Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is, for example, a light-reflective warp knitted fabric used in various clothing, industrial materials, sports equipment, life-saving equipment, such as sportswear, work clothes, general outerwear, women's outerwear, supporters, gloves, and sports shoes. It is about.
[0002]
[Prior art]
Sportswear, work clothes, etc. for the purpose of reflecting the illumination when illuminated by automobile headlights at night and contributing to traffic safety by facilitating early detection of pedestrians and road construction workers, etc. A light-reflective warp knitted fabric is attached to a general outer garment, a ladies' outer garment, etc., and an example of such a light-reflective warp knitted fabric is disclosed in JP-A-9-228205. Yes.
[0003]
As shown in FIG. 14, the light-reflective warp knitted fabric has an arbitrary portion of the warp knitted fabric a as a narrow warp knitted tape, for example, a flat reflective yarn c as a retroreflective film between wales b and b. It was configured as a light-reflective warp knitted tape intervened in a straight line and knitted (sandwiched) between the front and back insertion yarns d and e.
[0004]
[Problems to be solved by the invention]
However, the light-reflective narrow warp knitting tape having such a configuration has the following problems.
(1) Since the reflective yarn c is a retroreflective film that does not have stretchability and is linearly interposed between the front and back insertion yarns d and e, the warp knitted fabric a is elongated in the length direction. Therefore, the non-stretchable reflective yarn c arranged in a straight line prevents the stretchability of the entire light-reflective knitted fabric from being obtained.
Since the elasticity cannot be obtained in this way, even if the light reflective warp knitted fabric (tape) is used as a line tape for sportswear, it is difficult to follow the flexion of the knees and elbows. There was a difficult problem.
When the elastic yarn is used as the reflective yarn, the reflective yarn can be stretched as the narrow warp knitting tape is stretched. The yarn has a drawback that it is difficult to return to the original, and therefore, the reflective yarn could not be composed of a stretchable yarn.
[0005]
(2) Also, since the reflection thread c is simply interposed between the insertion threads d and e on the front and back, there is a problem that if a needle-like object is caught on the reflection thread c, it is easy to come off. It was.
[0006]
(3) Further, since the reflection yarn c is fixed only by being sandwiched between the insertion yarns d and e on the front and back sides, the insertion yarns are inevitably arranged at small intervals when viewed in the length direction of the reflection yarn. Therefore, there is a problem in that the portion of the insertion thread that covers the reflecting surface increases, resulting in poor reflection efficiency.
[0007]
An object of the present invention is to provide a light-reflective warp knitted fabric that can solve the problems (1) and (2), and can further solve the problem (3). The object is to provide a light-reflective warp knitted fabric.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the present invention employs the following means.
That is, the light-reflective warp knitted fabric according to the present invention is a light in which one or a plurality of flat reflective yarns having at least one surface as a reflective surface are knitted to the warp knitted fabric so as to extend in the length direction. It is a reflective warp knitted fabric, and the warp knitted fabric is formed as a double-sided knitted fabric that is knitted using a double raschel warp knitting machine and in which the knitted fabrics are connected by yarn portions. The flat reflective yarn is arranged on one side of the double-sided knitted fabric so that the reflective surface is exposed without twisting the yarn, and on the other side of the double-sided knitted fabric, a loop of 1 to 9 courses is interposed. Preferably, a loop of 1 to 4 courses is placed between them, and a desired loop selected in the length direction of the warp knitted fabric is knitted, and the knitted portion to the loop is on the one surface side. The braided portion is covered and hidden on the one surface side so as not to appear.
[0009]
In the light-reflective warp knitted fabric, it is preferable that an interval of 1 to 5 mm is provided between the knitted fabrics.
[0010]
When a plurality of the flat reflective yarns knitted so as to extend in the length direction of the warp knitted fabric are arranged in parallel, with respect to adjacent reflective yarns, the loop into which the reflective yarns are knitted, It is preferable to select by shifting the position in the length direction of the knitted fabric.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1-2, the light-reflective warp knitted fabric 1 according to the present invention is used as, for example, a line tape for sportswear, and a flat reflective yarn 3 having one surface as a reflective surface 2 is formed on the warp knitted fabric 5. It is knitted to extend in the length direction. 1-2 is explanatory drawing which shows the schematic structure, The insertion thread | yarn is abbreviate | omitted.
[0012]
In the present embodiment, the warp knitted fabric 5 is knitted using a double raschel warp knitting machine as shown in FIGS. The double knitted fabric 5 a is formed, and the chain knitting of the knitted fabrics 6 and 7 and the yarn portion 9 for connection are knitted with a single chain knitting yarn 10. As the chain knitting yarn, monofilaments or multifilaments of synthetic fibers such as polyester, and other various knitting yarns can be used. For convenience of explanation, the insertion thread is omitted in FIG.
[0013]
The reflective yarn 3 uses a flat yarn having a width of 0.5 to 3 mm, for example, a flat yarn having a width of 1 mm. When the width dimension of the reflecting yarn 3 is smaller than 0.5 mm, it is difficult to achieve a good light reflecting function, and when the width dimension is larger than 3 mm, it is reflected when the reflecting yarn 3 is knitted into the warp knitted fabric. The surface tends to be twisted, which is not preferable. As the reflective yarn 3, a material in which a large number of beads, which are light-reflective particles, are attached to a base tape can be used. The base tape is made of nylon, polyester, vinyl chloride, acrylic, or the like. Can be used.
[0014]
As shown in FIGS. 1 to 3, the reflective yarn 3 having such a configuration is disposed on one side 11 of the double-sided knitted fabric 5 a without exposing the reflective surface 2 to be twisted. The reflective surface portions 18 and 18 viewed in the vertical direction are in close contact with each other at the connecting portion 20. The reflective yarn 3 is knitted in the loop 13 selected on the other side 12 of the double-sided knitted fabric 5a with a loop of 1st to 9th course in between. In the present embodiment, as shown in FIGS. 2 to 3, the reflective yarn 3 is knitted with a loop 13 a of one course in between. In the organization chart of FIG. 3, for convenience of explanation, the reflective yarn 3 is shown in a tape shape at one end side, but the other portions are indicated by bold lines.
[0015]
FIG. 4 shows the overall structure of the organization, and the chain numbers of the knitting organization are as follows.
L ₁ : 0-0 / 0-2 / 0-0 / 0-0 /
L ₂ : 0-2 / 2-0 / 2/0 / 0-2 /
L ₃ : 0-0 / 0-0 / 4-4-4-4 /
L ₄ : 4-4 / 4-4 / 0-0 / 0-0 /
[0016]
Note that L ₁ is a guide bar for guiding the reflective yarn 3, and L ₂ is a guide bar for guiding the chain knitting yarn 10 that is looped to the front needle F and the back needle B and is knitted in the wale direction. L ₃ and L ₄ are guide bars for guiding the insertion yarns 15 and 16 to be inserted into the chain knitting yarn 10 while swinging left and right in the opposite direction by two wales.
[0017]
In the light-reflective warp knitted fabric 1 configured as described above, since the reflective yarn 3 is knitted and fixed to the loop 13 (FIG. 3) of the warp knitted fabric 5, it is interposed between the front and back insertion yarns. As in the conventional light-reflective warp knitted fabric in which the reflecting yarn is merely interposed linearly, the reflecting yarn 3 does not come off.
[0018]
The flat reflective yarn 3 exposes the reflective surface 2 on one side 11 of the double-sided knitted fabric 5a, and is knitted on the loop 13 on the other side 12 of the double-sided knitted fabric 5a. Therefore, even if the knitted portion 17 to the loop 13 becomes a protruding state due to twisting of the flat reflecting yarn 3, as shown in FIGS. 5 to 6, for example, the protruding portion is not formed on the double-sided knitted fabric 5a. Since it appears only on the other surface side 12 and does not appear on the one surface side 11, the linearity of the reflecting surface can be ensured.
[0019]
The reflecting yarn 3 is knitted into the loop 13 of the warp knitted fabric 5, and the reflecting surface portion 18 that appears on the one surface side 11 exhibits a curved state in a side view as shown in FIG. Unlike the case of the conventional light-reflective warp knitted fabric in which the yarn is merely interposed in a straight line, the reflective yarn can be expanded and contracted along with the expansion and contraction of the warp knitted fabric. Can be secured. For example, an elongation of about 10% can be secured.
[0020]
FIGS. 7-8 shows the other aspect of the light reflective warp knitted fabric 1 which concerns on this invention, so that it may extend to the warp knitted fabric 5 knitted as the single knitted fabric 5b in the length direction, A flat reflective yarn 3 having the same structure as described above, one side of which is a reflective surface 2, is knitted. FIG. 7 is a partial side view for explaining the schematic configuration of the light-reflective warp knitted fabric. In the organization chart of FIG. 8, the reflective yarn 3 is shown by a thick line for convenience of explanation.
[0021]
More specifically, the reflective yarn 3 is arranged in the knitting table 21 of the single knitted fabric 5b with the reflective surface 2 exposed without twisting the yarn, and viewed in the length direction of the single knitted fabric 5b. The reflecting surface portions 18 and 18 are in close contact with each other at the connecting portion 20. The reflective yarn 3 is knitted into a required loop 13 selected between loops of 1 to 9 courses on the knitted back 21 of the single knitted fabric 5b. In the present embodiment, the reflective yarn 3 is knitted with a loop 13a of one course in between. In FIG. 7, for convenience of explanation, the reflecting yarn 3 is shown in a tape shape on one end side.
[0022]
FIG. 8 shows the overall structure of the organization, and the chain numbers of the knitting organization are as follows.
L ₁ : 0-2 / 0-0 /
L ₂ : 0-2 / 2-0 /
L ₃ : 6-6 / 0-0 /
[0023]
L ₁ is a guide bar that guides the reflective yarn 3, L ₂ is a guide bar that guides a chain knitting yarn 19 that is looped to the needle and knitted in the wale direction, and L ₃ is The guide bar guides the insertion yarn 20 to be inserted into the chain stitch yarn 19 while swinging left and right by 3 wales.
[0024]
FIG. 9 shows another embodiment of the light-reflective warp knitted fabric 1 in which the flat reflective yarn 3 having the same structure as described above is knitted so as to extend in the direction of the length of the warp knitted fabric 5 as the double-sided knitted fabric 5a. For convenience of explanation, the reflecting yarn 3 is represented in a tape shape on one end side, and the other portion is represented by a thick line.
[0025]
10 to 12 are made by weaving a flat reflective yarn 3 having the same structure as described above, with one surface being a reflective surface 2 so as to extend in the length direction of the warp knitted fabric 5 knitted as a single knitted fabric 5b. 1 shows a light reflective warp knitted fabric 1. Also in these drawings, for convenience of explanation, the reflecting yarn 3 is shown in a tape shape on one end side, but the other part is shown by a thick line.
[0026]
[Other Embodiments]
The present invention is by no means limited to that shown in the above-described embodiment, and various design changes can be made within the scope of the claims. One example is as follows.
[0027]
(1) The light-reflective warp knitted fabric 1 according to the present invention is a variety of clothing items such as work clothes, general outerwear, women's outerwear, supporters, gloves, sports shoes, etc. And can be widely used for industrial materials, sports equipment, lifesaving tools, etc., and can be configured in a required form according to the application.
[0028]
(2) When a plurality of flat reflective yarns 3 knitted so as to extend in the length direction of the warp knitted fabric 5 are arranged in parallel as shown in FIG. By selecting the loop 13 into which the reflective yarn 3 is knitted so as to be displaced in the length direction of the warp knitted fabric 5, the reflection surface portions 18, 18 viewed in the length direction of the warp knitted fabric 5 are selected. For example, the connecting portion 20 may be shifted in a staggered manner, whereby the appearance of the reflecting surface 2 of the light-reflective warp knitted fabric can be improved. When the connecting portion 20 is continuous in the width direction of the warp knitted fabric 5 as shown in FIG. 1, this may stand out linearly and impair the appearance of the light reflective warp knitted fabric. Thus, there is an advantage that this can be prevented by shifting the position.
[0029]
(3) When the warp knitted fabric 5 is a double-sided knitted fabric 5a, the knitted fabric is knitted in close contact with each other, and the warp knitted fabric is used for, for example, sports shoes and ski wear. May be knitted with an interval of 1 to 5 mm between the knitted fabrics.
[0030]
(4) The double-sided knitted fabric 5a is manufactured by a known knitting means, and may be any as long as the knitted fabrics on the front and back sides including the needle loop are connected to each other by the yarn portion. In addition to knitting the knitted fabrics with a single chain knitting yarn, the knitted fabrics may be knitted by knitting the front and back knitted fabrics with separate chain knitting yarns and connecting them with separate connecting yarns.
[0031]
(5) When the loop into which the reflective yarn is knitted is set to the required loop selected between the 6th to 10th courses of the warp knitted fabric, the reflective surface portion that appears on one side of the warp knitted fabric Since the length of 18 is relatively long, it is preferable that the reflecting surface portion 18 is appropriately pressed with a pressing thread in order to stabilize the reflecting surface portion.
[0032]
(6) Both sides of the reflective yarn may be reflective surfaces, but at least one surface may be formed on the reflective surface.
[0033]
【The invention's effect】
The present invention has the following excellent effects.
(1) The light-reflective warp knitted fabric according to the present invention is knitted so that a flat reflective yarn extends in the length direction of the warp knitted fabric. When the warp knitted fabric is a double-sided knitted fabric, the flat reflective yarn is arranged on one side of the double-sided knitted fabric with its reflective surface exposed without twisting the yarn. When the warp knitted fabric is a single knitted fabric, the flat reflective yarn is arranged on the knitting surface of the warp knitted fabric with its reflective surface exposed without twisting the yarn.
Therefore, when the light-reflective warp knitted fabric according to the present invention is used, the reflective surface can be expressed linearly on the surface of the warp knitted fabric, for example, when illuminated by a headlight of an automobile at night. Reflected and can contribute to traffic safety by facilitating early detection of pedestrians and road construction workers. In addition, a unique fashion can be obtained by reflecting the illumination. [0034]
(2) Since the flat reflective yarn has a configuration knitted in a required loop selected in the length direction of the warp knitted fabric, the reflective yarn is interposed linearly between the front and back insertion yarns. Unlike the case of the conventional light-reflective warp knitted fabric that is not too much, it can be expanded and contracted according to the expansion and contraction of the warp knitted fabric.
Therefore, when this light-reflective warp knitted fabric is used as a line tape for sportswear, it can follow the flexion of the knees and elbows. Therefore, the conventional light-reflective warp knitted fabric is not used as a line tape. It does not cause a sense of incongruity as if it were.
[0035]
(3) Since the reflecting yarn is knitted into the required loop of the warp knitted fabric and fixed to the warp knitted fabric, the conventional light in which the reflecting yarn is simply interposed between the front and back insertion yarns. As in the case of a reflective warp knitted fabric, there is no problem that the reflective yarn comes off when a needle-like object is caught on the reflective yarn.
[0036]
(4) Since the conventional light-reflective warp knitted fabric has only the reflective yarn interposed between the front and back insertion yarns in a straight line, it is indispensable to fix the reflective yarn to the warp knitted fabric. In addition, when viewed in the length direction of the reflecting yarn, there is a problem that the inserting yarn has to be arranged at a small interval, and therefore, there is a problem that the portion of the inserting yarn covering the reflecting surface increases and the reflection efficiency is deteriorated.
On the other hand, the light-reflective warp knitted fabric according to the present invention fixes the reflective yarn by knitting the reflective yarn into the loop of the warp knitted fabric instead of interposing the reflective yarn between the insertion yarns as in the prior art. Since it is a structure, the light reflective warp knitted fabric with high reflection efficiency compared with the past can be obtained. When the length of the reflective surface portion appearing on the surface of the warp knitted fabric is long (for example, a loop of about 6-9 courses is interposed between loops to be knitted) and the reflective surface portion may become unstable In some cases, the reflective yarn may be appropriately pressed with a presser yarn, but it is not necessary to press the reflective yarn at small intervals as in the conventional light-reflective warp knitted fabric pressed with an insertion yarn. Don't be.
[0037]
(5) When the light-reflective warp knitted fabric according to the present invention is applied as a double-sided knitted fabric, the reflective yarn disposed with the reflective surface exposed on one side of the double-sided knitted fabric is the double-sided knitted fabric. Since it is knitted into a required loop on the other surface side, even if the knitted portion into the loop becomes a protruding state due to twisting of a flat reflecting yarn, for example, this protruding state is obtained. Since the portion does not appear on the one surface side of the double-sided knitted fabric, the linearity of the reflective surface can be secured, and a light-reflective warp knitted fabric excellent in appearance can be manufactured.
[0038]
(6) When the reflective yarns are arranged in parallel, with respect to the adjacent reflective yarns, the loop of the warp knitted fabric into which the reflective yarns are knitted is selected by being displaced in the length direction of the warp knitted fabric. By configuring so as not to line up in the width direction of the knitted fabric, the connecting portions 20 of the portions appearing on the surface of the warp knitted fabric can be formed in a staggered arrangement as shown in FIG. 13, for example. Thereby, compared with the case where the connection part 20 is located in a line, the appearance of a reflective surface can be improved.
