（ａｌ 産業上の利用分野
本発明は、プラスチック製の模造イグサに関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to imitation rushes made of plastic.
偽） 従来の技術
イグサは、非常に古くから畳表、鑵等に用いられている
ものである。False) Conventional technology Rush has been used for tatami mats, tatami mats, etc. since ancient times.
このイグサの性質は、こしがあり、香がよく、通気性が
よい等非常に優れたものである。The properties of this rush are very good, such as being firm, fragrant, and breathable.
しかし、なから天然品であるがゆえの欠点、即ち、耐候
性が悪く、日光による変色や変質が避けられない、また
、天然品であるがゆえに、雑菌、だに等の害虫等の繁殖
という欠点を有している。However, because it is a natural product, it has disadvantages such as poor weather resistance, unavoidable discoloration and deterioration due to sunlight, and the fact that it is a natural product, so it is prone to the breeding of pests such as bacteria and mites. It has its drawbacks.
さらに、天然品であるため供給が安定せず、最近ではそ
の価格も高騰しているものである。Furthermore, since it is a natural product, its supply is unstable, and its price has been rising recently.
これら゛のために、近年プラスチックの筒状体をこのイ
グサの代用品にするという考案もなされ、花筺等には多
く用いられでいる。For these reasons, in recent years, the idea of using plastic cylindrical bodies as a substitute for rushes has been devised, and they are often used in flower baskets and the like.
（Ｃ） 発明が解決しようとする問題点しかし、プラ
スチックの筒状体では、その感触風合も悪く、畳という
感じはしない。よって、とても畳表や鐘等の代用にはな
らず、全く別のビニールシートのような製品になってし
まう。(C) Problems to be Solved by the Invention However, the plastic cylindrical body has a poor texture and does not feel like a tatami mat. Therefore, it cannot be used as a substitute for tatami mats, bells, etc., and becomes a completely different product like a vinyl sheet.
本業界では、供給が安定し、安価で、変質や変色がなく
、雑菌害虫の発生の少ないもので、需要者の嗜好に合っ
た風合、外観を有するイグサ様材料が要望されていた。In this industry, there has been a demand for a rush-like material that is stable in supply, inexpensive, free from deterioration or discoloration, less susceptible to germs and pests, and has a texture and appearance that suit the tastes of consumers.
＋ｄｌ 問題点を解決するための手段以上のような現

を通過させることによって、不規則に収束形成し、かつ
表面に融着皮膜を形成させた点にある。+dl Means to Solve the Problems In view of the current situation as described above, the present inventor has completed the imitation rush of the present invention as a result of intensive research, and its characteristics are as follows.
A string-like body made of a thermoplastic resin stretched in the longitudinal direction, the string-like body being irregularly converged by passing through a narrow gap through a cylindrical body having a large number of uneven wrinkles, and having a surface texture. The point is that a fusion film is formed on the surface.
ここで、熱可塑製樹脂とは、加熱することによって粘度
が低下し、成型が容易になる性質を有するプラスチック
をいい、ポリオレフィンがその代表的なものである０例
えば、ポリエチレン、ポリプロピレン等である。勿論、
これら以外の熱可塑性樹脂も使用できることはいうまで
もない、さらに、複数の樹脂を混合したものであっても
よい。Here, the thermoplastic resin refers to a plastic whose viscosity decreases when heated, making it easy to mold, and polyolefin is a typical example thereof. Examples thereof include polyethylene, polypropylene, etc. Of course,
It goes without saying that thermoplastic resins other than these may also be used, and a mixture of a plurality of resins may also be used.
さらに、この熱可塑性樹脂にポリカーボネートを混合す
ると、曲げ剛性が大きくなり、所謂こしの強いものとな
る。このことは、天然のイグサに近いものとなるばかり
か、織機等による取り扱いが非常に容易となり、従来の
天然イグサ用の機械も使用できることとなる。Furthermore, when polycarbonate is mixed with this thermoplastic resin, the bending rigidity increases, resulting in a so-called stiff material. This not only makes it similar to natural rushes, but it also becomes very easy to handle with a loom or the like, and conventional machines for natural rushes can also be used.
ポリカーボネートの混合比率としては、熱可塑性樹脂中
５％〜４０％がよく、好ましくは５％〜２０％程度であ
る。５％以下では、こしが弱く、４０％以上ではしなや
かさが低下するためである。The mixing ratio of polycarbonate in the thermoplastic resin is preferably 5% to 40%, preferably about 5% to 20%. This is because if it is less than 5%, the stiffness will be weak, and if it is more than 40%, the flexibility will be reduced.
熱可塑性樹脂には、これ以外に通常混合されるものを混
合しても問題はない０例えば、顔料、つや消し剤その他
のものである。特にイグサ特有の色を表現するために顔
料が必要である。There is no problem even if the thermoplastic resin is mixed with other materials that are normally mixed therein, such as pigments, matting agents, and the like. In particular, pigments are necessary to express the colors unique to rushes.
延伸は紐状体の長手方向に行い、通常２倍〜７倍程度で
よい。Stretching is performed in the longitudinal direction of the string-like body, and is usually about 2 times to 7 times.
筒状体とは、インフレーシラン加工によって製造された
もののような形状をいい、長いストロ−状のものを指す
。The cylindrical body refers to a long straw-shaped body manufactured by inflation silane processing.
凹凸皺とは、前記筒状体の長手方向に並行に存在する波
のような皺をいい、完全に規則的である必要はない、さ
らに、波状ではなく多数の肉厚筋部分を設けても同様で
ある。この皺によって、紐状体として所謂ボリューム感
が出、単なる筒状体のストロ−型と連なり、天然イグサ
の様子を呈するのである。The uneven wrinkles refer to wave-like wrinkles that exist parallel to the longitudinal direction of the cylindrical body, and they do not have to be completely regular. The same is true. These wrinkles give the string-like body a so-called voluminous feel, and it connects with the straw-shaped cylindrical body, giving it the appearance of natural rushes.
狭い空隙とは、筒状体の直径よりも狭いという意味であ
り、この空隙を通過させることによって大きな径の筒状
体を収束させて、イグサ程度の太さにするのである。空
隙を通過させるだけでは、保形性がないため、加熱し表
面を融着させる。これによって、イグサ程度の径を保つ
ことができ、さらに所謂こしの強さが生まれるのである
。A narrow gap means that the gap is narrower than the diameter of the cylindrical body, and by passing through this gap, the cylindrical body with a large diameter is converged and becomes as thick as a rush. Simply passing through the gaps does not provide shape retention, so heating is performed to fuse the surfaces. This allows it to maintain a diameter comparable to that of rushes, and also gives it the so-called stiffness.
製造方法の概略を第１図に基づいて説明する。An outline of the manufacturing method will be explained based on FIG. 1.
（１）上記説明した熱可塑性樹脂原料を準備する。(1) Prepare the thermoplastic resin raw material explained above.
偉） 原料をインフレーシラン装置（１）のフィーダー
（２）に導入する。1) Introduce the raw material into the feeder (2) of the inflation silane device (1).
（３） 金型（３）から押し出し、冷却装置（４）を
通して中空の状態で膨出させる。(3) It is extruded from the mold (3) and expanded in a hollow state through the cooling device (4).
この時の中空状態の径は、２００〜３００ｍｍ程度が好
適である。厚みは、０，０５〜０．０７＋ｗｍ程度であ
ル、コレヲロール（５）間に通過させて二重フィルムと
する。The diameter of the hollow state at this time is preferably about 200 to 300 mm. The thickness is approximately 0.05 to 0.07+wm, and the film is passed between core rolls (5) to form a double film.
この膨出の際に同時に凹凸皺が形成される。At the same time as this swelling, uneven wrinkles are formed.
これは金型に多数の溝又は突起を設けるだけで容易に製
造できるものである。This can be easily manufactured by simply providing a large number of grooves or protrusions in a mold.
（４）延伸する１、延伸の方法は通常の方法でよく、加
熱装置（６）で加熱し、ロール（７）で引張るだけでよ
い。(4) Stretching 1. The stretching method may be any conventional method, and it is sufficient to simply heat it with a heating device (6) and pull it with a roll (7).
（５） 加熱空隙を通過させる。(5) Pass through the heating gap.
加熱収束装置（８）の空隙の径は、１．０〜１．５ｍｍ
程度がよい、勿論、この径は、膨出の径や厚みによるが
、出来上がりの模造イグサの径、充填率（後述する）に
よって決定されるべきものである。The diameter of the gap in the heating convergence device (8) is 1.0 to 1.5 mm.
Of course, this diameter depends on the diameter and thickness of the bulge, but should be determined by the diameter and filling rate of the finished imitation rush (described later).
加熱の温度としては、４００℃〜５００℃程度が好まし
い。The heating temperature is preferably about 400°C to 500°C.
通過速度は、５０〜１００ｍ／分程度でよい。The passing speed may be about 50 to 100 m/min.
（６）通過後、フィルムは、空隙径よりも膨張するため
、はぼ１．５ｍｓ程度の径になる。(6) After passing, the film expands more than the gap diameter, so the diameter becomes approximately 1.5 ms.
模造イグサとしての最も重要な点、即ち、風合や外観が

見いだした点が本発明のスタートでもある。この充填率
の求め方は次のようになる０例えば、直径２００ｍ５、
厚さ０．０５ｍ５の中空フィルムを５．０倍に延伸した
ものを収束させて、直径３ＩＩ−のイグサを製造した場
合には、充填率は次のように計算される。The most important point for imitation rushes is that their texture and appearance are similar to natural rushes. It is desirable to have one. The filling rate here refers to the cross-sectional area of the film itself divided by the cross-sectional area of the finished rush, and is the ratio of the film to the cross-section of the rush. The present invention was based on the discovery that when the filling rate is 70% to 90%, the texture and appearance are very similar to those of natural materials. The method of calculating this filling rate is as follows.0For example, if the diameter is 200m5,
When a rush having a diameter of 3II- is produced by converging a hollow film with a thickness of 0.05 m5 stretched 5.0 times, the filling rate is calculated as follows.
２００ Ｘ３．１４Ｘ０．０５＋５−６．３３ Ｘ３
Ｘ３．１４÷４ −７．１６．３ ÷７．１ −０
．８９
よって、この例では充填率が８９％となる。200 X3.14X0.05+5-6.33 X3
X3.14÷4 -7.16.3 ÷7.1 -0
．． 89 Therefore, in this example, the filling rate is 89%.
充填率自体は、６０％〜９５％程度であることが必要で
あり、好ましくは前記した如く７０〜９０％である。The filling rate itself needs to be about 60% to 95%, preferably 70 to 90% as described above.
結局、この模造イグサを天然品に近づけるためには、次
の性質が所定の範囲内にあることが望ましいということ
となる。In the end, in order to make this imitation rush closer to a natural product, it is desirable that the following properties fall within a predetermined range.
■ 製品の直径は、１．５ｓｖ＋〜３．５閘■ 充填率
は、７０％〜９０％
■ フィルムの厚さは、１０μ〜３０μこの模造イグサ
は、通常の畳表や鐘に使用できるばかりでなく、わら等
の代用品としても使用できるものである。■ The diameter of the product is 1.5 sv + ~ 3.5 sq. ■ The filling rate is 70% ~ 90% ■ The thickness of the film is 10 μ ~ 30 μ This imitation rush can not only be used for regular tatami mats and bells. It can also be used as a substitute for straw, etc.
