Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a skirt-raising tape for pants, skirts, curtains, etc., which is made of a narrow-width knitting or woven tape (generally referred to as knitting tape in this specification).

[0002]

[Prior art]

 Conventionally, this type of skirting tape has generally been formed by knitting a heat-bonding yarn over a width of about 6 mm in both ears on the back side of a narrow tape generally knitted. And, in order to eliminate the shrinkage of the yarn itself and the residual shrinkage rate of the cloth caused by the tension during knitting, it is usually necessary to perform a rearrangement process called heat set on this coarse narrow knitting tape. It had been.

However, in the case of such a coarse knitting tape of the related art, since the heat fusion yarn is knitted as described above, the resin processing and the heat setting treatment cannot be sufficiently performed and the shrinkage rate is large. In the meantime, it didn't resolve. For this reason, in the case of conventional products, the precautionary statement for use always states that it should be immersed in water and squeezed lightly. Moreover, since the heat-sealable yarn is knitted into the knitted fabric having a relatively coarse mesh in the skirt-raising tape using the above-mentioned conventional knitting tape, a large amount of molten resin is generated when the heat-sealable yarn is melted during use. It will get into the gaps of the knitted fabric and hinder strong adhesion.

Originally, for ideal adhesion, the heat-sealing yarn should form a crosslinked body between the adherend of the trouser cloth and the skirt-raising tape cloth and evenly anchor the resin on both sides. Due to the roughness of the adherend, which is significantly higher than the back surface density, excessive exudation of resin into the tape fabric was unavoidable, and effective and strong adhesion could not be achieved.

Further, in the conventional tailing tape, a heat-sealing yarn is knitted and the adhesive effect is achieved by this fusion, but the knitted heat-sealing yarn has a structure in which a part of the heat-sealing yarn is a weft yarn. Also, since it is unavoidable that it is embedded in the cloth by the entangled yarn, only the chain-like portion exposed on the surface becomes the effective adhesive surface, and thus it was not possible to have a strong peel resistance.

[0006]

[Problems to be solved by the device]

 In view of the above-mentioned actual situation, the present invention pays attention to the construction of the base fabric of the tailing tape in order to cope with this situation, prevents the fusion resin from squeezing out, and prevents the fusion resin from excessively entering the tape fabric body. The purpose is to prevent infiltration and enhance adhesion performance and peel resistance.

[0007]

[Means for Solving the Problems]

 In order to meet the above-mentioned purpose, the present invention has a basic construction in which a heat-sealing resin film is heat-pressed to the rear surface of both ears of the narrow-width knitted woven tape forming the tape base over a required width. Further, according to the present invention, both ears of the narrow width woven tape are woven and woven into a dense structure over a required width, respectively, and the heat-sealing resin film is heat-pressed to the back side of the structure.

According to a third aspect of the present invention, in a more specific configuration, both ears of the narrow width knitting tape are knitted into a dense structure over the required widths, respectively, while the remaining middle part is knitted into a coarse structure that can be seen through. It is woven, and the heat-sealing resin film is thermocompression bonded to the back surface side of the dense tissue portion.

According to a fourth aspect of the present invention, a raised fabric is used instead of the dense tissue, and the narrow-width woven tape base fabric is composed of a single-sided raised fabric having raised fabrics on at least back surfaces of both ears, and the ears. A heat-sealing resin film is heat-pressed onto the raised surface.

Each of the inventions described in claims 5 and 6 relates to a preferred embodiment of the skirting tape described in each of the above claims, in which the former has a narrow width woven tape forming a base fabric of the tape, which is pre-shrink-stop processed. The latter is characterized by using a non-water-absorbing polyurethane resin film as the heat-sealing resin film.

[0011]

[Embodiment of the invention]

 Hereinafter, with reference to the accompanying drawings, embodiments of the skirting tape of the present invention will be described.

FIG. 1 is a view showing a surface state of a tape having a dense structure of both ears and a coarse structure of an intermediate part as an example of a skirting tape according to the present invention, and FIG. FIG. 3 is a sectional view of the tape of the present invention after heat fusion.

In these figures, T indicates a narrow-width knitted woven tape which is the base of the skirting tape, 1 and 1 ′ are both ears thereof, 2 is the remaining middle portion, and 3 is a heat-sealing resin film. Here, the narrow-width woven tape T is usually knitted or woven into a narrow-width tape shape using fibrous fibers such as rayon or synthetic fibers such as nylon and polyester having a relatively high melting point and exceeding 180 ° C. It is knitted by a known tape loom or a warp knitting machine such as tricot or Russell. In the figure, however, both ears 1 and 1'having a width of 20 to 30 mm and upper and lower 5 to 8 mm are intermediate. The intermediate part 2 is knitted into a coarse structure, in particular, a coarse structure which can be seen through the eye, by forming a fine structure by using a fine count thread and densely arranging the thread in comparison with the part 2. ing.

On the other hand, a resin film having a melting point of 120 ° C. or less, particularly 80 to 105 ° C. is used as the heat-sealing resin film 3 to be pressure-bonded, and the resin is provided on the back surface of both ears 1, 1 ′ of the textile tape T. The fusion is performed by thermocompression bonding at a temperature slightly higher than the lower limit of the melting point of the film 3.

Examples of the heat-melting resin having a relatively low melting point include polypropylene, polyethylene, ethylene / vinyl acetate copolymer, acrylic acid ester, unsaturated polyester, and various other resins such as low-melting point polyester and polyamide. Among them, a polyurethane functional resin film, for example, a Daicel Chemical Industries Co., Ltd. thermolite functional film 100 micron (melting point 80 to 90 ° C.) film is suitable because it does not have water absorbability. Target. When the heat-sealing resin film 3 is pressure-bonded, it is preferable that the knitted woven tape base cloth is subjected to shrinkage-prevention processing in advance in order to enhance the shrinkage stability of the base cloth. Arrangement processing such as heat setting is adopted as the shrinkage prevention processing.

Although the two ears 1, 1 ′ of the knitted fabric tape T are formed to have a relatively denser structure than the intermediate part 2, the knitted fabric tape having a single-sided raised fabric instead of the denser structure, for example, a single-sided raised fabric It is also possible to use a tricot knitted fabric. In this case, a tricot knitted fabric with one-sided brushing is subjected to a shrinkage-preventing process such as shrinking in advance, and then cut into tapes with a width of 20 to 30 mm, and the brushed surface on the back of both ears is roughly cut. It can be obtained by thermocompression bonding a heat-fusion resin film having a width of 5 mm.

By heat-pressing the heat-fusible resin film on the raised surface in this manner, it is possible to prevent the melted resin from excessively infiltrating into the textile tape body during use. The one-sided nap may be only the required parts of the back both ears 1, 1'to which the heat-sealing resin film is pressure-bonded, but may be naps over the entire surface in the production of the textile tape body.

The skirt tape produced as described above is folded back at the hem of trousers, a skirt, etc., is attached to a required joining site, and is further heated and pressure-bonded by a press, an iron, etc. so that the hem is fixed to the hem. The lifting work can be accomplished efficiently.

In addition, the skirt-raising tape of the present invention is not limited to the conventional usage in pants, skirts, etc., and one ears of both ears can be adjusted in advance by adjusting the hem length of pants, skirts, curtains, etc. After heat-sealing to one end of the adherend such as a skirt or curtain, fold back the bottom end of the adherend according to the length of the adherend and set the other ear at that position as a predetermined length. It is also preferable to use heat fusion bonding. In particular, when release paper is layered on the heat-sealing resin film, the release paper at one ear of the skirting tape is peeled off and removed from the bottom edge of pants, skirts, curtains, etc. Keep the hem tape attached only to the bottom edge of the adherend product.After the product is sold, adjust the hem length according to the usage conditions and leave the remaining tape at the specified position. By removing the release paper from the ears and applying heat and pressure, the hem can be easily adjusted to your liking.

[Effect of the invention]

 The tailing tape of the present invention is constructed as described above, and because it is surface-bonded by a heat-sealing film, it is more adhesive than the chain-line bonding of the one in which the heat-sealing yarn is woven or woven like the conventional product. Since the area is large and the adhesive strength is remarkably increased, a strong adhesive effect can be achieved. In addition, since the tailing tape of the present invention has both ears woven and woven in a dense structure with respect to the middle part and the heat-sealing resin film is pressure-bonded thereto, the heat conduction is good when heated from the surface and the heat-melting tape The resin does not excessively infiltrate into the tape body when the resin film is melted, and the adhesive effect can be sufficiently exhibited. The same applies when the heat-sealing resin film is pressure-bonded to the raised surface. Further, as described in claim 3, when the intermediate portion is made to have a transparent texture so as to be transparent, the cut edge line of the hem folded back can be visually recognized through the tape cloth body at the time of raising the bottom of the tape. It is easy to proceed with the bonding work by arranging so that the center of the is located at the cutting edge line and using a press iron. In addition, when raising the hem of the pants, there is a case where it is necessary to incline the back hem in a V-shape and lower it, but the present invention occupies about half the full width of the tape. Since the part has a very coarse structure, it is highly flexible, and it is easy to attach the tape to the desired curve. In particular, when a narrow-width knitted woven tape that has been processed to prevent shrinkage is used as the base material, it has excellent shrinkage stability, so that it can be efficiently worked by pressing, ironing, etc. without being soaked in water at the time of use. Do not wet or wet the adherend such as pants or skirts. The heat-sealing yarn woven into the conventional hem-wrapping tape is a water-absorbing nylon and is highly water-absorbent, so it does not escape natural contraction after bonding or when worn, which may cause a twitch in the bonded area. However, if a film made of polyurethane resin that does not absorb water is used as in claim 6, natural absorption does not occur because the film does not absorb water, and the stretchable surface fabric due to the elastic elasticity of polyurethane. Since it follows well, it has the special effect of being soft and difficult to peel off.
