The twisted single threads can also be replaced by twisted twisted cotton and / or staple fibers or twisted cotton / staple threads with different twists (twisted threads with Z and S twists).

The warp thread structure preferably comprises warp threads 113, 115, 11a, 11a, which in the form of spun or twisted crepe threads are arranged symmetrically relative to each other with opposite twisting directions and in particular in the ratio 1: 1, 1: 2 and so on. and are made of cotton or staple fiber and / or cotton / staple fiber. It is also possible to use spun or twisted crepe threads with the same twisting direction. The thread 116 is a polyurethane or rubber thread which is covered with cotton or staple fiber.

The following has proven to be suitable: For warp threads llh, llüa approximately 17 tex cotton l950 r.p.m. Z, for warp threads 115, ll5a 17 tex cotton 1950 r.p.m. S. In addition for warp threads llü, llüa lä tex x 2 cotton 2250 r.p.m. Z, for warp threads 115, 115a lä tex x 2 cotton 2250 r.p.m. S and for warp yarns 16, 156 dtex polyurethane coated with single, twisted or twisted yarns 7807497-8 of cotton and / or staple fiber or a mixed yarn of cotton and staple fiber or a woven polyphilic synthetic yarn. However, it is also possible to use other materials, dimensions and torsional values as well as other combinations thereof.

Preferably, the warp yarns of the fabric are spun crepe yarns of cotton or staple fiber and / or cotton / staple fiber, which are twisted in opposite directions with the following dimensions: Approximately 1590 r.p.m. 25 tex Approximately 1780 r.p.m. 20 tex Approximately l95O r.p.m. 17 tex Approximately 2100 r.p.m. lä tex Approximately 2250 r.p.m. 12, 5 tex Approximately 2150 r.p.m. 20 tex x 2 Approximately 2200 r.p.m. l7 tex x 2 Approximately 2250 r.p.m. lä tex x 2 Approximately 2500 r.p.m. 12.5 tex X 2 The dimensions of the coated polyurethane and / or rubber thread as well as the number of coated polyurethane and / or rubber threads depend on the working energy (deformation energy) and the extensibility “The relationship between coated polyurethane and / or rubber threads and crepe threads can be 1: 2, 1: 3, lz fl etc. wherein the spun and / or twisted crepe threads continuously change the twisting direction, i.e. a spun crepe thread with twist direction S is followed by a spun crepe thread with twist direction Z, a twisted crepe thread with twist direction S is followed by a twisted crepe thread with twist direction Z, two spun crepe threads with twist direction S follow on two spun two crepe threads with twist twisted crepe threads with twist direction S follow two twisted crepe threads with twist direction Z and so on. However, it is also possible to use spun and twisted crepe threads with the same twist direction.

In this embodiment, the dimensions of the covering threads can vary within wide limits. Simple, twisted or twisted threads can be used as covering threads, it being also possible to use a woven polyphilic synthetic thread. In the weft direction, the fabric preferably has spun or twisted crepe threads of cotton or staple fiber and / or cotton / staple fiber twisted in the opposite direction. The dimensions can e.g. be Approximately 2250 r.p.m. lä tex x 2 Approximately 2300 r.p.m. 12.5 tex x 2 Approximately 1590 r.p.m. 25 tex Approximately 1780 r.p.m. 20 tex About 1950 r.p.m. 17 tex Approximately 2100 r.p.m. lä tex Approximately 2150 r.p.m. 12.5 tex Approximately 2150 r.p.m. 20 tex x 2 Approximately 2200 r.p.m. 17 tex x 2 The yarns mentioned above can also be combined in the weft direction with coated polyurethane and rubber and / or woven polyphilic synthetic threads with corresponding ratios to the warp.

The dimensions of the coated polyurethane and / or rubber threads as well as the number of coated polyurethane and / or rubber threads depend on the working energy and extensibility, which applies to both the warp and weft directions. The ratio between the coated polyurethane and / or rubber threads and the crepe threads in both the warp and weft directions can be 1: 1, 1: 2, 1: 3, 1: H, etc., with the spun and / or twisted crepe threads continuously changing in the twisting direction, ie a spun crepe wire with twist direction S follows a spun crepe wire with twist direction Z and so on. However, it is also possible to use both spun and twisted crepe threads with the same twist direction.

The spun and twisted crepe threads can follow each other in both the weft and warp directions in a ratio of 1: 1, 1: 2, 1: 3, and so on. and they can also be combined. Additional coated polyurethane and rubber threads can thus be used in such combinations. Spun crepe threads can also be combined with twisted crepe threads with the same twist direction. According to the exemplary embodiments, the dimensions of the sheath threads in the coated polyurethane and / or rubber threads used in the weft direction can vary within wide limits. the overcoat threads can be used as a simple, twisted or twisted thread. It is also possible to use 7807497-8 woven polyphilic synthetic threads, also as weft threads.

Metal oxides and / or metal salts H0 or synthetic resins, such as e.g. urea resin, melamine resin or the like can be included in the fabric (Figures 5 and 6). It is also possible to coat the fabric with metal oxides and / or metal salt or synthetic resins according to the present embodiments. By connecting the tissue structure with inclusions of metal oxides, metal salt or synthetic resins, a good tear ability is achieved in both the weft and warp directions so that a doctor can easily tear off tissue sections of the desired length and width. While it adheres to the dimensions of the spun and twisted crepe threads in the weft and warp direction, it is also possible to think in the longitudinal and transverse directions of elastic fabrics, which can be torn in only one direction.

A bandage which does not adhere to skin, hair and clothing, in which only the separate turns adhere to each other, is achieved by the above-described fabric of Figures U-6 and also by that described in Figures 2-5 if impregnated by dipping , spraying or transfer processes or by dyeing, by coating or impregnating on one or both sides with a latex containing an anti-aging agent and then cutting to the correct size. The latex layer is shown in the embodiment of Figures 5 and 6 at 120, 121. The anti-aging agent used is an aqueous emulsion of 2,6-di-tert-butyl-4-methylphenol.

The anti-aging particles are shown at 150 in Figures 5 and 6. It is apparent that this fabric, like a patch on one side, can be coated with the adhesives known in the art of bandaging to obtain well modular bandages. In the same way as with self-adhesive bandages, a doctor can thus obtain the desired sizes of these self-adhesive bandages by tearing off the same in the warp or weft direction fl Aging-resistant bandages with the same tissue structure and physical characteristics can be used in the same way.

Despite the high adjustable extensibility and compressibility in the warp and weft directions, the bandage made from the wide fabric can be easily torn in the warp and weft directions and it is easy for the doctor to use the bandage by tearing it in the warp and / or the weaving direction according to the need and then to press its end to the fastening part. The yarp threads are prevented from protruding through an edge cone on the bandage.

The wide bandage fabric 210 in Figures 7 and 8 preferably comprises a fabric section of large length and predetermined width and it can also be rolled into a roll, from which a fabric section 211 can be removed.

The woven portion 210a according to Figures 7 and 8 comprises a fabric with warp threads 21H, Zlüa, 215, 215a, 216 and weft threads 217. The weft threads 217 may be made of cotton, staple fiber or a mixture of cotton and staple fiber or other materials.

The warp yarn structure preferably comprises threads 21l, 215, 21la, 215a of normal cotton, staple fiber or cotton staple fiber yarn preferably of 10, 12, sheath, 17, 20, 25 or 30 and the like and polyurethane and / or rubber yarns 16 coated with cotton or staple fiber. The warp thread 16 is e.g. of polyurethane of lšö dtex with simple, twisted or twisted threads of cotton and / or staple fiber or a blend yarn of cotton and staple fiber. However, it is also possible to use other materials, dimensions and torsional directions or other combinations thereof.

The dimensions of the coated polyurethane and / or rubber thread as well as the number of coated polyurethane and / or rubber threads depend on the working energy. The ratio between the coated polyurethane and / or rubber threads 216 and the remaining warp threads 21%, 21lMa, 215, 215a may be lzl, 1: 2, 1: 3, lzü, etc. wherein the wires 2lh, Zl fl a, 215, 2l5a may have the same or different twist directions.

The dimensions of the overlay yarns of the warp yarns 216 at the wide bandage fabric 210 of Figures 7 and 8 can vary widely. Simple, twisted or twisted threads can be used as overlay threads.

As in the previous example, it is also possible to include metal oxide or metal salt 218 or synthetic resins such as urea resin, melamine resin or the like in the fabric 210. As indicated at 220, 221 in Figure 8, it is also possible to use a latex coating. An aqueous emulsion of 2,6-di-tert-butyl-H-methylphenol was used as the anti-aging agent and the anti-aging agent particles are indicated at 230 in Figure 8.

The invention is not limited to the embodiments described and shown above. It is also possible to have a different construction of warp and weft threads for the fabric, while different surface treatment agents can be used to improve the tear characteristics of the fabric.
