Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a reflective tape attached to a slide fastener or the like and a reflective tape therefor, and more particularly to a reflective tape having an improved light reflecting function and excellent morphological stability. And a reflective tape therefor.

[0002]

2. Description of the Related Art Conventionally, for example, a retroreflective film material that reflects light is woven or knitted on a part of the surface of a tape-like base cloth as a part of a constituent material of a woven thread or a knitting thread. Reflective tape is often used. This kind of reflective tape is directly produced as a fastener tape of a slide fastener which is attached to clothes, bags, or the like, or is produced as a reflective tape to be attached to the edge of a western umbrella or night construction clothes.

An example of a reflective fastener tape obtained by weaving a retroreflective slide fastener is disclosed in, for example, patent publication 284984 of the Republic of China. The reflective tape disclosed in this publication presses the retroreflective film material adjacent to the attachment portion of the fastener element with every few wefts, and exposes most of it over the longitudinal surface along the fastener element. It is made to be woven. As another example of the reflective tape, one side edge of the tape-shaped base cloth is woven into a hollow weave, and a single yarn obtained by slitting the reflective film material into a thin thread in this hollow weave portion is woven as a warp. The dull reflective tape is disclosed in, for example, Japanese Utility Model Laid-Open No. 4-7689.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The reflective tape disclosed in the above-mentioned Republic of China No. 284984 uses a thread-like retroreflective film material as a part of the warp, and after straddling several wefts. , Is dipped into the next weft and is woven by repeating this. For this reason, when the reflective tape is woven, the retroreflective film material that is not pressed down by the weft and is exposed to the surface across each weft floats above the weft due to the lengthening of the straddling portion. A gap is formed between the tape-shaped base fabric and the retroreflective film material.

When such a reflective tape is sewn on the other product, which is the adherend, the sewing machine needle catches on a part of the raised side edge of the reflective film material, thereby tearing the reflective film material. There is a problem that it is cut off by force or is pulled out from the ground structure forcibly, and a pulling portion is generated in the ground structure.
This is not limited to when the reflective tape is sewn. For example, even when the adherend is used, surrounding obstacles or fingernails are caught in the reflective film material, and the same problem occurs.

When a portion of the retroreflective film material is cut as described above, the cut portion is lifted up so as to warp above the weft. The raised tip portion also has a problem in that it is likely to be peeled off from the woven yarn of the reflective tape and fall off due to chain-like fraying. For this reason, it is impossible to exhibit the light reflecting function of the reflective tape after being commercialized for a long period of time.

Further, the reflective tape disclosed in Japanese Utility Model Laid-Open No. 4-7689 mentioned above is a tape in which a single yarn obtained by slitting a reflective film material into fine filaments is partially used as a warp as described above. It is woven into a hollow weave portion formed at one side edge of the base fabric. For this reason, the above-mentioned ROC 28th
Similar to the technique disclosed in Japanese Patent Publication No. 4984, the reflective film material is likely to be caught, cut, peeled or dropped, and the reflective film material can be stably attached to the surface side of the base cloth of the reflective tape. There is a problem that it cannot be fully exposed, and the light reflecting function of the reflective tape after being commercialized is not only lowered, but also the light reflecting function itself as the reflective tape may be lost. .

This is also the case when a woven or knitted structure in which the reflective film material does not float up is woven with, for example, a plain weave structure. If the reflective film material is pulled from the reflective tape by cutting or the like. When it is pulled out or dropped in some places, it loses its function as a reflective tape.

The present invention has been made in order to solve the above-mentioned conventional problems, and it is a reflective film material which is woven or knitted into a reflective tape after being commercialized and which is prevented from rising. It is a first object to provide an efficient and effective method for producing a tape, and further to provide a reflective tape which can exhibit an excellent light reflecting function for a long period of time and has excellent morphological stability. Is the second purpose.

[Means for Solving the Problems and Effects] The present invention
The invention according to claim 1 is a method for producing a reflective tape in which at least one surface of a tape-like base cloth is exposed and woven or knitted, and weaving or knitting the tape-like base cloth. Occasionally, the method includes arranging the heat-fusible threads along at least one side of the reflective film material and weaving or knitting them together, and heating and melting the heat-fusible threads. It is in a method for producing a characteristic reflective tape.

Here, as the reflective film material, a general narrow-width retroreflective film material, a luminous reflective film material, or the like is adopted. On the other hand, as the heat fusion yarn,
It is preferable that it is a colorless and transparent thermoplastic resin material having a lower melting point than the material of the tape-shaped base cloth and the reflective film material, and at the same time, has adhesive performance to the tape-shaped base cloth and the reflective film material. preferable. For that purpose, it is desirable to use the same type of resin as the constituent material of the reflective tape including the heat-sealing yarn.

The basic method for producing a reflective tape of the present invention is that the reflective film material and the heat-fusible yarns make up a set of yarns as a part of a weaving yarn or a knitting yarn, and Of the heat-fusible yarn is arranged along at least one side of the tape-like base fabric, and at the same time when the tape-shaped base fabric is woven or knitted, the heat-fusible yarn is woven or knitted together with the reflective film material to thereby be reflected. Manufactures the primary product of plastic tape. Next, the thermal fusion bonding yarn is heated and melted. By heat-melting the heat-melting yarn, the heat-melting heat-melting yarn is fused and integrated with the constituent yarns of the tape-shaped base cloth arranged on the side portions of the reflective film material and in the vicinity thereof. .

According to the present invention, at the same time as the weaving or knitting of the tape-like base cloth as described above, the heat-fusible yarn is woven or knitted along at least one side of the reflective film material. In addition, since the tape-shaped base cloth and the reflective film material are fused and integrated with each other by heating and melting the same heat-fusible yarn, it is not necessary to use another special fixing method, and the reflective tape is used. When weaving or knitting, the lifting of the reflective film material caused by the unique weaving or knitting structure can be reliably and completely prevented.

Therefore, when the reflective tape according to the present invention is sewn on an adherend, a sewing needle pierces the reflective film material,
When the reflective film material is cut or when an adherend to which the reflective tape is attached is used, the reflective film material is hooked on a nail or a peripheral member and strongly pulled to form a tape-shaped base cloth. There is no occurrence of dragging, peeling off or falling off from the tape-like base cloth.

That is, according to the present invention, the tape-shaped base cloth and the reflective film material can be easily fused and integrated with each other without using any special adhesion means for the reflective tape. It becomes possible to stabilize those forms, and it is possible to exert a reliable light reflecting function for a long period of time.

In the above description, the case where the heat-sealing yarn is woven or knitted along one side of the reflective film material is described, but the heat-sealing yarn is formed on both sides of the reflective film material. They may be woven or knitted at the same time. Further, the heat fusion yarn is not limited to a single yarn, but can be used in the form of, for example, a multifilament. Furthermore,
In the production of the reflective tape, the structure of weaving or knitting the reflective film material and the heat-sealing yarn is arbitrary, and for example, in order to expose the surface of the reflective tape, the number of weft yarns straddling the weft yarn is not always plural. Need not be, weft 1
It may be an organization that straddles books.

According to a second aspect of the present invention, there is provided a reflective tape in which a narrow reflective film material is exposed and woven or knitted on at least one surface of a tape-like base cloth, and the reflective film is provided. The reflective tape is characterized in that the tape-shaped base cloth and the reflective film material are fused and integrated via a fusion resin along at least one side of the material.

The reflective tape according to the present invention can be manufactured by the representative manufacturing method according to claim 1, but the invention is not limited to this. Regardless of its manufacturing method, the reflective tape of the present invention is extremely flexible and is finished as a reflective tape having a required rigidity. The basic structure of the reflective tape of the present invention is woven or knitted in a state where most of the reflective film material is exposed on at least one of the front and back surfaces of the tape-shaped base fabric, and the reflective film is Both the tape-shaped base cloth and the reflective film material are uniformly fused and integrated in the length direction along at least one side of the tape-shaped base fabric by the fusion-bonding resin disposed along at least one side of the material. Have been converted.

At this time, if the entire back surface of the reflective film material exposed on at least one surface of the tape-shaped base cloth is fused with a fusion resin, the flexibility of the reflective tape is impaired. By arranging the fusion resin along the side of the flexible film material, the fused portion of the reflective film material and the tape-shaped base cloth becomes a straight line with a broken line on the front and back, and the flexibility after fusion is also impaired. It will not be done.

Further, even though most of the reflective film material is exposed on one surface of the tape-shaped base cloth and is woven or knitted, the long exposed portion of the reflective film material is the tape-shaped base cloth. Without being lifted from one side, the reflective film material is stabbed with a sewing needle and cut at that part,
Alternatively, even if the reflective film material is caught due to interference with an external member, the woven or braided form of the reflective film material is stably maintained, and the quality of the reflective tape can be maintained for a long time.

In the invention according to claim 3, the fusion-bonding resin is
When weaving or knitting the tape-shaped base cloth, a fiber yarn made of a heat-meltable resin woven or knitted together with the reflective film material along at least one side of the reflective film material. It is characterized by being a molten resin of a strip.

In the present invention, the fusion-bonding resin is composed of a molten resin obtained by melting a fiber yarn made of a heat-meltable resin. As the molten resin, a monofilament or a multifilament made of a conventionally well-known general colorless and transparent thermoplastic resin material, or a fiber yarn obtained by cutting a thermoplastic resin film into a narrow width is used. When the monofilament, the multifilament, or the fiber yarn cut into the narrow width yarn is used as the fusion-bonding resin, the fiber yarn can be woven or knitted along the reflective film material, and the tape Both the base fabric and the reflective film material can be fused linearly and evenly. As a result, deformation of the reflective film material can be eliminated, and it can be visually recognized clearly even at night.

The invention according to claim 4 is characterized in that the melting point of the fusion-bonding resin is lower than the melting points of the constituent materials of the tape-shaped base cloth and the reflective film material. In this invention, if the heating temperature of the fusion-bonding resin is maintained at the melting point of the fusion-bonding resin or higher and the melting point of the constituent materials of the tape-like base cloth and the reflective film material or lower, only the fusion-bonding resin is obtained. Since it can be melted, a high quality and good reflective tape can be obtained without changing the physical properties of the tape-shaped base cloth and the reflective film material when the fusion-bonding resin is heated and melted.

According to a fifth aspect of the present invention, the tape-shaped base cloth, the reflective film material, and the fusion resin are made of a nylon-based or polyester-based resin material, and the fusion resin is made of another homogeneous resin material. Is characterized by being made of modified nylon or modified polyester having a low melting point.

In order to achieve the effects as described above,
It is important to select the most suitable material for the fusion resin. In the present invention, the tape-shaped base cloth, the reflective film material, and the constituent material of the fusion resin are composed of homogeneous materials, and the adhesive performance of the fusion resin to the tape-shaped base cloth and the reflection film material is secured. . As a typical thermoplastic resin material, a colorless and transparent nylon-based or polyester-based resin material is cited, and the melting point of the fusion-bonding resin material is lower than that of the constituent resin material of the tape-shaped base cloth and the reflective film material. Of modified nylon or modified polyester.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. FIG. 1 is an enlarged view of a main part schematically showing a reflective tape which is a first embodiment of the present invention. In the present embodiment, as the reflective tape to which the present invention is applied, a fastener tape of a slide fastener attached to an opening of clothes, a bag, or the like will be described as an example, but the present invention is not limited to this. It is not limited to all, but all reflective tapes applied to various products such as waist circumferences of clothes, cuffs and hem, collars of pets, shoulder belts of bags or edges of umbrellas.

In the figure, reference numeral 10 indicates a reflective tape which is superposed on the surface of the fastener tape 2 of the slide fastener 1 shown in FIG. According to the present embodiment, the reflective tape 10 is similar to the reflective tape shown in FIG. 2 of Japanese Patent Laid-Open No. 2000-70013 previously proposed by the present applicant, and the tape-shaped base fabric 11 thereof is used.
The main body is a sewn portion 11a to be attached to the fastener tape 2 by sewing or the like, and an enlarged edge portion 11b is integrally formed by a hollow weave along one side edge of the sewn portion 11a. The huge edge portion 11b is a reflection portion 11 that reflects light.
b.

The sewn portion 11a and the enlarging edge portion 11b of the tape-shaped base cloth 11 are woven by a needle loom using warp threads 12 and weft threads 13 of synthetic fiber threads made of a resin material such as nylon or polyester. Is made. The enlarged edge portion 11b formed along the side edge of the tape-shaped base cloth 11 is
It is configured by a hollow weave having the core material 14 inserted therethrough. As the core material 14, a monofilament or a multifilament made of a synthetic fiber of the same type as the constituent material of the tape-shaped base cloth 11 is used. In this embodiment, the tape-shaped base cloth 11 and the core material 14 are made of a nylon resin material, and the core material 14 is made of a thick resin wire.

A single piece of reflective film material 15 obtained by slitting the film into a narrow width is formed on the enlarged edge portion 11b.
Most of the are exposed on the surface. The reflective film material 15 is used as a part of the warp threads 12 of the hollow weave portion forming the enlarged edge portion 11b when the tape-shaped base cloth 11 is woven, and after straddling the three weft threads 13, The weft yarns 13 are interlaced with every other weft yarns 13 so that the weft yarns 13 are submerged, and the weft yarns 13 are woven in a substantially S-shape over the front and back surfaces of the core material 14 in the longitudinal direction at the same time as the tape-shaped base fabric 11 is woven.
In addition, in this embodiment, although the reflective film material 15 obtained by slitting is woven as a part of the warp threads 12, the present invention is not limited to this, and for example, the reflective film material 15 is used. Of course, it may be used as a part of the weft yarn, straddled over several warp yarns, and then woven so that the next-order warp yarn is dipped.

By the way, the tape-like base cloth 11 uses the reflective film material 15 as a part of the constituent yarns of the warp yarn 12 and is woven in a state of being pressed while intersecting with every several weft yarns 13. ing. Therefore, the reflective tape 1
When weaving 0, the reflective film material 15 which is not pressed down by the weft threads 13 and is exposed to the surface across each weft thread 13 has a long straddling portion. As a result, a part of the reflective film material 15 floats above the weft yarn 13, and a gap is formed between the tape-shaped base cloth 11 of the reflective tape 10 and the reflective film material 15.

When the reflective tape 10 finished in such a state is sewn onto the fastener tape 2 or when an adherend to which the reflective tape 10 is attached is used,
The reflective film material 15 is caught by a nail or other member and is strongly pulled to cause the tape-shaped base cloth 11 to be dragged or broken, or to be peeled off or dropped from the tape-shaped base cloth 11 to be originally You may lose the reflex function of.

Therefore, in the present invention, when the tape-shaped base cloth 11 of the reflective tape 10 is woven, the heat fusion yarn 16 is used.
Are woven along with the side portions of the reflective film material 15 together with the reflective film material 15 as warps.
After the reflective tape 10 is woven, it is heated at a temperature higher than the melting point of the heat-sealing yarn 16 and lower than the melting points of the other constituent materials of the reflective tape 10 to melt the heat-sealing yarn 16. The molten resin fuses and integrates the side portion of the reflective film material 15 and the constituent yarn of the tape-shaped base cloth 11 existing in the vicinity of the side portion.

The heat-fusible yarn 16 is woven as a part of the constituent yarns of the reflective tape 10 which is the object of the present invention, and includes the tape-shaped base cloth 11 and the reflective film material 15. It is necessary that the transparent fusing resin has a melting point lower than that of the constituent material. The reflective film material 15 is preferably a colorless and transparent thermoplastic resin material.

In this embodiment, a normal polyester resin is used as the film material of the tape-like base cloth 11 and the reflective film material 15 and the film material of the reflective film material 15, and the heat-bonding yarn 16 is made of the same material. A modified polyester having a lower melting point than the polyester resin is used.

It is preferable that a nylon-based or polyester-based resin material is used for the tape-shaped base cloth and the reflective film material in the present invention, and the heat-bonding yarn has the same quality as the tape-shaped base cloth and the reflective film material. Modified nylon or modified polyester having a melting point lower than that of the resin material is used.

As the reflective film material 15,
A metal such as aluminum, silver or copper is vapor-deposited, plated or painted on the base layer of the polyester resin to form a reflective film, and a polyvinyl glutar resin adhesive layer for glass is provided on the reflective film. A retroreflective film having glass beads adhered by an adhesive layer can be used.

Further, a phosphorescent layer is provided by coating SrAl ₂ O ₄ or the like as a phosphorescent pigment on a transparent polycarbonate resin film, and the surface of the phosphorescent layer is coated with an ink prepared by kneading titanium oxide with varnish such as acrylic resin. It is also possible to use a phosphorescent film having a reflective layer formed thereon.

Further, the reflective film material 15 may be a luminescent thread in which the fiber itself emits fluorescence. Fluorescent dye,
Alternatively, a luminescent thread dyed with a fluorescent white dye may be used to provide a luminescent function. Furthermore, a reflective function can be provided by weaving the fluorescent bleached reflective yarn as a part of the constituent material of the warp yarn 12.

The heat-fusible yarn 16 may be a spun yarn made of, for example, short fibers, and usually monofilament or multifilament is used. If the same kind of thermoplastic resin material is used as described above, good adhesive performance can be secured to the tape-shaped base cloth 11 and the reflective film material 15 in any case. The width and thickness of the reflective film material 15 can be appropriately set with respect to the tape-shaped base cloth 11, the cross-sectional form, the arrangement position, the number of arrangements, etc. It can be woven or braided so that it is exposed not only on the front surface but also on the back surface.

The reflective tape 10 thus obtained is fused to the constituent fibers of the reflective film material 15 and the tape-shaped base cloth 11 near the side edges in the width direction of the reflective film material 15 by melting the heat-bonding yarn 16. Since it is fused and integrated linearly with the wear,
Excellent flexibility is ensured even after the heat-sealing yarn 16 is fused, and the reflective film material 15 is prevented from rising and the morphological stability is ensured.

In order to manufacture the reflective tape 10 in a state where most of the reflective film material 15 is exposed to the outside on one surface of the expanded edge portion 11b, first, when the tape-like base cloth 11 is woven, the expanded tape material 11 is expanded. The reflective film material 15 having a narrow width at the edge portion 11b and the heat-sealing yarn 16 along one side of the reflective film material 15 are supplied together as one warp yarn.

The tape-shaped base cloth 11 has the enlarged edge portion 1
After the weft threads 13 of several (3 in the illustrated example) are straddled on the surface of the core material 14 of 1b, the next one weft thread 13 is dipped and woven by repeating this, and at the same time, the sewn portion 11a.
With a plain plain weave. As a result, the primary product of the reflective tape 10 is manufactured.

After weaving the reflective tape 10, the reflective tape 10 is heated at a temperature not higher than the melting temperature of the constituent materials such as the tape-like base cloth 11 and the reflective film material 15 and higher than the melting temperature of the heat-bonding yarn 16. Only the heat fusion yarn 16 is melted. When the heat-fusible yarn 16 is heated and melted in this manner, the side portions of the reflective film material 15 and the constituent yarns of the tape-shaped base cloth 11 existing in the vicinity of the side portions are melted by the heat-melted fusion resin 16a. The clothes are integrated.

FIG. 2 is an enlarged photograph of the reflective tape in which the tape-shaped base cloth 11 and the reflective film material 15 are fused and integrated by the fusion resin 16a. As is clear from the photograph, the fusion-bonding resin 16a is formed on the side edge of the reflective film material 15,
To the extent that the fused state is not clear, they are fused and integrated, and at the same time, the weft yarn 12 and the warp yarn 13 which are the constituent yarns of the tape-like base cloth 11 existing near the fused side edge of the reflective film material 15 are constituted. Some fibers are evenly fused and integrated.

As a result, the side edge of the reflective film material 15 exposed on the surface of the tape-shaped base cloth 11 and a part of the constituent yarns of the tape-shaped base cloth 11 are joined and integrated by the fusion resin 16a. Therefore, the reflective film material 15 is not lifted up, and the entire contact surface between the reflective film material 15 and the tape-shaped base cloth 11 is not fused by the molten resin, and the tape-shaped base is easily formed. The cloth 11 and the reflective film material 15 can be firmly fixed to each other.

When the entire contact surface between the tape-shaped base cloth 11 and the reflective film material 15 is fused with the fusion resin 16a, the flexibility of the reflective tape 10 is impaired. According to the present invention, as described above, the heat-fusible yarn 16 is arranged along at least one side portion of the reflective film material 15, and the heat-fusible yarn 16 is melted and fused to the side portion, whereby the reflective film is obtained. The fused portion between the material 15 and the tape-shaped base cloth 11 is fused in a broken line shape, and excellent flexibility and morphological stability can be secured even after the thermal fusion yarn 16 is fused. Therefore, the light reflecting function can be reliably exhibited for a long period of time. In order to improve the fusion bonding strength between the tape-shaped base fabric 11 and the reflective film material 15, the heat fusion threads 16 may be arranged along both left and right sides of the reflective film material 15.

Furthermore, since the side threads of the reflective film material 15 and the constituent threads of the tape-shaped base cloth 11 near the side areas are fused and fixed by the fusion resin 16a, the finished reflective tape 10 is covered. When sewing a kimono, even if the sewing machine needle pierces the reflective film material 15 and cuts the reflective film material 15, the reflective film material 15 separates from the tape-shaped base cloth 11, or Tape-shaped base cloth 1
It does not jump out from the surface of 1. When using the adherend to which the reflective tape 10 is attached,
Even if a fingernail or other member is caught on the reflective film material 15 and is strongly pulled, it is not easily pulled out, and it is stable without being stuck on the adherend. Therefore, it can withstand long use sufficiently. In addition, the heat fusion yarn 16 is
As shown in the figure, when the tape-shaped base cloth 11 is woven, it is arranged along one side of the reflective film material 15, but the present invention is not limited to the illustrated example.

It is woven. The woven structure of the reflective film material 15 and the heat-sealing yarn 16 is a structure in which, after straddling over two wefts 13 and then diving under the next weft 13, this is repeated and woven. The heat-fusible yarn 16 is such that the reflective film material 15 is interleaved between the warp yarns 12 of the ground structure in the main body of the tape-shaped base cloth 11.

At the time of weaving the tape-shaped base cloth 11, the thermal fusion bonding yarn 16 is simultaneously woven together with the reflective film material 15, and then the thermal fusion bonding yarn 16 is heated and melted. Also in the third embodiment, the constituent threads of the tape-shaped base cloth 11 contacting at the side portions of the reflective film material 15 and in the vicinity thereof are fused and integrated by the fusion resin 16a as in the above-described respective embodiments. Thus, the transparent reflective tape 10 is obtained.

The fusion resin 16a obtained by melting the core material 14, a part of the chain knitting yarn 21 adjacent to the core material 14, the weft insertion yarn 22 running on the surface side of the core material 14, and the side portions of the reflective film material 15
Through fusion.

The warp knitting yarn 20 is not limited to the illustrated example, and various knitting yarns such as a tricot knitting yarn, a double stitch knitting yarn, and a warp insertion yarn can be knitted. In addition, the reflective film material 15 and the heat fusion yarn 16
Is the same as each of the above embodiments in size, form, arrangement position,
The number of arrangements and the like can be set appropriately.

According to this structure, the reflective tape is exposed on the surface of the core material 14 even when the reflective film material 15 and the thermal fusion bonding thread 16 are woven between the wales of the reflective tape 10 by knitting. It is possible to prevent the exposed portion of 10 from rising and at the same time maintain desired flexibility and rigidity. The reflective film material 15 can be clearly seen through the stitches of the reflective tape 10, and the light reflection of the reflective film material 15 can be made to function extremely effectively.

The reflective tape 10 in each of the above-described embodiments configured as described above is arranged on the fastener tape 2 itself of the slide fastener 1 or on the surface of the tape 2 as shown in FIG. 6 and FIG. The enlarged edge portion 11b of the tape-shaped base cloth 11 is attached to the fastener element 3. The bulged edges 11b are attached with an interval corresponding to the thickness of the flange 4a of the slider 4, and the bulged edges 11b are raised on the surface of the fastener tape 2. Fasten the sewn portion 11a of the tape-shaped base cloth 11 to the fastener tape 2
Install on the surface of. In the figure, reference numeral 5 indicates an upper stopper of the slide fastener 1, and reference numeral 6 indicates a separable bottom end stop which is a lower stopper of the fastener 1. Further, reference numeral 8 indicates a sewing thread for sewing the fastener tape 2 and the reflective tape 10 to the product 7.

As is apparent from the above description, in the method of manufacturing the reflective tape 10 according to this embodiment, the reflective film material 15 and the heat-sealing yarn 16 are one of the constituent materials of the weaving yarn or the knitting yarn. As a part, the tape-like base cloth 11 is woven or knitted at the same time as weaving or knitting. The heat fusible threads 16 are woven or knit together along at least one side of the reflective film material 15. When the weaving or knitting of the reflective tape 10 is completed, the heat fusion yarn 16 is heated and melted, and the side portion of the reflection film material 15 and the constituent yarn of the tape-shaped base cloth 11 are fused and integrated with each other. Let Therefore, the floating of the reflective film material 15 caused by the unique woven structure or knitted structure is reliably and completely eliminated without using a special fixing method. Furthermore, when the reflective tape 10 is sewn to an adherend, even if the reflective film material 15 is cut by a sewing needle, the shape of the reflective film material 15 does not collapse, or when the adherend of the reflective tape 10 is used. Even if the reflective film material 15 is hooked and strongly pulled, the tape-like base cloth 11 is prevented from peeling off or falling off.

Further, the reflective tape 10 obtained by such a manufacturing method is woven with the reflective film material 15 with at least one surface of the tape-shaped base cloth 11 exposing the majority of the reflective film material 15 to the outside. The tape-shaped base cloth 1 is made of a fusion-bonding resin 16a which is woven and is arranged along at least one side of the reflective film material 15.
1 and the reflective film material 15 are fused and integrated, not only a good-looking reflective tape 10 having extremely excellent flexibility and morphological stability is obtained, but also the reflective film material 15 for a long period of time. The quality can be maintained, and a good light reflection function can be exhibited. The present invention is not limited to the above-described embodiments, and the reflective tape 10 may be directly produced as the fastener tape 2 of the slide fastener 1, for example,
As a matter of course, the technical scope that can be easily changed by those skilled in the art from the above-described embodiment is also included.
