Description

コンポジット麻布及びコンポジット麻布の生産方法Composite linen and production method of composite linen

 本発明は、コンポジット麻布及びコンポジット麻布の生産方法に関する。 The present invention relates to composite linen and a method for producing composite linen.

 麻布は、天然繊維によって作られた布の中でも抜群に吸水性が高い。例えば、麻には、綿の4倍の吸水性がある(例えば非特許文献1参照)。さらに、麻は、高い吸水性により、水に濡れると引張り強度が約50%又はそれ以上に増加する特徴がある。 Azabu has outstandingly high water absorption among cloths made of natural fibers. For example, hemp has four times the water absorption of cotton (see, for example, Non-Patent Document 1). Furthermore, hemp is characterized by its high water absorption, which increases its tensile strength by about 50% or more when it gets wet with water.

 また、麻の繊維の引張り強度は、綿の約2倍であり、羊毛の約4倍であるため、丈夫で長持ちである。そして、麻布は、伸びにくく、テキスタイル(textile)として型崩れを起こしにくいが、皺になりやすいという特徴がある。 In addition, the tensile strength of hemp fiber is about twice that of cotton and about four times that of wool, so it is durable and long-lasting. Azabu is hard to stretch and does not easily lose its shape as a textile, but it is prone to wrinkles.

 しかしながら、従来の麻布は、天然繊維の織物としては強度が強くても、工業用途に利用する素材としては強度が十分でない場合があった。また、従来の麻布は、酸化などによって劣化が生じてしまい、強度を保つことが困難であるという問題があった。 However, the conventional linen cloth may have high strength as a natural fiber woven fabric, but may not have sufficient strength as a material used for industrial purposes. Further, the conventional linen cloth has a problem that it is difficult to maintain its strength because it deteriorates due to oxidation or the like.

It is characterized by including a layer forming step of impregnating the linen cloth with the urethane film to form an integrated composite layer.

 以下に、一実施形態にかかるコンポジット麻布について図面を用いて説明する。なお、ここでは「麻布」と「他の部材」とを組み合わせて、「麻布」単独、又は「他の部材」単独では得られない特性を有する部分を少なくとも一部に備えるものをコンポジット麻布と称することとする。 The composite linen cloth according to the embodiment will be described below with reference to the drawings. Here, a combination of "Azabu" and "other members" and having at least a part having characteristics that cannot be obtained by "Azabu" alone or "other members" alone is referred to as composite linen cloth. I will do it.

 図1は、一実施形態にかかるコンポジット麻布、及びコンポジット麻布を生産する方法を模式的に示す図である。図1に示すように、コンポジット麻布を生産する場合、麻布1に対して、まず、表面側及び裏面側から例えばエステル(ester)系のウレタンフィルム(urethane film)2で挟み込む。 FIG. 1 is a diagram schematically showing a composite linen cloth according to an embodiment and a method for producing the composite linen cloth. As shown in FIG. 1, when producing a composite linen cloth, first, the linen cloth 1 is sandwiched between the front side and the back side with, for example, an ester-based urethane film 2.

 そして、ウレタンフィルム2で挟み込まれた麻布1に対して、例えば図示しないオートクレーブによって熱と圧力とを加えることにより、麻布1にウレタンフィルム2を含侵させて一体にされたコンポジット層(コンポジット材)を形成する。ここでは、このコンポジット層がコンポジット麻布3となる。 Then, by applying heat and pressure to the linen cloth 1 sandwiched between the urethane film 2 by, for example, an autoclave (not shown), the linen cloth 1 is impregnated with the urethane film 2 to be integrated into a composite layer (composite material). To form. Here, this composite layer is the composite linen cloth 3.

 オートクレーブは、ウレタンフィルム2で挟み込まれた麻布1に対して、例えば140°Cで0.5Mpaの圧力を加え、例えばコンポジット麻布3がシート状のソフトコンポジット麻布になるように成形する。 In the autoclave, a pressure of 0.5 MPa is applied to the linen 1 sandwiched between the urethane films 2 at, for example, 140 ° C, and the composite linen 3 is formed into a sheet-shaped soft composite linen.

 コンポジット麻布3は、麻布1が水に濡れた場合と同様又はそれ以上に、引張り強度が例えば40%~300%程度増加している。 In the composite linen cloth 3, the tensile strength is increased by, for example, about 40% to 300%, as in the case where the linen cloth 1 is wet with water or more.

 麻布1の素材である麻糸は、植物表皮の内側にある柔繊維、又は葉茎などから採取された繊維から作られており、不均一な微細繊維を含む吸水性が高い天然素材である。このため、麻布1にはウレタンフィルム2が十分に含侵し、麻糸の繊維の中までウレタンが絡むので、麻布1の繊維と樹脂(ウレタン)が一体化したコンポジット層(コンポジット材)が形成される。 The linen thread, which is the material of linen cloth 1, is made of soft fibers inside the epidermis of plants or fibers collected from leaf stems, etc., and is a natural material with high water absorption containing non-uniform fine fibers. Therefore, the urethane film 2 sufficiently impregnates the linen cloth 1, and the urethane is entangled in the fibers of the linen thread, so that a composite layer (composite material) in which the fibers of the linen cloth 1 and the resin (urethane) are integrated is formed. ..

 すなわち、コンポジット麻布3は、麻の繊維と樹脂(ウレタン)とを剥離することが困難になる。また、コンポジット麻布3は、ウレタンフィルム2で挟み込まれる前の麻布1と同等の厚さや、麻布1よりも薄く成形することも可能である。例えば、コンポジット麻布3において、麻布1が占める体積の割合は50%以上である。 That is, in the composite linen cloth 3, it becomes difficult to peel off the linen fiber and the resin (urethane). Further, the composite linen cloth 3 can be formed to have the same thickness as the linen cloth 1 before being sandwiched between the urethane films 2 and to be thinner than the linen cloth 1. For example, in the composite linen cloth 3, the volume ratio occupied by the linen cloth 1 is 50% or more.

 比較例として、エポキシ樹脂やフェノール樹脂などにガラス繊維や炭素繊維などの繊維を複合して強度を向上させた繊維強化プラスチック(FRP)などは、繊維に対して樹脂が十分に入り込めないために繊維と樹脂とが一体になれず、剥がれやすいという欠点がある。 As a comparative example, fiber reinforced plastic (FRP), which is made by combining fibers such as glass fiber and carbon fiber with epoxy resin or phenol resin to improve the strength, is because the resin cannot sufficiently penetrate into the fiber. There is a drawback that the fiber and the resin cannot be integrated and are easily peeled off.

 なお、麻布1は、生成り(キナリ)であってもよいし、染め又は漂白などの処理をされていてもよいし、予め熱的に安定させた複合材料(TSC:Thermally Stable Composite)などであってもよい。 The linen cloth 1 may be produced (kinari), may have been dyed or bleached, or may be made of a pre-thermally stabilized composite material (TSC: Thermally Stable Composite) or the like. There may be.

 また、麻布1は、1cm当たりに並ぶ麻糸の本数が例えば10本以上であることが望ましい。また、麻布1は、例えば平織又は鹿の子織である。ただし、麻布1を構成する麻糸、及び麻布1の織の種類等は、これらに限定されない。 Further, it is desirable that the number of hemp threads lined up per 1 cm of the linen cloth 1 is, for example, 10 or more. Further, the linen cloth 1 is, for example, a plain weave or a fawn weave. However, the linen thread constituting the linen cloth 1 and the type of weaving of the linen cloth 1 are not limited to these.

 図2は、一実施形態にかかるコンポジット麻布3を生産する方法を例示するフローチャートである。図2に示すように、コンポジット麻布3を生産する場合、まず、麻布1に対し、表面側及び裏面側からウレタンフィルム2で挟み込む(S100:挟込工程)。 FIG. 2 is a flowchart illustrating a method of producing the composite linen cloth 3 according to the embodiment. As shown in FIG. 2, when producing the composite linen cloth 3, first, the linen cloth 1 is sandwiched between the urethane film 2 from the front surface side and the back surface side (S100: sandwiching step).

 次に、ウレタンフィルム2で挟み込まれた麻布1に対して熱と圧力とを加えることにより、麻布1にウレタンフィルム2を含侵させて一体にされたコンポジット層を形成する(S102:層形成工程)。 Next, by applying heat and pressure to the linen cloth 1 sandwiched between the urethane films 2, the linen cloth 1 is impregnated with the urethane film 2 to form an integrated composite layer (S102: layer forming step). ).

 このようにして、麻布1にウレタンフィルム2を含侵させて一体にされたコンポジット層を形成することにより、例えばシート状のコンポジット麻布3を生産することができる。 In this way, by impregnating the linen 1 with the urethane film 2 to form an integrated composite layer, for example, a sheet-shaped composite linen 3 can be produced.

 図3は、一実施形態にかかるコンポジット麻布3の外観を例示する写真である。コンポジット麻布3は、麻布1よりも引張り強度が向上し、酸化等による劣化も防止されている。また、コンポジット麻布3は、麻布のデメリットであった皺ができず、撥水性もある。 FIG. 3 is a photograph illustrating the appearance of the composite linen cloth 3 according to the embodiment. The composite linen cloth 3 has higher tensile strength than the linen cloth 1, and deterioration due to oxidation or the like is prevented. Further, the composite linen cloth 3 does not have wrinkles, which is a demerit of linen cloth, and has water repellency.

 また、コンポジット麻布3は、ウレタンフィルム2を所定の透明度に設定すれば、麻布1の風合いを残すことも可能であり、アルコールなどの液体で消毒することも可能である。 Further, the composite linen cloth 3 can retain the texture of the linen cloth 1 by setting the urethane film 2 to a predetermined transparency, and can be disinfected with a liquid such as alcohol.

 つまり、コンポジット麻布3は、設計値に応じて強度を調整したり、サイズ、形状を任意に設定することが可能になっており、麻布1単独、又はウレタンフィルム2単独では得られない特性を備えているため、容易に多方面の工業用途へ適用することが可能である。 That is, the composite linen 3 can be adjusted in strength according to the design value, and the size and shape can be arbitrarily set, and has characteristics that cannot be obtained by the linen 1 alone or the urethane film 2 alone. Therefore, it can be easily applied to various industrial applications.

 次に、コンポジット麻布3の具体例について説明する。図4は、コンポジット麻布3の具体例に用いられる複数の麻布1の具体例を示す図である。コンポジット麻布3は、例えば図4に示した麻布(a)~(e)などに相当する麻布1を用いて構成される。 Next, a specific example of the composite linen cloth 3 will be described. FIG. 4 is a diagram showing a specific example of a plurality of linen cloths 1 used in the specific example of the composite linen cloth 3. The composite linen cloth 3 is configured by using the linen cloth 1 corresponding to the linen cloths (a) to (e) shown in FIG. 4, for example.

 麻布(a)は、染めのない平織の麻布であり、生地の厚さが0.31mm、麻糸の太さが麻番手40/1、1cm当たりの麻糸の本数が26となっている。 The linen cloth (a) is a plain weave linen cloth without dyeing, the thickness of the cloth is 0.31 mm, the thickness of the linen thread is 40/1, and the number of linen threads per 1 cm is 26.

 麻布(b)は、染めが有る平織の麻布であり、生地の厚さが0.16mm、麻糸の太さが麻番手12/1、1cm当たりの麻糸の本数が30となっている。 The linen cloth (b) is a dyed plain weave linen cloth, the thickness of the cloth is 0.16 mm, the thickness of the linen thread is 12/1, and the number of linen threads per 1 cm is 30.

 麻布(c)は、染めが有る平織の麻布であり、生地の厚さが0.28mm、麻糸の太さが麻番手40/1、1cm当たりの麻糸の本数が20となっている。 The linen cloth (c) is a dyed plain weave linen cloth, the thickness of the cloth is 0.28 mm, the thickness of the linen thread is 40/1, and the number of linen threads per 1 cm is 20.

 麻布(d)は、染めが有る平織の麻布であり、生地の厚さが0.33mm、麻糸の太さが麻番手40/1、1cm当たりの麻糸の本数が10となっている。 The linen cloth (d) is a plain weave linen cloth with dyeing, the thickness of the cloth is 0.33 mm, the thickness of the linen thread is 40/1, and the number of linen threads per 1 cm is 10.

 麻布(e)は、染めが有る鹿の子織(裏鹿の子)の麻布であり、生地の厚さが0.38mm、麻糸の太さが麻番手80/1となっている。 The linen cloth (e) is a dyed linen cloth of Kanoko weave (back Kanoko), and the thickness of the cloth is 0.38 mm and the thickness of the linen thread is 80/1.

 図5は、図4に示した麻布(a)~(e)に対して、引張荷重及び伸びを測定するために作成された試験片を示す写真である。麻布(a)~(e)の試験片は、コンポジット麻布3に対する比較例の試験片として用いられた。麻布(a)~(e)の試験片は、例えば幅30mm、長さ300mmに成形されている。 FIG. 5 is a photograph showing test pieces prepared for measuring tensile load and elongation with respect to the linen cloths (a) to (e) shown in FIG. The test pieces of linen (a) to (e) were used as test pieces of a comparative example with respect to composite linen 3. The test pieces of linen cloths (a) to (e) are formed into, for example, a width of 30 mm and a length of 300 mm.

 また、麻布(a)~(e)を用いて構成されたコンポジット麻布3は、それぞれ幅30mm、長さ300mmに成形された実施例の試験片として用いられた。なお、実施例の試験片は、麻布(a)~(e)がそれぞれウレタンフィルム2(FOR-MPシーダム社)で挟み込まれ、例えばオートクレーブによって140度に加熱され、0.5Mpaの圧力がかけられて90分保持された後、減圧されて温度が80度に下げられる条件で作成されている。 Further, the composite linen cloth 3 constructed by using the linen cloths (a) to (e) was used as a test piece of an example molded into a width of 30 mm and a length of 300 mm, respectively.
