Description
本発明は、紙撚糸、紙撚糸の製造方法、及び紙撚糸を用いた織物に関するものである。 The present invention relates to a paper twisted yarn, a method for producing the paper twisted yarn, and a woven fabric using the paper twisted yarn.
セルロース繊維の集合体によって形成された帯状の紙材を撚ることで糸状体とし、この糸状体を用いて形成した織物は、軽く、吸湿性、速乾性が高く、しかも風合いも良いとされ、脚光を浴びている。
また、紙材の表面に、光触媒粒子を付着させることで、抗菌、殺菌、脱臭効果を持たせることも知られている（特許文献１、２）。
By twisting a strip of paper material formed by an aggregate of cellulose fibers into a filament, the woven fabric formed using this filament is light, has high moisture absorption, fast drying, and is said to have a good texture, It is in the spotlight.
It is also known that photocatalyst particles are attached to the surface of paper to provide antibacterial, sterilizing, and deodorizing effects (Patent Documents 1 and 2).
しかしながら、上記した特許文献１、２は、紙材の表面に、光触媒粒子を付着させる技術である。このため、この技術を利用して前記糸状体に光触媒粒子を付着させることを考えた場合、光触媒粒子を、糸状体の表面に塗布することになる。 However, Patent Documents 1 and 2 described above are techniques for attaching photocatalyst particles to the surface of a paper material. Therefore, in the case where the photocatalyst particles are attached to the filament using this technique, the photocatalyst particles are applied to the surface of the filament.
そして、この糸状体を用いて織物を作成すると、糸状体が織物の表面に位置するため、糸状体の表面に塗布された光触媒粒子も織物の表面に露出することになる。この結果、光触媒による光触媒効果（抗菌、殺菌、脱臭効果）も期待できる。 Then, when a woven fabric is formed using the filament, the filament is located on the surface of the woven fabric, so that the photocatalyst particles applied to the surface of the filament are also exposed on the surface of the woven fabric. As a result, a photocatalytic effect (antibacterial, sterilizing, deodorizing effect) by the photocatalyst can be expected.
しかしながら、光触媒粒子を、糸状体の表面に塗布した場合、糸状体の表面に光触媒粒子が付着しただけの状態であるので、例えば、糸状体に他のものがこすれたり、あるいは洗濯をしたりすると、糸状体の表面に付着させた光触媒粒子は、糸状体の表面から剥がれ落ちてしまい、その結果として、長期的な光触媒効果が期待出来ないものとなる。 However, when the photocatalyst particles are applied to the surface of the filament, the photocatalyst particles are merely attached to the surface of the filament, so that, for example, if the filament is rubbed with other things or is washed In addition, the photocatalyst particles attached to the surface of the filament are peeled off from the surface of the filament, and as a result, a long-term photocatalytic effect cannot be expected.

以下、本発明の一実施形態を、添付図面も参照して詳細に説明する。本実施の形態によれば、例えば、糸状体に接着剤で複数の光触媒粒子を付着させるだけではなく、この光触媒粒子は、糸状体の表面よりも、内部に多く配設しているため、糸状体に、他のものがこすれたり、あるいは洗濯したりしても、糸状体内部に多くの光触媒粒子を保持させた状態を維持でき、脱落することは極めて少なく、これにより、糸状体は長期的に、大量の光触媒粒子を保持した状態となる。 Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. According to the present embodiment, for example, not only a plurality of photocatalyst particles are attached to the filament with an adhesive, but the photocatalyst particles are disposed more inside the filament than on the surface of the filament. Even if the body is rubbed or washed with other things, the state in which many photocatalyst particles are held inside the filament can be maintained, and the filament is very unlikely to fall off. Then, a large amount of photocatalyst particles is held.
また、紫外線の糸状体内部への浸透性は高いので、糸状体の内部に多く保持された光触媒粒子による光触媒効果が長期的に発揮されることになる。
（実施の形態１）
In addition, since the ultraviolet rays have high permeability into the filament, the photocatalytic effect of the photocatalyst particles held in the filament in a large amount can be exhibited for a long time.
(Embodiment 1)
本実施形態の紙撚糸は、例えば、複数の光触媒粒子を、接着剤などにより付着させた帯状の紙材を、撚りをかけて形成した、直径が１００μｍ〜４００μｍの糸状である。
図１に示すフローチャートに従って具体的な製造方法を説明する。図１は本実施形態の紙撚糸及び該糸を用いた織物の製造方法を説明するためのフローチャートである。
The paper twist yarn of the present embodiment is, for example, a yarn having a diameter of 100 μm to 400 μm formed by twisting a belt-shaped paper material to which a plurality of photocatalyst particles are attached by an adhesive or the like.
A specific manufacturing method will be described according to the flowchart shown in FIG. FIG. 1 is a flowchart for explaining a paper twisted yarn of this embodiment and a method for manufacturing a woven fabric using the yarn.
先ず、ステップＳ１において紙状体を形成する紙状体形成工程を実行する。例えば、マニラ麻パルプを用い、一般的な抄紙法で、厚さが、１５μｍ〜５０μｍの紙状体を形成する。 First, in step S1, a paper-like body forming step of forming a paper-like body is performed. For example, a paper-like body having a thickness of 15 μm to 50 μm is formed by a general papermaking method using manila hemp pulp.
この紙状体は十分に乾燥したものとし、次に、ステップＳ３に示す塗工液塗布工程を行う。具体的には、紙状体の裏面側から、光触媒粒子と接着剤を含む塗工液を塗布する。
光触媒粒子としては、例えば、富士化学社製チタンアパタイト（商品名：ハウトフォームＴＡ）を０．１ｗｔ％以上２０ｗｔ％以下（最適には例えば５％〜１０％ｗｔ％）用いる。また、接着剤としては、架橋性ポリビニルアルコール（以下「ＰＶＡ」と称す。）を、０．０５ｗｔ％以上５ｗｔ％以下（最適には１％〜２％ｗｔ％）を用いる。
The paper is sufficiently dried, and then a coating liquid application step shown in step S3 is performed. Specifically, a coating liquid containing photocatalyst particles and an adhesive is applied from the back side of the paper-like body.
As the photocatalyst particles, for example, titanium apatite (trade name: Houtform TA) manufactured by Fuji Chemical Co., Ltd. is used in an amount of 0.1% by weight or more and 20% by weight or less (optimally, for example, 5% to 10% by weight). As the adhesive, a crosslinkable polyvinyl alcohol (hereinafter referred to as “PVA”) is used in an amount of 0.05 wt% or more and 5 wt% or less (optimally, 1% to 2% wt%).
そして、これらの光触媒粒子と接着剤を、イオン交換水に溶解・分散し、全量３０Ｌ〜１００Ｌ用意する。その後、塗工直前にＰＶＡ架橋反応剤を、ＰＶＡ量に対し有効性分量５ｗｔ％となるように添加し、塗工液とする。 Then, the photocatalyst particles and the adhesive are dissolved and dispersed in ion-exchanged water to prepare a total volume of 30 L to 100 L. Then, immediately before coating, a PVA cross-linking reactant is added so as to have an effective amount of 5 wt% with respect to the amount of PVA to obtain a coating liquid.
チタンアパタイトの分散については特に手法は指定しないが、例えば日本スピンドル社製の粉体吸引連続溶解分散装置（商品名：ジェットペースタＪＰ−Ｓ）を用い、一次粒子の凝集を防止しながら分散・溶解するのが好ましい。
この塗工液を、ロール状原紙１，０００〜２５，０００ｍに対してダイレクトグラビア塗工装置を用い、湿潤重量１０ｇ／ｍ2以上となるように塗工する。
The method of dispersing titanium apatite is not particularly specified. For example, a powder suction continuous dissolution and dispersion device (trade name: Jet Paster JP-S) manufactured by Nippon Spindle Co., Ltd. is used to prevent dispersion of primary particles while preventing aggregation. Preferably, it is dissolved.
This coating liquid is applied to 1,000 to 25,000 m of rolled base paper using a direct gravure coating apparatus so as to have a wet weight of 10 g / m 2 or more.
ステップＳ１で形成する本実施形態の紙状体の紙は、「ＪＩＳ Ｃ２３００−２ 『電気用セルロース紙-第２部：試験方法』 ７．０Ａ 密度」のＢ法に規定された方法で絶乾状態のセパレータの密度を測定している。本実施形態の紙状体の紙は密度が０．３ｇ／ｍ3〜０．６５ｇ／ｍ3となっているので、セルロース繊維間の隙間から塗工液が表面側へと浸透するが、この浸透を助けるためにも、紙状体の裏面側から、塗工液を、塗布することとしている。しかし、裏面のみでなく、表面から塗布してもよい。 The paper-like paper of the present embodiment formed in step S1 is completely dried by the method specified in the method B of “JIS C2300-2“ Cellulose paper for electricity-Part 2: Test method ”7.0A density”. The density of the separator in the state is measured. Because paper paper-like body of the present embodiment has a density between 0.3g / m 3 ~0.65g / m 3 , but the coating liquid from the gap between the cellulose fibers from penetrating to the surface side, the In order to facilitate the penetration, a coating liquid is applied from the back side of the paper-like body. However, you may apply | coat from not only a back surface but a front surface.
次にステップＳ５の乾燥工程に移行し、塗工液の乾燥を行う。
具体的には、まず第一段階として、室温〜６０°Ｃで熱風乾燥することで、紙状体として水分含有量を３０％以下の半乾燥状態とする。
その後、第２段階として、前記第一段階の熱風乾燥温度よりも高い温度に表面温度（例えば１２０〜１６０°Ｃ）に加熱した加熱面（ヤンキードライヤー）に紙状体を接触させ、架橋反応を促進してチタンアパタイトを展着させる。
Next, the process proceeds to the drying step of step S5, and the coating liquid is dried.
Specifically, first, as a first step, the paper is dried in a hot air at room temperature to 60 ° C. to obtain a paper-like body in a semi-dry state with a water content of 30% or less.
Then, as a second stage, the paper-like body is brought into contact with a heating surface (Yankee dryer) heated to a surface temperature (for example, 120 to 160 ° C.) at a temperature higher than the hot air drying temperature in the first stage, and a crosslinking reaction is performed. Promotes and spreads titanium apatite.
このときＰＶＡは分子中の水酸基を中心とした脱水縮合反応を起こすことによって分子同士が化学結合しポリマー化する。
ポリマー化することにより紙状体としての強度増加、耐水性向上及びチタンアパタイトの紙への接着効果が発現する。この反応は不可逆的であるためこの工程後に水にさらされても再溶解してチタンアパタイトが脱落することはなくなる。つまり製造工程の後半に存在する撚糸で、水撚糸が可能な強度となるのに加え、紙撚糸とした場合十分な洗濯耐性を有する紙撚糸とすることが出来る。
At this time, the PVA undergoes a dehydration condensation reaction centering on a hydroxyl group in the molecule, whereby the molecules are chemically bonded to each other to be polymerized.
By polymerizing, an increase in strength as a paper-like body, an improvement in water resistance, and an effect of bonding titanium apatite to paper are exhibited. Since this reaction is irreversible, the titanium apatite does not fall off even if exposed to water after this step. In other words, the twisted yarn present in the latter half of the manufacturing process has a strength that enables water twisting, and in the case of a paper twisted yarn, a paper twisted yarn having sufficient washing resistance can be obtained.
次に、ステップＳ７の帯状紙形成工程に移行し、乾燥後の紙状体を巻き取り、この塗工紙を用いて紙撚糸とするためスリッターを用いて１〜１０ｍｍ幅で裁断し、帯状の紙材（紙テープ）とする。裁断幅は使用する糸の仕様によって様々であるが、アパレル用途の場合は例えば１．５ｍｍ、２．０ｍｍが最適である。 Next, the process proceeds to the band-shaped paper forming step of step S7, the dried paper-like body is wound up, cut into a width of 1 to 10 mm using a slitter to form a paper twist using this coated paper, and a band-shaped paper is formed. Paper (paper tape). The cutting width varies depending on the specification of the yarn to be used, but in the case of apparel use, for example, 1.5 mm and 2.0 mm are optimal.
次に、ステップＳ１０の紙材の撚り工程に移行し、裁断加工した帯状の紙材（紙テープ）を、立撚機あるいは並撚機のような撚糸機器を用いて撚糸して紙撚糸とする。撚糸は主に水撚糸を行なうことでアパレル用途として微細でキンクの無い高強度な糸とすることができる。水撚糸とは撚糸時に例えば水をつけて湿らせてから加工する手法を指す。ここで水につける方法に限定されるものではなく、紙状体に水を吹き付けて湿らせてもよい更に人水に限定されるものではなく、他の溶剤であっても良い。 Next, the process proceeds to the paper material twisting step of step S10, and the cut strip-shaped paper material (paper tape) is twisted using a twisting device such as a vertical twisting machine or a parallel twisting machine to form a paper twisted yarn. By mainly performing water twisting, twisted yarn can be made into a fine, high-strength kink-free yarn for apparel applications. Water twisting refers to a technique in which, for example, water is applied during the twisting to make it wet and then processed. Here, the method is not limited to the method of immersing in water, and water may be sprayed and moistened on the paper-like body. Further, the method is not limited to human water, and other solvents may be used.
図２、本実施形態の帯状の紙材の拡大断面図を示している。
図２に示すように本実施の形態においては、光触媒粒子（チタンアパタイト粒子）１が、糸状体の表面部おいて、セルロース繊維２の表面に、接着剤（ＰＶＡ）によって、接着された状態であり、ＰＶＡは光触媒粒子１とセルロース繊維２と一体となっているため観察のみで見える状態ではない。
FIG. 2 is an enlarged cross-sectional view of the belt-shaped paper material of the present embodiment.
As shown in FIG. 2, in the present embodiment, the photocatalyst particles (titanium apatite particles) 1 are adhered to the surface of the cellulose fibers 2 on the surface of the filament by an adhesive (PVA). Since PVA is integrated with the photocatalyst particles 1 and the cellulose fibers 2, it is not visible only by observation.
本実施形態の紙撚糸は、セルロース繊維２の集合体によって形成された糸状体と、この糸状体に接着剤（ＰＶＡ）で付着された複数の光触媒粒子（チタンアパタイト粒子）１とを備え、前記光触媒粒子（チタンアパタイト粒子）１は、前記糸状体の表面よりも、内部に多く設けたものであるので、長期的な光触媒効果が得られるようになる。 The paper twisted yarn of the present embodiment includes a filament formed by an aggregate of cellulose fibers 2 and a plurality of photocatalyst particles (titanium apatite particles) 1 attached to the filament with an adhesive (PVA). Since the photocatalyst particles (titanium apatite particles) 1 are provided more in the inside than the surface of the filament, a long-term photocatalytic effect can be obtained.
すなわち、本実施形態の紙撚糸は、糸状体に接着剤で複数の光触媒粒子を付着させるだけではなく、帯状の紙材（紙テープ）を、立撚機あるいは並撚機のような撚糸機器を用いて撚糸して紙撚糸としたものである。
つまり、光触媒粒子（チタンアパタイト粒子）１を付着させた帯状の紙材（紙テープ）を、撚糸工程により、何度も折りたたんでいく状態となるので、表面や裏面の光触媒粒子（チタンアパタイト粒子）１も、紙撚糸の内部に折りたたまれた状態となる。
That is, the paper twisted yarn of the present embodiment not only attaches a plurality of photocatalyst particles to the thread-like body with an adhesive, but also uses a belt-shaped paper material (paper tape) with a twisting device such as a vertical twisting machine or a parallel twisting machine. And twisted into a paper twisted yarn.
In other words, the belt-shaped paper material (paper tape) to which the photocatalyst particles (titanium apatite particles) 1 are attached is folded many times by the twisting process. Is also folded inside the paper twisted yarn.
その結果、本実施形態の紙撚糸においては、光触媒粒子（チタンアパタイト粒子）１が、糸状体の表面よりも、内部に多く含まれる状態となり、これにより、糸状体に、他のものがこすれたり、あるいは洗濯したりしても、糸状体内部に多く含まれている光触媒粒子（チタンアパタイト粒子）１が脱落することは極めて少なく、糸状体は長期的に、大量の光触媒粒子（チタンアパタイト粒子）１を保持した状態となる。 As a result, in the paper twisted yarn of the present embodiment, the photocatalyst particles (titanium apatite particles) 1 are contained more in the filament than in the surface of the filament, thereby rubbing the filament with another material. Even when washing or washing, the photocatalyst particles (titanium apatite particles) 1 contained in a large amount in the filaments are extremely unlikely to fall off. 1 is held.
また、紫外線の糸状体内部への浸透性は高いので、糸状体の内部に多く保持された光触媒粒子（チタンアパタイト粒子）１による光触媒効果が長期的に発揮されることになる。
そして、この様にして製造された紙撚糸は、ステップＳ１２の織り工程において例えば横糸として用いられ、縦糸と共に織物に仕上げられる。
In addition, since the penetration of the ultraviolet rays into the filament is high, the photocatalytic effect of the photocatalyst particles (titanium apatite particles) 1 held in the filament in a large amount is exhibited for a long time.
The twisted paper yarn thus manufactured is used as, for example, a weft yarn in the weaving process in step S12, and is finished into a woven fabric together with the warp yarn.
また、帯状の紙材として、密度が０．３ｇ／ｍ3〜０．６５ｇ／ｍ3としているので、糸としての風合いが良く、しかも強度も維持できるものとなる。
なお、上記実施形態では、製造方法として、セルロース繊維を用いた抄紙法により紙状体を形成することも説明したが、紙状体を、他社から購入する場合には、自社においての
Further, as the belt-like paper material, the density is set to 0.3g / m 3 ~0.65g / m 3 , good texture as yarn, yet becomes the strength can be maintained.
In the above-described embodiment, as a manufacturing method, a paper-like body is formed by a paper-making method using cellulose fibers. However, when a paper-like body is purchased from another company, the paper-like body is formed in-house.
抄紙工程は不要となる。
このようにして製造した紙撚糸を少なくとも横糸として用いているため、光触媒粒子（チタンアパタイト粒子）１は織物の内部に多く配設・保持された状態に維持できるため、長期的な光触媒効果が得られる。
The papermaking process is not required.
Since the paper twist yarn thus manufactured is used at least as the weft yarn, the photocatalyst particles (titanium apatite particles) 1 can be maintained in a state of being disposed and held in a large amount in the woven fabric, and a long-term photocatalytic effect can be obtained. Can be
