Description

本発明は、植物ケナフの靭皮の繊維を用いたケナフ糸の製造方法と該方法により製造したケナフ糸に関する。  The present invention relates to a method for producing a kenaf yarn using fibers of a bast of plant kenaf and a kenaf yarn produced by the method.

ケナフは、世界中、特に、南米、東南アジア、中国等において多量に栽培されている植物で、3〜4メートル程度に成長し、古くはその靭皮が強力であるところから、麻と同様に綱を撚ったりして利用されてきたが、昨今は、木と同様に酸素供給源として、地球環境の改善に適した素材提供源として注目されているものである。  Kenaf is a plant that is cultivated in large quantities in the world, especially in South America, Southeast Asia, China, etc., and it grows to about 3 to 4 meters. In recent years, it has been attracting attention as a material supply source suitable for improving the global environment as an oxygen supply source in the same manner as trees.

また、最近に至っては、ケナフ繊維を撚って織物用糸を製造し、衣料用として使用することが提案されている。

上述のように、ケナフ繊維が織物用糸或いはケナフ紙として使用することが出来ること、また、天然繊維であるところから、廃棄したときに自然に回帰することができて、環境汚染の心配がないという自然に優しい繊維であるところから、今後の研究開発の期待が出てきている。  As described above, the kenaf fiber can be used as textile yarn or kenaf paper, and since it is a natural fiber, it can return to nature when discarded, and there is no concern about environmental pollution. Because of the nature-friendly fiber, expectations for future research and development are emerging.

これまでに提案されているケナフ糸を用いた生地は、麻と同様に天然繊維としての柔らかさを持つと共に麻よりも更に柔らかな風合いを持つことが判っている。
その反面、麻に比べて強度が小さく、衣料用として用いるには不適切であることも判って来ている。
従って、これまで提案されてきたケナフ繊維を用いた糸によって織製された生地で衣類を製造しても、他の天然繊維や化繊のように充分な強度が得られず、そのケナフ繊維糸の使用対象が極く僅かなものに限定されるものであった。
It has been found that fabrics using kenaf yarn proposed so far have softness as natural fibers as well as hemp and a softer texture than hemp.
On the other hand, it has been found that the strength is lower than that of hemp and it is inappropriate for use as clothing.
Therefore, even if a garment is manufactured with a fabric woven with yarns using kenaf fibers that have been proposed so far, sufficient strength cannot be obtained as with other natural fibers or synthetic fibers, and the kenaf fiber yarns The object of use was limited to very few.

本発明は、かかる問題点に鑑み、ケナフ糸が充分な強度を持つようにすること、及び織成生地及び編成生地として、柔らかな風合いを残しながら十分な強度を発揮でき、天然繊維としての吸湿性と水分の発散機能を備えて、衣料用等の目的で使用できるところのケナフ糸の製造方法と該方法により製造されたケナフ糸を提供することを目的とする。  In view of such problems, the present invention makes it possible for the kenaf yarn to have sufficient strength, and as a woven fabric and a knitted fabric, can exhibit sufficient strength while leaving a soft texture, and absorbs moisture as a natural fiber. An object of the present invention is to provide a method for producing a kenaf yarn, which has a property and a function of spreading moisture and can be used for clothing, and a kenaf yarn produced by the method.

本発明にかかるケナフ糸の製造方法は、上記目的を達成するために、ケナフを水煮又は/及び破砕によって靭皮の繊維を採取し、このケナフ繊維からケナフ糸を製造する方法であって、
採取したケナフ繊維に、マニラ麻繊維を重量比で50%〜70%混合し、少なくとも繊維分散剤として澱粉系糊を混入して攪拌し、
少なくとも円網抄き工程を経て、目付けが12g/m〜25g/mの薄手の長尺の紙を製造し、
製造された紙を、スリット幅が1mm〜5mmの紙片となるように裁断し、
裁断した紙片に400回〜800回の撚りをかけることによって糸を製造する、という手段を講じたものである。
A method for producing a kenaf yarn according to the present invention is a method for producing a kenaf yarn from the kenaf fiber by collecting bast fibers by boiling or / and crushing the kenaf to achieve the above object,
Mixing 50% to 70% by weight of Manila hemp fiber to the collected kenaf fiber, mixing at least starch paste as a fiber dispersant and stirring,
Via at least round net paper making process, basis weight to produce a thin elongated paper 12g / m 2 ~25g / m 2 ,
The manufactured paper is cut so that the slit width is 1 mm to 5 mm,
A measure is taken in which a yarn is produced by twisting a cut piece of paper 400 to 800 times.

このように、ケナフ繊維を30%乃至50%用いて、出来上がった糸にケナフ繊維の軟らかな風合いを発現させながら、円網抄き工程によって、ケナフ繊維を主に縦方向に並べて糸の長手方向に強度を持たせた目付けが12g/m〜25g/mの薄手の長尺の紙を製造することができ、この後の1mm〜5mm幅のスリットと、400回〜800回の十分な撚りをかけることができて、被服等にも使用し得る強度のあるケナフ糸が得られたのである。In this way, using kenaf fibers of 30% to 50%, while producing a soft texture of the kenaf fibers in the finished yarn, the kenaf fibers are arranged mainly in the longitudinal direction by the circular net making process, and the longitudinal direction of the yarn the basis weight which gave strength can be produced a thin elongated paper 12g / m 2 ~25g / m 2 , and the slit of 1mm~5mm width Thereafter, 400 times 800 times sufficient A strong kenaf yarn that can be twisted and used for clothing and the like was obtained.

そして、本発明にかかるケナフ糸は、上記目的を達成すするために、請求項1乃至請求項3の製造方法によって製造される。このようなケナフ糸は、そのまま用いて織成又は編成して被服等に用いることができ、また、該ケナフ糸を縦糸又は横糸として用い、化繊糸又は天然糸と混紡して織成又は編成することによって被服等に用いることができる。  And the kenaf yarn concerning this invention is manufactured by the manufacturing method of Claim 1 thru | or 3 in order to achieve the said objective. Such a kenaf yarn can be used as it is for knitting or knitting and used for clothing, etc. Also, the kenaf yarn can be used as warp or weft, blended with synthetic fiber or natural yarn, and knitted or knitted. Can be used for clothing.

本発明によれば、ケナフ繊維を用いたケナフ糸でありながら、天然繊維としての吸湿性と水分の発散機能を備え、ケナフ独特の柔らかな風合いを発現しつつ、これまでのケナフ糸では得られなかった充分な強度を有するので、衣料等の具体的実用商品に適用できる利点がある。  According to the present invention, although it is a kenaf yarn using kenaf fiber, it has a hygroscopic property as a natural fiber and a moisture divergence function, and exhibits a soft texture peculiar to kenaf. Since it has sufficient strength, there is an advantage that it can be applied to specific practical products such as clothing.

請求項1のように、ケナフ繊維とマニラ麻繊維の混合に際して、繊維分散剤としての澱粉系糊を用いると共に、少なくとも円網の抄き工程(円網のドラムによる)を経ることで、特にケナフ繊維が主に縦方向に並び易くなり、縦方向、即ち、抄き紙を長尺にスリットしたときの長手方向での強度が増加され、400回〜800回の撚りをかけたときに充分に耐えることが出来て、十分な撚りを得ることができ、その結果強度のあるケナフ糸が製造できるのである。  When mixing kenaf fiber and manila hemp fiber as in claim 1, starch paste as a fiber dispersant is used, and at least through a circular mesh making process (by a circular drum), particularly kenaf fiber Becomes easier to align mainly in the vertical direction, the strength in the vertical direction, that is, the longitudinal direction when the paper is slit in a long length is increased, and it is sufficiently resistant when twisted 400 to 800 times. And a sufficient twist can be obtained, so that a strong kenaf yarn can be produced.

そして、製造されたケナフ糸を織物として使用するためには、細い糸でなければならず(例えば、10番手から20番手の糸)、そのためには、原材料として抄いた紙の目付けも小さなものとし、スリットの幅も狭くする(1mm〜5mm)という必要性がある反面、これに十分な撚りをかける必要性があるため、その薄く、細い紙片に十分な強度が求められるのであるが、本発明によれば、こうした要求を満たすことが出来たのである。そして、上述のように、スリットされた細片に対する撚りを、400回乃至800回とすることで、充分な強度と細さを確保できて、麻糸等の一般天然繊維の糸と差異のないケナフ糸が得られる。  In order to use the manufactured kenaf yarn as a woven fabric, it must be a thin yarn (for example, 10th to 20th yarn), and for this purpose, the basis weight of the paper made as a raw material should be small. Although the width of the slit is also required to be narrow (1 mm to 5 mm), it is necessary to apply sufficient twist to the slit. Therefore, sufficient strength is required for the thin and thin paper piece. According to, he was able to meet these requirements. Then, as described above, the twist on the slit strip is set to 400 to 800 times, so that sufficient strength and thinness can be secured, and there is no difference from yarns of general natural fibers such as hemp yarn. Yarn is obtained.

また、本発明においては、ケナフ繊維の相手としてマニラ麻繊維を使用しているが、これに代えて、みつまた、コーゾ又はその組み合わせとすることも可能であり、これらは、ケナフ繊維との相性がよく、繊維同士の絡みが充分に得られる。その他、場合によっては、綿等も添加することも可能である。
また、上記円網抄き工程に続けて長網抄き工程を用いた場合、ケナフ繊維及びマニラ麻繊維が主に縦に並ぶ円網抄き工程による紙層と、それら繊維がアトランダムの状態に並ぶ長網抄き工程による紙層が積層状態となり、撚りに必要な縦方向(スリット片の長手方向)の強度が得られるのは勿論のこと、横方向の強度も十分に得られ、原紙としての強度が非常に向上するので撚り加工に好適である。
Further, in the present invention, Manila hemp fiber is used as the partner of kenaf fiber, but instead of this, it is also possible to use honey or cozo or a combination thereof, which has good compatibility with kenaf fiber. The fibers are sufficiently entangled. In addition, depending on the case, cotton or the like can be added.
In addition, when a long net making process is used following the above circular net making process, a paper layer by a circular net making process in which kenaf fibers and manila hemp fibers are mainly arranged vertically, and these fibers are in an at random state. The paper layers from the long net making process are stacked, and the strength in the longitudinal direction (longitudinal direction of the slit pieces) required for twisting is obtained, as well as sufficient strength in the transverse direction. Is very suitable for twisting.

そして、請求項1乃至請求項3の方法によって製造されたケナフ糸を縦糸又は横糸として用いて織成又は編成された織成生地は、充分な強度を備えることができて、被服、タペストリー等、種々の用途に用いることが出来る。
尚、織成に代えて編成生地を得ることもできる。
The woven fabric woven or knitted using the kenaf yarn produced by the method of claims 1 to 3 as warp or weft can have sufficient strength, such as clothing, tapestry, etc. It can be used for various purposes.
A knitted fabric can be obtained instead of weaving.

ここでは、ケナフの靭皮から繊維を抽出するのに、水煮及び破砕工程を用いて行うが、この工程は、既存の方法であるので、詳細説明を省く。この他の方法としては、古くから、水桶、池等にケナフを投入し、自然腐敗を進行させて繊維を抽出するという方法もある。  Here, extraction of fibers from kenaf bast is performed using a boiled and crushing step, but this step is an existing method and will not be described in detail. As another method, there is also a method in which kenaf is introduced into water tanks, ponds, etc., and fiber is extracted by causing natural decay.

上記方法で採取されたケナフ繊維に、別途準備した天然繊維、ここではマニラ麻の繊維を、重量比で70%混合させ、結合目的と合わせて繊維を分散させる機能を発揮する澱粉系糊(芋等から精製)を混入して攪拌を行った。
そして、この原料パルプを円網抄き装置に送り、回転ドラムの表面に、その円周方向、即ち、製造する原紙の長尺方向(縦に)ケナフ繊維及び麻繊維が並ぶ姿勢で抄かれていく。
ここでの目付は、15g/mに調整され、所定の乾燥工程を経て、ドラムに巻き取られる。
