Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a stretchable self-adhesive bandage having no thread fraying and having hand-cutting properties.

[0002]

[Prior art]

 One type of bandage is a bandage that is elastic and self-adhesive. This type of bandage uses elastic yarn for the warp and cotton for the weft. The elastic yarn of the warp gives the stretchability of the bandage, and the rubber latex is attached to the surface of the warp and the weft. It has self-adhesiveness, so that it can be fixed by lightly pressing the end after winding.

However, there are several kinds of bandages, and these bandages are made by cutting a wide woven cloth into a predetermined width. For this reason, the thread may be unraveled from the cut portion, and it is difficult to wind due to the unraveling of the thread, and moreover, it impairs aesthetics, which is an obstacle when it is used in hospitals.

Some bandages are knitted with a knit base yarn, but since this is a knitted fabric, there is no fraying of the yarns, but the yarns are intricately entangled with each other and the hand tearability is poor. Since scissors must be used, the efficiency of the bandage procedure is also poor. Moreover, wrinkles are generated when the yarn is entangled due to knitting, which causes dryness and adversely affects the skin.

[0005]

[Problems to be solved by the device]

 The present invention aims to improve these points, eliminate the fray of the thread, have an appropriate hand-cutting property, and provide a good bandage for the skin.

[0006]

[Means for Solving the Problems]

 According to the present invention, a self-adhesive composed mainly of rubber latex is attached to a cloth woven with warp and weft, non-elastic yarn and elastic yarn are used for the warp, and non-elastic yarn is arranged for the weft. The breaking strength of the warp is set to about 50 to 300 g, the breaking strength of the warp is made weaker than that of the weft, and the above-mentioned problem is solved by forming the ears on both side ends of the above cloth.

[0007]

[Embodiment of device]

 The bandage (1) is woven from warp threads (2) and weft threads (3). The warp yarn (2) is made by coating the surface of an elastic core yarn with cotton, chemical fibers, synthetic fibers or other appropriate fibers, and other elastic yarns (5) and non-elastic yarns (6) such as cotton yarn or cotton blended yarn. The elastic yarn and the inelastic yarn are usually arranged in a ratio of about 1: 1 to 1: 6, and both yarns are arranged uniformly. In the case of the one shown in the figure, this ratio is set to 1: 2, that is, two non-elastic yarns are sandwiched between elastic yarns so that the elastic yarns come to both ends of the cloth. I am The elastic yarn and the inelastic yarn may have a ratio other than the above.

Further, the breaking strength of the weft (3) is about 50 to 300 g, and the breaking strength of the warp (2) is weaker than that of the adopted weft. The weft yarn (3) has a weight of about 240 to 250 g, and the warp yarn (2) has a weight of about 180 to 210 g (these numerical values are values in the state where the self-adhesive described below is attached).

The density of such warp (2) rows can be set to an appropriate value depending on the application, but normally it is good to set about 3 to 30 threads per 1 cm of width, and to 21 threads in the illustrated case. Has become.

A weft (3) is driven into the warp (2) row to form a cloth (4). As the weft yarn, an appropriate non-elastic fiber such as cotton yarn, chemical fiber, synthetic fiber or blended fiber can be used, but in general, it is often preferable to use cotton yarn in consideration of air permeability and hygroscopicity. The weft yarns are formed by stretching the elastic yarns and striking the non-elastic yarns so that they do not come loose and striking the warp yarns aligned and woven.

As shown in the figure, the weft yarns are formed in a wide space (8) and a narrow space (9) between adjacent wefts as if they were woven with two wefts. The slack part of the thread is mainly located in the wide part, so that the slack part of the non-elastic thread does not protrude from the surface and a smooth and non-textured surface is obtained. In addition, at that time, there is no slippage between the warp and the weft, so each weft keeps a constant interval, and the wefts are partially dense or sparse and unevenly distributed. The texture can be maintained in a uniform state.

The wide portion (8) of the weft row is usually formed to be about 1 to 3 times the space between the warp rows, and the narrow portion (9) is formed to be about 1/2 to 1/6 of the space between the warp rows. However, this interval is not limited to this.

Ears (10) are formed at both ends of the cloth (4). The ears are formed by striking the weft (7) on the warp (2) at one side end (11) of the cloth, and the weft (7) loop at the other side end (12). (13) is formed, and the weft that is folded back next to this loop is sunk through.Thus, both ears of the weft are used to hang the weft on the warp, or a loop is formed on this loop. The weft thread can be passed through or otherwise suitable.

On the surface of the cloth thus formed, a self-adhesive (14) containing an acrylic or other synthetic rubber latex, a natural rubber latex, a mixture thereof, or the like as a main component is sprayed and rolled. It is attached by an appropriate method such as a tar method or a dipping method. The amount of the self-adhesive to be adhered is preferably such that it does not impair the air permeability by closing the texture of the cloth.

This bandage (1) is wrapped around a winding core (15), and when this is used, the end is applied to the affected area that has undergone treatment, etc., and it tends to stretch slightly in the longitudinal direction (length direction). Then roll it up. At that time, the ears on the side of the bandage do not cause the thread to be frayed, so that it is easy to wind and the winding is difficult. Once the wound is protected, the part of the side edge of the bandage is pinched with both hands and pulled laterally, the bandage is easily torn laterally, so the torn end is pulled and rolled. When it is placed on the bandage and lightly pressed, the self-adhesive agent firmly fixes the terminal end and does not allow the wrapped bandage to be unraveled.

[0016]

[Effect of device]

 Since the present invention has ears formed at both ends of the cloth woven with the warp and weft as described above, when the bandage is wound, the thread is not frayed easily and can be wound neatly. Also, since the warp has a weaker breaking strength than the weft, the warp can be cut along with the weft, and it is easy to cut and has good hand-cutability. Moreover, if weft yarns are formed alternately in the narrow gaps and the wide gaps, when the elastic yarns of the warp are contracted, the loosened inelastic yarns are accommodated in the wide portion. Since it does not come out or wrinkle, it does not have dryness and itching does not occur, and since it is cut from the wide part, the weft thread does not get in the way when cutting and it can be smoothly cut by hand. it can.

Further, in the case where one side portion is formed by hanging it over the warp threads on the side end portion of the cloth and the other loop portion is formed with a weft thread, and the weft thread to be woven next is passed through, the loop is formed. The ears that are formed by hanging on the warp are thinner than the ears that are formed by the loops.Therefore, if you position the hung ears in the unwinding direction, the ears will be formed. However, it does not need to be bulky, and it can be used as a guide to which side to use when reusing the bandage due to the difference in the shape of the ear.
