Description

The present invention relates to a ladder-shaped reflective band for clothes comprising a reflective tape and a base material for fixing the reflective tape.

At night, a reflection band is used to inform the driver of the car of the position of a pedestrian or bicycle driver. For the reflection band, a retroreflecting material that reflects light toward the light source is used.

As the retroreflective material, a material in which a plurality of minute glass beads are fixed to a base material or a prism in which minute irregularities are formed on a reflecting surface is used. Since glass beads and prisms are weak against friction, the surface of the retroreflective material is protected by a transparent resin layer (reference numeral 3) as in Patent Document 1. However, the color of the resin layer may turn yellow due to aging, the resin layer may peel off from the base material, or the visibility may deteriorate due to scratches.

Patent Document 2 discloses a decorative band for clothes formed by fitting a band-shaped reflecting material into a concave groove of a band-shaped cloth base material. The band-shaped reflector is fitted into the groove and then adhered to the groove, and the thread (reference numeral 13) is passed over the left and right convex portions. This garment decorative band has many steps for fixing the base material and the reflective material, and is complicated. Further, the area where the reflective material is exposed is large, and the reflective material is easily worn. Furthermore, there was a risk that the yarn would break due to friction.

The present invention provides a reflective band for clothes that has good visibility at night, is unlikely to wear a retroreflecting material due to friction, and is difficult to peel off a reflective tape, and can be easily manufactured.

A reflective tape composed of a strip-like retroreflective material and a base material for fixing the reflective tape. The base material is a pair of left and right vertical reinforcing portions corresponding to a vertical tree of a ladder, and the pair of left and right vertical reinforcing portions. And a plurality of transverse reinforcing portions corresponding to ladder rungs, wherein the longitudinal reinforcing portions are woven fabrics woven by warps and wefts, and the transverse reinforcing portions are formed of the warps and the wefts. The above-described problem is solved by a ladder-patterned reflective band for clothes, which is composed of any one of a plurality of woven yarns, and the reflective tape is fixed to a base material by the lateral reinforcing portion.

The reflective band for clothes of the present invention fixes the reflective tape and the vertical reinforcing portion of the base material by a lateral reinforcing portion that is wider than a single thread. The transverse reinforcing portion is formed by a plurality of warps or a plurality of wefts, and uses one of the warp and the weft constituting the longitudinal reinforcing portion as the plurality of yarns constituting the transverse reinforcing portion. It is. Since the lateral reinforcing portion is composed of a plurality of woven yarns, the reflective tape can be securely fixed with higher resistance to friction than when the reflective tape is fixed with a single yarn. Moreover, since the lateral reinforcing portion covers the reflective tape in a wide range, the reflective tape is not easily worn out.

As described above, the reflective tape is fixed by using either the warp yarn or the weft yarn constituting the pair of left and right vertical reinforcing portions as the lateral reinforcing portion. For example, the left and right vertical reinforcing parts are woven using warp and the central part interposed between the left and right vertical reinforcing parts is composed of only wefts with the warp omitted. The reflective tape is fixed by the weft. In this case, a plurality of warps constituting the left longitudinal reinforcing portion, a reflective tape, and a plurality of warps constituting the right longitudinal reinforcing portion are arranged in the order described from left to right, and there is one continuous weft. The reflective tape can be easily woven into the substrate. When passing the weft, the reflective tape can be fixed to the base material by allowing a group of a plurality of wefts to alternately pass through the front or back surface of the reflective tape. That is, as shown in FIG. 2 to be described later, a plurality of woven yarns of either one of the warp and the weft constituting the transverse reinforcing portion are a group of woven yarns, and a group of woven yarns is a reflective tape. It alternately passes through the front or back surface of this.

As described above, the reflective tape is woven into the substrate. Therefore, the surface of the reflective surface of the reflective tape is disposed at a position lower in the thickness direction than the surface of the substrate. Therefore, the reflective surface of the reflective tape is not easily exposed to friction and is not easily worn out.

As described above, any one of the warp and weft yarns constituting the transverse reinforcing portion is composed of a plurality of woven yarns and a group of woven yarns alternately passing through the front surface or the back surface of the reflective tape. The reflective surface of the reflective tape and the lateral reinforcing portion appear alternately and continuously in the longitudinal direction of the clothing reflective band. Since the reflecting surface and the lateral reinforcing portion are alternately arranged in the longitudinal direction, the lateral reinforcing portion does not hinder light reflection. When light is irradiated from the light source, the light is reflected toward the light source, and one light line can be visually recognized.

The garment reflection band of the present invention uses any one of a plurality of warps and wefts constituting the longitudinal reinforcing portion of the base material as a lateral reinforcing portion. Therefore, since the reflective tape can be woven when the base material is woven, its manufacture is simple. The lateral reinforcing part forms a ladder pattern, and when light is emitted from the light source, the light is reflected toward the light source and looks like a single line. Since the reflective tape is woven, the reflective surface is disposed at a position lower than the substrate surface. Therefore, the reflective surface is not easily exposed to friction and is not easily worn.

It is the figure which showed typically the planar view of one Example of the reflective band for clothes of this invention. It is the figure which expanded the cross section of the AA part of FIG. 1, and was shown typically. It is the photograph which irradiated the light to the reflective band for clothes of the present invention, and photographed recursion light. It is the photograph which image | photographed the state before irradiating light to the reflective band for clothes of this invention.

Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings. In FIG. 1, the planar view of one Example of the reflective band for clothes of this invention was shown typically. In FIG. 2, the cross section of the AA part of FIG. 1 was expanded and shown.

As shown in FIG. 1, the reflective band 1 for clothes of the present invention (hereinafter simply referred to as a reflective band) has a ladder pattern when viewed from a plane. Although not shown, a ladder pattern also appears when viewed from the bottom. A reflection band 1 in FIG. 1 includes a reflection tape 2 made of a strip-like retroreflective material and a base material 3 for fixing the reflection tape 2.

The base material 3 includes a pair of left and right vertical reinforcing portions 31 and 32 and a horizontal reinforcing portion 33 that connects the vertical reinforcing portions 31 and 32. In the case of a ladder, the vertical reinforcing portions 31 and 32 correspond to the vertical bars of the ladder, and the horizontal reinforcing portion 33 corresponds to the horizontal bars of the ladder. The longitudinal reinforcing portions 31 and 32 are composed of a woven fabric made of warp and weft, and the lateral reinforcing portion 33 is composed of either one of the warp and weft constituting the longitudinal reinforcing portions 31 and 32. The transverse reinforcing portion 33 of the reflection band 1 shown in FIGS. 1 and 2 is composed of a group of a plurality of wefts 4 constituting the longitudinal reinforcing portions 31 and 32, as shown in the sectional view of FIG. In FIG. 2, a plurality of wefts 4 extend from the right vertical reinforcing portion 32 on the back side to the left vertical reinforcing portion 31 on the front side. In FIG. 2, 16 wefts 4 form a group, but the number may be changed according to the fineness of the wefts. Further, the weft 4 may be woven by folding back one continuous yarn at the left and right ends of the woven fabric, or a plurality of wefts may be used. In the example of FIGS. 1 and 2, one continuous weft 4 is used, but in the cross-sectional view of FIG. 2, it looks like a plurality of wefts 4 for convenience of drawing.

As shown in the sectional view of FIG. 2, the surface of the reflective surface 21 of the reflective tape 2 is at a position lower in the thickness direction of the reflective band 1 than the surface of the base material 3 (reference numeral 32 in FIG. 2). When viewed from the back surface of the reflector 3, the reflector 1 is at a high position in the thickness direction. That is, since the reflective tape 2 is in a position reserved from the front and back surfaces of the base material 3, the reflective tape 2 is not easily worn by friction.

The reflective surface 21 and the lateral reinforcing portion 33 of the reflective tape 2 are alternately and continuously arranged in the longitudinal direction of the clothing reflective band 1. For this reason, when light is irradiated from the light source, the lateral reinforcing portion 33 is hardly visually recognized, and the retroreflected light from the reflecting surface 21 is visually recognized and looks like a continuous line of light. The reflecting surface 21 and the lateral reinforcing portion 33 may be squares having the same area, and the reflecting surface 21 and the lateral reinforcing portion 33 may be alternately arranged. If it does in this way, reflection of the light of the reflective surface 21 will not be prevented by the horizontal reinforcement part 33, but it will look like the line of one light by recursive light.

The base material 3 is woven using warp yarns. What is necessary is just a woven structure in which the warp or the weft constituting the base material 3 is arranged across the reflective tape 2. For example, a structure such as plain weave and twill weave can be adopted. As described above, the base material 3 is a woven fabric having a thickness larger than that of the reflective tape 2 so that the reflective surface 21 of the reflective tape 2 is positioned slightly lower than the surface of the base material 3. In the example of FIGS. 1 and 2, the warp is arranged along the longitudinal direction of the reflection band 1, but the weft may be arranged along the longitudinal direction by changing the longitudinal and lateral directions when weaving. In this case, the cross section is obtained by replacing the weft 4 indicated by reference numeral 4 in FIG. That is, a plurality of warps are arranged so as to be orthogonal to the longitudinal direction of the reflector 1, and the wefts are passed along the longitudinal direction. At this time, the warps are arranged so that a group of warps pass alternately through the front and back surfaces of the reflective tape 2 as shown in FIG. Since the weft is divided into the back side and the near side in FIG. 2 by the reflective tape 2 arranged along the longitudinal direction, two wefts are used when continuous wefts are used.

For the reflective tape 2, a retroreflective material in which a plurality of glass beads are arranged on the reflective surface or a prism can be employed. You may stick the reinforcement layer which consists of woven fabric etc. to the back surface of a reflective surface.

Hereinafter, the present invention will be described more specifically with reference to examples.

A reflective tape formed by fixing a plurality of minute glass beads on the reflective surface was woven into a base material using polyester wefts. The used reflective tape has a width of 1.0 mm, and a reinforcing layer made of woven fabric is stuck on the back surface. The thickness of the reflective tape is 0.3 mm including the reinforcing layer. A plurality of polyester warp yarns were arranged on both sides of the reflective tape, and polyester reinforcement yarns were also used for the weft yarns to weave the longitudinal reinforcing portions with twill weave. As for the weft, one woven yarn was folded back at the left and right ends of the woven fabric, and a plurality of groups of wefts were alternately passed through the front and back surfaces of the reflective tape as shown in FIG. The dimension per reflecting surface is 1.0 mm × 1.0 mm. Similarly, the dimension per one side reinforcement part is also 1.0 mm x 1.0 mm. The thickness of the base material woven in this way is 0.5 mm. The width | variety of a longitudinal reinforcement part is 1.2 mm per one.

The reflection band for the sailor garment manufactured as described above was cut into a length of about 30 cm, and three of them were arranged side by side and irradiated with light from a light source to photograph recursive light. The photograph is shown in FIG.

As shown in FIG. 3, it was confirmed that the lateral reinforcing portion did not hinder the reflection of light by the reflective tape, and one continuous light line appeared. For comparison, FIG. 4 shows a photograph of the state before light is emitted from the light source. When this reflective band for a sailor garment was sewn to a sailor garment, the reflective performance was not easily reduced by use or washing, and good reflective performance was maintained over a long period of time. Moreover, since the reflective tape is being fixed by the horizontal reinforcement part, the reflective tape did not peel from the base material and dropped off.
