Description

本発明は、細い繊維を紡績によって束ねて形成される紡績糸の糸継ぎ方法および糸継ぎを含む編地に関する。   The present invention relates to a spun yarn splicing method in which thin fibers are bundled by spinning, and a knitted fabric including the spliced yarn.

従来から、天然繊維や合成繊維などを素材として紡績された編糸や織糸として、編地や織地の形成のために広く用いられている。これらの編糸や織糸は、編成や製織の途中で切れてしまうことがあり、修復のための糸継ぎが必要となる。また、編糸で編地を編成する場合、柄の切換わるタイミングに合わせて異なる編糸への糸継ぎも行われる（たとえば、特許文献１参照）。手袋を編成する際に、色の異なる編糸と糸継ぎを行い、色柄編成を行うことも開示されている（たとえば特許文献２参照）。   2. Description of the Related Art Conventionally, knitting yarns and woven yarns spun from natural fibers or synthetic fibers are widely used for forming knitted fabrics and woven fabrics. These knitting yarns and woven yarns may be cut off during knitting or weaving, and a splicing for repair is required. When a knitted fabric is knitted with knitting yarns, splicing to different knitting yarns is also performed in accordance with the timing of pattern switching (see, for example, Patent Document 1). It is also disclosed that when knitting gloves, knitting yarns with different colors and piecing are performed, and color pattern knitting is performed (for example, see Patent Document 2).

図４は、従来からの糸継ぎの一般的な方法として、異なる糸の端部同士を結び目を形成して継いでいる状態を示す。すなわち糸１と糸２とは、端部に結び目３を形成して糸継ぎが行われる。各糸１，２の先端１ａ，２ａは、結び目３から突出する。先端１ａ，２ａは、結び目３の形成後に切断して短くすることはできるけれども、全く消失させることは困難である。糸１，２が編地を編成する編糸である場合、結び目３を形成するために、ノッター装置が用いられている。また、結び目３を形成して継ぐ方法は、紡績糸ばかりではなく、ロープなどでも広く行われている。   FIG. 4 shows a state in which the ends of different yarns are joined by forming a knot as a general method of conventional yarn splicing. That is, the yarn 1 and the yarn 2 are joined by forming a knot 3 at the end. The ends 1 a and 2 a of the yarns 1 and 2 protrude from the knot 3. Although the tips 1a and 2a can be cut and shortened after the knot 3 is formed, it is difficult to eliminate them at all. When the yarns 1 and 2 are knitting yarns for knitting a knitted fabric, a knotter device is used to form the knot 3. Further, the method of forming and joining the knot 3 is widely performed not only with spun yarn but also with ropes.

図５は、結び目を形成しないで糸継ぎを行う方法による糸１，２の接合状態を示す。この糸継ぎ方法は、糸１，２が紡績糸である場合に有効であり、対向する２本の糸１，２の先端側の繊維の撚りがいったん解けてから相互に絡み合い、外観上「Ｉ」字型の継目４が形成される。なお、各糸１，２の先端１ａ，２ａは、解撚された状態で若干残る。この継目４の形成による糸継ぎは、圧縮空気の噴出などによって迅速に行うことができる（たとえば、特許文献３参照）。   FIG. 5 shows a joined state of the yarns 1 and 2 by a method of piecing without forming a knot. This splicing method is effective when the yarns 1 and 2 are spun yarns. The yarns on the tip side of the two opposing yarns 1 and 2 are entangled with each other. A "-shaped seam 4 is formed. Note that the ends 1a and 2a of the yarns 1 and 2 remain slightly untwisted. Yarn splicing by forming the seam 4 can be performed quickly by jetting compressed air or the like (see, for example, Patent Document 3).

図６は、結び目を形成しないで糸継ぎを行う他の方法を示す。この方法も、糸１，２が紡績糸である場合に有効となる。糸１，２は同方向に先端を向けて並べ、先端同士を絡み合わせて包絡部５を形成する（たとえば、特許文献４参照）。この方法による包絡部５は、外観上「Ｔ」字型となり、「Ｔ」字の縦線に相当する部分が、糸１，２による「Ｔ」字の横線に相当する部分の径方向外方に突出する。この包絡部５の先端には、糸１，２の先端１ａ，２ａが解撚された状態で突出する。特許文献２でも、この糸継ぎ方法が用いられている。   FIG. 6 shows another method for piecing without forming a knot. This method is also effective when the yarns 1 and 2 are spun yarns. The yarns 1 and 2 are arranged with their tips directed in the same direction, and the tips are entangled to form the envelope portion 5 (see, for example, Patent Document 4). The envelope portion 5 by this method has an appearance of “T” shape, and the portion corresponding to the vertical line of “T” is radially outward of the portion corresponding to the horizontal line of “T” formed by the threads 1 and 2. Protrusively. The tips 1a and 2a of the yarns 1 and 2 protrude in the untwisted state at the tip of the envelope portion 5. Patent Document 2 also uses this yarn splicing method.

図４に示すような結び目３を、ノッター装置などで形成しての糸継ぎを編糸に適用すると、結び目３が糸１，２の太さの数倍程度の径となるので、編目形成時に抵抗となったり、編針に引っ掛かり、糸切れを起こすおそれがある。図５に示すような２本の糸１，２が絡み合って形成される継目４では、糸１，２の色が異なる場合、混色が生じ、色境界がはっきりしなくなる。色柄を編成する場合、異なる色の糸１，２を接合した継目４で混色が生じると、意図しない色の部分が生じることとなり、編地の外観を損ってしまう。図６に示すような２本の糸１，２の先端を撚り合わせる方法では、包絡部５の処理が問題となる。包絡部５が編地の外部に突出して見えると、外観を損ってしまう。包絡部５が編地に組込まれた場合、包絡部５と合せて編糸が３本分となる部分が生じてしまう。包絡部５を編地の内部に取込んで隠すことができれば、包絡部５で連結する糸１，２は混色しないで切換り、外観が良好な色柄などを編成することができる。ただし、包絡部５をうまく処理することは困難である。さらに、図５や図６に示す方法では、異なる糸１，２を絡めるので、糸１，２の性質が異なると、組合せを考慮する必要が生じる場合がある。   When a knot 3 as shown in FIG. 4 formed by a knotter device or the like is applied to a knitting yarn, the knot 3 has a diameter that is several times the thickness of the yarns 1 and 2. There is a risk of becoming a resistance or being caught on the knitting needle and causing yarn breakage. In the joint 4 formed by intertwining two yarns 1 and 2 as shown in FIG. 5, when the colors of the yarns 1 and 2 are different, color mixing occurs and the color boundary becomes unclear. When a color pattern is knitted, if color mixing occurs at the joint 4 where the yarns 1 and 2 of different colors are joined, an unintended color portion is generated, and the appearance of the knitted fabric is impaired. In the method of twisting the ends of the two yarns 1 and 2 as shown in FIG. 6, the processing of the envelope portion 5 becomes a problem. If the envelope 5 appears to protrude outside the knitted fabric, the appearance is impaired. When the envelope part 5 is incorporated in the knitted fabric, a part corresponding to three knitting yarns is generated together with the envelope part 5. If the envelope part 5 can be taken into the knitted fabric and concealed, the yarns 1 and 2 connected by the envelope part 5 can be switched without being mixed, and a pattern having a good appearance can be knitted. However, it is difficult to process the envelope part 5 well. Further, in the methods shown in FIGS. 5 and 6, since different yarns 1 and 2 are entangled, there is a case where the combination needs to be considered if the properties of the yarns 1 and 2 are different.

本発明の目的は、糸継ぎの際に結び目を形成しないで、しかも混色や端糸の突出をなくし、品質や外観を向上させることができる紡績糸の糸継ぎ方法および糸継ぎを含む編地

本発明によれば、２本の紡績糸の端部同士を接合する際に、各紡績糸の端部をそれぞれ折返して、折返し部分が相互に結合するように対向させ、各糸の先端側を解撚して、折返し部分の基端側と絡み合わせ、自分自身に絡ませるため、継ぐ相手に関係なく、確実に糸継ぎを行うことができる。素材の性質や太さが異なる相手であっても、容易に継ぐことができる。結び目が形成されないので、編糸では編目形成時に抵抗となったり、編針に引っ掛かり、糸切れを起こすおそれをなくすことができる。各糸は、折返し部分で相互に結合するので、色が異なっても混色しないで品質や外観を向上させることができる。
According to the present invention, in joining the ends of the spun yarn of the two, by folding back the end of each yarn respectively, are opposed to the folded portions are bonded to each other, the tip end of the yarn a and untwisting, move entangled the base end side of the folded portion, regardless of the order Mase fault yourself, take over the other party, surely it is possible to carry out the piecing. Even opponents with different material properties and thickness can be easily inherited. Since the knot is not formed, it is possible to eliminate the possibility that the knitting yarn may become a resistance when forming the stitch, or may be caught by the knitting needle and cause yarn breakage. Since the yarns are bonded to each other at the folded portion, the quality and appearance can be improved without mixing even if the colors are different.

また本発明によれば、色、太さ、形状等の外観が異なる２本の紡績糸を、結び目や混色部分を形成しないで継ぐことができる。

さらに本発明によれば、色柄を形成する編地などで、柄の切り換り部分の編成に、結び目および混色の部分が形成されない糸継ぎを行い、品質や外観の向上した編地を編成することができる。   Furthermore, according to the present invention, in a knitted fabric that forms a colored pattern, the knitted fabric with improved quality and appearance is knitted by knitting a knot and a mixed-color portion in the knitting of the pattern switching portion. can do.

図１は、本発明の実施の一形態で、糸継ぎされる接合部分の形状を示す。糸継ぎ部１０では、２本の紡績糸１１，１２の端部同士を接合する。各紡績糸１１，１２は、先端側１１ａ，１２ａが突合わされるように、相互に逆向きに対向させる。各紡績糸１１，１２の先端側１１ａ，１２ａは、基端側へそれぞれ折返す。紡績糸１１，１２は、折返し部１１ｂ，１２ｂ同士が相互に結合して継がれる。すなわち、紡績糸１１の折返し部１１ｂには紡績糸１２の折返し部１２ｂが貫通し、紡績糸１２の折返し部１２ｂには紡績糸１１の折返し部１１ｂが貫通している。各紡績糸１１，１２の先端側１１ａ，１２ａは解撚され、各折返し部１１ｂ，１２ｂの基端側１１ｃ，１２ｃとそれぞれ絡み合わされて接合される。   FIG. 1 shows a shape of a joint portion to be spliced according to an embodiment of the present invention. In the yarn splicing portion 10, the ends of the two spun yarns 11 and 12 are joined together. The spun yarns 11 and 12 are opposed to each other in opposite directions so that the front end sides 11a and 12a are abutted. The front ends 11a and 12a of the spun yarns 11 and 12 are folded back toward the base end. The spun yarns 11 and 12 are joined by connecting the folded portions 11b and 12b to each other. That is, the folded portion 12 b of the spun yarn 12 passes through the folded portion 11 b of the spun yarn 11, and the folded portion 11 b of the spun yarn 11 passes through the folded portion 12 b of the spun yarn 12. The front ends 11a and 12a of the spun yarns 11 and 12 are untwisted and entangled with and joined to the base ends 11c and 12c of the folded portions 11b and 12b, respectively.

すなわち、２本の紡績糸１１，１２の端部である先端側１１ａ，１２ａ同士を接合するために、各紡績糸１１，１２を、先端側１１ａ，１２ａをそれぞれ、いわば「Ｊ」字状に折返して、折返し部１１ｂ，１２ｂが相互に結合するように対向させ、各紡績糸１１，１２の先端側１１ａ，１２ａを、折返し部１１ｂ，１２ｂの基端側１１ｃ，１２ｃと絡み合わせて、それぞれ接合する。各紡績糸１１，１２の先端側１１ａ，１２ａをそれぞれ折返して、折返し部１１ｂ，１２ｂが相互に結合するように対向させるので、端部同士を糸継ぎの対象とすることができる。各紡績糸１１，１２の先端側１１ａ，１２ａを、折返し部１１ｂ，１２ｂの基端側１１ｃ，１２ｃと絡み合わせて、それぞれ接合するので、各紡績糸１１，１２の先端側１１ａ，１２ａは、折返し部１１ｂ，１２ｂの基端側１１ｃ，１２ｃと絡み合って連結され、自分自身との絡み合いで確実に糸継ぎを行うことができる。結び目が形成されないので、編糸では編目形成時に抵抗となったり、編針に引っ掛かり、糸切れを起こすおそれを抑えることができる。各糸は、折返し部１１ｂ，１２ｂで相互に結合するので、色が異なっても混色しないで品質や外観を向上させることができる。先端側１１ａ，１２ａは基端側１１ｃ，１２ｃに絡み合うので、最先端１１ｄ，１２ｄが毛羽になる程度に抑えることができる。   That is, in order to join the tip end sides 11a and 12a, which are the end portions of the two spun yarns 11 and 12, the spun yarns 11 and 12 have a tip end side 11a and 12a in a so-called "J" shape. Fold back and face each other so that the folded portions 11b and 12b are coupled to each other, entangle the leading ends 11a and 12a of the spun yarns 11 and 12 with the proximal ends 11c and 12c of the folded portions 11b and 12b, respectively. Join. Since the front ends 11a and 12a of the spun yarns 11 and 12 are folded back so as to face each other so that the folded portions 11b and 12b are coupled to each other, the ends can be used as yarn joining targets. Since the front ends 11a and 12a of the spun yarns 11 and 12 are intertwined with the proximal ends 11c and 12c of the folded portions 11b and 12b and joined, respectively, the front ends 11a and 12a of the spun yarns 11 and 12 are The base ends 11c and 12c of the folded portions 11b and 12b are intertwined with each other, and the yarn splicing can be reliably performed by the intertwining with itself. Since the knot is not formed, it is possible to suppress the possibility that the knitting yarn may become a resistance at the time of forming the stitch or may be caught by the knitting needle and cause the yarn to break. Since the yarns are coupled to each other at the turn-back portions 11b and 12b, the quality and appearance can be improved without being mixed even if the colors are different. Since the distal end sides 11a and 12a are entangled with the proximal end sides 11c and 12c, the leading ends 11d and 12d can be suppressed to the extent that they become fluffy.

図２は、図１に示す糸継ぎ部１０を形成しながら編成する編地２０を簡略化して示す。編地２０には、インターシャ編成などによって形成される色柄２１，２２，２３が設けられる。このため、編地２０の地柄を編成する編糸と色柄２１，２２，２３を編成する編糸とを切換えて編成する必要がある。このような色柄２１，２２，２３の編成では、色の異なる編糸毎に異なる給糸部材を使用して行うことができる。また、色柄２１，２２，２３で分けられる編地２０の地柄２０ａ，２０ｂも異なる給糸部材を使用する。したがって、色柄２１，２２，２３と編地２０の地柄２０ａ，２０ｂとを編成するために、５つの給糸部材を使用する。   FIG. 2 shows a simplified knitted fabric 20 that is knitted while forming the spliced portion 10 shown in FIG. The knitted fabric 20 is provided with color patterns 21, 22, and 23 formed by intarsia knitting. For this reason, it is necessary to switch between the knitting yarn for knitting the ground pattern of the knitted fabric 20 and the knitting yarn for knitting the color patterns 21, 22, 23. Such knitting of the color patterns 21, 22, and 23 can be performed by using different yarn supplying members for knitting yarns having different colors. Further, the yarn patterns 20a and 20b of the knitted fabric 20 divided by the color patterns 21, 22, and 23 use different yarn supplying members. Therefore, five yarn supplying members are used for knitting the patterns 21, 22, 23 and the patterns 20a, 20b of the knitted fabric 20.

図１に示すような糸継ぎ部１０を形成して編糸を継ぐようにすれば、１つの給糸部材で、複数の編糸を切換えて色柄２１，２２，２３を編成し、色柄２１，２２，２３の境界を糸継ぎ部１０で継ぐことができる。糸継ぎ部１０では、編糸の色が異なるような場合でも、混色なく色を切換えることもできる。   If the yarn joining portion 10 as shown in FIG. 1 is formed so as to join the knitting yarn, a plurality of knitting yarns are switched by one yarn supplying member to knitted the color patterns 21, 22, and 23. The boundary between 21, 22, and 23 can be joined by the yarn joining portion 10. In the yarn splicing section 10, even when the colors of the knitting yarns are different, the colors can be switched without color mixing.

図３は、図１のような糸継ぎ部１０を形成するための概略的な手順を示す。たとえば、図２で編地２０の地柄と色柄２１，２２とを切換える部分で編成されると予想される編糸が供給されるときに、その供給経路で糸継ぎが行われる。編成の予測は、特許文献１に開示されているように、編成データに基づいて編地２０の編成で消費される編糸の長さをループ長などのデータに基づいて算出し、編糸の供給量を計測して行うことができる。糸継ぎが必要になると、ステップｓ０から糸継ぎを開始する。糸継ぎ前に供給している編糸が未だ充分に残っている場合は切断する。切断の際には、尾端の少し先の部分を保持しておく。ステップｓ１では、糸継ぎを行う編糸の先端側を、切断された編糸の尾端に対向させるようにして、２本の紡績糸を対向させる。ステップｓ２では、２本の紡績糸の先端を折返し、折返し部分同士を結合する。この接合には、特許文献２，３，４で開示されているような圧縮空気流で先端を解撚して包絡させる装置と同様な原理の装置を用いることもできる。ただし、両側で接合を行い、装置へのセットの状態は異ならせる必要がある。次のステップｓ３では、先端側と折返し部の基端側とを接合し、ステップｓ４で手順を終了する。   FIG. 3 shows a schematic procedure for forming the yarn splicing portion 10 as shown in FIG. For example, when a knitting yarn which is expected to be knitted at a portion where the pattern of the knitted fabric 20 and the color patterns 21 and 22 are switched in FIG. As disclosed in Patent Document 1, the knitting prediction is performed by calculating the length of the knitting yarn consumed in the knitting of the knitted fabric 20 based on the knitting data based on the data such as the loop length. This can be done by measuring the supply amount. When the yarn joining is necessary, the yarn joining is started from step s0. If there is still enough knitting yarn supplied before splicing, cut. At the time of cutting, hold the part slightly ahead of the tail end. In step s1, the two spun yarns are opposed so that the leading end side of the knitting yarn to be spliced is opposed to the tail end of the cut knitting yarn. In step s2, the ends of the two spun yarns are folded back and the folded portions are joined together. For this joining, a device having the same principle as that of a device for unwinding and enveloping the tip with a compressed air flow as disclosed in Patent Documents 2, 3, and 4 can be used. However, it is necessary to perform bonding on both sides and to change the state of the set to the device. In the next step s3, the distal end side and the proximal end side of the folded portion are joined, and the procedure ends in step s4.

なお、ステップｓ２では２本の紡績糸１１，１２の先端側１１ａ，１２ａの折返しと結合とを同時に行い、ステップｓ３では先端側１１ａ，１２ａの基端側１１ｃ，１２ｃへの接合を同時に行っているけれども、別に行うこともできる。すなわち、一方の糸１１の先端側１１ａを折返し部１１ｂの基端側１１ｃに先に接合しておく。折返し部１１ｂは、輪状になっているので、この輪状の中に他方の糸１２の先端側１２ａを挿入して折返し、折返し部１２ｂを形成するとともに、先端側１２ａを折返し部１２ｂの基端側１２ｃともに接合するようにすればよい。片側ずつ接合するので、特許文献２，３，４で開示されている装置を直接使用することもできる。   In step s2, the front ends 11a and 12a of the two spun yarns 11 and 12 are folded and joined simultaneously, and in step s3, the tips 11a and 12a are joined to the base ends 11c and 12c at the same time. Yes, but you can do it separately. That is, the front end side 11a of one thread 11 is first joined to the proximal end side 11c of the folded portion 11b. Since the folded portion 11b has a ring shape, the distal end side 12a of the other thread 12 is inserted into the loop shape to be folded to form the folded portion 12b, and the distal end side 12a is the base end side of the folded portion 12b. What is necessary is just to join together 12c. Since the bonding is performed one side at a time, the devices disclosed in Patent Documents 2, 3, and 4 can be used directly.

また、糸継ぎ部１０を形成して切換える２本の紡績糸１１，１２は、色や他の外観など、外観が異なれば、境界がはっきりする効果を奏することができる。色柄２１，２２，２３を形成する編地２０ばかりではなく、編糸の太さが変化する編地や、編糸の毛羽などが変化する編地を、境界をはっきりさせ、しかも結び目が形成されない糸継ぎを行って、品質や外観の向上させて編成することができる。さらに、編地を編成する場合、編糸の切換えを、使用可能な給糸部材の数などで制限されないので、多くの色を使い分けるなどで、商品価値を高めた編地を編成することもできる。   In addition, the two spun yarns 11 and 12 that are switched by forming the yarn splicing portion 10 can exhibit an effect that the boundary is clear if the appearance is different such as color or other appearance. Not only the knitted fabric 20 that forms the color patterns 21, 22, and 23, but also the knitted fabric in which the thickness of the knitting yarn changes, and the knitted fabric in which the fluff of the knitting yarn changes, and the knot is formed. It is possible to perform knitting with improved quality and appearance by performing splicing that is not performed. Furthermore, when knitting a knitted fabric, the switching of the knitting yarn is not limited by the number of yarn supplying members that can be used, so it is also possible to knitted a knitted fabric with an increased commercial value by using many colors. .

本発明の実施の一形態で、糸継ぎされる接合部分の形状を簡略化して示す図である。FIG. 3 is a diagram showing a simplified shape of a joining portion to be spliced according to an embodiment of the present invention. 図１に示す糸継ぎ部１０を形成しながら編成する編地２０を簡略化して示す図である。It is a figure which simplifies and shows the knitted fabric 20 knitted while forming the yarn splicing part 10 shown in FIG. 図１のような糸継ぎ部１０を形成するための概略的な手順を示す工程図である。It is process drawing which shows the schematic procedure for forming the yarn splicing part 10 like FIG. 従来からの糸継ぎの一般的な方法として、異なる糸の端部同士を結び目を形成して継いでいる状態を簡略化して示す図である。It is a figure which simplifies and shows the state which forms the knot and joins the edge parts of a different thread | yarn as a general method of the conventional yarn splicing. 先行技術による結び目を形成しないで糸継ぎを行う方法での糸１，２の接合状態を簡略化して示す図である。It is a figure which simplifies and shows the joining state of the threads | yarns 1 and 2 by the method of piecing without forming the knot by a prior art. 先行技術による結び目を形成しないで糸継ぎを行う他の方法を簡略化して示す図である。It is a figure which simplifies and shows the other method of performing a yarn splicing, without forming the knot by a prior art.
