【発明を実施するための最良の形態】
【００１７】
以下、この発明になる連続皮革糸およびこれを用いた皮革糸織物について、図面に示す具体的な実施例にもとづいて詳細に説明する。図１は、この発明になる連続皮革糸の製造手順を図示するものであって、図１Ａは、天然皮革製の原シートを示す概略的な平面図、図１Ｂは、人工皮革製または合成皮革製の原シートを示す概略的な平面図、図１Ｃは、以後の加工がし易いような大きさ（ｗ×Ｌ）に裁断した裁断片を示す概略的な斜視図、図１Ｄは、この裁断片を長さ方向に連続的に繋いだ裁断片繋ぎ連続体を示す概略的な斜視図、図１Ｄ１は、繋ぎ部分を拡大して示す概略的な断面図、図１Ｅは、当該裁断片繋ぎ連続体をプレス圧縮して厚さ寸法をｔｏとした概略的な斜視図、図１Ｆは、これをスリットして、この発明になる連続皮革糸の形態を示す概略的な斜視図である。図２は、この発明になる連続皮革糸の製造手順を説明するためのフローチャート図である。
【００１８】
図１および図２に基づいて、この発明になる連続皮革糸の製造手順について詳細に説明する。まず、図１Ａに示すような天然皮革製の原シート１の場合には、なめし加工２１される段階において、その皮革自体にフッ素あるいはシリコンなどの撥水・撥油（防汚性）の溶剤を用いて処理したすることにより、なめし加工され乾燥された皮革は、天然の風合いを損なわない防汚性の皮革となる。このなめし皮革を、希望の厚さ寸法ｔに漉き加工２２する。この発明において、天然皮革としては、牛、山羊、羊、鹿、クロコ、カンガルー、オーストリッチなどの全てに対して有効であり、且つ、染色についても自由である。
【００１９】
図１Ｂに示すような人工皮革製または合成皮革製の原シート１１は、例えば、ポリエステルやナイロンなどの基布に対し、その表面にポリウレタンをコーティングした構成のものが大半であり、このような構成のものについては、上記するなめし加工２１並びに漉き加工２２は省略され、実質的に、原シート１１の段階で厚さ寸法ｔのものとして加工され準備される。
【００２０】
この発明では、なめし加工２１並びに漉き加工２２された天然皮革製の原シート１、および人工皮革製または合成皮革製の原シート１１は、その後の加工が行い易いような大きさ（幅寸法ｗ、長さ寸法Ｌ）の裁断片２に裁断加工２３され（図１Ｃ参照）、次ぎの繋ぎ加工２４において、長さ方向に繋ぎ合わされて裁断片繋ぎ連続体３に形成される（図１Ｄ参照）。前記裁断片２を長さ方向に繋ぎ合わせる場合、裁断片２の長さ方向の端部をそれぞれ傾斜状のカット面４ａ、４ｂとして形成しておき、該カット面４ａ、４ｂを重ね合わせ状にして、適当な接着剤あるいは融着の手段により繋ぎ合わせる（図１Ｄ１参照）。
【００２１】
このようにして繋ぎ合わされた裁断片繋ぎ連続体３は、プレス加工２５によってプレス圧縮され、約０．１〜１程度の厚さ寸法ｔｏに加工され、圧縮連続体５として形成される（図１Ｅ参照）。このプレス加工２５では、そのプレス圧縮により、皮革の内部構造における分子間の結合を密にして、引張り強度を上げる。これに加えて、図２に示すような裏面フィルム加工２６により、裏面に特殊樹脂または塗料などを分子間結合またはナノテクノロジーの技術を用いて施すこともできる。この段階で、前記圧縮連続体５の表面および／または裏面に、表面仕上げ処理層を設けて、帯状に仕上がる連続皮革糸６の表面および裏面の装飾性を向上させることもできる。
【００２２】
前記圧縮連続体５は、スリット加工２７において、幅寸法ｗｏにスリットされ帯状の連続皮革糸６に仕上げられる。この幅寸法ｗｏは、前記連続皮革糸６の使用目的に応じて、約１ｍｍ〜８ｍｍ程度のものである。この連続皮革糸６の長さ寸法は、必要に応じて適宜設定することができ、例えば、最長３０ｍのものにすることができる。
【００２３】
次に、上記する加工手順に従って帯状に仕上げられた連続皮革糸６を用いた皮革糸織物の具体的な実施例について、図３〜図５に基づいて説明する。図３は、この発明になる連続皮革糸を用いて製織される皮革糸織物であって、その第１の実施例を示す概略的な斜視図、図４ＡおよびＢは、その第２および第３の実施例を示す概略的な斜視図、図５Ａ、ＢおよびＣは、その第４〜第６の実施例を示す概略的な斜視図である。
【００２４】
まず、図３に示す第１の実施例になる皮革糸織物３１は、緯糸として連続皮革糸６を用いたものであり、当該連続皮革糸６を緯糸として地経糸４１に織り込んだものである。この場合、連続皮革糸６は、既存の織機におけるシャトルにより幅方向の両端側から交互に連続的に緯糸として織り込まれる。具体的には、前記連続皮革糸６は、織機におけるシャトルに通常の繊維糸と同様にセットされ、その際、意識的に撚りながらセットしておけば、経糸４１に絡む場合に、その撚りがランダムに当該連続皮革糸６の表、裏を関係なく回転しながら織り込むため、緯糸が表裏反転部５１を形成して経糸で固定されるので、紡ぎのようなゆらぎを感じさせる織物を仕上げられる。この場合、織物３１の織幅Ｗについて、何らの制限もない。
【００２５】
図４Ａおよび図４Ｂに示す第２および第３の実施例になる皮革糸織物３２、３３は、経糸として連続皮革糸６を用いたものであり、当該連続皮革糸６を経糸として地緯糸４２、４３に織り込んだものである。この場合、前記経糸としての連続皮革糸６は、図４Ａに示す第２の実施例のもののように、その織長さ方向に沿って並行に配列したものであってもよいし、あるいは、図４Ｂに示す第３の実施例のもののように、その織長さ方向の間で表裏が反転する表裏反転部５１を形成するものであってもよい。
【００２６】
図５Ａ、図５Ｂおよび図４Ｃに示す第４、第５および第６の実施例になる皮革糸織物３４、３５、３６は、前記連続皮革糸６を経糸および緯糸の双方に織り込んだ構成例を示すものである。この場合、経糸および緯糸に織り込まれる連続皮革糸６は、図５Ａに示す第４の実施例のもののように、その緯糸側についてのみ、その織幅方向の間で表裏が反転する表裏反転部５１を形成するものであってもよいし、図５Ｂに示す第５の実施例のもののように、その経糸側についてのみ、その織長さ方向の間で表裏が反転する表裏反転部５１を形成するものであってもよいし、あるいは、図５Ｃに示す第６の実施例のもののように、その経糸側および緯糸側の双方に、表裏が反転する表裏反転部５１を形成するものであってもよい。これらの皮革糸織物３１〜３６は、いずれも、従来の皮革織物にはない、全く特異な表面紋様を形成するものであり、極めて斬新なものといえる。
【産業上の利用可能性】
【００２７】
以上の構成において、この発明になる連続皮革糸によれば、皮革シート材から所望の大きさの裁断片を形成し、この裁断片をその長さ方向に繋ぎ合わせて裁断片繋ぎ連続体とし、この裁断片繋ぎ連続体をプレス圧縮した後、最終の糸の幅寸法に対応する幅にスリットして連続皮革糸としたものであり、例えば、天然皮革のように、その大きさ（サイズ）に限界があるものの場合、これをスリットして皮革糸を得たとしても、その長さ寸法が限定的なものであるため、これを用いて織物を製織する際、その大きさに限界を意識したデザイン並びに意匠にせざるをえない。この点、この発明になる上記連続皮革糸によれば、当該連続皮革糸を織物に用いた場合、これを織幅方向の両端側から交互に連続的に緯糸を織り込むこと、並びに織長さ方向に連続する経糸として織り込むこと、などが一挙に可能であり、それによって極めて斬新な皮革糸織物を提供することができるなどという点において極めて有効に作用するものといえる。【Technical field】

FIG. 2 is a flowchart for explaining the procedure for producing the continuous leather yarn according to the present invention.
[0018]
Based on FIG. 1 and FIG. 2, the manufacturing procedure of the continuous leather yarn which becomes this invention is demonstrated in detail. First, in the case of an original sheet 1 made of natural leather as shown in FIG. 1A, at the stage of tanning 21, a water or oil repellent (antifouling) solvent such as fluorine or silicon is applied to the leather itself. By using and processing, the tanned and dried leather becomes an antifouling leather that does not impair the natural texture. This tanned leather is chopped 22 to a desired thickness t. In the present invention, the natural leather is effective for all of cows, goats, sheep, deer, crocodile, kangaroos, ostrich and the like, and is free to dye.
[0019]
The raw sheet 11 made of artificial leather or synthetic leather as shown in FIG. 1B is mostly composed of a base fabric such as polyester or nylon and coated with polyurethane on the surface thereof. As for the sheet, the tanning process 21 and the squeezing process 22 described above are omitted, and are substantially processed and prepared as having the thickness t at the stage of the original sheet 11.
[0020]
In the present invention, the natural leather original sheet 1 subjected to the tanning process 21 and the tanning process 22, and the raw sheet 11 made of artificial leather or synthetic leather are sized so as to be easily processed (width dimension w, The cut piece 23 of the length dimension L) is cut (see FIG. 1C), and in the next joining process 24, it is joined in the length direction to form the cut piece connecting continuous body 3 (see FIG. 1D). When joining the cut pieces 2 in the length direction, the end portions in the length direction of the cut pieces 2 are formed as inclined cut surfaces 4a and 4b, respectively, and the cut surfaces 4a and 4b are overlapped. Then, they are joined together by an appropriate adhesive or fusion means (see FIG. 1D1).
[0021]
The piece-jointed continuous body 3 joined in this way is press-compressed by a press process 25 and processed into a thickness dimension to about 0.1 to 1 to form a compressed continuous body 5 (FIG. 1E). reference). In this press work 25, the press compression compresses the bonds between molecules in the internal structure of the leather to increase the tensile strength. In addition, special resin or paint can be applied to the back surface using intermolecular bonding or nanotechnology techniques by back film processing 26 as shown in FIG. At this stage, a surface finishing treatment layer can be provided on the surface and / or back surface of the compressed continuous body 5 to improve the decorativeness of the surface and back surface of the continuous leather yarn 6 finished in a strip shape.
[0022]
The compressed continuous body 5 is slit to a width dimension wo and finished into a strip-shaped continuous leather yarn 6 in the slit processing 27. The width wo is about 1 mm to 8 mm depending on the purpose of use of the continuous leather yarn 6. The length dimension of the continuous leather thread 6 can be appropriately set as necessary, and can be, for example, a maximum of 30 m.
[0023]
Next, specific examples of the leather yarn woven fabric using the continuous leather yarn 6 finished in a belt shape according to the above-described processing procedure will be described with reference to FIGS. FIG. 3 is a leather yarn fabric woven using the continuous leather yarn according to the present invention, and is a schematic perspective view showing a first embodiment thereof. FIGS. 4A and B are second and third views. FIGS. 5A, 5B and 5C are schematic perspective views showing the fourth to sixth embodiments.
[0024]
First, the leather yarn fabric 31 according to the first embodiment shown in FIG. 3 uses a continuous leather yarn 6 as a weft, and the continuous leather yarn 6 is woven into a ground warp yarn 41 as a weft. In this case, the continuous leather yarn 6 is woven continuously and alternately as weft yarn from both ends in the width direction by a shuttle in an existing loom. Specifically, the continuous leather yarn 6 is set on a shuttle in a loom in the same manner as a normal fiber yarn. At that time, if the yarn is entangled with the warp 41, the twist is not twisted. Since weaving is carried out while rotating the front and back of the continuous leather yarn 6 regardless of the surface, the weft yarn forms the front and back inversion portions 51 and is fixed by warp yarn, so that a fabric that feels fluctuations such as spinning can be finished. In this case, there is no restriction on the woven width W of the fabric 31.
[0025]
The leather yarn fabrics 32 and 33 according to the second and third embodiments shown in FIGS. 4A and 4B are obtained by using the continuous leather yarn 6 as the warp, and the weft yarn 42 using the continuous leather yarn 6 as the warp, 43. In this case, the continuous leather yarn 6 as the warp may be arranged in parallel along the woven length direction as in the second embodiment shown in FIG. 4A. Like the thing of the 3rd Example shown to 4B, you may form the front and back inversion part 51 which the front and back inverts between the woven length directions.
[0026]
The leather yarn fabrics 34, 35, and 36 shown in FIGS. 5A, 5B, and 4C in the fourth, fifth, and sixth embodiments are examples in which the continuous leather yarn 6 is woven into both warp and weft. It is shown. In this case, the continuous leather yarn 6 woven into the warp and the weft, as in the fourth embodiment shown in FIG. 5A, is the front / back reversing portion 51 where the front and back are reversed between the weft width direction only on the weft side. The front / back reversing portion 51 that reverses the front and back between the weaving length directions is formed only on the warp side, as in the fifth embodiment shown in FIG. 5B. Alternatively, as in the sixth embodiment shown in FIG. 5C, the front and back inversion portions 51 that invert the front and back sides may be formed on both the warp side and the weft side. Good. These leather yarn fabrics 31 to 36 all form a unique surface pattern that is not found in conventional leather fabrics, and can be said to be extremely novel.
[Industrial applicability]
[0027]
In the above configuration, according to the continuous leather yarn according to the present invention, a cut piece of a desired size is formed from the leather sheet material, and the cut piece is joined in the length direction to form a cut piece continuous continuous body. After this compressed and continuous piece is pressed and compressed, it is slit into a width corresponding to the width of the final yarn to form a continuous leather thread. For example, like natural leather, its size (size) Even if there is a limit, even when slitting it to obtain leather yarn, the length dimension is limited, so when weaving the fabric using this, we were aware of the limit on the size It must be a design and design. In this regard, according to the continuous leather yarn according to the present invention, when the continuous leather yarn is used in a woven fabric, the weft yarn is alternately woven continuously from both ends in the woven width direction, and the woven length direction. It can be said that it can be woven as continuous warp yarns at once, and this can work extremely effectively in that it can provide a very novel leather yarn fabric.
