Description
この発明は、厚みのある立体筒状編地を無縫製で編成することに関する。 The present invention relates to knitting a thick three-dimensional cylindrical knitted fabric without sewing.
表編地と裏編地との間に、弾性がある連結糸をタック等により充填し、あるいはウーリーナイロン等の柔らかい糸をミス等で充填した立体編地が知られている（特許文献１：特開2004-107800）。このような立体編地は厚く、充填する糸の剛性により硬さを制御でき、耐熱性の糸を選ぶことにより断熱材として使用できる。立体編地は例えばパイプ及びケーブルの保護に用いられ、平面状の立体編地を切断し、縫製によって切断面を閉じて、パイプあるいはケーブルに巻き付けて使用する。しかしながらパイプあるいはケーブル等の外形に合わせて、元々平面状の立体編地を曲げることは難しく、また切断と縫製の手間もかかる。 There is known a three-dimensional knitted fabric in which an elastic connecting yarn is filled with a tuck or the like between a front knitted fabric and a back knitted fabric, or a soft yarn such as wooly nylon is filled with a mistake or the like (Patent Document 1: JP 2004-107800). Such a three-dimensional knitted fabric is thick, the hardness can be controlled by the rigidity of the yarn to be filled, and it can be used as a heat insulating material by selecting a heat-resistant yarn. The three-dimensional knitted fabric is used, for example, for protecting pipes and cables. A flat three-dimensional knitted fabric is cut, and the cut surface is closed by sewing, and then wound around a pipe or cable. However, it is difficult to bend an originally flat three-dimensional knitted fabric according to the outer shape of a pipe or a cable, and it takes time and labor for cutting and sewing.
この発明の課題は、対象物の外形にフィットし、かつ縫製及び切断の手間がない立体筒状編地を提供することにある。
この発明の他の課題は、このような立体筒状編地の編成方法を提供することにある。
この発明の他の課題は、配管を効率的に断熱できる立体筒状編地を提供することにある。
The subject of this invention is providing the solid cylindrical knitted fabric which fits the external shape of a target object, and does not have the effort of sewing and a cutting | disconnection.
Another object of the present invention is to provide a knitting method for such a three-dimensional tubular knitted fabric.
Another object of the present invention is to provide a three-dimensional cylindrical knitted fabric capable of efficiently insulating pipes.
この発明の立体筒状編地は、無縫製で筒状の外編地と無縫製で筒状の内編地と、前記外編地と前記内編地との間に充填されかつ前記外編地と前記内編地とに連結された充填糸とからなり、
前記内編地で対象物を覆うように対象物に被せる立体筒状編地で、
前記外編地と前記内編地とが同芯に曲げもしくは径が拡縮されることにより、対象物の形状に合わせて成型され、
かつ少なくとも内編地と充填糸、より好ましくは内編地及び外編地と充填糸とが耐熱糸で構成され、立体筒状編地はパイプ状の対象物の断熱用である。
The three-dimensional tubular knitted fabric of the present invention is filled between the outer knitted fabric and the inner knitted fabric, and the outer knitted fabric and the inner knitted fabric without sewing and the tubular inner knitted fabric without sewing. Consisting of filled yarn connected to the inner knitted fabric,
In the three-dimensional cylindrical knitted fabric that covers the object so as to cover the object with the inner knitted fabric,
The outer knitted fabric and the inner knitted fabric are bent or concentrated to expand and contract the diameter, and are molded according to the shape of the object ,
At least the inner knitted fabric and the filling yarn, more preferably the inner knitted fabric and the outer knitted fabric and the filling yarn are made of heat-resistant yarn, and the three-dimensional cylindrical knitted fabric is for heat insulation of the pipe-shaped object.
この発明では、対象物の外形にフィットする立体筒状編地を提供でき、平面状の立体編地を切断、縫製し、巻き付ける必要がない。 In the present invention, a three-dimensional cylindrical knitted fabric that fits the outer shape of the object can be provided, and there is no need to cut, sew, and wrap a planar three-dimensional knitted fabric.
好ましくは、成型が引き返し編みにより行われている。引き返しにより立体筒状編地を対象物の外形に合わせた立体形状に編成できる。引き返しでは立体筒状編地の所望の位置に所望の目数だけ、他の位置よりも編目を増すことができる。例えば図５，図６のように、筒状編地の一部のエリアのみを編成し、他のエリアでは編目を針に係止したままにして編成を停止し、次いで筒状編地の全体に対して編成を再開する。すると曲がった立体筒状編地を編成できる。また引き返しにより例えば図１０のように編成すると、突起の有る立体筒状編地を編成できる。引き返し以外にも、増目と減らし目とにより立体筒状編地の径を変更できるので、立体筒状編地は、曲げと径の拡縮、突起の形成等ができる。従って大部分の対象物の外形にフィットする立体筒状編地が得られる。立体筒状編地の成型は、場所に応じて編目のサイズを変えること、一部の位置でミスにより編目を編成しないスムース編みと通常の編み方とを使い分けることにより、編目数を場所により変えることでも達成できる。ただし編目のサイズを場所により変えると、糸がコース方向に流れることにより、使用により編目のサイズが均一に近づく可能性がある。またスムース編みよりも引き返しによる編地の方が、一般に強度が高い。 Preferably, the molding is performed by turn knitting. By turning back, the three-dimensional cylindrical knitted fabric can be knitted into a three-dimensional shape that matches the outer shape of the object. By turning back, it is possible to increase the number of stitches at a desired position of the three-dimensional cylindrical knitted fabric by a desired number of stitches compared to other positions. For example, as shown in FIGS. 5 and 6, only a part of the tubular knitted fabric is knitted, and in other areas, the knitting is stopped with the stitches held on the needles, and then the entire tubular knitted fabric is stopped. Resume organization for. Then, a bent solid tubular knitted fabric can be knitted. Further, by knitting as shown in FIG. 10 by turning back, a three-dimensional cylindrical knitted fabric with protrusions can be knitted. In addition to turning back, the diameter of the three-dimensional cylindrical knitted fabric can be changed by increasing and decreasing the number of stitches. Therefore, the three-dimensional cylindrical knitted fabric can be bent and expanded / contracted in diameter and formed with protrusions. Therefore, a three-dimensional cylindrical knitted fabric that fits the outer shape of most objects is obtained. Three-dimensional cylindrical knitted fabric is molded by changing the number of stitches depending on the location by changing the size of the stitch depending on the location, and using smooth knitting that does not knitting stitches due to mistakes at some positions and normal knitting methods. Can also be achieved. However, if the size of the stitch is changed depending on the location, the yarn may flow in the course direction, so that there is a possibility that the size of the stitch will approach evenly by use. Further, the knitted fabric by turning back is generally stronger than the smooth knitting.
この発明の立体筒状編地の編成方法では、少なくとも前後一対の向かい合った針床を備え、前後一対の針床の一方が他方に対してラッキング自在で、前後一対の針床間で編地の受け渡しが自在で、かつ前後一対の針床の間のスペースをトリックギャップとする横編機により、
一方の針床で外編地と内編地とを、内編地が外編地よりもトリックギャップ寄りに位置するように保持し、
他方の針床で外編地と内編地とを、内編地が外編地よりもトリックギャップ寄りに位置するように保持し、
一方の針床に属する外編地と他方の針床に属する外編地とを端部で連結することにより、筒状の外編地を構成し、
一方の針床に属する内編地と他方の針床に属する内編地とを端部で連結することにより、筒状の内編地を構成し、
一方の針床と他方の針床の双方で内編地を編成すると共に、
一方の針床に属する内編地を他方の針床に移動させた状態で、一方の針床に属する外編地を編成すると共に、一方の針床に属する外編地と他方の針床に移動させた内編地とを連結するように、一方の針床に属する外編地と他方の針床に移動させた内編地間に充填糸を充填し、
他方の針床に属する内編地を一方の針床に移動させた状態で、他方の針床に属する外編地を編成すると共に、他方の針床に属する外編地と一方の針床に移動させた内編地とを連結するように、他方の針床に属する外編地と一方の針床に移動させた内編地間に充填糸を充填することにより、無縫製の筒状編地を編成し、
かつ一方の内編地及び外編地と、他方の内編地及び外編地との間で、筒状編地の丈方向の長さを異ならせるように成型編成することにより、丈方向の長さが短い側が内側となるように筒状編地を曲げる。なお丈は、横編機で編成する際に針床に直角な方向で、立体筒状編地の軸方向でもある。
In the knitting method of the three-dimensional cylindrical knitted fabric of the present invention, at least a pair of front and back needle beds are provided, one of the front and back needle beds is rackable with respect to the other, and the knitted fabric is knitted between the pair of front and back needle beds. With a flat knitting machine that can be handed over and the space between a pair of front and back needle beds is a trick gap,
Hold the outer knitted fabric and the inner knitted fabric with one needle bed so that the inner knitted fabric is located closer to the trick gap than the outer knitted fabric,
Hold the outer knitted fabric and the inner knitted fabric with the other needle bed so that the inner knitted fabric is located closer to the trick gap than the outer knitted fabric,
By connecting the outer knitted fabric belonging to one needle bed and the outer knitted fabric belonging to the other needle bed at the end portion, a cylindrical outer knitted fabric is constituted,
By connecting the inner knitted fabric belonging to one needle bed and the inner knitted fabric belonging to the other needle bed at the end, a cylindrical inner knitted fabric is constituted,
While knitting the inner knitted fabric with both one needle bed and the other needle bed,
With the inner knitted fabric belonging to one needle bed moved to the other needle bed, the outer knitted fabric belonging to one needle bed is knitted and moved to the outer knitted fabric belonging to one needle bed and the other needle bed. Filling the filler yarn between the outer knitted fabric belonging to one needle bed and the inner knitted fabric moved to the other needle bed so as to connect the inner knitted fabric,
While the inner knitted fabric belonging to the other needle bed is moved to one needle bed, the outer knitted fabric belonging to the other needle bed is knitted and moved to the outer knitted fabric belonging to the other needle bed and one needle bed. A non-sewn tubular knitted fabric is knitted by filling the filling yarn between the outer knitted fabric belonging to the other needle bed and the inner knitted fabric moved to one needle bed so as to connect the inner knitted fabric. And
In addition, the length in the length direction is formed by knitting so that the length in the length direction of the tubular knitted fabric is different between the one inner knitted fabric and the outer knitted fabric and the other inner knitted fabric and the outer knitted fabric. Bend the tubular knitted fabric so that the short side is the inside. The length is a direction perpendicular to the needle bed when knitting with a flat knitting machine, and is also an axial direction of the three-dimensional cylindrical knitted fabric.

A three-dimensional cylindrical knitted fabric can be knitted in accordance with the outer shape of.
この発明の立体筒状編地は、パイプの断熱、保温、ケーブルの保護、家具、スポーツウェア等に用いることができるが、ボイラーからの配管、冷媒の配管等の配管のカバーとすると、曲がった形状の配管等に容易に被せることができ、テープ状の編地を巻き付けるのでないので、隙間がなく、断熱性が高い。また最初から配管の外形にフィットとする形状なので、平面状の立体編地を切断及び縫製する手間が不要である。 The three-dimensional tubular knitted fabric of the present invention can be used for heat insulation of pipes, heat insulation, cable protection, furniture, sportswear, etc., but when bent as a cover of piping such as piping from a boiler, piping for refrigerant, etc. Since it can be easily put on a pipe having a shape and does not wind a tape-shaped knitted fabric, there is no gap and heat insulation is high. Moreover, since it is a shape that fits the outer shape of the pipe from the beginning, there is no need to cut and sew a planar solid knitted fabric.
以下に、発明を実施するための最適実施例を示す。この発明の範囲は、特許請求の範囲の記載に、周知技術による変更の可能性を加味して解釈されるべきである。 In the following, an optimum embodiment for carrying out the invention will be shown. The scope of the present invention should be construed in consideration of the possibility of modification by well-known techniques in the description of the scope of claims.
図１〜図１０に、実施例を示す。図１は立体筒状編地の編成方法を成型を除いて示し、２は前外編地、４は前内編地で、これらは横編機の例えば前針床に係止されている。６は後外編地、８は後内編地で、これらは横編機の例えば後針床に係止されている。内編地４，８は外編地２，６に対し、針床間のトリックギャップ側、即ち針床間のスペース側に配置され、前外編地２と前内編地４，並びに後外編地６と後内編地８とは、連結糸１０でタックあるいは通常の編目等により連結されている。そして前外編地２と後外編地６は編幅の端部で接続されて外側の筒状編地を構成し、前内編地４と後内編地８も編幅の端部で接続されて内側の筒状編地を構成する。また外側の筒状編地と内側の筒状編地の間に連結糸１０が充填され、かつ外側の筒状編地と内側の筒状編地は連結糸１０で連結されている。 An example is shown in FIGS. FIG. 1 shows a knitting method of a three-dimensional cylindrical knitted fabric excluding molding, 2 is a front outer knitted fabric, 4 is a front inner knitted fabric, and these are locked to, for example, a front needle bed of a flat knitting machine. Reference numeral 6 denotes a rear outer knitted fabric, and reference numeral 8 denotes a rear inner knitted fabric, which are locked to, for example, a rear needle bed of a flat knitting machine. The inner knitted fabrics 4 and 8 are arranged on the trick gap side between the needle beds, that is, on the space side between the needle beds with respect to the outer knitted fabrics 2 and 6, and the front outer knitted fabric 2, the front inner knitted fabric 4, and the rear outer knitted fabric 6 are arranged. The back inner knitted fabric 8 is connected to the back inner knitted fabric 8 with a connecting yarn 10 by a tack or a normal stitch. The front outer knitted fabric 2 and the rear outer knitted fabric 6 are connected at the end of the knitting width to form an outer tubular knitted fabric, and the front inner knitted fabric 4 and the rear inner knitted fabric 8 are also connected at the end of the knitting width. To form an inner tubular knitted fabric. The connecting yarn 10 is filled between the outer cylindrical knitted fabric and the inner cylindrical knitted fabric, and the outer cylindrical knitted fabric and the inner cylindrical knitted fabric are connected by the connecting yarn 10.
編地の糸の材質は用途に応じて定め、例えば配管のカバーなどのように断熱用の場合、編地を構成する糸にはアラミドなどの耐熱性繊維を用いる。一般に内編地４，８は高温のパイプなどに接触し、外編地２，６は空気などに曝されるので、外編地２，６を構成する糸は内編地４，８を構成する糸及び連結糸１０よりも耐熱性が低いものでもよい。連結糸１０は例えばモノフィラメントのアラミド糸などから成り、耐熱性の連結糸１０は立体筒状編地に対して径方向の厚さと強度及び断熱性を与える。耐熱糸以外の糸で外編地と内編地とを構成し、ウーリーナイロン（マルチフィラメントのナイロン糸）等の耐熱繊維以外の連結糸１０を用いると、厚さと弾力性と断熱性とがある立体筒状編地が得られる。このような立体筒状編地は、ケーブルの保護カバー、パイプの保温あるいは凍結の防止用のカバー、家具、衣類などに立体筒状編地を用いる際に適している。 The material of the yarn of the knitted fabric is determined according to the use. For example, in the case of heat insulation such as a pipe cover, a heat-resistant fiber such as aramid is used for the yarn constituting the knitted fabric. In general, the inner knitted fabrics 4 and 8 are in contact with a high-temperature pipe and the like, and the outer knitted fabrics 2 and 6 are exposed to air. Therefore, the yarns constituting the outer knitted fabrics 2 and 6 are yarns constituting the inner knitted fabrics 4 and 8. The heat resistance may be lower than that of the connecting yarn 10. The connecting yarn 10 is made of, for example, a monofilament aramid yarn or the like, and the heat-resistant connecting yarn 10 gives radial thickness, strength, and heat insulation to the three-dimensional cylindrical knitted fabric. When the outer knitted fabric and the inner knitted fabric are composed of yarns other than heat-resistant yarn, and the connecting yarn 10 other than heat-resistant fibers such as wooly nylon (multi-filament nylon yarn) is used, a three-dimensional material having thickness, elasticity, and heat insulation properties. A tubular knitted fabric is obtained. Such a three-dimensional cylindrical knitted fabric is suitable when a three-dimensional cylindrical knitted fabric is used for a cable protective cover, a pipe heat insulating cover or a cover for preventing freezing, furniture, clothing, and the like.
立体筒状編地の編成では、編地２〜８から成る４層の編地を編成し、前外編地２と前内編地４、後外編地６と後内編地８に連結糸１０をタック等で接続する。図１a)は中立状態で、例えば前針床側に前外編地２と前内編地４とが係止され、後針床側に後外編地６と後内編地８とが係止されている。そしてここで内編地４，８は外編地２，６よりもトリックギャップ側に配置され、この状態で内編地４，８を編成することができる。連結糸１０は例えばタックなどにより数目置きに内編地４，８と外編地２，６とを接続し、タックに代えて一部の位置でのみ編目を形成し、他の位置ではミスすることにより、連結糸１０を編地２〜８に接続してもよい。 In the knitting of the three-dimensional cylindrical knitted fabric, four layers of knitted fabric composed of the knitted fabrics 2 to 8 are knitted, and the connecting yarn 10 is connected to the front outer knitted fabric 2 and the front inner knitted fabric 4, and the rear outer knitted fabric 6 and the rear inner knitted fabric 8. Connect with a tack or the like. FIG. 1a) is a neutral state, for example, the front outer knitted fabric 2 and the front inner knitted fabric 4 are locked on the front needle bed side, and the rear outer knitted fabric 6 and the rear inner knitted fabric 8 are locked on the rear needle bed side. ing. Here, the inner knitted fabrics 4 and 8 are arranged closer to the trick gap than the outer knitted fabrics 2 and 6, and the inner knitted fabrics 4 and 8 can be knitted in this state. The connecting yarn 10 connects the inner knitted fabrics 4 and 8 and the outer knitted fabrics 2 and 6 every several stitches by, for example, a tack, forms stitches only at some positions instead of the tack, and misses at other positions. Thus, the connecting yarn 10 may be connected to the knitted fabrics 2 to 8.
図１b)では、後内編地８が前針床側に移動させられており、この状態で後外編地６を編成できる。また図１b)では、後外編地６と後内編地８間に連結糸１０をタックなどで充填できる。図１c)は図１a)と同じ状態を表し、後内編地８が後針床側に移動している。この状態で前内編地４と後内編地８とを編成できる。図１d)では、前内編地４を後針床側に移動させ、この状態で前外編地２を編成すると共に、編地２，４間に連結糸１０をタックなどで充填する。内編地４，８は図１a)または図１c)の状態の時に編成できる。 In FIG. 1b), the rear inner knitted fabric 8 is moved to the front needle bed side, and the rear outer knitted fabric 6 can be knitted in this state. Further, in FIG. 1b), the connecting yarn 10 can be filled between the rear outer knitted fabric 6 and the rear inner knitted fabric 8 with a tack or the like. FIG. 1c) shows the same state as FIG. 1a), and the rear inner knitted fabric 8 has moved to the rear needle bed side. In this state, the front inner knitted fabric 4 and the rear inner knitted fabric 8 can be knitted. In FIG. 1d), the front inner knitted fabric 4 is moved to the rear needle bed side, the front outer knitted fabric 2 is knitted in this state, and the connecting yarn 10 is filled between the knitted fabrics 2 and 4 with tack or the like. The inner knitted fabrics 4, 8 can be knitted when in the state of FIG. 1a) or FIG. 1c).
図２は横編機１２を模式的に示し、前針床１４と後針床１５とを備え、ラッキングモータ１６から延びるネジ棒１８と軸受２０とにより、一方の針床を他方の針床に対し、図２の左右方向に移動できる。２２はキャリッジで、針床１４，１５の針を操作し、編成並びに目移しなどを行う。ここでは２枚の針床１４，１５を備えるものを示したが、４枚の針床を備えるものでもよい。そして横編機１２を用いることの利点は、立体筒状編地を成型編みできる点である。 FIG. 2 schematically shows the flat knitting machine 12, which includes a front needle bed 14 and a rear needle bed 15, and a needle bar 18 and a bearing 20 extending from the racking motor 16, and one needle bed is used as the other needle bed. On the other hand, it can move in the left-right direction in FIG. A carriage 22 operates the needles of the needle beds 14 and 15 to perform knitting and transfer. Here, although the one provided with two needle beds 14 and 15 is shown, it may be provided with four needle beds. The advantage of using the flat knitting machine 12 is that a three-dimensional cylindrical knitted fabric can be molded and knitted.
図３に配管のカバー用の立体筒状編地の例を示し、両端の黒い部分は編始めと編終わりとの部分で、これらの部分を取り外して中間の白い筒を配管カバーとする。立体筒状編地は曲がっており、配管の外形に合わせた形状をしている。配管は高温あるいは低温の流体が流れる管であることが好ましい。 FIG. 3 shows an example of a three-dimensional cylindrical knitted fabric for piping cover. The black portions at both ends are the knitting start and knitting end portions, and these portions are removed and the intermediate white tube is used as the piping cover. The three-dimensional cylindrical knitted fabric is bent and has a shape that matches the outer shape of the pipe. The pipe is preferably a pipe through which a high-temperature or low-temperature fluid flows.
図４，図５に図３の立体筒状編地の編成原理を示す。図４に示すように、立体筒状編地３０の芯に沿った長さが、一方でＬi、他方でＬoであり、ＬoがＬiよりも大きいとする。すると立体筒状編地３０は長さが短い側を内側として曲がろうとし、この結果、図３の形状となる。そして図４の立体編地３０を編成するには、図５のように最初に左右両端で互いに連結されたエリア３１，３２を編成し、次いで引き返しでエリア３３，３４，３６を編成する。この時、線分３５の部分では、編目を針に係止したまま、編成を停止している。次いでエリア３７，３８を編成する。線分３９に沿った編目は針床の針に係止されており、線分３９の編目の次に線分４０の編目を編成し、線分３９，４０は互いに接続されている。また線分４１の編目の次に線分４２の編目を編成し、線分４１，４２も互いに接続されている。すると図５の左側に示すように、筒状エリア４５，４６，４７から成り、曲がった立体筒状編地が得られる。 4 and 5 show the knitting principle of the three-dimensional cylindrical knitted fabric of FIG. As shown in FIG. 4, it is assumed that the length along the core of the three-dimensional cylindrical knitted fabric 30 is Li on the one hand and Lo on the other hand, and Lo is larger than Li. Then, the three-dimensional tubular knitted fabric 30 tries to bend with the short side as the inner side, and as a result, the shape shown in FIG. 3 is obtained. In order to knit the three-dimensional knitted fabric 30 shown in FIG. 4, the areas 31 and 32 connected to each other at the left and right ends are first knitted as shown in FIG. 5, and then the areas 33, 34, and 36 are knitted by turning back. At this time, in the portion of the line segment 35, the knitting is stopped while the stitch is locked to the needle. Next, the areas 37 and 38 are knitted. The stitches along the line segment 39 are locked to the needles on the needle bed, the stitches of the line segment 40 are knitted next to the stitches of the line segment 39, and the line segments 39, 40 are connected to each other. Further, the stitch of the line segment 42 is knitted next to the stitch of the line segment 41, and the line segments 41 and 42 are also connected to each other. Then, as shown on the left side of FIG. 5, a curved solid tubular knitted fabric consisting of tubular areas 45, 46 and 47 is obtained.
図４の立体編地３０は、図６のようにしても編成できる。前後双方の針床により筒状エリア５０，５１，５２を編成し、ここでエリア５１を引き返しで編成し、線分５３の編目の次に線分５４の編目が編成されて、線分５３，５４の間の隙間は塞がれる。そして図６の左端側で丈が右端側よりも短く、編成された立体筒状編地は左端側が内、右端側が外となるように曲がる。 The three-dimensional knitted fabric 30 shown in FIG. 4 can be knitted as shown in FIG. The cylindrical areas 50, 51, 52 are knitted by both the front and back needle beds, the area 51 is knitted by turning back, the stitches of the line segment 54 are knitted next to the stitches of the line segment 53, and the line segments 53, The gap between 54 is closed. And the length is shorter on the left end side in FIG. 6 than on the right end side, and the knitted three-dimensional cylindrical knitted fabric is bent so that the left end side is inward and the right end side is outward.
編地の長さを変化させるためには、一方と他方とで編目のサイズを変える、一方でスムース編を行うことにより編目の数を減らし、他方では天竺編などによりより多い編目を形成する、一方と他方とで糸の材質を変え、例えば曲がって内側となる側を熱収縮性の糸で編成するなども考えられる。なお熱収縮糸を用いる場合、編成後に加熱して糸を収縮させる。しかし最も簡単かつ確実なのは引き返し編みである。 In order to change the length of the knitted fabric, the size of the stitches is changed between one and the other, while the number of stitches is reduced by performing smooth knitting on the one hand, and more stitches are formed on the other hand, such as by a tentacle knitting, It is also conceivable to change the material of the yarn between one and the other, for example, knitting the inner side with a heat-shrinkable yarn. When heat shrink yarn is used, the yarn is shrunk by heating after knitting. But the simplest and most reliable is turnback knitting.
立体筒状編地の径は編成の途中で変更できる。このような例を図７，図８に示し、立体筒状編地７０を編成する間に増目により編幅を増し、次いで減らし目により編幅を元の値に戻すと、途中で径が変化する立体筒状編地が編成できる。増目減らし目を引き返し編みと組み合わせると、曲げ、突起、径の拡縮のある立体筒状編地を編成できる。 The diameter of the three-dimensional cylindrical knitted fabric can be changed during knitting. Such an example is shown in FIGS. 7 and 8, and when the three-dimensional tubular knitted fabric 70 is knitted, the knitting width is increased by increasing the stitches, and then the knitting width is returned to the original value by the decreasing stitches. A changing three-dimensional cylindrical knitted fabric can be knitted. Combined with turn knitting and back knitting, a three-dimensional tubular knitted fabric with bending, protrusions, and diameter expansion / contraction can be knitted.
