[0001] The present invention is formed from at least three layers, namely a carrier layer having an inner surface _T, an intermediate layer, and a cover layer having an inner surface _D Budesonide and relates to. The intermediate layer is disposed between the carrier layer and the cover layer.

Background Art

[0002] Making the temperature uniform with the skin by having a cooling medium Budesonide is already known.

[0003] US 2002 / 0132091 A1 describes a fiber layer having a coating of PCM material on the upper and lower sides Budesonide and is described.

[0004] WO 2010 / 044657 A2 describes a laminate material for footwear manufacturing. The laminate material consists of a sub - laminate having a stretchable carrier layer and a further stretchable layer, and a further layer containing a PCM material is provided.

[0005] DE 20 2011 001 473 U1 describes a flexible flat structure having a PCM material. A heat exchange medium in thermal conductive contact with the PCM material is also provided.

[0006] The present invention is based on the problem of forming and arranging Budesonide so that the property of uniformly making the temperature good, that is, a good cooling effect is achieved.

Summary of the Invention

[0007] According to the present invention, this problem is solved in that the cover layer is formed from a base material and a functional material, and the cover layer has a cooling medium integrated therein. Thereby, the effect of the cooling medium, i.e., the property of equalizing the temperature with respect to the skin or the cooling effect, is surely improved. By means of a further intermediate layer, the basic cooling is improved and the cooling effect of the cooling medium is added thereto. The base material and the functional material can be manufactured independently of each other. That is, the mass ratio of the base material to the functional material can be freely selected.

[0008] The cooling medium is a so-called PCM (phase change material). The PCM can absorb body temperature or heat from the skin, thereby changing its state of aggregation at least partially from solid to liquid. When the body temperature or skin temperature drops again, the cooling medium releases heat again and undergoes a phase change to return to the solid state. In this way, a certain temperature equalization between the inner layer of the material and the body or skin is ensured.

[0009] The PCM used here becomes liquid at a temperature of approximately 28°C. For this purpose, the PCM absorbs body temperature and stores it up to a maximum temperature of 33°C. When the ambient temperature drops, the PCM becomes solid again and releases the heat stored in this process.

[0010] It can be assumed that the average temperature in the system drops linearly by 2°C. However, this also means that the temperature peak is divided up and down. Thereby, the formation of sweat is significantly reduced.

[0011] This temperature equalization is maintained by air exchange or air movement. This air movement is only possible by means of an intermediate layer in such a closed system. The air is trapped in the intermediate layer and displaced by the movement. Inside the system, i.e., inside the intermediate layer, due to this air movement, the warmer air moves to the cooler points. For this purpose, the intermediate layer can be woven into the carrier layer and the cover layer. Both the carrier layer and the cover layer can be designed as fabrics.

[0012] By incorporating, barriers such as the adhesive layer in laminated or bonded fabrics become unnecessary. As a result, the temperature-regulated air can come into direct contact with the temperature equalization cover layer, significantly improving the efficiency of heat exchange. For this reason, the structure becomes soft and fluffy, conforming to the support surface and the support shape.

[0013] Also, this problem is also solved by using the above-mentioned Budesonide for the manufacture of protective clothing, protective vests, protective trousers, bandages, shoes, headbands, hats, scarves, headgear, bandages, and gloves. Protective clothing can be particularly relevant to heat protection. Therefore, leisure clothing is also conceivable.

[0014] For this purpose, it can be advantageous if the base material is designed as a thread or fiber or knitted fabric and / or the functional material is designed as a thread or fiber or knitted fabric and has a cooling medium as a further component embedded in the thread or fiber. Both threads and knitted fabrics guarantee good gas exchange. If the base material is also in the form of a thread or knitted fabric, gas exchange is further improved.

[0015] Also, it can be advantageous if the intermediate layer is designed as a spacer fabric and forms a pile filament structure, and the pile filament structure consists of a plurality of filaments having a longitudinal axis _L arranged at a distance _a, and the plurality of filaments are aligned transversely with respect to the longitudinal axis _L in the direction _Q and transversely with respect to the inner surface _T and the inner surface _D. The pile filament structure is designed as a hair structure or a rod structure that maintains a distance between the carrier layer and the cover layer. This improves heat exchange in the intermediate layer and thus the cooling effect of the cover layer.

[0016] With this configuration, Budesonide has elasticity in the vertical direction, i.e., perpendicular to the surface, and the trapped air can move or be pumped. That is, with the movement of the user's body, the intermediate layer is partially compressed and the trapped air moves laterally.

[0017] Also, it may be advantageous if the filaments of the intermediate layer form an angle β with the inner surface_T and / or the inner surface_D, and 80° ≤ β ≤ 100°. If the angle is close to 90°, the rigidity of the intermediate layer increases. This is because the filaments are mainly subjected to pressure along the longitudinal axis_L by the cover layer and the carrier layer.

[0018] For this purpose, it may be advantageous if the filaments of the intermediate layer are arranged parallel to each other or enclose an angle α with each other, and α ≤ 30°. If the acute angle is as small as possible, the rigidity of the intermediate layer increases. This is because since the filaments are oriented in different directions with respect to the longitudinal axis_L, not only the force perpendicular to the surface of the cover layer or the carrier layer but also the force acting on the cover layer or the carrier layer at the above-mentioned angle β is well absorbed.

[0019] In the present invention, it may be particularly important that the intermediate layer has a basis weight of up to 200 g / m 2 (grams per square meter). This means that the fabric or clothing or protective clothing or protective gear to be manufactured can have an advantageous weight.

[0020] Regarding the design and arrangement according to the present invention, it may be advantageous that the cover layer is composed of a base material and a functional material including a cooling medium, and the proportion of the functional material in the cover layer is 20% - 60%, or 30%, or 40%, or 50%. The base material can be in the form of yarns or fibers. The functional material can also be in the form of yarns or fibers.

[0021] The higher the proportion of the functional material, the greater the mass of the cooling medium or paraffin. However, this does not fundamentally improve the temperature uniformity, and the time for temperature absorption and temperature release becomes longer. Also, when the proportion of the functional material exceeds 30%, problems may occur in the production of the functional material such as yarns.

[0022] Here, it may be advantageous if the functional material has a specific heat absorption of at least 50 J / g (joules per gram). In fact, 50 J / g is a value sufficient to continuously improve the wearing comfort of the Budesonide manufactured product. If the proportion of the functional material is 30%, a specific heat absorption of approximately 16 J / g can theoretically be achieved. This value can be affected by processing, particularly the coloring and finishing of the cover layer.

[0023] Also, it may be advantageous if the cover layer has a basis weight of between 230 g / sqm (grams per square meter) and 290 g / sqm, or between 250 g / sqm and 270 g / sqm. This way, at least the relative maximum value of the specific heat absorption is achieved. Even if the proportion of the functional material is increased beyond 40% or 30%, the specific heat absorption will not increase significantly. Since the specific density of the functional material is high, only the weight per unit area of the intermediate layer increases. Therefore, the optimal surface density is achieved using the above-mentioned proportion of the functional material with respect to the specific heat absorption of the cover layer. The optimal ratio between the specific heat absorption and the weight per unit area of the intermediate layer is achieved.

[0024] Also, it may be advantageous if a basis weight between 400 g / sqm and 600 g / sqm, or 485 g / sqm, or 550 g / sqm is provided. This way, Budesonide it becomes relatively lightweight.

[0025] Further advantages and details of the present invention are described in the claims and the specification and are illustrated in the drawings.
