Description
本発明は、紙撚糸を使用した加工撚糸の製造方法、及び、該製造方法により製造された加工撚糸を製編織する織編物の製造方法に関するものである。 The present invention relates to a method for producing a textured twisted yarn using paper twisted yarn, and a method for producing a woven or knitted fabric by knitting and weaving the textured twisted yarn produced by the production method.
紙を細い幅にカットした紙テープに撚りをかけた紙撚糸、及び、紙撚糸を製編織した織編物が周知である。紙は、吸水性・吸湿性に優れる、放湿性が高く乾燥させやすい、独特のドライな肌触りを有するなどの利点を有している。 Twisted paper yarn obtained by twisting a paper tape obtained by cutting paper into narrow widths, and woven and knitted fabric obtained by knitting and weaving the twisted paper yarn are well known. Paper has advantages such as excellent water absorption and hygroscopicity, high moisture release and easy drying, and a unique dry touch.
一方、紙撚糸は引張り強度や引裂き強度が低い、伸縮性が乏しいために製編織しにくいという難点を有している。そこで、従前より、紙とは異なる素材の繊維を紙テープまたは紙撚糸と撚り合わせることにより、紙撚糸の難点を改善する試みがなされている（例えば、特許文献１参照）。 On the other hand, paper twisted yarn has drawbacks such as low tensile strength and tear strength, and poor stretchability, making it difficult to knit and weave. Therefore, attempts have been made to improve the drawbacks of paper twisted yarn by twisting fibers of a material different from paper with a paper tape or paper twisted yarn (see, for example, Patent Document 1).
しかしながら、紙とは異なる素材の繊維を紙テープまたは紙撚糸と撚り合わせた撚糸では、紙とは異なる素材の繊維が表面に表れる。吸水性・吸湿性や放湿性、ドライな肌触りという上記の利点は、主に撚糸の表面における特性によるものである。そのため、従来の試みでは、紙撚糸の難点を改善するべく使用した異素材の繊維によって、紙の利点が損なわれることがあった。 However, in a twisted yarn obtained by twisting a fiber of a material different from paper with a paper tape or a twisted paper yarn, the fiber of a material different from paper appears on the surface. The above advantages of water absorption, moisture absorption, moisture release, and dry touch are mainly due to the properties of the surface of the twisted yarn. Therefore, in previous attempts, the advantages of paper were sometimes compromised by the foreign fibers used to remedy the drawbacks of paper twist.
そこで、本発明は、上記の実情に鑑み、紙とは異なる素材の繊維によって紙撚糸の難点を改善することができると共に、紙の利点を損なうことがない加工撚糸の製造方法、及び、該製造方法により製造された加工撚糸を使用した織編物の製造方法の提供を、課題とするものである。 Therefore, in view of the above-mentioned circumstances, the present invention provides a method for producing a textured twisted yarn that can improve the drawbacks of paper twisted yarn by using fibers of a material different from paper and does not impair the advantages of paper, and the production method. An object of the present invention is to provide a method for producing a woven or knitted fabric using the textured twisted yarn produced by the method.
上記の課題を解決するため、本発明にかかる加工撚糸の製造方法は、
「紙テープに撚りをかけた紙撚糸に、紙とは異なる素材の繊維の糸である異素材糸の少なくとも一種を添え、前記紙撚糸の撚りの方向とは逆方向に撚る逆撚りを行うことにより加工撚糸を得るものであり、
単位長さの前記紙テープがＮ回撚られることによって長さＬの前記紙撚糸となるとき、
前記逆撚りは、前記紙撚糸の長さＬ当たりにＮの１．０倍を超えると共にＮの３．０倍以下の回数の撚りをかける」ものである。
In order to solve the above problems, the method for producing a textured twisted yarn according to the present invention includes:
"A paper twisted yarn obtained by twisting a paper tape is attached with at least one type of yarn of a different material, which is a yarn of a fiber material different from paper, and twisted in the opposite direction to the twisting direction of the paper twisted yarn. A processed twisted yarn is obtained by
When the paper tape of unit length is twisted N times to form the paper twisted yarn of length L,
The counter-twisting is performed by twisting the paper twist yarn more than 1.0 times N and not more than 3.0 times N per length L of the paper twist yarn.
以下では、紙テープを紙撚糸とするときの撚りを「元撚り」と称する。 Hereinafter, the twisting when the paper tape is used as the paper twisted yarn is referred to as "primary twisting".
本構成では、紙撚糸に異素材糸を添えた状態で、元撚りとは逆方向に撚って加工撚糸を得る。逆撚りの回数は、単位長さの紙テープがＮ回撚られることによって長さＬの紙撚糸となるとき、紙撚糸の長さＬ当たりＮの１．０倍を超える回数とする。つまり、紙撚糸は、撚り数ゼロの状態を超えて、更に元撚りとは逆方向に撚られる。元撚りされた紙撚糸に添えられた状態から紙撚糸と共に撚られる異素材糸は、紙撚糸が撚り数ゼロとなって元の紙テープ状に戻り、更にその状態を超えて逆方向に撚られるとき、紙テープの内側に巻き込まれるように撚り合わされる。従って、逆撚り後の加工撚糸の表面には異素材糸が表れにくい。そのため、紙の有する利点が損なわれるおそれが大幅に低減された加工撚糸を、製造することができる。そして、異素材糸の有する特性によって、本来の紙に乏しい特性を付与することができるため、紙撚糸の難点が改善された加工撚糸とすることができる。 In this configuration, the textured twisted yarn is obtained by twisting the paper twisted yarn with the different material yarn attached thereto in the opposite direction to the original twist. The number of reverse twists is set to exceed 1.0 times N per length L of the paper twisted yarn when a paper tape of unit length is twisted N times to form a paper twisted yarn of length L. That is, the paper twisted yarn is twisted in the direction opposite to the original twist beyond the state of zero twists. A different material thread that is attached to the original twisted paper yarn and twisted together with the paper yarn returns to the original paper tape shape when the number of twists of the paper yarn becomes zero, and is further twisted in the opposite direction beyond that state. , are twisted together to be wrapped inside the paper tape. Therefore, the yarn of a different material is less likely to appear on the surface of the textured twisted yarn after reverse twisting. Therefore, it is possible to produce a textured twisted yarn in which the possibility of losing the advantages of paper is greatly reduced. Further, the properties of the yarn of different material can impart properties that are inherently lacking in paper, so that a textured twisted yarn can be obtained in which the drawbacks of the paper twisted yarn are improved.
なお、単位長さの紙テープに対応した紙撚糸の長さＬ当たりの逆撚りの回数が、元撚り数Ｎの３．０倍を超えると、加工撚糸に切れが生じやすくなる。 If the number of reverse twists per length L of the paper twisted yarn corresponding to the paper tape of unit length exceeds 3.0 times the original twist number N, the textured twisted yarn is likely to break.
本発明にかかる加工撚糸の製造方法は、上記構成に加え、
「前記異素材糸として少なくとも水溶性糸を使用し、
該水溶性糸は、単位長さの前記紙テープがＮ回撚られることによって長さＬとなった前記紙撚糸に対して、前記逆撚りを２Ｎ回行った後の前記加工撚糸の長さがＬ未満であることにより、前記紙撚糸を撚り縮められるものである」ものである。
The method for producing a textured twisted yarn according to the present invention, in addition to the above configuration,
"Using at least a water-soluble thread as the different material thread,
The water-soluble yarn is the paper twisted yarn having a length L obtained by twisting the paper tape having a unit length N times. By being less than that , the paper twist yarn can be twisted and crimped.
本構成では、異素材糸として少なくとも水溶性糸を使用するが、この水溶性糸は伸縮性の乏しいものを使用する。単位長さの紙テープがＮ回撚られることによって長さＬとなった紙撚糸に対して逆撚りを２Ｎ回行うと、紙撚糸は元撚りとは逆方向にＮ回撚られた状態となる。仮に、水溶性糸が伸縮性に富んでいると、水溶性糸を添わせた紙撚糸を逆撚りする際、水溶性糸は引き伸ばされつつ撚られて行くため、水溶性糸は紙撚糸の長さに影響を与えない。そのため、水溶性糸が伸縮性に富んでいる場合、元撚り状態で長さＬであった紙撚糸は、逆撚り後に同じ長さＬとなる。これに対し、水溶性糸の伸縮性が乏しいと、紙撚糸が撚り数ゼロの状態を超えて逆方向に撚られて行く際、紙撚糸が水溶性糸によって撚り縮められる。すなわち、単位長さの紙テープがＮ回撚られることによって長さＬとなった紙撚糸に対して、逆撚りを２Ｎ回行った後の加工撚糸の長さは、Ｌより短いものとなる。このように水溶性糸によって紙撚糸が撚り縮められている状態の加工撚糸から、水溶性糸を溶解除去すると、それまで縮められていた紙撚糸に元に戻ろうとする力が作用する。これにより、もともとの紙撚糸には乏しかった伸縮性を、加工撚糸に付与することができる。 In this configuration, at least a water-soluble thread is used as the thread of different material, and the water-soluble thread has poor stretchability. When a paper tape having a unit length is twisted N times to obtain a length L of paper twisted yarn and reverse twisting is performed 2N times, the paper twisted yarn is twisted N times in the opposite direction to the original twist. If the water-soluble yarn is highly elastic, when the paper twisted yarn to which the water-soluble yarn is attached is reversely twisted, the water-soluble yarn is stretched and twisted, so the water-soluble yarn is the length of the paper twisted yarn. does not affect the Therefore, when the water-soluble yarn is highly stretchable, the paper twisted yarn having a length L in the original twisted state becomes the same length L after reverse twisting. On the other hand, if the stretchability of the water-soluble yarn is poor, the paper twisted yarn is twisted and contracted by the water-soluble yarn when the paper twisted yarn is twisted in the opposite direction beyond the zero twist state. That is, the length of the twisted paper yarn having a length L obtained by twisting a paper tape of unit length N times becomes shorter than L after reverse twisting is performed 2N times. When the water-soluble yarn is dissolved and removed from the textured twisted yarn in which the paper twisted yarn is twisted and crimped by the water-soluble yarn in this manner, a force acts to restore the paper twisted yarn that has been crimped up to that point. This makes it possible to impart stretchability to the textured twisted yarn, which was originally poor in the paper twisted yarn.
次に、本発明にかかる織編物の製造方法は、
「紙テープに撚りをかけた紙撚糸に、紙とは異なる素材の繊維の糸である異素材糸の少なくとも一種を添え、前記紙撚糸の撚りの方向とは逆方向に撚る逆撚りを行うことにより加工撚糸を得るものであり、
単位長さの前記紙テープがＮ回撚られることによって長さＬの前記紙撚糸となるとき、
前記逆撚りは、前記紙撚糸の長さＬ当たりにＮの１．０倍を超えると共にＮの３．０倍以下の回数の撚りをかけるものである」ものである。
Next, the method for producing a woven or knitted fabric according to the present invention includes:
"A paper twisted yarn obtained by twisting a paper tape is attached with at least one type of yarn of a different material, which is a yarn of a fiber material different from paper, and twisted in the opposite direction to the twisting direction of the paper twisted yarn. A processed twisted yarn is obtained by
When the paper tape of unit length is twisted N times to form the paper twisted yarn of length L,
The counter-twisting is performed by twisting the paper twist yarn more than 1.0 times N and not more than 3.0 times N per length L of the paper twist yarn.
これは、上記の加工撚糸の製造方法により製造された加工撚糸を少なくとも用いて製編織する織編物の製造方法である。異素材糸によって本来の紙に乏しい特性を付与しつつ、加工撚糸の表面に異素材糸が表れにくいため、紙の有する利点を十分に活かした織編物を製造することができる。 This is a method for producing a woven or knitted fabric in which at least the textured twisted yarn produced by the above method for producing a textured twisted yarn is used for knitting or weaving. The yarn of different material imparts properties that are inherently lacking in paper, while the yarn of different material is less likely to appear on the surface of the textured twisted yarn, so that it is possible to produce a woven or knitted fabric that fully utilizes the advantages of paper.
本発明にかかる織編物の製造方法は、上記構成に加え、
「前記異素材糸として少なくとも水溶性糸を使用し、
該水溶性糸は、単位長さの前記紙テープがＮ回撚られることによって長さＬとなった前記紙撚糸に対して、前記逆撚りを２Ｎ回行った後の前記加工撚糸の長さがＬ未満であることにより、前記紙撚糸を撚り縮められるものであり、
前記加工撚糸を製編織する前または後で、前記水溶性糸を水で溶解除去する」ものである。
In addition to the above configuration, the method for producing a woven or knitted fabric according to the present invention includes:
"Using at least a water-soluble thread as the different material thread,
The water-soluble yarn is the paper twisted yarn having a length L obtained by twisting the paper tape having a unit length N times. By being less than, the paper twist yarn can be twisted and contracted,
Before or after knitting and weaving the textured twisted yarn, the water-soluble yarn is dissolved and removed with water .”
これは、上記の加工撚糸の製造方法において、異素材糸として少なくとも水溶性糸を使用する場合に、製造される加工撚糸を少なくとも用いて製編織する織編物の製造方法であり、製編織の前または後で水溶性糸を水で溶解除去する。上述したように、水溶性糸を溶解除去することによって、もともとの紙撚糸には乏しい伸縮性が加工撚糸に大きく発現する。そのため、製編織のために必要な伸縮性が、異素材糸によっては加工撚糸に付与されていない場合は、製編織の前に水溶性糸を溶解除去すれば、製編織のし易い加工撚糸となると共に、伸縮性に富んだ織編物となる。一方、製編織のために必要な伸縮性が異素材糸によって加工撚糸に付与されている場合は、製編織の後で水溶性糸を溶解除去することもできる。これにより、伸縮性に富んだ織編物となると共に、水溶性糸が溶解したあとに形成される空隙により、ふっくらとした風合いや高い通気性を有する織編物となる。 This is a method for producing a woven or knitted fabric by knitting or weaving using at least the produced textured twisted yarn when at least water-soluble yarn is used as the yarn of a different material in the above method for producing a textured twisted yarn. Alternatively, the water-soluble threads are later dissolved and removed with water. As described above, by dissolving and removing the water-soluble yarn, the textured twisted yarn exhibits a large degree of elasticity, which is poor in the original paper twisted yarn. Therefore, if the stretchability required for knitting and weaving is not imparted to the textured twisted yarn by dissolving and removing the water-soluble yarn before knitting and weaving, it becomes a textured twisted yarn that is easy to knit and weave. In addition, it becomes a woven or knitted fabric rich in stretchability. On the other hand, when the stretchability required for knitting and weaving is imparted to the textured twisted yarn by a yarn of a different material, the water-soluble yarn can be dissolved and removed after knitting and weaving. As a result, the woven or knitted fabric is highly stretchable, and the woven or knitted fabric has a soft texture and high air permeability due to voids formed after the water-soluble yarn is dissolved.
以上のように、本発明によれば、紙とは異なる素材の繊維によって紙撚糸の難点を改善することができると共に、紙の利点を損なうことがない加工撚糸の製造方法、及び、該製造方法により製造された加工撚糸を使用した織編物の製造方法を、提供することができる。 As described above, according to the present invention, the disadvantages of paper twisted yarn can be improved by using fibers of a material different from paper, and a method for producing textured twisted yarn that does not impair the advantages of paper, and the method for producing it. It is possible to provide a method for producing a woven or knitted fabric using the textured twisted yarn produced by.
以下、本発明の具体的な実施形態である加工撚糸の製造方法、及び、該製造方法により製造された加工撚糸を使用した織編物の製造方法について説明する。 Hereinafter, a method for producing a textured twisted yarn, which is a specific embodiment of the present invention, and a method for producing a woven or knitted fabric using the textured twisted yarn produced by the production method will be described.
まず、本実施形態の加工撚糸の製造方法は、紙テープに撚りをかけた紙撚糸に、紙とは異なる素材の繊維の糸である異素材糸の少なくとも一種を添え、紙撚糸の撚りの方向とは逆方向に撚る逆撚りを行うことにより加工撚糸を得るものである。 First, in the method for producing a textured twisted yarn of the present embodiment, at least one type of yarn of a different material, which is a yarn of a fiber material different from paper, is added to a paper twisted yarn obtained by twisting a paper tape, and the twist direction of the paper twisted yarn is changed. is obtained by twisting in the opposite direction to obtain a textured twisted yarn.
紙としては、アサ、コウゾ、ミツマタ、ガンピの樹皮から採取した繊維を含む原料や、木材パルプを含む原料を抄紙して得た紙を、特に限定することなく使用することができる。紙テープの幅は特に限定されるものではないが、幅１ｍｍ～５ｍｍであれば、撚り合わせる異素材糸の選択の幅が広く好適である。紙テープを紙撚糸にする際の撚り（元撚り）の回数は、紙テープ１メートル当たり２００回～１５００回とすることができる。 As the paper, raw materials containing fibers collected from the bark of hemp, paper mulberry, mitsumata, and gampi, and papers obtained by making paper from raw materials containing wood pulp can be used without particular limitation. The width of the paper tape is not particularly limited, but a width of 1 mm to 5 mm is preferable because it allows a wide range of choices for threads of different materials to be twisted together. The number of twists (original twists) when the paper tape is turned into paper twisted yarn can be 200 to 1500 times per meter of the paper tape.
異素材糸は、フィラメント糸（長繊維）であっても紡績糸であっても良い。フィラメント糸としては、ポリウレタン弾性糸を使用することができる。また、その他のフィラメント糸として、ポリエステル系繊維、ポリアミド系繊維、アクリル系繊維、ポリプロピレン系繊維、セルロース系再生繊維（ビスコースレーヨン、銅アンモニアレーヨン）を例示することができる。フィラメント糸は、モノフィラメント糸でもマルチフィラメント糸でも良い。更に、フィラメント糸は捲縮糸であっても良く、捲縮糸としてはコンジュゲート糸や仮撚加工糸を使用することができる。 The different material yarn may be a filament yarn (long fiber) or a spun yarn. Polyurethane elastic threads can be used as filament threads. Examples of other filament yarns include polyester fibers, polyamide fibers, acrylic fibers, polypropylene fibers, and regenerated cellulose fibers (viscose rayon, cuprammonium rayon). The filament yarn may be a monofilament yarn or a multifilament yarn. Furthermore, the filament yarn may be a crimped yarn, and the crimped yarn may be a conjugate yarn or a false twisted yarn.
異素材糸としての紡績糸は、木綿、羊毛、絹、麻などの天然繊維、ポリエステル系繊維、ポリアミド系繊維、アクリル系繊維、ポリプロピレン系繊維、セルロース系再生繊維などから選ばれる、一種または二種以上の繊維からなる紡績糸を使用することができる。 Spun yarn as foreign material yarn is one or two types selected from natural fibers such as cotton, wool, silk, hemp, etc., polyester fibers, polyamide fibers, acrylic fibers, polypropylene fibers, regenerated cellulose fibers, etc. A spun yarn composed of the above fibers can be used.
これらの異素材糸から選ばれる一種または二種以上の異素材糸を、紙撚糸に添わせた状態で、元撚りの方向とは逆方向に撚る逆撚りを行う。この逆撚りは、単位長さの紙テープがＮ回撚られることによって長さＬの紙撚糸となっているとき、長さＬの紙撚糸に対して次の関係を満たす回数Ｍだけ撚るものである。
Ｎ×１．０ ＜ Ｍ ≦ Ｎ×３．０
One or two or more types of different material yarns selected from these different material yarns are twisted in the opposite direction to the original twisting direction in a state of being attached to the paper twisted yarn. In this reverse twisting, when a unit-length paper tape is twisted N times to form a paper twisted yarn of length L, the paper twisted yarn of length L is twisted M times that satisfy the following relationship: be.
N x 1.0 < M ≤ N x 3.0
回数ＭがＮの１．０倍を超えていることにより、元撚りされていた紙撚糸は、撚り数ゼロの状態を超えて、更に元撚りとは逆方向に撚られる。元撚りされた紙撚糸に添えられた状態から紙撚糸と共に逆撚りされる異素材糸は、紙撚糸が撚り数ゼロとなって元の紙テープ状に戻り、更にその状態を超えて逆方向に撚られるとき、紙テープの内側に巻き込まれるように撚り合わされる。従って、逆撚り後の加工撚糸の表面には、異素材糸は表れにくい。 Since the number M exceeds 1.0 times N, the original twisted paper yarn exceeds the state where the number of twists is zero, and is further twisted in the direction opposite to the original twist. A different material thread that is reversely twisted together with the paper twisted yarn from the state attached to the original twisted paper yarn returns to the original paper tape shape with the number of twists of the paper twisted yarn being zero, and then beyond that state and twisted in the opposite direction. When folded, it is twisted so that it is wrapped inside the paper tape. Therefore, the yarn of different material is less likely to appear on the surface of the textured twisted yarn after reverse twisting.
ここで、単位長さの紙テープに対応した紙撚糸の長さＬ当たりの逆撚りの回数Ｍが、元撚り数Ｎの３．０倍を超えると、加工撚糸に切れが生じやすくなる。また、この逆撚りの回数Ｍは、Ｎの１．３倍以上で２．７倍以下であれば異素材糸が表面により表れにくく、糸切れがより生じにくいため望ましい。また、この逆撚りの回数Ｍは、Ｎの１．５倍以上であれば異素材糸が表面に更に表れにくいため更に望ましく、Ｎの１．８倍以上であれば異素材糸が表面にほとんど表れないため特に好ましい。一方、この逆撚りの回数がＮの１．０倍を超え、且つ１．３倍未満の範囲であれば、異素材糸が表面に表れにくいと共に、無撚の状態に近く、柔らかな風合いの加工撚糸となる。 Here, if the number of reverse twists M per length L of the paper twisted yarn corresponding to the paper tape of unit length exceeds 3.0 times the number of original twists N, the textured twisted yarn tends to break. Moreover, it is desirable that the number of reverse twists M is 1.3 times or more and 2.7 times or less than N, because the yarn of a different material is less likely to appear on the surface and yarn breakage is less likely to occur. In addition, if the number of reverse twists M is 1.5 times or more than N, the yarn of different material is more difficult to appear on the surface, so it is more preferable. It is particularly preferred because it does not appear. On the other hand, if the number of reverse twists exceeds 1.0 times N and is less than 1.3 times N, the yarn of a different material is less likely to appear on the surface, and the yarn is close to untwisted and has a soft texture. It becomes processed twisted yarn.
更に、異素材糸としては、水溶性糸を使用することができる。水溶性糸は、沸点より低い温度の水に浸漬したとき、長時間を要することなく溶解するものが望ましい。具体的には、水溶性糸を単独で温度９０℃の水に浸漬して３０分間放置したときに、浸漬前の水溶性糸の質量に対して８５質量％以上が溶解する水溶性を示すものが望ましく、９５質量％以上が溶解する水溶性を示すものがより望ましい。このような水溶性糸としては、水溶性ポリビニルアルコール系繊維、水溶性エチレン－ビニルアルコール系共重合体繊維、水溶性ポリアミド繊維からなるものを使用することができる。水溶性糸は、フィラメント糸であっても紡績糸であっても良い。 Furthermore, a water-soluble thread can be used as the different material thread. It is desirable that the water-soluble thread dissolves without requiring a long time when immersed in water having a temperature lower than the boiling point. Specifically, when the water-soluble thread is immersed in water at a temperature of 90° C. and allowed to stand for 30 minutes, 85% by mass or more of the water-soluble thread before immersion dissolves in water. is preferable, and those exhibiting water solubility in which 95% by mass or more is dissolved are more preferable. As such a water-soluble thread, a water-soluble polyvinyl alcohol fiber, a water-soluble ethylene-vinyl alcohol copolymer fiber, or a water-soluble polyamide fiber can be used. The water-soluble yarn may be filament yarn or spun yarn.
異素材糸として水溶性糸を使用するとき、この水溶性糸は伸縮性の乏しいものを使用する。単位長さの紙テープがＮ回撚られることによって長さＬとなった紙撚糸に対して、逆撚りを２Ｎ回行うと、元撚りとは逆方向にＮ回撚られた紙撚糸となるが、水溶性糸の伸縮性が乏しい場合、紙撚糸が撚り数ゼロの状態を超えて逆方向に撚られて行く際、紙撚糸が水溶性糸によって撚り縮められるため、逆撚り後の加工撚糸の長さはＬより短いものとなる。 When a water-soluble thread is used as the thread of a different material, the water-soluble thread has poor stretchability. If a paper tape having a unit length is twisted N times to obtain a length L, and the reverse twist is performed 2N times, the paper twist yarn is twisted N times in the opposite direction to the original twist. If the stretchability of the water-soluble yarn is poor, when the paper twisted yarn is twisted in the opposite direction beyond the state where the number of twists is zero, the paper twisted yarn is twisted and contracted by the water-soluble yarn, so the length of the processed twisted yarn after reverse twisting length is shorter than L.
異素材糸としては、水溶性糸ではない異素材糸のみを一種または二種以上使用しても良いし、水溶性糸のみを使用しても良いし、水溶性糸と水溶性糸ではない異素材糸の一種または二種以上を組み合わせて使用しても良い。 As the different material threads, only one or more types of different material threads that are not water-soluble threads may be used, or only water-soluble threads may be used, or a water-soluble thread and a different non-water-soluble thread may be used. One or a combination of two or more types of material yarns may be used.
次に、本実施形態の織編物の製造方法について説明する。織編物の製造方法は、上記の実施形態の加工撚糸の製造方法により製造された加工撚糸を、製編織する対象の糸の少なくとも一部に使用して製編織するものである。異素材糸の存在によって、加工撚糸の引張り強度や引裂き強度は紙撚糸より高められているため、紙撚糸だけを製編織する場合に比べて製編織がし易い。また、加工撚糸を製編織して製造された織編物の引張り強度や引裂き強度も、紙撚糸だけが製編織された織編物に比べて高められる。 Next, a method for manufacturing the woven or knitted fabric of this embodiment will be described. In the method for producing a woven or knitted fabric, the textured twisted yarn produced by the method for producing the textured twisted yarn of the above-described embodiment is used for at least part of the yarn to be knitted and woven. Due to the presence of the yarn of a different material, the tensile strength and tear strength of the textured twisted yarn are higher than those of the paper twisted yarn, making knitting and weaving easier than in the case of knitting and weaving only with paper twisted yarn. In addition, the tensile strength and tear strength of the woven or knitted fabric produced by knitting or weaving the textured twisted yarn are enhanced compared to the woven or knitted fabric produced by knitting or weaving only the paper twisted yarn.
また、異素材糸として伸縮性に富んだ糸を使用すれば、加工撚糸の伸縮性を紙撚糸より高めることができるため、紙撚糸だけを製編織する場合に比べて製編織がし易い。 In addition, if a highly stretchable yarn is used as the yarn of a different material, the stretchability of the textured twisted yarn can be made higher than that of the paper twisted yarn.
加えて、紙撚糸と異素材糸とを逆撚りしていることにより、加工撚糸の表面に異素材糸が表れにくいため、加工撚糸を製編織して製造された織編物の表面にも異素材糸が表れにくい。換言すれば、織編物の表面における紙の割合を十分に高めることができ、紙の有する優れた吸湿性や放湿性を、十分に発揮する織編物を製造することができる。例えば、アサを原料とする紙撚糸（王子ファイバー株式会社製、ＯＪＯ＋（登録商標）、１５１５スタンダード、メートル番手１／４１）と綿糸（メートル番手２０／１）とで吸湿性、及び放湿性を対比すると、次のようである。
＜吸湿性＞
紙撚糸：１１．８０％
綿糸：１１．９０％
＜放湿性＞
紙撚糸：１５．４０％
綿糸：２５．００％
In addition, because the paper twisted yarn and the different material yarn are reversely twisted, the different material yarn is less likely to appear on the surface of the textured twisted yarn, so the surface of the woven or knitted fabric produced by knitting the textured twisted yarn Threads are hard to show. In other words, the ratio of paper on the surface of the woven or knitted fabric can be sufficiently increased, and a woven or knitted fabric that fully exhibits the excellent moisture absorption and moisture release properties of paper can be produced. For example, paper twisted yarn (manufactured by Oji Fiber Co., Ltd., OJO + (registered trademark), 1515 standard, metric count 1/41) made from hemp and cotton yarn (metric count 20/1) are used to improve moisture absorption and moisture release. A comparison is as follows.
<Hygroscopicity>
Paper twist yarn: 11.80%
Cotton thread: 11.90%
<Moisture release>
Paper twist yarn: 15.40%
Cotton thread: 25.00%
つまり、紙撚糸は、吸湿性が高い繊維であると言われている綿糸と同程度の吸湿性を有し、放湿性（乾燥のし易さ）は綿糸に比べて非常に高い。ここで、吸湿性は、絶乾試料を温度２０℃、相対湿度９５％の恒温恒湿空間に６０分間放置した後の水分率で評価しており、数値が大きいほど吸湿性が高い。また、放湿性は、水に完全に浸漬した試料を脱水後に質量測定し、その試料を温度２０℃、相対湿度６５％の恒温恒湿空間に６０分間放置した後の水分率で評価しており、数値が小さいほど放湿性が高く乾燥しやすい。 In other words, the paper twisted yarn has a hygroscopicity similar to that of cotton yarn, which is said to be a fiber with high hygroscopicity, and its moisture releasing property (dryability) is much higher than that of cotton yarn. Here, the hygroscopicity was evaluated by the moisture content after leaving the absolute dry sample in a constant temperature and humidity space of 20° C. and 95% relative humidity for 60 minutes. In addition, the moisture release property is evaluated by measuring the weight of a sample completely immersed in water after dehydration, and evaluating the moisture content after leaving the sample in a constant temperature and humidity space at a temperature of 20 ° C. and a relative humidity of 65% for 60 minutes. , The smaller the number, the higher the moisture release and the easier it is to dry.
異素材糸として水溶性糸のみを使用した加工撚糸を製編織する場合、或いは、異素材糸として二種以上を使用し、その中に水溶性糸を含んでいる加工撚糸を製編織する場合、製編織の前または後で水溶性糸を水で溶解除去する。加工撚糸では水溶性糸によって紙撚糸が撚り縮められた状態にあるため、その加工撚糸から水溶性糸を溶解除去すると、それまで縮められていた状態から元に戻ろうとする力が紙撚糸に作用する。従って、製編織の前に水溶性糸を溶解除去する場合は、加工撚糸に発現する伸縮性によって製編織がし易くなると共に、伸縮性に富んだ織編物が製造される。一方、製編織の後に水溶性糸を溶解除去する場合は、伸縮性に富んだ織編物が製造されると共に、水溶性糸が溶解したあとに形成される空隙により、ふっくらとした風合いを有し通気性の高い織編物となる。 When knitting or weaving a textured twisted yarn that uses only water-soluble yarn as a different material yarn, or when knitting or weaving a textured twisted yarn that uses two or more types of different material yarns and contains water-soluble yarn, Before or after knitting and weaving, the water-soluble yarn is dissolved and removed with water. In textured twisted yarn, the paper twisted yarn is twisted and crimped by the water-soluble yarn, so when the water-soluble yarn is dissolved and removed from the textured twisted yarn, a force acts on the paper twisted yarn to return it from the contracted state. do. Therefore, when the water-soluble yarn is dissolved and removed before knitting and weaving, the elasticity developed in the textured twisted yarn facilitates knitting and weaving, and a woven or knitted fabric with high elasticity is produced. On the other hand, when the water-soluble yarn is dissolved and removed after knitting and weaving, a woven or knitted fabric with high elasticity is produced, and the voids formed after the water-soluble yarn is dissolved have a soft texture. A woven or knitted fabric having high air permeability is obtained.
紙撚糸（王子ファイバー株式会社製、ＯＪＯ＋（登録商標）、１５１５スタンダード、メートル番手１／４１、左撚り５００回／ｍ）に、ポリエチレン系マルチフィラメント糸（１４４本）、１５０デニールを添え、長さ１ｍの紙テープに対応した紙撚糸の長さ（長さ１ｍの紙テープを５００回左撚りしたときの長さ）当たり１０００回、右撚り（逆撚り）することにより、実施例Ｓ１の加工撚糸を製造した。ここでの逆撚り数は、単位長さの紙テープに対応した紙撚糸の長さ当たり、元撚り数Ｎの２．０倍である。 Paper twisted yarn (manufactured by Oji Fiber Co., Ltd., OJO + (registered trademark), 1515 standard, metric count 1/41, left twist 500 times / m), polyethylene-based multifilament yarn (144 yarns), 150 denier attached, long The textured twisted yarn of Example S1 is twisted to the right (reverse twist) 1000 times per length of the paper twisted yarn corresponding to the paper tape of 1 m in length (the length when the paper tape of 1 m in length is twisted to the left 500 times). manufactured. The reverse twist number here is 2.0 times the original twist number N per length of paper twist yarn corresponding to a unit length of paper tape.
実施例Ｓ１と同一の紙撚糸（左撚り５００回／ｍ）に、ポリウレタン弾性糸（東レ・オペロンテックス株式会社製、ライクラ（登録商標）、４０デニール・３フィラメント）を添え、長さ１ｍの紙テープに対応した紙撚糸の長さ当たり１０００回、右撚り（逆撚り）することにより、実施例Ｓ２の加工撚糸を製造した。 Polyurethane elastic yarn (Lycra (registered trademark), 40 denier, 3 filaments, manufactured by Toray Operontex Co., Ltd.) is attached to the same paper twisted yarn (left twist 500 times / m) as in Example S1, and a paper tape of 1 m in length is prepared. The textured twist yarn of Example S2 was produced by right twisting (reverse twisting) 1000 times per length of paper twist yarn corresponding to .
実施例Ｓ１，Ｓ２と同一の紙撚糸（左撚り５００回／ｍ）に、水溶性ポリビニルアルコール系水溶性糸（クラレトレーディング株式会社製、ミントバール（登録商標）、５０デニール）を添え、長さ１ｍの紙テープに対応した紙撚糸の長さ当たり１０００回、右撚り（逆撚り）することにより、実施例Ｓ１１の加工撚糸を製造した。 A water-soluble polyvinyl alcohol-based water-soluble yarn (manufactured by Kuraray Trading Co., Ltd., Mint Bar (registered trademark), 50 denier) was attached to the same paper twist yarn (left twist 500 times / m) as in Examples S1 and S2, and the length The textured yarn of Example S11 was produced by right twisting (reverse twisting) 1000 times per length of paper yarn corresponding to 1 m of paper tape.
実施例Ｓ１，Ｓ２，Ｓ１１と同一の紙撚糸（左撚り５００回／ｍ）に、実施例Ｓ２と同一のポリウレタン弾性糸、４０デニール・３フィラメント、及び、実施例Ｓ１１と同一の水溶性ポリビニルアルコール系水溶性糸、５０デニールを添え、長さ１ｍの紙テープに対応した紙撚糸の長さ当たり１０００回、右撚り（逆撚り）することにより、実施例Ｓ１２の加工撚糸を製造した。 The same polyurethane elastic yarn as in Example S2, 40 denier 3 filaments, and the same water-soluble polyvinyl alcohol as in Example S11 were added to the same paper twisted yarn (left twist 500 times/m) as in Examples S1, S2, and S11. The textured twisted yarn of Example S12 was produced by adding a 50 denier system water-soluble yarn and right twisting (reverse twisting) 1000 times per length of paper twisted yarn corresponding to a 1 m long paper tape.
比較のために、実施例Ｓ１，Ｓ２，Ｓ１１、Ｓ１２と同一の紙撚糸（左撚り５００回／ｍ）だけで異素材糸と逆撚りしていない糸を、比較例Ｒ１の撚糸とした。また、綿１００％の紡績糸（番手１／１６）を、比較例Ｒ２の撚糸とした。 For comparison, the same paper twisted yarn (left twist 500 times/m) as in Examples S1, S2, S11, and S12 but not reversely twisted with a different material yarn was used as the twisted yarn of Comparative Example R1. A 100% cotton spun yarn (1/16 count) was used as the twisted yarn of Comparative Example R2.
ここで、実施例Ｓ１１では、水溶性糸と共に逆撚りした後の加工撚糸の長さは、逆撚りを開始する前の紙撚糸の長さの８７％～８８％であり、大きく撚り縮められていた。これは、水溶性糸の伸縮性が乏しいためと考えられた。一方、実施例Ｓ２では、ポリウレタン弾性糸と共に逆撚りした後の加工撚糸の長さは、逆撚りをする前の紙撚糸の長さ、すなわち、異素材糸と逆撚りをしていない比較例Ｒ１の紙撚糸の長さと同一であった。これは、ポリウレタン弾性糸が非常に伸縮性に富んでいるために、ポリウレタン弾性糸が引き伸ばされつつ逆撚りが進行するためと考えられた。 Here, in Example S11, the length of the textured twisted yarn after reverse twisting with the water-soluble yarn was 87% to 88% of the length of the paper twisted yarn before the reverse twisting was started, and the twist was greatly reduced. rice field. This was thought to be due to the poor stretchability of the water-soluble yarn. On the other hand, in Example S2, the length of the textured twisted yarn after reverse twisting with the polyurethane elastic yarn was the length of the paper twisted yarn before reverse twisting, that is, the length of the paper twisted yarn before reverse twisting, i. It was the same as the length of the paper twist yarn. This is thought to be due to the fact that the polyurethane elastic yarn is highly stretchable, and thus reverse twisting proceeds while the polyurethane elastic yarn is being stretched.
実施例Ｓ１，Ｓ２，Ｓ１１，Ｓ１２の加工撚糸、及び、比較例Ｒ１，Ｒ２の撚糸について、ＪＩＳ Ｌ１０１３（化学繊維フィラメント糸試験方法、２０１０年）が規定する伸縮性Ｃ法に準拠して、伸縮性の評価を行った。異素材糸として水溶性糸を使用している実施例Ｓ１１、Ｓ１２の加工撚糸については、水溶性糸を水で溶解除去してから伸縮性の評価を行った。水溶性糸の溶解除去は、枠周１ｍの検尺機を使用し加工撚糸に初荷重をかけて巻き数１０回のかせを作成し、治具に巻き付けたかせを温度９０℃±２℃の水に３０分浸漬することにより行い、水溶性糸を除去した後の加工撚糸を温水で洗浄し吊り下げ乾燥させた後、伸縮性の評価を行った。加工撚糸を浸漬する水には、非イオン界面活性剤（第一工業製薬株式会社製、ノイゲン（登録商標）ＥＡ－１２０）を２ｇ／Ｌの濃度となるように添加した。各試料について測定された伸縮伸長率（％）を、表１に示す。 The textured twisted yarns of Examples S1, S2, S11, and S12 and the twisted yarns of Comparative Examples R1 and R2 were stretched according to the elasticity C method specified by JIS L1013 (chemical fiber filament yarn test method, 2010). sex was evaluated. For the textured twisted yarns of Examples S11 and S12 in which the water-soluble yarn was used as the yarn of a different material, the stretchability was evaluated after the water-soluble yarn was dissolved and removed with water. To dissolve and remove the water-soluble yarn, use a measuring machine with a frame circumference of 1 m and apply an initial load to the processed twisted yarn to create a skein with 10 turns, and then soak the skein wound around the jig in water at a temperature of 90 ° C ± 2 ° C. After removing the water-soluble yarn, the textured twisted yarn was washed with warm water and hung to dry, and then the stretchability was evaluated. A nonionic surfactant (Noigen (registered trademark) EA-120, manufactured by Daiichi Kogyo Seiyaku Co., Ltd.) was added to the water in which the textured twisted yarn was immersed so that the concentration was 2 g/L. Table 1 shows the stretch ratio (%) measured for each sample.
表１に示すように、紙撚糸（比較例Ｒ１）の伸縮伸長率は０．６％と、綿糸（比較例Ｒ２）の１．０％より小さく、伸縮性に乏しい。これに対し、水溶性糸ではない異素材糸と逆撚りした実施例Ｓ１，Ｓ２の加工撚糸では、伸縮伸長率が１．７％，２．０％と高められている。更に、異素材糸として水溶性糸を使用している実施例Ｓ１１，Ｓ１２の加工撚糸では、伸縮伸長率が６．０％，８．６％と大きく高められている。これは、伸縮性に乏しい水溶性糸と共に逆撚りすることによって撚り縮められていた紙撚糸から、その状態を拘束していた水溶性糸が除去されることにより、元に戻ろうとする力が作用して、紙撚糸に伸縮性が生じたためと考えられた。 As shown in Table 1, the paper twisted yarn (Comparative Example R1) has a stretch elongation rate of 0.6%, which is smaller than the cotton yarn (Comparative Example R2) of 1.0%, and has poor stretchability. On the other hand, the textured twisted yarns of Examples S1 and S2, which are reversely twisted with yarns of a different material that are not water-soluble yarns, have increased expansion and contraction rates of 1.7% and 2.0%, respectively. Furthermore, in the textured twisted yarns of Examples S11 and S12, in which water-soluble yarns are used as yarns of a different material, the expansion and contraction rates are significantly increased to 6.0% and 8.6%. This is because the paper twisted yarn that has been twisted and crimped together with the water-soluble yarn with poor stretchability is removed from the twisted paper yarn, and the water-soluble yarn that restrains that state is removed, and a force that tries to return it to its original state acts. This is thought to be due to the fact that the paper twisted yarn became stretchable.
また、異素材糸として水溶性糸のみを使用した実施例Ｓ１１より、異素材糸として水溶性糸に加えてポリウレタン弾性糸を使用した実施例Ｓ１２の方が、伸縮伸長率がより大きく高められている。これは、紙撚糸を撚り縮めていた水溶性糸の消失により紙撚糸に伸縮性が発現したことと、水溶性糸の消失によってポリウレタン弾性糸が自身の伸縮性をより発揮できるようになったこと、との相乗効果によるものと考えられた。 In addition, compared to Example S11 in which only the water-soluble thread was used as the thread of the different material, Example S12 in which the polyurethane elastic thread was used in addition to the water-soluble thread as the thread of the different material showed a greater increase in the expansion and contraction rate. there is This is because the paper twisted yarn became elastic due to the disappearance of the water-soluble yarn that twisted and contracted the paper twisted yarn, and the polyurethane elastic yarn became able to exhibit its own elasticity due to the disappearance of the water-soluble yarn. was thought to be due to a synergistic effect with
水溶性糸を除去する前の実施例Ｓ１２の加工撚糸を横糸（緯糸）に使用し、経糸に綿糸を使用して製編織することにより、実施形態の織編物を製造した。織編物は、朱子織のジーンズ生地とし、横糸が裏面に多く表れるようにした。紙撚糸のみを製編織する場合は、製編織が困難で歩留まりが３０％程度であるところ、実施例Ｓ１２の加工撚糸の製編織は非常にスムーズであり、歩留まりは１００％であった。製編織後に、織編物から水溶性糸を水で溶解除去した。 The woven and knitted fabric of the embodiment was produced by knitting and weaving using the textured twisted yarn of Example S12 before removing the water-soluble yarn as the weft yarn (weft yarn) and using the cotton yarn as the warp yarn. The woven and knitted fabric is a satin weave jeans fabric, and the weft threads are made to appear more on the back side. When knitting and weaving only paper twisted yarn, knitting and weaving is difficult and the yield is about 30%, but knitting and weaving of the textured twisted yarn of Example S12 was very smooth and the yield was 100%. After the knitting and weaving, the water-soluble yarn was dissolved and removed from the woven or knitted fabric with water.
水溶性糸を溶解除去した後の織編物は、非常に伸縮性に富んでおり、特に横方向の伸縮性が高いものであった。また、ジーンズ生地の裏面はほぼ全体に紙が表れており、紙特有のドライでさらさらとした感触であった。ジーンズ生地でジーンズ（ズボン）を作製した場合、裏面は着用者の肌に接することとなる。そのため、紙の有する優れた吸湿性によって汗が速やかに生地に吸収され、更に紙の有する優れた放湿性によって速やかに放散されるため、快適な着心地となると考えられた。 The woven or knitted fabric after dissolving and removing the water-soluble yarn had a very high stretchability, particularly a high stretchability in the lateral direction. Moreover, paper appeared on almost the entire back surface of the jeans fabric, and the feeling was dry and smooth, which is peculiar to paper. When jeans (trousers) are made from the jeans material, the back side comes into contact with the wearer's skin. Therefore, sweat is quickly absorbed by the fabric due to the excellent hygroscopicity of paper, and is quickly dissipated due to the excellent moisture releasing property of paper, which is considered to be comfortable to wear.
以上、本発明について好適な実施形態を挙げて説明したが、本発明は上記の実施形態に限定されるものではなく、以下に示すように、本発明の要旨を逸脱しない範囲において、種々の改良及び設計の変更が可能である。 As described above, the present invention has been described with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and as shown below, various improvements can be made without departing from the scope of the present invention. and design changes are possible.
例えば、上記では、実施例Ｓ１２の加工撚糸を製編織し、製編織の後で水溶性糸を溶解除去する場合を例示したが、実施例Ｓ１１の加工撚糸を製編織した場合も、非常に伸縮性に富んだ織編物を得ることができる。この場合は、製編織の前に水溶性糸を除去すれば、非常に伸縮性の高い加工撚糸となるため、良好に製編織を行うことができる。
For example, in the above, the case where the textured twisted yarn of Example S12 is knitted and woven, and the water-soluble yarn is dissolved and removed after the knitting and weaving is illustrated. A woven or knitted fabric rich in properties can be obtained. In this case, if the water-soluble yarn is removed before knitting and weaving, the textured twisted yarn can be obtained with extremely high elasticity, so that knitting and weaving can be carried out satisfactorily.
