2. Description of the Related Art For conventional light-reflecting products, light-reflecting yarns may be mixed in a fabric structure (for example, Japanese Patent Laid-Open No. 7-1).
There is a product in which a light-reflecting yarn is mixed in a plain base cloth such as a warp knitted 1 × 1 tricot (see, for example, Utility Model Registration No. 3023097).

[0003]

With respect to the conventional light-reflecting product, the light-reflecting yarn is subjected to an eve wrap on a plain base cloth such as a warp knitted 1 × 1 tricot to obtain a floating portion and a sinking portion. Although it is described (see Utility Model Registration No. 3023097). Reflection of the light-reflecting yarn is not completely effective because the floating portion is slightly raised, and the light reflectance is small because there are few floating portions.
Further, since the light-reflecting yarn is simply wrapped in 1 × 1 tricot, the light-reflecting yarn may easily come off, and may be caught during use and come out.

According to the present invention, the light-reflecting yarns are arranged in a straight line without floating or sinking, and the light-reflecting yarns are completely exposed on the surface from the holes of the mesh structure and the light-reflecting yarns are formed at the knots of the mesh. The purpose is to fix the thread and make it difficult to pull out.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples with reference to the drawings. As a machine for knitting the warp knitted fabric of the present invention, a Raschel machine manufactured by Karl Mayer was used. The number of guide bars (number of reeds) is 6, of which L ₁ ~
5 pieces of L ₅ are used, the knitting width is 130 inches, and the gauge is 18
It is a gauge. The mechanical rotation speed was 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 yarn arrangements 1 to 5 described later. 1 is a chain knitting yarn, and nylon 210d was used. Since the yarn insertion is a total stuffing and knitting is performed using L ₁ which is the foremost guide bar, this chain knitting yarn is fixed to the insertion yarn 2 which is a pressing yarn by the guide bar L ₂ described later. There is.

Reference numeral 2 denotes an insertion thread, which is thrown over three needles. The insertion thread 2 was made of nylon 210d to be fully packed. 3 is a light-reflecting thread, which is a flat thread with a width of 0.5 mm. A number of beads that become light-reflecting fine particles are attached and processed on the thread. The thread is nylon, polyester, vinyl chloride, acrylic. Etc. may be used. The guide bar of the light-reflecting yarn 3 is L ₃ , and in the embodiment, one yarn is removed and the knitting is performed in a straight line. However, if the density of the light-reflecting yarn 3 is desired, the yarn can be further removed.

Numerals 4 and 5 are mesh knitting yarns, and one knitting yarn is inserted and one knitting yarn is continuously knitted using nylon 420d. The mesh knitting yarns 4 and 5 are in mutually opposite underlap motions. It is thrown to and is organized.
The courses of the mesh knitting yarns 4 and 5 correspond to the light-reflecting yarn 3 in four courses, but when the ratio of the light-reflecting yarn 3 to be exposed on the surface is changed or the texture is changed, 6 courses and 8 courses are used. The number of courses can be changed corresponding to the courses.

The light-reflecting yarn 3 is sandwiched between the inserting yarn 2 and the sinker loop of the mesh knitting yarns 4 and 5, and is fixed.
The holes H of the mesh appear on the surface. In particular, when the mesh knitting yarns 4 and 5 and the inserting yarn 2 of the pressing yarn are formed in black, the reflection effect of the light reflecting yarn 3 becomes clearer. FIG. 2 is a view of the substantive diagram of the above-mentioned organization as seen from the front side of the knitting.

FIG. 3 is a substantial view seen from the back of the knitting. As can be seen from any of the figures, the light-reflecting 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 with each other to cause light reflection. The sex thread 3 is pressed down. The light-reflecting yarn 3 is preferably a flat yarn in terms of reflection efficiency, but is not limited to this.

The chain numbers of the above knitted structure 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 /
4−2 / L ₁ = 4−6 / 4−2 / 2−0 /
2-4 / FIG. 4 shows a knitting structure chart of another embodiment. The operations of the guide bars L _{1 to} L ₅ are sequentially performed by the yarn arrangement of yarns 6 to 10 described later. FIG. 5 shows a substantive diagram of the above organizational chart,
6 is a view seen from the front of the knit, and FIG. 6 is a substantial view seen from the back of the knit. 6 is a chain knit, 7 is an insertion yarn, 8 is a light-reflecting yarn, 9,
10 is a mesh knitting yarn.

In FIGS. 4 to 6, the light-reflecting threads 8 are alternately arranged in a zigzag manner from the holes H of the mesh and appear on the surface. The light-reflecting yarns 8 may be stuffed together as shown in the figure, or may be put in one and two may be drawn in a zigzag manner. The above-mentioned knitting structure is an example of the warp knitted fabric having the light reflectivity of the present invention, and is not limited to this.

[0018]

Since the present invention is configured as described above, it has the following effects. The light-reflective thread can be firmly fixed to the base cloth by inserting it between the thread knitted in a mesh shape and the pressing thread to make it difficult to slip out stably. The reflection efficiency can be effectively obtained by completely exposing the surface of the mesh from the hole.

Further, by selecting the condition of the surface of the light-reflecting yarns such that they are sequentially arranged in parallel or in a staggered manner, they can be used for various purposes. Further, since the light-reflecting yarn is linearly sandwiched between the pressing yarn and the mesh knitting yarn, even when the light-reflecting yarn is a flat yarn, it is not twisted and fixed.

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 appearance.
