[0003]

With respect to a conventional light-reflective product, a light-reflective yarn is evasion-wrapped on a plain base cloth such as a warp knitted 1 × 1 tricot to obtain a floating portion and a sinking portion. (See Utility Model Registration No. 3023097). The reflection of the light-reflective yarn is not completely effective because the floating part is slightly raised, and the light reflectance is small because the floating part is small.
In addition, since the light-reflective yarn is simply evasion-wrapped on a 1 × 1 tricot, the light-reflective yarn is easy to come off, and may be caught during use and come off.

According to the present invention, the light-reflective yarn is arranged in a straight line without floating or sinking, and the light-reflective yarn is completely exposed on the surface from the hole portion of the mesh structure, and the light-reflective yarn is formed at the knot of the mesh. The purpose is to stop the thread and make it difficult to pull it out.

[0005]

In order to achieve the above object, a light reflective warp knitted fabric according to the present invention is a warp knitted fabric mixed with a light reflective yarn as described in claim 1. A light-reflective yarn is inserted between a yarn knitted in a mesh shape by a plurality of guide bars and a presser yarn, and the light-reflective yarn is exposed on the surface in a hole portion of the mesh. As a result, the light-reflective yarn is held stably and hardly comes off. Since the light-reflective yarn appears on the surface from the hole of the mesh, a good reflection effect can be obtained.

In particular, when the light-reflective yarn is a flat yarn as described in claim 2, the reflection efficiency is high, and in the inserted state, the light-reflective yarn can be stably fixed to the base fabric without twisting. For knitting the light-reflective warp knitted fabric, a warp knitting machine having 4 to 6 guide bars, and a machine having a row of needle bars is desirable. The mesh-shaped knitting yarn and the presser yarn are characterized in that the mesh knitting yarn and the presser yarn are synthetic fiber yarns as described in claim 3, but natural fiber yarns may be used. A minimum of 4 courses or more of longitudinal repeat is preferred.

[0007] Further, regarding the mesh knitting yarn, claim 4
The mesh knitting yarns are knitted by two guide bars as shown in the figure, and are knitted one by one, one by one, and thrown in mutually opposite directions of the underlap motion. It is characterized by: That is, the mesh knitting yarn is knitted by at least two guide bars, and each of the guide bars is underwrapped in the opposite direction and a sinker loop is thrown out, thereby forming a knot portion of the mesh.

The yarns knitting the mesh may be overlapped every course to form a loop, or may be supplied as insertion yarns and held down by chain knitting yarns. Next, with respect to the holding yarn, the holding yarn is formed of an insertion yarn as described in claim 5, and the yarn for stopping the insertion yarn is a chain knitting. It is a thread suitable for sandwiching a light reflective thread.

The light-reflective yarns composed of flat yarns are fixed linearly between the sinker loop portion of the mesh knitting yarn and the presser yarn. Further, the arrangement and position of the light-reflective yarns are characterized in that the light-reflective yarns are continuously arranged as shown in claim 6 and appear on the surface at positions parallel to each other in the holes of the mesh. And a case in which the light-reflective yarns appear on the surface at the holes of the meshes arranged alternately in a staggered manner. The sex yarns appear side by side in parallel, and in the latter case, they appear at alternating staggered positions, and may be made to correspond to the intended use. In particular, the mesh knitting yarn and the presser yarn as in claim 7 Is characterized in that it is black, so that the presence of the light-reflective yarn can be enhanced and the reflection effect can be enhanced.

It is a gauge. The machine rotation was performed at 400 rpm.

FIG. 1 is a diagram showing the structure of the embodiment. The operation of the guide bars L _{1 to} L ₅ is clearly shown by the arrangement of yarns 1 to 5 described later. 1 is a chain knitting yarn, and nylon 210d was used. Yarn-in is the total packed, most since before the guide is bar in which with L ₁ to organize, the insertion yarns 2 This chain knitting yarn is pressing yarn by the guide bar L ₂ which will be described later with a stopping I have.

Reference numeral 2 denotes an insertion thread which is thrown over three needles. The insertion yarn 2 was fully packed using nylon 210d. Numeral 3 is a light-reflective yarn, which is a flat yarn having a width of 0.5 mm, and is formed by attaching a number of beads as light-reflective fine particles to the yarn. The yarn is made of nylon, polyester, vinyl chloride, acrylic, etc. Etc. may be used. Guide bars of the light-reflecting yarn 3 is L _3, but organized in a straight line with one vent in the embodiment, the request of the density of the light reflective yarn 3 may be further a thread trimming.

Reference numerals 4 and 5 denote mesh knitting yarns, each of which is made of nylon 420d and is continuously knitted without one yarn. It is thrown and organized.
The courses of the mesh knitting yarns 4 and 5 correspond to the light reflecting yarns 3 in four courses. However, when changing the ratio of the light reflecting yarns 3 exposed to the surface or changing the texture, six courses and 8 courses are used. The number of courses can be changed corresponding to the courses.

The light reflective yarn 3 is interposed between the insertion yarn 2 and the sinker loops of the mesh knitting yarns 4 and 5, and is stopped.
It appears on the surface at the hole H of the mesh. In particular, when the mesh knitting yarns 4 and 5 and the insertion yarn 2 of the presser yarn are formed in black, the reflection effect of the light reflective yarn 3 becomes clearer. FIG. 2 is a view of the entity diagram of the tissue as viewed from the front of the knitting.

FIG. 3 is an actual view as viewed from the back of the knitting. As can be seen from any of the figures, the light-reflective yarn 3 is completely exposed on the surface at the holes of the mesh, and at the knots of the mesh knitting yarns 4 and 5, the sinker loops intersect each other and light is reflected. The sex thread 3 is held down. The light reflective yarn 3 is preferably a flat yarn in terms of reflection efficiency, but is not limited to this.

The chain numbers of the knitted organization are as follows. Knitting _{L 1 = 2 - 0/0} - 2 / L 2 = 0 - 0/6 - 6 / L 3 = 0 - 0/0 - 0 / L 4 = 2 - 0/2 - 4/4 - 6 /

In FIGS. 4 to 6, the light reflecting yarns 8 are alternately arranged in a staggered manner from the holes H of the mesh and appear on the surface. The light-reflective thread 8 may be fully packed as shown in the figure, or may be staggered even if one thread is inserted and two threads are omitted. The knitted structure is only an example of the light-reflective warp knitted fabric of the present invention, and is not limited thereto.

[0018]

Since the present invention is configured as described above, it has the following effects. The light-reflecting yarn can be firmly fixed to the base cloth by inserting the light-reflecting yarn between the yarn knitted in a mesh shape and the presser yarn to make it difficult to pull out stably. Is completely exposed on the surface from the holes of the mesh, and the reflection efficiency can be effectively obtained.

Further, by selecting the state of the light-reflecting yarn that emerges on the surface, such as arranging the surface on the surface of the light-reflective yarn in parallel or sequentially in a staggered manner, the fiber can be used for various purposes. Further, since the light reflective yarn is linearly sandwiched between the presser yarn and the mesh knitting yarn, even if the light reflective yarn is a flat yarn, the light reflective yarn is not twisted and is stopped.

Further, by changing the size of the mesh and the color of the thread, it is possible to easily change the light reflectance and the texture in appearance.
