Description

[Detailed description of the invention] (Industrial field of application) The present invention is a bandage (including a bandage that also doubles as a saparta, hereinafter the same) for protecting the affected area, specifically, it has longitudinal elasticity, breathability, The present invention relates to the above-mentioned bandage that has self-adhesive properties, is easy to tear, and is convenient to handle.

(Prior Art) Bandages have traditionally been made of gauze cloth or, more recently, knitted cloth knitted using a ratchet machine, to a predetermined length and appropriate width, and bandages that are stretchable in the length direction are also available. However, all of these bandages were usually fixed using a bandage stopper at the end of wrapping. Therefore, various studies have been made on fixing means, including bandage fixing.

However, when using a bandage stopper, the ends of the bandage cloth often fray, or the bandage stopper is often damaged and comes off during use.

Therefore, a method of bonding fabrics without using a bandage was researched, and one example of this was provided in Utility Model Application No. 4758/1983.

This is done by inserting and knitting connecting threads in a zigzag pattern between adjacent wale stitches of a warp wale stitch row consisting of multiple rows of required knitting yarns arranged in parallel over the required width, and then knitting the required knitting yarns into the base fabric. A mixture of natural rubber latex and synthetic rubber latex is sprayed onto the fabric, and the mixture is adhered to the fabric without blocking the stitches.

(Problem that the invention aims to solve) However, even though the bandage made in this way has excellent self-adhesion, it is necessary to use scissors etc. to cut it in the width direction. There were some difficulties in handling during use.

Moreover, conventional bandages made mainly of cotton that can be easily torn horizontally by hand have not been found, and if they were torn in this way, the ends of the threads would become disordered, which would be undesirable in terms of appearance, and would not be practical. It was not suitable at all.

The present invention deals with this situation, takes into account the above-mentioned defects, expands and contracts in the vertical direction, does not apply undue pressure, has excellent fitting properties, and has self-adhesive properties.
It is an object of the present invention to provide a bandage which can be easily torn by hand in the transverse direction, that is, in the width direction, by selectively arranging the fabric structure, particularly the warp and warp yarns, and which does not exhibit fraying at the yarn ends.

(Means for Solving the Problems) That is, the present invention is characterized by a relatively thin fabric made of a fine denier stretchable elastic yarn as a core and coated with cotton or other arbitrary fibers, preferably short fibers. The base fabric is a fabric in which high-count yarns are used as the warp yarns, while comparatively thick yarns made of cotton, synthetic fibers, etc. are used as the weft yarns to create a warp-cross weave structure, and this is mixed with mainly natural latex and synthetic rubber latex. By spraying the liquid, the mixed liquid is attached to the warp and warp yarns themselves and dried while maintaining air permeability without forming a film on the fabric surface.

Here, the warp used for forming the fabric is as follows:
A so-called covering yarn, in which a stretchable elastic yarn such as fine denier polyurethane elastic yarn or rubber yarn is used as a core yarn, and fibers such as cotton, soft cotton, or synthetic cotton, preferably short fibers, are coated around the core yarn. For kimono, the thickness is preferably around 40 to 60, while the weft is preferably a thick yarn, for example around 10, preferably spun yarn, especially cotton spun yarn.

However, in general, warp yarns need only be thin, have low elongation at break, and are easy to tear, while weft yarns can be thick, bulky, coatable, and strong. good.

Plain weave is the most common fabric structure using warp and warp threads, but it is not limited to this, and the thread rows are relatively coarse in warp threads and relatively dense in weft threads (depending on the thickness of the threads, Of course, even if the number of fibers per 1 mm is the same, the density will be high.

Next, if too much of the mixture of natural rubber latex and synthetic rubber latex is applied to the fabric, it will form a film and impede the air permeability of the bandage.

Also, if the amount is too small, the adhesiveness and durability will be poor, so select an appropriate amount.

Therefore, the solid content of both rubber latexes in the mixed liquid is usually about 15 to 200 g per 100 g of the bandage fabric.

The natural rubber latex to be used may be any commercially available one, and the synthetic rubber latex may be one with appropriate elongation and flexibility.
Butadiene rubber latex (SBR), acrylonitrile-butadiene rubber latex (NBR),
Polychloroprene rubber latex (CR) and the like are used, among which NBR is most suitable.

Note that synthetic resin emulsions and the like can also be used as long as they have properties similar to those described above.

By adjusting the blending ratio of natural rubber latex and synthetic rubber latex, it is possible to obtain the required adhesion and strength, but if you consider adhesion, breathability, elasticity, etc. It is preferable to mix more than natural rubber latex, about 6 to 8
A ratio of about 2 to 4 parts of synthetic rubber latex to parts of synthetic rubber latex is most practical. However, it is not necessarily limited to this.

In addition, when mixing the natural rubber latex and the synthetic rubber latex, a known antiaging agent and, if necessary, a coloring agent are also mixed in to prevent aging phenomena.

Although the mixture of natural rubber latex and synthetic rubber latex can be applied to the fabric by known means such as spraying or coating, the former is particularly effective.

(Function) The bandage of the present invention constructed as described above is made of a fabric using elastic threads that stretch in the warp direction, so it can be stretched in the warp direction, and it fits well on joints etc. . Moreover, if you press the fabric with your hand at the end of wrapping, the self-adhesive properties will allow the fabrics to adhere to each other, eliminating the need for a bandage.
Can be fixed.

Furthermore, when wrapping a bandage, no longer length is required, and when attempting to cut the warp threads, the warp threads can be easily torn apart without using scissors if the warp threads are torn apart in the width direction. Moreover, since the self-adhesive latex is sprayed onto the surface of the bandage fabric at this time and adheres thereto, the tissues of the fabric are sufficiently fixed and adhered to each other without fraying.

(Embodiments) Hereinafter, embodiments of the present invention will be further described based on the accompanying drawings.

FIG. 1 is a partially omitted enlarged view showing an example of the present invention, and FIG. 2 is a partially omitted overall overview.

That is, as shown in FIG. 2, the bandage of the present invention is made to have the required width and length like a normal bandage, and is easily portable.

The specific fabric structure is as illustrated in FIG. 1, with warp threads 1, 2, The required width is determined by the rows 3...n, and the warp yarns are appropriately woven with thick spun yarns b, woven into a plain weave in the figure, to form a woven fabric.

Then, a mixture c mainly composed of natural rubber latex and synthetic rubber latex is attached to each of the threads a and b, and the fabric structure is firmly fixed with air permeability without forming a film on the surface. .

That is, the mixture c penetrates into each of the yarns a and b constituting the base fabric, fixes the fibers constituting the yarn, and spreads into a part of the weave space formed by the warp and weft b, thereby improving air permeability. It provides adhesion without inhibiting.

Therefore, when using a bandage with the above structure to protect an affected area, simply pressing the bandage at the end of the winding will cause the fabrics to adhere to each other, making it easy to fix the end of the winding, and to protect the warp threads of fine count. The bandage fabric can be cut at any point by tearing it transversely.

(Effects of the invention) As described above, the present invention creates a fabric as a base material by cross-organizing the warp yarns of a predetermined row, which are relatively fine in count and are weak against tearing, and the weft yarns, and then adds natural rubber latex to this fabric.
A mixture of synthetic rubber latex is applied by spraying to give it self-adhesive properties, and it has the following effects over conventional bandages.

(a) Since stretchable elastic yarn is used for the warp threads, it has elasticity in the longitudinal direction, and has excellent fitting properties for protecting joints.

(b) Since it has self-adhesive properties, it can be fixed by simply pressing it at the end of the roll, and there is no need for a bandage.

(c) A mixture of both natural and synthetic rubber latex does not form a film on the surface of the base fabric and has a porous structure, so it has good air permeability and does not cause stuffiness at the wound.

(d) Although the bandage of the present invention is self-adhesive, it does not adhere to other things such as the skin, and is therefore extremely easy to handle.

(E) Since the warp of the bandage of the present invention is a fine-count thread that is susceptible to tearing, it can be easily cut at any point by tearing it in the width direction, and there is no need for special tools such as scissors. Therefore, it is easy and convenient to use.

Moreover, since the weft yarns are thick, the coverage of the fabric is good.In particular, since the mixed liquid is applied to the warp yarns over the entire surface, the tissue is firmly fixed, and even if it is torn by hand at any point, it will not cause any damage. The yarn ends are securely held and fixed without leaving loose threads or fuzz, and the appearance is not impaired.

In particular, if cotton fibers are used for both warp and warp yarns, a cotton bandage that can be easily torn in the width direction can be obtained, completely changing the concept of conventional cotton bandages, and making it possible to further enhance the effectiveness of using the bandage as a completely new cotton bandage.
