Abstract
Description
【０００１】
【発明の属する技術分野】
本発明は、キチン・キトサン内填紙を用いた編織物およびその製造方法に関する。
【０００２】
【従来の技術】
従来、靴下や下着等の繊維製品にキチン・キトサンを含有させた新たな機能性製品が提案されている。キチン・キトサンは、生分解性・生体適合性・抗菌性・防臭性（消臭性）・吸湿性・帯電防止性・染色性等の面で優れた機能を有しており、かかる機能を各種繊維製品に付与する試みがなされてきた。
【０００３】
例えば、特許文献１から５には、キチン・キトサン単独あるいはキチン・キトサンとセルロースとを混合して湿式紡糸することにより、キチン・キトサンを繊維化する試みが記載されている。
【０００４】
【発明が解決しようとする課題】
しかし、キチン・キトサンそのものの繊維化あるいはキチン・キトサンと他の繊維との混合紡糸には各種化学プロセスを経る必要があり、コスト面あるいは効率面で決して有利とはいえなかった。
【０００５】
また、技術的にも、繊維材料としての十分な強度を確保しつつキチン・キトサンの効果を十分に発揮させるには、克服すべき課題も多く、大量生産に向くとは言い難い面があった。
【０００６】
本発明は、かかる課題に鑑み、より簡便な方法で、繊維材料に必要な強度を確保しつつキチン・キトサンの効果を十分に発揮する編織物およびその製造方法を提供することを目的とする。
なお、本明細書における「キチン・キトサン」との表記には、キチンとキトサンの両方を含む場合だけでなく、キチン単独またはキトサン単独の場合も含まれる。また、これらの誘導体も含まれる。

【課題を解決するための手段】
請求項１に記載の発明は、キチン・キトサン内填紙からなる紙糸を構成糸として含むことを特徴とする編織物である。
【０００９】
本発明において、キチン・キトサン内填紙とは、紙基材にキチン・キトサン微粉末を内填させたものをいい、紙の製造工程において、キチン・キトサンを溶液化したものを紙基材に混合するのではなく、キチン・キトサンの微粉末を混抄させた紙をいう。本出願人が先に出願した特許文献６には、かかるキチン・キトサン内填紙が例示されている。
【００１０】
このキチン・キトサン内填紙は、紙基材にキチン・キトサンを微粉末にして内填するものであり、高濃度のキチン・キトサンの広範囲での利用を可能にするものである。内填にあたっては、紙の調成工程で紙基材にキチン・キトサン微粉末を混抄させるだけで、従来の紙の特性を損なわずしかも表面にザラ付きのない紙製品を得ることができる。また、キチン・キトサンの微粉末を使用するため、紙基材内におけるキチン・キトサンの表面積が大きくなり、その分キチン・キトサンの内填量の節約が図れるとともに、キチン・キトサンの抗菌、防臭といった特性を最大限に発揮できるものである。さらに、製造工程において、キチン・キトサンを溶解して溶液にしたり、各種薬品や樹脂等を添加する必要がないので、製造上の作業工程が少なくなり、その分作業時間の短縮化とコストダウンが図れ、また、キチン・キトサンを溶解する溶剤や、薬品等の添加がないので、人体に対して安全な紙製品が得られ、二次公害を引き起こすおそれもない。
【００１１】
ここで、キチン・キトサン微粉末は２５ミクロン〜１５０ミクロン（５００メッシュ〜１００メッシュ）であることが好ましく、特に６０ミクロン〜１００ミクロン（２３５メッシュ〜１５０メッシュ）であることが好ましい。キチン・キトサンの分子量は５万〜２００万のものが好ましい。脱アセチル化度は１０％以上が好ましく、特に７０％以上であることが好ましい。キチン・キトサンの効果を十分に発揮するには、キチン・キトサン微粉末の内填率は少なくとも０．３％以上であることが好ましい。特に抗菌特性が必要な場合には、内填率は０．５％以上であることが好ましい。一般的には、キチン・キトサン微粉末の内填率は０．５〜１０％が好ましい。
【００１２】
なお、キチン・キトサンの分子量、脱アセチル化度、微粉末粒子の大きさ等は、上記範囲内で使用目的に応じて適宜選択すればよく、例えば、抗菌特性にあっては、キチン・キトサンの分子量は５万〜３０万、脱アセチル化度は８５％前後が特に好ましい。一方、防臭特性にあっては、キチン・キトサンの分子量は１０万〜２０万、脱アセチル化度は７０％前後が特に好ましい。
【００１３】
請求項１に記載の編織物は、上記のキチン・キトサン内填紙を、例えば細長く裁断してこれを紙糸となし、この紙糸を編織することにより得られる。
キチン・キトサン内填紙を使用した紙糸は、カチオン性物質のキチン・キトサンとアニオン性物質のセルロースとのイオン結合により、従来の紙糸よりも強度が高く、編織過程での糸切れも少ない。このため、織り易さや編み易さが向上して作業効率が向上し、また、糸切れして廃棄される紙糸の削減にも寄与する。さらに、キチン・キトサン内填紙を使用しているため抗菌性や防臭性といった効果を編織物に付与することができる。
【００１４】
なお、請求項１の編織物に使用される紙糸は、キチン・キトサン内填紙を抄造後に細長く裁断したものに限られず、キチン・キトサン内填紙を初めから細長形状に成形したものも含まれる。また、加燃していない扁平形状の紙糸だけでなく、加撚したものも含まれる。
【００１５】
上記請求項１の発明では、かかる紙糸を経糸・緯糸のいずれにも使用することができる。また、綿や絹等と混織または混編してもよく、さらに、上記紙糸のみを編織してもよい。綿や絹等と混織または混編すれば、繊維製品としてより優れたものを得ることができる。特に、生分解性繊維とともに混編織すれば、出来上がった編織物も生分解性に優れることになり、環境に害を与えない製品が得られる。
【００１６】
この請求項１の編織物は、請求項２に記載したように、キチン・キトサン内填紙をカレンダー処理したものを裁断して紙糸となし、この紙糸を編織してもよい。カレンダー処理することにより、内填紙中のセルロース繊維がより密着し機械的強度が向上するだけでなく、キチン・キトサンの接触面積が増加して抗菌性等の効果をより発揮することができる。また、カレンダー処理により光沢や耐水性・透気度も増す。
【００１７】
請求項３に記載の発明は、前記請求項１に係る編織物を製造する方法の一つであって、紙の調成工程で紙基材にキチン・キトサン微粉末を混合してキチン・キトサン内填紙を抄造する工程と、上記工程で得られたキチン・キトサン内填紙を細長く裁断する裁断工程と、上記裁断工程で得られた紙糸を使用して編織物を編織する編織工程とを備えたことを特徴とする。
【００１８】
請求項４に記載の発明は、上記請求項３に記載の編織物の製造方法において、キチン・キトサン内填紙を抄造した後カレンダー処理し、このカレンダー処理したキチン・キトサン内填紙を細長く裁断して紙糸となし、この紙糸を使用して編織物を編織することを特徴とする。上記カレンダー処理に際しては、８０〜１００℃の温度条件の下で２５０〜３００ｋｇ／ｃｍ３の圧力を加えることが好ましい。特に、温度条件については８０〜９０℃が好ましい。
【００１９】
このように、本発明に係る編織物は、キチン・キトサン内填紙からなる紙糸を編織しているので、湿式紡糸法等によるキチン・キトサンの繊維化という工程を経ることなく、キチン・キトサンの効果を十分に発揮できる編織物を簡便かつ低コストで得ることができる。
【００２０】
【発明の実施の形態】
以下、本発明の実施形態について説明する。
キチン・キトサン内填紙は、上述したように、紙基材にキチン・キトサンの微粉末を内填させたものを使用する。キチン・キトサンの分子量、脱アセチル化度、微粉末粒子の大きさ、内填率等は上記の範囲内で適宜選択すればよい。また、キチン・キトサン内填紙は、和紙あるいは洋紙のいずれに抄造してもよい。
【００２１】
このキチン・キトサン内填紙を、例えば適当な幅で細長く裁断して扁平形状の紙糸を作る。裁断幅は用途や目的に応じて適当な幅を選択すればよいが、２〜１０ｍｍが好ましい。
【００２２】
この扁平形状の紙糸をそのまま使用するか、あるいは、この扁平糸に撚りを加えた撚糸を使用して編織する。撚り数・仕上がり糸径等は、用途や目的にあわせて適宜選択すればよい。
【００２３】
本発明の編織物は、このような扁平糸または撚糸を、手作業で、または、編機もしくは織機を用いて編織することで得られる。この編織工程は通常の編織紙布を製造する工程と変わるところはなく、用途や目的にあわせて編構造または織構造を選択すればよい。その際、綿や絹等の他の材質の糸とともに混編織すれば繊維製品としてより優れたものが得られる。例えば、上記の扁平糸または撚糸を緯糸に使用し、経糸には木綿糸または絹糸を用いて従来の紙布の製造と同じ要領で織り上げれば、生分解性・生体適合性・抗菌性・防臭性（消臭性）・吸湿性・帯電防止性・染色性等の面で従来にない編織物を得ることができる。
【００２４】
本発明の編織物は、編織後の仕上作業として、編織物を叩いてほぐす作業を加えてもよい。これにより、摩擦強度が向上するとともに、肌触りが柔らかくなりゴワゴワした感じがなくなる。
【００２５】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a knitted fabric using chitin / chitosan-filled paper and a method for producing the same.
[0002]
[Prior art]
BACKGROUND ART Conventionally, new functional products have been proposed in which chitin and chitosan are contained in fiber products such as socks and underwear. Chitin and chitosan have excellent functions in terms of biodegradability, biocompatibility, antibacterial properties, deodorant properties (deodorant properties), moisture absorption properties, antistatic properties, dyeing properties, etc. Attempts have been made to apply it to textiles.
[0003]
For example, Patent Documents 1 to 5 describe attempts to fiberize chitin / chitosan by wet spinning using chitin / chitosan alone or a mixture of chitin / chitosan and cellulose.
[0004]
[Problems to be solved by the invention]
However, fiberization of chitin / chitosan itself or spinning of a mixture of chitin / chitosan and other fibers requires various chemical processes, which has never been advantageous in terms of cost or efficiency.
[0005]
In addition, technically, there were many issues to be overcome in order to fully exert the effects of chitin and chitosan while securing sufficient strength as a fiber material, and it was difficult to say that it would be suitable for mass production. .
[0006]
The present invention has been made in view of the above problems, and has as its object to provide a knitted woven fabric that sufficiently exerts the effects of chitin and chitosan while ensuring the strength required for a fiber material, and a method for producing the same, with a simpler method.
The expression “chitin / chitosan” in the present specification includes not only a case including both chitin and chitosan but also a case including chitin alone or chitosan alone. Also, these derivatives are included.

[Means for Solving the Problems]
The invention according to claim 1 is a knitted woven fabric comprising a paper thread composed of chitin / chitosan-filled paper as a constituent thread.
[0009]
In the present invention, the chitin / chitosan-filled paper refers to a paper base in which chitin / chitosan fine powder is filled, and in the paper manufacturing process, a solution in which chitin / chitosan is converted to a paper base. Rather than mixing, it refers to paper mixed with fine powder of chitin / chitosan. Patent Document 6 filed earlier by the present applicant exemplifies such a chitin-chitosan-filled paper.
[0010]
The chitin / chitosan-filled paper is a paper in which chitin / chitosan is finely powdered and filled into a paper base material, and enables the use of high-concentration chitin / chitosan in a wide range. At the time of filling, a paper product which does not impair the characteristics of the conventional paper and has no rough surface can be obtained only by mixing chitin / chitosan fine powder with the paper base in the paper preparation step. In addition, the use of chitin / chitosan fine powder increases the surface area of chitin / chitosan in the paper base material, thereby saving the amount of chitin / chitosan loaded, and improving the antibacterial and deodorizing properties of chitin / chitosan. The characteristics can be maximized. Furthermore, in the manufacturing process, there is no need to dissolve chitin / chitosan into a solution or add various chemicals or resins, so the number of manufacturing steps is reduced, and the working time and cost are reduced accordingly. Further, since there is no addition of solvents or chemicals for dissolving chitin / chitosan, a paper product safe for the human body is obtained, and there is no possibility of causing secondary pollution.
[0011]
Here, the chitin / chitosan fine powder preferably has a size of 25 to 150 microns (500 to 100 mesh), and particularly preferably 60 to 100 microns (235 to 150 mesh). The molecular weight of chitin / chitosan is preferably from 50,000 to 2,000,000. The degree of deacetylation is preferably at least 10%, particularly preferably at least 70%. In order to sufficiently exert the effect of chitin / chitosan, the filling rate of chitin / chitosan fine powder is preferably at least 0.3% or more. In particular, when antibacterial properties are required, the filling rate is preferably 0.5% or more. Generally, the filling rate of chitin / chitosan fine powder is preferably 0.5 to 10%.
[0012]
The molecular weight of chitin / chitosan, the degree of deacetylation, the size of the fine powder particles, etc. may be appropriately selected according to the intended use within the above range.For example, in the case of antibacterial properties, chitin / chitosan It is particularly preferred that the molecular weight is 50,000 to 300,000 and the degree of deacetylation is around 85%. On the other hand, in terms of deodorant properties, it is particularly preferable that the molecular weight of chitin / chitosan is 100,000 to 200,000 and the degree of deacetylation is around 70%.
[0013]
The knitted fabric according to the first aspect is obtained by, for example, cutting the above-mentioned chitin / chitosan-filled paper into a long and thin form into a paper thread, and weaving the paper thread.
Paper yarn using chitin-chitosan-filled paper has higher strength than conventional paper yarn due to the ionic bond between the cationic substance chitin-chitosan and the anionic substance cellulose, and has less yarn breakage during the weaving process. . For this reason, the easiness of weaving and knitting is improved, so that the working efficiency is improved, and the thread contributes to a reduction in the amount of paper thread that is broken and discarded. Furthermore, the use of chitin / chitosan-filled paper makes it possible to impart effects such as antibacterial properties and deodorant properties to the knitted fabric.
[0014]
In addition, the paper thread used for the knitted fabric of claim 1 is not limited to the one obtained by cutting the chitin-chitosan-filled paper into an elongated shape after papermaking, but also includes the one formed from the chitin-chitosan-filled paper into an elongated shape from the beginning. It is. In addition, not only flat paper yarn that is not burned but also twisted yarn is included.
[0015]
According to the first aspect of the present invention, the paper yarn can be used for both warp and weft. Further, it may be knitted or knitted with cotton, silk, or the like, and further, only the paper yarn may be knitted. By blending or knitting with cotton, silk, or the like, a more excellent fiber product can be obtained. In particular, if the knitted fabric is mixed and knitted together with the biodegradable fiber, the finished knitted fabric has excellent biodegradability, and a product that does not harm the environment can be obtained.
[0016]
In the knitted fabric according to the first aspect, as described in the second aspect, a sheet obtained by calendering the chitin / chitosan-filled paper may be cut into a paper thread, and the paper thread may be knitted. By performing the calendering treatment, not only the cellulose fibers in the inner paper can be more closely adhered to each other to improve the mechanical strength, but also the contact area between chitin and chitosan can be increased to exhibit more effects such as antibacterial properties. In addition, calendering increases gloss, water resistance, and air permeability.
[0017]
The invention according to claim 3 is one of the methods for producing the knitted fabric according to claim 1, wherein chitin / chitosan fine powder is mixed with a paper base in a paper preparation step. A step of making an inner filling paper, a cutting step of cutting the chitin / chitosan inner filling paper obtained in the above step into a slender form, and a weaving step of knitting a knitted woven fabric using the paper yarn obtained in the above cutting step. It is characterized by having.
[0018]
According to a fourth aspect of the present invention, in the method for producing a knitted woven fabric according to the third aspect, after the chitin / chitosan-filled paper is formed, the paper is calendered, and the calendered chitin / chitosan-filled paper is cut into an elongated shape. The knitted fabric is knitted and woven using the paper yarn. At the time of the calendering treatment, it is preferable to apply a pressure of 250 to 300 kg / cm 3 under a temperature condition of 80 to 100 ° C. Particularly, the temperature condition is preferably 80 to 90 ° C.
[0019]
As described above, since the knitted fabric according to the present invention is knitted and woven with the paper thread composed of the chitin / chitosan-filled paper, the chitin / chitosan can be converted into a fiber without chitin / chitosan by a wet spinning method. Can be obtained simply and at low cost.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
As described above, the chitin / chitosan-filled paper is a paper base in which fine powder of chitin / chitosan is filled. The molecular weight of chitin / chitosan, the degree of deacetylation, the size of fine powder particles, the filling rate, etc. may be appropriately selected from the above ranges. The paper with chitin / chitosan may be made into either Japanese paper or Western paper.
[0021]
The chitin-chitosan-filled paper is cut into a long and thin shape with an appropriate width, for example, to produce a flat paper thread. The cutting width may be appropriately selected depending on the application and purpose, but is preferably 2 to 10 mm.
[0022]
The flat paper yarn is used as it is, or the flat yarn is knitted or woven using a twisted yarn obtained by adding twist. The number of twists, the finished yarn diameter, etc. may be appropriately selected according to the application and purpose.
[0023]
The knitted fabric of the present invention is obtained by weaving such a flat yarn or twisted yarn manually or by using a knitting machine or a loom. This knitting step is not different from the step of manufacturing a normal knitted paper cloth, and the knitting structure or the woven structure may be selected according to the use or purpose. In this case, if the fabric is mixed and knitted with yarn of another material such as cotton or silk, a more excellent fiber product can be obtained. For example, if the above-mentioned flat yarn or twist yarn is used for the weft and cotton yarn or silk yarn is used for the warp and woven in the same manner as in the production of conventional paper cloth, biodegradability, biocompatibility, antibacterial properties, and deodorization It is possible to obtain a knitted fabric which has never been seen in terms of properties (deodorizing property), hygroscopicity, antistatic property, dyeing property and the like.
[0024]
The knitted fabric of the present invention may include an operation of hitting and loosening the knitted fabric as a finishing operation after the knitting. As a result, the frictional strength is improved, and the touch is softened, and the feeling of rough feeling is eliminated.
[0025]
