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 processed twisted yarn using a paper twisted yarn, and a method for producing a woven or knitted fabric for knitting or weaving the processed twisted yarn produced by the 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。 BACKGROUND ART Twisted paper tape obtained by twisting paper tape obtained by cutting paper into a narrow width, and woven or knitted fabric obtained by knitting and weaving paper twisted yarn are well known. Paper has advantages such as excellent water absorption and hygroscopicity, high moisture release and easy drying, and a unique dry feel.
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, twisted paper yarns have drawbacks in that they have low tensile strength and tear strength and are difficult to knit and weave because of poor stretchability. Therefore, conventionally, attempts have been made to improve the difficulty of the paper twisted yarn by twisting fibers of a material different from paper with a paper tape or a paper twisted yarn (for example, see 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 fibers of a material different from paper with a paper tape or paper twisted yarn, fibers of a material different from paper appear on the surface. The above advantages of water absorption / absorption, moisture release, and dry feel are mainly due to the properties of the surface of the twisted yarn. Therefore, in the conventional attempt, the advantage of the paper was sometimes impaired by the fiber of the different material used to improve the difficulty of the paper twisting yarn.
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。 In view of the above circumstances, the present invention can improve the drawbacks of paper twisted yarn by using fibers of a material different from paper, and can also provide a method for manufacturing a processed twisted yarn that does not impair the advantages of paper, and the manufacturing method. An object of the present invention is to provide a method for producing a woven or knitted fabric using a processed 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, a method for producing a processed twisted yarn according to the present invention includes:
`` Applying at least one kind of different material yarn, which is a yarn of a fiber different from paper, to a paper twisted yarn obtained by twisting a paper tape, and performing reverse twisting in a direction opposite to the twisting direction of the paper twisting yarn. To obtain a processed twisted yarn,
When the unit length of the paper tape is twisted N times to become the length of the paper twisted yarn,
In the reverse twisting, twisting is performed more than 1.0 times N and not more than 3.0 times N per length L of the paper twisted 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 twist when the paper tape is used as the paper twist yarn is referred to as “primary twist”.
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, a twisted yarn is obtained by twisting the paper twisted yarn in a direction opposite to the original twisting with a different material yarn attached. The number of times of reverse twist is set to a number exceeding 1.0 times N per unit length L of the paper twisted yarn when a unit length paper tape is twisted N times to form a paper twisted yarn having a length L. That is, the paper twisted yarn is twisted in the direction opposite to the original twist, exceeding the state where the number of twists is zero. Different material yarns twisted together with the paper twisted yarn from the state attached to the original twisted paper twisted yarn, when the number of twists of the paper twisted yarn is reduced to zero and returned to the original paper tape shape, and further twisted in the opposite direction beyond that state , So as to be wound inside the paper tape. Therefore, different material yarns are less likely to appear on the surface of the processed twisted yarn after reverse twisting. For this reason, it is possible to manufacture a processed twisted yarn in which the advantage of the paper is greatly reduced. And, since the properties of the different material yarns can impart poor properties to the original paper, it is possible to obtain a processed twisted yarn in which the difficulty of the paper twisted yarn is 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 unit length of paper tape exceeds 3.0 times the number of original twists N, the processed twisted yarn is likely to be cut.
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」ものとすることができる。
The method for producing a processed twisted yarn according to the present invention, in addition to the above configuration,
"Using at least a water-soluble yarn as the different material yarn,
The water-soluble yarn has a length of the processed twisted yarn after performing the reverse twisting 2N times with respect to the paper twisted yarn having a length L by twisting the unit length of the paper tape N times. By being less than the above, the paper twisted yarn can be twisted and shrunk. "
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 yarn is used as the different material yarn, but this water-soluble yarn uses a material having poor elasticity. When reverse twisting is performed 2N times on a paper twisted yarn having a length L by twisting a unit length of paper tape N times, the paper twisted yarn is twisted N times in the direction opposite to the original twist. If the water-soluble yarn is rich in elasticity, the reverse twist of the paper twisted yarn with the water-soluble yarn will cause the water-soluble yarn to be twisted while being stretched. Does not affect the performance. Therefore, when the water-soluble yarn is rich in elasticity, the paper twisted yarn having the length L in the original twist state has the same length L after the 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 processed twisted yarn after performing the reverse twisting 2N times with respect to the paper twisted yarn having the length L by twisting the unit length paper tape N times is shorter than L. When the water-soluble yarn is dissolved and removed from the processed twisted yarn in a state where the paper twisted yarn is twisted and reduced by the water-soluble yarn in this way, a force to return the paper twisted yarn that has been compressed to the original state acts. This makes it possible to impart stretchability, which was insufficient for the original paper twisted yarn, to the processed 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 comprises:
`` Applying at least one kind of different material yarn, which is a yarn of a fiber different from paper, to a paper twisted yarn obtained by twisting a paper tape, and performing reverse twisting in a direction opposite to the twisting direction of the paper twisting yarn. To obtain a processed twisted yarn,
When the unit length of the paper tape is twisted N times to become the length of the paper twisted yarn,
In the reverse twisting, twisting is performed more than 1.0 times N and 3.0 times or less N per length L of the paper twisted 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 that is knitted and woven using at least the processed twisted yarn produced by the above-described method for producing a processed twisted yarn. Since different material yarns are unlikely to appear on the surface of the processed twisted yarn while imparting poor properties to the original paper by the different material yarns, it is possible to manufacture 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」ものとすることができる。
The method for producing a woven or knitted fabric according to the present invention, in addition to the above configuration,
"Using at least a water-soluble yarn as the different material yarn,
The water-soluble yarn has a length of the processed twisted yarn after performing the reverse twisting 2N times with respect to the paper twisted yarn having a length L by twisting the unit length of the paper tape N times. By being less than, it is possible to twist and shrink the paper twist yarn,
Before or after knitting and weaving the processed 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 in which at least a water-soluble yarn is used as a different material yarn in the above-described method for producing a processed twisted yarn, the knitting and weaving is performed by using at least the processed twisted yarn to be produced. Alternatively, the water-soluble yarn is dissolved and removed later with water. As described above, by dissolving and removing the water-soluble yarn, the stretchability, which is poor in the original paper twist yarn, is greatly exhibited in the processed twist yarn. Therefore, if the elasticity required for weaving is not imparted to the processed twisted yarn due to the different material yarns, if the water-soluble yarn is dissolved and removed before weaving, the processed twisted yarn can be easily knitted. It becomes a woven and knitted fabric with rich elasticity. On the other hand, when the stretch necessary for knitting and weaving is imparted to the processed twist yarn by the different material yarn, the water-soluble yarn can be dissolved and removed after knitting and weaving. As a result, a woven / knitted fabric having a high elasticity is obtained, and a woven / knitted fabric having a plump texture and high air permeability due to a void 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。 INDUSTRIAL APPLICABILITY As described above, according to the present invention, it is possible to improve the difficulty of a paper twisted yarn by using a fiber of a material different from paper, and a method of manufacturing a processed twisted yarn that does not impair the advantages of paper, and the manufacturing method And a method for producing a woven or knitted fabric using the processed twisted yarn produced by the method described above.
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 manufacturing a processed twist yarn, which is a specific embodiment of the present invention, and a method for manufacturing a woven or knitted fabric using the processed twist yarn manufactured by the manufacturing 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, the method for producing a processed twisted yarn of the present embodiment is to add at least one kind of a different material yarn which is a yarn of a fiber different from paper to a paper twisted yarn obtained by twisting a paper tape, and adjust the twisting direction of the paper twisted yarn. Is to obtain a processed twisted yarn by performing reverse twisting in the opposite direction.
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, there can be used, without any particular limitation, a raw material containing fibers collected from the bark of Asa, Kozo, Mitsumata and Ganpi, or a paper obtained by making a raw material containing wood pulp. Although the width of the paper tape is not particularly limited, a width of 1 mm to 5 mm is suitable for a wide range of selection of different material yarns to be twisted. The number of twists (primary twist) when converting the paper tape into a paper twist 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. As the filament yarn, a polyurethane elastic yarn can be used. Examples of other filament yarns include polyester fibers, polyamide fibers, acrylic fibers, polypropylene fibers, and regenerated cellulose fibers (viscose rayon, copper ammonia rayon). The filament yarn may be a monofilament yarn or a multifilament yarn. Further, the filament yarn may be a crimped yarn, and a conjugate yarn or a false twisted yarn can be used as the crimped 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。 The spun yarn as the different material yarn is one or two selected from natural fibers such as cotton, wool, silk, and hemp, polyester fibers, polyamide fibers, acrylic fibers, polypropylene fibers, and cellulose-based regenerated fibers. 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
Reverse twisting is performed in which one or two or more different material yarns selected from these different material yarns are twisted in a direction opposite to the direction of the original twist while being attached to the paper twisted yarn. This reverse twisting is performed by twisting a unit length of paper tape N times into a length L paper twisted yarn by twisting N times with respect to the length L paper twisted yarn so as to satisfy the following relationship. is there.
N × 1.0 <M ≦ N × 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 twisted paper yarn exceeds the state of the number of twists of zero, and is further twisted in a direction opposite to the twisting direction. The dissimilar material yarn that is reverse-twisted with the paper twisted yarn from the state attached to the original twisted paper twisted yarn returns to the original paper tape shape after the number of twists of the paper twisted yarn becomes zero, and further twists in the opposite direction beyond that state When twisted, it is twisted so as to be wrapped inside the paper tape. Therefore, the different material yarn hardly appears on the surface of the processed 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 M of reverse twists per length L of the paper twisted yarn corresponding to the unit length of paper tape exceeds 3.0 times the number of original twists N, the processed twisted yarn is liable to be cut. If the number of times M of the reverse twist is 1.3 times or more and 2.7 times or less of N, it is desirable that the different material yarn is less likely to appear on the surface and the yarn breakage is less likely to occur. If the number M of reverse twists is 1.5 times or more of N, it is more desirable because the different material yarn is less likely to appear on the surface, and if it is 1.8 times or more of N, the different material yarn hardly appears on the surface. It is particularly preferable because it does not appear. On the other hand, if the number of times of this reverse twist is more than 1.0 times N and less than 1.3 times, the different material yarn is less likely to appear on the surface and is close to a non-twisted state, giving a soft texture. It becomes a 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。 Further, as the different material yarn, a water-soluble yarn can be used. Desirably, the water-soluble yarn dissolves without requiring a long time when immersed in water at a temperature lower than the boiling point. Specifically, when the water-soluble yarn alone is immersed in water at a temperature of 90 ° C. and left for 30 minutes, the water-soluble yarn exhibits a water solubility of 85% by mass or more based on the mass of the water-soluble yarn before immersion. It is more preferable that the compound has a water solubility of 95% by mass or more. As such a water-soluble yarn, a fiber composed of a water-soluble polyvinyl alcohol fiber, a water-soluble ethylene-vinyl alcohol copolymer fiber, and a water-soluble polyamide fiber can be used. The water-soluble yarn may be a filament yarn or a 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 yarn is used as a different material yarn, the water-soluble yarn has poor elasticity. When the reverse twist is performed 2N times on the paper twisted yarn having the length L by the unit length paper tape being twisted N times, the paper twisted yarn is twisted N times in the opposite direction to the original twist, When the water-soluble yarn has poor elasticity, 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. The 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 yarn, one or two or more different material yarns that are not water-soluble yarns may be used, only water-soluble yarns may be used, or a water-soluble yarn and a non-water-soluble yarn may be used. One or a combination of two or more of the 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 the present embodiment will be described. In the method for producing a woven or knitted fabric, the processed twisted yarn produced by the method for producing a processed twisted yarn of the above embodiment is used for at least a part of the yarn to be knitted and weaved. Since the tensile strength and the tear strength of the processed twisted yarn are higher than that of the paper twisted yarn due to the presence of the different material yarn, the knitting and weaving are easier than in the case of knitting and weaving only the paper twisted yarn. In addition, the tensile strength and the tear strength of a woven or knitted fabric produced by knitting or weaving a processed twisted yarn are increased as compared with a woven or knitted fabric in which only a paper twisted yarn is knitted or woven.
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, when a yarn having a high elasticity is used as the different material yarn, the elasticity of the processed twisted yarn can be increased more than that of the paper twisted yarn, so that the knitting and weaving can be easily performed as compared with the case where only the paper twisted yarn is knitted and weaved.
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, the reverse twisting of the paper twisted yarn and the dissimilar material yarn makes it difficult for the dissimilar material yarn to appear on the surface of the processed twisted yarn. Thread is difficult to appear. 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 sufficiently exhibits the excellent moisture absorption and moisture release properties of paper can be manufactured. For example, the paper yarn (Oji Fiber Co., Ltd., OJO + (registered trademark), 1515 standard, metric count 1/41) made of Asa as a raw material and the cotton yarn (metric count 20/1) exhibit hygroscopicity and moisture release. In comparison, it is as follows.
<Hygroscopicity>
Paper twist: 11.80%
Cotton thread: 11.90%
<Moisture release>
Paper twist: 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。 That is, the twisted paper yarn has the same level of hygroscopicity as cotton yarn, which is said to be a fiber having high hygroscopicity, and has much higher moisture release (easiness of drying) than cotton yarn. Here, the hygroscopicity is evaluated based on the moisture content after leaving the absolutely dried sample in a constant temperature / humidity space at a temperature of 20 ° C. and a relative humidity of 95% for 60 minutes. The larger the numerical value, the higher the hygroscopicity. The moisture release was evaluated by measuring the mass of a sample completely immersed in water after dehydration, and measuring 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 value, 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 weaving or weaving processed twisted yarns using only water-soluble yarns as different material yarns, or when weaving or weaving processed twisted yarns containing water-soluble yarns in two or more types as different material yarns, Before or after weaving, the water-soluble yarn is dissolved and removed with water. In the processed twisted yarn, the water-soluble yarn twists and shrinks the paper twisted yarn, so when the water-soluble yarn is dissolved and removed from the processed twisted yarn, the force to return to the original state from the contracted state acts on the paper twisted yarn. I do. Therefore, when dissolving and removing the water-soluble yarn before knitting and weaving, the knitting and weaving is facilitated by the elasticity exhibited in the processed twisted yarn, and a woven and knitted material with high elasticity is produced. On the other hand, when dissolving and removing the water-soluble yarn after knitting and weaving, a woven and knitted fabric with high elasticity is produced, and the pores formed after the water-soluble yarn is dissolved have a plump texture. It becomes a highly breathable woven or knitted fabric.
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。 Twisted paper yarn (Oji Fiber Co., Ltd., OJO + (registered trademark), 1515 standard, metric number 1:41, left-handed 500 turns / m), polyethylene-based multifilament yarn (144), 150 denier The twisted yarn of Example S1 was subjected to right twisting (reverse twisting) 1000 times per length of a paper twisting yarn corresponding to a 1 m long paper tape (length when a 1 m long paper tape was left-twisted 500 times). Manufactured. Here, the number of reverse twists is 2.0 times the number of original twists N per length of paper twisted 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.) was added to the same paper twisted yarn (500 twists / m left) as in Example S1, and a 1 m long paper tape was added. The twisted paper yarn of Example S2 was produced by right-hand twisting (reverse twisting) 1000 times per length of the paper twisted 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 (Mintvar (registered trademark), 50 denier, manufactured by Kuraray Trading Co., Ltd.) was added to the same paper-twisted yarn (500 twists / m left-handed) as in Examples S1 and S2, and the length was adjusted. The processed twisted yarn of Example S11 was manufactured by right-hand twisting (reverse twisting) 1000 times per length of the paper twisted yarn corresponding to a 1 m 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 paper twist yarn (left-hand twist 500 times / m) as in Examples S1, S2, and S11, the same polyurethane elastic yarn, 40 denier, 3 filaments as in Example S2, and the same water-soluble polyvinyl alcohol as in Example S11 A processed twisted yarn of Example S12 was produced by adding a water-soluble system yarn and 50 denier and right-twisting (reverse twisting) 1000 times per length of a 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, a twisted yarn of Comparative Example R1 was made of the same paper twist yarn (left-twisted 500 turns / m) as in Examples S1, S2, S11, and S12 but not reverse-twisted with a different material yarn. A spun yarn of 100% cotton (count 1/16) was used as a 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 processed twisted yarn after the reverse twisting with the water-soluble yarn was 87% to 88% of the length of the paper twisted yarn before the start of the reverse twisting, and was greatly twisted and reduced. Was. This was thought to be due to the poor elasticity of the water-soluble yarn. On the other hand, in Example S2, the length of the processed twisted yarn after reverse twisting with the polyurethane elastic yarn was the length of the paper twisted yarn before reverse twisting, that is, Comparative Example R1 not reverse twisted with a different material yarn. Was the same as the length of the paper twisted yarn. This was considered to be because the polyurethane elastic yarn was very rich in elasticity, and the reverse twisting proceeded while the polyurethane elastic yarn was 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 processed twisted yarns of Examples S1, S2, S11, and S12 and the twisted yarns of Comparative Examples R1 and R2 were expanded and contracted in accordance with the elasticity C method specified by JIS L1013 (Testing method for chemical fiber filament yarn, 2010). The sex was evaluated. With respect to the processed twisted yarns of Examples S11 and S12 in which a water-soluble yarn was used as the different material yarn, the water-soluble yarn was dissolved and removed with water, and then the stretchability was evaluated. To dissolve and remove the water-soluble yarn, use a measuring machine with a frame circumference of 1 m, apply an initial load to the processed twisted yarn, create a skein of 10 turns, and wrap the skein around the jig in water at a temperature of 90 ° C ± 2 ° C. After the water-soluble yarn was removed, the processed twisted yarn was washed with warm water, suspended and dried, and then evaluated for elasticity. A nonionic surfactant (Neugen (registered trademark) EA-120, manufactured by Daiichi Kogyo Seiyaku Co., Ltd.) was added to the water in which the processed twisted yarn was immersed so as to have a concentration of 2 g / L. Table 1 shows the stretching / elongation 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 stretch ratio of the paper twisted yarn (Comparative Example R1) is 0.6%, which is smaller than the cotton yarn (Comparative Example R2) of 1.0%, and the stretchability is poor. On the other hand, in the processing twisted yarns of Examples S1 and S2 in which the non-water-soluble yarns were reverse-twisted with different material yarns, the expansion and contraction rates were increased to 1.7% and 2.0%. Further, in the processed twisted yarns of Examples S11 and S12 in which a water-soluble yarn is used as the different material yarn, the stretch ratio is greatly increased to 6.0% and 8.6%. This is because the water-soluble yarn that restrains the state is removed from the paper twisted yarn that has been twisted and shrunk by reverse twisting with the water-soluble yarn with poor elasticity, and the force to return to the original state acts. Then, it is considered that the paper twisted yarn had elasticity.
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, in Example S12 using polyurethane elastic yarn in addition to the water-soluble yarn as the different material yarn, the expansion and contraction rate was greatly increased from Example S11 using only the water-soluble yarn as the different material yarn. I have. This is due to the fact that the water-soluble yarn, which was twisting and shrinking the paper twisted yarn, exhibited elasticity in the paper twisted yarn, and the disappearance of the water-soluble yarn allowed the polyurethane elastic yarn to exhibit its own elasticity more. , And a synergistic effect.
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 / knitted fabric of the embodiment was manufactured by knitting and weaving using the processed twist yarn of Example S12 before removing the water-soluble yarn as the weft yarn and the cotton yarn as the warp yarn. The woven and knitted fabric was made of satin-woven jeans, so that a large amount of weft appeared on the back. In the case of knitting and weaving only the paper twisted yarn, the knitting and weaving was difficult and the yield was about 30%. However, the knitting and weaving of the processed twisted yarn of Example S12 was very smooth, and the yield was 100%. After knitting and weaving, the water-soluble yarn was dissolved and removed from the 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 was very rich in elasticity, and particularly highly elastic in the lateral direction. In addition, the paper was almost completely exposed on the back surface of the jeans cloth, and the paper had a dry and dry feel unique to paper. When jeans (trousers) are made from jeans fabric, the back surface comes into contact with the wearer's skin. Therefore, it is considered that sweat is quickly absorbed by the fabric due to the excellent moisture absorption property of the paper, and is quickly dissipated by the excellent moisture release property of the paper.
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 the preferred embodiments. However, the present invention is not limited to the above embodiments, and various improvements can be made without departing from the gist of the present invention as described below. 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, the case where the processed twisted yarn of Example S12 is knitted and woven and the water-soluble yarn is dissolved and removed after knitting has been described above. It is possible to obtain a woven or knitted fabric with rich properties. In this case, if the water-soluble yarn is removed before weaving, it becomes a highly twisted processed twist yarn, so that weaving can be performed well.
