in which a spun yarn or a filament yarn is wound as another coating yarn around a core yarn, and a thermoplastic elastomer wire having a diameter of 0.15 to 1.5 mm is used as the core yarn. It is a high-strength stretchable extra-thick covered yarn.

カバードヤーン1m当りの巻回糸の巻回数が200〜900回であることが好ましい。   The number of winding yarns per 1 m of covered yarn is preferably 200 to 900.

本考案は従来に見ない極太カバードヤーンであり、その伸縮特性と高強力を活かし、織編物に加工した場合は、車のシートベルト、荷物固定ベルト、荷物を繋ぐベルト、ゴムベルトの芯材等に好適であり、紐に加工した場合は、荷物固定紐、動物のリード、落下傘の紐、漁業用の延縄等に好適である。熱可塑性エラストマーからなる線材としてはゴムとプラスチックの両方の特性を有するポリエステルエラストマーからなる線材が好適であり、例えば具体的には、東洋紡績株式会社のダイヤフローラ(登録商標)が好適である。   The present invention is an unprecedented ultra-thick covered yarn, and when it is processed into a woven or knitted fabric by taking advantage of its stretch characteristics and high strength, it can be used as a car seat belt, baggage fixing belt, baggage belt, rubber belt core, etc. When processed into a string, it is suitable for a luggage fixing string, an animal lead, a parachute string, a fishing line, etc. As the wire made of a thermoplastic elastomer, a wire made of a polyester elastomer having both rubber and plastic properties is suitable. For example, Diaflora (registered trademark) manufactured by Toyobo Co., Ltd. is suitable.

ダイヤフローラ(登録商標)は直径0.15mm以上の丸断面中実のモノフィラメントもしくはマルチフィラメントで、優れた伸長回復性を有すると共に、ポリエステル系であるため、含水することなくリサイクル性にも優れた特徴を有している。また、ダイヤフローラ(登録商標)を30%引張った後に応力を解放すると、完全に元の長さに戻り、永久歪が非常に小さいといった特徴を有している。この特徴から伸度30%以下での引張りと応力解放を繰り返した場合でも、繰り返し使用可能であるメリットがあり、伸縮性が必要なカバードヤーンの芯糸として非常に適している。また、原液着色された線材も芯材として好適である。
本考案のカバードヤーンの形態としては、シングルカバードヤーン、ダブルカバードヤーンのいずれも採用できる。
Diaflora (Registered Trademark) is a solid monofilament or multifilament with a diameter of 0.15 mm or more, and has excellent stretch recovery and is polyester, so it has excellent recyclability without moisture. have. Further, when the stress is released after the Diaflora (registered trademark) is pulled 30%, the original length is completely restored and the permanent set has a very small characteristic. Because of this feature, there is an advantage that it can be used repeatedly even when tension and stress release at an elongation of 30% or less are repeated, and it is very suitable as a core yarn of a covered yarn that requires stretchability. Further, a wire colored with a stock solution is also suitable as a core material.
As a form of the covered yarn of the present invention, either a single covered yarn or a double covered yarn can be adopted.

(結果の考察)
実施例1及び2は、カバードヤーンの巻回数が200回/m未満であり、引張り曲線の破断強力のピークが芯糸と巻回糸の二山に分かれ、一つのヤーンとしての応力曲線が得られなかった。また、実施例6は、巻回数が1200回/mのカバードヤーンであり、引張り曲線は二山に分かれず一つのヤーンとしての応力曲線が得られたが、ダイヤフローラモノフィラメント単独の応力曲線とほぼ同じで、目的とする高強力のヤーンが得られなかった。従って、目的とする高強力伸縮性のあるカバードヤーンの巻回数はシングルカバリングの場合、200から900回/mの範囲にあることが好ましいことが判明した。
(Consideration of results)
In Examples 1 and 2, the number of windings of the covered yarn is less than 200 times / m, the peak of the breaking strength of the tensile curve is divided into two threads, the core yarn and the winding yarn, and a stress curve as one yarn is obtained. I couldn't. Further, Example 6 is a covered yarn having a winding number of 1200 times / m, and the tensile curve was not divided into two peaks, and a stress curve as one yarn was obtained. The same high-power yarn was not obtained. Therefore, it has been found that the number of turns of the target covered yarn having high strength and elasticity is preferably in the range of 200 to 900 turns / m in the case of single covering.
