A wide bandage fabric web has already been proposed which comprises a self-adhesive or adhesively coatable fabric with a crepe structure that is highly longitudinally elastic in the warp, easily torn in the weft direction, and has a crepe structure, in particular for bandages Fixation for distorsions, dislocations, minor fractures and for the prevention of sports injuries, which is designed in such a way that in the warp threads made of cotton, rayon or cotton / rayon and polyurethane or Rubber and weft threads made of cotton, rayon or the like. loading. standing tissue metal oxides or metal salts are embedded.

Also known are elastic bands made of cotton or crimped synthetic materials which are cohesive. The advantage of these sanitary napkins is that they are relatively slip-proof thanks to their special equipment and do not adhere to skin, hair or clothing, however have the disadvantage that they are either difficult to tear or impossible to tear at all, so that the doctor or the patient, if * »r only wants to use a small part, you have to use scissors *

The object of the present invention is to make such a material highly longitudinally elastic in the warp and light in the weft direction Einreißbaras to improve wide bandage and the known elastic bands made of cotton or crimped synthetic materials that are designed to be cohesive to remedy the disadvantages and in particular a solid,

The spinning of the polyurethane or rubber thread can be done with cotton, Spun rayon or polyfilen textured synthetic threads are made.

Of course you can these spinning crepe threads or twisted crepe threads are replaced by thin, textured polyfilament synthetic threads. Also thin braided polyurethane or braided rubber threads can be used.

Due to the transverse and longitudinal elasticity with a strong crepe structure, bandages are created with the highest level of modeling ability and plasticity created that can adapt to the body parts, especially joints, with the smallest radius.

In order to increase the tear in the weft and warp direction, which is already part of the construction is - spider crepe threads, twisted crepe threads - the tissue is additionally subjected to a chemical treatment in order to to achieve an intercalation of titanium dioxide, silicon dioxide, aluminum oxide or metal oxides with similar properties. Also metal salts such as silicates, carbonates, sulfates and the like, as well as plastic polymers such as formaldehyde-urea resin or melamine resin, can be used to increase the tear strength in the weft and warp directions Find.

Due to the high elasticity and compressibility in the warp and weft direction, depending on the indication by the strength the elastic elements can be adjusted, whereby the highest elasticity is achieved, can be made from the wide fabric web according to the invention as fixation bandages and compression bandages after sprains, dislocations, fractures and similar injuries and as a preventive measure against sports injuries. These bandages can also be used for variceal obliteration * for chronic and inflammatory venous congestion, for ulcera cruris, for lymphatic Edema, congestive dermatoses and all manifestations of the varicose symptom complex are used. Because of the light Tearability in the weft and warp direction is easy handling of the bandage by the doctor, as this depends on If necessary, a piece can only be torn off. It is no longer necessary that individual sections of the bandage by means of a

7726819 12/01/77

Scissors, a knife or the like. must be separated. the The doctor thus has the possibility, in the simplest way, of fabric with high longitudinal and high transverse elasticity in the warp and weft directions by tearing in the weft and warp directions of the desired fabric sizes. There is also one in the longitudinal direction Edge pressure coating to prevent the warp threads from escaping. Once torn off, the end can simply be pressed onto the remainder of the napkin without any other fastening means. The warmth of the hand creates a stable Liability achieved. This type of attachment is particularly important in sports, since it is not uncommon that the usual metal clips like a weapon act and often tear open the muscles on the lower leg, etc.

In the drawing, the invention is shown as an example, namely shows:

The dimension of the wound polyurethane or rubber thread as well as the number of wound polyurethane or rubber threads depends on the work capacity - tensile capacity - and the Extensibility, in terms of the weft and warp direction. The ratio can be between the braided polyurethane resp. Rubber fei dan to the crepe threads both in weft and in Ketrrichtung 1: 1, 1: 2, 1: 3, 1: 4 etc., whereby the spinning crepe threads or the twisted crepe threads are in the same direction of rotation change continuously, i.e. a spider trail with a direction of rotation is followed by a spider trail with a direction of rotation Z and follows a twisted crepe path with direction of rotation S. a twisted crepe path with direction of rotation Z or two crepe paths with direction of rotation S are followed by two crepe paths with direction of twist Z or two twisted crepe threads with twist direction S are followed by two twisted crepe threads with twist direction Z and the like. But there can also be spider's creeper paths like ' twisted crimp threads with the same twist are also used. Also the spider crepe threads and twisted crepe threads can be used as well in the weft as well as in the warp direction in a ratio of 1: 1, 1: 2, 1: 3 etc. follow one another and are combined.

can be additionally braided with such a combination Polyurethane and rubber threads are added. Spider crepe threads with twisted crepe threads of the same twist can also be used be combined. The dimension of the wrapping threads used in the weft direction, wrapped polyurethane or braided rubber threads can vary very widely in the area of the exemplary embodiment. The covering thread can used as a single thread, plied or twisted thread will. Textured polyfilament synthetic threads can also be used and can also be used as weft threads.

The fabric contains metal oxides or metal salts 4o or synthetic resins, such as formaldehyde resin, melamine resin or the like. , stored (Figures 3 and 4). It is also possible to coat the fabric with metal oxides or with metal salts or synthetic resins. By connecting the fabric structure with the inclusion of metal oxides, metal salts or synthetic resins, a good one becomes Tear capacity in the weft and warp direction and thus a Easy removal of tissue pieces desired by the doctor, in terms of length and width, possible. The directions of the tear are indicated in Fig. 1 by the arrows X and Xl. Taking into account the dimension of the spinning and twisting threads in In the weft and warp direction, it is conceivable to also achieve longitudinally and transversely elastic fabrics that only work in one direction are tearable.

A bandage which does not adhere to skin, hair and items of clothing, in which only the individual tours adhere to themselves, is obtained by the fact that the above described Fabric in the dipping, splashing, spraying, reverse transfer process or knife-coating impregnated with latex and anti-aging agents is coated or impregnated on both sides and then cut to size accordingly. This latex layer is indicated at 20, 21 in the exemplary embodiments shown in FIGS. 3 and 4. An aqueous emulsion of 2,6-di-tert-butyl-4-methylphenol is used as an anti-aging agent.

The anti-aging agent particles are shown in FIGS. 3 and 4 3o indicated. Of course, these fabrics can be coated on one side with the adhesive known in bandage technology, in accordance with the plaster bandages, in order to achieve highly modellable bandages. From these Adhesive binding can then be removed by the doctor by tearing in the weft and warp direction, as is the case with self-adhesive bandages. Furthermore Rigid-edged tapes with the same fabric structure and the same physical behavior can also be used with the same equipment.

Despite the high extensibility and compressibility in the weft and warp directions, which are controllable, the bandage made from the wide fabric is light in the weft and warp directions

tearable and easy for the doctor to handle, namely by the doctor separating the bandage according to the indication by tearing in the weft or warp direction and pressing the end onto the fixing part. A pressure coating on the edge of the bandage prevents the warp threads from escaping.
