Description

  The present invention relates to a knitted fabric knitted by a Raschel knitting machine using three sheets of ground.

Conventionally, a knitted fabric in which warp insertion yarns having various functions and decorative properties are knitted using a warp knitting machine has been developed. For example, Patent Document 1 describes that a reflective material is sandwiched between a tricot knitting yarn and a weft insertion yarn and knitted in a main portion of a warp knitting tape for a reflective slide fastener. In Patent Document 2, in a light-reflective warp knitted fabric, a light-reflective yarn is inserted between a plurality of mesh knitting yarns and a presser yarn, and the light-reflective yarn is exposed on the surface of the mesh hole. The points appearing in are described. Patent Document 3 describes that in a curtain lace where ultraviolet rays are cut, a metal-deposited film yarn is inserted between the ground yarns of the lace.

  In Patent Document 1 described above, since the tricot knitting is used, the density of the knitting yarn that sandwiches the reflective material that is the warp insertion yarn becomes high, and the warp insertion yarn is hidden by the knitting yarn. In Patent Document 2, although the light-reflective yarn, which is a warp insertion yarn, is held in a sufficiently exposed state, five pieces of ground are used in a normal Raschel machine with six pieces of ground, You must use the earth. Further, in Patent Document 3, the metal vapor-deposited yarn is held by entwining two ground yarns with warp yarns forming a chain knit, and at least four pieces of ground are required.

  Also, conventionally, using a jacquard handle on a three-sheet type of jacquard raschel machine, pressing a straight warp yarn while knitting the jacquard pattern, the same as on a four-sheet type Although the effect has been obtained, the yarn used for the handle is usually processed yarn, and since the yarn is used to knit the handle, strong tension is not applied and the tension is not uniform. In addition, the jacquard yarn needs to be swayed frequently to hold down the warp insertion yarn, so the jacquard pattern can be restricted and it is difficult to express the original free pattern. there were.

  Accordingly, an object of the present invention is to provide a knitted fabric that can hold a warp insertion yarn in a stable state and can be sufficiently exposed to the surface by using a Raschel knitting machine using three sheets of ground. It is what.

  A knitted fabric according to the present invention is a knitted fabric knitted by a Raschel knitting machine using three sheets of ground fabric, and is knitted in the warp direction adjacent to the warp insertion yarn extending in the warp direction. And a stitch row knitted by alternately chain-knitting a plurality of knitting yarns for each predetermined length, and a ground yarn alternately knitted into the plurality of stitch rows at a predetermined interval, The knitting yarn is swung in the weft direction between the stitch rows and is in contact with one side of the warp insertion yarn, and the ground yarn is swung in the weft direction between the stitch rows and the warp insertion. It is in contact with the other side of the yarn. Furthermore, the jacquard pattern is knitted on one side.

  By having the above-described configuration, the warp insertion yarn is held from both sides by the knitting yarn and the ground yarn constituting the stitch row, and is thus held in a stable state. Further, by providing an interval in which the knitting yarn is swung in the weft direction, the warp insertion yarn can be sufficiently exposed on the surface. The interval of the knitting yarns swung in the weft direction can be easily adjusted by the length of the chain stitch constituting the stitch row. Therefore, the warp insertion yarn can be held in a stable state and can be sufficiently exposed by only three grounds.

  Even when adding jacquard pattern ridges, the warp insertion yarn is held in the ground structure in a stable state, so the jacquard pattern can be knitted into the ground structure without any restrictions, and the number of sheets can be reduced. This makes it possible to manufacture a knitted fabric with a patterned pattern with a paddle and to reduce costs.

  Hereinafter, embodiments according to the present invention will be described in detail. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention clearly indicates that the invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 schematically shows a plan view of a knitting structure relating to an embodiment according to the present invention, and FIG. 2 shows a knitting structure chart relating to L1 and L3.

  The knitting yarn L1 (indicated by white yarn) is used to knitting a row of stitches extending in the warp direction adjacent to both sides of the warp insertion yarn L2 (indicated by hatched yarn), and the ground yarn L3 (black yarn). Is displayed in the stitch row while being swung in the weft direction. The knitting yarn L1 is formed into two chain stitches 1 and then swung into adjacent stitch rows and knitted by the closed loop 2 to form the chain stitch 1, and then returns to the original stitch row and again by the closed loop 2. Knitted. In this way, the knitting yarn L1 is knitted in the adjacent stitch row while being knitted alternately, so that the presser portion that contacts the warp insertion yarn when swung in the weft direction to go to the adjacent stitch row. 3 is formed. In FIG. 1, the pressing portion 3 comes into contact with the warp insertion thread from the front side of the sheet.

  On the other hand, the base yarn L3 is alternately knitted into the stitches of the two stitch rows sandwiching the two stitch rows, and is knitted while being swung in the weft direction, so that the warp insertion yarn is applied from the back side of the page. It comes to touch.

  Therefore, the warp insertion yarn L2 comes to be clamped from both sides by the pressing portion 3 and the ground yarn L3, and is held in the ground structure in a stable state. And since the space | interval of the holding | suppressing part 3 can be adjusted with the length which the knitting yarn L1 chain-knits by the stitch row | line | column, the area of the warp insertion yarn L2 exposed from between the holding | suppressing parts 3 can be adjusted easily. That is, when it is desired to expose a large amount of the warp insertion yarn L2, if the length of the chain knitting of the knitting yarn L1 is increased, the interval between the pressing portions 3 is increased, and the exposed area of the warp insertion yarn L2 can be increased. . In addition, when the warp insertion yarn L2 is firmly held, the length of the chain stitch of the knitting yarn L1 may be shortened to narrow the interval between the pressing portions 3. Therefore, it is possible to knit the optimum ground structure by appropriately adjusting the interval of the presser portions 3 depending on what kind of yarn is used for the warp insertion yarn L2, and it is possible to knit with three pieces of ground. .

  When the presser 3 is knitted with a jacquard pattern on the side of the knitted fabric that is in contact with the warp insertion yarn L2, the ground structure is knitted in a stable state. There is no need to use it for holding the warp insertion yarn, and it is possible to weave a pattern without receiving such restrictions. Further, when the warp insertion yarn L2 is exposed on the surface, an action is formed such that the pattern knitted on the surface is raised.

  As knitting yarn and ground yarn, recycled fibers represented by rayon, natural fibers represented by cotton, semi-synthetic fibers such as acetate, polyester-based synthetic fibers represented by polyethylene terephthalate, aliphatic polyamides represented by nylon A synthetic fiber or a mixed fiber thereof can be used, and may be either a long fiber yarn or a spun yarn, and is not particularly limited.

  As the warp insertion yarn, recycled fiber represented by rayon, natural fiber represented by cotton, semi-synthetic fiber such as acetate, polyester synthetic fiber represented by polyethylene terephthalate, aliphatic polyamide synthetic represented by nylon In addition to fibers such as fibers or mixed fibers thereof, filaments made of metals, synthetic resins, or composite materials thereof can be used. It is also possible to use yarns having various forms and functions such as long fiber yarns, spun yarns, and decorative yarns.

  FIG. 3 shows a knitting structure relating to another embodiment according to the present invention, and FIG. 4 shows a knitting structure chart relating to L1 and L3. In this example, the stitch row is knitted by alternately knitting a plurality of knitting yarns L1 in the same manner as in the example of FIG. It is knitted. As in the example of FIG. 1, the pressing portion 3 for the knitting yarn L1 is in contact with the warp insertion yarn L2 on the front side of the drawing. As in the example of FIG. 1, the base yarn L3 is alternately knitted into the stitches of the two stitch rows sandwiching the two stitch rows therebetween, and is knitted while being swung in the weft direction, so that the back side of the paper surface It comes to contact the warp insertion thread. In the example of FIG. 3, a plurality of knitting yarns are entangled by the open loop and the stitch row is knitted, so that a knitted fabric having stretchability can be obtained.

  FIG. 5 shows a knitting structure relating to a modification of the embodiment of FIG. 1, and FIG. 6 shows a knitting structure diagram of L1 and L3 thereof. In this modified example, when the stitch row is knitted with the knitting yarn L1, the knitting yarn is knitted with three chain stitches, and the interval between the presser portions 3 is set to be increased accordingly. Therefore, the exposed area of the warp insertion yarn L2 is increased, and for example, when a reflective material is used for the warp insertion yarn, the reflectance can be increased.

  FIG. 7 shows a knitting structure relating to a modification of the embodiment of FIG. 3, and FIG. 8 shows a knitting structure diagram of L1 and L3. In this modification, as in the case of FIG. 5, when the stitch row is knitted with knitting yarns, the number of chain stitches of each knitting yarn L1 is increased so that the interval between the pressing portions 3 is increased.

  In this way, by adjusting the length of the chain stitch of the knitting yarn constituting the stitch row, the interval between the pressing portions can be easily adjusted. Therefore, it is possible to adjust appropriately according to the use of the knitted fabric, the material and function of the warp insertion yarn to be used.

  FIG. 9 shows a knitting structure relating to another modification of the embodiment of FIG. 1, and FIG. 10 shows a knitting structure diagram of L1 and L3. In this modification, the knitting yarn L1 is knitted by being swung to the second stitch row beyond the adjacent stitch row. Therefore, the presser 3 is doubled against the warp insertion yarn L2. Get in touch. Therefore, the warp insertion yarn is held in a more stable state.

  FIG. 11 shows a knitting structure relating to another modification of the embodiment of FIG. 3, and FIG. 12 shows a knitting structure diagram of L1 and L3 thereof. In this modified example, the knitting yarn L1 is knitted while being swung to the second stitch row as in the case of FIG. 9, and the presser 3 is double-contacted with the warp insertion yarn, so that it is more stable. The warp insertion yarn is held in the state.

  As described above, the number of the pressing portions 3 that come into contact with the warp insertion yarn can be adjusted by the number of stitch rows swung in the weft direction of the knitting yarn, and can be appropriately adjusted according to the use of the knitted fabric, the material and function of the warp insertion yarn. That's fine.

  In the above example, the swing width of the ground yarn L3 is constant, but the swing width can also be changed. For example, FIG. 13 shows a modification of the organization chart of FIG. 2, and FIG. 13 (a) shows a case where the stitches are alternately knitted into two stitch rows sandwiching one stitch row. b) shows a case of alternately knitting into adjacent stitch rows. When the swing width of the ground yarn L3 is reduced, the knitted fabric is thinly finished.

  The knitted fabric of the embodiment of FIG. 1 was knitted using a jacquard raschel knitting machine using three pieces of ground. As the knitting yarn, 84 dtex long fiber yarn made of polyester fiber was used, and as the ground yarn, 84 dtex long fiber yarn made of polyester fiber was used. Further, a processed yarn of 336 dtex made of polyester fiber was used as the warp insertion yarn. Knitting was done with 18 gauge. Furthermore, a knitted fabric in which a pattern was formed by knitting a jacquard pattern was created. The produced knitted fabric was held in a stable state without the warp insertion yarn coming off, and the warp insertion yarn was exposed on the surface and could be formed so that the jacquard pattern was raised.
