Description

The invention relates to a textile assembly for covering a torso of a human being, comprising a back portion with a first textile fabric. The back part is arranged on a back of the person when the person is carrying the textile arrangement as intended.Textile arrangements of the type mentioned at the beginning belong in different configurations to the prior art and are usually worn by humans as exterior apparel. In this respect, such textile arrangements form an essential part of an upper apparel provided for humans.The textile arrangement serves on the one hand to provide an attractive appearance or an appealing aesthetic appearance for a person wearing the textile arrangement. In this function, the textile arrangement is subject to a personal printing-out means and to fashionable influences. On the other hand, the textile arrangement serves to protect the upper body of a person wearing the textile arrangement, for example from undercooling or from overheating.However, targets of protection with respect to the upper body can be non-uniform due to the situation, in particular depending on the environment, for example weather-dependent. Thus, the person wearing the textile arrangement may wish to avoid undercooling of arms and overheating of the back at the same time. Whereas the former is accompanied by unpleasant freezing, the latter causes the back to sweating as unpleasant. The textile arrangement must thus simultaneously prevent an undesired heat loss at the arms and allow a desired heat loss at the back.In other words, it is desirable that sleeves of the textile assembly oppose heat exchange with a human environment while the back facilitates heat exchange with the human environment.It is therefore an object of the invention to provide a textile arrangement for covering a torso of a human being, which arrangement enables an effective exchange of heat on the back side.An object of the invention is a textile assembly for covering a torso of a human being, comprising a back portion with a first textile fabric. Of course, the textile arrangement further comprises a front part which, when the textile arrangement is worn as intended, is arranged on a front side of the upper body, i.e. on a breast and a abdomen of the human. In addition, the textile arrangement usually comprises two arm parts, for short sleeves, through which an arm of the human extends in each case when the textile arrangement is worn as intended. All parts of the textile arrangement are permanently connected to one another and together form a clothing item for humans. The textile arrangement can be designed to also cover an abdominal region and legs of the person in addition to the upper body.According to the invention, the textile arrangement comprises a second textile material different from the first textile material, which is inserted into a recess of the first textile material and is non-detachably connected to the first textile material at an edge of the recess. The first fabric has a recess. Independently of the first textile material, the second textile material can ensure an effective exchange of heat on the back with a surrounding area of the person wearing the textile arrangement, namely in the region of the recess. The first textile material, on the other hand, can counteract a heat exchange with the environment and in particular be provided identically for further parts of the textile arrangement. The recess determines the effective area of the heat exchange. The second fabric determines the efficiency of the heat exchange.In one embodiment, a thickness of the second fabric is less than a thickness of the first fabric. The thickness of a textile fabric is to be understood as a thickness of the textile fabric, which is measured perpendicular to main extension directions of the textile fabric. The fabric may have more than one layer, i.e. be formed in multiple layers, whereby a thickness of the fabric is increased. Due to the lower strength, the second fabric ensures more efficient heat exchange with the environment compared to the first fabric.Alternatively or additionally, a density of the second fabric may be less than a density of the first fabric. The density of a fabric is understood to be an air permeability of the fabric. Due to the lower density, the second fabric ensures more efficient heat exchange with the environment compared to the first fabric.Ideally, the second fabric comprises an air-permeable fabric or the second fabric consists of an air-permeable fabric. The air-permeable fabric may be referred to as a mesh fabric or a mesh for short. The air-permeable fabric has a plurality of usually regularly arranged meshes which enable heat exchange by means of ambient air flowing through the meshes.In contrast, the first textile material can comprise a woven or a knitted fabric or consist of a woven or knitted fabric. The woven fabric and the knitted fabric are textile fabrics which have different structures. The fabric comprises at least two stringy grains commonly referred to as warp and weft. The knitted fabric comprises a yarn system with a plurality of loops interlaced with one another.The second fabric is advantageously joined to the first fabric by means of a seam. Seams are well-established connecting means for connecting fabrics. However, the invention is not limited to the seam, but covers any other connecting means suitable for connecting fabrics, for example an adhesive.The second fabric may be completely surrounded by the first fabric. In other words, the recess is a passage, i.e. an opening. Alternatively, the recess can also be formed as an indentation, i.e. have a lateral concave incision. Another variant of the recess is a missing strip of the first fabric, whereby the first fabric of the back part is divided into two separate sections.In particular, the first textile material can have a single recess. In this way, an effective heat exchange is ensured in exactly one region of the back. The recess can be provided, for example, corresponding to a region of the back which has a particularly high surface density of sweat glands.In one embodiment, an area of the second fabric is greater than an area of the first fabric. In this way, a particularly high effectiveness of the heat exchange is achieved.Advantageously, the second textile material fills the recess completely. In other words, the back part does not have a passage, whereby use of the textile arrangement, in particular an application or an extraction, is facilitated. In addition, the textile arrangement completely covers a skin of the back.A contour of the recess can be at least partially round and / or at least partially straight and / or can have at least one corner. The contour can be circular, elliptical, oval, polygonal, polygonal with rounded corners or can have a combination of round and straight sections. The contour can be adapted to a contour of a region of the back which is particularly in need of cooling. As an alternative or in addition, it is of course also possible for modal aspects to determine the contour.The recess advantageously has mirror symmetry. The mirror symmetry gives the recess a particularly aesthetic appearance. The recess, more precisely the contour of the recess, can have a plurality of mirror balances.The back part can have mirror symmetry. A lateral mirror symmetry with respect to a mirror axis which extends parallel to a spinal column of the person wearing the textile arrangement is particularly advantageous.In particular, the recess can be arranged centrally with respect to an axis of symmetry of the back part. The central arrangement of the recess gives the back part a particularly aesthetic appearance.In one embodiment, the first textile fabric or the second textile fabric comprises a synthetic fiber and / or a natural fiber or the first textile fabric or the second textile fabric consists of a synthetic fiber and / or a natural fiber. The synthetic fiber is also referred to as a chemical fiber and comprises natural or synthetic polymers. Synthetic fibers of polyester, polyamide or elastane are listed by way of example and not by way of limitation. Natural fibers include vegetable fibers, animal fibers, and mineral fibers. Natural fibers of wool, silk, cotton or flax are listed by way of example and not by way of limitation.For example, the textile arrangement can be designed as a pullover, a hood pullover, a jacket, a sweat shirt, a T shirt, an overall, a shirt, a blouse or a clothes. Puller, hood pullover, also referred to as hoodie, jacket, sweat shirt, t shirt, shirt and bluse exclusively coat the upper, while the overall and the clothes also coat the abdomen and at least partially the legs. The list of garments is not exhaustive. The invention also covers other garments for covering a human upper body.It is understood that the textile arrangement is equally suitable for female and male humans, i.e. for women and men.A substantial advantage of the textile arrangement according to the invention is that it prevents an unpleasant sweating of the back without being accompanied by likewise unpleasant undercooling of other regions of the upper body or of arms. In particular, a hoodia according to the invention worn at a comparatively low temperature in winter allows seating on a sofa without back-welding or lie on a bed. Or a shirt according to the invention worn in summer with strong wind enables a back-weld-free stay on a sunny beach.Further advantages and features of the invention are explained with reference to the drawings with reference to an embodiment of the invention. This shows FIG. 1 shows a textile arrangement according to an embodiment of the invention for covering an upper body of a human being.FIG. 1 shows a textile arrangement 1 according to an embodiment of the invention for covering an upper body of a human being.
