JPS6026104Y2 - Adhesive tape for raising the hem of warp knitted fabric - Google Patents

Description

[Detailed description of the invention] This invention relates to an adhesive tape used for raising the hem of pants, etc.

Conventionally, when raising the hem of trousers, it is common to fold the edge of the fabric inward and join the folded edge of the fabric to the body by hand or machine stitching.

However, joining by this method requires great skill, and sewing threads often appear on the surface of the body, spoiling the appearance.

Also, the sewing thread is easy to break, and if it breaks while wearing it,
The joint in that area separates, causing extreme discomfort.

In recent years, devices have come into existence that use adhesive tape instead of sewing thread for these connections; for example, a device in which adhesive is applied to the entire surface of a fabric tape is known.

However, since this cloth tape is coated with adhesive over the entire surface, it is hard and does not have the ability to be placed on the tape.

Furthermore, since it has no elasticity, it cannot prevent wrinkles, that is, puckering, at the joint, so it cannot be used to raise the hem of pants, and its uses are extremely limited.

Furthermore, an adhesive tape made of a woven fabric in which heat-adhesive threads are inserted into a part of the woven fabric is known as Japanese Patent Publication No. 50-20488.

Since the woven fabric has no elasticity, this woven tape is characterized by having a weft-only part in the center of the tape, and by giving this part some slack, the above-mentioned puckering is prevented. .

However, this woven tape has a disadvantage in that it has a weft-only section to provide some slack, which makes the entire tape unbalanced and difficult to handle, and a weft-only section naturally has low strength.

Further, since the textile tape does not have elasticity as a whole, it is not preferable to join stretchable fabrics, such as knitted fabrics, because the elasticity of the knitted fabrics is destroyed.

Furthermore, when adhesive or heat-adhesive thread is used as the adhesive material, it hardens after adhesion, so if this part protrudes from the tape, the stockings may get caught when worn, causing damage to the stockings. Ta.

This invention solves the above-mentioned drawbacks of the prior art, and creates an adhesive tape that is particularly easy to handle, has appropriate elasticity, blends well with the joining fabric, does not cause puckering at the joint, and is strong. The purpose is to provide.

Another purpose is to improve the above-mentioned snags when worn.

In order to achieve the first objective, this invention has the following structure.

In other words, this invention is based on a tape-like warp knitted fabric in which the warp extends over adjacent wales to form a mesh in the non-stitched portions, and heat-adhesive yarn with a width of several wales is attached to both ends of the fabric in the warp direction. The tape-shaped warp knitted fabric is coated with heat-adhesive yarns, and the heat-adhesive yarns are applied to the tape-like warp-knitted fabric so that the heat-adhesive yarns are exposed on one or both sides of the warp-knitted fabric. This invention relates to an adhesive tape for hem-raising made of warp knitted fabric, characterized in that it does not come out from both ends.

In this invention, the heat-adhesive thread for imparting adhesive properties to the tape refers to threads that are melted by heat and have adhesive properties, such as nylon 6, nylon 66, and nylon 610. These fiber threads have the ability to melt and adhere by heat treatment at 120° to 180° C.

Therefore, it can be easily processed by heating with an iron or the like.

In addition, in this invention, the term "yaw weave" in which the warp threads straddle adjacent wales and form a mesh in the part where no stitches are formed refers to a dense closed weave with virtually no mesh or perforations. be.

In other words, in a warp-knitted fabric, after the warp threads of adjacent wales form a stitch, a mesh or transparent pattern is created by partially providing a portion where the warp threads of adjacent wales cross each other to prevent the formation of a stitch in the other wale. It refers to something with a hole.

For example, mesh knitting in which one or several courses of adjacent stitches form a mesh by unconnected parts, chain knitting and tapestry knitting in which the stitches are formed by a person who shakes the weft, or warp yarns forming a stitch in adjacent wales that are connected to each other. It is possible to apply a so-called shaya knit method, in which no knits are formed in the wales, and the underlap between the wales is entwined to form a through hole.

This invention will be explained below with reference to the drawings.

FIG. 1 is a schematic front view of one side of the adhesive tape of this invention.

In this invention, the heat-adhesive yarn 2 is attached to both edges of the warp knitting tape 1 so that it is applied to the width of several wales of the knitted fabric on one side as shown in the figure, or on both sides. ,
One thermoadhesive yarn 2 is wrapped on the left and right sides of one wale and inserted mainly in the vertical direction, or
It may be horizontally swung in a width of several wales.

The heat-adhesive yarn 2 is preferably arranged in a second reel and supported every few courses or every few wales by the warp yarn of the first reel, during which time it is suspended on the surface of the warp knitted fabric. .

In this way, by supporting the thermoadhesive yarn every few courses or wales, and shaking it from side to side while floating on the surface of the warp knitted fabric, the thermoadhesive yarn shrinks during bonding. However, there is sufficient room for shrinkage without affecting the soil structure.

Moreover, since it is swung from side to side, the area occupied by the thermoadhesive thread can be increased.

Therefore, the warp knitting tape 1 can sufficiently adhere to the target fabric.

Next, FIGS. 2 and 3 are partial or overall views showing a specific knitting structure according to this invention.

FIG. 2 shows an example of this invention, and is a partial view showing one end of the warp knitting tape 1.

However, the other end is also formed by this example end and the target tissue.

In Fig. 2, the four heat-adhesive yarns 2 on one side are guided in the second reel, are wrapped on the left and right sides of one wale, are laid in the warp direction, and are guided in the first reel. Thread 3
It is partially supported every few courses, and in between, it is floating on one side of the warp knitting tape 1.

The yarn 4 guided into the third reel is swung horizontally at an interval of two wales, and the chain stitches of the yarn 3 are connected to form a rectangular mesh.

This mesh portion exhibits an appropriate elasticity or play effect, and prevents puckering when used to raise the hem of pants, etc.

In addition, since the tape has a well-balanced structure as a whole, the tape as a whole is well-balanced and easy to handle despite the effect of play as described above, and can maintain sufficient strength.

Furthermore, the chain stitch can suppress elongation in the warp direction, increasing stability.

Furthermore, since the heat-adhesive threads 2 are arranged so as not to come out from the side edges of the warp knitting tape 1, the resin will not protrude from the tape after adhesion and will not get caught on stockings or the like.

FIG. 3 shows the entire knitting structure of yet another example of this invention, which is particularly intended to maintain sufficient play and strength in the center.

Figure 3 shows the entire width and part of the longitudinal direction of the warp-knitted tape 1, and the five heat-adhesive yarns 2 on one side, which are guided through the second reel, are wrapped on the left and right sides of one wale, respectively. , the thread 5 and 2 are laid in the warp direction and guided in the first direction.
It is supported by each course, and is floating on one side of the warp knitting tape 1 in between.

The threads 5 introduced into the first reel are alternately pulled out only in the center, and the threads 6 introduced into the third reel are pulled out alternately, making two threads. Step 3: Form a chain stitch of the same wale using the yarn 5, then change the direction and form a stitch with the chain stitch of the adjacent wale of 2 wales again, and further,
Change direction and return 2-3/1-0/1-0/2-3
Repeated wrapping is performed.

Furthermore, the yarn 7 introduced into the fourth reel is swung horizontally with a width of 5 wale lengthwise and two courses, and the yarn 8 introduced into the fifth reel is swung horizontally with a width of 5 wales and two courses. Only on both edges where the cloth is inserted are two wefts in the width and one course in the warp.

The warp-knitted tape 1 shown in FIG. 3 has a central portion formed by chain stitching by yarns 5 and twisting inlets 7 to form a square mesh shape, and this central portion has a play effect.

Furthermore, since the yarn 6 connects adjacent stitches while forming stitches simultaneously with the chain stitch yarn 8, the strength of the tape can be increased. Effectively prevents cracking from the tape or loosening of threads from the ends when cutting the tape.

Next, Figures 4 to 8 show the overall structure of the knitted tape for each row, which has been developed in this invention to prevent the stitches from loosening or cracking from the cut edge of the tape, and to increase its strength. be.

○ indicates that the thread is guided, and × indicates that the thread is removed.

The warp knitting tape shown in FIGS. 4 to 8 is one in which one warp knitting tape is knitted with one pot of needles.

Figure 4 shows that the thread 9 introduced into the first reel is 0 on all needles.
It is shown that a chain stitch is formed by wrapping of -1/1-0.

Figure 5 shows the wrapping of the thermally adhesive yarn 2 that is guided into the second loop. Five yarns are guided on each edge of the tape so that they do not come out from the tape side edges. 0-0/1-1 /1-1/1
-110-010-0 wrapping, each three courses is supported by the first reed chain knitting yarn 9, and is floating on one side between them.

In Figure 6, the thread is introduced into the third reel and only the two ends are pulled out, 2-3/1-010-1/1-0/2-3/
It is organized with a 3-2 wrapping.

This thread 10 is applied to the first thread in the same wale every three coats.
After forming a stitch at the same time as thread 9 of the reed, change the direction and
The wale is configured to be connected to the & and S of the adjacent wale, and as in the case of Fig. 3, this thread 10 increases the strength of the tape and prevents the stitches from coming loose or cracking from the center of the tape. , effectively prevents threads from becoming unraveled.

In Figure 7, the yarn is introduced into the fourth reel, and only the three ends are removed, and the stitches are not made with 0-0/4-4/3-3/4-4 wrapping. has been done.

This yarn 11 forms a square mesh with the chain stitches of the first and third reeds, gives the tape an appropriate play, and balances the warp and width of the tape. It is reinforced.

In Fig. 8, the yarn is introduced into the fifth reel, and only one of the ends is removed, and the yarn is wrapped with 2-210-0 without making any stitches.

This thread 12 also balances the length and width of the tape.
This reinforces the tape.

The warp knitted tapes with the structures shown in Figs. 4 to 8 are as follows.
5. By the threads 10, 11, and 12 which are guided in the reel,
There are adhesive tapes that form a square mesh on the tape, at the same time serve to reinforce and balance the tape, and are extremely easy to handle without unraveling or cracking from the cut end of the tape.

In the adhesive tape according to this invention, it is desirable to use thermoplastic synthetic fiber filaments such as polyester or polyamide for the yarns other than the thermoadhesive yarns in terms of strength.

However, thermoplastic synthetic fiber filaments are usually 1
Since it has a boiling water shrinkage rate of nearly 0%, the entire tape will shrink due to heating during adhesion, which is undesirable.

Therefore, thermoplastic synthetic fiber filament yarns are processed with heat treatment to reduce boiling water shrinkage to 3%.
You need to know the following.

Examples of processing involving heat treatment include a known method of reheating after tying, or a method of rolling the cheese in a relaxed state after tying and dyeing the cheese.

In this design, polyester synthetic fiber 75 denier 3
The boiling water shrinkage rate of the yarn obtained by temporarily twisting the 6 filaments, then dyeing them in a cheese state and dyeing them in boiling water is less than 1%.
The result is an extremely stable and flexible vertical adhesive tape.

For even more flexibility, 50 denier, 30 denier
Denier multifilament may also be used.

As mentioned above, since the adhesive tape of this invention has a warp-knitted structure, it has flexibility and appropriate elasticity, and it adapts well to both woven and knitted materials, and allows for different joints to be formed. There is little sense of harmony.

Furthermore, since it is possible to provide play in the center of the adhesive tape without weakening its strength, it is possible to prevent puckering at the joint, and at the same time, it is extremely stable.

Furthermore, since the entire tape is well-balanced, it has excellent effects such as easy handling, and stockings etc. do not get caught when worn.
