DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a knitting outline diagram of a two-row needle bed warp knitting machine for knitting a double-side warp knitted fabric.
When knitting a double-side warp knitted fabric WK on a two-row needle warp knitting machine, the front knitting yarn group FY is controlled by the front guide group FG, the front knitted fabric FK is knitted by the front needle FN, and the back knitting yarn group BY is backed. Control with the guide group BG, knitting the back knitted fabric BK with the back needle BN, and connect it with a knitting yarn SY for binding, or knitting for the front knitted fabric and the back knitted fabric A single knitted fabric was formed using the yarn systematically for binding.
[0016]
When adopting another series of binding knitting yarns, as shown in FIG. 1, the binding knitting yarn SY is controlled by the binding guide SG and is passed over the front needle FN and the back needle BN. The knitted fabric FK and the back knitted fabric BK are connected.
Further, when the knitting yarns for the front knitted fabric and the back knitted fabric are used in combination for systematic binding, for example, any series of the front knitting yarn group FY is systematically spread over the back needle BN and knitted. Conclude.
In both cases, the presence of the knitting yarn for binding affects the performance of the knitted fabric, and the knitted yarn of the front and back knitted fabrics appears on the surface of each knitted fabric, so that the front and back are completely knitted. This causes problems such as difficulty.
[0017]
Therefore, in the present invention, the conventional double-sided means is employed that does not use the knitting yarn SY for binding, and does not systematically use the knitting yarn for the front and back knitted fabrics for binding. Solved various problems of warp knitted fabric.
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Here, the organization chart and the chain link table used for the description of the present embodiment are described on the assumption that the front and back knitted fabrics are knitted by a single-row needle bed warp knitting machine. In actual knitting, these organization charts and chain link tables may be converted for a two-row needle bed warp knitting machine.
This is because it is difficult to associate the actual knitted fabric form when the organization chart is described for a two-row needle bed warp knitting machine. It does not interfere with the summary.
[0018]
(First embodiment)
In the first embodiment, as shown in FIG. 2 (A), the front and back knitted fabrics are the plain knitted fabrics 1 having a double Denby structure.
The double-Denby structure is composed of two series of structures, a Denby structure 11 (1-0 / 1-2) and a Denby structure 12 (1-2 / 1-0).
[0019]
When a double-Denby structure is knitted with the front needle and back needle of a two-row needle bed warp knitting machine, as shown in FIG. 1, the front needle FN is front knitted with two front guides FG1 and FG2. The yarns FY1 and FY2 are fed, and the back needle BN is knitted by feeding the back knitting yarns BY1 and BY2 with the two back guides BG1 and G2. In such a case, as a matter of course, the front knitted fabric The two knitted fabrics of FK and back knitted fabric BK are separated and knitted.
[0020]
When the knitted fabric is connected to form a single knitted fabric, it is necessary to separately provide a binding guide SG and connect the front knitted fabric FK and the back knitted fabric BK with the binding yarn SY.
However, the existence of the binding yarn SY has already been described as causing the serious problem that the binding yarn SY is exposed on the surface of the front and back knitted fabrics in addition to simply increasing the weight and thickness of the knitted fabric. Street.
[0021]
Therefore, in this embodiment, as shown in FIG. 3, when viewed from the front of the knitting machine, each guide is arranged as a front guide FG1, a back guide BG2, a front guide FG2, and a back guide BG1, that is, the front guide FG2. The back knitting yarn FY1, the back knitting yarn BY2, the front knitting yarn FY2, and the back knitting yarn BG1 are sequentially introduced from the front of the knitting machine.
At this time, the back knitting yarn BY2 guided from the back guide BG2 to the back needle BN and the front knitting yarn FY2 guided from the front guide FG2 to the front needle FN are X-shaped between the guide and the needle as viewed from the side of the knitting machine. Will be crossed into a shape.
[0022]
Each guide is controlled according to the double-Denby structure for knitting. Here, the movement directions of the knitting yarns on the front and back knitted fabrics are opposite to each other.
The front guide FG1 is controlled according to Denby tissue 11 (1-0 / 1-2) and the front guide FG2 is controlled according to Denby tissue 12 (1-2 / 1-0), whereas the back guide BG1 is controlled according to Denby tissue 12 (1 -2 / 1-0), the back guide BG2 is controlled according to Denby tissue 11 (1-0 / 1-2).
That is, the front and back knitted fabrics are double-Denby structures, but the movement directions of the knitting yarns are opposite.
[0023]
When knitting with the above settings, as shown in FIG. 4 (A), the front guide FG2 and the back guide BG2 underlap each other in the opposite directions, and over the front needle FN and the back needle BN, respectively. Since the wrapping is performed, the sinker loop FS formed by the front knitting yarn FY2 and the sinker loop BS formed by the back knitting yarn BY2 are intertwined so as to be entangled with each other (FIG. 4B when not crossing in an X shape) Sinker loops FS and BS are not entangled as shown in FIG. 2), and the two knitted fabrics FK and BK on the front and back sides are securely connected by the entanglement of the sinker loops FS and BS as shown in FIG. In addition, a double-sided warp knitted fabric is obtained in which the knitting yarns are not exposed to the surface of the knitted fabric.
Further, the two knitted fabrics FK and BK can be displaced from each other within the range of the length of the sinker loop, and there is an advantage that flexibility in use can be obtained.
[0024]
Also, if you use red yarn for the front knitting yarn group FY and black yarn for the back knitting yarn group BY, the double-sided warp knitted fabric WK is clearly knitted in red and black. can get.
Furthermore, if the material is properly used, such as using polyester yarn for the front knitting yarn group FY and nylon yarn for the back knitting yarn group BY, a double-sided warp knitted fabric WK with different front and back materials can be obtained.
When the same color and different materials are used for the front and back knitted fabrics, the front and back can be color-coded by post-dyeing.
[0025]
(Second Embodiment)
In the present embodiment, an example will be given in which two knitted fabrics on the front and back sides are partially joined.
The front and back knitted fabric is assumed to be a plain knitted fabric 1 having a double Denby structure similar to that of the first embodiment.
The front knitted fabric is composed of a denby structure 11 and a denby structure 12, and among them, as shown in FIG. 5A, four front knitting yarns FY2 for knitting the denby structure 12 on the side in contact with the back knitted fabric BK are provided. The separated series yarns FY21 and FY22 (thick line portions in FIG. 5) are separated into two at a ratio of 1: 1, and the yarns are respectively guided to the front guides FG21 and FG22 for control knitting.
[0026]
Specifically, it is repeated that four knitting yarns are introduced into the front guide FG21 and then one knitting yarn is introduced into the front guide FG22.
Then, as shown in FIG. 6, the front guide FG22 and the back guide BG2 are replaced and arranged in the order of the front guides FG1, FG21, back guide BG2, front guide FG22, and back guide BG1 when viewed from the front of the knitting machine. Set.
Both the front guide FG21 and the front guide FG22 are similarly controlled according to the Denby structure 12 (1-2 / 1-0).
[0027]
If the double-Denby structure is knitted with such a setting, the front knitting yarn FY22 from the front guide FG22 to the front needle FN and the back knitting yarn BY2 from the back guide BG2 to the back needle BN are interlaced in an X shape. Thus, the sinker loop FS formed of the front knitting yarn FY22 and the sinker loop BS formed of the back knitting yarn BY2 are interlaced and entangled with each other, and the two knitted fabrics on the front and back sides are spaced apart, and the partial tying is performed. Made.
[0028]
As shown in FIG. 5B, the double-side warp knitted fabric that has been partially connected in this way has a connecting portion K in the vertical direction with a constant interval, and has two knitted fabrics on the front and back sides. Is separated into two at the part without the connecting part, and furthermore, the degree of freedom of displacement is obtained, and a knitted fabric that is more flexible with respect to bending can be obtained, and the heat insulation effect function can be achieved by forming an air layer. Will have.
[0029]
(Third embodiment)
In the present embodiment, a plain knitted fabric 1 having a double-Denby structure is adopted for the back knitted fabric BK, as in the first and second embodiments, and the front knitted fabric FK has holes as shown in FIG. A net knitted fabric 2 having eyes 23 is employed.
The net knitted fabric 2 is formed of a two-line structure, and the front guide FG1 is a structure 21 (1-0 / 1-2 / 1-0 / 1-2 / 2-3 / 3-3 / 3/3 / 3-3- 4 / 3-2-2-1), the front guide FG2 is moved to the structure 22 (3-4 / 3-2 / 3-4 / 3-2-2 / 2-1 / 1-0 / 1-2 / It is controlled according to the chain link 1-0 / 1-2 / 2-3).
The front knitting yarns FY1 and FY2 are respectively guided in a state of 3 in 1 out to the front guides FG1 and FG2 (repeating that 3 knitting yarns are guided to the guide and that one yarn is released). By knitting, the net knitted fabric 2 having the hole 23 is formed.
[0030]
As shown in FIG. 3, the guides are arranged from the front of the knitting machine to a front guide FG1, a back guide BG2, a front guide FG2, and a back guide BG1.
The flow of the knitting yarn at this time is such that the back knitting yarn BY2 guided from the back guide BG2 to the back needle BN and the front knitting yarn FY2 guided from the front guide FG2 to the front needle FN are viewed from the side of the knitting machine. Crossed in a letter shape.
Here, as in the first embodiment, the back guide BG2 is controlled according to the chain link of (1-0 / 1-2) so that the moving directions of the front knitting yarn FY2 and the back knitting yarn BY2 are opposite to each other. .
[0031]
If knitting is performed in such a setting, the back knitted fabric BK and the front knitted fabric FK having a double denby structure are securely connected by the intertwining of the sinker loops inscribed in the same principle as in the first embodiment. The
When the plain knitted fabric 1 and the net knitted fabric 2 are connected as described above, the hole 23 of the front knitted fabric FK is sewn to the back knitted fabric BK, and the hole 23 is not opened, as shown in FIG. Thus, a slit-like hole 24 is formed.
Usually, a net knitted fabric. Such a knitted fabric looks like a plain texture, but actually, the slit-like holes reach the knitted fabric on the opposite side, and there is an effect of obtaining air permeability and water permeability.
[0032]
(Fourth embodiment)
In the present embodiment, the net organization 2 shown in FIG. 7 is used for both the front and back sides, similar to the second embodiment.
The front guide FG1 is the structure 21, the front guide FG2 is the structure 22, the back guide BG1 is the structure 22, and the back guide BG2 is the structure 21 so that the moving directions of the knitting yarns on the front and back knitted fabrics are opposite to each other.
Then, by arranging the front guide FG2 and the back guide BG2 so as to be replaced, the sinker loops are also entangled and connected.
Here, the two knitted fabrics of the front and back surfaces of this example are net knitted fabrics of the same structure, and the positions of the holes 23 are formed at the same positions, so that the holes 23 penetrate and are widely opened. It is done.
[0033]
(Fifth embodiment)
In the fifth embodiment, a knitted fabric is obtained in a state in which the positions of the holes of the two knitted fabrics on the front and back sides are shifted under the same conditions as in the fourth embodiment.
In the chain link table, the positions of the holes do not match by starting the knitting by shifting one of the two knitted fabric structures on the front and back sides.
If the positions of the holes do not match, the holes in the back knitted fabric will be sewn together with the holes in the back knitted fabric, and the holes in the back knitted fabric will be sewn together. The holes are not opened, and slits 24 are formed on the front and back sides as shown in FIG.
At first glance, such a knitted fabric appears to be a plain texture, but actually, the slit-like holes 24 reach the knitted fabrics on the opposite sides, and there is an effect that air permeability and water permeability can be obtained.
[0034]
As described above, in the first to fifth embodiments, the front and back knitted fabrics FK and BK are a plain knitted fabric and a plain knitted fabric, a partially connected knitted fabric, a plain knitted fabric and a net knitted fabric, and a net knitted fabric. And net knitted fabrics, those with perforated holes in them and those that have not penetrated were explained in detail, but the second implementation also in plain knitted fabrics and net knitted fabrics, net knitted fabrics and net knitted fabrics Needless to say, it is possible to adopt a means of partial connection similar to the above-described form.
[0035]
That is, in the net knitted fabric 2 on either the front or back side, for example, as shown in FIG. 8, two front knitting yarns FY2 for knitting the structure 22 for knitting the front knitted fabric FK are provided in a ratio of 2 to 1. As shown in FIG. 6, the separated series yarns FY21 and FY22 (thick line portions) are introduced into the front guides FG21 and FG22, respectively, and the front guide FG22 and the back guide BG2 are replaced and arranged. If the control knitting is performed, the knitted fabrics on the front and back sides are partially joined together based on the same principle as in the second embodiment.
[0036]
Thus, in the case where partial connection is performed using the net knitted fabric 2, even if the hole 23 of the net knitted fabric does not penetrate, the hole 23 does not fit into the slit-shaped hole. Thus, a double-sided warp knitted fabric WK having an open hole 23 is obtained.
This is because, since the connection is partially performed, the front and back knitted fabrics FK and BK are separated in the vicinity of the hole 23, and the effect of sewing the hole does not occur.
In such a knitted fabric, there is a glimpse of the knitted fabric on the opposite side from the hole 23, and the effect of improving the design effect is obtained.
In addition, as for the colors of the front and back knitting yarns and the proper use of the material, the same as described in the first embodiment can naturally be performed in the second to fifth embodiments.
[0037]
Although the details of the present invention have been described above, the double-sided warp knitted fabric is not limited to these embodiments, and it goes without saying that other modifications and combinations are possible without departing from the essence thereof. .
For example, with respect to the structure used for the front and back knitted fabrics, the plain knitted fabric is not limited to the double denby structure, but may be a knitted fabric using chain stitches or insertion yarns, and the net knitted fabric is 3 in 2 out, or It is possible to change the size of the holes, the interval, etc. freely by changing the structure as 11 in 1 out.
[0038]
Further, the number of guides is not limited.
Furthermore, it is also possible to provide a laterally connected portion with a constant interval by a method of controlling and knitting the guide using chain stitches at the same position of the front and back knitted fabrics.
[0039]
【The invention's effect】

The binding yarn becomes unnecessary, and it is economical in terms of preparation and material amount, and it is flexible and thin, and the knitting yarn of the binding yarn and the front and back knitted fabrics are exposed on the surface of each knitted fabric. Therefore, clear knitting can be performed regarding the material, color, structure, etc. of the front and back knitted fabrics.
[0040]
In the double-sided warp knitted fabric of the present invention, the plain knitted fabric and the plain knitted fabric, the plain knitted fabric and the net knitted fabric, the net knitted fabric and the net knitted fabric, in which the perforations penetrate, or do not penetrate As mentioned, the front and back knitted fabrics can be combined freely, and the front and back knitted fabrics can be selected for full or partial connection. be able to.
[0041]
In the double-sided warp knitted fabric of the present invention, when the partial connection is made, the front and back 2
Sheet knitted fabric can be separated into two pieces at the part where there is no connection point, and a degree of freedom of displacement is obtained, and a knitted fabric that is more flexible with respect to bending is obtained, and heat insulation is achieved by forming an air layer. It is possible to have an effect function.
Also, in the case of a combination of a plain knitted fabric and a net fabric, a design effect is obtained such that the perforations of the net fabric are opened and a knitted fabric on the opposite side from the perforations can be seen.
[0042]
In the double-sided warp knitted fabric of the present invention, when the front knitted fabric FK and the back knitted fabric BK are net fabrics having holes, a large ventilation function is obtained when the holes are penetrated. In addition, when the holes are not penetrated, slit-like holes are formed so that the holes are not conspicuous and air permeability is obtained.
