Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cloth tape having a moderate elasticity that can follow the expansion and contraction of cloth when sewn to clothes such as a trainer as a decorative tape, and relates to a woven label that can follow the expansion and contraction of cloth when sewn to the back side of clothes.

[0002]

[Prior art]

 For sportswear such as trainers and ski wear, there are products that have patterned woven or printed tape sewn on cuffs and shoulders for decoration. This type of decorative tape is woven into a tape shape by a narrow needle loom, or a high-speed loom such as a rapier loom with high production efficiency, and a wide woven fabric is woven with synthetic fiber yarn. It is manufactured by heat cutting. Recently, decorative tape has been partially sewn on not only sportswear but also young fashionable outer garments.

On the other hand, a woven label indicating a brand name, a manufacturer name or the like is sewn on the back side of clothes in almost all textile products. This woven label can be woven in a tape shape using a narrow-width needle loom as in the case of decorative tape, or a wide woven fabric can be woven using a repia loom, and the wide woven fabric can be heat-cut into strips, and then each label can be used. What is necessary is just to shred and manufacture.

[0004]

[Problems to be solved by the invention]

 The above-mentioned woven tapes and labels can be manufactured at a lower cost by using a high-speed loom such as a rapier loom and weaving a large number of wide woven fabrics at the same time, but in a rapier loom, warp and weft yarns are tightly woven tightly. By doing so, the obtained woven tape has no stretch in the longitudinal direction at all. For this reason, when the woven tape or label is sewn onto clothing, it cannot cope with the expansion and contraction or bending of the clothing fabric, and when the wearer extends his arms forward or bends his neck. The wearer feels that the clothes are pulled, and the comfort of the clothes deteriorates.

[0005] In particular, when this type of woven tape is sewn to the cuffs and shoulders of sportswear such as a trainer, the knitted fabric of sportswear has high elasticity. Feeling worse. Sportswear can perform comfortable exercise by greatly expanding and contracting or bending the fabric according to the movement of the wearer. Not only does the wearer feel uncomfortable or uncomfortable, but also restricts the wearer's movements and adversely affects the wear's durability.

The present invention has been proposed in order to improve the problem of elasticity of the conventional woven tape or woven label. It is intended to provide a cloth tape that is possible. Another object of the present invention is to provide a woven label that can expand and contract in accordance with the expansion and contraction of sewn clothing fabric.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the stretchable cloth tape according to the present invention is subjected to thermal processing of a long dent or ridge in the tape crossing direction, and the dent or ridge is spaced at predetermined intervals in the longitudinal direction. Formed repeatedly. The cloth tape of the present invention includes a woven tape and a print tape, and has elasticity because the dents or ridges recover from deformation when pulled in the longitudinal direction.

[0008] In other words, the cloth tape of the present invention is made of thermoplastic fibers that can be heat-processed. To manufacture this cloth tape, a regular flat tape material is aligned in parallel and sent to a gathering machine, where a part of the tape material's production is sandwiched by crossed heating blades and thermally deformed. After forming a narrow dent or ridge, the tape material is intermittently fed to form the dent or ridge repeatedly at predetermined intervals in the longitudinal direction.

In the stretchable woven label according to the present invention, a dent or a ridge elongated in the width direction is subjected to heat processing, and the dent or the ridge is formed repeatedly at predetermined intervals in the longitudinal direction. This woven label is made by cutting the heat-processed woven tape one by one and then bending a part of the woven tape. When the woven tape is pulled in the longitudinal direction, the dents or ridges recover from deformation, and have elasticity.

[0010] In other words, the woven label of the present invention is made of thermo-processable thermoplastic fiber. In order to manufacture this woven label, normal flat tape material is aligned in parallel and sent to a gathering machine, where a part of the tape material is sandwiched between crossed heating blades and thermally deformed. Thus, after forming a narrow dent or ridge, the tape material is intermittently fed to form the dent or ridge repeatedly at predetermined intervals in the longitudinal direction. Furthermore, the heat-processed woven tape is cut into individual pieces and then partially bent.

[0011]

[Embodiment of the invention]

 The cloth tape 1 (FIG. 1) according to the present invention may be a so-called woven tape or a print tape, and the print tape means a pattern in which a pattern such as a character is printed on a plain tape. The cloth tape 1 can be used as a decorative tape as long as an appropriate pattern is woven, and the tape material 18 (FIG. 4) is further cut and then partially folded to form a woven label 26 (FIG. 5).

If the cloth tape 1 or the tape material 18 is a thermoplastic fiber that can be heat-processed after weaving, polyester, nylon, polypropylene, polyethylene, polyvinyl chloride, polyvinylidene chloride, polyvinyl chloride, vinylon, acrylic Any of synthetic fibers such as fibers, semi-synthetic fibers, and blends of these fibers may be used, but polyester fibers are often used in terms of dyeability and cost. In the cloth tape 1 or the like, a portion where the dents 12 and the ridges 16 are not formed may be woven with a non-thermoplastic fiber weft.

As shown in FIGS. 1 to 3, the cloth tape 1 or the tape material 18 is formed by thermally processing a narrow or narrow dent 12 or ridge 16 in the tape cross direction. Are repeatedly formed at predetermined intervals. The planar shape of the dents 12 and the ridges 16 may be either a simple straight line, a waveform as shown in FIG. 1 or a zigzag shape as shown in FIG. Surface shapes are also possible. Further, the depressions 12 and the ridges 16 can be arranged discontinuously in the tape crossing direction.

The gathering machine 5 used in the present invention has a shape as shown in FIGS. 6 and 7. The gathering machine 5 includes a pair of elongated mold blades 7 and 7 for heating the tape material 2 to a temperature at which the tape material 2 can be thermally deformed. The mold blades 7, 7 have a slight gap in the opposing surface when not processing, and can horizontally move in a direction approaching each other during processing. It is preferable that the pressing die 8 is made of an elastic material such as a sponge so that a part of the tape material 2 can be pressed between the facing surfaces of the die blades 7, 7 when the pressing die 8 is lowered.

When the tape material 2 is fed to the gathering machine 5 with the tape material 2 facing upward, a recess 12 can be formed (see FIG. 2), and when the tape material 2 is turned upside down, a ridge 16 can be formed (see FIG. 3). If the mold blades 7 and 7 are not moved in the longitudinal direction, they will have a parallel continuous concave pattern as shown in FIG. 1, and if they are changed in the longitudinal direction at every pitch, every other one as shown in FIG. Thus, a continuous concave pattern is formed, and the variation of the pattern can be increased.

The gathering machine 5 intermittently feeds the tape material 2 and heat-processes the dents 12 or the ridges 16, and the feed amount is appropriately set as the distance L (FIG. 1) or the distance M (FIG. 4). Can be changed. By adjusting the feed amount, various concave patterns can be formed.For example, when the feed amount is large, the uneven pattern is small and the elasticity is small, and when the feed amount is small, the concave and convex patterns are superimposed on each other to form a complicated pattern. .

[0017]

【Example】

 Next, the present invention will be described based on embodiments, but the present invention is not limited to the embodiments. FIG. 1 illustrates a cloth tape 1 according to the present invention.

In order to weave the tape material 2 (FIG. 6) for the cloth tape 1, a pattern weaving mechanism combining a needle loom and a Jacquard machine operating at high speed with warp and weft of polyester yarn is used. In this pattern weaving mechanism, more than a dozen tape materials 2 with woven ears can be woven at the same time, and the weaving structure is plain or satin weave. The pattern of the tape material 2 is, for example, a pattern 3 (FIG. 1) of kana characters arranged in the vertical direction.

The woven tape material 2 is taken up on a reel 4 and sent to a gathering machine 5 shown in FIG. The gathering machine 5 has a pair of elongated mold blades 7 and 7 that heat to about 150 ° C., and a sponge press die 8 is installed above the both mold blades so as to be able to move up and down. The mold blades 7, 7 have a slight gap in the opposing surface when not being machined, move horizontally in the mutually approaching direction when being machined, and can be appropriately repositioned in the longitudinal direction. The opposing surfaces of the mold blades 7 have a planar shape according to the concavo-convex pattern to be formed, for example, a corrugated flat surface is provided (see FIG. 7). In each mold blade 7, the upper part 10 of the opposing surface is made to protrude upward with a small width. Each mold blade 7 has a length of 1500 mm and a width of 100 mm, for example, and can simultaneously heat many tape materials 2 arranged in parallel.

As shown in FIG. 7, a plurality of tape materials 2 are aligned in parallel and sent onto the mold blades 7, 7 of a gathering machine 5. At this time, thin paper (not shown) is combined with the tape material 2. The tape material 2 is interposed between the mold blades 7 to prevent the tape material 2 from being thermally damaged. When the tape material 2 is positioned on the mold blades 7,7, the pressing die 8 made of sponge descends and pushes a part of the tape material 2 between the opposing surfaces of the mold blades 7,7. , 7 horizontally move toward each other (see arrows in FIGS. 6 and 7). When the mold blades 7, 7 sandwich a part of the tape material 2, the press mold 8 moves up. Since the mold blades 7, 7 are heated to about 150 ° C., the clamped portion of the tape material 2 is thermally deformed to form a corrugated recess 12 as shown in FIG.

In the gathering machine 5, the mold blades 7, 7 are opened after the clamped portion of the tape material 2 is thermally deformed, and the tape material 2 is intermittently transported in the longitudinal direction. This transfer distance is a length L (FIG. 1) in the direction of the arrow in FIG. Hereinafter, the above process is repeated, and the corrugated dents 12 are repeatedly formed in the tape material 2 as shown in FIG.

The cloth tape 1 shown in FIG. 1 has elasticity because the concave 12 recovers from deformation when pulled in the longitudinal direction. The cloth tape 1 has a slight elasticity of several percent elongation, and can follow expansion and contraction of the trainer as a decorative tape or the like.

In order to manufacture the woven tape 15 shown in FIG. 3, the tape material is turned over and fed into the gathering machine 5. The gathering machine 5 forms the corrugated ridges 16 at the portion where the tape material is clamped, and when the tape material is intermittently transported in the longitudinal direction, the corrugated ridges 16 are repeatedly formed on the woven tape 15.

The label tape material 18 shown in FIG. 4 is manufactured after weaving a wide fabric (not shown) using ordinary polyester yarns for warp and weft. For weaving the wide fabric, for example, a pattern weaving mechanism combining a high-speed rapier loom and a Jacquard loom is used. The wide woven fabric has a weave structure of a plain or satin weave and a width of about 120 cm. The pattern of the wide woven fabric is a pattern 19 of English characters arranged in a straight line in the vertical direction according to the tape material arranged in a strip shape.

A large number of tape materials 18 are simultaneously manufactured by heat-cutting the above-mentioned wide woven fabric in a strip shape along a predetermined cutting line, and a fiber-melted portion due to a heat cut is generated on both side edges thereof. The fiber fusion part of the tape material is formed, for example, during heat cutting by a large number of heating knives or ultrasonic cutters attached to a rapier loom, and the ultrasonic fusion machine can make the fiber fusion part thinner.

The fiber fusion parts on both edges of the tape are preferably covered with the single-ring stitched parts 20, because they may deteriorate the feel of the label and damage the skin of the wearer. In an edge stitching device (not shown) for forming the single-ring stitch portion 20, the tape material is fed to the first sewing machine, and the feeding direction is opposite to that of the second sewing machine. In the first and second sewing machines, the presser disk is rotatably supported by an arm projecting obliquely downward and forward from above the front surface of the sewing machine.

In this edge sewing device, a reel of the tape material 18 is placed on a circular seat of a mounting table, the tape material 18 is pulled out from the core, and is conveyed horizontally by a guide member. With this guide member, the tape material 18 standing in the longitudinal direction is fed to the first sewing machine to accurately position the tape material, and while the tape material is intermittently sent to the left by the presser disc, one of the single-ring sewing portions 20 is interposed. To form. The tape material 18 having one edge sewn is taken in a horizontal direction through a guide member and a roller pair, and is further fed out in a horizontal direction by a roller pair and a guide member. The tape material 18 stands on the vertical roller in the longitudinal direction, and at this time, one of the single ring stitch portions 20 is located on the lower side. Further, the tape material 18 is fed to the second sewing machine by the guide member, and the other single-ring sewing portion 20 is formed while being intermittently fed to the right by the presser disc. The tape material 18 whose both side edges are sewn is taken up by a pair of rollers and wound on a reel below the table.

In the obtained tape material 18, on both side edges, one sewing thread forming each of the single-ring stitch portions 20, 20 intersects the fiber fusion portion on the side edge of the tape. The stitches are continuous without the seam being polymerized, and the thinned stitches closely cover the fiber fusion portion.

The tape material 18 is sent to a gathering machine similar to that shown in FIG. This gathering machine is provided with a pair of elongated mold blades which are heated to about 150 ° C., and the two mold blades are displaced in the longitudinal direction for each processing, and the opposing surfaces are formed in a zigzag plane. Each mold blade has a length of, for example, 1500 mm and a width of 100 mm, and can simultaneously heat many tape materials 18 arranged in parallel.

When the tape material 18 is positioned on the both blades, the pressing die made of sponge descends and pushes a part of the tape material between the opposing surfaces of the both blades. A part of the tape material is sandwiched, and then the stamping die rises. Since both the blades are heated, the clamped portion of the tape material 18 is thermally deformed to form a zigzag recess 22 as shown in FIG. In this gathering machine, both the blades open after the clamped portion of the tape material 18 is thermally deformed, and the tape material 18 is intermittently transferred in the longitudinal direction by a distance M (FIG. 4). It moves slightly horizontally in the longitudinal direction. Thereafter, the above-described steps are repeated, and the zigzag-shaped recess 22 is repeatedly formed in the tape material 18 as shown in FIG.

Next, at the alternate long and short dash line 24 in FIG. 4, the tape material 18 is heat-cut laterally for each character pattern by a cut-and-hold machine, and both ends are end-held in a subsequent bending process. A desired woven label 26 is made. The tape material 18 may be subjected to resin processing in advance, and may be end-held in a subsequent bending step and then pressed afterward.

[Effect of the invention]

 The cloth tape according to the present invention is a woven tape or a print tape provided with a slight elasticity, and can follow the expansion and contraction of cloth such as sportswear when sewn as a decorative tape. The cloth tape of the present invention can be sewn to the cuffs and shoulders of sportswear such as trainers, etc. Does not adversely affect durability.

The cloth tape of the present invention can be cut into a woven label by cutting it in the lateral direction, and a woven label having some elasticity can be obtained. When sewn to the back side of clothing, this woven label can respond to expansion and contraction or bending of the fabric, and does not cause the clothing to be pulled when the wearer bends his neck forward or extends his arm.

The cloth tape according to the present invention is obtained by weaving a large number of cloth tapes from a wide-width fabric using a high-speed loom such as a rapier loom so that a beautiful cloth tape with a pattern can be produced at very low cost. A slight elasticity can be imparted to the cloth tape. On the other hand, although stretchability itself is very high in conventional stretch fabrics, stretchability itself cannot be imparted to patterned fabrics due to strong thread tension during weaving.
