Description

The invention relates to a garment containing a textile frame material that covers a portion of a user's body, and on the side of the frame material that faces this portion of the body, an adhesive layer is disposed on the frame material, which, when used for the intended purpose, contacts the specified body area, and this textile frame material without an adhesive layer when a certain tensile load is applied is stretched by a first value reversibly lengthening.

Garments of the kind indicated at the beginning are used in the field of sports and in medicine in order to create compression on certain desired areas of the body. In this case, stimulation is performed, which usually acts in a circular direction, for example, in the area of the arm or leg, in order to improve venous blood flow and counteract thrombosis or lymphatic edema.

In this case, various methods are used to affect the biomechanical functions of the user's body. At present, among others, basic compression and the use of various so-called teips (patches) or zones with high tensile strength are used. These technologies work with a differentiated clamping force, which different tensile properties (applied tensile load) of different zones of clothing exerts on the user's body. Direct contact of active materials with the skin and direct effects on the skin, as is postulated, for example, in the so-called kinesiology taping (Kinesiology Taping - kinesiologisches Taping, see below), does not occur with these technologies.

Another purpose is to support the joints and, accordingly, their fixation. It should be mentioned, for example, application in the knee area, when the patella is left free. In connection with this concept, reference should be made to an article of clothing of the genus indicated first, known from EP 1 810 649 B1. This publication describes a tight-fitting garment that is provided with a material with a high coefficient of friction on the side facing the user's skin. To limit the movement of muscles, joints and other parts of the body in order to prevent the formation of bruises, bruises, muscle sprains, joint injuries with sprains, bone fractures, and other injuries, a bandage is used, and the formation of a material with a high coefficient of friction in such a way that its elasticity is lower than the elasticity of the textile frame material. The mobility of the fabric with which the material with a high coefficient of friction contacts is thereby deliberately limited by the mobility of this material.

However, there are both the use of the basic function of unlimited circular compression and the use of modifications with local compression. By unlimited circular compression is meant a pressing force created by a tight garment, which exerts textile material on the user's body. This effort should be definite and decrease from the periphery in the direction of the heart - i.e. from the distal side to the proximal. By reducing the cross section of venous vessels, in any case at rest, blood circulation is enhanced, and the output of metabolic products is accelerated.

The described technologies work on a simple principle, according to which this voltage (force) is largely determined by the material of the garment and has a non-specific effect on the body. Such compression garments are known as sportswear for enhancing results as well as for regeneration. There are articles of clothing with general compression or with specific clamping force.

In this case, materials with various extensibility are usually used, if necessary with so-called teips (plasters) placed on the outside or, respectively, with laminations. There is no direct effect on the skin.

Utility model DE 20 2010 016 255 U1 discloses a retaining openwork rim (elastic band) that fits between the garment and the wearer's skin to prevent this garment from slipping off. US 2006/0154053 A1 wird describes an adhesive textile material that should adhere to a user's skin. US 2008/0236417 A1 discloses coating stockings and socks to minimize the risk of slipping on a user's skin.

The so-called kinesiological taping was developed by Japanese chiropractor Kenzo Kase. About 30 years ago, he created a special patch (teip), which has high elasticity, is breathable and pleasant to the skin. It adheres to the skin like a second skin. With any movement, it stretches and contracts again, without restricting the freedom of movement. Compared with other plasters and bandages, the muscles are not unloaded so much that they degenerate. Instead, the skin through such an elastic teip with each movement is very gently tightened and massaged. The flow of lymph and blood is activated, and the metabolism in the muscles and tendons is stimulated. As a result, stress is relieved, and inflammation resolves.

Kinesiotapeing is usually used to protect certain muscle groups from damage, as well as simply to enhance the athlete's achievements.

Kinesiotapeing is currently used in highly elastic cotton bandages. Such a teip is glued to the skin along the corresponding muscle fibers, which must be supported or stimulated. The teip has the same elasticity as human skin, and it is placed on the skin without additional stretching. This ensures that the teip will not create additional mechanical support. Teip stimulates muscle fibers and metabolic processes under the skin, improves biomechanical performance and promotes relaxation.

The basis of this invention is the task of creating a garment, in particular in the form of trousers or the upper part of a suit for sports purposes, in which it is possible to simply and effectively exert a stimulating effect on the skin, and the effect that occurs during kinesiology taping is used.

According to the invention, the solution to this problem is characterized in that the textile frame material, together with the adhesive layer, when a tensile load is applied, is extended by a second amount of reversible elongation, which is at least 65% of the value of the first amount of reversible elongation, and this garment is tailored so that under elastic stress, it fits the part of the user's body covered by this garment, and this garment is tightly attached to the skin of the user and, thereby, creates t a certain compression, which ensures the adhesion of the adhesive layer to the skin.

Preferably, the second reversible elongation is at least 75% of the value of the first reversible elongation.

Thus, it is proposed - in contrast to the above prior art according to EP 1 810 649 B1 - a garment of textile frame material on the inside, i.e. on the side facing the user's skin, to provide an adhesive layer, however, this adhesive layer is formed in such a way that the tensile strength is increased to a minimum, which is expressed by the indicated change in the magnitude of the reversible stretching, which inevitably occurs if this adhesive layer is placed on the textile frame material.

A preferred implementation of the claimed concept provides that the adhesive layer is applied to the textile frame material in the form of strips. At the same time, several zones of the adhesive layer running parallel to each other and having the shape of strips can be placed on the textile frame material.

This adhesive layer can be placed on the textile frame material and wave-like, and in this case it can also be provided that several wave-like zones of the adhesive layer running parallel to each other are arranged on the textile frame material.

The adhesive layer can be applied to the textile frame material and in the form of a dot structure.

In any case, the proposed geometric design of the adhesive layer ensures that the additional mechanical tensile resistance that is created by the adhesive layer material additionally applied to the textile frame material remains minimal.

The adhesive layer, applied in the form of strips or wavy, can in this case pass in the direction of the provided longitudinal extension of the garment or also in the direction transverse to it. This longitudinal extension usually corresponds to the direction of the corresponding muscle fibers.

The adhesive layer preferably consists of silicone or at least contains silicone. This layer can be applied to textile frame material by printing methods, glued or laminated.

The textile carcass material preferably consists of polyester fiber. As an alternative solution, you can provide a textile skeleton layer of a block copolymer of components of polyurethane and polyethylene glycol (elastane). In one embodiment, a combination of polyester fiber and elastane can be used. In principle, it can be envisaged that the textile carcass material consists of a synthetic spun fiber that is combined with elastane.

Elastane is a highly tensile synthetic fiber and is similar to rubber, but it has higher strength and is more durable. Urethane forms rigid elongated segments that are joined to each other in the longitudinal direction and due to the creation of bonding forces of secondary valencies provide fiber adhesion. Rubber-like polyol blocks, in contrast, are strongly twisted into tangles, but can easily straighten. Due to this combination of rigid and elastic blocks, a very high elongation of more than 700% is achieved.

Thanks to the proposed embodiment, the adhesive layer is pressed against the skin surface, and due to the high coefficient of friction of the adhesive layer, its good retention on the skin is ensured.

Preferably, the adhesive layer material has a coefficient of adhesion (to the skin) that is at least µ = 0.4, preferably at least µ = 0.5. In contrast, the textile carcass material has a coefficient of adhesion (to the skin) which is not more than µ = 0.3, preferably not more than µ = 0.25.

The proposed garment is thus a shell adjacent to the body, which is on the inside, i.e. with the side facing the user's skin, provided with an adhesive layer, in particular printed or laminated. This film-shaped adhesive layer has a coefficient of friction that is different from the coefficient of friction of a textile frame material. These differences in the surface properties of the textile frame material and the adhesive layer when wearing this garment cause a stimulating effect, which, depending on the implementation, stimulates biomechanical functions, respectively, certain muscle groups or relaxes them. The placement and implementation of such zones can be carried out in accordance with the principles of the described kinesiotape.

The present invention thus uses the principle of kinesiotherapy and purposefully combines it with a garment. A print with a high coefficient of friction is applied as a film on a garment from the inside. The garment adheres tightly to the skin and thereby creates a certain compression, which ensures that the adhesive layer is pressed against the skin. Those areas that are equipped with an adhesive layer by printing method meet the basic principles of kinesiology taping.

It is essential that the adhesive layer is located inside the garment and, when using the garment for its intended purpose, adheres to the skin. Through the properties of the material of the adhesive layer, as well as through the structure, targeted manipulations with body functions can be carried out.

This stimulating effect is created only due to the various properties of the static friction of the textile frame material and the adhesive layer. Unlike other solutions already known (see EP 1 810 649 B1, analyzed above), no mechanical reinforcement due to increased tensile strength should be caused. This means that only the user's muscular strength must be applied. Therefore, muscle tone is maintained and, accordingly, trained.

Thus, an essential aspect of the proposed solution is that the tensile strength of the textile carcass material is kept at a minimum level or is accordingly limited in order to achieve the indicated stimulating effect due to various friction coefficients of the textile carcass material and the adhesive layer and due to as much movement as possible.

The most preferred applications should include the following.

First, targeted muscle stimulation can be performed. For this purpose, adhesive layers are placed along certain muscle trajectories on a textile skeleton material. Application of the layer is carried out by printing methods on fabrics or by lamination. Provided with an adhesive layer, the zones stimulate the surface of the skin due to stronger adhesion compared to textile frame material. It is important to ensure that this tensile strength with respect to the carcass supporting material remains as constant as possible or changes only minimally. The zones provided with an adhesive layer adhere to the skin, while the clean textile zones allow easy gliding. Inconsistency between adhesion and gliding leads to skin stimulation in the adhesion zones. This stimulation is transmitted to the underlying muscle fibers and layers of the skin and locally affects the muscle and metabolism.

Secondly, lymph flow can be stimulated. To do this, adhesive layers are placed along certain trajectories, which are also applied to the textile frame material by printing onto fabrics or by lamination. And in this case, the skin surface is stimulated due to the difference in the friction coefficients of adhesion of the adhesive layer and the textile frame material. And here it is important to ensure that the tensile strength relative to the textile frame material remains constant or changes only slightly. These treated areas cause adhesion to the skin, while clean textile areas allow easy gliding. And in this case, this inconsistency between adhesion and sliding leads to stimulation of the skin in the adhesion zones. The resulting stimulation is transmitted to the lymphatic vessels lying under these zones and stimulates the removal of waste products and tissue fluid. The prerequisite for this is that the pressing force that the garment exerts on the body due to the textile frame material and the cut of the garment increases as it moves away from the heart and, thereby, transports lymphatic fluid towards the lymph nodes and from the extremities to the center body, and, thus, to the organs of excretion.

One of the preferred implementations of the proposed concept in relation to the desired and necessary differences in the friction coefficients of adhesion is to apply by printing, gluing or laminating silicone, which is characterized by a high coefficient of friction of adhesion, while at the same time providing high tensile ability and elasticity, which allows it to be used on large surfaces in compression products. Due to this, the extensibility of the textile frame material, i.e. tissue is not significantly limited; besides, plunging is prevented.

In the proposed concept, different friction coefficients of different materials used are used. Areas with a greater or lesser adhesion are deliberately created, which cause stimulation of the skin surface. This opens up a new range of medical and psychotherapeutic technologies that can be implemented through a piece of clothing through physical stimulation of the skin surface. It is important that skin stimulation is carried out without additional mechanical reinforcement with the help of hardened (reinforced) materials or parts with increased tensile resistance, i.e. so that, according to the principle of kinesiological taping, pure stimulation of the skin surface and the underlying layers is ensured.

Due to the use of surface stimulation, in addition to a certain basic compression, a pressure load on the body can be set and the exact location of the stimulation zones can be established.

Thus, a garment for wearing on a body has been proposed, which has modified zones on the inside that differ in their physical surface properties and / or surface structures with respect to friction or, respectively, adhesion from the textile frame material of this garment.

The areas applied by printing or transfer (transfer) method, in comparison with the frame material of the garment, thus have a higher coefficient of friction, and these areas of adhesive layers have tensile strength, nevertheless very close to the tensile strength of the frame material (textile frame material).

Stimulation of the skin and upper layers of the body is ensured by the above properties of materials in combination with the surface structure and, accordingly, the shape of the adhesive layers. This is achieved preferably in combination with the already known compression technology.

In FIG. Figures 1-6 show different articles of clothing 1 in the form of sports trousers, the figures indicated by the letter “a” show the normal view of these trousers (front or side), and the figures indicated by the letter “b” show these pants turned inside out, i.e. inside out.

You can see that these trousers consist of a textile frame material 2, on which the adhesive layer 3 is placed. For this, methods of printing or laminating, as well as gluing, are used.

As you can see, the adhesive layers 3 have a predetermined configuration, which is selected so as to provide certain muscle stimulation and / or stimulate lymph flow.

In FIG. 7a-7d show another exemplary embodiment similar to FIGS. 1-6. Here, the adhesive layer 3 extends along the inner side of the sports pants 1 (the inner side of which is shown turned outward) in the form of strips. It should be noted that the strip-shaped structures presented here may be of one or more types, as shown in FIG. 10-12 (see below).

In FIG. 8a-8d, another embodiment similar to FIG. 1-6. In some areas, the adhesive layer 3 is made on a large surface (see the hip zone). The structures shown here, in turn, can be made of one or more types, according to FIG. 10-12.

In the embodiment of FIG. 9a and 9b show wave-like adhesive layers 3 that extend in the longitudinal direction of the leg. And in this case, the structures shown may also be of one or more types in FIG. 10-12.

Various possible embodiments of the adhesive layer 3 on the textile frame material 2 are shown schematically in FIG. 10, 11 and 12. Referring to FIG. 10, the adhesive layer 3 is made in the form of waves located parallel to each other. A cross-section of the carcass material 2 with an adhesive layer 3 is shown under the structure form shown in this figure.

According to FIG. 11, the adhesive layer is a continuous strip.

In the solution of FIG. 12, it is provided that the adhesive layer is configured as a point structure (preferably regular).

Due to the corresponding geometrical implementation of the adhesive layer 3 on the textile frame material, it is possible to achieve that the additional mechanical strength of the material of the garment with respect to the force required for stretching increases only minimally (which corresponds to the objective of the invention), so that the frame material 2 provided with the adhesive layer 3 It will not create a bandage effect, but, on the contrary, will follow the movement of the skin surface without exerting noticeable effort on it.

The location of the wave-like elements of the adhesive layer on the frame material also has an effect in this regard. In FIG. 13 it can be seen that several undulating, parallel to each other, strips of adhesive layer 3 are located on the frame material 2 so that the provided direction L of the longitudinal tension of the garment extends as if in the direction of these undulating strips. According to FIG. 14, the undulating stripes 3 extend in the Q direction, transverse to the L.

Accordingly, for the solution of FIG. 14 it is preferable to expect a smaller increase in tensile strength than in the case of FIG. 13.

In FIG. 15 shows once again how to understand the claimed solution.

In FIG. 15a shows a control strip of a certain width and height (for example, 10 mm × 100 mm), which consists exclusively of textile frame material 2. This control strip is fixed at one end 4 to a measuring device.

To the other end 5, as shown in FIG. 15b — a measuring force F ₀ is applied, for example, 50 N. This strip, free of the adhesive layer, is stretched by a first reversible elongation Δs ₁ .

A strip of textile carcass material is now provided with an adhesive layer, see FIG. 15c and FIG. 15d. According to FIG. 15c, the adhesive layer 3 in the form of wavy strips extends across the direction of extension. After applying a tensile load F _{0, a} second reversible elongation Δs _{2 is} measured, which, however, is not much less than the first reversible elongation Δs ₁ .

If the undulating strips running parallel to each other are located in the direction of extension, as shown in FIG. 15d, the adhesive layer 3 placed on the textile carcass material 2 will exert a tensile force F _{0 with a} slightly greater resistance, as a result of which the second reversible elongation Δs ₂ is slightly less.

In each case, the embodiment according to the invention is chosen such that the textile carcass material 3 together with the adhesive layer 3, when a tensile load F _{0 is} applied, is extended by a second value of Δs _{2 of} reversible elongation, which is at least 65% of the first value of Δs _{1 of} reversible elongation.

This ensures the achievement of the optimal massage, respectively, stimulating effect when wearing the item 1 of clothing without the need for undesirable in this case, strengthening, respectively, hardening the item of clothing through this adhesive layer.

In FIG. 16 is a diagram showing the values Δs of reversible elongations (in mm) that arise when a load F (in N) is shown for different embodiments of the garment.

Curve A shows the progress of the purely textile frame material 2, i.e. onto which no adhesive layer 3 is applied. A load of F ₀ causes a maximum first reversible elongation Δs ₁ (cf. FIG. 15b).

The application of a wave-like adhesive layer 3 extending in the transverse direction to the textile carcass material 2 (see Fig. 15c) leads, according to curve B, to only a slightly lower value of the second reversible elongation Δs ₂ when the load F _{0 is} applied.

This reversible elongation is still slightly reduced if, according to curve C, a wave-like adhesive layer 3 is applied extending in the longitudinal direction (see FIG. 15d).

However, the proposed materials, equipped with an adhesive layer 3, at a given load are significantly more flexible than those known from the prior art shown by curve D. Here, a bandage effect is achieved; therefore, the compliance of the material is significantly reduced if an adhesive layer is applied (see EP 1 810 649 B1).

According to the invention, the curves remain in the shaded area in FIG. 16, i.e. the textile frame material 2 together with the adhesive layer 3 when a tensile load F _{0 is} applied is stretched by a value Δs _{2 of a} reversible extension, which is at least 65% of the first value Δs _{1 of a} reversible extension.

Thus, muscle fibers or, accordingly, lymphatic vessels can be stimulated in a certain way. The exact course of these trajectories is laid on the basic garment. It is determined which printing technology, respectively, of lamination best conveys this functionality to the body, without significantly affecting the properties of extensibility and elasticity of the fabric. The input parameters in this regard are the thickness of the adhesive layer and its structure, as well as the surface properties of the applied material (mostly silicone). Then, the adhesive layer in accordance with the calculated form of its passage along the inner side of the garment is applied to the textile frame material.
