Description

[Detailed explanation of the idea] The present invention relates to a sewing tape.

Conventionally, as a sewing tape, a heat-activated adhesive, a so-called hot melt adhesive (hereinafter simply abbreviated as hot melt) 3 is applied to a tape-like base material 1' surface as shown in FIG. 1 (plan view).
′ is applied to the entire surface of the sewing tape, but as shown in Figure 2, the stitched area obtained using this type of sewing tape is flexible because the hot melt 3′ exists in a continuous state. Disadvantages such as lack of water permeability in the seamed parts when washing sewn products, and especially when the sewn products are waterproofed, air and water tend to accumulate inside the sewn products, which hinders washing and dehydration. was there.

In the figure, 4' and 5' are cloths. Furthermore, when sewing two pieces of cloth together, a sewing tape is placed on one cloth 4', and when the other cloth 5' is placed on top of the tape, the sewing tape is misaligned.

The present invention aims to provide a new sewing tape that eliminates the above-mentioned drawbacks of the conventional sewing tape, namely, the lack of flexibility in the stitched portion and the tape's positional shift during stitching. An adhesive layer is provided, small lumps of heat-activated adhesive are adhered to the surface of the adhesive layer at intervals, and the adhesive layer is used to temporarily fix the tape to one fabric surface to be sewn. The small lump of the heat-activated adhesive is fused to the fabric surface by applying heat to the other side of the tape, and after this fusion, the tape is peeled off from the fabric surface together with the adhesive layer. It is characterized by being attached to the cloth surface.

The present invention will be described below based on embodiments shown in the drawings.

The invented tape is shown in Figure 3 (cross-sectional view) and Figure 4 (plan view).
As shown in the figure, an adhesive layer 2 is provided on one side of a polyester tape 1, and small lumps of a heat-activated adhesive, so-called hot melt 3, are dotted onto the adhesive layer 2 at intervals.

6 in FIG. 3 is a separator paper.

In the case of the above embodiment, the small lump of hot melt 3 is shown as being circular in the plan view, but the shape of the small lump is free.
It may also be rectangular as shown in FIG.

If it is circular, its diameter is 2 to 3 mm and the height is 50 to 150 mm.
In the case of a rectangular shape, it is preferable to have a width of 1 to 2 mm, a length of 2 to 5 mm, and a height of about 50 to 150 μ.

In addition, the arrangement of the hot melt 3 is as shown in Fig. 6.
They may be arranged in rows or in a zigzag arrangement as shown in FIG. 7, without any limitation.

In the present invention, since the adhesive layer is provided on the surface of the polyester tape, it is extremely easy to hold the hot melt lumps on the tape base material surface.

In addition to ethylene vinyl acetate copolymer, various types of heat-activated adhesives such as polyamide, polyester, and rubber are used as the heat-activated adhesive used in this invention, and tackifier resins, wax, etc. are added to these resins as necessary. The desired hot melt can be obtained.

Next, how to use the tape of the present invention will be explained.

FIGS. 8A, 8B and 8C are diagrams illustrating how to use the tape of the present invention.

As shown in FIG. 8A, after removing the separator paper of the tape, place the tape on the fabric 4 with the adhesive layer side of the tape of the present invention facing the 4 side of the fabric 4 to be sewn, and place the tape in a box. Apply iron H from one side of the ester tape.

Then, the hot melt 3 is heated and pressed by the iron H.
melts and adheres to the four surfaces of the cloth as shown in FIG. 8B.

In the above, when the sewing tape of the present invention is placed on the cloth 4, since the tape of the present invention is provided with two layers of adhesive,
Since the two layers of adhesive adhere to the cloth 4, the hot melt 3 can be accurately adhered to a predetermined position on the cloth 4 without the tape shifting. When the tape 1 is peeled off after this adhesion, the adhesive is removed along with the tape 1. The second layer is also peeled off from the fourth side of the cloth, and as shown in Figure 8B, a small lump of hot melt 3 is left on the fourth side of the cloth.
・Only will be attached.

Therefore, the other cloth 5 is placed on the cloth 4 to which the hot melt 3 is attached.
When they are overlapped and heated and pressed with an iron H, both cloths 4 and 5 are easily sewn together as shown in FIG. 8C.

When conventional thermal adhesive tape for sewing is used, as shown in Fig. 2, the hot melt 3 adhered to the cloth is continuous, so the hot melt 3 is cooled and solidified at the seamed portion, resulting in a lack of flexibility. However, according to the inventive tape, the 8th
As shown in FIG. C, since the hot melts 3 are arranged in a dotted line pattern at appropriate intervals, sewing with sufficient flexibility can be easily achieved as in the case of thread sewing.

In addition, when washing a sewn product, air and water inside the product can easily pass through the seams, even if the product is waterproof.
It effectively prevents air and water from accumulating inside the sewn product, making it easy to wash.
Dehydration can be performed well.

Furthermore, since the tape of the present invention is provided with an adhesive layer, when the tape of the present invention is placed on a cloth, the adhesive layer and the cloth adhere to each other, so that the tape can be placed at a predetermined location on the cloth without shifting. It has the advantage of being able to accurately attach hot melt to.

In addition, it is desirable to use polyester tape with excellent heat resistance as the tape base material, and according to Karu Tape,
The fabric is not damaged by the heat of the iron, and
After heating with an iron, only the polyester tape can be easily peeled off.
