Description

  The present invention relates to a warp knitted fabric that is warp knitted using a double raschel machine, and has a greater stretchability in the weft direction than in the warp direction.

  Conventionally, as a warp knitted fabric with a stretch knitted using a double raschel machine, for example, a cylindrical knitted fabric using an elastic yarn as a knitting yarn is known (see JP 2001-303415 A). . This tubular knitted fabric has elasticity in both the warp direction and the weft direction by the elastic action of the elastic yarn.

  In addition to this, a warp knitted fabric using crimped yarn as a knitting yarn is also known (see JP 2005-2485 A). Similar to the elastic yarn, this knitted fabric has elasticity due to the elasticity of the crimped yarn.

  However, although the above conventional warp knitted fabrics seem to have functionally appropriate stretch properties, the appearance of the knitted fabric is monotonous that the knitted structure brings on, and lacks in design fun. .

  Further, elastic yarns and crimped yarns for expressing stretch properties are relatively expensive, and knitted fabrics using these yarns are naturally expensive. Further, the yarn having elasticity and crimp is troublesome to handle, and there is a problem that adjustment at the time of knitting takes time.

  The present invention has been made in view of the above circumstances, has a sufficient stretch property even when a general yarn is used, and has an excellent design whose appearance greatly changes by stretching. The purpose is to provide a warp knitted fabric capable of imparting sex.

The present invention for achieving the above object is a warp knitted fabric for garments knitted using a double raschel knitting machine, and is a rib-shaped surface ridge that protrudes curved in the front side along the warp direction. And a rib-like back ridge that protrudes in a curved manner on the back side along the warp direction and has a shape in which a plurality of rows are alternately continued in the weft direction, and the shape of the cut surface along the weft direction is wavy According to the warp knitted fabric for clothes formed in

This warp knitted fabric uses a double raschel knitting machine having two rows of needle beds on the front (front) side and back (back) side, and the front side of the denbi knitting part (front side main knitting part) in the weft direction one organizing at predetermined intervals, as well behind the needle, Denbi knitted portion having a predetermined width (backside main knitting section) knitted in the weft direction at a predetermined interval, further, the backside main knitting of the phase to be parallel the Shifting in the weft direction with respect to that of the front main knitting portion, each back side main knitting portion is knitted so as to be positioned at an intermediate position between the front side main knitting portions, and the side edge and back side of the adjacent front side main knitting portion obtained by knitting tethered warp direction by the main knitting section double chain knitting or double Denbi knitting the side edges of the.

According to the inventor's empirical knowledge, when a knitted structure of denbi knitting is knitted using a double raschel knitting machine, the knitted fabric is curved outward in the warp direction and contracted in the weft direction. It becomes.

  Therefore, the warp knitted fabric obtained by the knitting method has a front main knitting portion that curves and protrudes to the front side along the warp direction, and forms a rib-shaped front ridge portion that shrinks in the weft direction. Similarly, the curved portion protrudes in the back side along the warp direction and forms a rib-like back ridge portion contracted in the weft direction, whereby the shape of the cut surface along the weft direction has a wave shape. It will be a thing.

  Thus, in such a warp knitted fabric, the front ridge and the back ridge are curved outward and protruded along the warp direction, and contracted in the weft direction. Compared to, it has a very high stretch in the weft direction. That is, when the knitted fabric is pulled in the weft direction, the front ridge portion and the back ridge portion are deformed flat in the weft direction so that the entire knitted fabric is stretched in the weft direction and the applied load is removed. The contraction force causes the contraction in the weft direction to restore the original state.

  In addition, as described above, the warp knitted fabric has the property that the front ridge and the back ridge are each contracted in the weft direction. The front ridges are in a state where the respective intervals are clogged, and similarly, the double row back ridges formed on the back side are also in a state where the respective intervals are clogged. Therefore, when the knitted fabric is observed from the front side, it is difficult to visually recognize the back ridge, and conversely, when the knitted fabric is observed from the back side, it is difficult to visually recognize the front ridge.

  When such a warp knitted fabric is pulled in the weft direction, as described above, the front and back ridges deform in a flat shape in the weft direction, and between the front and back ridges. The interval is increased and the entire knitted fabric is stretched in the weft direction. At this time, the back ridge can be visually recognized from the front side of the knitted fabric, and the front ridge can be visually recognized from the back side of the knitted fabric. .

  Therefore, for example, if the color of the yarn for knitting the front ridge and the color of the yarn for knitting the back ridge are different, when the warp knitted fabric is in a contracted state, the front ridge is formed from the front side. Only the color of the back ridge is visible, and from the back side only the color of the back ridge is visible, but by pulling the warp knitted fabric in the weft direction, the vertical stripe pattern of the back ridge is visible Similarly, the vertical stripe pattern of the front protrusion is visible from the back side.

  As described above, according to the warp knitted fabric according to the present invention, it is possible to impart an excellent design property that its external appearance is greatly changed by stretching it in the weft direction.

  The warp knitted fabric according to the present invention can be used as a component such as sportswear. However, when the knitted fabric is used as a sewn product, the warp knitted fabric conforms to the warp direction. Flat ears are preferably knitted on both sides.

  As described above, the warp knitted fabric according to the present invention has a three-dimensional shape having a front ridge portion and a back ridge portion. Therefore, if this is used for sewing as it is, there arises a disadvantage that good sewing cannot be performed due to deformation of the knitted fabric at the time of sewing, or a sewing wrinkle is generated.

  Therefore, by knitting the ears on the knitted fabric, sewing can be performed on the ears, and deformation of the knitted fabric and sewing wrinkles at the time of sewing can be prevented.

  In addition, it is preferable that the said ear | edge part is knitted by the same knitting structure as the said joint knitting part. If the same knitting structure is used, the guide bar of the double raschel knitting machine can be shared by the ear portion and the knitting portion, and the workability is improved.

  Moreover, the said knitting part and the ear | edge part are knitted using the needle | hook of a front side and a back side, respectively.

As described above, according to the warp knitted fabric according to the present invention, it has an extremely high stretch property in the weft direction compared to the warp direction, and when this is used for clothes, it has a feeling of fit and has mobility. Can be good clothes. In particular, knitting structure table ridges and back ridges are Den bi ed only, since the part is excellent in breathability, the use of this such as sportswear, which is preferable.

  Moreover, since the external appearance of the warp knitted fabric according to the present invention is greatly changed by stretching the warp knitted fabric in the weft direction, excellent design properties can be imparted. Furthermore, what knitted the ear part can be easily sewn.

It is drawing seen from the arrow B direction in FIG. It is drawing which extended the warp knitted fabric in FIG. 2 in the weft direction. It is drawing seen from the arrow D direction in FIG. It is explanatory drawing for demonstrating the usage example of the warp knitted fabric which concerns on this embodiment.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the garment warp knitted fabric 1 of this example has rib-shaped front ridges 2, 2. . . And rib-like back ridges 3, 3 which protrude in a curved direction along the warp direction. . . In the weft direction (C direction) alternately in a plurality of rows, the shape of the cut surface along the weft direction is wavy, and the ears on both sides of the knitted fabric along the warp direction 4 and 4 are provided.

  In FIGS. 1 and 2, the lower side is illustrated as the surface of the warp knitted fabric 1, and the upper side is illustrated as the back surface of the warp knitted fabric 1.

  The warp knitted fabric 1 can be knitted by using a known double raschel knitting machine having two rows of needle beds on the front (front) side and the back (back) side.

That is, a denvi knitting part (front side main knitting part) having a predetermined width with the front side needle of the double raschel knitting machine 5,5. . . Are knitted at predetermined intervals in the weft direction, while the back side needle is similarly knitted with a predetermined width (back side main knitting portion) 6,6. . . Are further knitted at predetermined intervals in the weft direction, and the phase of the back side main knitting portion 6 arranged in parallel is shifted in the weft direction with respect to that of the front side main knitting portion 5 so that each back side main knitting portion 6 with it organized so as to be positioned in an intermediate position between 5 and knitted connects side edges of the front-side main knitting section 5 and the side edges of the backside main knitting section 6 by the double chain knitting or double Denbi knitting through direction close ( Joiner 7), on both sides of the knitted fabric, joiner 7,7. . . Are obtained by knitting the ears 4 and 4 respectively.

  The connecting knitting part 7 and the ear part 4 are knitted using front and back needles, respectively.

In the warp knitted fabric 1 knitted in this way, as described above, the knitted fabric portion of the denbi knitting, that is, the front side main knitting portion 5 and the back side main knitting portion 6 are curved outward along the warp direction. Since the warp knitted fabric 1 has a property of contracting in the weft direction, the obtained warp knitted fabric 1 has a rib-shaped front surface in which the front side main knitting portion 5 protrudes by curving to the front side along the warp direction. The ridge portion 2 is formed, and the back side main knitting portion 6 is similarly curved and protrudes in the back side along the warp direction, and the rib-like back ridge portion 3 is contracted in the weft direction. As shown in FIG. 2, the shape of the cut surface along the weft direction has a wave shape.

  Thus, the warp knitted fabric 1 of this example has the property that the front ridge portion 2 and the back ridge portion 3 are curved and protrude outward along the warp direction, and contracted in the weft direction. Therefore, it has a very high stretch property in the weft direction compared to the weft direction.

  That is, when the warp knitted fabric 1 is pulled in the weft direction, as shown in FIG. 4, the front ridge portion 2 and the back ridge portion 3 are deformed flat in the weft direction, so that the entire knitted fabric in the weft direction. Stretched. When the applied load is removed, the contraction force causes the contraction in the weft direction to restore the original state.

  Moreover, since the warp knitted fabric 1 of this example is provided with the property that the front protrusion part 2 and the back protrusion part 3 each shrink | contract in a weft direction as mentioned above, it forms in the front side by each shrinkage | contraction action. The double row front ridge portions 2 are in a state where the respective intervals are clogged, and similarly, the double row back ridge portions 3 formed on the back side are also in a state where the respective intervals are clogged. Therefore, when the knitted fabric 1 is observed from the front side, it is difficult to visually recognize the back ridge portion 3, and conversely, when the knitted fabric is observed from the back side, it is difficult to visually recognize the front ridge portion 2. It has become.

  For example, as shown in FIG. 2, if a gray yarn is used for the front ridge portion 2, the connecting knitting portion 7 and the ear portion 4, and a white yarn is used only for the back ridge portion 3, this knitted fabric When 1 is viewed from the front side, it is recognized as gray as a whole as shown in FIG.

  When such a knitted fabric 1 is pulled in the weft direction, as shown in FIG. 4, the front ridge portion 2 and the back ridge portion 3 are deformed into a flat shape in the weft direction, so that And the back ridge portion 3 is opened, and the entire knitted fabric 1 is stretched in the weft direction. At this time, the back ridge portion 3 is visually recognized from the front side of the knitted fabric 1 as shown in FIG. Thus, a vertical stripe pattern of the white portion of the back ridge portion 3 and the gray portion of the front ridge portion 2 is formed.

  Thus, according to the warp knitted fabric 1 of the present example, by extending this in the weft direction, it is possible to impart an excellent design property that its appearance (shape, color, pattern) changes greatly.

  Further, as shown in FIG. 6, the warp knitted fabric 1 of this example can be used as a component of various clothes such as sportswear 10, but the ears 4 are knitted on both sides of the knitted fabric. Even if it has a three-dimensional shape such as the front ridge portion 2 and the back ridge portion 3, sewing on the ear portion 4 prevents deformation of the knitted fabric or sewing wrinkles at the time of sewing. be able to.

Further, constitute a knitting structure of Table ridges 2 and the back protrusions 3 from Denbi knitting, since this department is highly breathable, according warp knitted fabric 1 is suitably used in sportswear Can do .

  As mentioned above, although one Embodiment of this invention was described, the specific aspect which this invention can take is not limited to this at all.

  For example, in the above example, the ears 4 are provided on both sides of the knitted fabric, but it is not necessary to provide the ears 4 unless particularly required.

  Moreover, there is no restriction | limiting in the thread | yarn which can be used for the warp knitted fabric which concerns on this invention, A general thread | yarn or a special thread | yarn can be used freely.

  The warp knitted fabric according to the present invention has extremely high stretchability in the weft direction, and when this is used for clothes, the clothes can have good mobility while having a fit. Moreover, since the external appearance changes greatly by extending this in the weft direction, it is possible to impart excellent design properties, and it is possible to easily sew the one knitted with the ear part.
